摘要

本设计是以DSP为主控制器设计的一线制汽车控制器的接收板检测装置，配以相应的外围接口电路，以实现对产品的质量检测。一线制汽车控制器接收板接收一线制汽车控制器发射板以主频3.3K发出的一系列2V或4V电平脉冲，然后控制相应的器件动作。所设计的接收检测板要自行模拟发射板发出主频3.3K的一系列2V的电平脉冲，在相应位置的2V电平脉冲变为4V电平脉冲，然后对接收板的输出信号进行检测，以判断接收板的好坏。
接收检测板主控制器采用TMS320F240，脉冲发射采用DAC8562实现，接收板信号采集使用TMS320F240芯片内的AD和外围电路CD4051。整个接收板设计硬件简单，软件采用c语言设计，编程灵活。

Examination of Receive board of one-line of motor controller

Abstract
The examination board of receive board of one-line of motor controller regard DSP as the main controller, going together with to interface circuit to examine receive board. Receive board of one-line of motor controller receives signal of main frequency an 3.3K a series for sending out 2V or 4V electricity regular pulses from send board of one-line motor controller. Then the control relay is closed. The design of the examination board of receives board is requested imitate by oneself the send board to send out the main frequency an 3.3K a series 2 V regular pulse. On the base of 2V regular pulse foundation top adds to 4V pulse, then the output signal of receive board is sampled to judge receive board.
The examination board of receives board of one-line of motor controller is adopts TMS320F240. The pulse output adopts the DAC8562. Receive board signal collecting use the TMS320LF240 of AD in the slice and CD4051. The hardware design of examination board of receives board is simple. Software design adopts the c language. Programming is easy.

Keywords: one-line of motor controller Receives board examination DSP
