The 972355188 Application Field and its Working Principle

The 972355188, also known as the fixed-frequency variable-length pulse word controller, is a compact, low-power, completely integrated, multichannel, pulse-width modulation digital controller. It is mainly suitable for the control of small or medium-sized water and electricity, mechanical and chemical processes, the air-conditioning and heating industry and the management of the rotary table and the speed of the frequency motor. It also has a wide range of applications, such as fan speed control, power converters, motor control, intelligent instruments, etc. In addition, this controller can be configured as a complete set of single-chip microcomputer system, which can provide control, regulation and communication between the host computer and peripheral equipment.

The 972355188 consists of a microcontroller, memory, A/D and D/A converters, a communications port and other components. The core is an 8-bit microcontroller that can contain up to 8KB of instructions. Its EEPROM or flash memory can store the control program and the parameters of the control program. The A/D converter can monitor and acquire various analog signals; the D/A converter can provide current and voltage output signals. It also has a serial communications interface that can communicate with the host computer and send control signals to drive relays, triacs, solid-state relays, and other output devices.

The basic working principle of 972355188 is to output a control action according to the preset program instructions by controlling the opening and closing of the output relay or the firing angle of the thyristor. The output control action is determined by the detected feedback signal, such as temperature, pressure, flow, current, voltage, etc. The feedback signal is compared with the set value to obtain the deviation, and then the corresponding output action is determined according to the preset PID parameters, and the parameters can be adjusted to optimize the control performance.

The 972355188 is capable of controlling multiple loops at the same time. It not only has the common PID control mode, but also can realize the multi-loop structure with cascade, program control multiple cascade, selectable cascade and multi-stage PID. In addition, it also has fuzzy logic control, Bumpless transfer, stepl response and a serial port for downloading of programs to and exchanging data with a host computer.

In summary, the 972355188 is a multi-functional, low-power, fully integrated controller that can provide reliable process control, temperature control, motor speed control, and measurement control for a variety of applications. Its advantages are: high control accuracy, rich control mode, wide input range, multiple PID cascade, monitoring and fuzzy logic control, real-time communication, strong self-diagnosis and alarm functions, flexible program structure and good anti-interference ability.
