Bus explosion-proof security equipment application

From the bus burning incident in 14th bus in Yibin City in May this year to the bus and explosion accidents in Hangzhou and Guangzhou in July, several accidents were caused by artificial arson, and buses lacked the necessary security inspection facilities. It is impossible to prevent people from carrying flammable and explosive goods and other dangerous goods by bus, and these accidents are fundamentally impossible to eliminate.

In recent days, the Ministry of Public Security has convened an emergency video conference for public security agencies across the country to deploy and further strengthen the safety and security of subway transit. The Ministry of Public Security requires that strict strikes be strictly taken to prevent serious violent crimes in subway transit. Each subway train and each bus should be equipped with a safety officer and be equipped with the necessary protection and riot protection facilities and equipment. Strengthen the inspection and control measures for prohibited items, and the goods entering the station must be screened.

Explosion-proof security inspection equipment is a general term for equipment that carries out safety inspections on cargo, personal, site, and carrying items in order to prevent and stop explosions, strikes, and perpetrators. From the product category, it mainly includes security inspection, explosion-proof disposal and anti-terrorism equipment. Among them, security inspection equipment includes X-ray security inspection machine, security inspection door, hand-held metal detector, pass-through metal detection door, liquid detector, and detector , metal detectors (doors), explosion-proof disposal equipment, including explosion-proof tanks, explosion-proof blankets, robots, *** site investigation boxes, dangerous goods storage tanks and some ancillary facilities, etc., anti-terrorism equipment including portable frequency interference instrument, toxic gas detection Instrument and so on.

From the perspective of volume, it can be divided into large, medium and small-sized equipment. Large-scale security inspection equipment is mainly used for the inspection of goods, such as the container/vehicle detection required by railways, and has high technical requirements; medium-sized equipment is currently mainly used in passenger transport. For baggage and personal detection, small devices are mainly hand-held devices that are easy to move and carry.

Due to the particularity of the public transportation system, the explosion-proof security inspections for buses and bus stations still face many problems.

I. Problems faced by bus explosion-proof security inspection

On July 5th in the Hangzhou bus burning case, the suspicious liquid used by the arsonists contained the “banana water” component. If security checks were carried out, he could not take the car and he would be detained. Some people had previously attempted to place "banana water" in a bottle of mineral water. They wanted to get away from the train and were seized and detained by the police at the security device. The benefits of security are not controversial, but there are different voices if you want to implement bus security.

It is difficult to set the security inspection

Compared with public transport such as airplanes, trains, and subways, there are many bus trips, many stops, frequent passengers getting on and off the bus, there is no relatively closed operating environment, and it is difficult to set up artificial security links. Article 23 of the Fire Protection Law clearly stipulates that it is prohibited to carry flammable and explosive dangerous goods illegally into public places or to take public transport. Otherwise, it is punished according to the Law on Public Security Administration Punishments. An insider of a fire protection system told the reporter, but in the process of implementation, this law is very passive, and it is basically difficult to prohibit it. The public security fire department cannot send people to the bus to inspect the entire day. The main implementation of this piece is. The unit should be the traffic management department, but if they do not have related automatic detection devices, they will not be ideal for spot checks.

Increase in time cost

The main function of buses is low price and convenience. If security screening is implemented, the time for each station will increase. For fast-paced modern life, if the cost of transportation increases by one-third in time, many people may say that they cannot afford injuries. Some people have complained that they do not have enough sleep, or think that their children have less sleep time. After the security check, office workers and students must be able to get up earlier and feel unwilling.

Passengers have weak coping abilities and many secondary injuries

The reporter noticed from the Guangzhou accident surveillance video that many passengers ran off the bus before the explosion, but soon afterwards gathered to wait and see the bus. After the fire got up in a flash, he immediately rushed to the surrounding area to wait for the bus and wait and see. passenger.

In the previous Hangzhou bus arson case, neither the passengers nor the rescuers had yet mastered the correct method of breaking the windows. The correct method is to beat the four corners of the glass as much as possible to allow the glass to fall off as a whole, so as to prevent the living person from being scratched by the glass when jumping. After the firefighters arrived at the scene, they spotted blood stains on the scene. These bloods were mostly caused by incorrect methods of hitting the windows when the crowd rescued them, thus injuring themselves or being rescued.

