Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.
The embodiment provides a thing networking diaphragm gas table based on directional antenna, includes:
the gas meter main body can directly adopt the universal Internet of things membrane type gas meter in the market at present, and can also be a corresponding device capable of realizing the function of the gas meter by other modes such as customization, modification and the like.
The directional antenna is arranged on the gas meter main body and comprises a base 1, a reflecting plate 2 and an antenna radiation unit 3.
In other embodiments, in order to achieve a better 4G signal receiving effect, the base 1 of the directional antenna is mounted on the top of the gas meter body in a sticking manner. The shape of the base is not limited, and in the specific embodiment, the base can be exemplified as a truncated cone shape.
In the specific implementation mode, the reflecting plate 2 of the directional antenna is a hemispherical surface, a circular hole is reserved in the hollow middle part, and the base 1 penetrates through the circular hole and is adhered to the gas meter. The 4G signal can be better blocked and reflected to the antenna radiation unit position in front by the reflector plate which is a hemispherical surface, so that the signal intensity at the antenna radiation unit position is enhanced.
In a specific embodiment, the shape of the antenna radiating element is not limited, and is illustrated as a cylinder in this embodiment. The antenna radiation unit 3 is connected with the base 1 in a spherical hinge mode, and the angle of the antenna radiation unit can be adjusted at will in the spherical hinge connection mode, so that signals can be received better. A locking device is arranged on the base 1 and is a locking bolt 6. After the antenna radiation unit can be locked to be aligned to a certain direction through the advancing and retreating of the locking bolt, the direction of the antenna radiation unit is not changed any more.
And one end of the feeder line 4 is electrically connected with the antenna radiation unit 3, and the other end of the feeder line is electrically connected with an internet of things chip 5 in the gas meter, and is used for signal transmission between the internet of things chip and the directional antenna.
The working principle of the embodiment 1 is described in detail below, and an internet of things membrane gas meter based on a directional antenna is referred to as a gas meter for short:
the gas meter of this embodiment is installed inside the kitchen by the construction developer. After the house is checked and accepted by the owner, when the gas company in the local area is connected to the gate and the gas is opened, the staff of the gas company can adjust the angle of the antenna radiation unit of the directional antenna. Specifically, a worker of a natural gas company carries a 4G signal strength tester with him, finds the strongest direction of the 4G signal at the position of the gas meter in a kitchen, and then manually adjusts the direction of the antenna radiation unit, so that the direction of the antenna radiation unit is opposite to the strongest direction of the 4G signal. And then adjusting the locking bolt to lock the direction of the antenna radiation unit. Thus, the strength of the received 4G signal can be greatly enhanced by using the directional antenna at a position where the strength of the original 4G signal is weak.
In a specific implementation mode, the size of an internal oscillator of the antenna radiation unit for communicating with a 4G network can be within 30mm in length and within 3mm in width, and the cylindrical shape of the antenna radiation unit can be within 40mm in length and within 5mm in diameter. The diameter of the spherical surface of the reflecting plate of the directional antenna can be 50mm, and the installation is convenient.
Through the technical scheme of this embodiment, through directional antenna, can strengthen the 4G signal intensity of receiving by a wide margin, make the thing networking chip of gas table can keep with management center's real-time communication, avoid because 4G signal intensity is relatively weak, thereby lead to the unable normal and management center communication of thing networking diaphragm type gas table.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
