The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
The invention is described in further detail below with reference to the attached drawing figures:
in order to make up the performance of the existing antenna and not to influence the appearance, the universal clamp of the police terminal is just utilized, and a group of antennas are arranged on the universal clamp to make up the problem of poor antennas on part of the police terminal.
For this reason, as shown in fig. 1, the present invention provides an optimizing apparatus for an external antenna of a police terminal, comprising a police terminal 10 and a gimbal 20; which is an improvement over the prior art police terminal 10 and gimbal 20.
Wherein:
the conventional police terminal 10 comprises a slot 11 and a clamping slot 12, wherein an internal antenna of 4-5 antennas (a 2/3/4G main set antenna, a 2/3/4G diversity antenna, a wifi & BT antenna, a GPS antenna and a private network antenna) is arranged in the police terminal, an external antenna of 4-5 antennas is arranged outside the police terminal, and the external antenna is connected with the internal antenna to form a complete 4-5 antenna structure. The existing universal clamp 20 comprises a plug 21 and a clamping head 22, when the universal clamp 20 is installed, the plug 21 of the universal clamp 20 is inserted into the slot 11 of the police terminal 10, after the plug is inserted into place, the clamping head 22 of the universal clamp 20 is just clamped in a clamping groove of the police terminal 10, so that the police terminal 10 and the universal clamp 20 are fixed, and then the universal clamp is hung in front of the chest of police personnel; in normal use, the police terminal 10 and the universal clip 20 are fixed together without disassembly.
The invention is based on the prior police terminal and universal clamp, and the improvement is that:
according to the actual use conditions of 4-5 antennas, the environment is usually poor, parameters are poor, a weak signal cannot search a network or the network is unstable, and a part of external antennas with poor use experience are arranged on the universal clamp 20; in fig. 1, it is shown that one external antenna 23 (which may be a GPS antenna or an external network antenna) is arranged on a gimbal, while the internal antennas and the remaining external antennas of all antennas are not changed, but are still designed in corresponding positions and maintain the connection of the existing internal and external antennas. Meanwhile, in addition to the arrangement of one external antenna in the gimbal 20 shown in fig. 1, one or more external antennas may be selected to be arranged on the gimbal; the principle is the same as the following.
The invention takes the GPS external antenna 23 as an example and sets up on the universal clip, the setting up principle of it is explained as follows:
because the GPS external antenna 23 is arranged on the universal clamp, how to connect the GPS external antenna 23 with the existing GPS internal antenna in the police terminal needs to be considered; therefore, the contactor of the external antenna and the internal antenna is required to be designed to realize the connection of the internal antenna and the external antenna; for this purpose, the invention sets up the contact point 24 that links with GPS external aerial 23 on the universal clip 20, there are contacts 13 on the police terminal 10; because the police terminal 10 and the universal clip 20 are buckled at the slot 11 and the plug 21, the bottom of the slot 11 is further provided with the contact 13, and the position of the plug 21 corresponding to the contact 13 is provided with the contact point 24; when the plug 21 of the universal clip 20 is buckled in the slot 11 of the police terminal 10, the contact between the contact 13 and the contact point 24 is just realized, so that the GPS external antenna 23 on the universal clip 20 can be connected with the GPS internal antenna in the police terminal 10.
Furthermore, the contactor capable of realizing the above functions can be selected from the conventional spring pin contactor or cable line contactor, and the spring pin contactor or cable line contactor is of a conventional contactor structure, so the structure and principle thereof are not described in detail herein.
Furthermore, the connection mode of an external antenna is shown, if two external antennas are arranged on the universal clip, 2 contacts and contact points are correspondingly arranged, the specific arrangement positions are around the plug and the slot, and finally, the contact is just guaranteed to be connected with the contact points after the plug is inserted into the slot.
Further, the external antenna is directly attached to the gimbal 20.
Further, the external antenna is an omni-directional antenna, a PIFA antenna or an LVDS antenna.
The invention also provides an optimization method based on the optimization device, which comprises the following steps:
judging whether the contact is in contact with the contact point or not;
if the external antenna is not in contact with the internal antenna, judging that the external antenna is not inserted, and enabling the internal antenna to work;
if the external antenna is in contact with the external antenna, the external antenna is judged to be inserted, and the external antenna works.
Wherein,
the invention is composed of an external antenna circuit (existing antenna) on the police terminal and an antenna on the universal clamp, and the external antenna circuit and the antenna on the universal clamp form an external antenna whole. When the universal clip is buckled, the spring pin (also can be in a cable line contact mode) on the terminal is contacted with the antenna on the universal clip, and the switching circuit on the board can automatically switch the antenna from the internal antenna to the external antenna. Because the universal clamp is provided with a plurality of surfaces which can be used as the antenna, the antenna has excellent environment and is far away from the intelligent terminal body, the interference is reduced, and the antenna performance can be optimal.
The invention has the advantages that:
according to the invention, the performance of the antenna can be improved by placing part of external antennas on the universal clamp, so that a new solution idea is provided for a scheme with multiple antennas and insufficient antenna areas; the problem that the performance of the antenna is poor in a weak environment can be better solved, and the user experience and the product competitiveness are greatly improved.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
