[0042] The valve monitor of the present embodiment utilizes a monitoring method that differs significantly from gyroscopes or magnetic sensors. The sensor module is designed using a master switch and a rocker arm. The master switch does not require power to activate its switching action. By cleverly integrating the shape of a manual valve and cooperating with the rocker arm, the master switch drives the rocker arm when the manual valve's handwheel is rotated. The master switch triggers the generation of a forward or reverse rotation signal, which in turn triggers the valve monitor to report changes in the manual valve's status, requiring minimal energy consumption. Furthermore, compared to gyroscopes or magnetic sensors, the sensor module employed in the present embodiment is less susceptible to environmental factors, such as temperature, humidity, and magnetic fields, and is only affected by the rotation of the manual valve. Furthermore, the valve monitor of the present embodiment is configured with a first mode and a second mode. In other words, when no external trigger is present, the valve monitor can operate in a low-power or sleep state, reducing energy consumption. This makes it particularly suitable for applications without power wiring. With the same battery capacity, it can last several times longer, significantly reducing the frequency of battery replacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The monitoring device of the embodiment of the present application can access the network through a wired or wireless method, or through a combination of partially wireless and partially wired methods. Figure 1 As shown, an embodiment of the present application provides a manual valve status monitoring system, which can be composed of a wired access solution and a wireless access solution. The valve monitor 6 can be connected to the network after being connected to the explosion-proof wiring main box 1 through wiring. In the case where wiring cannot be performed, the valve monitor 6 is connected to the network wirelessly. The system includes a server 2, a wireless access device 5 and several valve monitors 6. The valve monitor 6 is used to collect and report the rotation status information of the manual valve 7. The wireless access device 5 is used to receive and forward the data reported by the valve monitor 6. The embodiment of the present application also includes an industrial gateway device 3, a data exchange device 4 and a visual display device. Several monitoring devices are connected to the network through the wireless access device 5. The wireless access device 5 is connected to the data exchange device 4. The data exchange device 4 is responsible for high-speed data forwarding between devices in the network. The industrial gateway device 3 communicates with the data exchange device 4 to provide remote management and control, and finally uploads the reported data to the server 2. The server 2 is used to visualize and analyze and display the data reported by the valve monitor 6.

[0050] See also Figure 2 The present embodiment includes a method for monitoring the status of a manual valve 7, which is applied to a valve monitor 6. The valve monitor 6 is at least partially located in the rotation path of the manual valve 7. When the valve monitor 6 is driven by the manual valve 7 to rotate, it triggers the generation of a forward rotation signal or a reverse rotation signal. The method includes the following steps S100 to S400:

[0051] Step S100: When a forward rotation signal or a reverse rotation signal is received, the working state is switched to a first mode state, which is a business state.

[0052] It should be noted that, see Figure 3 The valve monitor 6 of the embodiment of the present application includes a box body 61 installed at the manual valve 7, a sensor module 62 arranged on the box body 61, and a data transmission module 65 for communicating with the wireless access device 5. It should be emphasized that the valve monitor 6 is installed on the manual valve 7 with a handwheel, and the handwheel has spokes. The valve monitor 6 is at least partially located on the rotation path of the manual valve 7, that is, the sensor module 62 is partially located on the rotation path of the manual valve 7. When the sensor module 62 is driven by the manual valve 7 to rotate, it triggers the generation of a forward rotation signal or a reverse rotation signal. Specifically, the sensor module 62 includes a main switch 63, and the main switch 63 includes a movable rocker arm 64. The rocker arm 64 is located on the rotation path of the handwheel, and the rocker arm 64 can rotate left and right to trigger the generation of a forward rotation signal or a reverse rotation signal.

[0053] The valve monitor 6 includes at least two modes. The first mode is the business mode. In this first mode, all modules in the valve monitor 6 operate normally, and the communication delay between modules is small. The second mode is the sleep mode. In this second mode, except for the data transmission module 65 that periodically opens to monitor air interface data, other modules such as the signal processing module in the valve monitor 6 are in a low power consumption state or a sleep state. Only when an external trigger condition is received will the working state be switched to the normal business state. Specifically, in the embodiment of the present application, when the manual valve 7 rotates to drive the rocker arm 64 to rotate forward or reverse, the main switch 63 generates a forward rotation signal or a reverse rotation signal to trigger and wake up the other modules of the valve monitor 6.

