And advanced at present mine fully mechanized mining supporter pressure gauge adopts wired or point-to-point communication to carry out data transmission.They are made up of pressure survey passage, pressure acquisition circuit, essential safe type circuit plate, wireless transport module, power circuit.Wherein the pressure acquisition circuit mainly is a resistance strain gage, and it is connected with essential safe type circuit plate, is used for the collection of pressure.Arrange signal processing circuit on the essential safe type circuit plate, signal processing circuit can be handled the signal that receives on request and transfer out through wired mode or point-to-point communication.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.And point-to-point wireless communication mode needs manual networking, and under the situation more in the monitoring point, that environment is abominable, networking mode is single, reliability is lower, safeguard relatively difficulty.
Summary of the invention
The purpose of the utility model is for overcoming the deficiency of mechanical type hydraulic measurement instrument and wire communication mode and point to point wireless communication mode, a kind of Internet of Things mode of wireless transmission fully mechanized mining supporter pressure gauge that can realize wireless transmission, automatic network-building being provided.
The structure that the utility model technical solution problem is adopted is: Internet of Things mode of wireless transmission fully mechanized mining supporter pressure gauge under a kind of coal mine comprises the pressure survey passage on housing, the housing, pressure acquisition circuit, power circuit and the essential safe type circuit plate in the housing; Wherein the pressure acquisition circuit is on the pressure survey passage, resistance strain gage to be set, and is connected with essential safe type circuit plate, is used for the collection of pressure; 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, and 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; It is characterized in that also be provided with wireless transport module on the essential safe type circuit plate, described wireless transport module is the module that can realize wireless transmission, automatic network-building, like the zigbee module.The signal transmission relation is:
The fully mechanized mining supporter pressure gauge is through the wireless transport module automatic network-building; Send the data of signal processing circuit recording processing in the network other sensors and special wireless routing node with the Internet of Things form; Wireless routing node sends subsequent processing device to, and subsequent processing device is monitored the fully mechanized mining supporter pressure under the coal mine more in real time.
Described pressure gauge has four pressure taps, can measure the pressure of four measuring points simultaneously.
Described pressure survey passage has one at least.
During use, this pressure gauge is fixed on the suitable location of fully mechanized mining supporter, the liquid of tested fully mechanized mining supporter pressure chamber draws through high-pressure oil pipe to be received on the manometric pressure tap.
The good effect of the utility model is: owing to adopt zigbee technology or other can realize that the technology of radio communication, automatic network-building carries out the transmission of the support works drag data of comprehensive mining hydraulic bracket; Need not connect up and can realize the automatic network-building of whole monitoring Internet of Things; Make that the pressure gauge configuration 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 pressure gauge has dissemination well.
