A high speed coding system utilizes first and second coders. Specified input bits supplied from a sample and hold circuit are first coded by the first coder during a first coding stage and are in turn coded again by the second coder during a second coding stage.
The working method of high speed coding system
The working principle of high speed coding machine
The advantages of high speed coding machine
A high speed and low power encoder and its encoding method are provided. The encoder comprises a switching unit, which is used to receive the thermal code with a predetermined number of bits received in sequence, and outputs one bit of the received bit as the most effective bit, and outputs the other bits in parallel. And an encoder is used to switch from described unit receives the various bits is divided into multiple groups have a reservation number of bits, multiple bits encoded as scheduled in each group, the number of bits used is not used by each group to select the coding bits of a group, and output the least significant bit and described from the most significant bit of switching unit.
The coding results of the first coder govern the generation of the initial reference voltage of the first bit for coding in the second coder in order to provide an assumption that the necessary number of bits of the first coder are already coded by the second coder. There is an overlapping coding range of the first and second coders, and the system assures that coding errors in the first coder may be corrected within the overlapping coding range through coding of the coding bits of the first coder within the overlapping coding range of the second coder.
Will change to instantaneous mechanical shaft Angle with digital display, and gives the position loop comparator digital coding of binary digital system, the sensor is light code disc mechanical encoder Is cosine rotary transformer as well as the round inductosyn etc Device, which has simple structure, no contact with waterproof and dustproof corrosion resistance to shock vibration work stable and reliable Long service life and other advantages. Besides, Small size, precision, its resolution can be very high, no contact no wear; The same variety can detect both angular displacement and linear displacement with the help of a mechanical conversion device. The multi-turn photoelectric absolute encoder can detect the linear displacement of quite long range (such as 25-bit multi-turn). It has the advantages of long service life, easy installation, rich interface forms and reasonable price. The mature technology has been widely used at home and abroad many years ago. Multi -function, in addition to positioning, but also can far transmit the position at that time, conversion speed, on the frequency converter, stepper motor and other use is particularly important.
