Description
Technical field
The present invention relates to communication technical field, more particularly to a kind of stall testing apparatus.
Background technology
Using spring antenna earth magnetism wagon detector on the market at present, its bandwidth is general in 10MHz or so, Qie Yishou roads more
The influences of external environment such as base material matter, immersion, accumulated snow and change operational resonant point.
PIFA antennas are named so that its side structure and the English alphabet F outward appearances turned one's coat are identical.The operation of PIFA antennas
Length only has a quarter operative wavelength, and has included grounding metal plane in its structure, can reduce in module
The susceptibility of grounding metal plane, so being extremely suitable for use in bluetooth module device.On the other hand, because PIFA antennas only need profit
With the appropriate feed-in of metallic conductor cooperation and antenna short circuit to the position of ground plane, therefore its low manufacture cost, and can be direct
Weld together with PCB.The metallic conductor of PIFA antennas can use wire or sheet, if with Metal Flake making
Then may be designed as the purpose that SMD components reach hiding antenna to weld on circuit boards.Now in order to support sheet metal not with connect
Ground metal covering produces short circuit, it will usually the medium of insulation is added between sheet metal and ground plane, if using dielectric constant
Isolation material (Dielectric Constant) higher can also reduce the size of Bluetooth antenna.
The content of the invention
In view of this, the invention provides a kind of stall testing apparatus, using PIFA antenna frames in certain circumstances,
Under buried environment, model can as far as possible be focused on the top of antenna, intersect spring antenna pattern, signal is utilized
Rate lifting more than 50%, effective bandwidth up to 40MHz, communication distance 300m, considerably beyond communication distance of the prior art and
In the case of product is by water submerged or snow cover, impedance value and resonance point to antenna change smaller (generally less than 2MHz).
Therefore, the technical solution adopted in the present invention is：A kind of stall testing apparatus, described device includes being used for monitoring car
The sensor of Geomagnetism Information on position；For the wireless launcher of data communication, for analyzing, calculating, arrange Geomagnetism Information
Equipment manager；The sensor is electrically connected with the wireless launcher；The wireless launcher and the equipment control
Device is electrically connected by PIFA antennas；
The PIFA antennas also include ground plane, feeder line plate and radiating element；The feeder line plate is electrically connected with radiating element
Connect.
Further, the feeder line plate includes feeder line and ground strip.
Further, the PIFA antennas approximate resonance point is by equation below gained：
F=c/ (4L)
Wherein L：It is radiating element feed line length；
C:It is ray velocity.
Further, described device also includes warning device, and the warning device is signal lamp, the warning device
Electrically connected with the equipment manager.
The beneficial effects of the invention are as follows：A kind of stall testing apparatus, using PIFA antenna frames in certain circumstances,
Under buried environment, model can as far as possible be focused on the top of antenna, intersect spring antenna pattern, signal utilization rate
Lifting more than 50%, effective bandwidth up to 40MHz, communication distance 300m, considerably beyond communication distance of the prior art and product
In the case of product are by water submerged or snow cover, impedance value and resonance point to antenna change smaller (generally less than 2MHz).
