Description

Technical Field

[0001] This invention relates to a vehicle remote monitoring system and method, specifically to a vehicle remote monitoring system and method based on the integration of BeiDou short message service and public network communication. Background Technology

[0002] In remote areas, sections of highways, border crossings, field operations, or emergency rescue sites, public network communication infrastructure often suffers from insufficient coverage or even complete absence. This prevents the timely and real-time transmission of critical information such as vehicle location and operational status to the monitoring center, posing a severe challenge to efficient vehicle dispatching and management, as well as safety assurance. Currently, most mainstream vehicle monitoring systems heavily rely on public network communication, such as mobile networks (covering 2G, 3G, 4G, and 5G). In environments without public networks, these systems are essentially unable to perform their vehicle monitoring functions properly. While some systems attempt to use BeiDou short message service for data transmission, the communication costs are calculated per message sent. In vehicle monitoring scenarios, to ensure real-time performance, frequent transmission of vehicle location and status information is necessary. Over time, the cumulative number of short messages sent per vehicle becomes substantial. As the scale of monitored vehicles continues to expand—for example, logistics companies often own hundreds or thousands of trucks—the monthly BeiDou short message communication costs become an unbearable expense, severely hindering the widespread application of this technology in large-scale vehicle monitoring. Therefore, developing a vehicle remote monitoring system and method that is suitable for environments without public networks and integrates BeiDou short message service with public network communication is of great practical significance. Summary of the Invention

[0003] This invention aims to construct a low-cost and highly reliable remote vehicle monitoring system and method, specifically addressing the challenge of vehicle monitoring in environments without a public network. By innovatively integrating BeiDou short message service with public network communication technology, it effectively solves the predicament of existing vehicle monitoring systems failing to function properly in environments without a public network, achieving real-time and accurate monitoring of vehicle location, status, and other information. This significantly improves vehicle management efficiency in special environments and provides a solid guarantee for the safe operation of vehicles.

[0004] This invention is achieved through the following technical solutions:

[0005] A remote vehicle monitoring method based on the integration of BeiDou short message service and public network communication includes the following steps:

[0006] S1: Information Collection and Packaging

[0007] Real-time vehicle information collection: The vehicle terminal uses a high-precision positioning module to accurately obtain the vehicle's geographical location information according to the set time interval, and at the same time, it uses a vehicle status collection module to comprehensively collect the vehicle's real-time operating status data.

[0008] Data Packaging and Processing: The data processing module packages the collected vehicle ID, precise timestamp, detailed location information, and rich vehicle status parameters according to a specific and rigorous data format to generate a data packet containing complete vehicle operation information for efficient subsequent transmission.

[0009] S2: Data packet sending

[0010] Communication environment assessment: The vehicle terminal intelligently assesses the communication status of the current environment in real time, detecting whether there is a usable public network signal. If a public network signal is detected, the public network data transmission process is executed; if no public network signal is detected, i.e., the environment is without a public network, the Beidou short message data transmission process is executed.

[0011] Public network data transmission: When the existence of a public network signal is confirmed, the packaged data packet follows the public network communication protocol and is stably sent to the data access gateway specially set up in the monitoring center through the public network;

[0012] BeiDou short message data transmission: In an environment without a public network, the packaged data packet is transmitted to the BeiDou short message communication module in the vehicle terminal. The module, in accordance with the strict communication protocol of the BeiDou system, accurately divides the data packet into several segments that meet the short message length limit, and then sends them to the BeiDou short message center platform in sequence.

[0013] S3: Continuous data reception: The monitoring center always maintains a state of listening to data. On the one hand, it continuously listens to data uploaded to the public network, and on the other hand, it continuously receives data synchronously pushed by the Beidou Short Message Center platform to ensure that no information from any source is missed.

[0014] Data parsing and processing: The monitoring center strictly parses the received public network data and data uploaded from the short message platform in accordance with the corresponding data protocols, accurately extracting key information about the vehicle, including ID, accurate data transmission time, detailed location data, and rich status data. Then, the parsed data is formatted and a data source field is added to identify whether the data was transmitted from the public network or Beidou short message. Finally, the unified data is sorted and merged according to the data transmission time, and the sorted and merged complete data is stored in the database for efficient subsequent querying and analysis.

[0015] S4: The monitoring center reads various vehicle information from the database in real time and displays the vehicle's trajectory, real-time location, and current operating status in an intuitive way on the monitoring interface. At the same time, it clearly shows whether the data currently displayed was collected and transmitted without a public network, based on the data source field, providing monitoring personnel with comprehensive and accurate vehicle operation information to facilitate their scientific decision-making.

[0016] In step S1, the obtained geographical location information of the vehicle includes latitude, longitude, and altitude.

[0017] In step S1, the real-time operating status data of the vehicle includes, but is not limited to, key parameters such as vehicle speed, fuel consumption, engine speed, and fault codes.

[0018] A vehicle remote monitoring system based on the integration of BeiDou short message service and public network communication includes a high-precision positioning module, a vehicle status acquisition module, a data processing module, a BeiDou short message communication module, a monitoring center, and a monitoring interface.

