In order to make the objects, technical solutions and advantages of the present invention more apparent, the following description is made by way of specific embodiments with reference to the accompanying drawings.
Fig. 2 is a flowchart of an implementation of a method for heat station cycle pump control according to an embodiment of the present invention.
Step S201, acquiring real-time monitoring data of the primary network.
Step S202, acquiring historical monitoring data of the primary network, and determining the fault probability of the circulating pump according to the real-time monitoring data, the historical monitoring data and the fault judgment condition so as to control the running state of the circulating pump according to the fault probability.
Wherein, real-time monitoring data and historical monitoring data all include: the water supply temperature, the water return temperature and the opening degree of the electric regulating valve; the historical monitoring data comprises monitoring data in a plurality of historical periods adjacent to the real-time monitoring data.
In the embodiment of the method, the obtained opening degree of the electric regulating valve is the opening degree of the electric regulating valve between the water supply branch of the primary network and the heat exchanger.
In this embodiment, the real-time monitoring data and the historical monitoring data of the primary network are acquired, the fault probability of the circulating pump is determined according to the real-time monitoring data, the historical monitoring data and the fault judgment condition, and the operation state of the circulating pump is controlled according to the fault probability, that is, the operation state of the circulating pump is indirectly judged through the real-time monitoring data and the historical monitoring data of the primary network of the heating power station system under the condition that the operation frequency of the circulating pump cannot be acquired, so that the control measures are timely taken when the circulating pump of the heating power station is judged to be in fault.

The accuracy of judging the running state of the circulating pump is improved based on various parameters, the misjudgment rate of the running state of the circulating pump is reduced, and the misoperation of the circulating pump control is reduced.
In various embodiments, the operating state of the circulation pump is optionally controlled on the basis of the failure probability determined once or more.
In one possible implementation, after a single determination of the failure probability of the circulation pump according to the foregoing embodiment, the failure state of the circulation pump is determined according to the determined failure probability, and relevant control measures are taken. Specifically, when confirming that the fault probability is greater than the fault threshold value, confirm the circulating pump trouble promptly, in time control the circulating pump and shut down and generate early warning information, be convenient for relevant personnel to carry out the circulating pump and overhaul the operation, avoid heating untimely reduction user experience.

Optionally, the number of times of repeatedly determining the failure probability is 2 to 5 times. The repeated execution times are not suitable to be too many, and the operation of determining the fault probability for multiple times is avoided when the circulating pump breaks down, so that the running time of the circulating pump in the fault state is prolonged. In an embodiment of the present invention, the process of determining the probability of failure is repeatedly performed 3 times.
In one possible implementation, the method further includes: and when the fault probability determined for a plurality of times continuously does not meet the shutdown condition, increasing the running frequency of the circulating pump or maintaining the running state of the circulating pump.

And judging that the opening of the electric regulating valve of the primary network is within a normal fluctuation range based on the opening and the opening average value of the real-time electric regulating valve. When the circulating pump breaks down, because can not normal heat transfer, when the electricity governing valve of a net normally opened, a net return water temperature can rise, based on real-time return water temperature, return water average value as the judgement basis of return water temperature change. In addition, when the circulating pump breaks down, because can not normal heat transfer, the temperature difference can diminish gradually once, consequently, supply back the temperature difference and supply back the temperature difference average value as the judgement basis based on supplying in real time.
In one possible implementation, the fault determination condition includes: a first condition, a second condition, and a third condition;

I.e. when the temperature threshold is 2 deg.C, the first condition is t1-t1AVG>2 ℃, wherein t1 is the real-time backwater temperature, t1AVGThe average value of the backwater in a plurality of historical periods adjacent to the real-time monitoring data is obtained.
Optionally, under the second condition, the first ratio is 90% and the second ratio is 110%. I.e. the second condition is | V-VAVG|÷|VAVG|*100％<10%, wherein V is the opening of the real-time electric regulating valve, VAVGThe opening average value of the electric regulating valve in a plurality of historical periods adjacent to the real-time monitoring data is obtained.
Alternatively, in the third condition, the third ratio is 70% and the fourth ratio is 130%. That is, the third condition is | t2-t2AVG|÷|t2AVG|*100％>30%, wherein t2 is the real-time supply-return temperature difference, t2AVGThe average value of the supply and return temperature differences in a plurality of historical periods adjacent to the real-time monitoring data is obtained.
In one possible implementation, the method for determining the fault probability of the circulating pump according to the real-time return water temperature, the return water average value, the real-time electric regulating valve opening, the opening average value, the real-time supply and return temperature difference, the supply and return temperature difference average value and the fault judgment condition includes the following steps:
when any one of the first condition, the second condition and the third condition is met, determining the fault probability of the circulating pump as a first probability;
when the first condition and the second condition are met, or the first condition and the third condition are met, determining the fault probability of the circulating pump as a second probability;
when the second condition and the third condition are met, or the first condition, the second condition and the third condition are met, determining that the fault probability of the circulating pump is a third probability;
wherein the first probability is less than a probability threshold; the second probability is equal to the probability threshold; the third probability is greater than the probability threshold.
In a specific embodiment, the corresponding relationship of the failure probability of the corresponding circulation pump meeting different conditions is as follows:
| condition of satisfaction of the condition | Probability of failure |
| Satisfying only the first, second, or third conditions | 30％ |
| Satisfies a first condition and a second condition | 60％ |
| Satisfies the first and third conditions | 60％ |
| Satisfy the second and third conditions | 90％ |
| Satisfy the first condition, the second condition and the third condition at the same time | 90％ |
Wherein the probability threshold is 60%. In one embodiment, the fault state of the circulation pump is judged based on three consecutive fault probability calculation results, and each calculation result is more than 60%.
In a possible implementation manner, before obtaining the historical monitoring data of the primary network, the method further includes:
obtaining the standing opening degree of the electric regulating valve in a closed state;
executing the operation of acquiring the historical monitoring data of the primary network when the opening of the electric regulating valve in the real-time monitoring data is larger than the opening of the standing valve
