Referring to fig. 2, based on the above hardware architecture, the embodiment of the present application further discloses a heat supply metering method with a monitoring function, including steps S100 to S400:
step S100: and acquiring the indoor temperature and the target temperature, and outputting a room temperature adjusting instruction to the temperature control valve based on the difference value of the indoor temperature and the target temperature so as to control the opening and closing of the temperature control valve.
The room temperature remote control module forms room temperature difference information with the indoor temperature and the target temperature after acquiring the indoor temperature and the target temperature expected to be adjusted by a user, then sends the room temperature difference information to the room temperature on-off controller, the room temperature on-off controller sends a room temperature adjusting instruction to the temperature control valve, and when the temperature control valve is opened, circulating water circulates to adjust the indoor temperature.
Referring to fig. 2 and 3, step S200: and recording the working time of the temperature control valve based on a preset time period, obtaining the heat value of the user based on the working time of the temperature control valve and the preset indoor area of the user, and recording and outputting the heat value.
Because the currently common heat calculation method is an on-off time area method, which is related to the indoor area and the heat circulation time, the time for opening the temperature control valve and the indoor area of the user need to be acquired, then the heat value consumed by the user in the current time period is calculated according to the existing heat calculation formula, and then the heat value is sent to the heat collection box.
The step S200 includes steps S210 to S230:
step S210: and recording the working time of the temperature control valve based on a first preset time period, obtaining the heat consumed by the user based on the working time of the temperature control valve and the preset indoor area of the user, and recording and outputting the heat.
For example, the first preset time period is 1 hour interval, and the heat consumption per 1 hour is calculated according to the working time of the thermostatic valve and the indoor area of the user, and then recorded and outputted to the heat collecting box.
Step S220: and recording the working time of the temperature control valve based on a second preset time period, obtaining the heat consumed by the user based on the working time of the temperature control valve and the preset indoor area of the user, and recording and outputting the heat.
For example, the first preset time period is 1.2 hour intervals, and the heat consumption per 1.2 hours is calculated according to the working time of the thermostatic valve and the indoor area of the user, and then recorded and outputted to the heat collecting box.
Step S230: the second preset time period is greater than the first preset time period.
The second preset time period is larger than the first preset time period, the collected time periods can be distributed in a staggered mode, the heat consumption per hour is prevented from being regular, the heat consumption of the first preset time period is collected, the heat consumption of the second preset time period is also collected, and the accuracy of judging whether the heat consumption value exceeds a normal heat consumption interval or not at the back can be improved.
Referring to fig. 2 and 4, step S300: and obtaining the normal heat consumption interval of each user based on the historical data of the heat value of the user in the preset time period.
The step S300 includes steps S310 to S370:
step S310: and obtaining a first normal heat consumption interval of each user based on historical data of the heat value consumed by the user in a first preset time period.
Historical data according to past heat values show certain regularity, so that the normal water consumption of the user is in the water consumption law, for example, the past heat consumption value of the user every 1 hour is obtained, and a heat consumption range formed according to the historical data is used as a normal interval of the user.
Step S320: and obtaining a second normal heat consumption interval of each user based on the historical data of the heat value consumed by the user in a second preset time period.
Historical data according to past heat values show certain regularity, so that the normal water consumption of the user is in the water consumption law, for example, the past heat consumption value of the user every 1.2 hours is obtained, and a heat consumption range formed according to the historical data is used as a normal interval of the user.
Step S330: and judging whether the historical data of the heat value accords with normal distribution.
As for some random water use data, as long as the historical data are enough, whether the data meet the rule of normal distribution or not is judged, and if the data do meet the rule of normal distribution, the interval range with high probability formed by the historical data is used as the heat consumption interval of the user according to the rule of normal distribution.
Step S340: and if the historical data of the heat values are not in accordance with the normal distribution, ending the flow.
If the historical data does not meet the regularity of normal distribution, any historical data cannot be used as a reference standard, and a more accurate normal user heat consumption interval cannot be formed according to the historical data.
Step S350: and acquiring historical data of the heat values consumed by all other users in the preset time period, wherein the historical data is the same as the indoor area of the user.
Since a plurality of users exist in the same building, for other users in the same indoor area, the heat value depends on the working time of the temperature control valve, and all historical data can also meet the normal distribution rule.
Step S360: and calculating the probability that the heat value of all the users exceeds the respective normal heat consumption interval based on the historical data of the heat value.
And the probabilities of whether other users are in the corresponding normal heat consumption intervals are respectively calculated, so that the probability that the whole building exceeds the normal heat consumption intervals can be summarized, and unified management can be facilitated.
Step S370: and when the probability is higher than the probability threshold value, outputting a four-level alarm signal.
If the probability of the whole building exceeding the normal heat consumption interval is higher than the probability threshold value, the fact that the heat supply system of the whole building breaks down is indicated, a four-level alarm signal is output to inform relevant personnel, the four-level alarm signal can be in an audible and visual alarm mode, and when the four-level alarm signal appears, the fault needs to be eliminated in time.
Referring to fig. 2 and 5, step S400: and when the heat value of the user continuously exceeds the normal heat consumption interval for many times, outputting an alarm signal.
The step S400 includes steps S410 to S450:
step S410: and when the heat value of the user in the first preset time period exceeds the first normal heat consumption interval, judging whether the heat value of the user in the second preset time period exceeds the second normal heat consumption interval.
Step S420: and when the heat value of the user in the second preset time period exceeds the second normal heat consumption interval, adding 1 to the number of times of the excess value.
When a user acquires heat values of a plurality of continuous first preset time periods, the heat values of the plurality of continuous first preset time periods exceed a first normal heat consumption interval, if the heat values exceed the maximum value of the normal heat consumption interval, the problem of heat supply metering of the user is proved, if the heat values are lower than the minimum value of the first normal heat consumption interval, the problem that some special users (such as solitary old people and children) cannot conveniently and timely open a heat supply device to supply heat is proved, the old people and children may be frozen, whether the heat values exceed the first normal heat consumption interval or not needs to be judged, in order to improve the judgment accuracy, the heat values of a plurality of continuous second preset time periods need to be acquired, then whether the heat values of the plurality of continuous second preset time periods exceed the second normal heat consumption interval or not is judged, and if the heat values exceed the second normal heat consumption interval, the problem of heat supply metering of the user is proved to be really caused.
Step S430: and repeating the process, and outputting a three-level alarm signal when the number of times of the exceeding reaches the threshold value.
When a user obtains a heat value of a first preset time period, and the heat value of the first preset time period exceeds a first normal heat consumption interval, the problem of heat supply metering of the user is proved, in order to improve the accuracy of judgment, the heat value of a second preset time period needs to be obtained, then whether the heat value of the second preset time period exceeds a second normal heat consumption interval is judged, and if yes, the problem of heat supply metering of the user is proved.
Step S440: and when the heat value of the user in the first preset time period continuously exceeds a first normal heat consumption interval for multiple times, outputting a first-level alarm signal.
When the user obtains the heat values of a plurality of continuous first preset time periods, if the heat values of the plurality of continuous first preset time periods exceed the first normal heat consumption interval, the problem of heat supply metering of the user is further proved to be really caused.
