Description

Technical Field

[0001] The present invention relates to the field of Hongmeng smart device communication technology, and specifically to a Hongmeng smart multi-person electronic signage system. Background Art

[0002] At present, the mine equipment power outage needs to be handled by the power outage application unit. The work ticket mainly includes the power outage application unit, power outage location, power outage time, power outage reason, power outage impact range, and power outage person in charge. It must be approved and signed by ventilation, electromechanical, antong, dispatch, and chief engineer. It is difficult to form a closed loop of maintenance work with all paper management;

[0003] Maintenance operations are generally conducted through oral conversations, telephone contacts, and paper signs. Once a person makes a mistake in operation, it is easy to cause an accident. Sometimes the maintenance time is too long, there is no handover during shift changes, and other personnel mistakenly send power, causing equipment damage and casualties, which poses a great safety hazard. Summary of the invention

[0004] The purpose of the present invention is to propose a Hongmeng intelligent multi-person electronic signage system in response to the problems existing in the background technology.

[0005] The technical solution of the present invention: a Hongmeng intelligent multi-person electronic signage system, comprising:

[0006] Mobile management and control app, used for connection management, initiation of operation requests, receipt of approval information and device status control with Hongmeng smart devices based on the OpenHarmony system in the Hongmeng smart multi-person electronic signage system;

[0007] Hongmeng smart devices based on the OpenHarmony system are used to undertake the tasks of data transmission, operation records, forwarding of approval applications and executing maintenance instructions.

[0008] Preferably, the workflow of the Hongmeng intelligent multi-person electronic signage system is as follows:

[0009] S21. When the Hongmeng smart device application based on the OpenHarmony system is enabled, the Socket service will be started according to the network environment of the Hongmeng smart device. When any maintenance operator holds the control device close to the NFC tag attached to the Hongmeng smart device, the mobile control App reads the Bluetooth connection information of the Hongmeng smart device in the NFC and automatically connects after reading the Bluetooth connection information.

[0010] S22. After the mobile phone management and control App successfully connects to the Hongmeng smart device, the sign-on operation is performed in the operation interface. The sign-on operation is successfully recorded in the current sign-on record table, and is prominently displayed in the visual interface of the Hongmeng smart device to prompt other sign-on operators, and a sign-on record is added to the Hongmeng smart device database;

[0011] Among them, other listing operators are audit operators;

[0012] S23. After the maintenance operator is successfully posted, the Hongmeng smart device sends the socket connection method, i.e., the IP and port number, to the mobile app, and the mobile management and control app establishes a connection with the Hongmeng smart device.

[0013] S24. After the mobile control App is connected to the Hongmeng smart device through a socket, the maintenance operator can submit a temporary unblocking application information I through the mobile control App if he wants to verify the maintenance effect after completing the maintenance operation;

[0014] S25. After receiving the temporary unblocking application, the Hongmeng smart device forwards the application to the mobile control App of the audit operator through socket message sending. After receiving the application, the mobile control App of the audit operator emits obvious vibration and alarm sound to remind the operator, and converts the temporary unblocking application information I into temporary unblocking application information II, and displays the temporary unblocking application information II.

[0015] S26. The review operator determines whether to approve the temporary release application based on his own maintenance situation:

[0016] If any one of the review operators disagrees, the application will be put on hold and remain in a waiting state;

[0017] If all the review operators agree to the temporary unblocking application at this time, the mobile management app of the operator who submitted the temporary unblocking application information I obtains the temporary unblocking permission. At this time, the Hongmeng smart device enters the temporary unblocking state and operates normally. The temporary unblocking starts counting down according to the unblocking time applied, and S27 is executed;

[0018] S27. The operator of the temporary unblocking application information I, i.e. the maintenance operator, obtains the operating status data of the Hongmeng smart device through the mobile phone control App. The maintenance operator sends instructions to the Hongmeng smart device by operating the mobile phone control App to check whether the operating status of the Hongmeng smart device is normal. After the countdown ends, the temporary unblocking state ends and the maintenance operator loses the operation authority. If he wants to operate again, he needs to resubmit the application;

[0019] S28. If the maintenance operator verifies that the maintenance operation is normal through temporary unhooking, the maintenance operator connects to the Hongmeng smart device via Bluetooth, and then unhooks through the normal unhooking mode of the mobile phone management App. After unhooking, the Hongmeng smart device deletes the listing information of the user. When the listing information of all devices is deleted, the device changes from the listing state to the normal working state.

