Description

Technical Field

[0001] This invention relates to the field of manual valve structures, and in particular to a handle with manual valve status monitoring function and its control method. Background Technology

[0002] Currently, manual valves account for over 70% of water supply and drainage systems. Due to the large number and wide distribution of manual valves, coupled with a lack of monitoring devices, valve malfunctions frequently occur, causing not only adverse effects on users but also economic losses. This poses a significant challenge to system operation and management departments. With the advancement and development of smart water management, water supply and drainage system operation and management departments urgently need a device to monitor and manage manual valves remotely to track their operational status. Most existing manual valve handwheels lack operating handles; only a few have standard handles with only basic operating functions. These standard handles cannot monitor the valve's status. Summary of the Invention

[0003] The purpose of this invention is to overcome the defects of the prior art by providing a handle with manual valve status monitoring function and its control method.

[0004] The objective of this invention can be achieved through the following technical solutions: A handle with manual valve status monitoring function includes a hollow shaft, a bushing, a base, and a cover. The base is installed in the inner cavity of the hollow shaft and is equipped with a control terminal, a battery, and an antenna. The control terminal is connected to the battery and the antenna respectively for collecting, processing, and remotely transmitting valve status data. The bottom of the hollow shaft has a mounting hole for mounting on a valve handwheel. The bushing is fitted onto the outer side of the hollow shaft, and the cover is installed at the upper end of the hollow shaft, encapsulating the base inside the cavity of the hollow shaft.

[0005] Furthermore, the upper end of the inner cavity of the hollow shaft is provided with an internal thread, and the bottom of the cover is provided with an external thread. The cover is connected to the upper end of the hollow shaft by engaging with the internal thread of the hollow shaft through the external thread at the bottom.

[0006] Furthermore, the mounting hole is a screw hole, used to install the hollow shaft on the edge of the valve handwheel by bolts.

[0007] Furthermore, the control terminal includes a magnetometer, an accelerometer, a microprocessor, a BeiDou positioning module, and a communication module, all of which are connected to the microprocessor. The magnetometer is used to detect the rotation direction and rotation angle of the valve handwheel when the handwheel is in a horizontal position. The accelerometer is used to detect the rotation direction and rotation angle of the valve handwheel when it is in a vertical position. The Beidou positioning module is used to obtain the installation position of the valve handwheel; The microprocessor is used to accumulate the rotation angles of the corresponding sensors based on the rotation angle and corresponding rotation direction of the valve handwheel, and in combination with the installation position of the valve handwheel, to determine the real-time valve position value. It also uses the communication module to transmit data remotely via the built-in antenna, taking into account the installation position of the valve handwheel.

[0008] Furthermore, the top of the base is also equipped with an audible and visual alarm, which is connected to the control terminal, and the cover is provided with a cover window corresponding to the position of the audible and visual alarm; The audible and visual alarm is used to issue an audible and visual alarm when the control terminal does not receive a valve operation command or when the valve handwheel is mistakenly operated.

[0009] Furthermore, the control terminal and battery are both installed inside the base, and the antenna is installed on top of the base.

[0010] The present invention also provides another handle with manual valve status monitoring function, including a cover and a base. The cover has threaded holes at both ends, and the base has screw holes at both ends corresponding to the threaded holes. The cover is connected to the base by screws through the threaded holes and screw holes. A cavity is formed between the cover and the base, and a control terminal, a battery and a supercapacitor are installed in the cavity. The battery and the supercapacitor are installed in the base and connected in parallel to the control terminal. The control terminal is installed in the cover and has an antenna connected to the top for collecting, processing and remotely transmitting valve status data.

