【4】 In the operation process of the hot pepper direct sowing machine: the signal receiving and transmitting conversion controller 3 collects parameters such as the engine speed, the fuel oil rate, the engine oil pressure, the water temperature, the oil-water separation state, the air filter alarm state, the fuel oil level and the like through the CAN bus module 31; parameters such as heading angle, roll angle and pitch angle of a hot pepper direct seeding locomotive body output by the vehicle-mounted gyroscope are acquired in real time through the second data acquisition module 26; and calculating parameters such as the current speed, the steering state, the braking state, the driving state, the lifting state of the machine tool, the alarming state, the on-road state and the like of the pepper machine in real time. And then, the acquired data is packaged according to a fixed format, is sent to the remote controller 2 through the second 2.4G radio frequency transceiver module 28, is further forwarded to the display terminal 1 through the remote controller 2, and the display terminal 1 performs real-time processing and display on the received working condition data.

【5】 In the operation process of the hot pepper direct sowing machine: the display terminal 1 sends a 2.4G wireless link and Bluetooth monitoring data link on-off state data packet to the signal receiving and transmitting conversion controller 3 at regular time through the remote controller 2. The signal receiving and transmitting conversion controller 3 can respond the response data packet of the on-off state of the 2.4G wireless link and the Bluetooth monitoring data link to the display terminal 1 after receiving the data packet. If the signal receiving and transmitting conversion controller 3 does not receive the data packet of the on-off state of the 2.4G wireless link and the Bluetooth monitoring data link within the specified time, the current pepper direct sowing machine is considered to be in an uncontrolled state, and the pepper direct sowing machine is controlled to brake suddenly and drive the alarm horn to alarm. And if the display terminal 1 does not receive the response data packet of the on-off state of the 2.4G wireless link and the Bluetooth monitoring data link within the specified time, a wireless data link interruption alarm prompt frame is popped up to the remote control personnel.

According to the invention, through the arrangement of each module in the remote controller and the signal transceiving conversion controller, the long-distance stable and reliable control of the pepper direct sowing machine is realized at lower cost, so that farmers can realize large-scale pepper planting without entering the ground, and the urgent requirements of the farmers are met.
