The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention.
The embodiment of the application provides an architecture for managing and controlling parking lot devices, which includes a cloud server 10, a plurality of parking lot servers 20, and a plurality of managed and controlled target devices 30, where a device management application is set in the parking lot servers 20.
The parking lot lan 40 is composed of a plurality of target devices 30 and a parking lot server 20, and the parking lot server 20 is a server. The parking lot server 20 is connected to the cloud server, and the target device 30 is connected to the cloud server through the parking lot server 20. The parking lot servers 20 of a plurality of parking lots are connected to the cloud server 10. The target device 30 may report information to the cloud server through the parking lot server 20, and the cloud server may issue a management and control instruction or transmit other data through the parking lot server 20. The parking lot server 20 may be a separate computing device dedicated to lan services, such as a server of a separate device, a personal computer, etc.; or a specific device with a local area network service function in the parking lot device. The target devices 30 include various devices commonly used in parking lots, such as an industrial personal computer, a low-level video pile, a high-level near-gun camera, a monitoring camera, a sensor, and the like.
The construction of the architecture includes a preparation phase and a deployment phase.
A preparation stage: the database of the cloud server 10 enters information of virtual gateway devices that the device management application needs to actually manage and information of target devices 30 managed by the virtual gateway. Such information includes, but is not limited to, device unique code, product unique code, device initial state, device hardware version number, device software version number, last communication time of the device.
A deployment phase: if there are a plurality of parking lots to be accessed to the architecture, each parking lot is assigned at least one server as a parking lot server 20, and at least one device management application is deployed in each parking lot server 20. Each device management application manages the target devices 30 in the parking lot and forms a local area network with a plurality of target devices 30. At this time, at least one server is allocated in the internet server to serve as the cloud server 10, so as to deploy the device management of the cloud server 10.
What this application will realize is, through parking area server 20 and high in the clouds server-side intercommunication, get through the information gap between a plurality of parking area LAN 40, realize the unified management, remote management and the operation of crossing the scene of a plurality of parking areas. Meanwhile, the parking server 20 performs self-management and self-maintenance of the devices in the parking lot.
Next, a detailed description will be given of a management and control method of a parking lot device according to an embodiment of the present application, which includes steps S100 to S500, from the perspective of the parking lot server 20.
S100: after the device management application is started, the device management application is connected to the cloud server 10.
Specifically, the device management application is connected to the cloud server 10 through TCP.
After receiving the gateway information, the cloud server 10 queries the cloud database, finds an information list of the target device 30 managed under the gateway information, and returns the information list to the device management application in a json manner. The device management application issues the device data in the information list layer by layer according to different target devices 30, and finally sends the device data to each target device 30 through virtual driving and actual driving of each product.
S200: when the device management application is successfully connected to the cloud server 10, device data is acquired from the target device 30 and the cloud server 10.
Specifically, after the connection is successful, the gateway information is reported to the cloud server 10 through the device management application. And receives the list of information of the target device 30 returned by the cloud server 10.
S300: when the device data is successfully acquired, the target device 30 and the cloud server 10 are connected through the device management application according to the judgment on the device data.
S400: listening whether the device management application or the target device 30 has occurred with the first trigger event.
Specifically, the first trigger event may include whether the device management application is disconnected from the cloud server, whether the device management application is reconnected with the cloud server, whether the target device 30 has a fault, whether a system of the target device 30 needs to be upgraded, and the like.
S500: and if the first trigger event occurs, executing the first business operation.
Specifically, the first business operation includes sending a connection request to the cloud service, restarting the parking lot server 20, sending failure notification information to the cloud server 10, downloading upgrade data for the target device 30 and upgrading the system, and the like.
In one embodiment, step S200 specifically includes: the first device data is acquired from the target device 30, and the second device data is acquired from the cloud server 10. Specifically, the device data includes first device data and second device data, and the first device data is uploaded to the device management application by the target device 30. The second device data is provided by the device management application from the information list returned by the cloud server 10 according to the difference of the target device 30.
In one embodiment, step S300 specifically includes: after the device data is successfully acquired, whether the first device data is matched with the second device data is judged, if yes, the target device 30 and the cloud server 10 are connected through the device management application, and a device shadow is initialized according to the second device data; if not, the target device 30 cannot be online to connect with the cloud server 10, and the target device 30 is not activated. Specifically, the first device data and the second device data are successfully matched, the device data can actually reach the target device 30, the target device 30 and the configuration are proved to be correct, the device data is directly stored in a storage space of the device management application, the device data is a device shadow, that is, the device shadow is successfully initialized, and meanwhile, the device management application sends a notification that the target device 30 is successfully online to the cloud server 10.
In one embodiment, step S500 may include S501-S502.
S501: if the connection state between the device management application and the cloud server 10 is disconnected, the device management application continuously sends a connection request to the cloud server 10, and writes the real-time device data of the target device 30 into the device shadow.
S502: if the device management application is successfully reconnected with the cloud server 10 by sending the connection request, comparing the device data before disconnection with the device data after reconnection, screening out the device data which changes after reconnection, and sending the device data to the cloud server 10.
