Double-radio-frequency multi-frequency-point wireless system

Abstract

The invention discloses a double-radio-frequency multi-frequency-point wireless system which comprises a main control MCU, a module MCU, radio frequency 1, radio frequency 2 as well as three working frequency points, that is, a receiving frequency point 1, a receiving frequency point 2 and a transmitting frequency point, wherein three parameters of the defaulted receiving frequency point 1, the receiving frequency point 2 and the transmitting frequency point are stored in the main control MCU when the double-radio-frequency multi-frequency-point wireless system is delivered; when the double-radio-frequency multi-frequency-point wireless system is electrified, the main control MCU automatically transmits two receiving frequency points and one transmitting frequency point used at present to the module MCU, so that the module MCU can configure the two radio frequencies according to the received parameters; when the double-radio-frequency multi-frequency-point wireless system works, the module MCU can automatically change the radio frequency working frequency points according to received instructions so as to avoid external interference. Therefore, the technical effects that the system throughput rate is increased, the system response time is shortened, the same frequency interference is avoided, and the frequency points can be automatically changed to avoid the interference when being interfered are achieved.

Description

technical field [0001] The invention relates to the field of wireless signal transmission, in particular to a dual-radio multi-frequency point wireless system. Background technique [0002] With the improvement of living standards and the strengthening of environmental protection awareness, people's daily cooking fuels have changed from conventional energy such as firewood and coal, which are seriously wasted and polluting, to clean energy such as natural gas, coal gas, and even electricity. The gas meter will play its role here. With its automatic accumulation function, those who use natural gas or piped gas can easily know how much gas they have used, so that they can pay according to the cubic meters of gas consumed every month. . [0003] Nowadays, the information transmission of gas meters has changed from IC card as a carrier to wireless information transmission. When transmitting information wirelessly, how to allocate and use frequency channels is a key issue. In ad...
