Verification device for timing and charging of parking lot

A verification device for timing and charging of a parking lot relates to a timing and charging device of the parking lot, which consists of a standard time service device, a synchronized triggering device and a master control device. The standard time service device and the synchronized triggering device are respectively connected with two ends of the master control device. The verification device for timing and charging of the parking lot performs on-line verification on accuracy of time interval and in-out moment of the timing and charging device of the parking lot in onsite running so as to guarantee synchronism of triggering and ensure verification results to be reliable and accurate, low in uncertainty, high in accuracy and verification efficiency and capable of storing verification data.
