[0042] First, it should be noted that the terms used in the embodiments of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. As used in the embodiments of the present invention and the appended claims, the singular forms "a," "the," and "the" are intended to include the plural forms, unless the context clearly indicates otherwise.

[0043] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Therefore, it should be recognized by those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0044] It should be noted that in other embodiments, the steps of the corresponding method are not necessarily performed in the order shown and described in this specification. In some other embodiments, the method may include more or fewer steps than those described in this specification. In addition, a single step described in this specification may be broken down into multiple steps for description in other embodiments, and multiple steps described in this specification may be combined into a single step for description in other embodiments.

[0045] The following will further explain in detail the smart construction site equipment operation and maintenance management method and system described in the embodiments of this specification in combination with the drawings and specific embodiments of the specification, but this detailed description does not constitute a limitation on the embodiments of this specification.

[0046] Please refer to Figure 1 , Figure 1 A flowchart illustrating a method for smart construction site equipment operation and maintenance management is provided. This method is applicable to a smart construction site equipment operation and maintenance management system, which includes a management platform, an operation and maintenance router, an operation and maintenance module, and target devices. The operation and maintenance router is powered by a power supply (on a construction site, this power supply typically refers to a distribution box) and provides network access for one or more connected target devices. Furthermore, the operation and maintenance router can collect the connection status of its connected target devices in real time and upload it to the management platform. This connection status includes both online and offline status. The operation and maintenance module is connected to the power supply and is simultaneously connected to one or more target devices. The operation and maintenance module can function as a data acquisition module, collecting operating status data from its connected target devices and uploading it to the management platform via a built-in network module. Furthermore, the operation and maintenance module can function as a power switch, controlling the on / off switching of the power supply circuit between the connected target device and the power supply. Furthermore, the operation and maintenance module can function as a reverse controller, performing reverse control of its connected target devices under remote control from the management platform.

[0047] The target devices mentioned above refer to smart construction site equipment deployed on the construction site that need to access the network for data transmission or remote control, such as sensors (temperature, humidity, pressure sensors, etc.), cameras, fog cannons, enclosure spray equipment, distribution box electronic locks, etc.

[0048] like Figure 1 As shown, the above-mentioned smart construction site equipment operation and maintenance management method includes steps S100 to S110.

[0049] S100: collects the connection status of the target device to which it is connected through the operation and maintenance router and uploads it to the management platform.

[0050] Since the target device needs to register its physical address when joining the network, the operation and maintenance router can uniquely identify the connected target device by its physical address and collect the connection status of the connected target device and upload it to the management platform. The connection status of the target device mentioned above includes online status and offline status.

[0051] It should be noted that the number of operation and maintenance routers can be based on the required equipment, and this embodiment does not limit this. In addition, each operation and maintenance router can be connected to one or more target devices, and this embodiment does not limit this either.

[0052] In some implementations, a whitelist can be set up on the operation and maintenance router to control access to legitimate devices. The operation and maintenance router then manages network access based on the whitelist, allowing only devices on the whitelist to access the network while excluding all other devices. This allows for control over the devices connected to the operation and maintenance router, preventing other unauthorized devices from accessing the site, which could occupy network resources and affect the data transmission rate of smart construction site equipment.

[0053] S102: The operation status of the target device to which it is connected is collected through the operation and maintenance module, and uploaded to the management platform.

[0054] The operation and maintenance module can collect the operating status data of the target device connected to it via the bus. The bus protocol used by the operation and maintenance module can be set as needed, and this embodiment does not impose any restrictions on this. For example, the operation and maintenance module can communicate with the target device connected to it via the RS485 bus protocol to collect the operating status data of the target device connected to it.

[0055] In addition, the operation and maintenance module can also monitor the status data of the power supply to which it is connected. In some embodiments, a backup power supply can be provided within the operation and maintenance module. When the power supply to which the operation and maintenance module is connected loses power, the operation and maintenance module activates the backup power supply to power itself and uploads power failure information to the management platform.

[0056] It should be noted that the backup power supply and its working mode can be implemented using any existing technology that can achieve the same technical effect. This embodiment does not limit this and will not be described in detail.

[0057] S104: Regularly restart the operation and maintenance modules one by one through the management platform according to the preset inspection sequence, so that the target devices connected to the operation and maintenance modules are powered off during the shutdown period of the operation and maintenance modules, and obtain the target device connection status change data uploaded by the operation and maintenance router during the shutdown period of each operation and maintenance module.

