Fig. 1 is the communication structure schematic diagram of described coal mine safety monitoring system.
The specific embodiment
Below by the specific embodiment, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of coal mine safety monitoring system, it comprises ground central station main frame 1, ground central station main frame 2, communication mode converter and downhole monitoring substation.
Wherein, described communication mode converter comprises microcontroller circuit, data storage circuitry, photoelectric isolating circuit 1, photoelectric isolating circuit 2, bus communication module 1, bus communication module 2, RS232 communication module 1 and RS232 communication module 2, described microcontroller circuit connects respectively described photoelectric isolating circuit 1, described photoelectric isolating circuit 2, described RS232 communication module 1 and described RS232 communication module 2, described photoelectric isolating circuit 1 be connected photoelectric isolating circuit 2 and connect respectively described bus communication module 1 and described bus communication module 2, described microcontroller circuit connects described data storage circuitry so that described microcontroller circuit is condensed to resolution data with the packed data decompress(ion) that receives and is stored in the described data storage circuitry.
Described ground central station main frame 1 be connected ground central station main frame 2 by the RS232 communication mode respectively with the RS232 communication module 1 of described communication mode converter are connected with the RS232 communication module be connected so that described ground central station main frame 1 or/and described ground central station main frame 2 read the resolution data in the described data storage circuitry and send order to described communication mode converter.
