Description

Technical Field

[0001] This invention relates to the field of intelligent management technology for construction machinery, and in particular to a method for remote monitoring and lock management of construction machinery. Background Technology

[0002] Currently, in the field of traditional construction machinery management, there is a common technical bottleneck: the inability to obtain real-time operating data. Once equipment malfunctions or is used abnormally (such as improper operation, non-payment of debts, or theft), the lack of complete and traceable operational history makes it difficult to conduct effective post-event accountability and analysis. At the same time, existing technical means heavily rely on manual on-site inspections for equipment maintenance and fault diagnosis, which is not only slow in response and costly in operation and maintenance, but also extremely inefficient.

[0003] Although some remote monitoring systems have emerged in the existing technology, these systems usually have significant drawbacks: their security is weak and they are vulnerable to attacks; the data transmission links are unstable, leading to the loss or delay of critical information; and their functional design is limited, only enabling basic data viewing and lacking comprehensive management capabilities that integrate real-time monitoring, historical tracing, intelligent early warning, and remote intervention (such as secure and reliable locking / unlocking).

[0004] Therefore, existing technical solutions cannot meet the urgent needs of modern construction machinery for efficient, safe, intelligent and refined management throughout its entire life cycle, and an innovative technical solution is urgently needed to solve the above pain points. Summary of the Invention

[0005] The purpose of this invention is to provide a method for remote monitoring and locking of construction machinery, which solves the problems of insufficient security, unstable data transmission, limited functionality, and lack of effective remote locking and operation traceability in existing remote monitoring systems for construction machinery, and realizes efficient, safe, and intelligent management of the entire life cycle of the equipment.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows:

[0007] A method for remote monitoring and lock management of construction machinery, characterized in that it includes: collecting operating data on the CAN bus of the equipment controller in real time through a 4G full-network terminal module installed on the construction machinery;

[0008] The 4G terminal module transmits the operating data to a cloud server deployed in a secure cloud environment via the MQTT protocol in encrypted form.

[0009] After the cloud server performs protocol conversion on the data, it stores it in an Oracle database;

[0010] The remote operation center accesses the cloud server via a public IP address to view real-time and historical operating data of the equipment.

[0011] The remote operation center issues lock / unlock commands, which are transmitted to the device controller via the cloud server and 4G terminal module to complete the remote lock or unlock operation.

[0012] As an improvement, the 4G full-network compatible terminal module supports both patch SIM cards and physical external SIM cards, and can choose the appropriate mode based on the signal quality of the operator in the device's location.

[0013] As an improvement, the 4G terminal module has reserved 2 CAN interfaces and 2 RS232 interfaces to support data interaction with various types of engineering machinery controllers and vehicle sensors;

[0014] The module is equipped with 8MRAM and supports a wide voltage power supply of 8-36V, making it suitable for different electrical environments of engineering machinery.

[0015] As an improvement, the cloud server uses Windows Server 2008 R2 or later operating system, with a minimum configuration of: dual-core CPU, 200G hard disk (100G C drive, 100G D drive), 8G memory, 4M network bandwidth, equipped with a fixed public IP address and communication ports can be opened as needed.

[0016] As an improvement, the remote operation center has equipment file management function, which supports the addition, modification, deletion and full-dimensional file maintenance of equipment information, and can be associated with asset data such as equipment model, manufacturer, installation location, and maintenance information.

[0017] As an improvement, the remote operation center supports real-time operating status query, historical operating status query, and raw data query. It can be filtered and retrieved by time period, device ID, and data type, and retains complete data of the entire equipment operation cycle.

[0018] As an improvement, all locking and unlocking commands are logged in an unalterable manner, including the person who issued the command, the time, the device number, and the execution result, making the entire operation traceable.

[0019] As an improvement, the system adopts role-based hierarchical permission control, supporting region management, role management, and user management. It can assign operation permissions according to geographical partitions and role types, achieving fine-grained permission isolation.

[0020] As an improvement, dual verification is required before the lock / unlock command is issued: user login credentials verification and target device operation permission verification. The command transmission adopts end-to-end encryption to ensure control security.

[0021] As an improvement, the system supports two operation and maintenance modes: customer-owned server deployment + our program maintenance mode; and our cloud hosting + billing based on the number of devices mode. It also has automatic early warning for abnormal usage and unattended management capabilities.

[0022] The beneficial effects of this invention are: real-time collection and uploading of equipment operating data through 4G terminals, support for real-time and historical data queries by remote operation centers, reduction of reliance on on-site manual inspections, improvement of operation and maintenance efficiency, and support for unattended management.

[0023] It provides secure and reliable remote locking / unlocking functions, which can be used to handle risks such as equipment arrears or theft. Command transmission uses end-to-end encryption and undergoes dual verification (user credentials and device permissions) before being issued, ensuring control security. All operations are logged in an immutable manner, enabling full traceability.

[0024] The system has the ability to automatically warn of abnormal usage, and through refined role-based hierarchical permission control (supporting region, role, and user management), it achieves intelligent and refined management of devices;

[0025] The system design is flexible and highly adaptable: the 4G terminal module supports dual SIM card mode to adapt to signals in different regions, and reserves multiple interfaces (CAN, RS232) to be compatible with multiple types of device controllers and sensors. It also supports wide voltage power supply and can adapt to different electrical environments of engineering machinery.

[0026] Flexible deployment modes: The system supports two operation and maintenance modes—deployment on the customer's own server (program maintained by the patent holder) or cloud hosting by the patent holder (billed according to the number of devices), to meet the needs of different customers;

[0027] Comprehensive data management: It can completely retain data throughout the entire lifecycle of equipment operation (real-time, historical, and raw data) and supports multi-dimensional equipment file management, providing a solid data foundation for equipment asset management, fault analysis, and performance optimization;

[0028] Therefore, it effectively overcomes the problems in traditional engineering machinery management, such as the inability to obtain working condition data in real time, the difficulty in tracing responsibility after failure or abnormal use, and the low efficiency and high cost caused by relying on manual inspection. At the same time, it also makes up for the shortcomings of existing remote monitoring systems in terms of security, data transmission stability, single function, and lack of effective remote intervention and operation traceability capabilities.

[0032] To make the content of this invention easier to understand, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0033] like Figures 1 to 3 As shown, a remote monitoring and lock management method for construction machinery is characterized by comprising: real-time acquisition of operating condition data on the CAN bus of the equipment controller via a 4G full-network terminal module installed on the construction machinery; the 4G terminal module encrypting and transmitting the operating condition data to a cloud server deployed in a secure cloud environment via the MQTT protocol; the cloud server performing protocol conversion on the data and storing it in an Oracle database; a remote operation center accessing the cloud server via a public IP address to view the real-time and historical operating condition data of the equipment; and the remote operation center issuing lock / unlock commands, which are transmitted to the equipment controller via the cloud server and the 4G terminal module to complete the remote lock or unlock operation.

[0034] The 4G full-network compatible terminal module supports both patch SIM cards and physical external SIM cards, allowing for independent selection and adaptation based on the signal quality of the local operator. The 4G terminal module reserves two CAN interfaces and two RS232 interfaces, supporting data interaction with various types of engineering machinery controllers and vehicle sensors. The module is equipped with 8MB of RAM and supports a wide voltage power supply of 8-36V, adapting to different electrical environments of engineering machinery.

[0035] The cloud server uses Windows Server 2008 R2 or later operating system, with a minimum configuration of: dual-core CPU, 200GB hard drive (100GB C drive, 100GB D drive), 8GB RAM, 4Mbps network bandwidth, and a fixed public IP address with the ability to open communication ports as needed. The remote operation center has equipment file management functions, supporting the addition, modification, and deletion of equipment information, as well as full-dimensional file maintenance. It can associate asset data such as equipment model, manufacturer, installation location, and maintenance information. The remote operation center supports real-time operating status queries, historical operating status queries, and raw data queries, and can filter and search by time period, equipment ID, and data type, completely retaining equipment operation lifecycle data.

[0036] All locking and unlocking commands are logged in an immutable manner, including the sender, time, device number, and execution result, ensuring full traceability. The system employs role-based hierarchical access control, supporting region, role, and user management. Operation permissions can be assigned based on geographical partitions and role types, achieving fine-grained access control. Locking / unlocking commands require dual verification before issuance: user login credentials verification and target device operation permission verification. Command transmission uses end-to-end encryption to ensure control security. The system supports two operation and maintenance modes: customer-owned server deployment + our program maintenance mode; our cloud hosting + pay-per-device model. It also features automatic alerts for abnormal usage and unattended management capabilities.

[0037] During implementation, a 4G full-network compatible terminal module must first be installed on the construction machinery. This module collects real-time operating data from the equipment controller via the CAN interface and uploads it to a cloud server deployed in a secure cloud environment using the MQTT protocol. After protocol conversion, the cloud server stores the data in an Oracle database. The remote operation center accesses the server via a public IP address to query real-time and historical operating data of the equipment, manage equipment files, and implement hierarchical access control based on region and role. When locking or unlocking is required, the operation center issues a command after dual verification (user credentials and equipment permissions). The command is transmitted to the terminal module via end-to-end encryption and is ultimately executed by the equipment controller. All commands are logged in an immutable manner, thus enabling secure, traceable, and highly efficient remote equipment management and risk control in various operation and maintenance modes, including unattended operation and deployment on customer-owned servers.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
