Embodiment 1

[0088] A dangerous rockfall alarm system, such as figure 1As shown, the dangerous rockfall alarm system consists of a detection network I, a detection unit II, a signal processing and operation recording unit III, a detection alarm unit IV, a manual control unit V, an on-site sound and light alarm unit VI and a power supply module VII;

[0089] The detection unit II includes a sensor group 21 and a monitoring and processing circuit. Each sensor of the sensor group 21 is installed on the column of the detection net I to provide timely information for the signal processing and operation recording unit. signal of;

[0090] The signal processing and operation recording unit III monitors the sensor signals on the detection network, and controls the activation of the on-site sound and light alarm unit VI and the trigger detection alarm unit IV after monitoring the signal that the detection network is hit by dangerous rocks, slope collapse or debris flow, And record all operations a...

Embodiment 2

[0126] A method for alarming dangerous rockfall, which uses the dangerous rockfall alarm system described in Embodiment 1, and reasonably sets n detection networks I1, I2, I3,... …In (cf. Figure 9 , Figure 10 ), install the m detection sensors 211, 212 ... 21m-1, 21m of the sensor group 21 of the detection alarm unit II on the column 11 of each detection network, and the system will monitor the status of the detection network in real time. , Slope collapse or debris flow, impact on the detection network or cause displacement, resulting in serious tilting of the detection network column, the detection unit II sends a signal, and the signal processing and operation recording unit III receives the detection network is dangerous rockfall, slope collapse or Immediately start the on-site sound and light alarm equipment Ⅵ after the debris flow hits the signal, sound the alarm horn and flash the alarm lights, and notify the on-site guards to start the emergency treatment procedure;...

Abstract

The invention discloses a dangerous rock falling stone alarm system and a method for dangerous rock falling stone alarm. The system comprises a detection net, a detection unit, a signal processing and operation recording unit, a detection alarm unit, a manual control unit, a field acousto-optic alarm unit and a power supply module, wherein the five units are connected in a wired mode; the detection unit comprises a sensor set and a monitoring processing circuit, each sensor of the sensor set is arranged on an upright post of the detection net, and the sensors provide signals that the detection net is struck by falling stones for the signal processing and operation recording unit in time; the signal processing and operation recording unit monitors the sensor signals on the detection net, controlling and starting the detection alarm unit and the field acousto-optic alarm unit after the signals that the detection net is struck by the dangerous stones are detected, and recording all operations and disaster information; and the manual control unit can manually control and start the field acousto-optic alarm unit. The alarm system and the alarm method do not depend on the services provided by a third party, and have high alarm reliability and instantaneity.

Description

technical field [0001] The invention relates to a detection and alarm technology, in particular to a dangerous rockfall alarm system and a method for alarm detection of dangerous rockfall. Background technique [0002] Slope collapse and dangerous rockfall are common unfavorable geological phenomena in mountainous areas; most of the railway lines in Southwest China are located in mountainous areas, and slope collapse and dangerous rockfall seriously threaten driving safety; only within the jurisdiction of Nanning Railway Bureau, along the railway There are more than 500 flood control points for slope collapse and dangerous rockfall, including more than 250 AA-level flood control points. At present, the method adopted by the public works department of Nanning Railway Bureau is to install active nets Or passive network, most of the flood control points are arranged for special caregivers to guard 24 hours a day and night, once a disaster occurs, it will immediately call the po...
