By the food refreshment reminding device, the freshness of the food is convenient to check and can be effectively known.
Description
Technical field
The present invention relates to a kind of electronic installation, specifically is a kind of food fresh keeping alarm set.
Background technology
In many families, refrigerator has almost become " safety box " of food, no matter eat prepared food raw, also no matter vegetables or meat, as long as one throw away in the refrigerator, just feel on the quality of food insurance.Because modern society's rhythm of life is fast, people forget often and check the freshness of depositing food, though with the food long-term storage in refrigerator; Food still can be corrupt, and when people expected checking that food is whether corrupt, often food was corrupt; Can only abandon, cause waste.
Usually people judge the food freshness through naked eyes and sense of smell, even some food is corrupt, also are difficult to discover, in a single day eat by mistake this moment, can produce infringement to health.Therefore be badly in need of a kind of food freshness that is convenient for people to check, and can effectively learn the equipment of food freshness.
Summary of the invention
To the problem that above-mentioned prior art exists, it is a kind of food freshness that is convenient for people to check that the present invention provides, and can effectively learn the food fresh keeping alarm set of food freshness.
To achieve these goals, the technical scheme of the present invention's employing is: a kind of food fresh keeping alarm set comprises:
Microprocessing unit: inside is provided with determining program, when gas sensor test when the situation of food is lower than the preset standard value in the determining program, microprocessing unit promptly sends information warning through the caution unit;
Display: show the food gas values that gas sensor is sensed, be connected with microprocessing unit;
The caution unit: electrically connect with microprocessing unit, microprocessing unit sends information warning through the caution unit;
The control button: through control key control device switch, and the preset value of setting the inner food situation of microprocessing unit, the control button is connected with microprocessor;
Gas sensor: electrically connect with microprocessing unit, be used to obtain food emission gases information, the situation of sensing food.
Operation principle: gas sensor can become voltage output to convert to gas with foreign flavor intensity-conversion in the air can be by the information of personnel's utilization; Therefore this device is sensed the peculiar smell of depositing food through gas sensor; Convert digital information to; Be transferred to microprocessor processes, whether fresh, corrupt through the relevant food of data comparison reminds people.
The present invention utilizes the smell information of gas sensor sensing food; Whether the numerical value that the determining program of in device, setting compares sensing is lower than the preset standard value of setting; Demonstrate through unit and display the information of warning again, be convenient for people to check intuitively food freshness, thereby whether the knowledge food of in time judging addles food; In time edible, cut the waste; The gas sensor induction is sensitive, and the ability actual induction is to the smell information of food; This device uses such as crisper or refrigerator of can arranging in pairs or groups in addition, the convenient use.
Description of drawings
Fig. 1 is a principle of the invention block diagram.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
As shown in Figure 1, a kind of food fresh keeping alarm set of the present invention comprises:
Microprocessing unit: inside is provided with determining program, when gas sensor test when the situation of food is lower than the preset standard value in the determining program, microprocessing unit promptly sends information warning through the caution unit;
Display: show the printed words of the fresh or putrid food of food, be connected with microprocessing unit;
The caution unit: electrically connect with microprocessing unit, microprocessing unit sends information warning through the caution unit;
Control module: through control module control device switch, and the preset value of setting the inner food situation of microprocessing unit, control module is connected with microprocessor;
Gas sensor: electrically connect with microprocessing unit, be used to obtain food emission gases information, the situation of sensing food.Gas sensor can become voltage output to convert to gas with foreign flavor intensity-conversion in the air can be by the information of personnel's utilization.
This device can also add wireless delivery unit and external interface in addition.
Wireless delivery unit is connected with microprocessing unit, is used for numerical value behind the gas sensor sensing is sent to communication apparatus, and like mobile phone, computer etc., person easy to use monitors the state of freshness of the food of depositing in real time, in time handles.
Wireless delivery unit can select for use infrared ray or RF a kind of data of carrying out wherein to transmit.
External interface is connected with microprocessing unit, is used for being connected with external computer equipment carrying out system upgrade, communication.External interface is set can be used to connect external computer equipment and connect and to carry out system upgrade, also can with this device internal induction to storage to computer, do the usefulness of statistics backup.
The course of work: at first through control button preset standard value in microprocessing unit; With this device gas sensor partly place the food of depositing next door, gas sensor sense the smell that food sends; Convert current signal to and be sent to microprocessing unit; Microprocessing unit can will show the food gas values through display equipment on the one hand, perhaps be presented to communication apparatus through wireless delivery unit, like mobile phone, computer etc.On the other hand; Preset standard value contrast in the current signal of conversion and the microprocessing unit; When the situation (smell numerical value) of sensing food when gas sensor is lower than in the microprocessing unit in the determining program preset standard value; This microprocessing unit promptly sends information warning by the caution unit, and this information warning can be the LED lamp, or buzzer etc.
