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.