Equipped with security staff, with good direction and difficulties

The Ministry of Public Security requested at the meeting that it is necessary to actively request the party committee and government to increase investment and deploy security personnel on each subway train and every bus. This measure has strong pertinence and is conducive to striking strictly against public violence crimes. At the same time, it must overcome some difficulties and actively promote it. A person in charge of a large bus company in Guangzhou introduced that the company currently has more than 10,000 bus drivers and nearly 10,000 vehicles. Because of treatment and other reasons, drivers and crew members have been in short supply, let alone equipped with security officers. "If the government does not bear this part of the cost, the bus company simply can not afford it.

Many times, we do not choose because a certain solution is perfect. Instead, we compare the two solutions. There are no other alternatives to the safety of buses that can be safely implemented. At present, the drawbacks of implementing security inspections are only increasing the time and cost. Failure to implement security inspections may be a loss of life and property to the individual and a social order. It may be seriously damaged. In contrast, we are of course willing to spend time in exchange for life and property security.

Second, there are precedents for bus safety inspection

With the rise of various security cases, more and more passenger stations, railway stations and other related companies or units have increased security explosion-proof measures to ensure safe operation. In the face of complicated situations, bus stations also need to deploy explosion-proof security devices.

For the explosion protection problem, a detector is placed near each security door to detect and immediately detect suspicious items. What is the core of security measures? Can you guarantee safety when you can? Many people have raised questions about this. Explosion-proof security technology has three cores:

Security door: Saying that the role of the security door is to set the initial value of the security door, control the shape and weight of the metal. When the metal carried by the person passing through the security door exceeds a set weight, quantity, or metal object shape as pre-equipment data does not match, a security door alarm is triggered. So that security personnel can promptly discover the metal items that the person carries.

X-ray security inspection system: When baggage parcels are transported to the detection box through the transfer belt, the X-ray security inspection system will perform ray scanning and generate X-ray images in the security personnel's video display equipment. This kind of technology makes use of the computer algorithm rule to make the current object be compared with dangerous goods, ie, ***. If the security personnel finds suspicious items through the screen display, it must be handled according to the dangerous goods solution.

**, *** detection system: It is a kind of detector based on ion mobility spectroscopy as the basis for identification, according to the unique molecular structure of each material vibration spectrum to detect, without opening the outer package of the test object, when found * When the object or object is in the air, the instrument automatically issues a prompt to remind the security personnel to carry out further hazard determination and problem solving.

At present, there are precedents for deploying the security inspection system in the BRT system. In Urumqi, the capital of Xinjiang Uygur Autonomous Region, a full-time security inspection staff will be added to the BRT platform. All passengers must carry electronic inspections. Drinks and other liquids must be opened before drinking. One can only enter the platform by car. With the frequent occurrence of violent and terror incidents in the recent period, since May 23, the Urumqi bus system has been fully upgraded. Passengers riding the BRT BRT are prohibited from carrying liquids and lighters.

In Chengdu, hand-held liquid detectors are installed at the entrances to 28 stations of the 2nd Ring Road of the Second Ring Road in the city. If you bring kerosene, alcohol, etc., you may not be able to get on the train. In addition, security personnel are equipped with anti-riot steel forks, anti-riot sticks, etc. in order to respond to emergencies. It should be pointed out that the security inspection of BRT implemented in Chengdu is different from that of subway, and it mainly takes the form of random sampling.

However, the bus system prevailing in the city does not have a closed system for BRT, and the layout of bus stations is relatively scattered. It is impossible to implement security inspection equipment and security checkers at each station. At the same time, there is no applicable bus system. Small security inspection equipment, so the bus system's market demand for security inspection equipment is very large.

Third, bus explosion-proof security inspection to apply mainly

At present, there are corresponding security products and solutions for airports, railway stations, subways, and even passenger transportation systems. However, due to the complexity of passengers in public transportation systems, the mobility is large, and the stations in ordinary public transportation systems in all cities are open. , get on and off the car more casual can not do similar security check at the airport railway station. From the point of view of various localities, choosing a flexible and applicable security inspection equipment combined with a flexible security solution can solve the problems faced by bus security inspections.

