Universal remote terminal of MQTT server

Abstract

The invention provides a universal remote terminal of an MQTT server. The universal remote terminal comprises an external input switching value, an external input analog quantity, an external output switching value, an MQTT server remote terminal and the MQTT server. The MQTT server remote terminal comprises a power supply circuit, a communication module, a main control unit, a switching value input unit, a switching value output unit, an analog-digital interface unit, a display screen unit, a user communication unit and a storage unit. A wireless network of an existing communication operatorcan be used, data transmission is carried out based on an MQTT protocol, the MQTT client ID is unique, a user is supported to configure an IP address, a port number, a user name and a password, a userdata transmission protocol is fixed, and the universal remote terminal has the advantages of high security, high reliability, expandability, easy operation and the like, can meet the product performance requirements in the field of Internet of Things, greatly shortens the development time and reduces the development cost as a key component of system integration, and can bring more economic benefits.

Description

technical field [0001] The invention relates to the technical field of electric control, in particular to a terminal that users can perform remote output control through a wireless network of a communication operator. [0002] The invention relates to the technical field of data acquisition, in particular to a terminal which has the function of collecting analog signal and switching signal at a remote site and uploads the data to a cloud server. [0003] The invention relates to the technical field of the Internet of Things, in particular to a terminal for data transmission through the MQTT protocol. Background technique [0004] In today's society, due to the expansion of the Internet of Things technology and the scope of human activities, higher requirements are put forward for remote detection and control. It is required not only to realize convenient remote control operations, but also to improve the reliability of data transmission and ensure the security of user data. ...

AI Technical Summary

Problems solved by technology

[0013] Therefore, the existing remote terminals have insufficient understanding of the core needs of customers and products, cannot achieve modularization and generalization, and remain at the stage of "supporting customer customization". Fixed port number, fixed user name and password, manual configuration of client ID, poor data security, poor scalability, etc., and the data security and reliability are not enough, which wastes designers' time and complicated operation, which greatly increases The cost and complexity of the system have disadvantages such as unclear function division and long development cycle

, not only wasting the precious time of designers, but also constantly changing the design scheme due to different application scenarios, often because of incomprehension of new application scenarios, paying a lot of tuition in vain, wasting time, funds and manpower , resulting in poor user experience and limiting the development of the industry
