Obviously, the accompanying drawings in the following description are some embodiments of this specification.

Detailed implementation manners

[0019] First of all, it should be noted that the terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The singular forms of "a", "the", and "said" used in the embodiments of the present invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0020] In order to enable those skilled in the art to better understand the technical solutions in this specification, the following will clearly and completely describe the technical solutions in the embodiments of this specification in conjunction with the accompanying drawings in the embodiments of this specification. Obviously, the described embodiments are only a part of the embodiments of this specification, rather than all the embodiments. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described here without departing from the scope and spirit of the present invention. Similarly, for the sake of clarity and conciseness, the descriptions of well-known functions and structures are omitted below.

[0021] It should be noted that: in other embodiments, the steps of the corresponding methods are not necessarily executed in the order shown and described in this specification. In some other embodiments, the steps included in the method may be more or less than those described in this specification. In addition, a single step described in this specification may be decomposed into multiple steps for description in other embodiments; and multiple steps described in this specification may also be combined into a single step for description in other embodiments.

[0022] The following will further elaborate on a method and system for intelligent construction site equipment operation and maintenance management described in the embodiments of this specification in conjunction with the accompanying drawings of the specification and specific embodiments, but this detailed description does not constitute a limitation to the embodiments of this specification.

[0023] Please refer to Figure 1 , Figure 1 which shows a schematic flow diagram of a method for the operation and maintenance management of intelligent construction site equipment. This method is applicable to an intelligent 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. Among them, the operation and maintenance router is powered by a power supply (in a construction site, the power supply usually refers to a distribution box), and provides network access functions for one or more target devices connected thereto. At the same time, the operation and maintenance router can collect the connection status of the target devices connected thereto in real time and upload it to the management platform. The connection status includes an online status and an offline status. The operation and maintenance module is connected to the power supply and is also connected to one or more target devices. On the one hand, the operation and maintenance module can be used as a data collection module to collect operation status data of the target devices connected thereto and upload it to the management platform through a built-in network module; on the other hand, the operation and maintenance module can be used as a power switch to control the on / off of the power supply circuit between the target devices connected thereto and the power supply; on the other hand, the operation and maintenance module can also be used as a reverse controller to perform reverse control on the target devices connected thereto under the remote control of the management platform.

[0024] The above-mentioned target devices refer to intelligent construction site devices deployed in a construction site that need to access the network for data transmission or remote control, such as sensors (temperature, humidity, pressure sensors, etc.), cameras, fog cannon machines, enclosure spraying devices, distribution box electronic locks, and so on.

[0025] As Figure 1 shown, the above-mentioned method for the operation and maintenance management of intelligent construction site equipment includes steps S100 to S110.

[0026] S100: Collect the connection status of the target devices connected thereto through the operation and maintenance router and upload it to the management platform.

[0027] Since the target devices need to register the physical address when accessing the network, the operation and maintenance router can uniquely identify the accessed target devices through the physical address and collect the connection status of the target devices connected thereto and upload it to the management platform. The connection status of the above-mentioned target devices includes an online status and an offline status.

[0028] It should be noted that the number of operation and maintenance routers can be determined according to requirements, 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.

[0029] In some embodiments, a whitelist can be set in the operation and maintenance router to control the access of legal devices. The operation and maintenance router performs network access control on the accessed devices based on the whitelist, only allowing the devices on the whitelist to access the network and excluding other devices from accessing the network. Through this setting, the devices accessed by the operation and maintenance router can be controlled to prevent other illegal devices on the construction site from accessing and occupying network resources, thereby affecting the data transmission rate of the smart construction site devices.

[0030] S102: Collect the operating status of the target device connected thereto by the operation and maintenance module and upload it to the management platform.

[0031] The operation and maintenance module can collect the operating status data of the target device connected thereto through the bus. The bus protocol adopted by the operation and maintenance module can be set according to requirements, and this embodiment does not limit this. For example, the operation and maintenance module can communicate with the target device connected thereto through the RS485 bus protocol to collect the operating status data of the target device connected thereto.

[0032] In addition, the operation and maintenance module can also monitor the status data of the power supply connected thereto. In some embodiments, a backup power supply can be set in the operation and maintenance module. When the power supply connected to the operation and maintenance module is powered off, the operation and maintenance module starts the backup power supply to supply power to itself and uploads power failure information to the management platform.

[0033] It should be noted that the backup power supply and its working mode can be implemented by any existing technology that can achieve the same technical effect. This embodiment does not limit this and will not elaborate further.

[0034] S104: Regularly restart each operation and maintenance module one by one through the management platform according to the preset inspection order, so that the target devices connected to the operation and maintenance module are powered off during the shutdown of the operation and maintenance module, and obtain the data on the change of the connection status of the target devices uploaded by the operation and maintenance router during the shutdown period of each operation and maintenance module.

[0035] The construction site scenario is different from the conventional business scenario. As the construction progress of the construction site advances, the positions and connection relationships of the smart construction site devices often change, which makes it difficult to quickly and accurately locate faults when a fault occurs.

[0036] 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.

[0037] Specifically, for each construction site, the management platform can number the operation and maintenance modules deployed at the construction site and set the inspection order according to the number order (for example, perform inspections in ascending order of the numbers), and then restart each operation and maintenance module at 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, then turning off and then turning on the second operation and maintenance module, ensuring that only one operation and maintenance module is turned off each time, and so on until the restart step is executed for all operation and maintenance modules at the construction site. When the operation and maintenance module is turned off, it will cut off the power supply circuit of the target device it is connected to, causing the target device it is connected to to lose power.

[0038] In some embodiments, a relay can be set in the above-mentioned operation and maintenance module. After the management platform sends a restart command to the operation and maintenance module, the operation and maintenance module controls the relay to disconnect and then reconnect the operation and maintenance module from the power supply according to the restart command.

[0039] Obviously, when a certain operation and maintenance module is disconnected, the various target devices it is connected to will go offline due to power loss. Going offline means that the target device changes from an online state to an offline state. At this time, the target device connection status data uploaded by the corresponding operation and maintenance router will change, and this target device connection status change data is the information of the target devices that went offline during the disconnection of the operation and maintenance module.

[0040] 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 cycle of the management platform implementing the inspection process and the time node when the inspection starts can be set according to requirements, and this embodiment does not limit this.

[0041] S106: Based on the target device connection status change data, determine the local circuit topology of the target devices connected to the operation and maintenance module and the local network topology of the target devices connected to the operation and maintenance router.

[0042] The operation and maintenance router can only obtain which 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.

[0043] 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 devices connected to the operation and maintenance module and the local network topology of the target devices connected to the operation and maintenance router.

[0044] First, introduce the construction method of the local circuit topology of the target devices connected to the operation and maintenance module. For each operation and maintenance module, when the module is disconnected, the target devices that go offline are included in the associated device set of the operation and maintenance module. If there is an intersection between the associated device sets of two operation and maintenance modules, then according to the inspection order, the devices in the intersection are removed from the associated device set of the operation and maintenance module that was restarted earlier. After the inspection is completed, based on the associated device set of each operation and maintenance module, the local circuit topology of the target devices connected to the operation and maintenance module is constructed.

[0045] Please refer to Figure 3 , Figure 3 which shows the topology relationship diagram of the target devices in an implementation scenario. As Figure 3 shown, operation and maintenance module 1 is connected to camera 1, camera 2, and the network bridge, that is, operation and maintenance module 1 supplies power to camera 1, camera 2, and the network bridge. Operation and maintenance module 2 is connected to camera 3, that is, 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 through the network bridge, that is, there is an indirect network connection between camera 3 and the operation and maintenance router. It should be noted that for simplicity of the drawing, the power supply is not shown in Figure 3 .

