[0002] Usually before equipment maintenance, relevant operators will install several groups of grounding wires at specific electrical locations. The installation of the same group of A / B / C three-phase grounding wires is continuous and the time is relatively short, usually within a few minutes; during the equipment maintenance operation, except for the temporary removal of related equipment for some electrical tests and the loosening of grounding wires due to improper installation of grounding wires, the installation status of grounding wires usually does not change for a long time; when the maintenance task is completed and before the equipment resumes power supply, relevant operators need to remove the previously installed grounding wires, and the removal time of the same group of grounding wires is relatively short, usually within tens of minutes, in order to avoid the equipment with grounding wires supplying power, causing related equipment such as tripping, causing serious safety accidents. When installing / removing grounding wires for the same work task, the operation is usually completed within a certain time. Therefore, there is an urgent need for a double-tongue grounding wire working condition intelligent monitoring device that can effectively monitor working conditions such as virtual connection, virtual hanging and missing removal of grounding wires.

BRIEF DESCRIPTION OF THE DRAWINGS

[0007] Figure 1 The present invention is a flowchart of a method for intelligently monitoring the working condition of a double-tongue grounding wire according to a preferred embodiment of the present invention. DETAILED DESCRIPTION

[0008] The technical solution of the present invention is described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0009] Unless otherwise defined, the technical terms or scientific terms used in the present invention shall have the usual meanings understood by persons with ordinary skills in the field to which the present invention belongs. The words "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "one" or "one" do not indicate quantity restrictions, but indicate the existence of at least one. Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship also changes accordingly.

[0010] It is worth pointing out that the grounding wire condition detector (configured by group): each group of smart grounding wires must contain 3 grounding wire hook contact detectors for A / B / C phases, 3 P-phase grounding pile contact detectors, and 1 optional monitoring unit. Grounding wire condition data transmission and monitoring tools (configured by station): each station (or independent work site) contains 1 handheld monitoring terminal and 1 LORA wireless gateway. Because the A / B / C phase detectors and monitoring units of the same group are usually deployed in almost the same geographical location, the error is completely within the allowable range. Therefore, the entire grounding wire system is only equipped with a satellite positioning module in the monitoring unit to identify the geographical location of the smart grounding wire installation. Other detectors are not equipped with satellite positioning modules to reduce the overall cost and reduce the size of the detector.

[0011] The present application provides a double-tongue type grounding wire working condition intelligent monitoring device, comprising: front and rear end detectors, a working dynamic adjustment module, a battery pack remaining power sampling module and a first indicator light trigger button; A monitoring unit, used to monitor the usage signals of the front-end and rear-end detectors in real time, and send the usage signals to the work dynamic adjustment module; The working dynamic adjustment module is used to determine the use status according to the use signal and adjust the working status according to the use status, wherein the use status includes preparation, installation, monitoring, disassembly, and idle; the working status includes state control, sampling frequency, and communication mode; The battery pack remaining power sampling module is used to sample the remaining power of the battery pack according to a set dynamic sampling strategy; and report the sampling result according to a set reporting strategy; The first and second indicator light trigger buttons are used to control the communication mode according to the working status.

[0012] In one example, 15 seconds after the monitoring unit is powered on, the status indicators of the grounding wires of each phase are automatically turned off and the unit enters energy-saving mode, leaving only the communication indicator light intermittently. When the user needs to check the status of the grounding wire, the indicator light button switch is manually triggered once to activate the dormant indicator light, light up all the indicators, and then go back to sleep after 15 seconds.

[0013] The above-mentioned double-tongue type grounding wire working condition intelligent monitoring equipment can intelligently adjust the working state of the monitoring equipment, and can effectively realize the working condition monitoring functions such as grounding wire virtual connection, virtual hanging and missing removal.

[0014] Optionally, it also includes a second indicator light trigger button, and the working dynamic adjustment module determines the use status. When the device is in the installation or disassembly stage, the monitoring unit is controlled to receive the uploaded data of the front and rear detectors in real time, and real-time communication is adopted during the installation. When the intelligent grounding wire is installed, the monitoring unit and the front and rear detectors automatically switch to the non-real-time working mode, and wake up the receiving mode regularly at a preset time interval; During disassembly, after the second indicator light trigger button is triggered, the monitoring unit immediately enters the precise mode of real-time communication and sends a wake-up command to the front and rear end detectors. After receiving the wake-up command, the front and rear end detectors enter the real-time communication mode, and after the set time, if the power is still not cut off, they switch to the energy-saving mode.

