The present invention relates to the field of smart home, in particular to a signal integrated terminal.
With the rapid social development, the level of people's economic life is increasingly improved, the household appliances in households and office environment are increasing, people's operation of household appliances also becomes more and more complicated, besides, owing to the different operating manners of various household appliances, it requires for certain learning costs and purchase costs, and it causes inconvenience for people's life. At the same time, many household appliances, such as doorbell, TV signal receiver, router, etc., shall be placed in a clear space easy to been seen to affect the overall aesthetic appearance of the house. Further, it is inconvenient to use them separately, particularly that the TV signal receiver and the router have more line connections including at least signal lines and power lines, moreover, the TV signal receiver and the router is generally placed together with a TV set and a computer, respectively, such areas have complex lines, resulting in quite inconvenience in repair and maintenance of the TV signal receiver and the router.
In order to overcome the problems of the prior art, the present invention provides a signal integrated terminal capable of simultaneously integrating wireless communication with TV signal receiving, at least comprising a housing, an antenna module and a circuit module, wherein the antenna module comprises a first antenna for receiving TV signals and a second antenna for receiving and transmitting wireless signals, which are both matched with the housing and respectively electrically connected with the circuit module arranged in the housing.
The present invention comprises two antenna types which can cover the common household antenna types to meet the use of common terminals nowadays. The two types of antennas are integrated in one device, so that the user can reduce the purchase cost without buying and installing different devices separately, besides, the user only needs to repair and maintain one device, namely the integrating terminal, which reduces the operating complexity. Particularly, when it is used on a moving traffic vehicle, such as automobile, ship or plane, it can save a big space for installation and reduce the wiring.
Further, the polarities of the first antenna and the second antennas are mutually orthogonal.
Since multiple different antennas are integrated in the same housing, the working frequencies of the first antenna (with the frequency band of TV signals of 88 MHz-230 MHz and 470 MH-700 MHz) and the second antennas (the wireless signals are generally WiFi signals, of which the frequency band is 2412 MHz-2483 MHz) range from dozens of MHz to thousands of MHz, therefore the anti-interference design in radio frequency is especially important. The crucial problem to be solved is to avoid the mutual interference among different signals, and thus, the polarities of the antennas are mutually orthogonal and the radiation charts of the antennas are in cross distribution, which avoids the mutual interference among the antennas.
Further, the circuit module comprises a TV signal module electrically connected with the first antenna, used for receiving TV signals, and a wireless communication module electrically connected with the second antennas, used for receiving and transmitting wireless signals.
The wireless communication module is configured to realize the function equivalent to a wireless router, and it can both realize the relaying function and transmit wireless signals as an access point.
Further, the wireless communication module is a wireless router or a repeater.
Further, the terminal also comprises a signal conversion module electrically connected with the TV signal module, used for converting the received TV signals into WiFi signals. In this way, when the TV signal module receives TV signals from the second antenna, the TV signals can also be transmitted by the wireless communication module to the user terminals, such as computer, mobile phone, tablet PC, etc., so that it will be more convenient for users to watch TV to improve the user experience.
Further, TV signal module comprises a resolution adjusting module electrically connected with the signal conversion module, used for adjusting the resolution of the TV signals according to the code rates of the signals and the different terminals wirelessly communicated with the signal conversion module.
Since the wireless signals have different code rates, when the wireless signal has a slower code rate, that is, the wireless signal has a slower transmission speed, it is necessary to reduce the data size of the TV signals by compressing the resolution, for convenience of the users to watch the videos fluently. Besides, the user terminals, such as tablet PC, computer, mobile phone, etc., have different screen sizes and can adapt to different resolutions, therefor, according to the present invention, the resolution can be adaptively adjusted according to the models of different terminals, at least it will not result in the phenomena of incomplete image display and black edging, etc., and it is favorable for improving the user experience in watching.
Further, the TV signal module also comprises a format conversion module electrically connected with the signal conversion module, used for converting different TV signal formats into the same format.
Since there are different TV video formats in various regions and the TV signals may have the formats of MP4, H.264, etc., the format conversion module is configured to convert different video formats into the same format for convenience of uniform coding and packaging into WiFi signals.
Further, the second antenna are flexible patch antennas.
Further, the first antenna comprises a VHF antenna for receiving VHF signals and a UHF antenna for receiving UHF signals, which are both electrically connected with the TV signal module.
Further, the TV signal module comprises a multi-level mixed trap circuit electrically connected with the UHF antenna and used for inhibiting the signals lower than 470 MHz.
Since the UHF may receive signals of other frequency bands, it is necessary to inhibit the signal frequencies except the frequency bands of TV signals, so as to acquire more accurate TV signals and reduce the interference.
Further, the TV signal module comprises an LTE filter electrically connected with the UHF antenna and used for inhibiting signals from mobile phones. Since the UHF may receive signals from mobile phones, it is necessary to inhibit the signal frequencies except the frequency bands of TV signals, so as to acquire more accurate TV signals and reduce the interference.
Further, the VHF antenna are telescopic antennas arranged outside the housing. The telescopic antennas have the advantages that they can rotate t freely and may allow to align with the optimal receiving direction while watching.
Further, the UHF antenna is a flake vibrator arranged inside the housing. The flake vibrator with light weight occupying a small space can reduce the space occupied in the housing.
Compared with the prior art, the utility model has desirable advantages that multiple antennas for receiving different wireless signals are integrated in the same device, on one hand, it can simultaneously realize the functions of receiving TV signals, transmitting and receiving wireless signals, etc.; on the other hand, it is unnecessary for the user to buy multiple different devices and arrange wires, respectively, accordingly, it greatly improves the convenience in use and maintenance. The integrating terminal also arranges the antennas reasonably to maximally reduce the interference among their signals and improve the effect of heat radiation, and its weight is reduced as much as possible for convenience of carrying and use.
The present invention will be explained in details combining with the specific embodiments and drawings below.
