Technical Field

The invention relates to the technical field of vehicle security, in particular to a vehicle trailing alarm system.

Background

Along with the implementation of an automatic toll collection system and an Electronic Toll Collection (ETC) system, the number of toll station watchers is greatly reduced, vehicles are subjected to toll evasion at any time, losses are brought to countries, groups and companies, the vehicle toll evasion time period is mostly generated at night, although the toll station is provided with a perfect monitoring system, the toll evasion vehicles are found out from tens of thousands of vehicles, and the toll station is not different from a sea fishing needle. The following fee evasion utilizes the time delay characteristics of the vehicle detector and the ground induction coil to cheat in the acceptable range of the charging system, when the condition occurs, the charging system cannot accurately identify a following vehicle, the following vehicle and a previous vehicle are judged to be a transaction, the transaction is free of any abnormality, particularly, the following vehicle is mostly an outsourced vehicle, and difficulty is increased for inspection and entrance evidence obtaining. In light of the above circumstances, a simple and easy-to-use device for identifying fee evasion situations is urgently needed for the exit of the ETC on the highway.

Disclosure of Invention

According to the characteristics, the vehicle trailing alarm system comprises a vehicle detector, wherein the vehicle detector detects to acquire a sampling signal and a relay signal and transmits the relay signal to an automatic charging system;

the sampling signal synchronously triggers a delay relay, the excitation time of the signal is timed through the setting of a single chip microcomputer, if the excitation time does not exceed a preset value, the trigger is judged to be normal trigger, a calculator returns to zero, if the excitation signal exceeds the preset value, the single chip microcomputer of the delay relay judges the trigger to be abnormal transaction, the single chip microcomputer generates time sequence trigger, enters a call-back state, and transmits the signal of the state to a next-stage Internet of things module;

the Internet of things module is connected with the Internet and bound with a required client, and if the Internet of things module collects the time sequence trigger generated by the time delay relay, the time sequence trigger signal is converted into alarm quantity information and uploaded to an Internet of things server;

and after the information uploaded to the Internet of things server is loaded with the elements of time information, equipment information and position information, the information is forwarded to the client.

The generated alarm information is silently uploaded to a network and forwarded to management and inspection personnel, so that manual resolution and evidence obtaining are facilitated.

The direct current relay is a sampling core, has strong anti-interference capability, simple and convenient installation and accurate signal transmission, does not change any charging facility, and transmits data information through a router and the Internet. The concealment is high, and the traffic order and the driving safety are not influenced.

Further, the client is a receiving device such as a PC and a mobile phone.

Furthermore, the alarm is powered by direct current 5V or 12V, the overall power consumption is reduced, a vehicle detector adopts a relay mode in an acquisition mode, the anti-interference capability is high, the signal relay is accurate, and the delay is less than 0.2 millisecond.

By adopting the technical scheme, the method has the following technical effects:

(1) the invention has the advantages of low equipment cost, simple installation, good concealment, silent triggering, no influence on passers-by, no change of charging system equipment, support of a router network and large-scale and intensive use.

(2) The toll lane provided with the alarm has the same appearance, function, use and other aspects as those of the toll lane without the alarm. And the alarm is sent out in a silent mode, so that the charging and passing cannot be influenced.

(3) The suspected following fee evasion vehicle meets the conditions in the passing process and triggers an alarm, and the alarm information is transmitted to the cloud server through the Internet of things.

(4) The internet of things server stores alarm information generated in one week and arranges the alarm information according to time sequence. When the alarm amount occurs, the information is sent to the APP, the WeChat client and the PC client through the network in real time, so that the staff can find the information in time.
