Remote data terminal and system thereof, and remote data terminal operating method

Abstract

The invention relates to a remote data terminal, a remote data terminal system and a remote data terminal operating method. The remote data terminal comprises a data storage module, a cloud configuration acquisition instruction module and a communication module, wherein the cloud configuration acquisition instruction module is connected with serial port equipment, which is about to acquire data, of the remote data terminal, and is used for transmitting an acquisition instruction to the serial port equipment and receiving original data returned by the serial port equipment; the data storage module is directly connected with the cloud configuration acquisition instruction module, and is used for storing the original data returned by the serial port equipment and transmitting the stored original data to the communication module by means of the cloud configuration acquisition instruction module when the remote data terminal needs to be connected with a server; and the communication module is connected with the server, and is used for transmitting the original data to the server and transmitting a received configuration file issued by the server to the cloud configuration acquisition instruction module.

Description

technical field [0001] The invention relates to the field of remote terminal control, and specifically designs a remote data terminal and its system, as well as a working method of the remote data terminal. Background technique [0002] The remote data terminal is the core device that constitutes the comprehensive automation system of the enterprise. It is usually composed of signal input / output modules, microprocessors, wired / wireless communication equipment, power supplies, and housings. It is controlled by the microprocessor and supports the network system. Through its own software (or intelligent software) system, it can ideally realize the functions of remote measurement, remote control, remote signaling and remote adjustment of the primary instrument on the production site by the enterprise central monitoring and dispatching system. [0003] Existing remote data terminals such as figure 1 As shown, it includes a data storage module 61, a cloud configuration acquisitio...

Problems solved by technology

[0004] Therefore, because the existing remote data terminal puts the analysis of data in the remote data terminal on site, it needs to be connected and debugged during use, and the remote data terminal needs to be set with serial port or PC software; if it is a new device, for Example Identify field devices, send different data collection instructions for different devices through the serial port, and for the device data returned by the serial port, in order to develop different analysis programs for different devices, it is necessary to develop software for the remote terminal device and update the remote terminal device Firmware, increasing the types of supported instruments, this process requires the participation of software developers, writing data processing programs for specific instruments, the cost is high, and on-site installation also requires parameter adjustments, the work process is cumbersome, and it is not conducive to large-scale deployment
