Description

Technical Field

[0001] The present invention relates to the field of power monitoring, and in particular to a management method for power monitoring equipment. Background Art

[0002] In the current power monitoring field, the independent deployment of high-performance single devices is still the mainstream application scenario. If power monitoring wants to achieve 360-degree all-round monitoring without blind spots, the required monitoring equipment must be equipped with a pan / tilt and multiple cameras to meet the requirements. The cost of monitoring equipment that can usually meet these requirements is relatively high. Moreover, due to structural limitations, the multiple cameras of the above monitoring equipment are basically concentrated in a very small structural range, and the span is generally no more than 20CM. Figure 1 As shown, a power tower equipped with the above-mentioned monitoring equipment can basically realize all-round monitoring of a fixed installation location.

[0003] In some special power monitoring scenarios, such as power towers in forest areas, the monitoring equipment installed at the highest position can achieve all-round monitoring in a fixed position, but it can only monitor information above the forest area. Due to the canopy obstruction, the view in the forest area requires a monitoring device at a lower position. However, if multiple monitoring devices are installed at multiple locations to achieve all-round monitoring, the equipment cost and maintenance cost will be very high. Summary of the invention

[0053] Figure 2 A flow chart of a method for managing a power monitoring device according to the present invention;

[0054] Figure 3 It is a schematic diagram of the structural modules of the power monitoring device of the present invention. DETAILED DESCRIPTION

[0055] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0056] The present invention provides a management method for power monitoring equipment, such as Figure 1-3 As shown, there are multiple power monitoring devices 1, and the multiple power monitoring devices 1 include a main monitoring device 2 and at least one auxiliary monitoring device 3. The main monitoring device 2 and the auxiliary monitoring device 3 are installed at multiple locations of the tower 4 to achieve all-round monitoring.

[0057] The main monitoring device 2 is connected to each secondary monitoring device 3 LAN through a wireless ad hoc network to exchange commands, and the control commands are transmitted using the wireless ad hoc network protocol. The wireless ad hoc network can be a Bluetooth connection, a long-range radio (Long Range Radio, Lora) connection, etc., and the present invention does not limit this.

[0058] The main monitoring device 2 is connected to the cloud server 5 via a wide area network, such as 4G (fourth generation mobile communication technology), 5G (fifth generation mobile communication technology) and other networks. The main monitoring device 2 is equipped with a SIM (Subscriber Identity Module) card and connected to the cloud server 5, while the secondary monitoring device 3 is not equipped with a SIM card. All maintenance data is exchanged between the main monitoring device 2 and the cloud server 5.

[0059] The management method is as Figure 2 As shown, including:

[0060] S1: The primary monitoring device initiates a connection service and waits for the secondary monitoring device to connect.

[0061] S2: After the secondary monitoring device finds the primary monitoring device, it binds to the primary monitoring device and replies the binding status to the primary monitoring device.

[0062] S3: The primary monitoring device adds the secondary monitoring device to the maintenance list according to the received binding status.

[0063] S4: After binding, the main monitoring device sends control instructions to the secondary monitoring device as needed, and the secondary monitoring device performs corresponding tasks according to the received control instructions.

[0064] After binding, various commands of the main monitoring device and the secondary monitoring device interact through the wireless ad hoc network. The main monitoring device controls the secondary monitoring device through the control protocol to perform time calibration, photo taking, OTA (Over-the-Air Technology) upgrades, basic information acquisition, etc. Because it is an internal interaction within the LAN and is not connected to the WAN, it does not consume additional traffic. Taking the main monitoring device sending control commands to the secondary monitoring device as an example, the secondary monitoring device continuously monitors control commands, including photo taking commands, upgrade commands, unbinding commands, and time calibration commands. When the secondary monitoring device monitors the control command, it executes the corresponding task (such as taking pictures, upgrading, unbinding, time calibration, etc.), and replies to the main monitoring device with relevant commands for command interaction.

[0065] The present invention realizes one-to-many monitoring deployment by setting up a main monitoring device and a sub-monitoring device, by expanding the capabilities of the main monitoring device, in the form of a main monitoring device with sub-monitoring devices. The main monitoring device and the sub-monitoring device discover the device and establish a communication connection through a wireless ad hoc network protocol, and the main monitoring device uniformly maintains and manages the communication with each sub-monitoring device. The main monitoring device is connected to the cloud server through a wide area network, and all maintenance data is interacted with the cloud server through the main monitoring device. The present invention uniformly manages and maintains the sub-monitoring devices through the main monitoring device, saving equipment costs and operating costs.

[0066] When the wireless ad hoc network mode is Bluetooth connection, the aforementioned S1 includes: the main monitoring device starts Bluetooth and sets the Bluetooth name (exemplarily, the Bluetooth name starts with XXYY_), initiates a connection service, and waits for the secondary monitoring device to connect.

[0067] Accordingly, S2 includes:

[0068] S21: The secondary monitoring device starts Bluetooth, searches for the Bluetooth of the primary monitoring device according to the Bluetooth name (ie searches for the Bluetooth beginning with XXYY_), and initiates pairing.

