While the oil sales enterprises on the theft of oil behavior repeatedly crack down, but repeatedly prohibited, there are reports of certain provinces and cities in the enterprise to steal and change the oil events. Stealing oil for oil caused by three hazards: First, oil theft caused by oil loss, the cumulative number of shocking; Second, oil for oil caused by the gas station oil quality is not qualified, triggering social events, serious damage to the oil company's brand image; Third, the process of stealing and changing the oil may cause an explosion, endangering social security.
The use of human means of defense to prevent theft and oil change work is difficult, tanker truck drivers to steal oil more than one way, the distribution area of the large area on the way can not be monitored, and some of the depot station and the driver and passenger internal and external collusion, resulting in the management of the Department of fatigue, in the past, with the ambush at night raids to arrest the wrongdoers, not only inefficient, and there is a personal danger.
In the past, the commonly used technical defense is to play the seal to control the loading and unloading of oil port, but there are many drawbacks, one is easy to be cracked by the lawless elements, the seal is virtually non-existent; two is the oil depot to play the process of the seal time-consuming and exhausting, to record the number of each seal and the location of the seal to the gas station to be verified one by one and fill out the written records, the workload is very large.
Beijing Wanjiaxin believes that a good set of electronic sealing system should not only manage the oil theft at both ends of the oil depot and gas station, but also manage the transportation process. Illegal parking, abnormal lock conditions, abnormal circuit conditions, etc. during transportation will be alarmed in time.
The control logic of this system is very strict. Three conditions need to be met in order to open the lock: the card is valid, the swipe location must be within the effective range of the oil depot station, and must be consistent with the delivery order. The communication transmission process also requires a lot of encryption.
The system should be very simple to operate, oil depots and gas stations only need to be equipped with a card, the vehicle to the station can be opened by swiping the card. There is no need for any auxiliary equipment to be installed at the fuel depot and station, making it easy to implement and promote.
The system should have strong flexibility and emergency response capabilities. Oil companies often face the social oil station or external units distribution business, temporary business is more and there is uncertainty, and the gas station distribution business also exists in the case of temporary change orders, so the system is required to have the flexibility to provide a variety of ways to Shi unblocked. Oil companies often distribute to remote areas, walking through mountains and tunnels, encountering network communication interruptions, card loss and damage, or vehicle traffic accidents, and sometimes server crashes, the system can be remotely or password unblocking, timely processing.
The system requires a very stable product. The product design requires multi-disciplinary knowledge of software, electronics, machinery, safety and explosion-proof and materials. First of all, its components require the use of automotive-grade standards, much higher than industrial-grade and commercial-grade standards, second only to military-grade; secondly, because it is installed in the car body outside the wind and rain, must give full consideration to anti-vibration waterproof and dustproof design, as well as high and low temperature design; at the same time, explosion-proof design requires that the product's mechanical dimensions, the alignment of the drawing must be strictly in line with the specifications; in addition, this device is very special that it will be subjected to constant man-made In addition, the equipment is very special that it will be constantly subject to human destruction and attack, the driver will take the signal interference, power outages, violent demolition, high temperature destruction and other means, requiring strong durability of the product.
The system should be able to guard against the details of the driver to steal oil in the details of the action, the integrity of the mechanical design of the hardware and equipment and mechanical manufacturing precision requirements are very high. Some manufacturers program claims to be able to control the tanker truck oil port, but after in-depth analysis of its mechanical and technical principles, you can find that the gap is very large, the lack of detail considerations. For example, some of the equipment after the card, the default equipment has been closed, and no detection device feedback information, the system feedback may be false information; some equipment designed to detect the lock status, but did not do in-depth detection of the valve status, the feedback up to the information is incomplete. From the actual operation of the driver with the help of this loophole, not in place when closing the valve, leaving a thin seam, even if the card successfully locked, the actual still stealing oil.
A good system is one that evolves like a living thing. Although the system controls the loading and unloading of oil, to solve the main problem, but also can not rest on their laurels, taking into account the endless means of criminals, the system should be able to do vehicle behavior analysis through big data mining, from the vehicle on the way to the parking time, location and number of times as well as power outages and disconnections of the frequency of the data to find out the abnormal behavior of the vehicle, on-site raids. Continuously form a high-pressure deterrent.