[0015] Among them, front-end and back-end detectors refer to the abbreviations of front-end detectors and back-end detectors.

[0016] In this optional implementation, the installation period may refer to the first 10 minutes, which is only an example and not a limitation. By waking up the reception periodically, energy consumption and device power can be saved. The setting time may refer to 10 minutes.

[0017] Optionally, when within a continuous period of time T1, the monitoring unit first receives a first P-phase fixed signal, and then continuously receives the A\B\C three-phase detector changing from open position to closed position, it generates a first usage signal and sends it to the working dynamic adjustment module. The working dynamic adjustment module determines that the usage status is installation based on the first usage signal.

[0018] Among them, the first P-phase fixed signal means that the bolt torque is greater than the threshold. When the A\B\C three-phase detector changes from the open position to the closed position, there is no requirement for the A\B\C phases to follow the sequence.

[0019] Optionally, within a continuous period of time T2, the monitoring unit first receives the signal that the A\B\C three-phase detector changes from the closed position to the open position, and then receives the second P-phase fixed signal, generates a second usage signal and sends it to the working dynamic adjustment module. The working dynamic adjustment module determines that the usage status is disassembly based on the second usage signal.

[0020] Among them, the second P-phase fixed signal means that the bolt torque is less than the threshold. When the A\B\C three-phase detector changes from the open position to the closed position, there is no requirement for the A\B\C phases to follow the sequence.

[0021] Optionally, when the incoming call terminal and the ground terminal are both in a reliable connection state and are maintained for a period of time T3, the monitoring unit generates a third use signal and sends it to the work dynamic adjustment module, and the work dynamic adjustment module determines that the use state is monitoring according to the third use signal; When the device is in monitoring use, the monitoring unit adopts a periodic sleep mode. When new data is identified or the interval collection time is reached, the monitoring unit wakes up and performs corresponding processing; if the interval collection time has not arrived, it continues to sleep and repeats in sequence.

[0022] In this optional implementation, the monitoring device can monitor network signals with extremely low power consumption in the sleep state, so that the wake-up and sleep states of the monitoring device can be controlled according to the periodic cycle or the received wake-up instruction, thereby achieving a low power consumption effect.

[0023] Alternatively, in other feasible implementations, a wake-up button may be provided on the monitoring device, and a manual wake-up mode may be adopted through the wake-up button to facilitate operation and maintenance personnel to timely check the real-time working condition of the device.

[0024] Optionally, when the incoming call end is in an unhooked state and the grounding end bolt is loosened, the monitoring unit generates a fourth usage signal and sends it to the work dynamic adjustment module. The work dynamic adjustment module determines that the usage state is idle based on the fourth usage signal.

[0025] In one example, in the installation and disassembly use states, the monitoring device samples the ground wire clamping working condition mode at a high frequency; after entering the monitoring use state, the front and rear detectors and the monitoring unit enter the real-time sampling ground wire clamping working condition mode; after entering the monitoring use state, the monitoring device samples the ground wire clamping working condition mode at a first set frequency; when entering the idle use state, only the device remains powered on, and the monitoring device samples the ground wire clamping working condition mode through the sensor at a second set frequency, and the second set frequency is lower than the first set frequency. In one example, the first set frequency can be 30 minutes / time, and the second set frequency can be a frequency lower than 30 minutes / time. This is only an example and is not limited.

[0026] Optionally, when the detector attachment state does not change for 10 minutes, the dynamic sampling strategy is set as follows: When the remaining power of the battery pack of the detector and monitoring unit is greater than or equal to 15%, sampling is performed at 900 seconds per time and compared with the last recorded historical status; monitor the operating condition data reported by the front-end sensor in the same group and compare it with the last recorded historical status.

[0027] In this way, by dynamically selecting different sampling frequencies, while meeting the actual needs of monitoring the grounding wire conditions, the power consumption required for the device sampling work and the signal wireless signal transmission power consumption can be reduced, effectively extending the battery pack power supply time.

