The invention provides an intelligent shell
temperature control system of a
traditional Chinese medicine fumigation therapeutic apparatus, which comprises a
power processing circuit, a keyboard
control circuit, an LCD (
liquid crystal display) displaying circuit, a voice and alarm circuit, a
single chip microcomputer system circuit, an A / D (analog / digital) conversion circuit, a
laser ranging sensor, an environment temperature sensor, a shell temperature sensor, a pot internal
steam temperature sensor, a pot internal
steam pressure sensor, an
EPROM (electrically programmable read-only-memory) circuit, an optocoupler, a
silicon controlled
thyristor and an
electric heating film. An embedded
single chip microcomputer is utilized as a control core, by means of measuring pot internal
steam pressure and temperature, heating of the
electric heating film is controlled in a closed-loop manner, constant output flow of steam is guaranteed, the
system sets steam
contact temperature by the aid of a user keyboard according to a
relational table of environment temperature stored by an
EPROM, steam
contact shell temperature and the distance from a steam outlet to the shell of the body of a user, an LCD displays the position and the
contact temperature of the
human body in real time, the
human body is prompted to move so as to reach a proper distance in a voice manner, and when the
contact temperature is over high and
skin of the user is easy to be injured, the system alarms and cuts off a power source. The intelligent shell
temperature control system is simple in structure, low in manufacturing cost, convenient in operation, stable in performance and high in intelligent degree.
