Embodiment Construction

[0021] The method of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] A method for saving electricity of a digital trunking channel machine, comprising the following steps:

[0023] 1) The digital trunking channel machine is powered on and initialized, and the transmitter of the digital trunking channel machine is turned on;

[0024] The channel machine is powered on and initialized, including the media access layer starting and entering the working state, and the physical layer starting and entering the working state.

[0025] 2) The media access layer of the digital trunking channel machine receives the data to be transmitted from the upper layer and buffers and assembles it. According to the channel type of the current time slot, it is judged whether the data of the current time slot needs to be sent to the air interface. If it needs to be sent, the The transmission permission flag of the current time s...

Abstract

The invention discloses a power-saving method of a digital cluster channel device, which belongs to the field of wireless communication, and especially relates to a digital cluster communication system device. The digital cluster channel device adopts the mode of time division multiplexing. The data block sent at each time slot goes with an emission allowing sign of the current time slot and an emission allowing sign of the next time slot. The switching-on / off status of a transmitter can be controlled through the combination of the two signs. The ineffective output power can be closed, and a real-time transmit power control mechanism based on time slot can be realized. The power efficiency and power-saving capability of the channel device can be improved.

Description

technical field [0001] The invention belongs to the field of wireless communication, in particular to digital trunking communication system equipment. Background technique [0002] The digital trunking channel machine system is a digital trunking wireless access system that complies with China's national standard for digital trunking. The system is suitable for industrial wireless private networks, including rail transit, electric power, ports, airports, government, military, etc. [0003] The digital trunking channel machine system realizes wireless access functions such as protocol stack physical layer, MAC layer, and radio frequency transceiver. It also provides local and remote management functions. The digital trunking channel machine adopts pure IP networking technology and redundancy technology to ensure system application flexibility and system reliability. Compared with the traditional channel machine, it has the advantages of high receiving sensitivity, strong a...
