Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

Fig. 1 illustrates a multi-tiered fence of an embodiment of the present invention. Referring to fig. 1, multiple levels of fences are arranged around the destination 11, and different levels of fences are arranged in a mutually inclusive relationship.

In the process of traffic flow control, the traffic flow control is performed according to the multi-layer fence as shown in fig. 1. Specifically, a plurality of layers of electronic fences are built, a vehicle cache is built, and the vehicle can continue to drive to the next electronic fence area after entering the electronic fence and waiting for an instruction.

The advantage of doing so is that each layer of rail can be targeted traffic control, reaches multi-level filtration final treatment result optimization.

Fig. 2 shows a flow of a method for accurately controlling a traffic flow according to an embodiment of the present invention. Referring to fig. 2, the traffic flow control method includes:

s21, constructing a multi-tiered fence around the destination.

And S22, acquiring an entering indication signal of the vehicle entering the outer fence.

S23, instructing the vehicle to wait at the outer fence.

In an exemplary embodiment, the above-described operation of instructing the vehicle to wait includes: sending and so on an indication signal to the vehicle at the outer fence; and storing the vehicle identification in a waiting cache.

And S24, sending a release signal to the vehicle according to the control logic, and allowing the vehicle to drive to the next layer of fence.

In an exemplary embodiment, the releasing operation includes: after the vehicle waits for confirmation, sending a release signal to the vehicle; the vehicle identification is cleared from the waiting buffer.

In this embodiment, after the vehicle enters a fence, it needs to wait for the confirmation message sent by the server. Each vehicle will only be released if it waits for the confirmation message.

Meaning that the vehicle is still in the fence and does not leave to give up transaction; and when the vehicle can not reach the next fence after time out, canceling the vehicle continuous traveling qualification.

In another exemplary embodiment, the releasing operation includes: when the vehicle needs to be released according to the waiting sequence, a releasing signal is sent to the vehicle; the vehicle identification is cleared from the waiting buffer.

In this embodiment, vehicles are stored in a waiting queue after entering a fence. Only if a vehicle needs to be released according to the queue order, the vehicle will be released.

S25, the operation from acquiring the entry instruction signal to transmitting the release signal is repeatedly performed until the vehicle reaches the destination.

It will be appreciated that after the release signal is sent, the original next fence becomes the outer fence for the new round of action. This is repeated until the vehicle reaches the final destination.

It is emphasized that in the implementation of the above method, all the fences are virtual electronic fences.
