Problems solved by technology

[0003] Because the needs of underground voice communication are quite different from those of voice communication systems in densely populated areas such as cities, the existing relatively complete wireless voice communication systems, such as PHS, GSM, CDMA, etc., have high costs and low utilization rates. It cannot be widely used in coal mines due to reasons such as lack of dispatching functions, and the complete copying of existing civilian mobile communication systems cannot fully utilize the advantages of PHS, wasting a lot of system resources

Embodiment Construction

[0054] The method of underground voice access and seamless switching in coal mines is shown in Figure 1. The scheme of this method consists of three parts: dispatching center 2; wireless base station 1; underground wireless paging equipment 3. in:

[0055] 1. Wireless base station 1

[0056] For the wireless base station, after the message receiving module 1.1 receives the message, it sends the message to the judging module 1.2, and the judging module 1.2 is responsible for checking the correctness of the received message, and forwards the message that can be received to the logic module 1.3, and the logic module 1.3 Output the message to be sent to the message sending module 1.4 according to the received message, and update the message that the judgment module 1.2 can receive next time. After the message sending module 1.4 sends the message, turn on the timeout module 1.5. Timeout timing function, the timing is the next The time that message expects to arrive, if receive cor...

Abstract

A switching device of mobile voice communication in the underground coal mine and a switch-in process relate to realize the voice switch-in in the underground coal mine, to finish the transfer calling to any underground voice paging device by an in-ground control center through a wireless base station, and simultaneously to finish the transfer calling to the in-ground control center by the underground voice paging device through the wireless base station. The switch-in process adopts a TCP / IP (transport control protocol / internet protocol) on the communication between the in-ground control center and the wireless base station, and adopts the wireless mobile communication based on the modulation of FSK on the communication between the wireless base station and the underground voice paging device. The device mainly comprises three parts, namely that an in-ground control center (2), a wireless base station (1) and an underground wireless paging device (3). The switch-in process comprises the contents of the three parts, namely a voice switch-in process of an in-ground control center, a voice switch-in process is that the paging device calls the in-ground control center and a pager voice communication non seam switching process.

Description

technical field [0001] The invention relates to the ability to realize underground voice access in coal mines, complete the relay call of any underground voice paging equipment by the above-ground dispatching center through a wireless base station, and simultaneously complete the transfer of underground voice paging equipment to call the above-ground dispatching center through the wireless base station. In this access method, TCP / IP (Transmission Control Protocol / Internet Protocol) network communication protocol is used for communication between the dispatching center on the well and the wireless base station, and wireless mobile communication based on FSK modulation is used for communication between the wireless base station and underground voice paging equipment. Background technique [0002] In recent years, the rapid development of the national economy has sharply increased the huge demand for energy such as coal and electricity. With the increase in the number of coal mi...
