[0044] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0045] like Figure 1 As shown, a light control method for a combine harvester working device includes:

[0046] Step 1, when the light CAN panel of the combine harvester is not faulty, receiving and analyzing the switch quantity information on the light CAN panel;

[0047] Step 2: Control the light color through the light driving unit according to the analysis result;

[0048] Step 3: Repair the fault according to the light color.

[0049] In some possible implementations, integration, embedded systems, and the maturity of LAN on-board control unit (BCM) data bus technology have made the integration of agricultural machinery electronic control a development trend of agricultural machinery electronic control technology; intelligence, the application of intelligent technology and computer technology, the bus switch with logic function, the on-board control unit and the lighting drive unit (BCM) are connected, and the whole vehicle lighting execution unit is connected to form an integrated control system; networking, as more and more electronic control devices are used in agricultural machinery, data communication between on-board electronic equipment has become more and more important, and an agricultural machinery electronic control system based on a distributed control system is very necessary, and a large amount of data can be exchanged quickly; electronic control technology has been widely used in the field of agricultural machinery, greatly improving the comprehensive performance of agricultural machinery, and making agricultural machinery have great progress in safety, comfort and other aspects.

[0050] It should be noted that the present invention discloses a light control system and method for a harvester working device based on CAN bus network technology. Figure 3 , including an intelligent display terminal (which can be a display screen), an on-board control unit (vehicle control unit), a lighting drive unit (BCM), and a lighting control module (the lighting CAN panel of the combine harvester). The lighting control module includes: a bus lighting control panel and an auxiliary function control panel.

[0051] The light driving unit, as the control object of the CAN bus network, is composed of various lights inside and outside the vehicle body. The control of the lights that need to be realized can be communicated with the control unit through CAN signals by the bus light control panel and the auxiliary function control panel. The vehicle control unit sends the processed logical functions to the light driving unit (BCM) through the CAN bus, and controls the lighting and extinguishing of each functional light through the light driving unit (BCM).

[0052] All lights are controlled by switches. The bus light control panel is an output signal and is installed in various areas of the vehicle. The light control module is installed in the cab. The pattern clearly marks the position and function of each light of the vehicle, which is convenient for the driver to operate and use. The work light can be lit with one press. The bus light control panel controls the top front work light, front panel light, stubble light, cutting table light, warning light and rear work light, side wing maintenance light, grain unloading light, and the bus switch of the cleaning room maintenance light is arranged near the maintenance light, which controls the right guard cover maintenance light, left guard cover maintenance light and screen maintenance light respectively, which is convenient for nearby operation and use; each button in the bus light control panel has an operation indicator light and a self-diagnosis function. There are three colors: green, yellow and red. The green light means that the switch is pressed and connected, and the CAN message is sent normally; the yellow light means that the switch message is sent to the controller to execute the control logic; the red light means that the switch button fails.

[0053] The traditional lighting wiring method is a parallel structure. One electrical appliance is equipped with a power cord and a switch. The switch is in the cab. When there are many electrical appliances, the number and length of power cords increase proportionally. CAN communication uses a serial bus to form a local area network in the system. It uses multi-master communication and each node can send information to the bus. This design sends control signals to the bus by multiple switches. The on-board control unit receives the signal and sends the data to the lighting driver unit (BCM) through the CAN bus. It can simplify the lighting system wiring, save wiring harnesses, facilitate detection and maintenance, and improve the level of electronicization and informatization of agricultural machinery.

[0054] The lighting driver unit (BCM) has multiple functions such as short circuit protection, overload protection, overvoltage protection and power reverse connection protection. The lighting driver unit (BCM) can send the fault diagnosis results of the lighting control output terminal to the on-board control unit through the CAN bus, and the on-board control unit will then send the fault information to the intelligent display terminal. Users will obtain the vehicle fault information at the first time, which is convenient for fault inspection and maintenance.

[0055] This system adopts SAEJ1939 protocol, defines the data packets transmitted on CAN bus as extended frame form, and develops its own high-level application protocol.

[0056] The reception of CAN messages is also automatically completed by the vehicle control system. The receiving information reads the receiving data from the vehicle control unit and then performs corresponding processing. The basic method is the same as the sending program, but the receiving program uses an interrupt mode. The receiving program is mainly for each sub-module to receive the command data of the control module, or the control module to receive the fault information of each sub-module. The CAN receiving flow chart is as follows Figure 4 shown.

[0057] like Figure 5 As shown in the figure, the light driving unit receives the message information from the vehicle control unit and controls the corresponding headlight according to the obtained control information (message information). At the same time, the level of the input, output and fault diagnosis pins of the headlight is collected when the headlight is working, and the fault analysis is performed. If a fault occurs, the fault information is sent to the vehicle control unit. After detecting the signal sent by the control module, the light driving unit first identifies it through the ID identifier of the message frame to see if it belongs to its own message information. If so, check whether this message is a query information. If so, return a response message to the vehicle control unit; if it is a control information, control the headlight of the corresponding ID, and measure the potential of the measurement point on the driving circuit of the headlight, and process it to see if it fails. If a fault occurs, send information to the on-board control unit via the CAN bus.
