Brake redundancy control system

The invention relates to a brake redundancy control system. The system comprises an industrial control device, an electro-hydraulic hybrid braking device and an electronic braking execution device, the electronic brake execution device comprises a motor and a brake, the motor is respectively connected with the industrial control device and the brake; the brake is also connected with the industrial control device; when the industrial control device detects whether the electro-hydraulic hybrid braking device fails or not, the industrial control device can further detect whether the motor fails or not, and when the electro-hydraulic hybrid braking device and the motor fail, the industrial control device generates a braking signal to control the brake to conduct braking, so that the braking accuracy is improved, and the mistaken braking problem is avoided. 本发明涉及一种制动冗余控制系统。该系统包括：工控装置、电液混合制动装置和电子制动执行装置；其中，电子制动执行装置包括：电机和制动器；电机分别与工控装置和制动器连接，制动器也与工控装置连接；当工控装置检测到电液混合制动装置是否失效时，工控装置会进一步检测电机是否失效，当电液混合制动装置和电机均失效时，工控装置生成制动信
