Transmitter control method and control device thereof

Abstract

A method for controlling a transmitter, comprising: awaking and initiating the transmitter by a trigger signal generated by a timer; detecting whether the transmitter receives an input control parameter from outside of the transmitter, and if yes, updating an input control parameter stored in the transmitter by using the received input control parameter; reading the input control parameter currently stored in the transmitter; performing operations based on the read input control parameter so as to control the transmitter to select one sensor signal from a plurality of sensor signals, amplify the selected sensor signal with a gain within a first gain range, and output the amplified sensor signal; and after determining that the transmitter has accomplished a task specified by the read input control parameter, resetting the timer, and entering into a sleeping state until the timer generates the trigger signal.

Description

technical field [0001] The present application relates to a transmitter control method and a corresponding transmitter control device. Background technique [0002] With the popularization and industrialization of IoT technology, the usage of sensors has increased tremendously. Usually, the analog signal of the sensor needs to be sent through the transmitter for further processing. Therefore, the demand and functional requirements for the transmitter are increasing. [0003] figure 1 It is a schematic diagram schematically illustrating a typical topology of sensors and transmitters in the prior art, and the connection relationship of each component contained therein is as follows figure 1 shown in . Such as figure 1 As shown in , the transmitters T1, T2, ... Tn in the prior art represented by the dotted line box need to provide corresponding different and uncommon amplifiers A1, A2, ... An according to different types of sensors S1, S2, ... Sn respectively Amplify the s...

AI Technical Summary

Problems solved by technology

This cost grows exponentially as the number of sensors increases

[0006] 2. The production cost of the transmitter is high

In this way, in order to share the cost, it is difficult to reduce the selling price of a single transmitter, and it is difficult to carry out mass production

[0007] 3. Waste of power and short system life

The transmitter has a low number of processing channels and cannot be reused. Moreover, each transmitter must be in a working state even when no data is needed, which not only wastes power, but also shortens the life of the system.

Usually a monitoring system is equipped with many kinds of sensors. Under the condition of slow data collection, for example, in the normal system with a collection interval of more than ten minutes, or even one or two hours or one day, this waste of power and short system life The phenomenon is particularly serious
