Description
Technical field
The invention belongs to hand-held ultrasound apparatus fields.It is related to medical ultrasound imaging diagnostic device, and in particular to one kind is used for
The wireless antenna layout method of hand-held ultrasound equipment.
Background technique
Handheld device must could be connect, to realize portability by hand-held ultrasound equipment using wireless transmission with client.
Sensitive to wireless transmission signal since hand-held ultrasound equipment volume is small, the layout of antenna will seriously affect the steady of transmission transmission
It is qualitative.
Therefore, the position of wireless antenna or layout necessarily realize the key of this wireless connection.
Summary of the invention
It is an object of that present invention to provide a kind of wireless antenna layout methods for hand-held ultrasound equipment.The present invention can drop
The influence of low wireless signal is conducive to the speed for improving wireless transmission.
In order to achieve the above objectives, technical solution of the present invention is as follows:
A kind of wireless antenna layout method for hand-held ultrasound equipment, comprising the following steps:
S1 show that hand-held ultrasound equipment can be used for the position of antenna installation according to the structure and requirement of hand-held ultrasound equipment, and
Antenna is respectively deployed in these positions according to the form of permutation and combination, obtains antenna arrangement scheme；
Assuming that the wavelength of wireless signal is that the pairing of maximum λ 1, minimum λ 2, two aerial position distance L relationship is satisfied with:
L=(λ 1+ λ 2)/4,
Two pairing antenna angle α relationships are satisfied with:
90 ° of α=n *, n is integer
The most frequent equipment posture that S2 is used according to hand-held ultrasound equipment, selects the direction of aerial radiation, determines antenna in machine
Position in shell: far from probe, the discontiguous hand-held ultrasound of operator's human body sets two sides of tail region, and shell distance d0:
D0 > n* λ 1, for the integer greater than 1
S3 wireless antenna PCB or shielding distance d1 inside hand-held ultrasound equipment:
D1 > n* λ 1, for the integer greater than 1
Wireless antenna is placed in handheld device top plastic housing interlayer or close to apex zone by S4, multiple groups antenna be divided into it is longitudinal and
Cross direction profiles.
Further, the MIMO technology of wireless transmission is made full use of, the speed of wireless transmission can be greatly improved.
The utility model has the advantages that antenna is placed in close to top and two sides by the present invention, interfered far from internal circuit, far from heat dissipation gold
Belong to, far from shielding metal, effectively enhances the quality of antenna receiving and transmitting signal.Further, since antenna, on top, handheld device makes
With in the process, finger will not be touched near antenna；Essentially eliminate finger influences aerial signal recklessly.
Detailed description of the invention
