Dual-backup self-switching intelligent power supply device of wireless ad hoc network

Abstract

The invention discloses a dual-backup self-switching intelligent power supply device of a wireless ad hoc network. The device comprises a wireless communication module, a power supply circuit module,an antenna self-switching module and a micro-control unit main chip. The first power supply circuit module supplies power to the first wireless communication module, the second power supply circuit module supplies power to the second wireless communication module, the micro-control unit main chip controls the wireless self-switching module to connect the antenna with the first wireless communication module or the second wireless communication module, and the micro-control unit main chip controls the power supply circuit module. The invention provides a wireless ad hoc network double-backup self-switching intelligent power supply device, which is provided with two groups of wireless communication modules, wherein one group of wireless communication modules are standby devices; two corresponding groups of power supply circuit modules supply power to the two groups of wireless communication modules respectively, and the other group of wireless communication modules is automatically switched when one group of wireless communication modules fails; and meanwhile, the two wireless communication modules share the antenna, so that the problem of signal interference between the two antennasis solved.

Description

technical field [0001] The invention relates to a double-backup self-switching intelligent power supply device of a wireless ad hoc network. Background technique [0002] In the field of wireless communication technology, the networking of industrial lights refers to the use of wireless communication networking technology to connect all lamps with communication functions in lighting places to form a network of industrial lights. The industrial lighting network performs switch, dimming, and positioning control on each set of intelligent lamps within the control range, and can monitor the operating status of each set of lamps. The intelligent lighting terminal of the industrial lighting networking system is composed of intelligent power supply and lamps. [0003] The power supply is a commonly used electrical control device, but the power supply in the prior art has the following defects. First, when there is only a single wireless communication module, when the wireless comm...

Problems solved by technology

[0003] The power supply is a commonly used electrical control device, but the power supply in the prior art has the following defects. First, when there is only a single wireless communication module, when the wireless communication module fails, the system server and the intelligent lighting terminal will not be able to communicate normally. , which seriously affects the normal operation process; secondly, when two sets of wireless communication modules are used, although the problem that the system cannot communicate normally when a single wireless communication module fails, the two sets of wireless communication modules and the antennas of the two sets of wireless communication modules There is a problem of mutual interference between signals, and the closer the distance, the more serious the interference
