Abstract

The invention discloses a city canopy and a control method thereof. The city canopy comprises a truss, a curtain, a curtain retraction device, a sensor and an electrical control device. The sensor isarranged on the truss. The sensor is used for detecting the pressure of the truss and generating a pressure value signal. The electrical control device is electrically connected with the sensor. The electrical control device is used to receive the pressure value signal sent by the sensor. If the pressure value signal is greater than a preset pressure value, the curtain retraction device is controlled to retracting the curtain. According to the city canopy and the control method thereof, the electrical control device is used to receive the pressure value signal sent by the sensor in real time and comparing the pressure value signal with the preset pressure value; if the pressure value signal is greater than the preset pressure value, the electrical control device sends out a curtain retracting command and controls the curtain retraction device to retract the curtain; the stress of the truss is reduced; accidents are effectively prevented; and significant economic losses are avoided.

Description

technical field [0001] The invention relates to the technical field of outdoor activity sky screens, in particular to an urban sky screen and a control method thereof. Background technique [0002] City canopy is a kind of curtain used to project slides in performances. It can change different scenes according to the development of the plot during the performance. Under the action of slides and lights, it shows mountains, rivers, lightning, thunder, storms, Scenes such as the quiet countryside allow the audience to experience the magnificent plot and give the audience a sense of being there. [0003] At present, most of the urban sky screens are set outdoors (such as riversides, lakesides, seasides, etc.), which not only provides enough space for the sky screen layout, but also brings the audience a good visual effect because of its good visual landscape effect. Comes with an excellent look and feel experience, so the user experience is high. However, since the urban canop...