[0019] This invention solves the problem of communication without a public network, has significant cost advantages, and offers strong real-time performance and reliability. Attached Figure Description

[0020] Figure 1 This is a flowchart of the present invention. Detailed Implementation

[0021] like Figure 1 As shown, this invention provides a highly reliable and low-cost method for remote vehicle monitoring in a public network-free environment, specifically encompassing the following steps:

[0022] (I) Information Collection and Packaging

[0023] Real-time vehicle information collection: The vehicle terminal uses a high-precision positioning module to accurately obtain the vehicle's geographical location information such as latitude, longitude, and altitude according to the set time interval. At the same time, with the help of the vehicle status collection module, it comprehensively collects the vehicle's real-time operating status data, including but not limited to key parameters such as vehicle speed, fuel consumption, engine speed, and fault codes.

[0024] Data Packaging and Processing: The data processing module packages the collected vehicle ID, precise timestamp, detailed location information, and rich vehicle status parameters according to a specific and rigorous data format to generate a data packet containing complete vehicle operation information for efficient subsequent transmission.

[0025] (II) Data Packet Sending

[0026] Communication Environment Assessment: The vehicle-mounted terminal intelligently assesses the communication status of its current environment in real time, detecting the presence of available public network signals. If a public network signal is detected, the public network data transmission process is executed; if no public network signal is detected, i.e., the environment is without a public network, the BeiDou short message data transmission process is executed.

[0027] Public network data transmission: When the presence of a public network signal is confirmed, the packaged data packet will follow the public network communication protocol and be stably sent to the data access gateway specially set up in the monitoring center through the public network, ensuring that the data can be transmitted to the monitoring center quickly and accurately.

[0028] BeiDou short message data transmission: In environments without a public network, the packaged data packets are transmitted to the BeiDou short message communication module in the vehicle terminal. This module, based on the strict communication protocol of the BeiDou system, precisely divides the data packets into several segments that conform to the short message length limit, and then sends them sequentially to the BeiDou short message center platform, thus achieving data transmission in environments without a public network.

[0029] (III) Data Reception and Analysis

[0030] Continuous data reception: The monitoring center maintains a constant state of data monitoring, continuously listening to data uploaded to the public network on the one hand, and continuously receiving data synchronously pushed by the Beidou Short Message Center platform on the other hand, to ensure that no information from any source is missed.

[0031] Data parsing and processing: The monitoring center rigorously parses the received public network data and data uploaded from the short message platform according to the corresponding data protocols, accurately extracting key information such as vehicle ID, precise data transmission time, detailed location data, and rich status data. Next, the parsed data undergoes format standardization, and a data source field is added to identify whether the data was transmitted via the public network or BeiDou short message service. Finally, the standardized data is sorted and merged based on the data transmission time, and the sorted and merged complete data is stored in the database for efficient subsequent querying and analysis.

[0032] (iv) Vehicle monitoring

[0033] The monitoring center reads various vehicle information from the database in real time and displays the vehicle's trajectory, real-time location, and current operating status in an intuitive way on a specially designed monitoring interface. Simultaneously, the data source field clearly indicates whether the currently displayed data was collected and transmitted without a public network connection, providing monitoring personnel with comprehensive and accurate vehicle operation information to facilitate informed decision-making.

[0034] This invention has the following characteristics:

[0035] (I) Intelligent dual-channel switching mechanism

[0036] It automatically detects the strength of the public network signal. When there is a signal, it prioritizes using the free / low-cost mobile network to transmit data. When there is no signal, it immediately switches to Beidou short message transmission.

[0037] (II) Hybrid Data Fusion Technology

[0038] By merging data from multiple sources, the positioning points transmitted by Beidou and the driving trajectory transmitted by the public network are automatically connected to form a complete route.

[0039] The specific effects of this invention are:

[0040] (I) Solving the problem of communication without a public network

[0041] By leveraging the short message communication function of BeiDou, the limitations of public network communication have been successfully overcome. Even when vehicles are traveling in remote mountainous areas or vast wilderness areas where public network signals are difficult to cover, remote monitoring can still be achieved, greatly expanding the application scope of vehicle monitoring systems and providing reliable technical means for vehicle management in various complex environments.

[0042] (ii) Significant cost advantages

[0043] A flexible communication strategy is adopted, prioritizing the use of the relatively low-cost public network for data transmission in areas with public network coverage; and enabling BeiDou short message communication in environments without public network access. This intelligent integration approach effectively reduces the construction and operation costs of the vehicle remote monitoring system, making large-scale deployment possible and providing numerous enterprises and users with an economical and feasible vehicle monitoring solution.

[0044] (III) High real-time performance and reliability

[0045] Through precise information collection, intelligent communication method selection, and efficient data processing, this invention can acquire vehicle location and status information in real time. Whether in a public network environment or an environment without a public network, it ensures the accuracy and continuity of data transmission, providing strong data support for vehicle safety management and greatly improving vehicle safety and management efficiency in various environments.
