How to solve the problem

How to solve the problem of patting randomly and missing patting and not lifting the lever

Intelligent parking system, the brake sometimes disorderly patting, miss patting, sometimes also will hit the vehicle, causing unnecessary disputes, especially rainy weather this phenomenon is serious. Generally, the construction company will consider the problem of the sensor in many cases, but sometimes the real reason is the problem of the ground sensing wire, which is caused by the damage of the wire or the substandard insulation resistance.

How do you solve this problem? Let’s talk more about it.

According to data from the China association of automobile dealers, China’s car ownership has exceeded 194 million in 2017, and there are 35 cities with more than 1 million cars nationwide. Parking is a vital requirement of automobile life, and smart parking is an important part of smart cities. Intelligent license plate recognition billing system, only needs two to three seconds to complete the complex calculation and payment, and eliminate the payment dispute. In commercial parking lots with large parking flow and serious exit congestion, exit traffic efficiency can be greatly improved, cost loss can be reduced, and labor cost can be saved. Meanwhile, from the perspective of creative value and parking reservation service, the closed-loop process of parking reservation, arrival, appearance and related services can be completed.

Ground sense coil just intelligent recognition system of license plate, a small accessory products, but it and the brake is the same, the brake at work at the same time, it also in work, non-stop work 24 hours a day, the stability of a direct impact on the normal operation of the license plate recognition system, especially the coil wire, buried the most problematic, must choose high strength, anti-aging, high and low temperature resistance, still have to oil resistance, so when installing intelligent license plate recognition system must be strict requirements, nip in the bud.

The ground sensor commonly used in the market usually has the following conditions:

1. The insulation resistance is low and will lose its insulation when soaked for a long time in damp underground environment. This is the main reason for bad shooting.

2. The insulation thickness of conventional products is relatively thin, and the construction site environment is relatively harsh. It is particularly easy to wear out when laid in the open air. This is also an important reason for improper shooting.

Therefore, the selection and use of ground sensor coil in intelligent parking system plays an important role in the safety and accurate operation of the whole system. Improper selection of ground sensor or improper performance of wire will significantly reduce the inductance of the coil, resulting in reduced detection sensitivity.

To sum up, we must pay attention to the following matters in the selection and use of ground induction coil:

1. Standard of wire selection: generally 0.5mm ^ 2 ~1mm ^ 2 specification is used, the most commonly used specification is 0.75mm ^ 2 tin copper wire, teflon resistant insulation wire

2. The wire should be acid-resistant, corrosion-resistant, wear-resistant and durable, and teflon wire can meet such performance requirements

3. When wiring the coil, clear the small stones in the line slot, so as to avoid abnormal work caused by broken or broken skin of the coil line caused by rolling vehicles back and forth

4. Generally, the detection coil is rectangular, and the ground is cut into 45° chamfering at the four corners of rectangular or rectangular. When installing, when the line passes through the right Angle, it should be slow and careful, so as to avoid the wires being cut or cut

5. Wires should also be able to withstand high and low temperatures. Considering that outdoor temperature is affected by seasons, the temperature resistance range of teflon materials can reach -80℃ to 200 ℃ in the extremely hot and cold weather in summer and winter

6. There are many kinds of teflon wire on the market at present, you must choose anti-cracking, and acid and alkali resistance can be good varieties. 

Shanghai shenyuan high temperature line co., ltd. has more than ten years of experience in the development and production of ground sensor coil products, master the core technology of high temperature line production, specially developed for buried ground sensor coil lines, and cooperated with a number of intelligent parking system brand enterprises, which has won the praise of customers and high recognition of customers. Successfully overcome the technical problems of damage and insulation resistance.
