The anchor stress meter that has automatic monitoring and data transmission at present adopts the wire communication mode to carry out data transmission.This anchor stress meter is made up of response body, stress measurement passage, stress Acquisition Circuit, essential safe type circuit plate, power circuit.Wherein response body is made up of inside and outside two open circles, and when roof or two walls were stressed, interior circle is stressed to move up and down, and produces dependent variable.Wherein the stress Acquisition Circuit is used for the collection of anchor stress, mainly is made up of resistance strain gage, and resistance strain gage is arranged on the stress measurement passage, and is connected with essential safe type circuit plate, converts dependent variable to electric signal and is sent on the essential safe type circuit plate; Be furnished with signal processing circuit and light-operated display on the essential safe type circuit plate; Wherein signal processing circuit is made up of filter amplification circuit, A/D change-over circuit and single chip circuit; Signal processing circuit is handled the signal that receives on request and is transferred out through wired mode; Light-operated display is connected with the signal processing circuit communication, through waking work up and show force value with mine lamp rayed display window.
Since the on-the-spot influence that receives the advance of the face of monitoring, frequent arrangement form and the installation site that needs to change sensor.Adopt wired communication mode, configuration is complicated, wiring, safeguards relatively difficulty, and down-hole working condition and circumstance complication are abominable, the disrumpent feelings fault of cable very easily occurs or poor contact phenomenon occurs, bring very big inconvenience to technical management.
Summary of the invention
The purpose of the utility model is for overcoming the deficiency of existing anchor stress meter, and a kind of not only wireless transmission but also anchor stress meter that can automatic network-building are provided.
The structure that the utility model technical solution problem is adopted is: Internet of Things mode of wireless transmission anchor stress meter under a kind of coal mine comprises response body, stress measurement passage, stress Acquisition Circuit, essential safe type circuit plate, power circuit; It is characterized in that, also be connected with wireless module on the essential safe type circuit plate, like the zigbee module with wireless transmission and automatic network-building function; Anchor stress meter housing is provided with antenna, and antenna is connected with wireless transport module through anti-water swivel, and wireless data is launched through antenna.The signal transmission relation is: the anchor stress meter is through the networking of the automatic constituent of wireless module, sends the data wireless of signal processing circuit recording processing in the network other sensors or special wireless routing node; Be transferred to subsequent processing device by other sensors or special wireless routing node then, subsequent processing device is monitored the fully mechanized mining supporter pressure under the coal mine more in real time.
During use, the anchor stress meter is fastened on coal mine roadway top board and two and helps anchor pole or the stressed monitoring point of anchor cable, and response body adopts the perforated fixed installation, puts into pallet earlier, and sensor is penetrated in the anchor pole, keeps sensor placed in the middle, the clamp nut of the anchor pole of screwing.
The good effect of the utility model is: can realize that the technology of wireless transmission, automatic network-building carries out the transmission of anchor stress Monitoring Data owing to adopt based on zigbee technology or other; Need not connect up and to realize the automatic network-building of whole monitoring Internet of Things; Make that the configuration of anchor stress meter is simple, easy to maintenance; Adapt to the complicated rugged surroundings in down-hole, be convenient to technical management.And can wake work up through mine lamp illumination, intuitive display, data processing function are strong etc.Therefore this anchor stress meter has dissemination well.
