Embodiment approach

[0030] Implementation method: Determine the direction (uplink or downlink) that the radar module needs to detect moving targets according to the area protected by the on-site operation, and align the radar module 1 and radar module 2 with the uplink and downlink detection directions respectively; turn on the power to start the radar The module emits radar waves to detect moving targets, obtains its information and displays it; the speed and distance information of the moving target exceeds the alarm threshold set by the system, and the system gives an audible and visual alarm; on-site operators evacuate to a safe area.

[0031] This example implements V-shaped skylights or vertical skylights suitable for railway site construction operations. During the site operations, a set of radar module 1 and radar module 2 of the system are respectively aligned with the direction of uplink or downlink vehicles. The radar module 1 adopts 16GHz radar, radar module 2 adopts 24GHz radar, micro...

Abstract

The invention discloses a radar-based bidirectional safeguard system and a radar-based bidirectional safeguard method for railway field operation. The radar-based bidirectional safeguard system comprises a radar module 1, a radar module 2, a high-velocity electronic diverter switch, a microprocessor, a liquid crystal display, a rotary switch, a relay, an acousto-optic alarm, a power supply and a voltage reduction module. The radar module 1 and the radar module 2 are used for respectively detecting moving targets within 1.5km on an up-going side and a down-going side of an operation point, and detection data are transmitted to the microprocessor through the high-velocity electronic diverter switch by the aid of an RS232 interface; the microprocessor is used for processing and analyzing the detection data from the radar module 1 and the radar module 2, displaying moving target information on the liquid crystal display and comparing the moving target information with a set initial threshold value. By the aid of the rotary switch, an alarming threshold value is set when equipment is started, and the moving target information can be inquired in a non-alarming state during operation of the equipment.

Description

technical field [0001] The invention relates to the fields of radar detection technology and information processing, in particular to a radar-based two-way 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 strate...
