Portable vehicle detector

Abstract

The invention discloses a portable vehicle detector, which comprises an anisotropic magnetoresistive vehicle detector, a charging and wired control data transmission interface and a hand-held wireless transmission and receiving control device, the anisotropic magnetoresistive vehicle detector is responsible for acquiring vehicle information data, the charging and wired control data transmission interface is used for charging the anisotropic magnetoresistive vehicle detector and debugging and upgrading internal software, and the hand-held wireless transmission and receiving control device is responsible for wirelessly controlling the working state of the anisotropic magnetoresistive vehicle detector and wirelessly extracting memory area data. The portable vehicle detector is portable, can be repetitively used and adapted to different environments and weathers, can carry out detection without requiring additional wiring and pavement destruction and detect various needed traffic parameters, is convenient to mount and maintain, and has high safety performance, high stability, high detection precision and little affection on the running of vehicles.

Description

technical field [0001] The invention relates to vehicle detector technology, in particular to a portable vehicle detector. Background technique [0002] With the development of the economy, the number of domestic motor vehicles has increased rapidly, which has brought severe tests to urban traffic. In order to make urban traffic smooth and comfortable, the collection of traffic information becomes a key link. The traffic information detector is to use the traffic information collection technology to monitor the traffic conditions on the road surface in real time, and grasp the dynamic changes of traffic flow from the macro and micro in time. Among the various good and bad traffic information detectors that have appeared, the portability and reusability of the detector has increasingly become a requirement. [0003] At present, the most widely used vehicle detectors in China include toroidal coil detectors and geomagnetic detectors. Although the coil detector is the most w...

AI Technical Summary

Problems solved by technology

Although the coil detector is the most widely used, it has inherent and fatal shortcomings: First, the coil detector can only perform fixed detection, once installed, it is difficult to move and it is difficult to reuse

Second, the coil must be slotted on the driveway. In actual use, due to the soft foundation problems of highways in many coastal areas and the high rate of coil damage during maintenance, the maintenance work is complicated.

3. Repair or installation needs to interrupt traffic, causing inconvenience for citizens to travel

Fourth, although the vehicle inspection data is accurate, it is relatively not intuitive enough. Sometimes the message has lagged behind when the vehicle detector sends out a warning sound, or the monitoring personnel are worried that the data is wrong and hesitate, which leads to delays or mistakes to send further instructions to the field equipment

In addition, there are geomagnetic detectors such as the disclosed invention patent: a wireless geomagnetic vehicle detection system, application number: 200710036504.9, which uses geomagnetic detection technology. When installing, it is necessary to drill cylindrical holes in the driveway, which will damage the road conditions. , and this detector is also a fixed detection after being sealed, it cannot be moved or reused, and cannot meet the needs of portability and reusability
