[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0042] The terms "including" and "having" and any variations thereof mentioned in the embodiments of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but may optionally include other steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0043] Existing trailer weighing systems are all connected by wires to complete the system's power supply, signal transmission and other tasks. During the trailer replacement process, the driver needs to plug and unplug the cable connector and the air pipe connector. If the vehicle is equipped with a weighing system, the weighing system must also be plugged and unplugged. Long-term operation will cause irreversible damage to the waterproof and durable performance of the system. Therefore, the existing technology has a technical problem that the weighing system is greatly damaged when replacing the trailer.

[0044] Based on this, the embodiments of the present application provide a matching method, system and device for a trailer weighing system, through which the technical problem of the existing technology that the weighing system is seriously damaged when replacing the trailer can be alleviated.

[0045] The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0046] Figure 1 The present invention provides a flowchart of a method for matching a trailer weighing system. The method can be applied to a matching system for a trailer weighing system. The trailer weighing system is arranged on the trailer, and the trailer weighing system is connected to the front of the trailer by wireless. Figure 1 As shown, the method includes:

[0047] Step S110, in response to the unbinding instruction for the vehicle head, the vehicle head is controlled to be disconnected from the first trailer weighing system.

[0048] Exemplarily, the initial state is that the front of the trailer is connected to the first trailer. When the trailer needs to be changed, the user can operate the touch display terminal (i.e., the central control screen) at the front end of the trailer, for example, click the unbinding button in the touch display terminal to quickly unbind the binding between the front of the trailer and the weighing system of the first trailer.

[0049] Step S120, in response to the binding instruction for the vehicle head, determining a second trailer weighing system to be bound to the vehicle head within a preset range.

[0050] For example, when the trailer head is connected to the second trailer and the trailer replacement operation is completed, the user can click the binding button in the touch display terminal to enable the matching system to determine the second trailer weighing system to be bound and connected within the preset range of the trailer head. In actual applications, confirmation can be made through a variety of restrictions, for example, determining the nearest trailer weighing system within the preset range as the second trailer weighing system, or determining the trailer weighing system in the preset range that is in a state of being connected as the second trailer weighing system.

[0051] Step S130, controlling the locomotive to connect with the second trailer weighing system so that the locomotive matches the second trailer weighing system.

[0052] Exemplarily, after determining the second trailer weighing system, the matching system of the trailer weighing system can control the front end of the trailer to wirelessly connect with the second trailer weighing system to achieve automatic matching and binding between the front end and the second trailer weighing system.

[0053] In the embodiment of the present application, the trailer head and the trailer weighing system are connected wirelessly. When the head needs to be untied from the first trailer, the user first issues an unbinding instruction to the system for the head and the first trailer weighing system, and the head and the first trailer weighing system can be quickly untied. Then, when the user issues a binding instruction, the system can search within the preset range of the head, determine the second trailer weighing system to be bound, and then control the head to connect with the second trailer weighing system to match the head with the second trailer weighing system. This solution implements a series of unbinding and binding processes wirelessly, without worrying about the wear and tear of the physical structure components caused by manual operation, ensuring that the data is still accurate after the replacement, alleviating the technical problem of greater damage to the weighing system when replacing the trailer in the prior art, and all operations can be completed by the driver alone, reducing the pressure of manual operation and effectively improving the efficiency of replacement.

[0054] The above steps are described in detail below.

[0055] In some embodiments, after the first trailer weighing system is untied from the vehicle head, the state of the first trailer weighing system may be changed to avoid misconnection. As an example, after the above step S110, the method may further include the following steps:

[0056] Step a), in response to the vehicle head being disconnected from the first trailer weighing system, controlling the first trailer weighing system to enter an offline state.

[0057] Exemplarily, when the trailer head is disconnected from the first trailer weighing system, the first trailer weighing system may be powered off or logically placed in an unconnectable state, thereby causing the first trailer weighing system to enter an offline state.

[0058] By making the system respond to the disconnection between the vehicle head and the first trailer weighing system and controlling the first trailer weighing system to enter an offline state, the disconnected first trailer weighing system will not be detected by the trailer head, thereby avoiding the situation where the trailer head and the first trailer weighing system are connected again and cause a misconnection.

[0059] In some embodiments, each trailer weighing system has a unique device number. After the trailer connection is completed, the system can perform a data calibration on the entire vehicle to avoid errors caused by data asynchrony. As an example, the above step S130 may specifically include the following steps:

[0060] Step b), controlling the connection between the vehicle head and the second trailer weighing system.

[0061] Step c), in response to the vehicle head being connected to the second trailer weighing system, identifying the serial number of the second trailer weighing system.

[0062] Step d), based on the serial number of the second trailer weighing system, calibrate the data of the locomotive head and the second trailer weighing system to match the locomotive head with the second trailer weighing system.

