Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] Such as figure 1 As shown, the present invention provides an environmental monitoring control system, including a data acquisition device, an acquisition controller PLC and a cloud control system. Among them, PLC only has input, output and communication functions. PLC transmits data to the cloud control system through the EPON passive optical communication network with optical fiber as the medium. After the cloud control system completes data processing and analysis, it passes through the passive optical communication network. Send the output instruction to PLC to complete the control requirements. The da...

Abstract

The invention provides an environment monitoring and controlling system comprising a data acquisition device, an acquisition controller PLC, and a cloud control system. The PLC only has input, output and communication functions. The PLC transfers data to the cloud control system through an EPON passive optical communication network with an optical fiber as the medium, and an output command is transferred to the PLC through the EPON passive optical communication network after the cloud control system completes data processing and analysis, thus completing the control requirements. The cloud control system performs integrated operation on data transferred from other areas or systems, makes simulation analysis to obtain an optimal control scheme, and sends the optimal control scheme down to the PLC for control, thus realizing soft linkage between different areas or different systems. Meanwhile, by weakening the operation function of the PLC, the manufacture cost is decreased, the size is reduced, and PLC implementation, deployment and installation are facilitated. The system can also monitor the running status of equipment and control the running status of equipment and the environment status in real time.

Description

technical field [0001] The invention belongs to the field of environment monitoring and control, and relates to an environment monitoring and control system. Background technique [0002] In traditional environmental monitoring systems, PLC is usually used for data acquisition and control. The front-end sensors transmit the collected data and action signals to the PLC, and program the PLC to drive the digital and analog output points to control the actions of the actuators. At present, this control method is widely used in intelligent building control systems. [0003] The characteristic of the tunnel environment monitoring system is that each monitoring area is far away and the location is scattered, so it is impossible to use one PLC to control all the equipment. Usually a small PLC is used to control a single area, and each area operates independently. Small PLCs have poor computing and communication capabilities, so it is difficult to perform complex and high-speed li...
