In a preferred embodiment of the present invention, based on the above problems in the prior art, there is provided a fully wireless parking space guidance system, as shown in fig. 1, including:
the system comprises at least one control area which is divided in advance, wherein at least one node control module 1, a plurality of parking space detection modules 2, at least one empty vehicle guide module 4 and a plurality of garage illumination modules 3 are arranged in each control area;

The parking space detection module 2 adopts a parking space detector, the parking space detector is arranged above a lane in front of a parking space, and the mounting height is 2-3.5 meters. The node control module 11 employs a node controller.
As a preferred embodiment, the technical solution is further described by taking an example that six parking space detection modules 2 are arranged in the control area, and the parking space detection modules 2 perform wireless networking with the node control module 1 by using a first channel. The node control module 1 is a node controller X, and the six parking space detection modules 2 are respectively a parking space detector a, a parking space detector B, a parking space detector C, a parking space detector D, a parking space detector E and a parking space detector F. The parking space detector A, the parking space detector B and the parking space detector C are in the communication range of the node controller X, and the node controller X sends state query instructions to the parking space detector A, the parking space detector B and the parking space detector C respectively. And meanwhile, the parking space detector A, the parking space detector B and the parking space detector C respectively acquire corresponding delay forwarding time according to the signal intensity grade associated with the received state query instruction. The signal intensity level is in positive correlation with the delayed forwarding time, wherein the signal intensity level of the state query instruction received by the parking space detector C is lower, so that the delayed forwarding time of the parking space detector C is shorter, and the parking space detector C forwards the state query instruction first. And after the parking space detector B and the parking space detector A receive the state query instruction forwarded by the parking space detector C, the forwarding of the state query instruction is not carried out.

The intelligent garage illuminating lamp D1, the intelligent garage illuminating lamp D2 and the intelligent garage illuminating lamp D3 are in the communication range of the node controller X. Because the intelligent garage lighting lamp D1 in the node controller X communication range receives the weakest signal intensity who obtains the parking stall state of taking the biography, consequently the time that the intelligent garage lighting lamp D1 took the biography is the shortest, and intelligent garage lighting lamp D3 and intelligent garage lighting lamp D2 no longer take the place of the parking stall state to pass after receiving the parking stall state that intelligent garage lighting lamp D1 took the biography. And then intelligent garage light D1 passes to intelligent garage light D4 and the intelligent garage light D5 of intelligent garage light D1 communication range with the parking stall state area. The intelligent garage illuminating lamp D4 receives the weakest signal strength of the parking space state which is transmitted, so that the time for the intelligent garage illuminating lamp D4 to transmit is shortest, and the intelligent garage illuminating lamp D5 does not transmit the parking space state after receiving the parking space state which is transmitted by the intelligent garage illuminating lamp D4. And finally, the intelligent garage illuminating lamp D4 transmits the collected parking space state to the parking space guide screen A1, and the parking space guide screen A1 receives the parking space state of the control area and displays the number of empty parking spaces and the area information related to the control area. And the parking space guide screen A1 carries out belt transmission on the parking space states of the control area and the adjacent control area according to the received parking space state of the control area, and finally, the full wireless communication of the parking space guide system is realized.
In this embodiment, when the garage does not have personnel or vehicle and removes, intelligent garage light power is 15% of full power, and when the radar of intelligent garage light through self sensed personnel or vehicle and removed, the intelligent garage light was with power up-regulation to full power state, sent the garage light on the other side through wireless mode simultaneously and sent the instruction of turning on the light to garage light on every side, and the garage intelligent light that notifies around gets into full power state. After the vehicle leaves for 20s, the power of the intelligent garage illuminating lamp is reduced to 15% of the full power when no other person or vehicle moves. The intelligent garage illuminating lamp senses the movement of a vehicle, the intelligent garage illuminating lamp increases the power to a full power state and sends a 2-hop lamp-on instruction at the same time, after the intelligent garage illuminating lamp and the intelligent garage illuminating lamp receive the lamp-on instruction of the intelligent garage illuminating lamp, the power of the intelligent garage illuminating lamp and the power of the intelligent garage illuminating lamp are adjusted to the full power state, the intelligent garage illuminating lamp is provided with the lamp-on instruction, and the hop number of the lamp-on instruction is reduced by 1; the intelligent garage illuminating lamp and the intelligent garage illuminating lamp receive the turn-on instruction that intelligent garage illuminating lamp and intelligent garage illuminating lamp were worn, with power adjustment to the high power state, nevertheless because turn-on instruction jump number falls to 1, the event no longer takes the biography instruction, so intelligent garage illuminating lamp and intelligent garage illuminating lamp keep former power state unchangeable.