[0020] Preferably, the Hongmeng intelligent multi-person electronic signage system manages the maintenance processes with mutual interlocking control, and the mobile phone management and control App of the signage enables all maintenance personnel to communicate and debug with each other through near-field and far-field control. All maintenance processes are interlocked and controlled with each other, and the far-field control of the mobile phone management and control App allows all maintenance personnel to communicate and debug with each other.

[0021] Preferably, the Hongmeng smart device based on the OpenHarmony system is equipped with a Hongmeng smart device-side application, which is developed using OpenHarmonyArkTs. When the application is started, two services will be started, including: Service I and Service II;

[0022] Service I is used to process BLE Bluetooth data services, and its processed data objects will be encapsulated as Bluetooth data transmission objects;

[0023] Service II is used to process the services of socket data objects. The data transmitted through the socket will be encapsulated into a Socket data transmission object and data transmission processing will be performed.

[0024] Preferably, a message queue mode is adopted in the process of data transmission processing, and the weight of the modification instruction message is greater than that of the query instruction.

[0025] Preferably, the unblocking application information I includes the unblocking reason and the temporary unblocking operation time.

[0026] Preferably, the temporary release application information II includes the applicant, the reason for the application and the temporary release time.

[0027] Preferably, the Bluetooth connection information includes a Bluetooth name and a connection password.

[0028] Preferably, the method for the mobile phone-side control App to establish a connection with the Hongmeng smart device is that the mobile phone-side control App establishes a Socket connection with the Hongmeng smart device via WiFi.

[0029] Compared with the prior art, the above technical solution of the present invention has the following beneficial technical effects:

[0030] (1) High security: Hongmeng smart devices can be registered by multiple people, and all security details are covered. Temporary unregistration must be approved by all registered users before it can be executed. Normal unregistration of the device will only take effect after all operators have normally unregistered it. The entire process is meticulous and meticulous, eliminating the possibility of safety hazards, so it can ensure high security throughout the operation process;

[0031] (2) High efficiency. The traditional listing model requires approval from multiple departments, which results in a long waiting time. During execution, the efficiency of exporting and processing problems may be low due to insufficient communication. The operation process of multiple listing operators can be realized in the management and control App. The operation process and operation interface are simple and easy to understand. The program execution process is fast and unambiguous, which fully reflects the efficiency.

[0032] (3) Low cost. The traditional listing system often requires multiple departments to shut down power and production to ensure the safety of the listing, which leads to considerable economic losses. The Hongmeng intelligent multi-person electronic listing system will not affect the production and operation of manufacturing enterprises, and has made significant improvements in administrative resource approval and execution operations, greatly reducing costs.

[0040] Embodiment 1: A Hongmeng intelligent multi-person electronic signage system proposed in the present invention includes a mobile phone management and control App and a Hongmeng intelligent device based on the OpenHarmony system;

[0041] The mobile management and control app is used to manage the connection with Hongmeng smart devices based on the OpenHarmony system, initiate operation requests (including but not limited to listing and temporary unlisting applications), receive approval information, and control device status;

[0042] Hongmeng smart devices based on the OpenHarmony system are used to undertake the tasks of data transmission, operation records, forwarding of approval applications and executing maintenance instructions, ensuring that the equipment can perform tasks according to the operator's needs.

[0043] The Hongmeng intelligent multi-person electronic signage system manages and controls the maintenance processes with mutual interlocking control. The mobile phone management and control App for the signage can perform near-field and far-field control, allowing all maintenance personnel to communicate and debug with each other. All maintenance processes are interlocked and controlled with each other. The mobile phone management and control App far-field control allows all maintenance personnel to communicate and debug with each other, thereby improving work efficiency and avoiding accidents.

[0044] In an optional embodiment, if Figure 1 As shown, the workflow of a Hongmeng intelligent multi-person electronic signage system proposed in this embodiment is as follows:

[0045] D01, such as Figure 2 As shown, when the Hongmeng smart device (hereinafter referred to as Hongmeng smart device) application based on the OpenHarmony system is enabled, the Socket service will be started according to the network environment of the Hongmeng smart device. Any maintenance operator holds the control device close to the NFC tag attached to the Hongmeng smart device, and the mobile control App reads the Bluetooth connection information of the Hongmeng smart device in the NFC. The Bluetooth connection information includes but is not limited to the Bluetooth name and connection password. After reading the Bluetooth connection information, the connection will be automatically made.