[0069] S22: Determine whether pairing is successful. If so, execute S23. Otherwise, return to S21 to search for the Bluetooth of the main monitoring device according to the Bluetooth name, initiate pairing, and search for Bluetooth again.

[0070] S23: Determine whether the secondary monitoring device is bound to the primary monitoring device. If not, bind it to the primary monitoring device and reply the binding status to the primary monitoring device. If yes, do not bind it.

[0071] As an improvement, in order to maintain the connection between the primary and secondary monitoring devices, the method further includes:

[0072] S5: The primary monitoring device periodically sends a first heartbeat instruction to the secondary monitoring devices in the maintenance list.

[0073] S6: The secondary monitoring device listens to the first heartbeat instruction. When the first heartbeat instruction is heard within the set first time threshold (for example, N minutes), it replies with the first heartbeat reply instruction to the main monitoring device. Otherwise, it returns to search for the Bluetooth of the main monitoring device according to the Bluetooth name, initiates the pairing step, and re-binds with the main monitoring device.

[0074] S7: Determine whether the primary monitoring device receives the first heartbeat reply instruction within the set second time threshold (for example, 10 minutes). If so, do not process it; otherwise, remove the secondary monitoring device from the maintenance list.

[0075] Accordingly, the aforementioned S4 includes:

[0076] S41: The main monitoring device sends a control instruction to the secondary monitoring device.

[0077] S42: After receiving the control instruction, the secondary monitoring device determines whether the control instruction is an unbinding instruction. If so, execute S43; otherwise, the secondary monitoring device executes the control instruction.

[0078] S43: The secondary monitoring device is unbound from the current primary monitoring device, and searches for the Bluetooth of the new primary monitoring device according to the Bluetooth name based on the serial number of the new primary monitoring device to be bound contained in the unbinding instruction, initiates pairing, and binds to the new primary monitoring device.

[0079] S44: When the secondary monitoring device is successfully unbound from the current primary monitoring device, a successful unbinding instruction is sent to the current primary monitoring device. After receiving the successful unbinding instruction, the current primary monitoring device removes the secondary monitoring device from the maintenance list.

[0080] The unbinding command is used to solve the problem that the secondary monitoring device is incorrectly bound to the main monitoring device of the adjacent tower during the networking process. The unbinding command is used to unbind and rebind.

[0081] When the wireless ad hoc network mode is a long-distance radio connection, the aforementioned S1 includes: the main monitoring device initiates a connection service and sends a second heartbeat instruction at a fixed time, wherein the second heartbeat instruction includes a common heartbeat instruction and a special heartbeat instruction.

[0082] Accordingly, the S2 includes:

[0083] S21': The secondary monitoring device monitors the second heartbeat instruction. When the second heartbeat instruction is monitored, it determines whether the second heartbeat instruction includes the IMEI (International Mobile Equipment Identity) number of the secondary monitoring device. If so, it is a special heartbeat instruction. At this time, the secondary monitoring device is unbound from the current main monitoring device, and returns to S21' to rebind the new main monitoring device. Otherwise, it is a normal heartbeat instruction and executes S22'.

[0084] The special heartbeat is used to solve the problem that the secondary monitoring device is incorrectly bound to the primary monitoring device of the adjacent tower during the networking process. The unbinding command is used to unbind and rebind the secondary monitoring device.

[0085] S22': Determine whether the secondary monitoring device is bound to the primary monitoring device. If not, bind it to the primary monitoring device and reply the binding status to the primary monitoring device. If yes, execute S23'.

[0086] S23': The secondary monitoring device replies with a second heartbeat reply instruction to the primary monitoring device to maintain the connection between the primary and secondary monitoring devices. The primary monitoring device determines whether the second heartbeat reply instruction is received within the set third time threshold. If so, no processing is performed; otherwise, the secondary monitoring device is removed from the maintenance list.

[0087] As an improvement, the method includes:

[0088] S5': After binding, when the secondary monitoring device does not monitor the second heartbeat instruction within the set fourth time threshold, the secondary monitoring device is unbound from the primary monitoring device, and returns to S21' to re-bind.

[0089] In the present invention, the main monitoring device and the secondary monitoring device are connected via WiFi (WIreless Fidelity), and the transmission of large amounts of data is carried out using WiFi communication, such as when the secondary monitoring device takes a photo and transmits it back and when the secondary monitoring device downloads an upgrade package. In such scenarios, the main monitoring device detects that the execution of the current control instruction requires the transmission of a large amount of data, and then turns on WiFi communication. The specific method is as follows:

[0090] S100: When the main monitoring device and / or the secondary monitoring device need to be upgraded, the main monitoring device downloads the upgrade package from the cloud server via the wide area network.

[0091] Exemplarily, the upgrade package is an OTA upgrade package. When an upgrade is required, the cloud server pushes the upgrade information and upgrade package to the main monitoring device, and the main monitoring device downloads the OTA upgrade package.

