控制器是计算机的指挥中心,负责决定执行程序的顺序,给出执行指令时机器各部件需要的操作控制命令。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,若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。


电子控制器(ECU)是一个微缩了的计算机管理中心,它以信号(数据)采集、计算处理、分析判断、决定对策作为输入,然后以发出控制指令、指挥执行器工作作为输出有时,它还要给传感器提供稳定电源或是参考电压。其全部功能是通过各种硬件和软件的总和来完成的,其核心是以单片机为主体的微型计算机系统。借助于大规模集成电路,ECU已经可以把复杂而多样的几百个元器件全都做在1~2块多层电路板上,封装在一个书本那样大的盒子里,用铝制外壳屏蔽起来。如果再采用智能功能器件,则ECU的体积还可以缩小。


在电路组成方面,SYI-1型多用电子控制器主要由电源变压器、桥式整流电路、放大电路、可控硅触发电路、交流输出电路、电压反馈电路、电子继电器和温度接点等几部分组成;WMK-05型温度控制器主要由交流感温电桥、交流放大器和交流有源信号输出等四部分组成。



Temperature Controller Electronic Control Board

The controller is the command center of the computer, which is responsible for deciding the order of executing the program and giving the operation control commands needed by each part of the machine when executing the instructions. It is composed of program counter, instruction register, instruction decoder, sequence generator and operation controller. It is the "decision-making body" for issuing commands, that is, to coordinate and direct the operation of the whole computer system. Controllers are grouped into logic controllers and microprogrammed controllers, each of which has its advantages and disadvantages. The design of combinational logic controller is troublesome and its structure is complex. Once the design is completed, it can not be modified or expanded, but its speed is fast. The design of microprogrammable controller is convenient, its structure is simple, and it is convenient to modify or expand. To modify the function of a machine instruction, only need to rewrite the corresponding microprogram. To add a machine instruction, only need to add a microprogram in the control memory. Sequence, however, is performed by performing a micropath.

Electronic Controller (ECU) is a miniature computer management center. It takes signal (data) acquisition, calculation, processing, analysis, judgment and decision as input, and then sends out control instructions and commands the work of actuators as output. Sometimes, it also provides stable power supply or reference voltage for sensors. Its whole function is accomplished by summing up all kinds of hardware and software. Its core is a microcomputer system with single chip as the main body. With the help of large-scale integrated circuits, ECU has been able to make hundreds of complex and diverse components on 1-2 multi-layer circuit boards, encapsulated in a book-sized box, and shielded with an aluminium shell. If intelligent functional devices are used again, the volume of ECU can be reduced.

In terms of circuit composition, SYI-1 multi-purpose electronic controller mainly consists of power transformer, bridge rectifier circuit, amplifier circuit, thyristor trigger circuit, AC output circuit, voltage feedback circuit, electronic relay and temperature contact, etc. WMK-05 temperature controller mainly consists of AC induction temperature bridge, AC amplifier and AC active signal output.
