Universal sensor control equipment and system

Abstract

The invention provides universal sensor control equipment and system. A data bus interface is used for receiving a setting command from an MCU, and transmitting the setting command to a master controller; the master controller sets current states of a data acquisition interface and a data acquisition device according to the setting command; the set data acquisition interface receives data information transmitted by sensors, and transmits the data information to the data acquisition device; the set data acquisition device transmits the received data information to the data bus interface through the master controller, so that the data bus interface transmits the data information to the MCU. According to the equipment and the system, by the interconnection and intercommunication of the data acquisition device and each sensor, various personalized transmitters are unified, investment cost is reduced, and the operation is simple; a working mechanism like that of a programmable logic controller is realized, universality for sensors and transmitters, correctness and low cost are achieved, and the equipment and the system play an important role in the interconnection of things, rapid application and market promotion.

Description

Technical field [0001] The present invention relates to communications, electronics, data acquisition, sensor conditioning circuits, etc., in particular, to universal sensor control equipment and systems. Background technique [0002] With the rapid development of information technology, the Internet of Things has also been greatly popularized, and the Internet of Things platform based on the Internet of Things is also being used more and more. The core part of the Internet of Things platform is to collect data and information through sensors. , And transmit the data information to the database server, and then the controller terminal obtains the information from the database server, and performs subsequent control according to the information. [0003] However, in the above-mentioned IoT platform, data cannot be directly transmitted between the sensor and the database server. This requires a conversion device as an intermediate bridge to convert the type of transmitted data inform...

Problems solved by technology

[0004] The inventor found in the research that the software of the embedded information acquisition module in the prior art can only be connected to a single sensor after being solidified. If the user needs multiple sensors during use, multiple adapted embedded information modules are required. Acquisition module, which makes the input cost high, and the operation is cumbersome, and the versatility is poor
