**4. Conclusions**

A control system of an electrically driven precision maize seeder based on the CANopen protocol was designed and developed. A circuit board with motor drive and sowing performance detection was integrated. The matching model of vehicle speed and seeding plate speed was established through the PID control algorithm. Terminal monitoring software for real-time monitoring of sowing parameters was designed. According to the GB/T 6973-2005 standard, the evaluated parameters were the following: photoelectric sensor detection performance, fault alarm rate, qualified rate, reseeding rate, and missed rate. The following conclusions can be drawn:
