Abstract
The invention discloses an overtemperature acousto-optic alarm device of a constant-temperature drying oven, and relates to the technical field of electronics. The device comprises a temperature sensor arranged in the constant-temperature drying oven, wherein the temperature sensor is used for real-time induction of a temperature condition in the constant-temperature drying oven, is connected with a singlechip, and transmits an acquired temperature signal to the singlechip; the singlechip analyzes and processes the temperature signal, and is connected with an acousto-optic alarm and an LED (light-emitting diode) display screen; after the temperature sensor transmits the acquired temperature signal to the singlechip, the singlechip analyzes and processes the temperature signal; and when temperature in the constant-temperature drying oven is greater than a set value through analysis, the singlechip starts the acousto-optic alarm for alarming, and real-time temperature is displayed on the LED display screen. After the acousto-optic alarm device is mounted additionally, a worker does not require more time to concern the constant temperature, and can do other work with more time, so that the labor efficiency of the worker is improved, the constant-temperature drying safety of a product is improved well, and a potential safety hazard of a fire is reduced greatly.
Description
Technical field
The present invention relates to electronic technology field, be specifically related to a kind of constant temp. drying box overtemperature acoustic-optic alarm.
Background technology
Baking oven is to utilize the heating of heating wire interlayer to make the dry equipment of object.It is applicable to than the baking and banking up with earth of room temperature high 5～300 ℃ (what have is high 200 ℃) scope, be dried, thermal treatment etc., and sensitivity is generally ± and 1 ℃.The model of baking oven is a lot, but basic structure is similar, generally casing, electric heating system and automatic temperature control system three parts, consists of.An existing baking-box function constant temperature is in a temperature spot or high and low temperature point.While reaching the high temperature of setting with regard to auto-breaking, just heating while reaching low warm spot.If the contacts of contactor sintering on baking oven, or fan blower do not turn, and dries the temperature inside the box and raises rapidly, very likely burns out product, even fire hazard in baking oven.
Summary of the invention
It is a kind of highly sensitive that technical matters to be solved by this invention is to provide, the constant temp. drying box overtemperature acoustic-optic alarm that actual application value is good.
Technical matters to be solved by this invention realizes by the following technical solutions:
A kind of constant temp. drying box overtemperature acoustic-optic alarm, comprise that one is arranged at the temperature sensor in thermostatic drying chamber, this temperature sensor is for responding in real time the temperature regime in thermostatic drying chamber, described temperature sensor is connected with single-chip microcomputer, the temperature signal collecting is transferred to single-chip microcomputer, by single-chip microcomputer, carry out analyzing and processing, described single-chip microcomputer is connected with audible-visual annunciator and LED display, when temperature sensor is transferred to the temperature signal collecting after single-chip microcomputer, single-chip microcomputer carries out analyzing and processing, when freeze-day with constant temperature the temperature inside the box is learnt in analysis higher than setting value, this single-chip microcomputer starts audible-visual annunciator and reports to the police, and in LED display, show real time temperature.
Described audible-visual annunciator is arranged on the upper left corner of constant temp. drying box, is convenient to actual observation.
Described temperature sensor is pressed close to the fan blower in thermostatic drying chamber.
Described temperature sensor is connected with single chip communication by Wireless Transmitter.
The invention has the beneficial effects as follows: after the present invention installs, workman pays close attention to temperature regime while not taking, can do other work the more time, improve workman's efficiency, also improve well the security of freeze-day with constant temperature of product and the potential safety hazard that greatly reduces fire simultaneously.
Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, a kind of constant temp. drying box overtemperature acoustic-optic alarm, comprise that one is arranged at the temperature sensor 1 in thermostatic drying chamber, this temperature sensor 1 is for responding in real time the temperature regime in thermostatic drying chamber, temperature sensor 1 is connected with single-chip microcomputer 2, the temperature signal collecting is transferred to single-chip microcomputer 2, by single-chip microcomputer 2, carry out analyzing and processing, single-chip microcomputer 2 is connected with audible-visual annunciator 3 and LED display 4, when temperature sensor 1 is transferred to the temperature signal collecting after single-chip microcomputer 2, single-chip microcomputer 2 carries out analyzing and processing, when freeze-day with constant temperature the temperature inside the box is learnt in analysis higher than setting value, this single-chip microcomputer 2 starts audible-visual annunciator 3 and reports to the police, and show real time temperature in LED display 4.Audible-visual annunciator 3 is arranged on the upper left corner of constant temp. drying box, is convenient to actual observation, and temperature sensor 1 is pressed close to the fan blower in thermostatic drying chamber.
More than show and described ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and instructions, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