[0011] Furthermore, the control terminal includes a magnetometer, an accelerometer, a microprocessor, a BeiDou positioning module, and a communication module, all of which are connected to the microprocessor. The magnetometer is used to detect the rotation direction and rotation angle of the valve handwheel when the handwheel is in a horizontal position. The accelerometer is used to detect the rotation direction and rotation angle of the valve handwheel when it is in a vertical position. The Beidou positioning module is used to obtain the installation position of the valve handwheel; The microprocessor is used to accumulate the rotation angles of the corresponding sensors based on the rotation angle and corresponding rotation direction of the valve handwheel, and in combination with the installation position of the valve handwheel, to determine the real-time valve position value, and transmit the data remotely through the antenna via the communication module. The base is also equipped with an audible and visual alarm at the top, which is connected to the control terminal. The cover is provided with a cover window corresponding to the position of the audible and visual alarm. The audible and visual alarm is used to issue an audible and visual alarm when the control terminal does not receive a valve operation command or when the valve handwheel is mistakenly operated.

[0012] The present invention also provides a control method for a handle with manual valve status monitoring function as described above, comprising the following steps: The control terminal uses a magnetometer and accelerometer to collect the rotation angle and direction of the valve handwheel in real time when it is in the horizontal and vertical planes, respectively. If the valve handwheel rotates counterclockwise, the corresponding rotation angle is positive; if the valve handwheel rotates clockwise, the corresponding rotation angle is negative. The microprocessor accumulates the rotation angle values ​​of the valve handwheel and calculates the valve opening value, which corresponds to the real-time valve position value. The installation position of the valve handwheel is obtained in real time by the Beidou positioning module in the control terminal; The control terminal transmits the collected valve handwheel angle value, corresponding valve position value, and installation position to the monitoring and management platform via an antenna through the communication module. It also receives valve operation commands issued by the monitoring and management platform. If the valve handwheel is misoperated without receiving a valve operation command, an audible and visual alarm is triggered.

[0013] Furthermore, the method also includes: After installing the handle on the valve handwheel, the valve limit calibration is performed. The limit calibration process includes: rotating the valve to the fully closed position using the valve handwheel; the microprocessor records the rotation angle value of the valve handwheel at this time and calibrates the corresponding valve opening value as 0%; then rotating the valve to the fully open position using the valve handwheel, recording the rotation angle value of the valve handwheel at this time, the corresponding real-time valve position value, and calibrating the corresponding valve opening value as 100%, thus completing the valve limit calibration.

[0014] Compared with the prior art, the present invention has the following advantages: (1) This invention integrates the manual valve status monitoring function into the handle of the valve handwheel. A hollow shaft is installed on the valve handwheel, and a base is set inside the hollow shaft to install the control terminal, battery and antenna, etc., so as to have the function of collecting valve opening signals and uploading the collected valve opening value to the monitoring and management platform in a timely manner. A cover is installed on the top of the hollow shaft to encapsulate the base in the cavity of the hollow shaft and prevent the bushing from being moved out of the upper end of the hollow shaft. A bushing is fitted on the outside of the hollow shaft, and the valve handwheel can be rotated by holding the bushing to perform valve opening and closing operations. Using the handle of this invention to operate the valve during opening and closing is more convenient than using the handwheel directly. The structure is stable and reliable, and it enables monitoring of the valve status, facilitating digital management.

[0015] (2) It has the function of collecting valve installation location information: the present invention accurately obtains the valve installation location information and uploads it to the monitoring and management platform. The valve installation location information on the platform can be displayed in the form of a map.

[0016] (3) Valve identity information collection function: This invention provides a way to easily obtain valve identity information such as name, specifications, serial number, and installation time by setting a QR code.

[0017] (4) It has a valve operation alarm function: if the valve operated by the operator does not receive the operation instruction issued by the dispatch center, the control terminal will issue an audible and visual alarm signal. Attached Figure Description

[0025] Example 1 like Figure 1 and Figure 2As shown, this embodiment also provides a handle with manual valve status monitoring function, including a hollow shaft 6, a bushing 3, a base 5 and a cover 1. The base 5 is installed in the inner cavity of the hollow shaft 6. The base 5 is provided with a control terminal 4, a battery 7 and an antenna 2. The control terminal 4 is connected to the battery 7 and the antenna 2 respectively, and is used to collect, process and remotely transmit the status data of the valve 17. The bottom of the hollow shaft 6 is provided with a mounting hole for mounting on the valve handwheel 16. The bushing 3 is fitted on the outer side of the hollow shaft 6. The cover 1 is installed on the upper end of the hollow shaft 6 and encapsulates the base 5 in the cavity of the hollow shaft 6.

