TaskController

A microcomputer-based system for task control of animal experiments.The system is composed of three units: A, B, and C.Unit A is a bridge between the main unit (unit C), external power sources (+5V, +12V, or 240 VAC), and an recording device with an interface (e.g. Amplipex). Unit B is for regulation of buzzers, LEDs, and solenoid valves. Unit C is the central unit with four STM microcomputers.Unit A is composed of board A1, A2, and A3, which are for signal distribution, DC power and timing distribution, and 240 VAC regulation, respectively.Unit B is composed of board B, E, and F, which are for buzzers, LEDs, and solenoid valves, respectively.Unit C is composed of board C1 to C4 and one microcomputer on each, which are for control on buzzers and LEDs, solenoid valves, task cycles, and digitization of two analog external inputs, respectively.Schema and PCB design of each board and enclosure are given.Necessory componets are also given as a spreadsheet.Code examples for microcomputers are available in the GitHub page below.<br>

一款基于微型计算机的动物实验任务控制系统。该系统由A、B、C三个单元组成。
单元A作为主控单元（单元C）、外部电源（+5V、+12V或240V交流电）与带接口的记录设备（如Amplipex）之间的转接单元。
单元B用于管控蜂鸣器、发光二极管（Light Emitting Diode，LED）及电磁阀。
单元C为中央单元，搭载四颗STM微型计算机（STM microcomputer）。
单元A由A1、A2、A3三块电路板组成，分别用于信号分配、直流电源与时序分配，以及240V交流电调压。
单元B由B、E、F三块电路板组成，分别对应蜂鸣器、发光二极管及电磁阀的控制功能。
单元C由C1至C4四块电路板组成，每块电路板搭载一颗微型计算机，分别用于蜂鸣器与发光二极管控制、电磁阀控制、任务周期调控，以及两路外部模拟输入的数字化处理。
所有电路板及机箱的原理图与印刷电路板（Printed Circuit Board，PCB）设计文件均已提供，所需元器件清单亦以电子表格形式给出。