[0046] D02. After the mobile phone management and control App successfully connects to the Hongmeng smart device, the listing operation is performed in the operation interface. After the success, the listing operation is recorded in the current listing record table, and is prominently displayed in the visual interface of the Hongmeng smart device to prompt other listing operators (hereinafter referred to as the review operator), and a listing record is added to the Hongmeng smart device database, such as Figure 3 As shown in the LockInfo (listing information) object.

[0047] D03, such as Figure 4 As shown, after the maintenance operator is successfully posted, the Hongmeng smart device sends the socket connection method, that is, the IP and port number, to the mobile phone App. The mobile phone management and control App establishes a Socket connection with the Hongmeng smart device through WiFi.

[0048] It should be noted that the reason for connecting through WiFi socket is that Bluetooth cannot perform long-distance data transmission. Equipment maintenance often involves long distances, and the WiFi socket connection method can ensure the reliability of long-distance data transmission.

[0049] D04. After the mobile control App is connected to the Hongmeng smart device through a socket, the maintenance operator can submit temporary unblocking application information I through the mobile control App to verify the maintenance effect after completing the maintenance operation. The temporary unblocking application information I includes but is not limited to the reason for unblocking and the temporary unblocking operation time. The maintenance operator connects the Hongmeng smart device through the App to the timing diagram shown in the following figure. Figure 5 shown.

[0050] D05, such as Figure 6 As shown, after receiving the temporary unblocking application, the Hongmeng smart device forwards the application to the audit operator's mobile phone management and control App by sending a socket message. After receiving the application, the audit operator's mobile phone management and control App will emit obvious vibration and alarm sounds to remind the operator, and convert the temporary unblocking application information I into temporary unblocking application information II, and display the temporary unblocking application information II. The temporary unblocking application information II includes but is not limited to the applicant, the reason for the application and the temporary unblocking time.

[0051] D06. The review operator determines whether to approve the temporary release application based on his own maintenance situation:

[0052] If any one of the review operators disagrees, the application will be put on hold and remain in a waiting state;

[0053] If all the review operators agree to the temporary unblocking application at this time, the operator who submitted the temporary unblocking application will obtain the temporary unblocking permission through the mobile management App. At this time, the Hongmeng smart device will enter the temporary unblocking state and operate normally. The temporary unblocking will start counting down according to the applied unblocking time and execute D07.

[0054] D07. The maintenance operator who applies for temporary unhooking can obtain the operating status data of the Hongmeng smart device through the mobile control App. The operator sends instructions to the Hongmeng smart device by operating the mobile control App to check whether the operating status of the Hongmeng smart device is normal. After the countdown ends, the temporary unhooking state ends, and the maintenance operator loses the operation authority. If he wants to operate again, he needs to resubmit the application. The timing diagram of the maintenance operator applying for temporary hooking after listing is as follows Figure 7 shown.

[0055] D08. If the maintenance operator verifies that the maintenance operation is normal through temporary unhooking, the maintenance operator connects to the Hongmeng smart device via Bluetooth, and then unhooks through the normal unhooking mode of the mobile phone management App. After unhooking, the Hongmeng smart device deletes the listing information of the user. When the listing information of all devices is deleted, the device changes from the listing state to the normal working state.

[0056] In an optional embodiment, the Hongmeng smart device based on the OpenHarmony system is equipped with a Hongmeng smart device-side application. The Hongmeng smart device-side application is developed using OpenHarmonyArkTs. When the application is started, two services will be started, including: Service I and Service II.

[0057] Service I is used to handle BLE Bluetooth data services (such as Figure 3 The data object is encapsulated as a Bluetooth data transmission object (such as Figure 3 receiveBLEMessage object in the example);

[0058] Service II is used to process socket data objects (such as Figure 3 The data transmitted through the socket will be encapsulated into a Socket data transmission object (such as Figure 3 In the receiveTCPMessage object, the message queue mode is adopted in the data transmission process, and the weight of the modification instruction message is greater than the query instruction, which effectively solves the message blocking problem and provides real-time data transmission.

[0059] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
