Embodiment approach

[0043] The implementation scheme of the unattended thermal station control system is as follows:

[0044] The unattended system is divided into two parts: heat exchange station monitoring and dispatching monitoring center. The main function of the heat exchange station monitoring part is to realize manual / unattended operation. It is divided into remote / local control. Manual / automatic start-stop equipment operation. The thermal parameters and equipment status of the heat exchange station are uploaded to the thermal dispatching center, and the control command can be issued remotely from the dispatching center, and the video data of the equipment in the thermal station is uploaded to the video monitoring platform in real time. The equipment mainly includes programmable logic controller (PLC), frequency converter, heat meter, shut-off valve, temperature and pressure sensors, data communication equipment, etc., to realize thermal measurement, heat measurement, alarm shutdown, tempe...

Abstract

The invention discloses an unattended heating station control system and its working method, which belong to the technical field of heating pipe networks. The measurement module is used to collect real-time operating parameters of the thermal station, and the video monitoring module is used to collect real-time picture information of the thermal station. The measurement module and the video monitoring module are connected to the data processing module. The data processing module is connected to the data storage module and the lower computer module respectively. The machine module is connected with the communication module of the thermal station and all control points of the thermal station; the communication module of the thermal station is connected with the communication module of the dispatch monitoring center, and the communication module of the dispatch monitoring center is respectively connected with the upper computer module, the database module and the data analysis module, and the data analysis module Connect with the host computer module. The invention has a high degree of automation, improves the safety and stability of the thermal station operation, saves energy and protects the environment, and reduces labor costs.

Description

technical field [0001] The invention belongs to the technical field of heating pipe networks, and in particular relates to an unattended heating station control system and a working method thereof. Background technique [0002] In recent years, with the development of urban construction, the heating load has developed rapidly. At present, most heat exchange stations use manual monitoring, which wastes manpower on the one hand; on the other hand, it is difficult for operators to find hidden dangers of accidents, which may easily cause equipment accidents. At the same time, each heat exchange station operates independently, which makes it difficult to achieve the overall optimal state of the heating system, which may easily cause hydraulic imbalance, affect the heating effect and cause a great waste of energy. In addition, the heating dispatching department needs to know the basic heating operation parameters such as temperature and pressure of the heat exchange stations in e...
