Description

Technical Field

[0001] This invention relates to the field of heating balancing valve technology, and more specifically, to an intelligent balancing valve communication method and an intelligent balancing valve based on the Internet of Things. Background Technology

[0002] With the development of smart heating technology, intelligent balancing valves have been widely used in various heating units. These valves are primarily responsible for collecting and reporting data from the heating pipelines and receiving commands to adjust the valve opening. In the entire heating system, there are numerous and widely distributed intelligent balancing valves, resulting in a complex signal environment at their locations. Furthermore, due to limitations, many intelligent balancing valves cannot be powered by mains electricity and must be powered by batteries.

[0003] The power consumption of intelligent balancing valves is mainly for uploading data, receiving commands, and controlling the execution components to execute commands. Currently, such as Figure 1 As shown, intelligent balancing valves on the market operate as follows when data collection and uploading are required: After startup, the intelligent balancing valve automatically searches for nearby networks within a set time (e.g., 60 seconds). If a network connection is successful, data is uploaded. Simultaneously, it waits for control commands within the next set time (e.g., 10 seconds). If no control command is received within 10 seconds, the intelligent balancing valve shuts down and waits for the next startup. If a control command is received within 10 seconds, the command is responded to and executed, then the valve enters another 10-second wait. If a network connection is unsuccessful, the valve shuts down and waits for the next startup. While this communication method is simple, due to the complex signal environment where the intelligent balancing valve is located, and when the environmental signal is poor, the intelligent valve is often started and stopped multiple times to reduce data loss and improve the success rate of valve operation. Summary of the Invention

[0004] The purpose of this invention is to propose a smart balancing valve communication method and a smart balancing valve based on the Internet of Things, so as to overcome the shortcomings of the existing technology.

[0005] To achieve the above-mentioned technical objectives, the technical solution of the present invention is implemented as follows:

[0006] A communication method for an intelligent balancing valve based on the Internet of Things, the method comprising the following steps:

[0007] 1) After the intelligent balancing valve is started, it determines the current working mode. The working mode includes balancing mode and non-balancing mode. In balancing mode, the valve needs to be operated. In non-balancing mode, only data needs to be uploaded. If it is currently in balancing mode, then execute steps 2) to 3). If it is currently in non-balancing mode, then execute step 4).

[0008] 2) Increase the network injection time beyond the normally set network injection time. If the network injection is successful, proceed to step 3). If the network injection fails, perform one frequency clearing. If the frequency clearing is successful, repeat step 2). If the frequency clearing fails, the intelligent balance valve will shut down.

[0009] 3) Wait for a control command within the normally set time. If no control command is received, the intelligent balancing valve will shut down. If a control command is received, the valve will respond to the command and execute it, and then repeat step 3).

[0010] 4) Reduce the network registration time from the normally set time. If the network registration is successful, proceed to step 5). If the network registration fails, clear the frequency and shut down the device.

[0011] 5) Reduce the waiting time for control commands from the normally set time. If no control command is received, the intelligent balancing valve will shut down. If a control command is received, the command will be responded to and executed, and then step 5 will be repeated.

[0012] An intelligent balancing valve includes a data transmission control module, wherein the data transmission control module performs data communication using the communication method described above.

[0013] Furthermore, it also includes a working mode setting module, which sets the data acquisition and uploading cycle of the intelligent balancing valve and adjusts the valve opening based on the application scenario of the intelligent balancing valve and the weather conditions.

[0014] The beneficial effects of this invention are as follows: This invention changes the communication working mode after each wake-up of the intelligent balancing valve from a single working mode to two working modes. The two working modes are distinguished by whether the intelligent balancing valve needs to adjust the valve. The mode that needs to adjust the valve is set to balancing mode, and the mode that does not need to adjust the valve is set to non-balancing mode. By reducing the network injection and no-message waiting time in non-balancing mode and increasing the network injection time, frequency clearing times and no-message waiting time in balancing mode, the working efficiency of the balancing valve in balancing mode is not only higher when the intelligent balancing valve uploads the same amount of data, but also the effect of saving flow consumption is achieved.

In balancing mode, the valve needs to be operated. In non-balancing mode, only data needs to be uploaded. If it is currently in balancing mode, then execute steps 2) to 3). If it is currently in non-balancing mode, then execute step 4).

[0028] 2) Increase the network injection time beyond the normally set network injection time. If the network injection is successful, proceed to step 3). If the network injection fails, perform one frequency clearing. If the frequency clearing is successful, repeat step 2). If the frequency clearing fails, the intelligent balance valve will shut down.

[0029] 3) Wait for a control command within the normally set time. If no control command is received, the intelligent balancing valve will shut down. If a control command is received, the valve will respond to the command and execute it, and then repeat step 3).

[0030] 4) Reduce the network registration time from the normally set time. If the network registration is successful, proceed to step 5). If the network registration fails, clear the frequency and shut down the device.

[0031] 5) Reduce the waiting time for control commands from the normally set time. If no control command is received, the intelligent balancing valve will shut down. If a control command is received, the command will be responded to and executed, and then step 5 will be repeated.

[0058] The present invention also discloses an intelligent balancing valve, including a data transmission control module, wherein the data transmission control module performs data communication using the communication method described above.

[0059] Furthermore, it also includes a working mode setting module, which sets the data acquisition and uploading cycle of the intelligent balancing valve and adjusts the valve opening based on the application scenario of the intelligent balancing valve and the weather conditions.

[0060] Specifically, for office buildings or educational buildings, where personnel only use the equipment during working hours, such as 8:00 AM to 6:00 PM, and generally on weekends, a daily / weekly mode can be set. The actuator cycles in weeks, with a maximum of five daily modes (Schemes 1-5) per week. Monday through Sunday can each correspond to Schemes 1-5, and the motor opening automatically changes according to the parameters set on the platform. Example parameter settings are shown in the table below:

[0061]

[0062] For teaching buildings, students have winter and summer vacations, during which time the buildings are empty. In this case, the intelligent balancing valve can be set to vacation mode. When switching to this mode, if the current time is the start time, the valve opening changes to the initial opening; if the current time is not equal to the start time, the actuator opening remains unchanged. When the device enters vacation mode, the existing mode is paused until the end date, restoring the previous mode state and the opening before the start of vacation mode. Example settings are shown in the table below:

[0063]

[0064] For the entire year, heating is divided into heating season and non-heating season. When switching to this mode, the actuator opening remains unchanged. When the equipment reaches the start time of the non-heating season, the current mode is paused, the motor opening remains unchanged, and the data transmission interval becomes 72 hours. Until the end date, the motor opening does not change, and the previous mode is restored. An example of the setting parameters is shown below:

[0065]

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