[0026] Optionally, the upper end of the inner cavity of the hollow shaft 6 is provided with an internal thread, and the bottom of the cover 1 is provided with an external thread. The cover 1 is connected to the upper end of the hollow shaft 6 by engaging with the internal thread of the hollow shaft 6 through the external thread at the bottom.

[0027] The upper threaded end of the hollow shaft 6 is fitted with a cover 1. The cover 1 encloses the base 5 inside the cavity of the hollow shaft 6 and restricts the bushing 3 from being moved out of the upper end of the hollow shaft 6. The bushing 3 can rotate around the hollow shaft 6.

[0028] Optionally, the mounting hole is a screw hole 8, used to mount the hollow shaft 6 to the edge of the valve handwheel 16 by bolts.

[0029] The hollow shaft 6 has a screw hole 8 at the bottom, through which the handle can be vertically installed on the edge of the valve handwheel 16 by bolts. By holding the shaft sleeve 3, the valve handwheel 16 of the valve 17 can be rotated to open and close the valve 17.

[0030] Preferably, the control terminal 4 includes a magnetometer 11, an accelerometer 12, a microprocessor 13, a Beidou positioning module 14, and a communication module 15, all of which are connected to the microprocessor 13. The magnetometer 11 is used to detect the rotation direction and rotation angle of the valve handwheel 16 when the valve handwheel 16 is in a horizontal position; The accelerometer 12 is used to detect the rotation direction and rotation angle of the valve handwheel 16 when the valve handwheel 16 is in the vertical position; The Beidou positioning module 14 is used to obtain the installation position of the valve handwheel 16; The microprocessor 13 is used to obtain the rotation angle value of the corresponding sensor based on the rotation angle and corresponding rotation direction of the valve handwheel 16 and the installation position of the valve handwheel 16, accumulate the rotation angle, calculate the real-time valve position value of the valve 17 through the formula, and transmit the data remotely through the antenna 2 via the communication module 15.

[0031] The microprocessor 13 also has the function of automatically identifying whether the valve handwheel 16 is in a horizontal or vertical position using a three-axis accelerometer. When the valve handwheel 16 is in a horizontal position, the acceleration on the Z-axis is 0; when the valve handwheel 16 is in a vertical position, the acceleration on the X-axis and Y-axis is 0.

[0032] Preferably, the top of the base 5 is also provided with an audible and visual alarm 10, which is connected to the control terminal 4, and the cover 1 is provided with a cover window 9 corresponding to the position of the audible and visual alarm 10. The audible and visual alarm 10 is used to issue an audible and visual alarm when the control terminal 4 does not receive an operation command for the valve 17 or when the valve handwheel 16 is misoperated.

[0033] The control terminal 4 and the battery 7 are both installed inside the base 5, and the antenna 2 is installed on the top of the base 5.

[0034] Specifically, in this embodiment, the handle with manual valve status monitoring function includes a hollow shaft 6, a bushing 3, a base 5, and a cover 1. The base 5 is equipped with a control terminal 4, a battery 7, an audible and visual alarm 10, and an antenna 2. The control terminal 4 integrates a magnetometer 11, an accelerometer 12, a microprocessor 13, a Beidou positioning module 14, and a communication module 15. The base 5 is installed in the inner cavity of the hollow shaft 6. The bottom of the hollow shaft 6 is provided with a fixing screw hole 8 for fixed connection with the valve handwheel 16. The upper end of the inner cavity of the hollow shaft 6 is also provided with threads. The bushing 3 is fitted on the outer surface of the hollow shaft 6 and can rotate around the hollow shaft 6. The cover 1 is fixed to the upper end of the hollow shaft 6 through the threads in the upper inner cavity of the hollow shaft 6, encapsulating the base 5 inside the cavity of the hollow shaft 6 and preventing the bushing 3 from being removed from the upper end of the hollow shaft 6. Holding the bushing 3 allows the valve handwheel 16 to be rotated to open and close the valve 17.

