Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a control system integration device and method based on a comprehensive gateway. Background Technology

[0002] Currently, in the field of special-purpose modified vehicles, after leaving the factory, vehicles need to be equipped with various special control systems according to specific operational needs (such as fire control for fire trucks, hydraulic control for engineering vehicles, and temperature control for refrigerated trucks). These control systems are usually equipped with independent displays and control panels. When modifying existing special-purpose modified vehicles, the displays and control panels of each added control system (such as hydraulic control system, temperature control system, and operation monitoring system) need to be independently installed on the dashboard in the driver's cab. This causes the driver to frequently switch between different terminal displays and operate on different control panels during operation, resulting in low operational efficiency.

[0003] In conclusion, improving the control efficiency of control systems installed on specially modified vehicles is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0036] Figure 2 This is a schematic diagram of another control system integration device based on a comprehensive gateway, provided as an embodiment of this application. Detailed Implementation

[0037] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. This application provides a control system integration device and method based on a comprehensive gateway, relating to the field of vehicle technology. The above are merely examples and do not limit the application field of the methods and devices provided in this application.

[0038] Currently, in the field of special-purpose modified vehicles (specially modified vehicles), after leaving the factory, vehicles need to be equipped with various special control systems according to specific operational needs (such as fire control for fire trucks, hydraulic control for engineering vehicles, and temperature control for refrigerated trucks). These control systems are usually equipped with independent displays and operating panels. Currently, the industry faces the following key technical challenges in the modification of specially modified vehicles:

[0039] (1) The operating terminals are scattered, resulting in a poor user experience:

[0040] When modifying existing special-purpose vehicles, the displays and control panels of various added control systems (such as hydraulic control systems, temperature control systems, and operation monitoring systems) need to be independently installed on the IP console (instrument panel) in the driver's cab, resulting in the IP console being cluttered with various terminal devices. During operation, the driver needs to frequently switch between the displayed information of different terminals and operate on different control panels, which not only distracts the driver and increases the complexity of operation, but may also cause safety hazards due to untimely operation.

[0041] (2) The interface and protocol are incompatible, making integration difficult:

[0042] Due to the lack of standardized technical standards among different control system suppliers, the hardware interfaces (such as serial ports, CAN interfaces, RS-485, and Ethernet ports) of each control system vary, and their data communication protocols (such as custom serial port protocols, CANopen protocols, and Modbus protocols) are incompatible. The original vehicle's infotainment system only supports the manufacturer-defined interfaces and protocols, and cannot directly interact with the aftermarket control system. This results in the modified control system being unable to display information on the original vehicle's screen or provide alarm prompts through the vehicle's horn (original audio system), necessitating the addition of a separate display and alarm device.

[0043] (3) The wiring is complex and the renovation cost is high:

[0044] To enable power supply, data transmission, and alarm functions for each independent control system, a large number of cables (such as power lines, signal lines, and audio lines) need to be laid inside and outside the driver's cab during the modification process. This not only increases wiring time and labor costs but may also lead to difficulties in later maintenance due to the chaotic cable layout (such as the difficulty in troubleshooting cable faults). At the same time, the procurement costs of independent displays, control panels, and alarm devices further increase the overall modification cost of the specially modified vehicle and reduce the market competitiveness of the modification scheme.

[0045] The inventors, through research, proposed the technical solution of this application. This integrated control system device based on a comprehensive gateway includes: a vehicle-mounted infotainment system, a comprehensive gateway, and a control system. The vehicle-mounted infotainment system is connected to the comprehensive gateway, and the control system is also connected to the comprehensive gateway. The vehicle-mounted infotainment system sends control commands to the comprehensive gateway, which in turn sends the control commands to the control system. The control system then executes the corresponding control operations based on the control commands. In this way, the vehicle-mounted infotainment system can be directly controlled via the comprehensive gateway, thereby improving the control efficiency of the control system installed on specially modified vehicles.

[0046] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, and not all of them. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present application. It should be noted that, for ease of description, only the parts related to the invention are shown in the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of the present application can be combined with each other.

