Abstract

The invention discloses a radar-based railway on-situ operation safety protection system and method. The system consists of a radar module, a microprocessor, a liquid crystal display screen, a knob switch, a relay, an acoustic-optic alarm, a power supply and a voltage dropping module, wherein the radar module is used for detecting a movable target within 1.5km at a protection side, and measurement data are transmitted to the microprocessor via an RS232 interface; the microprocessor processes and analyzes the measurement data, the information about the movable target is displayed on the liquid crystal display screen, the information about the movable target is successively compared with an initial set threshold value, if the information exceeds the threshold value, the relay is triggered to drive the acoustic-optic alarm to issue an alarm, and the operation personnel is reminded of withdrawing to a safety area; and by virtue of the knob switch, the alarming threshold value is set when the device is started, and the information about the movable target also can be inquired in the operation process of the device and when the device does not stay at an alarm state.

Description

technical field [0001] The invention relates to the fields of radar detection technology and information processing, in particular to a radar-based safety protection system and method for railway field operations. Background technique [0002] Railway on-site construction and maintenance of operating equipment are important conditions to ensure the normal operation of the railway. Railway on-site construction and maintenance operations require that the impact on railway transportation be minimized under the premise of ensuring safety. Therefore, it is important to ensure the safety of railway on-site construction operations. practical significance. [0003] At present, the protection of railway on-site operations is mainly based on "manual three-point protection" and system constraints, and there is a lack of practical auxiliary devices. There is a greater threat to the personal safety of operators, equipment and railway traffic. On-site operation protection strategies and...
