The specific embodiment
As shown in Figure 1, the refrigerator with double antenna of the present embodiment, comprise refrigerator body 3 and antenna, its antenna comprises 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 the region of transmitted signal covering is to take in the inverted cone region that refrigerator top is 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 transmitted signal cover is to take in the inverted cone region that display screen is the vertex of a cone with refrigerator dead ahead.
As shown in Figure 3, the control method with double antenna refrigerator of the present embodiment, comprises following content:
(1) readiness: after system power-up initializing, acquiescence is carried out idle listening to external antenna;
(2) detect packet: external antenna data bag is detected, if its received signal strength is greater than critical point-65dBm, use external antenna frames received certificate; If its signal strength signal intensity is less than critical point-65dBm, select built-in aerial frames received certificate;
(3) judgement, selection: and detect antenna receiving signal intensity, after comparing, select the good antenna reception frame data of signal strength signal intensity;
(4) verification, memory: the frame data that receive are carried out to CRC/FCS verification, if successfully by verification, remember the selection of current antenna, and use this antenna as transmitting antenna simultaneously; If frame data are failed, by verification, to return (1) readiness and are reselected.
Wherein, the external antenna 1 two kind PCB antennas different from built-in aerial 2 operation parameter performances.After tested, the operating efficiency of the external antenna 1 of the present embodiment 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, so dual-antenna system acquiescence is selected external antenna 1 for work antenna and detects its signal strength signal intensity.When external antenna 1 signal strength signal intensity is weak, switch to built-in aerial 2 and also compare the signal strength signal intensity of built-in aerial 2 and external antenna 1, selecting is work antenna compared with powerhouse.
Also it should be noted that, the double antenna using in the present invention has essential distinction with the double antenna diversity receiving technology of extensive use at present.Double antenna diversity receiving technology is a plurality of antennas of signal focus utilization that disperse to obtain to be received simultaneously to the signal in different paths, then these signals are selected, are merged into resultant signal, as long as be separate between several signals, after appropriate merging, just can obtain maximum signal gain.And double antenna design of the present invention is the external structure that makes full use of refrigerator, two kinds of antennas are arranged on respectively in refrigerator doors top and refrigerator display screen, the signal transmitting and receiving coverage of two kinds of antennas is different, in direction, be vertical complementation, farthest guarantee the coverage of signal, by the received signal strength selection work antenna of antenna relatively, can effectively anti-stop signal multipath weak and refrigerator itself shield the impact causing, effectively guarantee signal strength signal intensity.
The above, be only to preferred embodiment of the present invention, is not that the present invention is done to other forms of restriction, and any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every the present invention program's content that do not depart from, to any simple modification made for any of the above embodiments, equivalent variations and remodeling, still belongs to protection scope of the present invention according to technical spirit of the present invention.
