Petroleum and petrochemical industry is a high-temperature, high-pressure, flammable, explosive and toxic dangerous industry with complex production processes and large-scale equipment. Especially in some liquefaction tank areas. For a long time, patrols have been using a traditional mechanical patrol system. The route, time, frequency, and density of patrols are all unreasonable. Repeated waste often gets twice the result with half the effort. In addition, some patrol personnel are not strong in their sense of responsibility, and there are passive attitudes of sabotage, no effort at work, and “being a monk for a day, hitting the clock for a day”. There is a lot of blindness and passivity. At the same time, due to the lack of effective supervision, the implementation of the measures cannot be guaranteed, the patrol effect is not obvious, and the effect is not large. The various patrol measures have not been truly implemented, resulting in the randomness and blindness of patrols. A lot of manpower and material resources have been invested, but they have failed to achieve the desired results.
How to make patrol and inspection work more scientific, standardized, and institutionalized, and truly achieve the goal of strict and effective control of the society, must be innovative and boldly reform the existing working mechanisms and service methods. The most important thing is We must rely on modern scientific and technological means and the introduction of scientific supervision mechanisms. Only when the patrol inspection work is established on a modern scientific and technological platform and placed under scientific and effective supervision, can it operate efficiently and give full play to its best effectiveness.
After investigation and full demonstration, the “electronic patrol” system can effectively supervise and manage the patrol situation, can accurately record the patrol time, frequency and line of the patrol personnel, and has no wiring, flexible use, simple operation and strong pertinence. The characteristics are of great reference value for supervision, regulation and improvement of patrol work. At the same time, the “electronic patrol” system can rely on computer information networks to share resources, with strong vitality and broad development space. It is a favorable carrier for strengthening urban patrol prevention in the new era.
1. The basic principle of the patrol inspection system
Install the information button in the place where patrol inspection is required, and at the same time correspond the code of the information button to the location number in the system software, and perform classification processing. When the patrol inspector inspects, use the inspector to read the information of the information button on the equipment. After the inspection is completed, the data is sent to the computer through the communicator. The computer checks the data and counts the inspection time, abnormal conditions, etc., and The situation of each point can be displayed graphically, clearly and intuitively.
Design features of inspection management system
(1) Since the petroleum and petrochemical system is a dangerous industry that is flammable, explosive and toxic, the inspection products must be inductive, so as to effectively prevent the loss of checkpoints and man-made damage, so as to avoid new hidden safety hazards. The design of the inspection device in the system is beautiful and practical, and the operation is convenient. The large capacity can store 28,000 pieces of data (including the number of the read information button and the time when it is read), and the data will not be lost due to power failure (Flash storage), and can be stored for more than ten years. All circuits adopt the world’s leading new design, which meets the requirements of a revolutionary low power consumption system. The relevant machine automatically detects the card function, and the detection current (working current) is less than 0.2mAh. At the same time, it uses a rechargeable lithium battery with a capacity of 900mAh, which can work for one month on a single charge.
(2) The communicator is divided into a special type and a remote type. The special type has an RS232 serial port, which can be directly connected to a computer and has a built-in energy-saving chip. The remote type has a built-in high-performance microprocessor, built-in MODEM, large-capacity memory, fully automatic dialing circuit, and has a remote verification function. It can automatically upload the inspection status of each grass-roots unit through a telephone Modem or a local area network, which is convenient for leaders at all levels to check. At the same time, it is convenient for remote service.
(3) The data is highly secure. Both the data and the program are strictly encrypted and cannot be changed. The patrol, communicator and computer management system in the system fully embodies the design idea of ensuring high reliability of data reading, transmission and storage, and will not miss or misread, and will not lose data, especially in various In harsh environments, such as vibration, water, and power outages, data will not be lost.
(4) Blue Card innovative products are not only technologically advanced, but also software and hardware products have been used by users at home and abroad for a long time, and the quality is stable, mature and reliable. It has been widely used in petroleum, telecommunications, public transportation, public security, railways, coal mines, postal, security and other industries. The users are very satisfied, and the sales volume ranks first in China.
