The elevator multimedia terminal is a new generation intelligent device which utilizes display terminals such as a display and a television to realize information display or video advertisement playing in the modes of multimedia control, wireless communication and the like.
Because the elevator car has a strong electromagnetic signal shielding effect, no 4G/5G signal coverage exists in the elevator car, or the 4G/5G signal coverage is poor, as shown in figure 2. The existing elevator multimedia terminal adopts a built-in antenna mode, as shown in fig. 1, the built-in antenna has small gain or no gain, so that the elevator multimedia terminal in an elevator car cannot be connected with a wireless network or is not well connected with the wireless network, and the elevator multimedia terminal cannot acquire information such as advertisements and notifications from a network server or cannot acquire information such as advertisements and notifications from the network server in time. When the elevator multimedia terminal cannot be connected to a network or is not connected well, the information such as advertisements and notifications can only be copied to the elevator multimedia terminal by using the storage medium in a manual mode, and the manual copying mode is adopted, so that time and labor are wasted, timely release of the information such as advertisements and notifications cannot be guaranteed, and the utilization rate of the elevator multimedia terminal is reduced and the operation cost is increased.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned not enough, provide an elevator multimedia terminal with 4G/5G wireless communication function, can be in the elevator car in not having 4G/5G signal, or when 4G/5G signal is not good, also can be connected to on the 4G/5G network better.
In order to achieve the purpose, the utility model comprises an elevator multimedia terminal arranged in an elevator car and an antenna arranged outside the elevator car, wherein a communication module is arranged in the elevator multimedia terminal, a connector is arranged on the elevator multimedia terminal, the communication module is connected with the connector, and the connector is connected with the antenna;
the communication module is used for controlling the antenna to receive and transmit 4G/5G signals.
The connector is connected with the antenna and the communication module is connected with the connector through radio frequency lines.
The radio frequency line adopts a 3D-FB radio frequency line.
The connector is a radio frequency connector.
The antenna can be replaced with a large gain directional antenna or a lightweight antenna.
The antenna is placed on top of the elevator car.
Compared with the prior art, the utility model discloses with antenna mounting in the outside mode of elevator car, the successful shielding of having evaded elevator car to telecommunication signal, and external antenna can select reasonable gain's antenna according to actual 4G 5G signal strength in the elevator shaft to reach the elevator multimedia terminal in the elevator car and have good radio signal and receive and the emission effect. The utility model discloses can not have the 4G 5G signal in elevator car, perhaps when the 4G 5G signal is not good, also can be connected to the 4G 5G network to can obtain information such as notice, advertisement from network server in real time, and then promote elevator multimedia terminal's result of use, improve elevator multimedia terminal's utilization ratio, reduce elevator multimedia terminal's operation cost.
Further, the utility model discloses an antenna can select according to actual conditions is nimble to satisfy the business demand, the management requirement of property.