First of all, it is necessary to ensure the safety inspection of major hub stations and bus stops, and to ensure the safe driving of buses from the source. In addition, the bus stations have increased the frequency of job inspections, especially in the bus station to add personnel positions, timely control of the station abnormal situation, found suspicious persons, articles, vehicles and other situations immediately in accordance with the relevant emergency plan effective and proper disposal.

Secondly, according to the requirements of the Ministry of Public Security, security personnel are provided on each bus. The safety officer's duties are focused on safety assurance. At the same time, a hand-held detector is equipped to carry out random inspections of the passenger's corresponding baggage, and regular and irregular inspections are conducted. It can effectively prevent flammable and explosive products from being brought on board. At present, there are nearly 2,000 bus safety workers in Beijing, distributed on 19 bus lines in the city's core area. In the next step, according to Beijing’s anti-terrorism situation, security officers may be equipped with portable security inspection instruments and fire extinguishers and fire extinguishers. Blanket and so on.

Finally, the corresponding manufacturers should introduce a security inspection device suitable for buses as soon as possible, for example, a “simple safety instrument installed at the top of the door” proposed by relevant personnel, or an automatic detection device for dangerous goods at the bus entrance, when passengers carry such items. At that time, the security door immediately alerted the driver and passengers to discover and dispose in time. At the same time, it will follow the example of the rapid transit system and gradually set up public transport stations in a closed form.

Therefore, from the general situation, the bus station explosion-proof security inspection application features: First, accuracy, bus station security inspection products require a more rapid speed on the basis of a more accurate identification, while stability is strong. Security facilities at bus stations need to be integrated with the entire security system at the same time. The second is intelligence. At present, the investment in bus station applications in the security inspection not only includes the purchase of corresponding security inspection equipment, but also needs to increase the corresponding security personnel. . With the increase of detection methods and the increase in the degree of complexity, the requirements for the professional quality of security personnel have increased, and the cost of security has increased. Therefore, developing more intelligent inspection methods and improving the working efficiency of security personnel are also important directions for the development of security inspection equipment. Third, miniaturization, the bus station itself has a small area, many passengers, plus passengers to carry luggage. Small, so the requirements for explosion-proof security devices must be miniaturized.

At present, as a well-known security equipment manufacturer at home and abroad, Weishi Group has begun to develop small security products in response to the new security screening market demand. In the past three years, the small baggage goods machine, handheld ** detection Instruments and other products in the domestic market share of more than 50%. With the new market demand, Viagra shares are also looking for transformation and upgrading. At present, the company is making adjustments to technological innovation and product research and development in response to the new situation, especially for public transportation system products. Because public transportation and other places are densely populated and widely distributed, security inspections are both convenient and intelligent, and security inspections cannot affect public transportation. Convenience.

Fourth, establish a "pan-security" system

Experts believe that the safety of public transport depends solely on the supervision of public security agencies, traffic management and other government departments. Extensively calling on passengers to participate in the construction of a safe environment, as well as the suppression of non-safety behavior, can build a "pan-security" system for public transport.

In the Guangzhou bus arson case, the arson escaped from the car and exploded into the carriage. It took about half a minute. If the arsonist is ignited by a lead wire, then if a passenger cuts the lead in time within half a minute, it may be possible to avoid the tragedy. Some bus drivers believe that the safety of public transport needs to be maintained by the public. It is necessary not only to comply with the rules of not being able to bring flammable and explosive flammable dangerous goods onto the vehicle, but also to pay attention to the surrounding environment on the vehicle and to promptly notify the driver of any suspected dangerous goods. reflect. At the same time, strengthen safety education and raise safety awareness. Public security education should be legalized and normalized. It should be clearly defined that primary and secondary school students, including college students, receive public safety education for a fixed period each year. Through learning and practice, safety knowledge is converted into safety habits.

In addition, popularize escape techniques and improve self-rescue capabilities. In a random interview, the reporter found that many passengers were not aware of the correct use of safety devices such as fire extinguishers, safety hammers, and emergency valve doors. A related person of Guangzhou FAW Bus Co., Ltd. said that in many cities, there are 6 to 8 escape hammers installed on each bus, pick up a hammer and knock two or three times under any of the four corners of the glass window. It will be meshed and you can escape with your feet. "If you can't find this hammer, you can find everything that is sharp and strong. For example, men's belt buckle, especially the stilettos on the lady's feet, are all good tools."
