Description
Technical field
The present invention relates to intelligent parking management technical field, applied in particular to a kind of on the ground on plane parking stall
Magnetic and back wave comprehensive detection device and its corresponding control mode.
Background technology
At present, the need for meet city public parking, there is provided the substantial amounts of plane parking stall for public parking.And
These plane parking stalls are occurred in that using geomagnetism detecting technology, the geomagnetism detecting dress for being specially designed for detecting storing cycle in recent years
Put.The Primary Component of geomagnetic sensor is " geomagnetic sensor ", small volume, and road pavement destruction is small during installation, easy to maintenance.Ground
Magnetic Sensor using magnetic field of the earth ferromagnetic object by when change detect, weatherproof, and to nonferromagnetic thing
Body does not react, and can effectively reduce the flase drop to non-vehicle object, report by mistake.But, found in actual application, for
The compact parallel planes parking stall of arrangement, because the distance between geomagnetic sensor is smaller, when the both sides on an empty parking stall
It is also parking stall, and has parked vehicle, then the geomagnetic sensor for being arranged on the sky parking stall easily produces flase drop, missed
Report；If both sides parking stall parked vehicle vehicle body is higher, the probability relative increase that flase drop, wrong report occur.Reduce geomagnetism detecting
The detection sensitivity of device will influence accuracy of detection again simultaneously it is of course possible to reduce the possibility of wrong report, exist awkward.It is above-mentioned
Problem has had influence on further genralrlization application of the geomagnetism detecting technology in public parking field.
The content of the invention

A kind of earth magnetism and back wave comprehensive detection device, it is characterised in that：Described device is applied on plane parking stall,
Including geomagnetism detecting unit, back wave detection unit, column, power supply unit, single machine unit, wireless transmit/receive units.
The geomagnetism detecting unit is arranged on the ground on parking stall, and each parking stall at least installs one, passes through inspection
Whether survey the GEOMAGNETIC CHANGE validation of information parking stall in correspondence parking stall parking region has storing cycle.
The back wave detection unit is ultrasonic detection unit or radar wave detection unit, is arranged on column,
It detects interior zone of the direction towards parking stall, and each parking stall at least installs one, by detecting stopping for correspondence parking stall
Car region judges whether the parking stall has storing cycle indirectly with the presence or absence of barrier.
The each parking stall of column at least installs one, is arranged on a side of parking stall wherein without prejudice to vehicles while passing
On line, for installing back wave detection unit, power supply unit, single machine unit, wireless transmit/receive units.
The each parking stall of said supply unit it is supporting set one, for geomagnetism detecting unit, back wave detection unit,
Single machine unit and wireless transmit/receive units provide electric power, its input access mains system, by transformation, rectification, voltage stabilizing it
Afterwards, as dc source, respectively to geomagnetism detecting unit, back wave detection unit, single machine unit and wireless transmit/receive units
