Abstract
The utility model relates to a dual-antenna wireless transmission electromagnetic instrument comprising a casing. A touch screen is arranged at the top of the casing, a circuit board is arranged in the casing, a receiving antenna and a transmitting antenna are arranged on the circuit board, the receiving antenna is arranged on the inner wall of one side of the casing, the transmitting antenna is arranged on the inner wall of the other side of the casing, the receiving antenna and the transmitting antenna are arranged symmetrically, the circuit board is arranged at the bottom of the casing and located at the bottoms of the receiving antenna and the transmitting antenna, a WIFI (wireless fidelity) module is arranged on the circuit board, the signal output end of the WIFI module is connected with the transmitting antenna via a cable, and the signal input end of the WIFI module is connected with the receiving antenna through a cable. By the dual-antenna wireless transmission electromagnetic instrument, interference among signals is avoided effectively, the antennas are protected beneficially, and convenience is brought to maintenance; the WIFI module and the electromagnetic instrument share the transmitting antenna and the receiving antenna, so that interference between the two is effectively prevented, and occupancy on large space is avoided.
Description
Technical field
The utility model relates to a kind of wireless transmission electromagnetic instrument, relates in particular to a kind of wireless transmission electromagnetic instrument of double antenna.
Background technology
At present, the antenna of electromagnetic instrument is all in casing, to be symmetrical arranged and a certain area, spatial placement need to be set in addition, or antenna is arranged to casing outside, and this displacement structure all can affect the signal between antenna, while making reception and transmitted signal, interfere with each other, be unfavorable for the transmission of signal, WIFI module also needs antenna on the other hand, normally by an antenna is being set, signal is each other disturbed, the space also taking.
Utility model content
The technical problems to be solved in the utility model is, for the deficiencies in the prior art, and provides a kind of wireless transmission electromagnetic instrument of double antenna.
The utility model solves the technical scheme that its technical problem adopts: comprise casing, the top of described casing is provided with touch-screen, in it, be provided with wiring board, on described wiring board, be provided with reception antenna and transmitting antenna, described reception antenna is arranged on a side inwall of described casing, described transmitting antenna is arranged on the opposite side inwall of described casing, described reception antenna and described transmitting antenna are symmetrical arranged, the bottom that described wiring board is arranged at described casing is positioned at the bottom of described reception antenna and described transmitting antenna, on described wiring board, be provided with WIFI module, the signal output part of described WIFI module is connected by cable with described transmitting antenna, the signal input part of described WIFI module is connected by cable with described reception antenna.
Implement the technical solution of the utility model, there is following beneficial effect: the utility model is by being arranged on reception antenna and transmitting antenna on the inwall of symmetrical both sides of casing, object is not placed at its middle part, effectively avoid the interference between signal, also be conducive to protect antenna, make to keep in repair more convenient; WIFI module and electromagnetic instrument share transmitting antenna and reception antenna on the other hand, have effectively prevented interference between the two, also can not take very large space.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the structural representation of the wireless transmission electromagnetic instrument of a kind of double antenna described in the utility model.
In figure: 1-casing, 2-touch-screen, 3-reception antenna, 4-transmitting antenna, 5-wiring board, 6-WIFI module, 7-cable.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model comprises casing 1, the top of casing 1 is provided with touch-screen 2, in it, be provided with wiring board 5, on wiring board 5, be provided with reception antenna 3 and transmitting antenna 4, reception antenna 3 is arranged on a side inwall of casing 1, transmitting antenna 4 is arranged on the opposite side inwall of casing 1, reception antenna 3 and transmitting antenna 4 are symmetrical arranged, the bottom that wiring board 5 is arranged at casing 1 is positioned at the bottom of reception antenna 3 and transmitting antenna 4, on wiring board 5, be provided with WIFI module 6, the signal output part of WIFI module 6 is connected by cable 7 with transmitting antenna 4, the signal input part of WIFI module 6 is connected by cable 7 with reception antenna 3.
The utility model is by reception antenna 3 and transmitting antenna 4 are arranged on the both sides inwall of casing 1, and any components and parts are not placed at its middle part, makes the signal between antenna can phase mutual interference, is conducive to the transmission of signal; Line loss bad time on the same day, can open casing 1 and change antenna, keep in repair more convenient.