[0054] In step S200, the rotation information of the manual valve 7 is obtained according to the number of forward rotation signals and reverse rotation signals and the preset calculation rules. The rotation information of the manual valve 7 is used to represent the number of forward rotation circles or reverse rotation circles of the current manual valve 7. The preset calculation rules are related to the handwheel spokes of the current manual valve 7.

[0055] It should be noted that when the handwheel is rotated forward to open the manual valve 7, the spokes of the handwheel reach the position of the rocker arm 64, and the rocker arm 64 is driven forward. The master switch 63 counts forward by +1. The rocker arm 64 is driven forward N times, and the master switch 63 counts forward by +N. Similarly, when the handwheel is rotated backward to open the manual valve 7, the rocker arm 64 is driven backward, and the master switch 63 counts backward by -N. For example, if the handwheel rotates forward three times and reverses once, the manual valve 7 currently rotates forward twice. When the valve monitor 6 is installed on the manual valve 7, a preset calculation rule can be set based on the number of handwheel spokes of the manual valve 7. For example, if the number of handwheel spokes is 3, if the master switch 63 counts forward by 4 and reversely by 1, the manual valve 7 has rotated forward once to open.

[0056] Step S300 , reporting a status change message of the manual valve 7 , and after receiving a response confirmation message, marking the manual valve 7 rotation information reporting as successful; the manual valve 7 status change message includes the manual valve 7 rotation information.

[0057] Before the above-mentioned step S100, the valve monitor 6 of the embodiment of the present application has been connected to the network. The valve monitor 6 can first send a request message, and after receiving the response message, establish a communication channel, report the manual valve 7 state change message, and after receiving the response confirmation message, mark the manual valve 7 rotation information as successfully reported. The manual valve 7 state change message includes the manual valve 7 rotation information and may also include a unique identification code for the message. The unique identification code can be generated in combination with the device ID information and the current time to avoid repeated data transmission.

[0058] Step S400: Switch the working state to the second mode state, which is the sleep state.

[0059] Existing solutions monitor the status of manual valve 7 by adding a gyroscopic sensor or magnetic sensor to the manual valve 7. Due to the characteristics of these sensors, they require power to operate normally and detect angular velocity or rotation angle, resulting in high energy consumption. Therefore, they can only be used in scenarios where electrical wiring is available. However, if there are a large number of manual valves 7, this wiring installation is difficult. Furthermore, it is not suitable for all petrochemical oil pipelines, potentially causing safety issues. Conventional batteries may only provide power for a few days or even less, requiring frequent battery replacement and unsuitable for situations with a large number of manual valves 7. Compared to the existing technologies, the valve monitor 6 of the present embodiment adopts a completely different monitoring method. The sensor module 62 is designed using a master switch 63 and a rocker arm 64. The master switch 63 does not require power to activate the switch. By cleverly integrating the shape of the manual valve 7 and cooperating with the rocker arm 64, the master switch 63 drives the rocker arm 64 to rotate when the manual valve handwheel rotates. The master switch 63 triggers the generation of a forward or reverse rotation signal, and the valve monitor 6 reports the status change of the manual valve 7, requiring minimal energy consumption. Furthermore, compared to gyroscopes or magnetic sensors, the present sensor module 62 is less susceptible to environmental influences, such as temperature, humidity, and magnetic fields, and is only affected by the rotation of the manual valve 7. Furthermore, the valve monitor 6 of the present embodiment is configured in a first mode and a second mode. In other words, in the absence of external triggers, the valve monitor 6 can be in a low-power or sleep state, reducing energy consumption. This makes it particularly suitable for applications without power wiring. With the same battery capacity, it can last several times longer, significantly reducing the frequency of battery replacement.

[0060] In the embodiment of the present application, before steps S100 to S400, a number of valve monitors 6 may experience access conflicts when first accessing the network, resulting in access failure. The longer the number of valve monitors 6 access time, the greater the energy consumption. Therefore, the embodiment of the present application optimizes the wireless access process to shorten the access time of the valve monitors 6. The specific method steps include the following:

[0061] Step A100: receiving a network access message broadcasted by the wireless access device 5 , the network access message including a time frame allocation quantity value; the time frame allocation quantity value is calculated based on the number of valve monitors to be accessed by the wireless access device 5 .

