控制器（英文名称：controller）是指按照预定顺序改变主电路或控制电路的接线和改变电路中电阻值来控制电动机的启动、调速、制动和反向的主令装置。由程序计数器、指令寄存器、指令译码器、时序产生器和操作控制器组成，它是发布命令的“决策机构”，即完成协调和指挥整个计算机系统的操作

控制器控制器分组合逻辑控制器和微程序控制器，两种控制器各有长处和短处。组合逻辑控制器设计麻烦，结构复杂，一旦设计完成，就不能再修改或扩充，但它的速度快。微程序控制器设计方便，结构简单，修改或扩充都方便，修改一条机器指令的功能，只需重编所对应的微程序；要增加一条机器指令，只需在控制存储器中增加一段微程序，但是，它是通过执行一段微程。具体对比如下：组合逻辑控制器又称硬布线控制器，由逻辑电路构成，完全靠硬件来实现指令的功能。

电磁吸盘控制器：交流电压380V经变压器降压后，经过整流器整流变成110V直流后经控制装置进入吸盘此时吸盘被充磁，退磁时通入反向电压线路，控制器达到退磁功能。

门禁控制器：门禁控制器工作在两种模式之下。一种是巡检模式，另一种是识别模式。在巡检模式下，控制器不断向读卡器发送查询代码，并接收读卡器的回复命令。这种模式会一直保持下去，直至读卡器感应到卡片。当读卡器感应到卡片后，读卡器对控制器的巡检命令产生不同的回复，在这个回复命令中，读卡器将读到的感应卡内码数据传送到门禁控制器，使门禁控制器进入到识别模式。在门禁控制器的识别模式下，门禁控制器分析感应卡内码，同设备内存储的卡片数据进行比对，并实施后续动作。门禁控制器完成接收数据的动作后，会发送命令回复读卡器，使读卡器恢复状态，同时，门禁控制器重新回到巡检模式。

controller (English name: controller) refers to the master device that changes the wiring of the main circuit or control circuit and changes the resistance value in the circuit to control the start, speed regulation, braking and reverse of the motor in accordance with the predetermined order. Composed of program counter, instruction register, instruction decoder, timing generator and operation controller, it is a "decision mechanism" that issues commands, that is, to complete the coordination and command of the operation of the entire computer system

Controller The controller is divided into combinational logic controller and microprogram controller, and the two controllers have their strengths and weaknesses. Combinatorial logic controller design is troublesome, complex structure, once the design is completed, it can not be modified or expanded, but its speed is fast. Microprogram controller is convenient in design, simple in structure, easy to modify or expand, modify the function of a machine instruction, only need to reprogram the corresponding microprogram; To add a machine instruction, one simply adds a microprogram to the control memory, but it does so by executing a microprogram. The specific comparison is as follows: The combined logic controller, also known as the hard-wired controller, is composed of logic circuits and completely relies on hardware to achieve the function of instructions.

Electromagnetic sucker controller: The AC voltage 380V is reduced by the transformer, rectified by the rectifier to 110V DC, and then entered into the sucker by the control device. At this time, the sucker is magnetized, and the reverse voltage line is entered during demagnetization, and the controller achieves the demagnetization function.

Access controller: The access controller works in two modes. One is the inspection mode, and the other is the recognition mode. In the inspection mode, the controller continuously sends the query code to the card reader and receives the reply command from the card reader. This pattern continues until the card reader senses the card. When the card reader senses the card, the card reader generates a different reply to the inspection command of the controller. In this reply command, the card reader transmits the code data of the sensor card to the access controller, so that the access controller enters the recognition mode. In the recognition mode of the access controller, the access controller analyzes the code in the sensor card, compares it with the card data stored in the device, and implements subsequent actions. After receiving data, the access controller sends a command to the card reader to restore the status of the card reader. At the same time, the access controller returns to inspection mode.
