The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail, as shown in Figure 1, the present invention includes one group of controller that is connected on the CAN bus, be provided with single-chip data acquisition module and 485/CAN conversion communication module in each controller, and can detect and show one road dust signal, and can connect 2 road Infrared Detectors and 2 road water flow switch input signals, can control 2 way solenoid valves, and have RS232, RS485, CAN EBI, can realize data remote; Each controller is connected with dust sensor, phonetic alarm device and atomization mechanism, and dust sensor detects the dust concentration in the mine, and transfers data to controller.
Phonetic alarm device comprises voice case, phonetic synthesis module and voice signal transport module composition, it is that 16 ohm, power add the demonstration of red and green color original shape point matrix LED for the 5W loudspeaker that the voice case adopts impedance, adopt essential safety voltage 12V power supply, and added watchdog technique, in case locking system crashes, improved the stability of system, have the luminosity height, characteristics such as visual perspective is wide, and power consumption is little.The voice case is responsible for receiving the order that controller sends, and according to circumstances exports different voice suggestions; The voice signal transport module is connected with controller with the voice case, adopts RS485 to communicate by letter between this module and the controller, makes the distance of voice case and controller may extend to 1200 meters; The phonetic synthesis module adopts the technology of present state-of-the-art Text To Speech output, receive text to be synthesized by asynchronous serial port, can directly drive the voice case, also can outer order prop up triode driving voice case, can realize the conversion of text to sound by the PWM way of output.
Atomization mechanism comprises explosion-proof infrared sensor, anti-riot electromagnetic valve, water flow relay, shower nozzle and pipeline, explosion-proof solenoid valve is connected with explosion-proof infrared sensor with controller, and the control of controlled device and explosion-proof infrared sensor, water flow relay is provided with in the pipeline between explosion-proof solenoid valve and the shower nozzle, and is connected with controller.
Consider that the underground electric network voltage pulsation is bigger, therefore to be furnished with input range be AC85V～AC264V to controller, be output as the AC/DC transfer Switching Power Supply of the wide-voltage range of 12V, this Switching Power Supply comprises input rectification circuit, input rectification circuit is connected with converter, converter is connected with output rectification circuit again, as shown in Figure 4 and Figure 5, wherein input rectification circuit is eliminated from electrical network, startup as motor, the switch of electrical equipment, the interference that thunderbolt etc. produce, prevent that also the high-frequency noise that Switching Power Supply produces from spreading to electrical network, simultaneously the electrical network input voltage is carried out rectifying and wave-filtering, for converter provides DC voltage, converter is by inverter, control circuit and holding circuit are formed, inverter is the key component of Switching Power Supply, and it becomes high-frequency ac voltage to DC voltage change, and plays the effect that output and input electrical network are isolated; Control circuit detects output dc voltage, and itself and reference voltage are compared, amplify, and the pulse width of modulating oscillator, thus the control change device is to keep the stable of output voltage; Holding circuit quits work with protection load and power supply itself Switching Power Supply when Switching Power Supply generation overvoltage, overcurrent short circuit.The high-frequency ac voltage rectifying and wave-filtering that output rectification circuit is exported converter obtains the DC voltage of needs, also will prevent the interference of high-frequency noise to load simultaneously.
Operating principle of the present invention is: when dust sensor is sensed airborne dust concentration above certain numerical value, controller is just controlled explosion-proof solenoid valve and is opened and make shower nozzle spraying, automatic dustfall, phonetic alarm device also sends corresponding alarm sound simultaneously, sense shower nozzle people from below when explosion-proof infrared sensor and arranged through out-of-date, just close explosion-proof solenoid valve, spraying is temporarily stopped, treat that the people is through row spraying more later, water flow relay detects the flow of the water in the water pipe, when explosion-proof solenoid valve is opened, if do not have current through water pipe, water flow relay just transmits signals to controller, and controller is just controlled phonetic alarm device and for example sent sound such as " please open water flow switch ", has realized the automatic monitoring of online in real time of dust concentration and the function of automatic warning and depositing dust.
