Abstract
The utility model discloses a foreign body intrusion detection apparatus, which comprises two monitor units arranged at an interval, wherein each monitor unit consists of a modulation circuit, a demodulation circuit, a tilt sensor circuit and a CPU chip; the output terminal of the modulation circuit in each monitor unit is connected with the input terminal of the demodulation circuit in the corresponding monitor unit; the output terminals of the tilt sensor circuit and the demodulation circuit in each monitor unit are respectively electrically connected with the input interface of the CPU chip in the unit; and the output terminal terminals of the CPU chips in the two monitor units are communicated with an upper warning computer through a communication bus. The foreign body intrusion detection apparatus has the advantage that the apparatus can real-timely detect the safety state of a railway transportation line in a specific area according to the attitude of the foreign body intrusion detection and the state of a monitor network. Meanwhile, the foreign body intrusion detection apparatus has simple and convenient implementation and higher practical value, and can send alarms of different levels by setting the alarm value.
Description
Technical field
The utility model relates to the railway anti-disaster safety monitoring system, especially relates to the foreign body intrusion check implement.
Background technology
The railway anti-disaster safety monitoring system is one of important foundation facility that guarantees the railway traffic safety operation.Mainly be that bursts such as the disaster that jeopardizes safety of railway traffic and foreign body intrusion harm is monitored, and provide after treatment disaster early-warning information, speed-limiting messages or stoppage in transit information etc., for traffic dispatch center's operational plan adjustment, assign driving control, rescue, maintenance etc. plan for emergency handling and foundation be provided, further improve railway traffic safety and efficiency of operation.Therefore, the accurate monitoring to disaster information is the basis of disaster prevention system.
The utility model content
The utility model purpose is to provide a kind of simple and practical foreign body intrusion check implement.
For achieving the above object, the utility model can be taked following technical proposals:
Foreign body intrusion check implement described in the utility model, it comprises two monitoring means that are provided with at interval; Described each monitoring means constitutes by modulation circuit, demodulator circuit, obliquity sensor circuit and cpu chip; Modulation circuit mouth in two monitoring means is electrically connected with demodulator circuit input end in another monitoring means by lead respectively; Obliquity sensor reconciliation circuit demodulation circuit mouth in each monitoring means is electrically connected with cpu chip input interface in this unit respectively; Cpu chip mouth in two monitoring means realizes that by communication bus and upper early warning main frame communication is connected.
Connect the net structure of two leads of described modulation circuit and demodulator circuit for braiding.
The utility model advantage is to be disposed on two integrated monitor unit of being made up of a hectare angle sensing circuit, modulation circuit, demodulator circuit, cpu chip in the equipment; And two leads that will connect described modulation circuit and demodulator circuit are arranged to net structure to constitute monitoring net.Therefore, when equipment is subjected to external force to cause monitoring net to score a goal, send information by modulation circuit, demodulator circuit receives information, by CPU these information of monitoring in real time is uploaded to the forewarn system of taking precautions against natural calamities and reports to the police; Or when equipment is subjected to external force run-off the straight or deformation to cause the obliquity sensor angle to change, by CPU these information of monitoring in real time is uploaded to the forewarn system of taking precautions against natural calamities and reports to the police.Thereby realize safe condition according to foreign matter encroachment line equipment attitude and monitoring net status real time monitor specific region railway supplyline.Simultaneously, the utility model implements simple and convenient, the practical value height; And can provide the warning of different stage by the setting of alarming value, and topple over as equipment, provide three grades of warnings; Monitoring net is scored a goal, and provides secondary and reports to the police; Equipment is toppled over and monitoring net is scored a goal, and provides one-level warning etc.
Description of drawings
Fig. 1 is a schematic block circuit diagram of the present utility model.
Fig. 2 is monitoring means schematic circuit diagram among Fig. 1.
The specific embodiment
As shown in the figure, foreign body intrusion check implement described in the utility model comprises two monitoring means 1,2 that are provided with at interval; Described each monitoring means 1,2 constitutes by modulation circuit 3, demodulator circuit 4, obliquity sensor circuit 5 and cpu chip; Modulation circuit 3 mouths in two monitoring means 1,2 are electrically connected with demodulator circuit 4 input ends in another monitoring means by covered wire 6,7 respectively, thoroughly do away with edge lead 6,7 with described two and be woven into net structure to constitute monitoring net, the area of net is changeable according to actual needs; The obliquity sensor circuit 5 in each monitoring means 1,2 and the mouth of demodulator circuit 4 are electrically connected with cpu chip input interface in this unit respectively; Cpu chip mouth in two monitoring means 1,2 realizes that by communication bus and upper early warning main frame communication is connected.