[0047] First, it should be noted that the embodiments of this application combine methods and apparatus, and provide a unified exemplary description of the methods and apparatus of this application. Figure 1 This application provides a schematic diagram of a control system integration device based on a comprehensive gateway, wherein the control system integration device 100 includes:

[0048] The system includes a vehicle-mounted infotainment system 110, an integrated gateway 120, and a control system 130. The vehicle-mounted infotainment system 110 is connected to the integrated gateway 120, and the integrated gateway 120 is connected to the control system 130, enabling the connection between the vehicle-mounted infotainment system 110 and the control system 130 through the integrated gateway 120. In response to a control operation performed by the vehicle operator on the vehicle-mounted infotainment system 110, the system generates a control command for the control system 130 based on the control operation. The vehicle-mounted infotainment system 110 then sends this control command to the integrated gateway 120, which in turn sends it to the control system 130. The control system 130 then performs the control operation based on the control command.

[0049] Similarly, the control system 130 can generate control data, such as operational data like hydraulic pressure, temperature, load, and work progress. The control system 130 uploads the control data to the integrated gateway 120, which then uploads it to the vehicle infotainment system 110. Finally, the vehicle infotainment system 110 displays the data based on the control data.

[0050] Specifically, such as Figure 2 As shown, Figure 2 The schematic diagram of another control system integration device based on a comprehensive gateway provided in this application embodiment shows that the comprehensive gateway 120 includes: a protocol conversion module 121, a data processing module 122, a communication interface module 123, an alarm linkage module 124, and a power supply module 125.

[0051] The communication interface module 123 integrates a 485 bus interface, a serial port, a CAN bus interface, and an Ethernet port (supporting TCP / IP protocol), which can cover the hardware interface types of the mainstream control systems 130 in the current special vehicle modification market, and realize the physical connection with each added control system 130.

[0052] The protocol conversion module 121 has a built-in protocol parsing and conversion engine, which pre-stores and supports dynamic updates of the communication protocols of mainstream retrofit control systems 130, such as Modbus-RTU, CANopen, RTSP, and custom operation control protocols. It can convert heterogeneous data output by various control systems 130, such as operation parameters, fault codes, and status signals, into unified standard protocol data, which is convenient for display and operation by the vehicle's infotainment system 110.

[0053] The data processing module 122 uses a Cortex-A55 high-performance microprocessor to receive real-time data from each control system 130, perform data verification, filtering and integration, such as removing invalid data and prioritizing data. According to the request instructions from the vehicle control unit 110, it sends the processed data to the vehicle control unit 110. At the same time, it receives operation instructions issued by the vehicle control unit 110, converts them into instruction formats that can be recognized by the corresponding control system 130 and sends them to the target control system 130.

[0054] The alarm linkage module 124 has a built-in alarm logic processing unit, which can generate standardized alarm commands based on the fault signals sent by each control system 130, such as excessive parameters or equipment abnormalities, and notify the vehicle unit 110. The vehicle unit 110 then controls the vehicle horn to emit the corresponding alarm prompt sound.

[0055] The power module 125 supports wide voltage (9V~36V) input and has overvoltage, overcurrent and short circuit protection functions to ensure that the integrated gateway 120 works stably in the complex power supply environment of the vehicle.

[0056] Based on the above devices, the various control systems 130 installed on the modified vehicle, such as the hydraulic system and temperature control system, can be connected to the communication interface module 123 of the integrated gateway 120 through their corresponding communication interfaces (485 / CAN / Ethernet). The integrated gateway 120 can be connected to the vehicle's infotainment system 110 through an Ethernet port or CAN interface. Through the configuration interface of the integrated gateway 120, the corresponding communication protocol can be selected for each installed control system 130, completing the protocol adaptation between the integrated gateway 120 and each control system 130. The integrated gateway 120 collects the operating data (such as hydraulic pressure, temperature, load, and work progress) of each control system 130 in real time through the protocol conversion module 121. After being integrated by the data processing module 122, the data is sent to the vehicle's infotainment system 110. After receiving the data, the central control screen 110 displays it on the preset APP interface.

