The leveling period ambient temperature may be an average ambient temperature of the leveling period.
The leveling period start date may be the same as the heating season start date. The leveling period ambient temperature can be predicted from historical temperature data prior to the heating season. When the environment temperature and the heating temperature in the leveling period are greater than preset values, the frequency of the leveling period acquisition period can be increased, and when the environment temperature and the heating temperature in the leveling period are less than the preset values, the frequency of the leveling period acquisition period can be reduced.

Specifically, the balance period information includes a balance period start/end date and a balance period ambient temperature, the balance period start date is the same as the balance period end date, and the balance period end date is the same as the heating season end date. The equilibrium period ambient temperature may be the average ambient temperature of the equilibrium period.

The index variation corresponding to the balance index in the current year can be predicted according to the historical balance index variation, and the balance period acquisition period of the heat metering system in the current year is determined according to the predicted index variation corresponding to the balance index in the current year. The larger the predicted index variation corresponding to the balance index in the current year is, the shorter the interval time of the acquisition period is set, namely, the data acquisition frequency is improved; conversely, the longer the interval time of the acquisition period is set, i.e., the data acquisition frequency is decreased.
Optionally, the heat metering system further includes a cloud server, the cloud server is in signal connection with the intelligent valve, and after the steps of sending a data acquisition instruction to the serial device and controlling the power supply to power off the serial device after receiving the response data of the serial device, the response data can be stored according to a preset format to obtain data to be reported; when a reporting period begins, reporting data to be reported to a cloud server; and when all the data to be reported are reported, controlling the intelligent valve to enter a dormant period.
In the embodiment of the present invention, the reporting period may be a period of time after one data acquisition is completed, or may also be a period of time after n data acquisitions are completed, where n is an integer greater than 1.
And after the intelligent valve receives response data returned by the serial port equipment, storing the response data according to a preset format. The preset format can be in time sequence or serial port equipment number sequence.

Further, as shown in fig. 3, fig. 3 is a flow chart of data acquisition provided in the embodiment of the present invention, in fig. 3, the NB-IoT valve is in a sleep state for most of the time, and is automatically woken up to start a data acquisition task when a next acquisition cycle arrives, first, it is determined whether a serial device is accessed to a power supply port, if the serial device is accessed, a power supply output is turned on to supply power to an external serial device (such as a pressure sensor and other devices that need to supply power), then, the RS485 master station is turned on, a data acquisition instruction is sent, after a serial device responds to data, the RS485 master station is turned off and power supply output is stopped, the data is stored according to a specific format, and is reported to a cloud when a next reporting cycle arrives, and the device enters a sleep period again.
Further, as shown in fig. 4, fig. 4 is a schematic diagram for determining an acquisition period according to an embodiment of the present invention, in fig. 4, the period may be divided into a heating season and a non-heating season every year, wherein the heating season is divided into a leveling period and a balancing period, and in the first few days of heating every year, the valve opening is required to be adjusted according to the pipe pressure and the return water temperature to achieve thermodynamic and hydraulic balance. At the moment, the requirement on the data acquisition period is short, and a short acquisition period can be set remotely. And after leveling is finished, the leveling period is started, the return water temperature and the pipeline pressure change are small, the valve opening adjustment almost tends to be stable, the requirement on the data acquisition period is not large, and a long acquisition period can be set remotely. And the heating system stops running at the moment when the heating season is finished and enters a non-heating season, and the equipment does not need to acquire data any more and can remotely stop the data acquisition function. Through the steps and the strategy, the service life of the valve battery can be prolonged as much as possible.
Furthermore, a data acquisition period can be set in a remote mode, the acquisition period is dynamically adjusted according to different requirements on the updating frequency of data in project requirements and heating seasons and non-heating seasons, and the service life of the battery is prolonged.
Furthermore, the collected heat of the heat meter, the return water temperature and the pressure data of the pressure sensor can be used for linkage control with the opening of the valve, for example, the valve is closed when the heat reaches a specified value, the opening of the valve is adjusted to enable the return water temperature to be close to the set temperature, and the like.
