Wireless ad hoc network-based wireless repeater

Abstract

The invention discloses a wireless ad hoc network-based wireless repeater, which comprises a processor, a signal receiving unit, a signal data replication unit, a signal screening unit, a signal adjustment unit, a signal transmitting unit, a lightning-proof surge unit, a voltage stabilizing unit and a constant temperature control unit, wherein each functional unit is connected with the processor respectively; and the signal adjustment unit comprises a filter circuit, a signal attenuation compensation circuit, a signal error correction circuit and a signal amplifying circuit. According to the wireless repeater, the lightning-proof surge unit, the voltage stabilizing unit and the constant temperature control unit are arranged in the wireless repeater, so that lightning strike can be effectively prevented, stable working voltage and working temperature can also be provided for an internal circuit of the repeater, a stable working environment is provided for each circuit element for constituting the control circuit, a better protection effect on the repeater is realized, the environmental adaption capacity of the repeater is improved, and the service life of the repeater is prolonged.

Description

technical field [0001] The invention relates to a wireless repeater based on a wireless ad hoc network. Background technique [0002] A repeater is a device that connects network lines and is often used for bidirectional forwarding of physical signals between two network nodes. The repeater mainly completes the function of the OSI physical layer, is responsible for transmitting information bit by bit on the physical layer of the two nodes, and completes the functions of copying, adjusting and amplifying the signal, so as to extend the transmission distance of the network. The existing wireless repeaters have the following problems: they do not have the lightning protection function, and in seasons when lightning strikes are more frequent, repeaters used outdoors are easily damaged by lightning strikes, and the stability and reliability of use are poor. It does not have a temperature control function, especially in hot summer, the repeater under direct sunlight is easy to bu...

Problems solved by technology

The existing wireless repeaters have the following problems: they do not have the lightning protection function, and in seasons when lightning strikes are more frequent, repeaters used outdoors are easily damaged by lightning strikes, and the stability and reliability of use are poor

Although this method uses a two-stage lightning protection circuit, due to the defect of large residual voltage in the varistor, its residual voltage will increase with the increase of lightning energy, which is easy to cause damage to the load, and the lightning protection performance is unreliable. , easy to damage the wireless repeater
