Detailed description of the invention
As it is shown in figure 1, the refrigerator with double antenna of the present embodiment, including refrigerator body 3 and antenna, its antenna includes
Built-in aerial 2 and external antenna 1, external antenna 1 is arranged on the refrigerator doors top on refrigerator top, and external antenna 1 receives and sends out
In the region that the number of delivering letters covers is the inverted cone region with refrigerator top as the vertex of a cone.
Built-in aerial 2 is arranged on refrigerator display screen 4, and the region that the reception of built-in aerial 2 and transmission signal cover is with ice
In the inverted cone region with display screen as the vertex of a cone, the case dead ahead.
Refrigerator display screen 4 is set on refrigerator body 3, refrigerator display screen 4 arranges Antenna Selection Module, functional switch and letter
Number process MCU, its system architecture is as shown in Figure 2.
As it is shown on figure 3, the control method with double antenna refrigerator of the present embodiment, including following content:
(1) readiness: after system electrification initializes, acquiescence carries out idle listening to external antenna；
(2) detection packet: external antenna data bag is detected；
(3) judge, select: if external antenna received signal strength is more than critical point-65dBm, then use external antenna frames received
According to；If external antenna signal strength signal intensity is less than critical point-65dBm, then detection built-in aerial signal strength signal intensity, after comparing, select
Signal strength signal intensity preferable antenna frames received evidence；
(4) verifying, remember: the frame data received are carried out CRC/FCS verification, if successfully passing verification, then the day before yesterday is worked as in memory
The selection of line, and use this antenna as launching antenna simultaneously；If frame data fail by verification, then return (1) readiness
Reselect.
Wherein, external antenna 1 uses two kinds of PCB antenna that performance parameters is different from built-in aerial 2.After tested, this enforcement
The operating efficiency of the external antenna 1 of example is as shown in table 1:
Table 1 external antenna operating efficiency
| Frequency (GHz) | 2.40 | 2.42 | 2.44 | 2.46 | 2.48 | 2.49 |
| Efficiency | 54.5% | 55.3% | 56.5% | 56.9% | 55.8% | 55.1% |
The operating efficiency of the built-in aerial 2 of the present embodiment is as shown in table 2:
Table 2 built-in aerial operating efficiency
| Frequency (GHz) | 2.40 | 2.42 | 2.44 | 2.46 | 2.48 | 2.49 |
| Efficiency | 25.6% | 26.3% | 28.6% | 30.1% | 31.3% | 27.8% |
From above table data, external antenna 1 operating efficiency is higher than built-in aerial 2, and therefore dual-antenna system acquiescence selects
External antenna 1 is for work antenna and detects its signal strength signal intensity.When external antenna 1 signal strength signal intensity is more weak, switch to built-in aerial
2 and compare the signal strength signal intensity of built-in aerial 2 and external antenna 1, select relatively powerhouse for work antenna.
Also, it should be noted the double antenna used in the present invention has with the double antenna diversity receiving technology being widely used at present
Essential distinction.Double antenna diversity receiving technology is that the multiple antenna of signal focus utilization that dispersion is obtained receives different path simultaneously
Signal, then by these signal behavior, be merged into resultant signal, as long as being separate between several signal, through appropriate conjunction
The signal gain of maximum just can be obtained after and.And the double antenna design of the present invention is the external structure making full use of refrigerator, by two kinds
Antenna is separately mounted in refrigerator doors top and refrigerator display screen, and the signal transmitting and receiving coverage of two kinds of antennas is different, on direction in
Vertical complementary, farthest ensures the coverage of signal, by comparing the received signal strength selection work antenna of antenna,
Can the most anti-stop signal multipath is weak and refrigerator itself shields the impact caused, effectively ensure signal strength signal intensity.
The above, be only to presently preferred embodiments of the present invention, be not the restriction that the present invention does other forms, appoints
What those skilled in the art is changed possibly also with the technology contents of the disclosure above or is modified as the equivalence of equivalent variations in fact
Execute example.But, every without departing from the present invention program content, the technical spirit of the foundation present invention is to made for any of the above embodiments any
Simple modification, equivalent variations and remodeling, still fall within protection scope of the present invention.