[0092] S110: Determine whether the upgrade package is for the main monitoring device or the secondary monitoring device. If it is for the main monitoring device, the main monitoring device is upgraded according to the upgrade package, and the main monitoring device is restarted after the upgrade is successful. If it is for the secondary monitoring device, execute S12.

[0093] S120: The main monitoring device turns on the WiFi hotspot and the FTP server, and sends an upgrade instruction to the secondary monitoring device, where the upgrade instruction includes information about the WiFi hotspot.

[0094] S130: After receiving the upgrade instruction, the secondary monitoring device connects to the WiFi hotspot of the primary monitoring device according to the WiFi hotspot information contained in the upgrade instruction. After the WiFi is connected, the secondary monitoring device accesses the FTP server to download the upgrade package.

[0095] S140: After the secondary monitoring device has downloaded the upgrade package, it sends a download completion instruction to the primary monitoring device and performs an upgrade according to the upgrade package. The secondary monitoring device restarts after the upgrade is successful.

[0096] S150: After receiving the download completion instruction, the main monitoring device turns off the WiFi hotspot and the FTP (File Transfer Protocol) server to save energy consumption of the main monitoring device.

[0097] In the present invention, the upgrade is uniformly managed by the main monitoring device, and the main monitoring device is upgraded autonomously. When upgrading the secondary monitoring device, the secondary monitoring device autonomously downloads the upgrade package through the WiFi hotspot of the main monitoring device for upgrading. Because WiFi is a local area network connection between the main monitoring device and the secondary monitoring device, and is not connected to the wide area network, the secondary monitoring device does not consume additional traffic when downloading the upgrade package.

[0098] As an improvement, the method of the present invention further comprises:

[0099] S200: When the secondary monitoring device needs to take a photo, the primary monitoring device turns on the WiFi hotspot and the FTP server, and sends a photo-taking instruction to the secondary monitoring device, where the photo-taking instruction includes information about the WiFi hotspot.

[0100] Whether to take a photo can be determined based on the command or message sent by the cloud server to the main monitoring device. The main monitoring device determines whether to take a photo based on the command or message sent. When the secondary monitoring device is required to take a photo, this step is executed. When the main monitoring device is required to take a photo, the main monitoring device can directly take photos according to the required photo time.

[0101] S210: After receiving the photo-taking instruction, the secondary monitoring device takes a photo at a scheduled time according to the required photo-taking time, and connects to the WiFi hotspot of the primary monitoring device according to the WiFi hotspot information contained in the photo-taking instruction to access the FTP server.

[0102] S220: The secondary monitoring device uploads the captured photos to the primary monitoring device via the WiFi hotspot and FTP service.

[0103] Because WiFi is a local area network connection between the main monitoring device and the secondary monitoring device and is not connected to the wide area network, uploading photos to the secondary monitoring device does not consume additional traffic.

[0104] S230: After receiving the uploaded photos, the main monitoring device turns off the WiFi hotspot and the FTP server to save energy consumption of the main monitoring device.

[0105] The main monitoring device of the present invention also has a log uploading function to the cloud server. The log uploading can be executed according to the instruction issued by the cloud server, or it can be automatically executed according to the timing of the main monitoring device.

[0106] In the present invention, the main monitoring device performs time calibration through the cloud server, and the secondary monitoring device performs time calibration based on the main monitoring device through the control protocol. During time calibration, the main monitoring device sends a time calibration instruction to the secondary monitoring device, and the secondary monitoring device performs time calibration after receiving the time calibration instruction, resets the alarm clock, and performs timed tasks to ensure its normal operation.

[0107] In the present invention, the main monitoring device and the auxiliary monitoring device can be configured equally, or the main monitoring device can be configured higher than the auxiliary monitoring device. The high configuration of the main monitoring device and the low configuration of the auxiliary monitoring device can save costs. The main and auxiliary monitoring devices can be freely combined. For example, if a secondary monitoring device in a certain network fails, it can be immediately replaced without affecting the remaining auxiliary monitoring devices. If the main monitoring device breaks down, after replacing the new main monitoring device, the remaining auxiliary monitoring devices can automatically re-network and continue to work. The main and auxiliary monitoring devices are flexibly matched to meet diversified monitoring scenarios and save operating costs at the same time.

[0108] After the main and auxiliary monitoring devices are connected through a self-organizing network, the heartbeat and control instructions are sent through the corresponding wireless protocol (Bluetooth or Lora, etc.); the main monitoring device receives the photo information of the auxiliary monitoring device and the auxiliary monitoring device downloads the OTA package through the main monitoring device through the WIFI hotspot of the main monitoring device and the built-in FTP service, so as to realize the large data transmission between the main and auxiliary monitoring devices. In this implementation mode, the daily signaling interaction between the main and auxiliary monitoring devices, photo transmission, and OTA download of the auxiliary monitoring device will not consume additional traffic, which greatly saves the operating cost.

[0109] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