[0028] When the remaining power of the battery pack of the detector or monitoring unit is less than 15%, press 300 seconds / time and compare it with the last recorded historical status; The setting reporting strategy is as follows: If the working condition or remaining power condition of any front-end sensor changes, the changed status information will be immediately reported to the LORA gateway and portable monitoring terminal; if the remaining power does not change, the remaining power data of each sensor battery pack will be reported to the LORA gateway and portable monitoring terminal every 90 seconds.

[0029] It is worth pointing out that the battery pack usually provides power for several days to several months. The current device uses a fixed time interval to sample the remaining power of the battery pack. Before the power is higher than 15%, it will not affect the normal operation of the device, but it obviously wastes some power. Therefore, the sampling interval of the remaining power during this period can be enlarged to save limited power. When the power is lower than 15%, it indicates that the power of the device is about to run out. During this period, the user needs to be constantly reminded to pay attention to the remaining power of the device. Therefore, shortening the sampling time interval is more conducive to users to better monitor the working conditions of the grounding wire.

[0030] Optionally, a detector equipped with a single photoelectric sensor is selected for the location to be installed where the curvature of the conductor is small, and a detector equipped with a double photoelectric sensor is selected for the location to be installed where the curvature of the conductor is large.

[0031] In this way, the double-tongue grounding wire working condition detector is configured with single / double photoelectric sensors. For the installation site with small curvature of the conductor (relatively horizontal), a detector with a single photoelectric sensor is selected to increase the continuous power supply time of the detector battery pack; for the installation site with large curvature of the conductor, a double photoelectric sensor is selected to monitor the clamping condition of the detector and the conductor on both sides, which effectively solves the pain point problem of "virtual hanging" on one side when the "double-tongue" hook is installed at the installation site with large curvature. Specifically, a small curvature of the conductor refers to less than the first set degree, wherein the first set degree is 30°, and a large curvature of the conductor refers to greater than the first set degree and less than the second set degree, wherein the second set degree is 45°.

[0032] It is worth pointing out that different LoRa modules with different transmission powers are used for different installation spacings of smart grounding wires of different group numbers. The transmission current of low-power LoRa modules is ≤125mA (maximum transmission power configuration), and the transmission current of high-power LoRa modules is ≤1000mA (maximum transmission power configuration). When the installation spacing is less than 1km (such as substation use), a low-power wireless module is selected; when the installation spacing is greater than 1km but less than 5km (such as transmission lines), a high-power wireless communication module is selected.

[0033] In this way, the continuous power supply time and effective wireless transmission distance of the device are taken into account. The effective transmission distance of the low-power LoRa module is usually around 1kM, and the effective transmission distance of the high-power LoRa module is usually around 5kM; at the same time, the transmission current of the low-power LoRa module is smaller than that of the high-power LoRa module, resulting in a relatively small amount of power required during the operation of the low-power LoRa module, which will help to extend the power supply time of the battery pack of the device. Therefore, under the condition of meeting the transmission distance, the selection of a low-power LoRa module can reduce the power consumption of the entire device and extend the power supply time of the battery pack.

[0034] Below, several application scenarios are used to illustrate the sampling and data reporting strategies of the sensor / monitoring unit of the above-mentioned double-tongue grounding wire working condition intelligent monitoring device.

[0035] 1. Detector 1. Scenario 1 is set as the installation phase: the status of the laser hook node (or spiral pressure sensor node) of the front and rear detectors changes; (1) The sampling strategy is: the A / B / C hook detector samples the laser sensor working condition (or spiral pressure sensor node) and the battery pack remaining power condition in real-time mode.

[0036] (2) The upload strategy is: report the collected data to the monitoring unit of this group in real time. [Enter real-time communication mode] 2. Scenario 2 is set to the detector attachment state after 10 minutes without change: (1) The sampling strategy is as follows: the A / B / C hook detector samples the laser sensor working condition (or spiral pressure sensor node) at a frequency of 30 seconds / time, and samples the remaining power of the battery pack at a frequency of 900 seconds / time, and compares it with the last recorded historical status.

[0037] (2) The upload strategy is: after comparison, if the status of the sensor detector changes, the changed status information will be immediately reported to the monitoring unit; if the status of the sensor detector does not change, each sensor will regularly report its current operating condition and remaining battery power to the monitoring unit of the group at a frequency of 1800 seconds / time (30 minutes) to ensure that the monitoring unit obtains the latest operating condition data (similar to a general call command).

