Low-temperature protection device for raised flag height indicator

Abstract

The invention provides a low-temperature protection device for a raised flag height indicator. The device comprises a casing, a temperature sensor, a temperature control chip and a heat generating unit. The raised flag height indicator includes a power supply, a control chip, a laser ranging sensor, a display screen and a measurement sheet. A low-temperature protection device of the raised flag height indicator and the raised flag height indicator are used together to realize the measurement of a flag height in a low-temperature environment, so a flag raiser can intuitively and reliably provide the real-time display of the position of the flag in a flag raising ceremony and grasp the height of the flag and control a flag-raising speed to complete the flag-raising task well.

Problems solved by technology

The flag-raising ceremony is very particular about the national flag being raised to the top of the flagpole at the end of the national anthem. This time control is very dependent on the experience and daily training of the flag-raiser.
