A kind of running vehicle tolling deviceTechnical field
The present invention relates to urban static traffic road parking management technology, relate in particular to a kind of running vehicle tolling device.
Background technology
Existing road parking way of paying have following four kinds: 1. the keeper directly collects cash as Parking Fee to the parking people; 2. the people of stopping drops into coin in the Parking Meter in roadside and buys down time; 3. on the Parking Meter single swipe the card (branch contact and contactless) buy down time; 4. on the Parking Meter, swipe the card for twice, during parking brush for the first time record stop the start time, when leaving brush for the second time, the Parking Meter is according to down time and expenses standard taking off corresponding cost from card.
In order to save human cost, Car park payment generally can use the Parking Meter to carry out automatic charging, can make whole charging process efficient, convenient for the charging of communication between car-mounted terminal and the Parking Meter.The Parking Meter for the parking stall on vehicle carry out radio communication, can send the wireless signal of certain power, because the position between the parking stall is close mutually, can there be interference in the signal between the Parking Meter, and the vehicle that occurs current parking stall even is by the phenomenon of the Parking Meter on adjacent parking stall charging.
Obviously, prior art need to be improved and enhanced.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, provide a kind of can effective jamproof running vehicle tolling device.
For achieving the above object, the present invention has adopted following technical scheme:
A kind of running vehicle tolling device comprises the Parking Meter by wireless mode and terminal communication, and described Parking Meter comprises the power adjustments unit, is used to regulate the radio communication power coverage of described Parking Meter in preset range.
Wherein said preset range is the coverage on parking stall, place, described Parking Meter.
Above-mentioned running vehicle tolling device, comprise Car park payment Parking Meter group, described Car park payment Parking Meter group comprises at least two described Parking Meters, and described Parking Meter group also comprises the first anti-tampering module, is used to prevent that Parking Meter and communication between terminals in the Parking Meter group from interfering with each other on time or frequency.
The wherein said first anti-tampering module is used to distribute different frequency to communicate to Parking Meter in the Parking Meter group and terminal.
The wherein said first anti-tampering module is used to distribute the different time to communicate to Parking Meter in the Parking Meter group and terminal.
Wherein said Car park payment Parking Meter group comprises main Parking Meter, and the described first anti-tampering module is arranged in the described main Parking Meter.
Above-mentioned running vehicle tolling device comprises at least two the described Car park payment Parking Meter groups and the second anti-tampering module, is used to prevent that the Parking Meter of each Parking Meter group and communication between terminals from interfering with each other on frequency.
The wherein said second anti-tampering module is used to distribute different frequency to give each Parking Meter group, and frequency and terminal that the Parking Meter in the Parking Meter group is distributed according to Parking Meter, place group communicate.
Wherein said Parking Meter also comprises delay unit, is used for the communication of terminal is produced random delay.
Owing to adopted above technical scheme, the beneficial effect that the present invention is possessed is:
(1) the present invention makes the power coverage of Parking Meter only limit to current parking stall, makes to avoid interference between the Parking Meter on the adjacent parking stall, has improved stability, the reliability of Parking Meter work;
(2) the present invention adopts frequency division or the mode of time-division to work by the Parking Meter group, avoids producing between same group the Parking Meter and disturbs, and has further improved reliability;
(3) the present invention works by adopting the mode of frequency division between the different Parking Meters group, effectively avoids the not interference between the Parking Meter on the same group.
Description of drawings
Fig. 1 is the structural representation of the embodiment of Car park payment Parking Meter according to the present invention;
Fig. 2 is the structural representation of another embodiment of Car park payment Parking Meter according to the present invention.
Embodiment
In conjunction with the accompanying drawings the present invention is described in further detail below by embodiment.
Fig. 1 illustrates the structural representation of the embodiment of Car park payment Parking Meter according to the present invention, comprises the Parking Meter by wireless mode and terminal communication, and this Parking Meter comprises the power adjustments unit, is used to regulate the radio communication power coverage of Parking Meter in preset range.
In the present embodiment, this preset range is the coverage on parking stall, place, described Parking Meter, and for example in 10 meters, this can adjust according to the size on parking stall.
In the present embodiment, the Parking Meter also comprises delay unit, is used for the communication of terminal is produced random delay.Can avoid replying simultaneously between Parking Meter and the terminal situation about always interfering with each other like this.
Fig. 2 illustrates the structural representation of another embodiment of Car park payment Parking Meter according to the present invention, and it comprises N the Parking Meter group (N>2) and the second anti-tampering module, and the Parking Meter (M1>2) of M1 in embodiment illustrated in fig. 1 wherein arranged in the Parking Meter group 1.
Also comprise the first anti-tampering module in the Parking Meter group 1, be used to prevent that Parking Meter and communication between terminals in the Parking Meter group from interfering with each other on time or frequency.A kind of embodiment, the first anti-tampering module are used to distribute different frequencies to communicate to Parking Meter in the Parking Meter group and terminal; Another kind of embodiment, the first anti-tampering module is used to distribute the different time to communicate to Parking Meter in the Parking Meter group and terminal, and promptly the call duration time of each Parking Meter separates, and has only a Parking Meter in the Parking Meter group 1 simultaneously in communication, so just can not interfere with each other.
A kind of embodiment, this first anti-tampering module can be arranged in the Parking Meter group 1 in some Parking Meters, and this Parking Meter can be referred to as main Parking Meter, and other Parking Meters are called the branch Parking Meter.
In the present embodiment, the second anti-tampering module is used to prevent that the Parking Meter of each Parking Meter group and communication between terminals from interfering with each other on frequency, promptly distribute different frequencies to give each Parking Meter group, frequency and terminal that the Parking Meter in the Parking Meter group is distributed according to Parking Meter, place group communicate.
Above content be in conjunction with concrete embodiment to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
