China Security Exhibition Reuters is the production of safe industrial processes has been extremely important part of a good monitoring system can effectively carry out production supervision, to avoid possible security problems in the production process. However, most of the current industrial production monitoring is simply video surveillance. It is entirely due to human eyes staring at the display screen and human negligence often occurs. Therefore, intelligent security prosecutors came into being!
Intelligent security applied to industrial production
The security system integration is also only for the simple integration of the security system. It generally includes only video, access control, and intrusion prevention alarms. Some alarm information and abnormal times in the production process do not interact with the security system. Therefore, the security system is usually operated and managed independently by the security department in the factory, and it is difficult to integrate it into the industrial production safety management system. In this way, a factory must use two independent systems of the security system and the production safety management system. In the event of an emergency, due to the relative independence of the two systems, inefficiency arises during processing, causing some unnecessary losses. In fact, the security system can be comprehensively applied to the industrial production safety management field.
In the special occasions of the petroleum and petrochemical industry, the demand for theft prevention and visualization is relatively low, and its safety problems mainly stem from special events in the production process. Industrial safety production monitoring is supervised by the production dispatch department, and is usually independent from the safety and security department. When an accident occurs, it often requires manual collection of other relevant information. If the efficiency of this process is low, the best opportunity to deal with the problem is likely to be lost. .
Therefore, whether it is possible to combine the safety factors in industrial production with traditional safety precautions and complete the intelligent decision-making assistance for rapid industrial safety is a key indicator of whether the petroleum and petrochemical industry safety management system is qualified or not. Industrial security intelligent system solutions must combine traditional security and production safety management systems into a comprehensive management system. Through multiple theoretical arguments and practical emergency drills, it is confirmed that it is a complete set of intelligent security precautions. system.
Take the intelligent security of the petroleum industry as an example
The following brief introduction to the successful implementation of a large-scale petrochemical plant in a state-owned company will provide a brief introduction to the solution for the intelligent security system of the petrochemical industry. (Case background: A natural gas purification plant with a total investment of 14 billion yuan was invested in a gas field. The project covers an area of ​​3,400 mu. The plant mainly purifies high-sulfur natural gas and will produce 20 billion cubic meters of natural gas per year after completion.
Security Protection Subsystem
The security subsystem includes: video surveillance system, perimeter alarm system, access control system, fire alarm system, toxic and harmful gas concentration alarm system, safety escape system, manual alarm system, telephone alarm system, public broadcasting system and security dispatch center plane Display screens and two dispatch command centers (one of them is a sub-command center, mainly used for video surveillance).
Video surveillance system (integrated into industrial TV monitoring system
Using the analog matrix system and DVR storage, the camera mainly monitors the perimeter of the plant, the torch, the roads in the plant area and the production device area. The cameras and auxiliary equipment installed in the important parts are all treated with explosion-proof. The perimeter monitor uses high-performance fast balls. Type camera. Because the plant area is large and the straight-line distance is far, the distribution is similar to the two sub-factories, so the plant has set up two monitoring centers, one of which is the main monitoring center, responsible for the whole plant safety dispatch, and one is the sub-supervisory control center, mainly used as the sulfur warehouse packaging. And transportation monitoring. Its main equipment distribution includes (Figure 1):
1. The perimeter video surveillance of the perimeter wall is used to visualize the surrounding environment and prevent illegal entry. When the perimeter alarm occurs, it can be quickly switched to the alarm location and use the nitrogen speed dome ball.
2. Video surveillance in the production area is used to visualize the management of the production device area, and the abnormality of the equipment and personnel monitoring at the production site are detected in time; all explosion-proof cameras are used;
3, torch monitoring, used to monitor the flame produced by the torch combustion, and found abnormal combustion exhaust gas at the same time, requiring that the white balance automatically adjust accurately;
4. Furnace monitoring, which is used to monitor the interior of the furnace and detect the abnormality of the furnace in time, using a dedicated camera for the furnace;
5. Factory site monitoring, which is used to monitor the non-production areas in the plant, including personnel in the factory, vehicle distribution and movement monitoring, and range monitoring, etc., using ordinary cameras, pan-tilt zoom cameras, and 360-degree panoramic cameras respectively;
6, the main dispatch center and production center, security room distribution monitor and matrix keyboard, and assign the appropriate authority, authorized designated personnel position responsible for monitoring.
Perimeter alarm system
Due to the long straight line distance between the perimeter and the required monitoring distance of nearly 10 kilometers, plus the site is located in the misty mountainous area, based on the comprehensive infrared radiation and other model characteristics, the plant finally chooses the vibration cable alarm system, which is subject to Weather and other natural factors have little effect, low false alarm rate, easy construction, and high safety factor. The main managers of perimeter monitoring are security personnel and emergency rescue centers.
