Abstract
The invention provides a collapse prewarning system based on the WiFi technology. The system comprises an acquisition system, a wireless load transmitter, an installing support, an acquisition alarming control cabinet and a sound-light alarming device. A WiFi communication module and a Zigbee network data transmission module are arranged in the acquisition terminal, the wireless load transmitter is fixed to a tunnel through the installing support, the Zigbee network data transmission module is arranged in the wireless load transmitter, and the wireless load transmitter is connected with the acquisition terminal through the Zigbee network data transmission module. A WiFi communication module and a Zigbee network data transmission module are arranged in the acquisition alarming control cabinet, and the acquisition alarming control cabinet is connected with the wireless load transmitter and the acquisition terminal, the sound-light alarming device and a solar power supply device. The collapse prewarning system has the advantages that the WiFi bandwidth is high, speed is high, and safety is high; by means of the mode that a rechargeable lithium battery and solar charging are combined, power supply voltage is stable.
Description
Technical field
The present invention relates to early warning technology field, the early warning system more particularly, it relates to one kind is wirelessly caved in.
Background technology
In the tunnel building in or colliery, once there is cave-in accident, due to action of saving oneself can not be made in time, it will danger
And the life of many personnel on the scene.If cave-in accident can before caving in rather or send early warning, before being cave-in accident in several seconds
In hole, personnel win survival time, will save many life, reduce a large amount of loss.Existing early warning system is all as tunnel
Or the stretching into of coal mining, wired alarm device is gradually set in tunnel, because wired equipment needs in erection process
In be gradually increased the length of cable, increased equipment budget, and, in erection process, because plant equipment is more, also easily
Cable damage leads to the situation of signal interruption to occur, if now there is cave-in accident, consequence is hardly imaginable.
Current early warning system employs the mode of gprs or zigbee, based on the data transfer of gprs mode, needs to press
The moon pays data communication expense, is a no small expenditure for operation.Once data card occurs lose, being usurped by people, producing
The huge communication cost of life, causes larger loss.And the data being gathered by the method is first transmitted to public network, then by public network
Transmit to intra-field server, there is certain delay.
Content of the invention
Problem to be solved by this invention is to overcome the deficiencies in the prior art, the base that a kind of equipment is reliable, power supply is stable
Early warning system of caving in wifi technology.
The present invention solves its technical problem and takes technical scheme below to realize:
