With the increasing logging technology, the large amount of information and large combinations of downhole instruments put forward an increasingly urgent demand for the real-time control of high-speed cable transmission systems and instruments. In this regard, the rapid development of computer technology provides the ground equipment Strong support. The computer technology used in the downhole equipment to complete a variety of acquisition, control and data transmission, so that together with the ground computer intelligent cable telemetry system, and on this basis, the development of high reliability logging tools and imaging logging system has become The Trend of Logging Technology Today. Computer technology used in logging tools, foreign companies and domestic counterparts have developed. Existing logging systems must keep a breakthrough in technology leadership, market expansion, brand creation and industrialization. The main problems facing the original downhole equipment development so far and in the future are: (L) Early development of complex circuits, discrete components and more, resulting in high cost, reliability and maintainability poor. (2) The length of the single-instrument line is long, and the combined length is too long, which greatly increases the technical difficulty and risk of large-scale detection of horizontal wells. At present, the demand for horizontal well detection is increasing. (3) After the combination, the distribution of the cores becomes more and more tight. Even if they are barely enough, the mutual influence, crosstalk, signal attenuation and distortion often appear. As the combination and precision requirements increase, the core will become increasingly prominent. (4) The external interfaces of various instruments are not uniform, which brings difficulties to any combination of instruments, and also makes it difficult to standardize the control of the collection and control of instruments on the ground and affects the reliability of the whole system. (5) delay caused by a large combination of issues, the underground data acquisition, control and transmission of real-time affected. Some of the above problems can be solved within a small area and some problems can be solved temporarily. However, it is difficult to fundamentally eliminate the negative impact on the current system and especially the future development of the system. In particular, it is very difficult to achieve real miniaturization and high reliable. From the system and the overall perspective of the instrument to transform the system is the fundamental way to solve the problem. Single-chip microcomputer with highly integrated logic control function can not only solve the above problems, but also meet the trend of future development, making the instrument more concise and more uniform. Electronic Automatic Speed Controller
The speed regulator is a professional design of the regulating board, which includes all aspects of self leveling. It is mainly used to automatically adjust the controlled parameters of the system composed of pressure, tension, speed, temperature and other parameters.
All important current can be controlled by a single external resistor. The simple motor start and stop can be set. The starting timing sequence can be completed by two capacitors by using the power supply of the circuit. The peripheral circuit simply adopts the new reverse potential commutation technology, It can provide the minimum torque without jitter, and control the maximum efficiency. It has reversing PLC, which can effectively suppress the PWM peak noise signal