[0058] Construction site scenarios are different from conventional business scenarios. As the construction progresses, the location and connection relationship of smart construction site equipment often change, which makes it difficult to quickly and accurately locate the fault when a fault occurs.

[0059] In view of this, this step provides a solution for real-time updating of the global circuit topology and the global network topology for this situation.

[0060] Specifically, for each construction site, the management platform can number the operation and maintenance modules deployed at the construction site, set the inspection order according to the number sequence (for example, inspections are carried out in ascending order of numbers), and then restart the operation and maintenance modules in the construction site one by one according to the inspection order. Restarting one by one means turning off and then turning on the first operation and maintenance module in the inspection order, and then turning off and then turning on the second operation and maintenance module, ensuring that only one operation and maintenance module is turned off at a time, and so on, until the restart step is performed on all operation and maintenance modules in the construction site. When the operation and maintenance module is turned off, the power supply circuit of the target device to which it is connected will be cut off, causing the target device to which it is connected to lose power.

[0061] In some implementations, a relay may be provided in the operation and maintenance module. After the management platform sends a restart instruction to the operation and maintenance module, the operation and maintenance module controls the relay to disconnect and then connect the operation and maintenance module from the power supply according to the restart instruction.

[0062] Obviously, when an operation and maintenance module is disconnected, the target devices connected to it will go offline due to power outage. A disconnection refers to a target device going offline from online. At this point, the target device connection status data uploaded by the corresponding operation and maintenance router will change. This target device connection status change data contains information about the target devices that went offline during the period when the operation and maintenance module was disconnected.

[0063] It should be noted that in this step, the management platform can implement the above-mentioned inspection process according to a pre-set inspection cycle. Generally speaking, the management platform can implement the above-mentioned inspection process during construction breaks, such as at night. The inspection cycle and the time point at which the inspection is implemented by the management platform can be set according to needs and are not limited in this embodiment.

[0064] S106: Determine the local circuit topology of the target device connected to the operation and maintenance module and the local network topology of the target device connected to the operation and maintenance router based on the target device connection state change data.

[0065] The operation and maintenance router can only obtain the target devices it is connected to and the connection status of these target devices, but cannot obtain the topology of the target devices it is connected to.

[0066] For this reason, this step needs to use the target device connection status change data obtained by the operation and maintenance router during the inspection process to determine the local circuit topology of the target device connected to the operation and maintenance module and the local network topology of the target device connected to the operation and maintenance router.

[0067] First, we'll describe the method for constructing the local circuit topology for the target devices connected to the O&M modules. For each O&M module, when that module disconnects, the offline target devices are added to that module's associated device set. If the associated device sets of two O&M modules intersect, the devices in the intersection are removed from the associated device set of the first O&M module to be restarted, following the inspection order. After the inspection is complete, the local circuit topology for the target devices connected to each O&M module is constructed based on its associated device set.

[0068] Please refer to Figure 3 , Figure 3 FIG1 shows a target device topology diagram in an implementation scenario. Figure 3 As shown, the operation and maintenance module 1 is connected to camera 1, camera 2 and the bridge, that is, the operation and maintenance module 1 supplies power to camera 1, camera 2 and the bridge. The operation and maintenance module 2 is connected to camera 3, that is, the operation and maintenance module 2 supplies power to camera 3. There is a direct network connection between camera 1, camera 2 and the operation and maintenance router, while camera 3 is connected to the operation and maintenance router via a bridge, that is, there is an indirect network connection between camera 3 and the operation and maintenance router. It should be noted that in order to simplify the drawings, Figure 3 The power supply is not shown.

