Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
In order to solve the problem that the remote scheduling management effect is poor due to low data uploading and issuing reliability between an engineering mechanical equipment end and a cloud service platform, analysis shows that after the engineering mechanical equipment is connected to a cloud end, due to the fact that the operation environment is complex, network fluctuation possibly causes that the expected state of the engineering mechanical equipment cannot be correctly issued to a vehicle. On the other hand, the cloud server may collect the engineering machine state data in an incorrect state, so that the undetected error data is sent to the data analysis module, the final analysis result is influenced, the scheduling management instruction based on the error analysis result influences the effect of the engineering machine scheduling management, and further deviation and even failure of intelligent networking functions such as fault predictive analysis based on data mining and the like are caused.
Further research shows that the general engineering machinery adopts a cellular network technology for access, needs good communication conditions for keeping smooth network communication with a cloud server, and when the network environment is poor and the network fluctuation is large, the state data interaction by adopting a synchronous interface in a traditional mode may fail, and the retry after the failure further occupies the network bandwidth to further deteriorate the network conditions. If the state data interaction is guaranteed to be smooth, the mode of QoS 1 or QoS 2 needs to be adopted for communication, and network resources are further occupied. If the 5G communication technology is adopted, in order to solve the problem of network resources, an attempt may be made to increase the deployment density of the base stations, but a cost problem is introduced.
Based on this, embodiment 1 of the present invention provides a remote scheduling management method for remote scheduling management of engineering mechanical equipment, which applies an equipment shadow. Fig. 1 is a schematic flow chart of a remote scheduling management method for engineering mechanical equipment in embodiment 1 of the present invention, and as shown in fig. 1, the remote scheduling management method for engineering mechanical equipment in embodiment 1 of the present invention includes the following steps:
s101: and receiving expected state information of the engineering mechanical equipment sent by a preset server.
Specifically, before receiving the expected state information of the engineering mechanical equipment sent by the server, the method further includes: a device shadow is created.
For example, the preset server is a cloud server (which may also be referred to as a central server) that can write data to the desired portion to update the expected state information.
S102: and receiving the current state information reported by the engineering mechanical equipment.
Specifically, the following three schemes may be adopted for receiving the current state information reported by the engineering mechanical equipment: the first scheme is as follows: receiving current state information reported by the engineering mechanical equipment according to a preset first period; the second scheme is as follows: receiving current state information reported when the engineering mechanical equipment is accessed to the equipment shadow; the third scheme is as follows: and receiving current state information reported by the engineering mechanical equipment according to a preset first period, and receiving the current state information reported when the engineering mechanical equipment is accessed to the equipment shadow. That is, the construction machinery device periodically sends messages to trigger state synchronization through the Reported field. When the network fluctuates and the vehicle comes online again, a status message can be set to be sent immediately, wherein the Reported field can automatically trigger status issuing and status checking if the Reported field is inconsistent with the expected status information stored in the shadow.
Further, before receiving the current state information reported by the engineering mechanical equipment, the method further includes: and sending authentication information to the server, wherein the authentication information is related to identity verification information of the engineering mechanical equipment, the engineering mechanical equipment has unique authentication information on a cloud service platform, and the authentication information is returned to the cloud server by the equipment shadow when the equipment shadow is created. And enabling the engineering mechanical equipment to be accessed to the server through the authentication information. That is, the construction machine equipment is securely connected to the server by the authentication of the identity information of the server. It should be noted that, there is no necessary order between issuing the expected status information to the device shadow and whether the engineering mechanical device accesses the cloud server. The access can be established by the engineering mechanical equipment before or after the shadow equipment. And the prior state information can be automatically synchronized to the engineering mechanical equipment after the engineering mechanical equipment is accessed through the authentication information.
For example, the work machine may write current state information to the ported portion.
S103: and judging whether the current state information is the same as the expected state information.
Specifically, the expected state information carries first time information, the current state information carries second time information, and the following scheme may be adopted to determine whether the current state information is the same as the expected state information: and judging whether the first time information is the same as the second time information. That is, the Desired field carries an etag field for indicating data to be delivered at a certain time point, and the Reported field also carries an etag field. When the value of the Desired data in the shadow is consistent with the value of the etag field in the Reported data, other service fields do not need to be compared separately, and the consistency is directly considered.
S104: and when the current state information is different from the expected state information, the expected state information is sent to the engineering mechanical equipment.
As a further implementation, before sending the current state information to the server, the method further includes: judging whether the first verification information is the same as the second verification information; and when the first verification information is the same as the second verification information, the current state information is sent to the server, and the server analyzes the reported current state information of the engineering machinery and rewrites the issued expected state information. And when the first verification information is different from the second verification information, sending an alarm message. For example, the monitoring field alert status of the operation state of the engineering machinery equipment should be False, if the field in the reported data is True, the field is intercepted here, and an alarm and data analysis field is pushed, where the data analysis field is similar to the monitoring field and indicates a specific abnormal machine state, such as electric quantity, network strength, and the like.
That is to say, in embodiment 1 of the present invention, an asynchronous state issue and data reporting communication mode is implemented by using an equipment shadow concept and a message queue, and an engineering mechanical equipment monitoring system that processes uplink and downlink data based on this mode can effectively solve the problem of poor remote scheduling management effect caused by low reliability of data upload and issue between an engineering mechanical equipment end and a cloud service platform. Meanwhile, based on the asynchronous communication characteristic realized by the message queue, the network has anti-interference performance and is not easily influenced by network fluctuation caused by the complex operation environment of the engineering machinery.
As a further embodiment, the method for remote scheduling and managing of the engineering mechanical equipment in the equipment shadow further includes: and receiving the current state information reported by the engineering mechanical equipment, and sending the current state information to the server.
Specifically, the following scheme may be adopted for receiving the current state information reported by the engineering mechanical equipment: and receiving current state information reported by the engineering mechanical equipment according to a preset second period.
To describe the remote scheduling management method for the engineering mechanical equipment in embodiment 1 of the present invention in more detail, a more detailed example is given, and as shown in fig. 2, the remote scheduling management method for the engineering mechanical equipment includes the following steps:
1. and registering the engineering mechanical equipment, wherein the equipment shadow is created. And issuing the state data.
2. And accessing the engineering mechanical equipment, and synchronizing the state of the engineering mechanical equipment and the shadow.
3. The engineering mechanical equipment does not directly interact with the data analysis module, and the data analysis module obtains the latest reported engineering mechanical equipment data by pulling the shadow data.
Therefore, the engineering mechanical equipment remote scheduling management method provided by the embodiment 1 of the invention has the following beneficial effects:
(1) by introducing the shadow of the equipment, the functions of state sending and data reporting are changed into asynchronous realization, and the dependence on the network in the whole process is reduced.
(2) When the network fluctuates, the state may be lost in a conventional synchronous command issuing manner, so that the cloud cannot grasp the execution condition of the command, and is uncertain whether the state is successfully issued. The peripheral cloud stores the state to be issued by adopting the command issued by the device shadow mode, and stores the state in an expected state/data mode, so that the vehicle can conveniently check after reporting. If the network fluctuates, the state delivered from the shadow fails, and when the data is periodically reported, the data can be automatically delivered synchronously again after the next report, so that the final consistency of the state can be ensured.
(3) If the etag in the reported data is not consistent with the etag in the desired data, it can be verified that the reported data is not generated in the expected state and should not be used. Therefore, the correctness of the data can be guaranteed, the state can be corrected in time, and manual resending is not needed.
(4) Compared with a synchronous mode for sending the state, the efficient message interaction mode can improve the efficiency of the whole network and improve the throughput of effective messages.
Application scenarios of the engineering mechanical equipment remote scheduling management method provided by embodiment 1 of the present invention include the following.
1. The engineering mechanical equipment runs in remote mines, and the communication conditions of the mines are poor. Edge servers are deployed at specific places around the mine, and the engineering mechanical equipment is in communication connection with the edge servers and receives scheduling management of the edge servers. Limited by an operation scene, communication between the engineering mechanical equipment and the edge server is unstable, the engineering mechanical equipment is frequently on-line and off-line from the edge cloud server, and the reliability of data information interaction cannot be guaranteed. The edge server sends expected state information to the engineering mechanical equipment, the engineering mechanical equipment is just disconnected and cannot respond to the expected state information in time, after the engineering mechanical equipment is connected to the edge server again, the instruction is responded, the best response opportunity is missed, and the scheduling management effect does not reach the expected planning of the edge server. The remote scheduling management method based on the device shadow mechanism is used, the edge server sends expected state information of the property of a control instruction, and the instruction is stored in the device shadow with a timestamp. When the device is disconnected and reconnected, the instruction is obtained from the shadow of the device and whether the execution is carried out is determined according to the time stamp. Advantageous effects (1), (2) and (3) described above are achieved.
2. The engineering mechanical equipment runs in a closed park of a city, the communication condition of the closed park is good, and the engineering mechanical equipment is directly connected with the central cloud server. The central cloud server can provide rich ecological function services such as predictive maintenance, driving navigation, path planning, air upgrading, monitoring and early warning and the like. Many applications request to acquire status information of the construction machine, and the construction machine needs to respond many times according to the requests of different applications, even if the response results are the same. The processing capacity of the engineering machinery equipment is limited, and the state acquisition requests bring great pressure to the calculation processing load of the engineering machinery equipment. On the other hand, the central cloud server is connected with thousands of engineering mechanical devices, and the engineering mechanical devices respond to different application program requests to report state information, which also brings great challenges to the high concurrency capability of the central cloud server. By using the remote scheduling management method based on the equipment shadow mechanism, the engineering mechanical equipment only needs to actively synchronize the state to the equipment shadow once, and the latest state of the engineering mechanical equipment can be obtained by a plurality of application programs requesting the equipment shadow to obtain the equipment state, so that the decoupling of the application programs and the equipment (the same-processing center cloud server end) is realized, and the calculation processing burden of the engineering mechanical equipment and the cloud server is greatly reduced. Advantageous effects (4) described above are achieved.