[0062] Before connecting to the network, valve monitor 6 can remain in the first mode and then switch to the second mode after connecting to the network, reducing power consumption. Valve monitor 6 may receive network access messages broadcast by multiple network devices (i.e., wireless access device 5) in the same time period. Based on the signal strength indicator (RSSI) and the allocated time frame value, valve monitor 6 can select the network device with the strongest signal strength and the largest allocated time frame value for network access. The allocated time frame value included in the network access message can be calculated based on the number of valve monitors in the sub-area. For example, if the number of valve monitors is estimated to be 200, the allocated time frame value can be 400.

[0063] Step A200: Generate a random variable value according to the time frame allocation quantity value and the device ID information, and send a response access request to the wireless access device 5 within the time frame segment corresponding to the current random variable value.

[0064] The minimum value of the random variable is 1, and the maximum value is the time frame allocation quantity (such as 400). By combining the unique identifier such as the device ID information to generate the random variable value, the random variable generated by the valve monitor 6 in the area can be dynamically changed, ensuring that the monitoring equipment has minimal conflict within a time period, allowing several valve monitors 6 to access the network within a time period, and speeding up the process of the valve monitor 6 accessing the network.

[0065] Network devices (such as industrial gateway devices 3 or wireless access devices 5) can infer signal conflicts based on the erroneous data received by the current wireless access device 5. If it is detected that there are a high number of conflicts in the access request of the current wireless access device 5, it is inferred that the monitoring devices in this area or this batch cannot currently access the network effectively, and it is necessary to expand the time frame allocation quantity value and then rebroadcast a new network access message. The new network access message includes a new time frame allocation quantity value, and the new time frame allocation quantity value is greater than the previous time frame allocation quantity value.

[0066] If a new network access message is received before the corresponding broadcast access completion message from the wireless access device 5 is received, a new random variable value needs to be generated again, and the above step A200 is repeated. In other words, the random variable value is generated based on the time frame allocation number value and the device ID information, and after sending a reply access request to the wireless access device 5 within the time frame segment corresponding to the current random variable value, the method includes:

[0067] A210: A new network access message broadcast by the wireless access device 5 is received within a preset time. The new network access message includes a new time frame allocation quantity value.

[0068] A220, if the new time frame allocation quantity value is inconsistent with the previous time frame allocation quantity value, a random variable value is generated again based on the time frame allocation quantity value and the device ID information, and a response access request is sent to the wireless access device 5 within the time frame segment corresponding to the current random variable value; until the access completion message broadcast by the wireless access device 5 is received.

[0069] In step A300, upon receiving the access completion message broadcast by the wireless access device 5, the current monitoring device is marked as connected to the wireless network; and a device status message is reported within the time frame corresponding to the random variable value. The device status message includes device ID information, battery power information, temperature information, manual valve 7 rotation information, and fault warning information.

[0070] It should be noted that the fault warning information is used to characterize the hardware fault condition of the current valve monitor 6, such as 001 characterizing the failure of the sensor module 62, 002 characterizing the power supply failure, etc. The message message of the embodiment of the present application can be defined based on the MQTT protocol.

[0071] Step A400: switch the working state to the second mode state.

[0072] After the valve monitor 6 is connected to the network, it can regularly report device status messages, and the server 2 can visualize this data to facilitate remote management and monitoring. The reporting time interval can be determined according to the system and energy consumption requirements. Specifically, the method also includes:

[0073] B100, regularly reports device status information; device status information includes device ID information, battery power information, temperature information, manual valve 7 rotation information and fault warning information; fault warning information is used to indicate the fault code of the abnormal status of the current monitoring device;

[0074] B200, after reporting the device status message, switches the working state to the second mode state.

[0075] It should be noted that before regularly reporting the device status message, the valve monitor 6 may be in the second mode, that is, in a dormant state or a low-power state. The timer can be configured to trigger an interrupt and start switching the working state of the valve monitor 6 to the first mode. After the business is processed, the working state can be switched to the second mode to achieve overall low power consumption and low energy consumption.

