Embodiment 1

[0036] Please refer to figure 1 , this embodiment provides, a communication device applied to an underground parking lot, used to communicate with a remote server, has a communication module 1 and a transmitting module 2, the transmitting module 2 includes an antenna unit and a gain unit, the The antenna unit is connected to the communication module 1; the antenna unit is used to transmit a communication signal and receive a response signal from a remote server, and the communication module 1 is used to generate a communication signal and process the response signal; the The gain unit is detachably connected to the antenna unit for amplifying the signal strength of the communication signal and the response signal.

[0037] When the signal strength of the antenna unit is weak when communicating in the underground parking lot, the gain unit can enhance the sent communication signal and the received response signal to solve the problem of weak signal strength of the communication...

Embodiment 2

[0044] Please refer to figure 2 , in this embodiment, on the basis of Embodiment 1, the gain unit has a plurality of directional antennas 27, a plurality of electronic switches 28 corresponding to these directional antennas 27, and a controller 22; each directional antenna 27 passes The corresponding electronic switch 28 is connected to the controller 22, and the controller 22 controls the working status of each directional antenna 27 by controlling each electronic switch 28; these directional antennas 27 are used for directional sending communication signals and directional receiving response signals, And each directional antenna 27 corresponds to a different direction. The controller 22 can control the electronic switch 28 connected to the directional antenna 27 to close when the signal strength of the response signal received by the directional antenna 27 is lower than the preset threshold strength, and the directional antenna 27 is arranged on the second on the cover bod...

Abstract

The invention provides a communication device applied to an underground parking lot for communicating with a remote server. The communication device is provided with a communication module and a transmitting module, the transmitting module comprises an antenna unit and a gain unit, and the antenna unit is connected with the communication module; the antenna unit is configured to transmit a communication signal and receive a response signal sent by the remote server, the communication module is configured to generate a communication signal and process the response signal; and the gain unit is detachably connected to the antenna unit and is configured to amplify the signal strength of the communication signal and the response signal. In the underground parking lot, the situation that the communication signal strength is weak or even the connection is interrupted often occurs. The communication device provided by the invention adds the gain unit to the antenna unit, so that when the signal strength is weak, the gain unit can be connected to the antenna unit to enhance the signal strength of the antenna unit.

Description

technical field [0001] The invention relates to the communication field, in particular to a communication device applied to an underground parking lot. Background technique [0002] Nowadays, with the popularity of the Internet of Things, more and more things have gradually entered the era of the Internet of Everything. Due to the limitations of the use environment, many IoT devices often cannot use wired communication but can only use wireless communication. However, in an environment such as an underground parking lot, due to strong wireless signal interference, the strength of the communication signal will be weak or even the connection will be directly interrupted, which will affect the use. Contents of the invention [0003] The invention provides a communication device applied to an underground parking lot, aiming at improving the problem of weak signal strength of the existing communication device in underground communication. [0004] The present invention is ach...
