Wireless communication equipment frequency matching method, module and system

Abstract

The invention discloses a wireless communication equipment frequency matching method, a wireless communication equipment frequency matching module and a wireless communication equipment frequency matching system. The method comprises the following steps: determining a plurality of to-be-matched frequency points of two pieces of interactive equipment; controlling one piece of interactive equipment to transmit a request signal to the other piece of interactive equipment at each to-be-matched frequency point; if one piece of interactive equipment receives a response signal fed back by other piece of interactive equipment, recording a frequency point corresponding to the response signal; and determining the frequency for communication of the two pieces of interactive equipment according to the recorded frequency point. According to the invention, the frequency deviation of transmitting and receiving signals of the two pieces of communication interactive equipment can be reduced and the communication effect can be improved.

Description

technical field [0001] The invention relates to the technical field of frequency matching, in particular to a frequency matching method, module and system for wireless communication equipment. Background technique [0002] At present, most wireless communication products on the market can only be used if the frequency matches (the same nominal frequency). There are accuracy errors in itself, coupled with differences in production processes and use environments, resulting in differences in the frequency of wireless products of the same model and specification. Because it meets the error requirements, that is, wireless products whose error is within the allowable error range are qualified, therefore, in actual use, they are usually used according to the frequency of the device when it leaves the factory. For example, for two wireless communication devices with a nominal frequency of 433MHz, one of the actual frequencies is 433.01MHz and the other is 433.05MHz. The actual fre...

[0003] In the prior art, such two wireless communication devices will send and receive signals according to their respective frequencies in practical applications. Since there is an error between the actual frequency and the nominal frequency of the two devices, the actual communication effect of the two devices There will be an impact, and with the increase of use time, the aging of the internal electronic components of the product will further increase the error of its frequency. The greater the error, the worse the communication effect, and even lead to no communication, affecting the service life of the product
