2, external antenna of the present utility model is installed in the refrigerator door upper end, built-in aerial is built-in to be installed on the refrigerator display panel, dual-antenna system is combined with refrigerator display screen PCB, simple in structure, cost is low, effectively guaranteed signal strength signal intensity, layout is succinctly reasonable simultaneously, does not affect the overall appearance of refrigerator outside.
3, the control method of the refrigerator with double antenna of the present utility model by detection, judgement, the selection to receiving and transmitting signal, is finally determined the antenna of current demand signal intensity optimum; Subsequently by verification and remember the selection situation of current antenna, add their confirmation, guarantee the refrigerator connecting wireless network, all the time use the antenna of signal strength signal intensity optimum in the time of receiving and transmitting signal, guarantee signal resource reasonable distribution and use switching between built-in aerial and the external antenna, effectively enlarge simultaneously the coverage of signal transmitting and receiving, improve the quality of signal transmission.
Description of drawings
Fig. 1 is double antenna of the present utility model installation site schematic diagram;
Fig. 2 is control structure schematic diagram of the present utility model;
Fig. 3 is control flow chart of the present utility model.
Among the above-mentioned figure:
The 1-external antenna, 2-built-in aerial, 3-refrigerator body, 4-refrigerator display screen.
The specific embodiment
As shown in Figure 1, the refrigerator with double antenna of present embodiment, comprise refrigerator body 3 and antenna, its antenna comprises built-in aerial 2 and external antenna 1, external antenna 1 is installed in the refrigerator doors top on refrigerator top, and external antenna 1 receives and the zone of transmitted signal covering is in the inverted cone zone take the refrigerator top as the vertex of a cone.
Built-in aerial 2 is installed on the refrigerator display screen 4, and the zone that the reception of built-in aerial 2 and transmitted signal cover is with in the inverted cone zone of refrigerator dead ahead take display screen as the vertex of a cone.
As shown in Figure 3, the control method with the double antenna refrigerator of present embodiment comprises following content:
(1) readiness: behind system's 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, then uses external antenna frames received certificate greater than critical point-65dBm; If its signal strength signal intensity, is then selected built-in aerial frames received certificate less than critical point-65dBm;
(3) judge, select: and detect antenna receiving signal intensity, after comparing, select preferably antenna reception frame data of signal strength signal intensity;
(4) verification, memory: the frame data that receive are carried out the CRC/FCS verification, if successfully by verification, then remember the selection of current antenna, and use simultaneously this antenna as transmitting antenna; If frame data are failed then to return by verification (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 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 |
| Efficient | 54.5% | 55.3% | 56.5% | 56.9% | 55.8% | 55.1% |
The operating efficiency of the built-in aerial 2 of 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 |
| Efficient | 25.6% | 26.3% | 28.6% | 30.1% | 31.3% | 27.8% |
By the above table data as seen, external antenna 1 operating efficiency is higher than built-in aerial 2, so the dual-antenna system acquiescence is selected external antenna 1 for the work antenna and detected its signal strength signal intensity.When external antenna 1 signal strength signal intensity is weak, switch to the signal strength signal intensity that built-in aerial 2 also compares built-in aerial 2 and external antenna 1, selecting than the powerhouse is the work antenna.
Need to prove that also employed double antenna has essential distinction with the double antenna diversity receiving technology of at present extensive use in the utility model.Double antenna diversity receiving technology is the signal that a plurality of antennas of signal focus utilization that disperse to obtain is received simultaneously 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 utility model is the external structure that takes full advantage of refrigerator, two kinds of antennas are installed in respectively in refrigerator doors top and the refrigerator display screen, the signal transmitting and receiving coverage of two kinds of antennas is different, be vertical complementation on the direction, farthest guarantee the coverage of signal, by comparing the received signal strength selection work antenna of antenna, can effectively prevent the impact that the stop signal multipath is weak and refrigerator shielding itself causes, effectively guarantee signal strength signal intensity.
The above, only be to preferred embodiment of the present utility model, be not to be that the utility model is done other forms of restriction, 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 utility model scheme content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment does, still belongs to protection domain of the present utility model according to technical spirit of the present utility model.