[0046] Taking the Figure 3 shown topology as an example to elaborate on the construction process of the local circuit topology of the target devices connected to the operation and maintenance module. According to the inspection order, the management platform first controls operation and maintenance module 1 to restart, that is, controls operation and maintenance module 1 to disconnect and then reconnect. When operation and maintenance module 1 is disconnected, the operation and maintenance router will detect that camera 1, camera 2, camera 3, and the network bridge go offline. At this time, camera 1, camera 2, camera 3, and the network bridge are included in the associated device set of operation and maintenance module 1. Next, the management platform controls operation and maintenance module 2 to restart, that is, controls operation and maintenance module 2 to disconnect and then reconnect. When operation and maintenance module 2 is disconnected, the operation and maintenance router will detect that camera 3 goes offline. At this time, camera 3 is included in the associated device set of operation and maintenance module 2. Obviously, at this time, there is an intersection between the associated device set of operation and maintenance module 1 and the associated device set of operation and maintenance module 2, that is, camera 3. According to the inspection order, operation and maintenance module 1 is restarted first, so camera 3 is removed from the associated device set of operation and maintenance module 1. Finally, the associated device set of operation and maintenance module 1 is {camera 1, camera 2, network bridge}, and the associated device set of operation and maintenance module 2 is {camera 3}. Since the target devices in the associated device set of the operation and maintenance module are directly circuit-connected to the operation and maintenance module, the local circuit topology of the target devices connected to each operation and maintenance module can be determined.

[0047] 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, obtain the set of target devices it is connected to. If the target device connected to the operation and maintenance router only experiences a disconnection 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 experiences more than one disconnection during the inspection process, it is determined that the corresponding target device is indirectly connected to the operation and maintenance router. By checking the disconnection status of the relay device or bridge connected to the operation and maintenance router 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 devices connected to the operation and maintenance router is obtained.

[0048] Continuing with Figure 3 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 only experience a disconnection once, so it can be determined that Camera 1, Camera 2, and the Bridge are directly connected to the operation and maintenance router. Here, the direct connection refers to a direct network connection. However, Camera 3 experiences two disconnections during the inspection process, so it can be determined that Camera 3 is indirectly connected to the operation and maintenance router, that is, Camera 3 is connected to the operation and maintenance router through a bridge or a relay device. At this time, check the disconnection status of other devices when Camera 3 is disconnected and find that the Bridge and Camera 3 are disconnected simultaneously (when Camera 3 is disconnected for the first time, the Bridge is also disconnected). 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.

[0049] S108: Construct the global circuit topology based on the local circuit topology and construct the global network topology based on the local network topology.

[0050] After step S106, the local network topology of the target devices connected to each operation and maintenance router and the local circuit topology of the target devices connected to each operation and maintenance module can be obtained.

[0051] Piece together the local circuit topologies of the target devices connected to the operation and maintenance modules to obtain the corresponding global circuit topology.

[0052] Piece together the local network topologies of the target devices connected to the operation and maintenance routers to obtain the corresponding global network topology.

[0053] S110: When the management platform monitors that the connection status of the target device is the offline state or the operation status of the target device is the abnormal state, locate the faulty device based on the global circuit topology and the global network topology.

[0054] The management platform can monitor the connection status of the target devices and the running status of the target devices. When it is found that one or more target devices are offline or the running status is abnormal, the faulty devices are located based on the global circuit topology and the global network topology.

[0055] It should be noted that the above method for judging whether the running status of the target device is abnormal can be set according to requirements. For example, the rule matching or threshold matching method can be used to determine whether the running status of the target device is abnormal. This embodiment does not limit this.

[0056] S112: The management platform executes a preset fault response strategy according to the fault location result.

[0057] Generally, common faults can usually be solved by restarting the device. Therefore, in this step, after determining the location of the faulty device, the management platform can search the global circuit topology according to the fault location result, and restart the faulty branch circuit through the corresponding operation and maintenance module. If the faulty device resumes operation after restarting the faulty branch circuit, the fault response strategy execution ends, and a fault log is recorded and pushed to the operation and maintenance personnel; otherwise, the fault location result is sent to the operation and maintenance personnel to notify the operation and maintenance personnel to go to the site for maintenance.

[0058] In some cases, some target devices can resume operation after restarting, and in this case, it is not necessary for the operation and maintenance personnel to go to the site for maintenance. It is only necessary to remotely restart these target devices through the management platform.

[0059] For the target devices that still cannot resume operation after restarting, it is necessary to notify the operation and maintenance personnel to go to the site for maintenance. At this time, the location result of the faulty device needs to be sent to the operation and maintenance personnel to help the operation and maintenance personnel quickly find the faulty device when they arrive at the site, saving the time cost of manual troubleshooting.

[0060] Corresponding to the above method for operation and maintenance management of target devices, this embodiment also provides a smart construction site equipment operation and maintenance management system, which is used to implement the above method for operation and maintenance management of smart construction site equipment. Please refer to Figure 2, the system includes: a management platform, an operation and maintenance router, an operation and maintenance module, and target devices. Among them, 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 functions for one or more target devices connected thereto. At the same time, the operation and maintenance router can collect the connection status of the target devices connected thereto in real time and upload it to the management platform, and the connection status includes an online status and an offline status. The operation and maintenance module is connected to the power supply and is also connected to one or more target devices. On the one hand, the operation and maintenance module can be used as a data collection module to collect the operation status data of the target devices connected thereto and upload it to the management platform through the built-in network module; on the other hand, the operation and maintenance module can be used as a power switch to control the on-off of the power supply circuit between the target devices connected thereto and the power supply; on the other hand, the operation and maintenance module can also be used as a reverse controller to perform reverse control on the target devices connected thereto under the remote control of the management platform.

[0061] The above-mentioned target devices refer to smart construction site devices deployed on a construction site that need to access the network for data transmission or remote control, such as sensors (temperature, humidity, pressure sensors, etc.), cameras, fog cannon machines, enclosure spraying devices, distribution box electronic locks, and so on.

[0062] Specifically, the operation and maintenance router is configured to collect the connection status of the target devices connected thereto and upload it to the management platform, and the above-mentioned connection status includes an online status and an offline status.

[0063] The operation and maintenance module is configured to collect the operation status of the target devices connected thereto and upload it to the management platform.

[0064] The management platform is configured to regularly restart each operation and maintenance module in accordance with a preset inspection order, so that the target devices connected to the operation and maintenance module are powered off during the period when the operation and maintenance module is turned off, and obtain the target device connection status change data uploaded by the operation and maintenance router during the period when each operation and maintenance module is turned off; based on the target device connection status change data, determine the local circuit topology of the target devices connected to the operation and maintenance module and the local network topology of the target devices 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 detected that the connection status of the target device is in an offline state or the operation status of the target device is in an abnormal state, locate the faulty device based on the global circuit topology and the global network topology, and execute a preset fault response strategy according to the fault location result.

[0065] Specifically, the above-mentioned management platform is specifically used for: For each operation and maintenance module, when the operation and maintenance module is disconnected, the target devices that go offline are classified into the associated device set of the operation and maintenance module; if there is an intersection between the associated device sets of two operation and maintenance modules, then according to the inspection order, the target devices in the intersection are removed from the associated device set of the operation and maintenance module that was restarted earlier; after the inspection is completed, based on the associated device set of each operation and maintenance module, a local circuit topology of the target devices connected by the operation and maintenance module is constructed. For each operation and maintenance router, obtain the set of target devices it connects; if the target devices connected by the operation and maintenance router go offline only once during the inspection process, it is determined that the corresponding target devices are directly connected to the operation and maintenance router; if the target devices connected by the operation and maintenance router go offline more than once during the inspection process, it is determined that the corresponding target devices are indirectly connected to the operation and maintenance router, and by checking the offline situation of the relay devices or bridges connected by the operation and maintenance router when the corresponding target devices go offline, the connection relationship between the corresponding target devices and the corresponding relay devices or bridges is determined, and finally the local network topology of the target devices connected by the operation and maintenance router is obtained.

[0066] Specifically, a whitelist can be set in the above-mentioned operation and maintenance router, and the operation and maintenance router can also be configured to perform network access control on the access devices based on the whitelist, only allowing the devices on the whitelist to access the network and excluding other devices from accessing the network.

[0067] Specifically, a backup power supply can be set in the above-mentioned operation and maintenance module; the operation and maintenance module can also be configured to, when the power supply connected by the operation and maintenance module is powered off, start the backup power supply to supply power to itself and upload power failure information to the management platform.
