The utility model crag falling rocks warning system compared with prior art has following beneficial effect:
1, can monitor disaster automatically and take place, in time send warning: one of prior art is to monitor side slope when being subjected to displacement, notifying the keeper, taking corresponding measure by relevant department again; Shortcoming is that monitoring periods is long, and labour intensity is big, reports to the police to have hysteresis quality, and influenced by human factor; Just timely train dispatch radio communication panalarm by signal Processing and on-the-spot acousto-optic panalarm of charge book unit starting and detection trigger alarm unit takes place in the disaster that native system monitors automatically, the process of whole monitoring and warning is finished automatically by system, need not manual intervention, real-time is stronger.
2, type of alarm is more independent, more reliable: two " geologic hazard detection and warning systems " of prior art need be returned to indication server or keeper with field monitoring data or image by modes such as internet or notes when the monitoring disaster, therefore must use in the effective overlay area of other communication mobile network such as GSM or GPRS network, rely on the service that the third party provides, if just can't use in the mountain area that does not have signal to cover; And native system is directly to transfer the driving driver in the intercom field intensity coverage to report to the police to entering row by existing train dispatch radio communication device, does not rely on the service that the third party provides fully; Simultaneously, when finding to have the disaster that jeopardizes train operation, the field staff takes place, and system is not when automatically reporting to the police, and on-the-spot guard also can report to the police by manual control unit direct control equipment or stops to report to the police according to on-the-spot needs, has further increased its reliability.
3, has charge book function (being equivalent to black box function): record is carried out in all operations, can carry out query analysis by computer management system.
4, can make full use of existing apparatus and equipment (as train dispatch radio communication) transformations and use, cost is low, is easy to promote.
5, have good economical, societal benefits: because native system has above-mentioned advantage, therefore, it is along the line to be specially adapted to be installed in the railway that crag falling rocks, landslide or rubble flow may take place, and has very strong specific aim; Can effectively detect the disaster generation that this class of crag falling rocks, landslide or rubble flow jeopardizes traffic safety; Once just can reduce tens for railway, the economic loss of units up to a million; If passenger vehicle can be avoided the loss of people's lives and properties, meaning is more great.Therefore this system has a good application prospect and economical, societal benefits.