[0069] by Figure 3The topology shown in FIG2 is used as an example to illustrate the process of constructing the local circuit topology of the target device connected to the operation and maintenance module. According to the inspection order, the management platform first controls the operation and maintenance module 1 to restart, that is, controls the operation and maintenance module 1 to disconnect and then connect. When the operation and maintenance module 1 is disconnected, the operation and maintenance router will detect that camera 1, camera 2, camera 3 and the bridge are offline. At this time, camera 1, camera 2, camera 3 and the bridge are included in the associated device set of the operation and maintenance module 1. Next, the management platform controls the operation and maintenance module 2 to restart, that is, controls the operation and maintenance module 2 to disconnect and then connect. When the operation and maintenance module 2 is disconnected, the operation and maintenance router will detect that camera 3 is offline. At this time, camera 3 is included in the associated device set of the operation and maintenance module 2. Obviously, at this time, the associated device set of the operation and maintenance module 1 and the associated device set of the operation and maintenance module 2 have an intersection, that is, camera 3. According to the inspection order, O&M module 1 restarts first, so camera 3 is removed from O&M module 1's associated device set. The resulting associated device set for O&M module 1 is {camera 1, camera 2, bridge}, and the associated device set for O&M module 2 is {camera 3}. Because the target devices in an O&M module's associated device set are directly connected to that module, the local circuit topology of the target devices connected to each O&M module can be determined.

[0070] Next, a method for constructing the local network topology of the target devices connected to the operation and maintenance router is introduced. For each operation and maintenance router, the set of target devices connected to it is obtained. If the target device connected to the operation and maintenance router is disconnected only once during the inspection process, it is determined that the corresponding target device is directly connected to the operation and maintenance router. If the target device connected to the operation and maintenance router is disconnected more than once during the inspection process, it is determined that the corresponding target device is indirectly connected to the operation and maintenance router, and by finding the disconnection status of the relay device or bridge to which the operation and maintenance router is connected when the corresponding target device is disconnected, the connection relationship between the corresponding target device and the corresponding relay device or bridge is determined, and finally the local network topology of the target device connected to the operation and maintenance router is obtained.

[0071] Continue with Figure 3Taking the topology shown as an example, the set of target devices connected to the operation and maintenance router is {camera 1, camera 2, camera 3, bridge}. During the inspection process, camera 1, camera 2, and the bridge each experienced only one disconnection. Therefore, it can be determined that cameras 1, camera 2, and the bridge are directly connected to the operation and maintenance router. Direct connection here refers to a direct network connection. However, camera 3 experienced two disconnections during the inspection process. Therefore, it can be determined that the connection between camera 3 and the operation and maintenance router is indirect, that is, the connection between camera 3 and the operation and maintenance router is through a bridge or relay device. At this time, checking the disconnection status of other devices when camera 3 went offline, it was found that the bridge and camera 3 went offline at the same time (the bridge also went offline when camera 3 went offline for the first time). At this time, it is determined that camera 3 is connected to the operation and maintenance router through the bridge. Finally, the local network topology of the target devices connected to the operation and maintenance router is obtained.

[0072] S108: Constructing a global circuit topology based on the local circuit topology, and constructing a global network topology based on the local network topology.

[0073] After step S106 , the local network topology of the target device connected to each operation and maintenance router and the local circuit topology of the target device connected to each operation and maintenance module can be obtained.

[0074] The local circuit topology of the target device connected to the operation and maintenance module is spliced ​​to obtain the corresponding global circuit topology.

[0075] The local network topology of the target device connected to the operation and maintenance router is spliced ​​to obtain the corresponding global network topology.

[0076] S110: When the management platform detects that the connection status of the target device is offline or the operation status of the target device is abnormal, the faulty device is located based on the global circuit topology and the global network topology.

[0077] The management platform can monitor the connection status and operating status of the acquired target devices. When one or more target devices are found to be offline or operating abnormally, the faulty devices can be located based on the global circuit topology and global network topology.

[0078] It should be noted that the above method of judging whether the operating status of the target device is abnormal can be set according to needs. For example, rule matching or threshold matching can be used to determine whether the operating status of the target device is abnormal. This embodiment does not limit this.

[0079] S112: The management platform executes a preset fault response strategy according to the fault location result.

[0080] Common faults can usually be resolved by restarting the device. Therefore, in this step, after locating the faulty device, the management platform can use the fault location results to search the global circuit topology and restart the faulty branch circuit using the corresponding operation and maintenance module. If the faulty device resumes operation after restarting the faulty branch circuit, the fault response strategy is executed and the fault log is recorded and pushed to the operation and maintenance personnel. Otherwise, the fault location results are sent to the operation and maintenance personnel, who are notified to perform on-site maintenance.

[0081] In some cases, some target devices can resume working after restarting. In this case, there is no need for operation and maintenance personnel to go to the site for maintenance. They only need to remotely restart these target devices through the management platform.