As a specific example, when a network fluctuation occurs, the device management application may disconnect from the cloud server 10, and the cloud server 10 may lose the management of the target device 30. At this time, although both the devices are disconnected, the device management application continuously attempts to connect to the cloud server 10, no failure occurs between the device management application and the cloud server 10, the target device 30 managed by the device management application still operates, and the device shadow stored in the device management application updates all the device data of the target device 30 in real time during the disconnection period. Even if the connection with the cloud server 10 is interrupted, the device management application can continue to manage the target device 30 in the parking lot through the local area network and the device shadow, so that the robustness and stability of the parking lot device management system are improved, and the resistance to network instability risks is enhanced.
After the device management application succeeds in reconnecting the cloud server 10, the change of the device data before and after disconnection is compared at the first time, and if all states of the target device 30 do not change in the period, both application parties (the device management application and the cloud server 10) do not need to perform data communication, otherwise, information is synchronized between the two application parties. Without the device shadow, the information needs to be synchronized each time the application is disconnected due to network fluctuation and other accidents, which causes very large network pressure. On the contrary, the embodiment only needs to report the device data with information change, which greatly reduces the network overhead.
As an improvement, if the device management application cannot be successfully connected for a long time or after sending connection requests for multiple times after disconnecting from the cloud server 10, steps S503 to S504 may be adopted.
S503: and judging whether the number of times or time for sending the connection request exceeds a threshold value, if so, restarting the parking lot server 20, and then sending the connection request to the cloud server 10 again through the equipment management application.
Specifically, the parking lot management system can solve most of network disconnection conditions caused by system problems by restarting the parking lot server 20, so that even if network disconnection occurs due to system reasons in some software aspects, the parking lot management system can realize automatic management and self-maintenance, operation and maintenance personnel or management personnel do not need to be informed about things, and a large amount of labor cost and time cost are saved.
S504: and judging whether the number of times or time for sending the connection request again exceeds a threshold value, if so, starting the backup device management application to connect the cloud server 10, and sending failure reporting information to the cloud server 10 through the backup device management application.
Specifically, if the parking lot server 20 is restarted, the network outage problem cannot be solved, which indicates that the problem is beyond the capability range of self-management and self-maintenance of the parking lot management system, at this time, the device management application can be backed up in advance, and the device management application is connected with the cloud server 10 through another communication line and sends failure reporting information to notify operation and maintenance personnel or managers to handle the network outage problem in time.
In one embodiment, if the system update status of the target device 30 is to be upgraded, the target device 30 loads upgrade data from the device shadow to complete system upgrade of the target device 30.
Specifically, the database of the cloud server 10 stores real-time device data of the target device 30, including a software version number of the target device 30. The device data is generally entered in a preparation stage, and when the cloud server 10 is connected to the target device 30, the target device 30 uploads real-time device data, and the device data of the target device 30 is synchronized in real time. After the operation and maintenance personnel issue the upgrade instruction to the target device 30 through the cloud server 10, the cloud server 10 compares the upgrade version number with the software version number of the current target device 30, and screens out the upgradable target device 30. Meanwhile, the cloud server 10 finds the target device 30 managed under the corresponding device management application through TCP connection, and sends the upgrade software package to the corresponding device management application. After the device management application receives the upgrade software package, the device shadow performs cooperative work with the corresponding target device 30SDK according to the device state of the current target device 30, decompresses the upgrade software package, and then performs system upgrade on the target device 30. The system upgrading mode can remotely control a plurality of parking lot servers 20, the remote upgrading purpose is achieved, manual intervention on each target device 30 is not needed, and operation and maintenance cost required by upgrading is saved.
In one embodiment, if the operation status of the target device 30 is a failure, an error message is sent to the cloud server 10 through the device management application.
Specifically, when a target device 30 in a parking lot lan 40 is abnormal (i.e., has a fault), device information of the abnormal target device 30 is reported layer by layer, from an actual driving device to a virtual gateway, and finally reported to the cloud server 10 through a device management application, and the cloud server 10 processes device data in time after receiving an alarm message. The concept of centralized management is not common, the management systems of most of the existing parking lots are limited in local area networks of the parking lots, so that self-management of only one parking lot in a small range can be realized, a large amount of manpower is needed for squatting and patrolling in each parking lot, and time and labor are wasted. On the contrary, the cloud server 10 deployed in the public network manages multiple target devices 30 in multiple local area networks at the same time, and can administer the target devices 30 in multiple different parking lots at the same time, thereby greatly reducing the research and development cost and the management, operation and maintenance cost.
The embodiment of the present application provides a management and control device for parking lot equipment, which includes an external connection unit 100, a data integration unit 200, an internal connection unit 300, an event monitoring unit 400, and an event execution unit 500.
The external connection unit 100 is used for connecting the device management application and the cloud server 10 after the device management application is started. Specifically, the external connection unit 100 is used for the parking lot lan 40 to perform communication connection with the cloud server 10 outside the parking lot.
When the device management application is successfully connected to the cloud server 10, the data integration unit 200 acquires device data from the target device 30 and the cloud server 10, and initializes the device shadow of the target device 30 according to the device data.
When the device data is successfully acquired, the internal connection unit 300 connects the target device 30 and the cloud server 10 through the device management application according to the judgment of the device data. Specifically, the internal connection unit 300 is used for connecting the device management application in the parking lot to the target device 30, the connection of the target device 30 to the device management application forms a local area network in the parking lot, and the target device 30 is also connected and communicated with the cloud server 10 through the device management application.