[0035] Example 2 like Figures 3-6 As shown, this embodiment provides a handle with manual valve status monitoring function, including a cover 1 and a base 5. The cover 1 has cover thread holes 19 at both ends, and the base 5 has screw holes 21 at both ends corresponding to the cover thread holes 19. The cover 1 is connected to the base 5 by screws 20 through the cover thread holes 19 and screw holes 21. A receiving cavity is formed between the cover 1 and the base 5. The receiving cavity contains a control terminal 4, a battery 7 and a supercapacitor 18. The battery 7 and the supercapacitor 18 are both installed in the base 5. The battery 7 and the supercapacitor 18 are connected in parallel to the control terminal 4. The control terminal 4 is installed in the cover 1 and has an antenna 2 connected to its top for collecting, processing and remotely transmitting the status data of the valve 17.

[0036] Battery 7 can provide a stable basic power supply; The supercapacitor 18 is connected in parallel with the battery 7 to provide power, which can prevent the battery voltage from dropping instantly due to the large current during data transmission, thereby affecting the stability of the microprocessor 13 and other electronic components.

[0037] Preferably, the control terminal 4 includes a magnetometer 11, an accelerometer 12, a microprocessor 13, a Beidou positioning module 14, and a communication module 15, all of which are connected to the microprocessor 13. The functions of each component in the control terminal 4 are the same as those described in Embodiment 1, and will not be repeated here.

[0038] The base 5 is also equipped with an audible and visual alarm 10, which is connected to the control terminal 4. The cover 1 is provided with a cover window 9 corresponding to the position of the audible and visual alarm 10, for viewing the audible and visual alarm signal.

[0039] The audible and visual alarm 10 is used to issue an audible and visual alarm when the control terminal 4 does not receive an operation command for the valve 17 or when the valve handwheel 16 is misoperated.

[0040] The handle provided in Embodiment 2 of the present invention is vertically mounted on the edge of the valve handwheel by screws. By holding the handle provided in Embodiment 2 of the present invention, the valve handwheel can be rotated to perform valve opening and closing operations.

[0041] Furthermore, Embodiment 2 of the present invention, like Embodiment 1, has multiple functions such as valve opening signal acquisition, valve installation position information acquisition, and valve operation alarm, and its performance and working principle are the same as those of Embodiment 1.

[0042] Example 3 This embodiment provides a control method for a handle with manual valve status monitoring function, as in Embodiment 1 or Embodiment 2, including the following steps: The magnetometer 11 and accelerometer 12 in the control terminal 4 collect the rotation angle and rotation direction of the valve handwheel 16 when it is in a horizontal position in real time. If the valve handwheel 16 rotates counterclockwise, the corresponding rotation angle is positive; if the valve handwheel 16 rotates clockwise, the corresponding rotation angle is negative. The rotation angles are accumulated, and the microprocessor 13 calculates the valve position value in real time based on the rotation angle value of the valve handwheel 16. The installation position of the valve handwheel 16 is obtained in real time by the Beidou positioning module 14 in the control terminal 4. The control terminal 4 transmits the collected rotation angle value of the valve handwheel 16, the corresponding valve position value, and the installation position to the monitoring and management platform via the antenna 2 through the communication module 15. It also receives valve operation instructions from the monitoring and management platform. If the valve handwheel 16 is operated by mistake without receiving the valve operation instructions, an audible and visual alarm will be triggered.

