Problems solved by technology
Although most of the fixed and non-fixed gas monitoring devices used in coal mines in the past can send out an alarm sound when the gas concentration exceeds the standard, they cannot intelligently prompt the safe evacuation direction of the underground workers in the changing underground environment, which seriously affects the safety of underground workers. Safe and efficient evacuation of staff

specific Embodiment
[0031] like Figure 1~3 As shown, a new type of gas detection, early warning and emergency evacuation intelligent marking system based on LBS, including 220V power supply 1, electromagnetic relay 2, emergency low-voltage power supply (5V) 3, wireless remote control transmitter 4, buzzer 5, LED light-emitting diode 6. Tools such as gas sensor 7, single-way low-voltage receiving controller 8, sign 9 and wire 10.
[0032] The specific implementation steps are as follows:
[0033] like figure 1 and figure 2 As shown, the gas detection and early warning module is mainly composed of a gas sensor 7 and a buzzer 5. The gas sensor 7 uses the semiconductor gas sensor MQ-2 as the gas sensor. The sensor has fast response speed, good repeatability and selectivity, The performance of the components is stable, and it can detect combustible gas and smoke; the buzzer 5 is piezoelectric, driven by a crystal triode, and the vibration frequency of the low-voltage piezoelectric buzzer is 2300H...

The invention discloses a novel gas detection early warning and emergency evacuation intelligent marking system based on LBS. The novel gas detection early warning and emergency evacuation intelligentmarking system comprises a 220 V power supply, an electromagnetic relay, an emergency low-voltage power supply, a wireless remote control transmitter, buzzers, light emitting diodes (LEDs), gas sensors, single-circuit low-voltage receiving controllers, direction boards, wires and the like. The buzzers are connected with the single-circuit low-voltage receiving controllers and the gas sensors in series; the LEDs are connected with the single-circuit low-voltage receiving controllers; and after the gas concentration exceeds the standard, the 220 V power supply is disconnected, the electromagnetic relay is also disconnected, the emergency low-voltage power supply is connected, the emergency evacuation direction boards are maintained to be normally on during an accident, and the buzzers are connected to issue alarm signals. Signals of the single-circuit low-voltage receiving controllers are automatically broken, LED lamps of an indicating arrow on the side with gas are turned off, an arrow for indicating the safety direction on the other side is maintained to be normally on to guide personnel to be evacuated, early warning and escape indicating route providing can be accurately, practically and effectively conducted, and escaping and self-saving of miners under the sudden safety accident are guided.
Description
technical field [0001] The invention relates to a coal mine safety equipment technology, in particular to a novel gas detection, early warning and emergency evacuation intelligent marking system based on LBS. Background technique [0002] Since coal mine gas is one of the important factors affecting coal mine safety in the process of coal mining, the detection and alarm emergency technology of underground gas concentration is particularly important. In addition, in the process of emergency evacuation, the rapid and safe evacuation of the staff in the coal mine is also an essential means to achieve safe production in the coal mine. Although most of the fixed and non-fixed gas monitoring devices used in coal mines in the past can send out an alarm sound when the gas concentration exceeds the standard, they cannot intelligently prompt the safe evacuation direction of the underground workers in the changing underground environment, which seriously affects the safety of undergrou...
