Embodiment Construction

[0010] The working principle of the existing vehicle inspection equipment (such as the inspector disclosed in the invention patent CN103640516A) is as follows: figure 1 As shown, during the inspection, the inspection devices A and B respectively control the wireless transceiver module to transmit wireless inspection signals a and b to surrounding vehicles (not shown) through the main processor. The method for avoiding mutual interference of vehicle inspection devices provided by the present invention is to stipulate in the built-in program of the inspection device that when the inspection device A receives the wireless inspection signal b sent by the inspection device B, under the control of the built-in program of its main processor, the wireless The transceiver module stops transmitting the wireless inspection signal a, and maintains the receiving state for 1 second; if the wireless inspection signal b sent by the inspection device B is not received after 1 second, the main p...

Abstract

The invention discloses a method for preventing vehicle inspection devices from interfering with one another. The method includes the steps that according to the stipulation in built-in programs of the vehicle inspection devices, if one inspection device in an inspection work state receives inspection signals sent out by other inspection devices, the inspection device immediately stops transmitting inspection signals and is kept in a receiving state for a period of time, and then if not receiving the other inspection signals, the inspection device recovers the original inspection work state; in the period of the receiving state, the inspection device can still receive vehicle related information transmitted by a wireless terminal on a vehicle. It can be avoided that normal inspection work is affected by mutual interference among the inspection devices just by setting the programs, and the method has the advantages of being simple, easy to implement and good in effect.

Description

technical field [0001] The invention belongs to motor vehicle inspection technology, in particular to a method for avoiding mutual interference of vehicle inspection equipment. Background technique [0002] In order to achieve effective management of vehicles, there is a method to install a wireless terminal on the vehicle. The wireless terminal contains a memory that can save vehicle-related information. The vehicle management department uses the vehicle inspection equipment to communicate wirelessly with the wireless terminal of the vehicle. Check the condition of the vehicle. If the wireless terminal receives the wireless inspection signal sent by the vehicle inspection equipment, the wireless terminal will wirelessly transmit the stored vehicle-related information, which will be received and identified by the inspection equipment. The inspection equipment includes a main processor and a wireless transceiver module. If the device adopts the automatic inspection mode of ...
