Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] Referring to Figures 1 to 22, a back-end machine control system of a general monitoring system, the front-end machine is the core part of the entire monitoring center. The front-end computer receives the operating parameters of the back-end computer, and then sends the corresponding parameters to each collection terminal. On the other hand, the front-end computer also monitors the running status of the acquisition terminal, and uploads the status parameters to the back-end computer.

[0034] Define the digital switch: the switch state of the acquisition terminal (such as the voltage alarm of the device), including the input digital switch and the output digital switch. The alarm of the digital switch value is judged by the acquisition end and sent by the front-end computer. Analog quantity: The acquisition terminal collects and converts some analog quantities ...

Abstract

A front end machine control system of a general supervisory control system is disclosed. The front end machine is an embedded microprocessor for polling scanning acquisition end and memorizing scanned data in the front end machine, and the rear end machine communicates with the front end machine to fetch or set data of the acquisition end under the front end machine, comprising defining digital switch quantity, communication is initialed by the front end machine, the slave machine responses by using one-ask-one-answer modus, the data frame format comprises: a starting sign, a frame head, content, a check code, and an ending sign; performing normal data query, setting acquisition end output digit on-off value, setting acquisition end alarm parameter fluctuating value, front end machine setting acquisition end input on-off status quantity and setting acquisition end all parameters collocation. The front end machine control system of a general supervisory control system is provided with good expansibility, lowered cost, and waste is avoided when production scale is increased.

Description

technical field [0001] The invention relates to monitoring software of a monitoring system, in particular to a control system of a front-end machine. Background technique [0002] With the continuous development of the information society, monitoring systems are becoming more and more popular among manufacturers. In the existing monitoring system technology, the scalability of the back-end machine, the front-end machine and the collection end is poor. The front-end machine equipment and the back-end machine equipment are both implemented by hardware equipment, which is costly. When the production scale of the hard PLC expands, the hard PLC control system with a larger capacity can only be used, so that the original hard PLC will be scrapped accordingly, which is bound to cause a lot of waste. Contents of the invention [0003] In order to overcome the disadvantages of poor scalability and high cost of the front-end software of the existing monitoring system, the present ...
