Miniature astronomical telescope demisting heating tape control device

The utility model discloses a small astronomical telescope demisting heating tape control device, which comprises a power supply circuit, a key circuit, an stm8 core control circuit, a temperature measurement circuit, a display circuit and a heating switch circuit, and relates to the technical field of electronic control. According to the utility model, any temperature difference can be set, heating can be effectively and dynamically controlled, and power consumption is reduced; and secondly, in terms of design cost, temperature measurement and control can be realized by selecting an 8-bit stm8 single chip microcomputer which is low in price and extremely low in power consumption and a thermocouple, and display of a multi-bit nixie tube can be carried out by adopting a serial-to-parallel chip 74HC595 and only consuming three IO ports of the single chip microcomputer under the condition that IO of a display circuit is insufficient. 本实用新型公开了一种小型天文望远镜除雾发热带控制装置，包括电源电路、按键电路、stm8核心控制电路、测温电路、显示电路以及加热开关电路，本实用新型涉及电子控制