[0063] For example, each trailer and its weighing system has a unique equipment number. When the front of the trailer is connected to the weighing system of the second trailer, the system can automatically identify the new trailer and its weighing system. Since the equipment number changes, it will trigger the server to generate a trailer replacement event, start the automatic calibration command, and perform a data calibration on the entire trailer.

[0064] By making the system control the connection between the locomotive and the second trailer weighing system and identifying the number of the second trailer weighing system, the locomotive and the second trailer weighing system are calibrated based on the number of the second trailer weighing system to match the locomotive and the second trailer weighing system, thereby ensuring data synchronization and the accuracy of the weighing system.

[0065] Based on the above steps b), c) and d), the status data of all trailer weighing systems are stored on the server, and the matching system can obtain the corresponding status data from the server, thereby realizing data calibration. As an example, the server stores the status data of the second trailer weighing system; the above step d) may specifically include the following steps:

[0066] Step e): based on the serial number of the second trailer weighing system, obtaining the status data of the second trailer weighing system from the service end.

[0067] Step f), calibrating the data of the entire vehicle based on the status data of the second trailer weighing system.

[0068] For example, the matching system can obtain the status data corresponding to the second trailer weighing system from the server based on the number of the second trailer weighing system. The automatic calibration command initiated by the server actually sends the calibration data such as the empty, fully loaded, and fully loaded net weight of the second trailer recorded in the database and writes it into the touch display terminal of the trailer head. Therefore, the data of the whole vehicle is calibrated based on the status data of the second trailer weighing system to match the head with the second trailer weighing system, ensuring data synchronization and the accuracy of the weighing system.

[0069] Based on the above steps e) and f), the data calibration content may include multiple types. By including multiple types of data calibration content, the functions are enriched, and accurate matching of the trailer and the head of the vehicle is achieved. As an example, the data calibration content includes any one or more of the following:

[0070] The real-time weight of the entire vehicle, the net weight of the entire vehicle, the tare weight of the entire vehicle, the real-time position of the entire vehicle, the driving trajectory of the entire vehicle, the task monitoring of the entire vehicle, and the system settings of the entire vehicle.

[0071] For example, when the server writes data into the touch display terminal on the front of the trailer and completes the data calibration, the touch display terminal on the front of the trailer can display the current real-time weight of the entire vehicle, and can switch between net weight, tare weight, etc.; it can also display the real-time location to display the current vehicle positioning position using a Geographic Information System (GIS) map; it can also display trajectory playback, and users can select a time range to view the vehicle trajectory; it can also display task monitoring, and users can view the progress of the currently executed tasks; it can also display system settings, that is, setting basic information such as vehicle tare weight, load unbinding, binding, and wireless settings, etc.

[0072] In some embodiments, the trailer weighing system can be connected to the trailer head through a variety of wireless protocols. As an example, the trailer weighing system is connected to the head through the LoRa wireless protocol.

[0073] For example, the LoRa wireless protocol has many advantages. The sensitivity of reception is improved and power consumption is reduced. The link budget of up to 157db enables its communication distance to reach 15 kilometers (related to the environment). Its receiving current is only 10mA and the sleep current is 200nA, which greatly delays the battery life. The gateway / concentrator based on this technology supports parallel processing of multiple channels and multiple data rates, and the system capacity is large. The system based on the terminal and concentrator / gateway can support ranging and positioning.

[0075] The trailer end includes a weighing module, a first wireless module, a power protection module and a trailer battery, and the first wireless module is connected to the weighing module and the trailer battery respectively; the trailer head end includes a data communication module, a second wireless module and a touch display terminal; the trailer end and the trailer head end realize wireless connection and data transmission through the first wireless module and the second wireless module;

[0076] The weighing module is used to weigh the trailer;

[0077] The trailer battery is used to provide power to the first wireless module and the weighing module;

[0078] The power protection module is used to convert the electric energy provided by the trailer battery into electric energy that meets the working voltage of the first wireless module and the weighing module;

[0079] The data communication module is used to realize data transmission between the trailer head end and the service end;

[0080] The touch display terminal is used to display information and receive touch commands.

[0081] In practical applications, such as Figure 2 As shown, the power protection module is connected to the trailer power supply externally, converting the high voltage 24V into 5V for use by the first wireless module and the weighing module, and has a power protection function, always detecting the external power supply, and disconnecting the external power supply when the low voltage protection is triggered. The first wireless module can be connected to the weighing module via the RS485 bus for wireless forwarding, and forwarding the trailer weighing system data to the front end of the trailer via the LoRa wireless protocol. The touch display terminal at the front end of the trailer can be equipped with the Android 8.1 native operating system. The data communication module is used for data communication, and the data transmission between the front end of the trailer and the server can be completed through the built-in 4G communication module. The second wireless module realizes data transmission with the first wireless module through the LoRa wireless protocol. The touch display terminal is used to realize human-computer interaction and data display.
