Embedded data acquisition and equipment control system

Abstract

The invention discloses an embedded data acquisition and equipment control system. A software portion of the system consists of a data acquisition module, a data processing module, an equipment control module, a data storage module, a data transmission module, a data display module, a watchdog module and an embedded Web Server module. The software modules are developed by a Python language and run in a Python analyzer, development and maintenance difficulty of programs are low, modification is simple, and expandability is good. The embedded data acquisition and equipment control system can acquire various signals of digital quantity, analog quantity, an I2C (inter-integrated circuit), intelligent equipment and the like, and is capable of realizing control linkage for a relay and the intelligent equipment, configuration of the system is simple and flexible by the aid of the embedded Web Server module, remote upgrading of the system can be realized on the basis of the modules, and accordingly, the embedded data acquisition and equipment control system is applicable to places needing to acquire data and control equipment according to real-time data.

Description

technical field [0001] The invention relates to the fields of data acquisition and equipment control. Background technique [0002] Environmental monitoring, data acquisition and equipment control are required in various industries such as telecommunication equipment rooms and base stations, transportation, petroleum, chemical industry, and metallurgy. In different industries, or even in different environments of the same industry, the types of data that need to be collected are different, such as current, voltage, temperature, humidity, flow, pressure, etc.; the equipment that needs to be controlled is also different, such as alarm lights and speakers connected to relays, etc. There are also smart devices such as smart air conditioners and UPSs connected to serial ports. At present, it is difficult for a single embedded data acquisition and device control product to meet the increasingly complex application requirements, and repeated development will lead to problems such ...

AI Technical Summary

Problems solved by technology

[0004] 1. Programs based on μC / OS-II are developed using traditional C language, which makes program development and maintenance difficult and difficult to modify;

[0005] 2. If you want to increase the collection of switching values, or increase the control function of smart devices, you need to redesign the hardware and software, and the scalability is poor;

[0006] 3. Only A / D ports are used for data acquisition, and only analog signals can be collected;

[0007] 4. Only data acquisition function, no device control function;

[0008] 5. No server module, no remote upgrade function

Compilation in the development of embedded application software is very complicated. Different chip and hardware environments, different embedded operating systems, and different integrated development environments use different compilation tool chains, which requires secondary development technicians to understand The chip, hardware environment and operating system of the product must also learn the C / C++ language, and be able to use various compilation tool chains to compile the source code. If the integrated development environment is not free, it will cost a certain amount of money to purchase the integrated development environment

It can be seen that the traditional development method has high technical threshold, high development difficulty, and low technology reuse rate. Every secondary development may introduce new instability
