Embodiment Construction

[0039] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0040] figure 1 A schematic diagram of the communication system provided by the present invention. The communication system includes a communication subject A (the first communication subject) and a communication subject B (the second communication subject). The communication subjects A and B perform data interaction, and both have the function of receiving and transmitting. For data interaction in applications, strict requirements are placed on power consumption, and battery life has become a very important indicator in practical applications.

[0041] The second communication subject is used to generate RSSI determination information according to the data sent by the first communication subject, and the first com...

Abstract

In current applications, when a short distance wireless transceiver chip transmits and receives data, transmitting power and receiving power are fixed, usually in order to achieve the purpose of signal communication, the data are transmitted and received by utilization of maximum power/maximum gain, in actual applications, under most conditions, the data are not needed to be transmitted and received by utilization of the maximum power/maximum gain, and extremely large waste of power consumption is caused. The invention provides a method dynamically controlling the transmitting power and the receiving power of the transceiver chip, communication equipment and a communication system based on an RSSI, the transmitting power and the receiving power are further lowered according to the actual applications, the power consumption is reduced, and the service life of a battery is prolonged.

Description

technical field [0001] The invention relates to a method for reducing transmitting and receiving power through RSSI value in wireless communication, especially in short-distance wireless communication, so as to save power consumption. Background technique [0002] In short-distance wireless communication, power consumption has always been a difficult problem restricting its application. Manufacturers always try their best to reduce power consumption, improve product competitiveness and meet the power consumption requirements of products entering the market. [0003] In the current short-distance wireless communication, among the main bodies of the communication parties, each main body is mainly composed of a wireless transceiver chip, a main control chip and some peripheral devices. Reducing power consumption is mainly to use low-power devices, such as low-power wireless transceiver chips, low-power main control chips, etc. At the same time, based on the control of the main ...
