The main role of encoder An encoder is a device that compiles or converts a signal (such as a bit stream) or data into a signal that can be used for communication, transmission, and storage. The encoder converts the angular displacement or linear displacement into electrical signals. The former is called the encoder and the latter is called the encoder. According to the readout method, the encoder can be classified into contact type and non-contact type; according to the working principle, the encoder can be divided into two types: incremental type and absolute type. Incremental encoders convert the displacement into a periodic electrical signal, then convert this electrical signal into a counting pulse, and use the number of pulses to indicate the magnitude of the displacement. Each position of the absolute encoder corresponds to a definite digital code, so its indication is only related to the starting and ending positions of the measurement, and has nothing to do with the middle process of the measurement. It is a rotary sensor that converts rotational displacement into a series of digital pulse signals that can be used to control angular displacement. If the encoder is combined with a gear bar or screw, it can also be used to measure linear displacement. After the encoder generates the electrical signal, it is processed by the CNC, the programmable logic controller PLC, and the control system.

Pump decoupling solution problem analysis and incremental reform 1, Preface My workshop decarburization system uses hot potash method to remove CO2 in low volatility to provide qualified hydrogen-nitrogen mixture for ammonia synthesis and at the same time provides CO2 gas with purity greater than 98% for urea production. The solution circulation is mainly provided by a solution pump (decarburization pump). The pump from the seventies imported from Japan, the technical parameters in Table 1. The pump performance is good, simple operation, stable operation. Especially MVB2830B type supporting motor, stable operation, the use of over 20 years has never been overhauled. Over the years, due to the low system load, the normal process flow required for less than 200m3 / h, much less than the pump design capacity of 480m3 / h. In order to reduce power consumption, in 92 years its impeller cylindrical cutting, to achieve the use effect. However, since the first phase of fertilizer "8.13" was put into operation in 1999, the required process flow increased to 240 m3 / h. According to the reconstruction group accounting, and the impeller to restore the original large impeller, basically meet the production requirements at the time. In 2001, the second phase of fertilizer "8.13" was put into operation, and the required process flow increased to 280m3 / h. At this time, the problem was prominently exposed, the flow of large pump could no longer be increased, liquid flow phenomenon occurred in atmospheric tower, oper

Angle encoder Angle encoders are specially designed to describe encoders with accuracy higher than ±5" and with more than 10000 lines. These devices can be used on CNC rotary tables, machine rotors, indexing devices, high-precision angle measuring tables, angles Weights and measures, antenna and telescope precision equipment. Rotary encoder HEIDENHAIN rotary encoders can be used as rotary motion, angular velocity measuring sensors, or in conjunction with mechanical measuring standards, such as screws, for measuring linear motion. Applications include motors, machine tools, woodworking machinery, textile machinery, robotics and transportation equipment as well as various measuring, testing and inspection equipment. Incremental angle encoders and rotary encoders determine the current position by counting the number of counting signals from the starting point number or the subdivision circuit. HEIDENHAIN's incremental Guanshan holds the reference point. When it is turned on, the reference point zeroing operation must be performed to establish the origin. Rotary encoders with commutation signals provide the angular position of the shaft without the need to move before the measurement. The accuracy is sufficient to correctly control the phase of the rotating magnetic field of the permanent magnet three-phase motor. Absolute angle encoders and rotary encoders can directly provide the current position value wit

Encoder introduction An encoder is a device that compiles and converts a signal (such as a bit stream) or data into a form that can be used for communication, transmission, and storage. The encoder converts the angular displacement or the linear displacement into an electrical signal. The former is called a code wheel, and the latter is called a code wheel. According to the readout mode, the encoder can be divided into two types: contact type and non-contact type. Contact type uses brush output. A brush contacts the conductive or insulating region to indicate whether the state of the code is "1" or "0"; the non-contact receiving sensitive component is a photosensitive component or a magnetic sensing component, and the light transmitting region is opaque when the photosensitive component is used The light zone indicates whether the state of the code is "1" or "0". The binary signal of "1" and "0" is used to convert the collected physical signal into machine code readable electrical signal for communication, transmission and store.

Encoding, classification and application of the encoder An encoder is a device that compiles and converts a signal (such as a bit stream) or data into a form that can be used for communication, transmission, and storage. The encoder converts an angular displacement or a linear displacement into an electrical signal, the former being called a code wheel and the latter being called a code ruler. According to the readout mode, the encoder can be divided into contact type and non-contact type; according to the working principle, the encoder can be divided into two types: incremental type and absolute type. The incremental encoder converts the displacement into a periodic electrical signal, which is then converted into a counting pulse, and the number of pulses is used to represent the magnitude of the displacement. Each position of the absolute encoder corresponds to a certain digital code, so its indication is only related to the start and end positions of the measurement, regardless of the intermediate process of the measurement. First, the classification of the encoder According to the detection principle, the encoder can be divided into optical, magnetic, inductive and capacitive.

According to the working principle, the encoder can be divided into two types: incremental (SPC) and absolute (APC). The incremental encoder converts the displacement into a periodic electrical signal, which is then converted into a counting pulse, and the number of pulses is used to represent the magnitude of the displacement. Here is some introduction to incremental encoders. 1. working principle The working principle of the photoelectric incremental encoder is as follows: the pulse code disc rotating together with the rotating shaft has a uniformly engraved grating, and a plurality of transparent sections and shading sections are evenly distributed on the code disc. Incremental encoders do not have a fixed starting zero. The output is a pulse proportional to the increment of the corner. A counter is required to count the number of pulses. Each time a light transmissive area is rotated, a pulse signal is sent, the current value of the counter is incremented by 1, and the count result correspon

To improve its accuracy, it is necessary to increase the design of the encoder. Difficulty and increase the output of parallel signals, which is not conducive to the long-distance communication between the servo unit and the encoder. The absolute encoder is used, except that its accuracy is several times higher than that of the incremental encoder. High-speed serial communication saves communication lines for long-distance communication. At the other end of the encoder, CPLD and absolute encoder are used for high-speed serial communication. The CPLD then converts the received encoder information into parallel data transmission. The DSP in the servo unit performs arithmetic control. This paper will give the software and hardware design of high-speed serial communication between CPLD and absolute encoder . hardware design The hardware is mainly composed of three modules: power supply, CPLD and its peripheral circuits and absolute encoder interface circuit.
