Early automatic control system relies on the relay Contactor to achieve, and its features are: simple structure, low cost, antiinterference capability, can achieve centralized control and remote control, but the introduction of fixed wiring, versatile and flexible of the poor and by the switch contacts, the low frequency contacts easily damaged, poor reliability. The design is based on the storage of vehicles PLC management systems, LED used two vehicles in the garage to show that the actual number. The use of two light sensor to monitor vehicle access and plete count, the two vehicles entered the house through the sensor and a digital display, two vehicles going through the sensor by a digital display, but only after a sensor vehicles will not count. In order to prevent accidents counting error, the system used repeatedly checking procedures to enhance the reliability of the system. First of all, pay attention to control the distance between the two sensors, access to the garage with the certification procedures for the vehicles, through the sensor when people do not count。 Secondly, the introduction of the logical interlocked, and counting would start by counting lock, a Canadian Counting will have to lock pulse by pulse count, so in order to ensure reliability。 Finally, a reduction of the processing time to avoid vehicles in the vicinity of sensors for counting from the wrong campaign.