Access Control System
The access control system is mainly used for personnel access control and emergency escape systems at the factory gates (as shown in Figure 3). Normally, the administrators are responsible for security and administrative management. In emergencies, they can be directly controlled by the security dispatch center. In addition to the use of three-roll gates, each entrance has a camera for real-time monitoring. When an error occurs, the corresponding video screen will automatically switch to the monitor where the manager is located.
Fire alarm subsystem
Fire alarm system is large. Due to the peculiarities of the petrochemical industry, the number of on-site fire alarm detectors and emergency buttons reached 1,000.
Gas detection system toxic and harmful gas concentration alarm
The toxic and harmful gas concentration alarm is the alarm information generated during the production process, and the number of detection points is also thousands. When the harmful gas concentration in the monitoring area exceeds the preset value, a high-level alarm will be generated. The preset value, including the alarm concentration and the high-risk concentration alarm, needs to be distinguished. Usually the user is a production dispatch center and uploads alarm information at any time (as shown in Figure 4).
Emergency response subsystem manual alarm system and telephone alarm
Taking into account the possible blind spots of fire alarms and gas concentration detection, the corresponding manual alarm buttons and program-controlled telephones are set in the production area in accordance with the regional location distribution. They are used for manual alarms. When the buttons are pressed or the programmed telephone is taken off, the system will Automatically generate alarm signal. The system administrator is a security dispatch center.
Public address system
The whole plant has set up a public broadcasting system, and the monitoring center can start public broadcasting in the whole plant or the corresponding area according to the actual situation, and conduct emergency evacuation and notification. The operation and management of this system is the responsibility of the security dispatch center.
Electronic sand table system
Gathers industrial safety status and alarm information such as gas detection, fire-fighting, channel control, perimeter prevention, etc. obtained by sensors of the whole plant, and turns on corresponding indicators on the LED screen through a highly reliable drive circuit to drive sound and light alarms. Synchronized sound indicates alarm information.
Emergency escape system
In order to facilitate safety management, the entire plant area is in a relatively closed safety environment. All safety doors are closed, and the main entrances and exits are restricted to go in and out freely. When the urgency reaches the corresponding level, the emergency escape system is started. All the escape doors can be opened automatically and manually. Security alert. Since the high-risk situation that may occur in the plant is the spread of toxic gas, the monitoring center will use public broadcasting to guide the escape route in combination with the alarm geography and on-site air flow conditions. The manager is the security dispatch center (shown in Figure 5).
Safety Production Assistance Decision Platform
The safety production aid decision platform is a software platform that comprehensively controls the above subsystems (see Figure 6). Its functions include receiving various information from the subsystems, analyzing various information in an integrated manner, and intelligently sending each subsystem to each subsystem. The instructions further obtain various information data and provide decision-makers with final instructions. In the absence of human decision makers, they will automatically complete various decisions and send decision-making instructions to various subsystems. Taking into account the various types of false positives that may occur in various subsystems, the integrated control platform must be quite intelligent rather than an ordinary automation platform. Because in addition to traditional security, it also includes other systems, and the entire system is based on a variety of alarms (as shown in Figure 7), which is no longer a traditional security management platform. The security event implementation logic of the system includes:
1, low-level security incidents, including equipment failures, equipment false alarms, common illegal personnel entry:
The system will automatically deploy the video to the relevant personnel and issue voice prompts. The main dispatch center safety escape platform will prompt the dispatch center personnel with the characteristic light signal in the corresponding geographic location. After the event is over, the system will automatically return to normal 2, moderate security incidents, and nightly illegal personnel. Into, toxic gas alarms, fire alarms, etc.:
The system automatically completes the video deployment. The main dispatch center safety escape platform will have an emergency prompt. The system will make a low-level response according to the security incident. The local emergency escape system will be activated to inform the relevant management staff and whether to promptly execute the preplan operation and whether to notify the emergency rescue center.
3. High-risk security incidents, serious leakage of toxic and harmful gases, and large-scale fires, etc.:
The system automatically executes related actions, opens all public radio alarms, starts the escape system, and automatically informs the emergency rescue center.
Intelligent security applied to industrial production
The security system integration is also only for the simple integration of the security system. It generally includes only video, access control, and intrusion prevention alarms. Some alarm information and abnormal times in the production process do not interact with the security system. Therefore, the security system is usually operated and managed independently by the security department in the factory, and it is difficult to integrate it into the industrial production safety management system.
