Example one
As shown in fig. 2, which is a schematic flow chart of an implementation of the method for controlling a multi-functional heat supply valve according to an embodiment of the present invention, the method may include the following steps:
and S21, collecting heat data information of the heat meter, wherein the heat data information at least comprises instantaneous heat information.
During specific implementation, the multifunctional heat supply valve controller collects heat data information of the heat meter, wherein the heat data information of the heat meter comprises but is not limited to the following information: instantaneous heat information, accumulated flow information, instantaneous flow information, inlet water temperature information, return water temperature information and inlet and return water temperature difference information. After the heat data information of the heat meter is collected, the multifunctional heat supply valve controller can determine the heat use information in the current statistical time according to the accumulated heat information collected this time and the accumulated heat information collected last time, and then update the available heat information according to the heat use information. Specifically, the heat usage information in the current statistical time is equal to the difference between the accumulated heat information collected this time and the accumulated heat information collected last time, and the available heat information is updated by subtracting the difference from the available heat information obtained when the heat meter data was collected last time.
Preferably, the multifunctional heat supply valve controller may further receive prepaid charging information sent by the client through the acquisition calculator, determine corresponding information of the prepaid heat quantity according to the prepaid charging information, and update the available heat quantity information according to the information of the prepaid heat quantity, specifically, determine that the information of the available heat quantity recorded by the multifunctional heat supply valve controller is current available heat quantity information by using the information of the prepaid heat quantity and the available heat quantity information, for example, the corresponding prepaid heat quantity in the prepaid charging information sent by the client is 100kwh, and if the current available heat quantity is 50kwh, the current available heat quantity after update is: 100+ 50-150 kwh. Or the available heat information is updated according to the accumulated pre-purchased heat information and the accumulated heat information, specifically, the multifunctional heating valve controller may record the accumulated pre-purchased heat information of the user, and a difference obtained by subtracting the accumulated heat information from the accumulated pre-purchased heat information is the available heat information, for example, the user charges three times in total, the accumulated pre-purchased heat of the first two times is 200kwh, the accumulated pre-purchased heat of the current time is 100kwh, after the current charging, the accumulated pre-purchased heat is updated to 200+100 ═ 300kwh, and if the accumulated heat information collected at a certain time is 180kwh, the available heat information is 300-. If the current available heat is judged to be larger than zero according to the available heat information, an opening instruction is sent to the electric valve to control the electric valve to be opened, and if the current available heat is judged to be smaller than or equal to zero according to the available heat information, a closing instruction is sent to the electric valve to control the electric valve to be closed.
In specific implementation, the multifunctional heat supply valve controller may further determine, according to the prepaid charging information, corresponding prepaid time information after receiving the prepaid charging information sent by the client through the acquisition calculator, and then update the available time information according to the prepaid charging information, specifically, determine, as the current available time information, the available time information recorded by the multifunctional heat supply valve controller and the prepaid time information, for example, if the corresponding prepaid time in the prepaid charging information sent by the client is 30 days, and the available time is 15 days, then the updated current available time is: 30+ 15-45 days.

If the current available time is judged to be larger than zero according to the available time information, sending an opening instruction to the electric valve to control the electric valve to be opened; and if the current available time is judged to be less than or equal to zero according to the available time information, sending a closing instruction to the electric valve to control the electric valve to be closed.
It should be noted that, after the electric valve is opened, the multifunctional heat supply valve controller can collect heat data information of the heat meter.
And S22, comparing the instantaneous flow information with a preset flow control threshold value to obtain a comparison result.
And S23, adjusting the electric valve according to the comparison result.
In specific implementation, if the instantaneous flow is determined to be smaller than the flow control threshold value according to the instantaneous flow information, the electric valve is adjusted to increase the flow, and if the instantaneous flow is determined to be larger than the flow control threshold value according to the instantaneous flow information, the electric valve is adjusted to decrease the flow. For example, the preset flow control threshold value of the power supply unit is 2.0, if the instantaneous flow of the heat meter collected by the multifunctional heat supply valve controller is 1.0, which is smaller than the flow control threshold value of 2.0, the electric valve can be adjusted to increase a certain opening degree to increase the flow, and if the instantaneous flow is 0.5, the electric valve can be adjusted to decrease the certain opening degree to decrease the flow.
It should be noted that, the step of updating the available heat information or the available time information by the multi-function heat supply valve controller may be before steps S22 and S23, or after steps S22 and S23, and the embodiment of the present invention is not limited.
