摘要

Most of the OBU (On Board Unit) devices of vehicles use MCU to control the infrared transmission and reception for the infrared-oriented parking systems. However, the more battery power of the OBU device will be dissipated. In this paper, a non-processor OBU device is proposed to reduce its standby power consumption. Besides, when the OBU device receives an infrared induced signal to cause transmitting an infrared identification signal, the data collision also can be avoided by the design of the delay control circuit to further increase the stability of identification.