[0076] To achieve the above functions, the valve monitor 6 usually requires precise timing to ensure the reliability of data transmission. In the embodiment of the present application, the local clock source can be periodically corrected by receiving an external GPS clock signal. The method includes:

[0077] C100 periodically receives an external clock reference signal and determines a preset sampling range and an expected sampling value according to the type of the external clock reference signal.

[0078] It should be noted that the valve monitor 6 in this embodiment of the present application can include a built-in GPS receiver module to receive GPS clock signals. If the GPS clock signal is unavailable, it can also receive a broadcast clock synchronization signal to correct the local clock. The interval for regular reception can be determined based on system and energy requirements. If the signal type is GPS clock, the oscillator of the local clock source is searched and controlled to output a frequency related to the GPS clock signal, and the sampling range and expected sampling value are configured accordingly.

[0079] C200 counts the local clock signal output by the local clock source within the sampling range to obtain a sampled value. Specifically, the high-precision counter of the local clock source counts the clock signal output by the oscillator at this time. When the sampling range window is closed, the counting stops and the sampled value is obtained.

[0080] C300 compares the expected sampling value with the sampling value to obtain the difference result.

[0081] C400 adjusts the output clock frequency of the local clock source according to the difference result to correct the local clock source.

[0082] In step C400, the embodiment of the present application can adjust the output clock frequency in two steps. The first step controls the output clock frequency to be near the target frequency. The second step repeats the first step to correct the influence of various factors on the frequency, so that the clock signal frequency reaches the target frequency and the output clock frequency remains unchanged. Specifically, the method is as follows:

[0083] C410: When the difference result exceeds a first preset threshold, adjust a first clock frequency output by the local clock source.

[0084] C420, counting within a sampling range based on the local clock signal corresponding to the first clock frequency to obtain a new sampling value;

[0085] C430, compares the expected sampling value with the new sampling value to obtain a new difference result;

[0086] According to the difference result obtained in step C300, when it exceeds the first preset threshold, the frequency of the oscillator can be fine-tuned by adjusting the frequency control value of the local clock source, and the difference result can be re-counted and calculated to meet the first preset threshold so that the output clock frequency is near the target frequency, such as near the target frequency of 700MHz.

[0087] C440 , when the new difference result does not exceed the second preset threshold, adjust the second clock frequency output by the local clock source, and use the second clock frequency as the final corrected clock frequency.

[0088] That is, the output clock frequency needs to first meet the first preset threshold and then meet the second preset threshold at the target frequency, so that the clock signal frequency reaches the target frequency.

[0089] C450, after correcting the local clock source, switches the working state to the second mode.

[0090] The embodiment of the present application uses a phase-locked loop (PLL) to implement clock correction. Through the above steps C100 to C400, after two stages of frequency adjustment, a more stable clock frequency can be output to correct the local clock source.

[0091] In the second mode, most functions of the valve monitor 6 are turned off, with only a few modules such as the clock source maintaining low power consumption. The data transmission module 65 is periodically turned on to receive air interface data. Therefore, when the network device issues a service, the valve monitor device needs to be awakened. The method includes:

[0092] D100 , receiving the device wake-up message continuously broadcast by the wireless access device 5 within a preset air interface signal detection period; it should be noted that the air interface signal detection period can be preset according to the system and energy consumption.

[0093] D200, performs correlation sequence analysis on the received device wake-up message and the local wake-up reference sequence to obtain the peak result; at this time, the signal processing module is turned on to perform row demodulation and calculation processing on the data, and the data transmission module 65 is turned off. All peak results do not exceed the preset correlation threshold, and the data transmission module 65 continues to remain in sleep mode and wait for the next air interface signal detection cycle.

[0094] D300: If the peak value exceeds the preset threshold, the operating state is switched to the first mode. If at least one of the peak values exceeds the preset threshold, the air interface data is valid, and the functional modules of the valve monitor 6 are awakened, such as the data transmission module 65.

[0095] D400 receives service data sent by the network device in the first mode.

[0096] In the embodiment of the present application, before determining that the air interface data is valid, the data transmission module 65 and other modules can continue to remain in the second mode state to save energy consumption. After determining that the service needs to be received, it is adjusted to the first mode state, and in the first mode state, the service data sent by the network device is received and the service data is processed.
