Embodiment Construction
[0014] The present invention will be further described below in conjunction with the accompanying drawings.
[0015] A dual-machine hot backup electronic speed governor switching control method for dual-coil hot redundant actuators, the dual-machine hot backup electronic speed governor consists of a speed sensor 1, a speed sensor 2, a controller A, a controller B, CAN1 and CAN2 communication bus, dual coil proportional solenoid actuator, coil 1 drive and coil 2 drive. The controller A collects the speed through the speed sensor 1 and controls the driving coil 1, and the controller B collects the speed through the speed sensor 2 and controls the driving coil 2; the CAN1 and CAN2 realize the communication and data between the two machines Sharing; Coil 1 and Coil 2 can act independently to complete the control function.
[0016] The switching control of the dual-machine hot-backup electronic governor and the dual-coil hot-redundancy proportional solenoid actuator is realized in...

The invention relates to a switching control device for a double-coil hot-redundancy actuator of a duplicated hot-redundancy electronic speed regulator. According to the switching control method for the double-coil hot-redundancy actuator of the duplicated hot-redundancy electronic speed regulator, the duplicated hot-redundancy electronic speed regulator is included and comprises a rotation speed sensor 1, a rotation speed sensor 2, a controller A, a controller B, a CAN1 communication bus, a CAN2 communication bus, the double-coil proportion electromagnet actuator, a coil 1 drive and a coil 2 drive, the controller A collects the rotation speed through the rotation speed sensor 1 and controls a drive coil 1, and the controller B collects the rotation speed through the rotation speed sensor 2 and controls a drive coil 2; communication and data sharing between two machines are achieved through the CAN1 and the CAN2; and a control function is achieved through independent actions of the coil 1 and the coil 2. By means of the duplicated hot-redundancy electronic speed regulator, it is guaranteed that a diesel engine stably and continuously runs without shutdown under the situation that a single-machine system breaks down, and the reliability of the electronic speed regulator is improved.
Description
technical field [0001] The invention relates to a switching control method for dual-coil hot-redundant actuators of a double-machine hot-backup electronic governor. technical background [0002] The development of diesel engine has a history of hundreds of years, and it has been widely used because of its high thermal efficiency, wide power range, good adaptability and other advantages. The diesel engine governor is a very important part of the diesel engine. The reliability of the diesel engine electronic governor is an important part of the reliability of the diesel engine. The reliability is one of the important performance indicators for the design of the diesel engine electronic governor. There are usually two ways to improve the reliability of the control system. One is to avoid errors in the design process of the electronic governor. If necessary, some fault-tolerant links can be added to the stand-alone system to be tolerant to some common faults of the system. The ...
