Detailed ways

In order to make the purposes, 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 accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

Example 1

In order to solve the problem of poor remote scheduling management effect caused by the low reliability of data upload and delivery between the construction machinery equipment terminal and the cloud service platform, it is found through analysis that after the construction machinery equipment is connected to the cloud, due to the complex operating environment, Network volatility may cause the expected state of construction machinery and equipment to not be correctly delivered to the vehicle. On the other hand, the cloud server may collect the state data of construction machinery in an incorrect state, resulting in the sending of unaware error data to the data analysis module, which affects the final analysis result. The effect of construction machinery scheduling management will further lead to deviations or even failures of intelligent networked functions such as fault predictive analysis based on data mining.

After further research, it is found that general construction machinery uses cellular network technology for access, and good communication conditions are required to maintain smooth network communication with cloud servers. Interactions may fail, and retrying after failure will further consume network bandwidth and further deteriorate network conditions. To ensure smooth interaction of status data, the mode of QoS=1 or QoS=2 needs to be used for communication, which will further occupy network resources. If 5G communication technology is adopted, in order to solve the problem of network resources, it is possible to try to increase the density of base station deployment, but it will introduce cost problems.

Based on this, Embodiment 1 of the present invention provides a remote scheduling management method for remote scheduling and management of construction machinery equipment, which applies equipment shadowing. 1 is a schematic flowchart of a method for remote scheduling and management of construction machinery and equipment in Embodiment 1 of the present invention. As shown in FIG. 1 , the method for remote scheduling and management of construction machinery and equipment in Embodiment 1 of the present invention includes the following steps:

S101: Receive expected state information of construction machinery equipment delivered by a preset server.

Specifically, before receiving the expected state information of the construction machinery equipment sent by the server, the method further includes: creating a device shadow.

For example, the preset server is a cloud server (also referred to as a central server), which can write data to the desired part to update the expected state information.

S102: Receive current state information reported by the construction machinery equipment.

Specifically, the following three schemes may be adopted for receiving the current status information reported by the construction machinery equipment: the first scheme is: receiving the current status information reported by the construction machinery equipment according to the preset first cycle; the second scheme is: The first solution is: receiving the current state information reported when the construction machinery equipment accesses the device shadow; the third solution is: receiving the current state information reported by the construction machinery equipment according to the preset first cycle, and receiving Current status information reported by the construction machinery equipment when it accesses the equipment shadow. That is to say, the construction machinery equipment periodically sends messages to trigger status synchronization through the Reported field. When the network fluctuates and the vehicle is back online, it can also be set to send a status message immediately. If the Reported field is inconsistent with the expected status information stored in the shadow, it will automatically trigger status delivery and status check.

Further, before receiving the current state information reported by the construction machinery equipment, it also includes: sending authentication information to the server, the authentication information is related to the identity verification information of the construction machinery equipment, and a kind of construction machinery equipment in a cloud service. The platform has unique authentication information. The authentication information is returned to the cloud server when the device shadow is created. so that the construction machinery device can access the server through the authentication information. That is to say, the construction machinery and equipment are securely connected to the server through the authentication of the server's identity information. It should be noted that there is no certain order in which the expected status information is sent to the device shadow and whether the construction machinery equipment is connected to the cloud server. The construction machinery equipment can create access before the shadow device, or can create the access after the shadow device. After the construction machinery equipment is accessed through the authentication information, the pre-status information will be automatically synchronized to the construction machinery equipment.

For example, the construction machinery equipment can write the current status information to the reported part.

S103: Determine whether the current state information is the same as the expected state information.

Specifically, the expected state information carries first time information, and the current state information carries second time information, and the judging whether the current state information and the expected state information are the same may adopt the following scheme: whether the first time information and the second time information are the same. That is to say, the Desired field carries the etag field, which is used to indicate the data to be delivered at a certain point in time, and the Reported field also carries the etag field. When the value of the etag field in the Desired data in the shadow is the same as that in the Reported data in the report, it is not necessary to compare other business fields separately, and it is directly considered to be the same.

S104: When the current state information is different from the expected state information, deliver the expected state information to the construction machinery device.

The expected state information carries first verification information, and the current state information carries second verification information. As a further implementation manner, 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; when the first verification information is the same as the second verification information, send the current state information to the server, and the server analyzes and reports The current state information of the construction machinery is rewritten into the expected state information issued. When the first verification information is different from the second verification information, an alarm message is sent. For example, the status monitoring field AlertStatus of construction machinery equipment should be False. If the field in the reported data is True, it will be intercepted here, and the alarm and data analysis fields will be pushed. The data analysis fields and monitoring fields here Similarly, it refers to the abnormal state of a specific mechanical device, such as power, network strength, etc.