In the method for controlling the multifunctional heat supply valve provided by the embodiment of the invention, the multifunctional heat supply valve controller acquires heat data information of a heat meter, the heat data information contains instantaneous flow information, the instantaneous flow information in the heat data information is compared with a preset flow control threshold value to obtain a comparison result, and the electric valve is adjusted according to the comparison result. The multifunctional heat supply valve controller receives the prepaid recharging information sent by the client, determines corresponding information of the prepaid heat quantity or the prepaid time according to the prepaid recharging information, and updates the available heat quantity information according to the information of the prepaid heat quantity or updates the available heat quantity information according to the accumulated information of the prepaid heat quantity and the accumulated heat quantity so as to achieve the purpose of prepaying the heat quantity; and updating the available time information according to the pre-purchase time information or updating the available time information according to the accumulated pre-purchase time information and the accumulated use time information so as to fulfill the aim of timing pre-payment, modify the residual amount information and finish remote recharging.
Example two
As shown in fig. 3, which is a schematic flow chart of an implementation of the method for controlling a multifunctional heat supply valve according to the second embodiment of the present invention, the method may include the following steps:
and S31, receiving the current room temperature information sent by the room temperature controller and the temperature information set by the user.
When the multifunctional heating valve controller is specifically implemented, the multifunctional heating valve controller receives the current room temperature information sent by the room temperature controller and the temperature information set by a user, and the room temperature controller can also send average temperature information to the multifunctional heating valve controller.
And S32, adjusting the electric valve according to the difference value between the current room temperature information and the temperature information set by the user.
When the multifunctional heat supply valve controller is specifically implemented, the electric valve is adjusted according to the difference value between the current room temperature information and the temperature information set by a user. Specifically, if the absolute value of the difference between the current room temperature information and the temperature information set by the user is within a preset range, the electric valve is kept unchanged; if the absolute value of the difference is not in the preset range and the difference is a negative value, adjusting the electric valve to increase the flow; if the absolute value of the difference is not in the preset range and the difference is a positive value, adjusting the electric valve to reduce the flow; and if the difference value is a positive value and is greater than a preset threshold value, closing the electric valve. For example, if the current room temperature information is 20 ℃, if the temperature information set by the user is 21 ℃, the preset range is (-1.5, 1.5), and the preset threshold is 6, the absolute value of the difference between the current room temperature information and the temperature information set by the user is 1, and the electric valve is kept unchanged within the preset range (-1.5, 1.5). If the temperature information set by the user is 25 deg.c, the difference between the current room temperature information and the temperature information set by the user is-5 deg.c, and the absolute value of the difference, 5, is not within the preset range (-1.5, 1.5), the electrically operated valve is adjusted to increase the flow rate, thereby increasing the room temperature. If the temperature information set by the user is 18 ℃, the difference between the current room temperature information and the temperature information set by the user is 2 ℃, and the absolute value 2 of the difference is not within the preset range (-1.5, 1.5), the electrically operated valve is adjusted to reduce the flow rate, so that the room temperature is lowered. And if the temperature information set by the user is 10 ℃, the difference value between the current room temperature information and the temperature information set by the user is 10 ℃, and the difference value is greater than a preset threshold value 6, and then the electric valve is closed. The preset range and the preset threshold value can be set by a user according to actual needs, and the embodiment of the invention is not limited.
In the specific implementation, if the valve is adjusted to change the temperature, and the instantaneous flow rate information corresponding to the temperature set by the user exceeds the flow rate control threshold preset by the power supply unit, the adjustment is not performed. For example, if the user sets a room temperature of 24 ℃ which requires an instantaneous flow rate of 1.0, but the heating unit sets a flow rate control threshold of 0.5, the valve controller will close the electrically operated valve when the instantaneous flow rate of 0.5 is reached, and no adjustment is made to the room temperature of 24 ℃.
In the method for controlling the multifunctional heating valve provided by the second embodiment of the invention, the multifunctional heating valve controller receives the current room temperature information sent by the room temperature controller and the temperature information set by the user, and adjusts the electric valve to control the flow according to the difference value between the current room temperature information and the temperature information set by the user.
In addition, in the multi-functional valve control methods provided in the first and second embodiments of the present invention, when the multi-functional heat supply valve controller receives a meter reading instruction from the upper computer collection calculator, the heat data information collected from the heat meter and the room temperature information received from the room temperature controller can be directly sent to the upper computer collection calculator, the upper computer collection calculator can separately manage and control heat supply of each user, and when the collection calculator collects heat meter data of a certain user, heat meters of other users do not need to be started, thereby greatly reducing heat meter power consumption of other users in the remote transmission system.
