Embodiment 1

[0023] Such as figure 1 The shown underground wireless DCS safety monitoring system includes a wireless network, which is set in the safety helmet of the underground staff for real-time collection of various environmental parameters for sensing and forming a sensing module 1 for environmental parameter signals; for receiving the environmental parameters The signal is processed and generates the A / D conversion module 2 of the transmission data; the data processed by the A / D conversion module 2 is transmitted by the digital-analog transmission module 3 in a relay multi-hop mode; the digital-analog transmission module 3 will The data is transmitted to the server 4 and then transmitted to the processor 6 located at the monitoring center through the signal transceiver module 5; , communicate with the processor 7 through the wireless network. It also includes a GPS positioning module 7, and the GPS positioning module 7 communicates with the server 4 through the wireless network. ...

Embodiment 2

[0027] Such as figure 2 The sensing module includes a microprocessor 8, a sensor 9 connected to the microprocessor 8, and an alarm; the alarm is a light source 10 and a buzzer 11; the microprocessor 8 is also connected to a power supply 12. The sensor 9 includes an image sensor 9-1, a temperature sensor 9-2, a humidity sensor 9-3, an atmospheric pressure sensor 9-4, a methane sensor 9-5, a hydrogen sulfide sensor 9-6, a carbon monoxide sensor 9-7 and an oxygen sensor 9-8.

[0028] In the present invention, various downhole environmental parameters such as image, temperature, humidity, atmospheric pressure, methane concentration, hydrogen sulfide concentration, carbon monoxide concentration and oxygen concentration are provided with one-to-one corresponding detection sensors, and the relevant environmental parameters collected are in the agreed frame format Through the signal transceiver module, all the information is collected on multiple digital-analog transmission modules;...

Abstract

The invention provides an underground wireless DCS (data communication system) safety monitoring system comprising a wireless network, a sensor module, an A/D (analog/digital) conversion module, a digital-analog transmission module, a server, a signal transceiver module and a processor. The sensor module, the A/D conversion module, the digital-analog transmission module, the server, the signal transceiver module and the processor are in communication by the wireless network. Environmental index parameters of different positions underground can be monitored by the system at any time and then sent to the processor of a monitoring center to be subjected to information analysis so as to realize early warning; further, accident locations of mines can be determined within a short time, emergency processing scheme making is facilitated, and safety of underground operators is guaranteed effectively.

Description

technical field [0001] The invention relates to an underground safety monitoring system of a coal mine, in particular to an underground wireless DCS safety monitoring system. Background technique [0002] Working underground in coal mines, due to the influence of geological conditions, environment and toxic and harmful gases, various mine accidents occur frequently, causing serious damage to life and property, so the safe operating environment in coal mines is our current and long-term work focus. Although some products and equipment developed for the field of underground safety monitoring in coal mines, especially alarm devices for dangerous gases, have been widely developed and applied. But basically they all use simple gas sensors to collect the concentration signal of dangerous gas, and start alarming when the concentration exceeds a certain standard. Moreover, various alarm devices are decentralized control systems, that is, all devices operate independently and are n...
