Sensor system and method based on multi-sensor, multi-transmission and multi-power supply mode

Abstract

The invention discloses a sensor system and a method based on multi-sensor, multi-transmission and multi-power supply, which includes the steps that: S1: a sensor module and a communication module connected to the system are detected; S2: the sensor module data at preset frequency is read and transmitted to a processor module. S3: whether the sensor data triggers a linkage control is determined according to the preset policy; if so, the output port of the system is entered into step S4 after connected to other device; on the contrary, step S4 is entered directly; S4: whether there is a communication module is determined, whether the communication module data is successfully transmitted is determined; if there is no communication module, other linkage control action is carried out. The method has the advantages that the data of each sensor can be collected to a single-chip microcomputer, after the encryption and decryption processing, then can be sent out through a wire or wireless dataframe; when the local area network signal fails to be transmitted, the wide area network signal can be automatically switched for retry and the reliability of the signal transmission is achieved.

Description

technical field [0001] The invention relates to the technical field of sensors and communication, in particular to a sensor system and method based on multi-sensor, multi-transmission and multi-power supply modes. Background technique [0002] A digital sensor refers to a sensor that adds or modifies an A / D conversion module to a traditional analog sensor so that the output signal is a digital quantity (or digital code), mainly including: amplifier, A / D converter, microprocessor (CPU), memory, communication interface, temperature test circuit, etc., as microprocessors and sensors become cheaper and cheaper today, fully automatic or semi-automatic (high-level operations through manual instructions, automatic processing of low-level operations) systems can Contains more intelligent functions and can obtain and process more and different parameters from its environment. [0003] At present, digital sensors generally use wired communication and external power supply, which have...

AI Technical Summary

Problems solved by technology

[0003] At present, digital sensors generally use wired communication and external power supply, which have disadvantages such as single design, difficult wiring, and troublesome maintenance.

And this kind of sensor also has data security problems caused by transparent transmission, because the technical reliability and cost are not well controlled

Moreover, the current penetration rate of multi-functional sensors is still relatively low.