[0038] 3. Scenario 3 is set to monitor the communication link between the front-end and back-end detectors and the monitoring unit (heartbeat monitoring): (1) Data transmission strategy If the front-end sensor does not detect a status change within 10 minutes, it will upload a heartbeat message every 30 minutes.

[0039] The communication interruption judgment strategy (two conditions and gate) is: ① The monitoring unit does not receive the heartbeat message from the front-end and back-end detectors (laser hook node or spiral pressure sensor node) within 30 minutes; ② The monitoring unit does not receive the working condition and remaining power data of the sensor; When both conditions are met at the same time, it is judged that the communication between the detector (such as phase A detector) and the monitoring unit is interrupted, and the alarm signal is uploaded to the gateway or portable monitoring terminal.

[0040] (3) The communication recovery judgment strategy (two conditions or gates) is as follows: ① The monitoring unit receives a detector change signal (such as the A-phase detector) within the next heartbeat monitoring cycle (i.e., before 30 minutes), and the corresponding status indicator of the monitoring unit also changes accordingly (the "communication light" is green, and the "A-phase" is green); ② The monitoring unit receives the heartbeat signal. When any of the above two conditions is met, it is judged that the communication between the detector (such as the A-phase detector) and the monitoring unit has been restored, and the alarm signal is uploaded to the gateway or portable monitoring terminal, and the corresponding status indicator of the monitoring unit detector changes accordingly (the "communication light" is green, and the "A-phase" is green).

[0041] 2. Monitoring unit 1. Scenario 4 is set to the detector (laser sensor or pressure sensor) working state changes: (1) The sampling strategy is: in real-time sampling mode, the pressure sensor working condition and the battery pack remaining power working condition are adopted; (2) The upload strategy is: report the collected data to the LORA gateway and portable monitoring terminal in real time. [Enter real-time communication mode] 2. Scene 5 is set to the detector attachment state after 10 minutes without change: (1) The sampling strategy is: the P-phase detector samples the working condition of the pressure sensor at a frequency of 30 seconds / time, and samples the remaining power of the battery pack at a frequency of 1200 seconds / time, and compares it with the last recorded historical state. Monitor the working condition data reported by the front-end sensors in the same group and compare it with the last recorded historical state.

[0042] (2) The upload strategy is: if the working condition or remaining power condition of any front-end sensor changes, the changed status information will be immediately reported to the LoRa gateway and portable monitoring terminal; if the sensor working condition or remaining power does not change, the current working condition data of each sensor and the remaining power data of the battery pack will be reported to the LoRa gateway and portable monitoring terminal at 1800 seconds / time (30 minutes).

[0043] 3. Scenario 6 is set to monitor the communication link (heartbeat monitoring) between the monitoring unit and the gateway (or monitoring terminal) [to solve the problem that after the monitoring unit is powered off midway, the front and back detectors are powered on, but after the position condition signal changes, the monitoring unit cannot change in time] (1) The data sending strategy is as follows: If the front-end sensor does not detect a status change within 10 minutes, it will upload a heartbeat message every 30 minutes. Communication interruption judgment strategy (two conditional AND gates): ① The monitoring unit has not received the heartbeat message from the front-end and back-end detectors within 30 minutes; ② The monitoring unit has not received the working condition and remaining power data of the sensor; When the above two conditions are met at the same time, it is judged that the communication between the detector (such as the A-phase detector) and the monitoring unit is interrupted, and the alarm signal is uploaded to the gateway or portable monitoring terminal, and the corresponding status indicator light of the monitoring unit detector changes accordingly (the "communication light" is yellow, and the "A-phase" is yellow); Communication recovery judgment strategy (two conditions or gates): ① The monitoring unit receives a detector change signal (such as the A-phase detector) within the next heartbeat monitoring cycle (i.e., within 30 minutes), and the corresponding status indicator of the monitoring unit also changes accordingly (the "communication light" is green, and the "A-phase" is green); ② The monitoring unit receives a heartbeat signal. When any of the above two conditions is met, it is judged that the communication between the detector (such as the A-phase detector) and the monitoring unit is restored, and the alarm signal is uploaded to the gateway or portable monitoring terminal, and the corresponding status indicator of the monitoring unit detector changes accordingly (the "communication light" is green, and the "A-phase" is green).
