5. The parking space management system of claim 4, wherein: the indicating unit comprises an LED indicating lamp, an LED driving circuit and a display;
the control input end of the LED driving circuit is connected with the parking lot server, the output end of the LED driving circuit is connected with the LED indicator lamp, and the input end of the display is connected with the parking lot server;
the LED indicator lamps are multiple and arranged at parking positions of a parking lot in an array mode.
6. The parking space management system of claim 4, wherein: the parking lot server determines whether the vehicle in the reservation information can be parked at the current idle position according to the following method:
determining the width dimension W of the idle position, the parking width safety distance Ws, the parking length safety distance Ls and the idle position length dimension S;
comparing the length dimension S of the idle position with the sum of the length dimension L1 of the target type vehicle and the parking length safety distance Ls, if S is larger than or equal to L1+ Ls, entering a step S32, otherwise, the current idle position does not accord with the target type vehicle;
predicting the number n of vehicles with the current type which can be parked in the width W of the current idle position, and judging
If the remainder is less than the set value, if so, the target type vehicle can be parked at the current idle position, wherein Wv is the maximum width of the target vehicle.
7. The parking space management system of claim 6, wherein: the system also judges whether the vehicle is parked at the reserved parking space, and if the vehicle is not parked at the reserved parking space, the parking lot server feeds back prompt information to the intelligent mobile terminal to inform the vehicle owner of parking according to the reserved parking space.
8. The parking space management system of claim 7, wherein: the system judges whether the vehicle is parked on the reserved parking space according to the following method:
the method comprises the steps that an RFID reader-writer closest to an appointed parking space in a parking lot collects electronic tag information of a target vehicle and transmits the electronic tag information to a parking lot server, wherein the electronic tag information comprises a vehicle type, a license plate number and electronic tag identification information;
the parking lot server judges whether the acquired license plate number and the acquired vehicle type are consistent with the license plate number and the vehicle type in the reservation information, if so, the power parameter information of the electronic tag of the current target vehicle is searched according to the electronic tag identification information, the distance between the reserved parking space and the RFID reader-writer is determined, and the theoretical attenuation value of a response signal sent by the electronic tag of the target vehicle reaching the RFID reader-writer is determined according to the power parameter information and the distance;
the RFID reader-writer receives a response signal of an electronic tag of a target vehicle, judges the actual power of the received response signal and transmits the actual power to the parking lot server, the parking lot server compares the difference value between the actual power and the theoretical attenuation value of the response signal with a set threshold range, if the difference value is in the set threshold range, the target vehicle is shown to be parked on the reserved parking space, otherwise, the target vehicle is not parked on the reserved parking space, and the target vehicle is prompted to park according to the reserved parking space.
9. The parking space management system of claim 4, wherein: the indicating unit is a laser projector, and the control input end of the laser projector is connected with the parking lot server.