[0082] For target devices that still cannot resume working after restarting, it is necessary to notify the operation and maintenance personnel to come to the site for maintenance. At this time, the location results of the faulty device need to be sent to the operation and maintenance personnel to help them quickly find the faulty device when they arrive at the site, saving the time and cost of manual troubleshooting.

[0083] Corresponding to the target equipment operation and maintenance management method, this embodiment also provides a smart construction site equipment operation and maintenance management system, which is used to implement the smart construction site equipment operation and maintenance management method. Figure 2 The system includes: a management platform, an operation and maintenance router, an operation and maintenance module and a target device. The operation and maintenance router is powered by a power supply (on a construction site, the power supply usually refers to a distribution box) and provides network access for one or more target devices to which it is connected. At the same time, the operation and maintenance router can collect the connection status of the target device to which it is connected in real time and upload it to the management platform. The connection status includes online status and offline status. The operation and maintenance module is connected to the power supply and is connected to one or more target devices at the same time. On the one hand, the operation and maintenance module can serve as a data acquisition module to collect the operating status data of the target device to which it is connected and upload it to the management platform through the built-in network module; on the other hand, the operation and maintenance module can serve as a power switch to control the on-off of the power supply circuit between the target device to which it is connected and the power supply; on the other hand, the operation and maintenance module can also serve as a reverse controller to reversely control the target device to which it is connected under the remote control of the management platform.

[0084] The target devices mentioned above refer to smart construction site equipment deployed on the construction site that need to access the network for data transmission or remote control, such as sensors (temperature, humidity, pressure sensors, etc.), cameras, fog cannons, enclosure spray equipment, distribution box electronic locks, etc.

[0085] Specifically, the operation and maintenance router is configured to collect the connection status of the target device to which it is connected and upload it to the management platform. The above connection status includes online status and offline status.

[0086] The operation and maintenance module is configured to collect the operating status of the target device to which it is connected and upload it to the management platform.

[0087] The management platform is configured to periodically restart the operation and maintenance modules one by one according to a preset inspection sequence, so that the target devices connected to the operation and maintenance modules are powered off during the shutdown period of the operation and maintenance modules, and obtain the target device connection status change data uploaded by the operation and maintenance router during the shutdown period of each operation and maintenance module; based on the target device connection status change data, determine the local circuit topology of the target device connected to the operation and maintenance module and the local network topology of the target device connected to the operation and maintenance router; construct a global circuit topology based on the local circuit topology, and construct a global network topology based on the local network topology; when it is monitored that the connection status of the target device is offline or the operating status of the target device is abnormal, locate the faulty device based on the global circuit topology and the global network topology, and execute the preset fault response strategy according to the fault location result.

[0088] Specifically, the above management platform is used for:

[0089] For each operation and maintenance module, when the operation and maintenance module is disconnected, the offline target device is added to the associated device set of the operation and maintenance module. If the associated device sets of two operation and maintenance modules intersect, the target devices in the intersection are removed from the associated device set of the operation and maintenance module that restarted first, according to the inspection order. After the inspection is completed, the local circuit topology of the target devices connected to each operation and maintenance module is constructed based on the associated device set of each operation and maintenance module.

[0090] For each operation and maintenance router, obtain the set of target devices connected to it; if the target device connected to the operation and maintenance router is offline only once during the inspection process, it is determined that the corresponding target device is directly connected to the operation and maintenance router; if the target device connected to the operation and maintenance router is offline more than once during the inspection process, it is determined that the corresponding target device is indirectly connected to the operation and maintenance router, and by finding the offline status of the relay device or bridge to which the operation and maintenance router is connected when the corresponding target device is offline, the connection relationship between the corresponding target device and the corresponding relay device or bridge is determined, and finally the local network topology of the target device connected to the operation and maintenance router is obtained.

[0091] Specifically, a whitelist may be set in the above-mentioned operation and maintenance router, and the operation and maintenance router may be further configured to perform network access control on access devices based on the whitelist, allowing only devices on the whitelist to access the network while excluding other devices from accessing the network.

[0092] Specifically, a backup power supply may be provided in the above-mentioned operation and maintenance module; the operation and maintenance module may also be configured to start the backup power supply to power itself and upload power failure information to the management platform when the power supply to which the operation and maintenance module is connected is powered off.

[0093] Specifically, the above management platform is also used for:
