Problems solved by technology

But on the one hand, the current heat exchange stations are all controlled separately, and multiple heat exchange stations in one area cannot be centrally monitored and resource shared, resulting in low production efficiency and inability to uniformly allocate resources. The thermal controller uses a simple PID control method to control temperature, flow, pressure and other control variables, result

Embodiment 1

[0033] Such as figure 1 As shown, an online monitoring system for a heat exchange station provided by an embodiment of the present invention includes: a cloud 1, a network 2, a control center 3 and a plurality of heat exchange stations 5; wherein:

[0034] Cloud 1 includes cloud resources, which are used to realize big data processing, and use cloud computing methods to realize the control of heat exchange stations. Cloud 1 can use cloud 1 provided by a public cloud service provider.

[0035] The control center 3 and the cloud 1 communicate through the network 2 , that is, the function of the network 2 is to provide communication between the control center 3 and the cloud 1 . The control center 3 is used to input user instructions, so as to set corresponding parameters according to the input user instructions, perform corresponding operations, and establish an index of cloud resources and other functions. The user instruction may include setting collection time and the like....

Embodiment 2

[0049] A control method for a heat exchange station provided in an embodiment of the present invention is implemented by using the online monitoring system for a heat exchange station as described in any of the above-mentioned embodiments. The control method specifically includes the following steps:

[0050] S1. Combined with the outdoor temperature and the heat dissipation of the pipelines of the secondary network connected to each heat exchange station, set the supply and return water temperature of the secondary network through the control center, including the set value of the water supply temperature of the secondary network and the return water temperature of the secondary network set value;

[0051] S2. The heat supply controller collects the heat supply operation data of each heat exchange station and summarizes them to the control center; the control center invokes cloud resources in the cloud through the network; the cloud executes genetic methods, parallel calculati...

Abstract

The invention relates to an online monitoring system and a control method for a heat exchange station. The system comprises a cloud side, a network, a control center and a plurality of heat exchange stations. The control method is realized by adopting the online monitoring system for the heat exchange station, and comprises the following steps of setting the water supply and return temperature of a secondary network through the control center in combination with outdoor temperature and the pipeline heat dissipating capacity of the secondary network; executing a genetic method, optimizing the PID control process of each heat supply controller, and adjusting the flow of a primary network by taking the error between an actual value and a set value of the water supply temperature of the secondary network as an adjusting parameter; executing the genetic method, optimizing the PID control process of each heat supply controller when the actual value of the water supply temperature of the secondary network reaches the set value of the water supply temperature of the secondary network; and adjusting the flow of the secondary network by taking the error between the actual value and the set value of the water return temperature of the secondary network as the adjusting parameter. According to the online monitoring system and the control method, centralized monitoring, data processing and resource sharing of a plurality of heat exchange stations at a district can be achieved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of industrial control, in particular to an online monitoring system for a heat exchange station and a control method for the heat exchange station. Background technique [0002] With the continuous progress of the national economy and the improvement of people's living standards, the society has higher and higher requirements for the environment. In recent years, cities and towns in northern my country have vigorously advocated central heating, changing the original heating of each unit and each area, reducing the pollution caused by the separate establishment of boiler rooms to the city, and one or more thermal power plants on the periphery of the city provide heat sources, and each district in the city A heat exchange station is established in the area to uniformly supply heat to heat users. In this way, the pollution of coal burning to the city is greatly reduced, and energy is also saved at the same time...
