Abstract

The invention provides a portable radar tester comprising a power supply, a microwave module, an interface conversion module, a fixed bracket, a handheld end and a box body. The power supply unit provides working power for a measured speed measuring radar device. The microwave module is connected with the handheld end and is integrated into the fixed bracket. The handheld end is connected with theinterface conversion module. The interface conversion module is connected with the interface of the measured speed measuring radar. The handheld end sends a command through installed upper computer software to control the microwave module to transmit a signal with a set characteristic to the speed measuring radar; the interface conversion module receives information outputted by the speed measuring radar; the received information is compared with the information sent by the control to carry out determination. The portable radar tester has the following beneficial effects: with the portable radar tester, out-of-factory detection, in-storage house detection of the radar spare parts, detection after radar installation, and the field fault radar anomaly detection and the like can be realized;and the main functions and performances of the speed measuring radar device can be tested.

Description

technical field [0001] The invention relates to the application field of railway signal equipment detection, in particular to a portable speed measuring radar tester and a detection method. technical background [0002] The speed measuring radar is a speed measuring sensor device specially developed for railway vehicles. The working voltage is 15V ~ 150V. It uses the Doppler effect principle, and the working frequency band is in the K band of 24GHz. It measures the running speed and driving direction of the vehicle through a non-contact method. And provide information such as speed, status, direction and travel distance to the train control on-board equipment through the RS485 interface, and the on-board equipment completes relevant functions such as vehicle control and position correction based on the information obtained from the speed measuring radar. Therefore, it is particularly important to identify and diagnose the abnormality of the speed measuring radar equipment. A...
