Digital speed governor
Digital governor is a kind of microcomputer control equipment which is simple and easy to operate. The communication network composed of various sensors and governors is directly constituted. Various control units used in automatic control systems. Widely used in CNC machine tools, motor, automobile and other industries. It is characterized by analog output, that is, digital governor form. A device used to adjust the speed of a motor, called a governor. It is used to control the speed of the mechanical moving parts in the process of movement. When the motion accuracy changes, the internal mechanism of the equipment also changes (the direction of motion or speed) to change the mechanical properties to achieve the required speed, so as to achieve the driving effect. In various movements, it is necessary to adjust the speed of the mechanical transmission structure or change the transmission ratio to achieve the purpose of control. In modern industry widely used in industrial and civil aspects of all kinds of motor is mainly used to control motor equipment: such as a variety of control cabinets, all kinds of motor and other electrical equipment such as motor, electric tools, all kinds of automatic control equipment, textile machinery equipment and so on.
First, the main composition of the governor
1. The frame is equipped with a number of shafts, whose function is to drive the motor rotation. 2. Planetary gear: The governor changes the speed of the motor by rotating the planetary gear, so that it changes the transmission ratio in the process of movement, to achieve the purpose of driving. 3. The reducer is composed of different forms of gears and different materials. 4. Motor: The device that provides electric power to the motor. 6. Drive shaft: can change the speed of the governor. 7. Gear and reducer: the gear on the rotor can make it do high-speed rotation.

Two, transmission ratio selection
When using gear transmission, it is necessary to pay attention to that there is a certain gap between the moving parts, such as the transmission ratio of 0.001, the motor working transmission ratio of 0.001×0.001=0.001, then each transmission part of the motor working in a transmission ratio of 0.001×0.001=0.001 speed range. If a transmission component does not work within a transmission ratio of 0.001×0.010=0.001 (without considering other factors), the structural component can only get relative motion but not relative motion. As shown in the figure, a mechanical transmission system is controlled by changing the working speed of the motor. The principle is as follows: When the speed of the motor is constant, the moment of inertia of the rotating part is transferred to the iron core on the junction post through the motor rotor. When the motor rotor rotates, the iron core on the core does not rotate. When the rotor rotates to a fixed position, the clearance at the end of the iron core decreases through the meshing clearance between the shaft and the rotor, causing the axial movement of the iron core, which changes the original structure. There are two driving modes of the motor: the reverse speed is directly generated by the shaft of the motor. At this time, if the motor rotor does not rotate or the transmission change caused by the rotor rotation is very small, can only be adjusted by the reverse; Otherwise, big changes may occur.
Iii. System requirements
As the application object of PLC is the production control center, so the system needs to have good scalability. At the same time, considering the communication and data transmission with other equipment, in order to realize the communication with PLC, the PLC communication interface must be designed. In order to realize data transmission, it is necessary to provide a high-speed serial communication interface, so as to avoid data loss caused by serial communication. Second need to have a clock function. At the same time, the clock function can make it work in low power consumption state. Finally, because it adopts embedded digital programming logic module, it can reduce the time of software development. In addition, PLC has a good set of data sending and receiving functions. In order to meet the requirements of system control, the PLC must be designed and have a strong data processing function and programming ability. In addition, it should have the ability to communicate with other equipment and sensor equipment and send data.