[0043] Specifically, in this embodiment, the magnetometer 11 and accelerometer 12 integrated on the control terminal 4 are used to detect the rotation angle and rotation direction of the valve handwheel 16 installed horizontally and vertically, respectively. The microprocessor 13 has the function of automatically identifying whether the valve 17 is installed horizontally or vertically through an algorithm, and uses the data collected by the corresponding sensors to calculate the valve position value.

[0044] Assuming the counterclockwise rotation angle of valve handwheel 16 is positive and the clockwise rotation angle is negative, when valve 17 is operated, microprocessor 13 accumulates the rotation angle values ​​of handwheel 16 during valve 17 opening and closing operations and stores the calculation results in the memory of microprocessor 13. The collected rotation angle values ​​of valve handwheel 16 are the same whether valve 17 is opened and closed via a handle or directly via valve handwheel 16.

[0045] Optionally, the method also includes: After installing the handle on the valve handwheel 16, the limit calibration of valve 17 is performed. The limit calibration process includes: rotating valve 17 to the fully closed position using valve handwheel 16, recording the valve position value determined by control terminal 4 at this time, and calibrating the opening value corresponding to valve 17 as 0%; then rotating valve 17 to the fully open position using valve handwheel 16, recording the valve position value determined by control terminal 4 at this time, and calibrating the opening value corresponding to valve 17 as 100%, thus completing the limit calibration of valve 17.

[0046] Specifically, in this embodiment, after the handle is installed, the limit of valve 17 needs to be calibrated upon first use. This involves performing a fully closed and fully open operation on valve 17. The system will automatically complete the limit calibration. First, when valve 17 is fully closed, a minimum angle value is generated. Microprocessor 13 records and saves this angle value and calibrates the opening value of valve 17 to 0%. Then, when valve 17 is fully open, a maximum angle value is generated. Microprocessor 13 records and saves this angle value and calibrates the opening value of valve 17 to 100%. This completes the limit calibration of valve 17.

[0047] Valve 17 opening value at any position = (current angle value - fully closed angle value) ÷ (fully open angle value - fully closed angle value) × 100% (round to the nearest integer) The control terminal 4 integrates a Beidou positioning module, which can accurately obtain the installation position of valve 17 and send the obtained installation position information of valve 17 to the monitoring and management platform.

[0048] The control terminal 4 integrates a communication module 15. The communication module 15 can not only transmit the data collected on site to the monitoring and management platform, but also receive instructions issued by the platform. In order to prevent the harm and adverse effects caused by the misoperation of valve 17, the operation of valve 17 is controlled by the dispatch center issuing operation instructions to the control terminal 4. If the control terminal 4 of the valve 17 being operated does not receive the operation instructions issued by the dispatch center, the audible and visual alarm 10 will issue an audible and visual alarm signal to warn of the operation error, and at the same time send the information to the equipment management personnel via SMS.

[0049] Optionally, a QR code can be set on valve 17. Scanning the QR code can obtain the valve 17's name, specifications, serial number, installation time, and other identification information, thus realizing the digital management of the manual valve 17.

[0050] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.

The installation position of the valve handwheel (16) is obtained in real time by the Beidou positioning module (14) in the control terminal (4); The control terminal (4) transmits the collected angle value of the valve handwheel (16), the corresponding valve position value, and the installation position to the monitoring and management platform via the antenna (2) through the communication module (15). It also receives the valve (17) operation instructions issued by the monitoring and management platform. If the valve handwheel (16) is misoperated when the valve (17) operation instructions are not received, an audible and visual alarm will be triggered.

10. The method according to claim 9, characterized in that, The method further includes: After the handle is installed on the valve handwheel (16), the limit calibration of the valve (17) is performed. The limit calibration process includes: rotating the valve (17) to the fully closed position through the valve handwheel (16), recording the valve position value determined by the control terminal (4) at this time, and calibrating the opening value corresponding to the valve (17) to 0%; then rotating the valve (17) to the fully open position through the valve handwheel (16), recording the valve position value determined by the control terminal (4) at this time, and calibrating the opening value corresponding to the valve (17) to 100%, thus completing the limit calibration of the valve (17).
