The inverter compressor controller is the main command device, which controls the start, speed regulation, braking and reverse rotation of the motor by changing the wiring of the main circuit or the control circuit in a predetermined order and changing the resistance value of the circuit. It consists of a program counter, a command register, a command decoder, a timing generator and an operation controller. This is the "decision-making organ" that carries out the command and completes the work of coordinating and directing the entire computer system.

What is the classification of inverter compressor controller?

The controller combines the logic controller and the micro-program controller, each has its own advantages and disadvantages. Combinational logic controller design cumbersome, complex structure, after the completion of the design can not be modified or extended, but the speed is very fast. The microprogram controller is easy to design, simple in structure, easy to modify or expand, and the function of modifying the machine command only needs to re-compile the corresponding microprogram. To add a machine instruction, simply add a microprogram to the control memory, but this is achieved by executing the undetermined. (William Shakespeare, windows, machinery, machinery, machinery, machinery, machinery, machinery, machinery) The specific comparison is: combinational logic controller, also known as hard cable controller, is composed of logic circuits, which is a function that completely relies on hardware to execute commands.

Microcontroller (MicroController) is also known as MCU or C, also known as single-chip microcontroller, which integrates ROM, RAM, CPU, I/O into the same chip, microcontroller in recent years, the maturity of products, the number of investment enterprises, a wide range of applications. Large overseas factories develop fast and have a wide range of product lines, so the technology is high, and local manufacturers are product-oriented to win.

What is the basic configuration of the inverter compressor controller?

1. The command register is used to save the command being executed. The instruction is divided into two parts: the operation code and the address code. Opcodes are used to represent the operational characteristics of the command, such as plus, minus, etc. The address code provides information that forms the operand address or operand address of the instruction (in this case, the operand address is formed by the address forming circuit). There is a command called the transfer command that changes the normal order in which commands are executed. The address code portion of this command provides the address of the command to be executed.

2. Opcode decoder: Opcode used to decode the command and generate the appropriate control level to complete the function of analyzing the command.

3. Timing circuit: used to generate a time indication signal. On a microcomputer, the time stamp signals are typically: level command cycles, bus cycles, and clock cycles. The micro-operation commands generate various micro-operation commands to complete the tasks specified by the commands in the circuit. These commands are primarily generated based on the time stamp and the operational characteristics of the commands. This circuit is actually a circuit implementation of each micro-operation control signal expression (such as the AL expression above) and is a complex part of the combinational logic controller. 4. Command counter: is an address for forming a command to be executed next. Typically, the commands are executed sequentially and the commands are stored sequentially in memory. Thus, in general, the address of the next command to be executed can be formed by adding 1 to the current address, the micro-operation command "1" being used for this purpose. When a send command is issued, the address of the next command to be executed is the address to be sent. The address is sent directly to the command counter, in the address code field described earlier here.

The microprogram controller is proposed because of the inconvenience, inflexibility, modification and expansion of the combined logic design.