[0057] The operator initiates an operation command to a certain control system 130 through the vehicle's infotainment system 110 (such as adjusting hydraulic pressure or setting a temperature threshold). The vehicle's infotainment system 110 sends the operation command to the integrated gateway 120. After receiving the operation command, the integrated gateway 120 converts it into an instruction format that the corresponding control system 130 can recognize through the protocol conversion module 121 and sends it to the target control system 130.

[0058] When a certain control system 130 malfunctions (such as excessive temperature or abnormal pressure), the system sends a fault signal to the integrated gateway 120. After the alarm linkage module 124 of the integrated gateway 120 identifies the fault type, it generates a standardized alarm command and displays a fault alarm pop-up window on the vehicle's infotainment system (displaying the fault system name and fault cause) and controls the vehicle's horn to emit the corresponding alarm prompt sound.

[0059] If a new control system 130 is needed in the future, simply connect the new control system 130 to the idle communication interface of the integrated gateway 120 and configure the corresponding communication protocol in the integrated gateway 120. No hardware or software modifications to the vehicle system are required, thus enabling flexible system expansion.

[0060] In this embodiment, the integrated control system device based on a comprehensive gateway includes: a vehicle-mounted infotainment system, a comprehensive gateway, and a control system. The vehicle-mounted infotainment system is connected to the comprehensive gateway, and the control system is also connected to the comprehensive gateway. The vehicle-mounted infotainment system sends control commands to the comprehensive gateway, which in turn sends the control commands to the control system. The control system then executes the corresponding control operations based on the control commands. This allows the vehicle-mounted infotainment system to be directly controlled via the comprehensive gateway, thereby improving the control efficiency of the control system installed on the modified vehicle.

[0061] The above describes the control system integration device and method based on a comprehensive gateway provided in the embodiments of this application. The following describes the control system integration device and method based on a comprehensive gateway in conjunction with specific application scenarios.

[0062] Taking specially modified police enforcement vehicles as an example, the equipment that needs to be installed includes:

[0063] The following equipment is installed on the exterior and interior of the vehicle: 4 cameras (to ensure no blind spots in front, behind, left, and right, for law enforcement recording), police lights, searchlights, sirens, lighting, radio, loudspeaker, command display screen, and vehicle-mounted emergency power supply (inverter).

[0064] The control systems that need to be installed on the specially modified vehicles are a video surveillance system and a police control system:

[0065] For video surveillance systems, the method is as follows:

[0066] The video surveillance system establishes a hardware connection with the integrated gateway's communication interface module via its network port. The data processing module handles login authentication, connection establishment (port allocation, channel number allocation, and stream parameter configuration), and data verification. The protocol conversion module reads and parses video streams, audio streams, and real-time PTZ data using the video surveillance system's protocol, converting them into a unified standard multimedia RTSP protocol (a custom protocol between the integrated gateway and the vehicle's infotainment system). This enables display and operation on the vehicle's infotainment system, including real-time screen display, video playback, and PTZ control. The alarm linkage module, with its built-in alarm logic processing unit, generates standardized alarm commands (using a custom protocol between the integrated gateway and the vehicle's infotainment system) based on fault signals (such as offline or equipment malfunction) sent by the video control system. This notifies the vehicle's infotainment system of the alarm (abnormal notification) and emits a corresponding alarm tone through the vehicle's loudspeaker.

[0067] For police control systems, the method is as follows:

[0068] The police control system and the integrated gateway communication interface module establish a hardware connection via the RS-485 interface. The data processing module is responsible for establishing the connection, including data CRC verification, handshake, and data transmission and reception. The protocol conversion module reads and parses the control switch status (such as siren lights on or off) and operating status (inverter output power, remaining power, etc.) of peripheral devices through the police control system protocol, and converts it into a unified standard universal control protocol (integrated gateway and vehicle-mounted unit custom protocol). The vehicle-mounted unit displays and operates the information, including the ON / OFF status and operating status of each peripheral device (siren lights, lighting, etc.) and the inverter status. The alarm linkage module has a built-in alarm logic processing unit. Based on the fault signals sent by the police control system (such as offline, equipment abnormality), it generates standardized alarm commands (integrated gateway and vehicle-mounted unit custom protocol), notifies the vehicle-mounted unit of the alarm (abnormal prompt), and emits the corresponding alarm sound through the vehicle's horn.