That is to say, Embodiment 1 of the present invention uses the concept of device shadow and message queue to realize the asynchronous state sending and data reporting communication mode. The construction machinery equipment monitoring system processing uplink and downlink data based on this mode can effectively solve the problems caused by construction machinery. The problem of poor remote scheduling management effect caused by the low reliability of data upload and delivery between the device and the cloud service platform. At the same time, the asynchronous communication feature based on the message queue can make the network anti-interference and not easily affected by the network fluctuation caused by the complex working environment of construction machinery.

As a further embodiment, the method for remote scheduling and management of construction machinery equipment in the equipment shadow further includes: receiving current status information reported by the construction machinery equipment, and sending the current status information to the server.

Specifically, the receiving the current state information reported by the construction machinery equipment may adopt the following scheme: receiving the current status information reported by the construction machinery equipment according to a preset second cycle.

In order to describe in more detail the method for remote dispatching and management of construction machinery and equipment according to Embodiment 1 of the present invention, a more detailed example is given. As shown in FIG. 2 , the method for remote dispatching and management of construction machinery and equipment includes the following steps:

1. Register construction machinery and equipment. At this time, the equipment shadow has been created. Send status data.

2. Access to construction machinery and equipment, and the construction machinery equipment and the shadow are synchronized.

3. Construction machinery equipment does not interact directly with the data analysis module. The data analysis module obtains the latest reported construction machinery equipment data by pulling shadow data.

It can be seen that the method for remote dispatching and management of construction machinery and equipment provided in Embodiment 1 of the present invention has the following beneficial effects:

(1) Through the introduction of device shadows, the functions of sending status and reporting data are changed to asynchronous implementation, reducing the dependence on the network in the overall process.

(2) When the network fluctuates, the state may be lost in the traditional way of synchronous command issuance, so that the cloud cannot grasp the execution of the command, and it is uncertain whether the status is successfully issued. The command issued by the device shadow method, the edge cloud saves the status that needs to be issued, and stores it in the form of "expected status/data", which is convenient for verification after the vehicle is reported. If the network fluctuates and the state sent from the shadow fails, when the data is reported periodically, the data can be automatically re-synchronized after the next report to ensure the final consistency of the state.

(3) If the reported data is inconsistent with the etag in desired and reported, it can be verified that the data reported at this time is not generated in the expected state and should not be used. In this way, the correctness of the data can be guaranteed, and the status can be corrected in time without manual re-issue.

(4) Compared with the synchronous mode, the efficient message interaction mode can improve the efficiency of the entire network and improve the throughput of effective messages.

The example application scenarios of the method for remote scheduling management of construction machinery equipment provided in Embodiment 1 of the present invention include the following.

1. Construction machinery and equipment operate in remote mines, and the communication conditions of mines are relatively poor. Edge servers are deployed in some specific locations around the mine, and construction machinery and equipment are connected to the edge server to accept the scheduling management of the edge server. Restricted by the operation scenario, the communication between construction machinery and edge servers is very unstable, construction machinery is frequently online and offline from the edge cloud server, and the reliability of data and information interaction cannot be guaranteed. The edge server sends the expected status information to the construction machinery equipment. The construction machinery equipment just dropped the line and cannot respond to the expected status information in time. After the construction machinery equipment reconnects to the edge server, it responds to this command, which has missed the best time. The response timing and scheduling management effect did not meet the expected planning of the edge server. Using the remote scheduling management method based on the device shadow mechanism, the edge server sends the expected state information of the nature of the control command, and the command carries the timestamp and is stored in the device shadow. When the device is disconnected and reconnected, obtain the command from the device shadow and determine whether to execute it according to the timestamp. Corresponding to the above-mentioned beneficial effects (1) (2) (3).

2. The construction machinery and equipment operate in the closed park of the city, the communication conditions of the closed park are better, and the construction machinery and equipment are directly connected to the central cloud server. The central cloud server can provide rich ecological function services such as predictive maintenance, driving navigation, path planning, air upgrade, monitoring and early warning. Many applications request to obtain the status information of construction machinery equipment, and construction machinery equipment needs to respond multiple times according to the requests of different applications, even if the response results are the same. The processing capacity of construction machinery and equipment itself is limited, and these state acquisition requests bring great pressure to its computing processing load. On the other hand, the central cloud server is connected to thousands of construction machinery devices, and these construction machinery devices report status information in response to different application requests, which also brings great challenges to the high concurrency capability of the central cloud server. Using the remote scheduling management method based on the device shadow mechanism, the construction machinery equipment only needs to actively synchronize the state to shadow the device once, and multiple applications request the device shadow to obtain the device status, and then the latest status of the construction machinery and equipment can be obtained, so that the application and equipment can be obtained. The decoupling (similar to the central cloud server side) greatly reduces the computational processing burden of construction machinery equipment and cloud servers. Corresponding to the above-mentioned beneficial effect (4).
