Technical field
The invention belongs to electronic metering equipment technical field, be specifically related to a kind of food spoilage detection sound broadcasting device.
Background technology
In daily life, everyone is intended to buy, had fresh food, especially summer, the fresh product corruption apt to deteriorate that people buy, and when people have eaten rotten food, health can be brought serious impact.Food is fresh or putrid and deteriorated, generally differentiates from aspects such as its lustrous surface, elasticity, color, hardness and the abnormal smells from the patients that distributes, but it is far from being enough for only having these.At present, whether the commonly used bacterial cultivation detection food of China goes bad, and makes, by measuring the content of certain bacterial flora of food, the conclusion whether food is edible.But this method needs 48 hours assays just can conclude, and the time is long, and efficiency is low.
Summary of the invention
It is an object of the invention to provide a kind of food spoilage detection sound broadcasting device, it may be achieved the measurement of food spoilage, and there is liquid crystal display and voice broadcast measurement result two ways, show the time simultaneously, be suitable for different users and use.
Food spoilage, refers under the effect of a variety of causes based on microorganism, food reduce or lose edibility all change, as meat, egg, fowl rancid, going mouldy of grain, festering of veterinary antibiotics, becoming sour of oils and fats.Water is Source of life, and microbial growth breeding is had important function by it.It is, in general, that when in food, moisture is less than 15%, food would not be putrid and deteriorated.The corruption of food is played catalytic action by temperature, and temperature is high, and the activity of histaminase can strengthen, and the nutritional labeling of food can be decomposed, and bacterial action is more strong, and the more easy corruption of food, then resistance is more little.
The technical solution adopted in the present invention is: food spoilage detection sound broadcasting device, including controlling module, controls module and is connected to sensing module, LCD MODULE, keyboard, real-time clock module and voice broadcast module.Sensor assembly includes A/D modular converter, and A/D modular converter is connected to moisture transducer and resistance detection network.
The feature of the present invention also resides in,
Voice broadcast module includes the voice recording-reproducing assembly, power amplifier module and the loudspeaker that are sequentially connected, and voice recording-reproducing assembly is connected to control module.
The model of moisture sensing module is SMTS-I-50.
The model of A/D modular converter is ADC0809.
The model controlling module is STC89C52.
The model of LCD MODULE is LCD1602.
The model of LCD MODULE is LCD12864.
The model of voice recording-reproducing assembly is SYN6288.
The model of real-time clock module is DS1302.
The invention has the beneficial effects as follows: the food spoilage detection sound broadcasting device of the present invention, adopt moisture transducer and resistance detection network, start with from the resistance of food and moisture the two parameter and detect, and compare with the standard value of fresh food, thus judging the degree of food spoilage, make the judgement that can food eat.Can well eliminate the side-play amount of data, reduce temperature drift and error detection, there is the features such as volume is little, precision is high, good stability, it is to avoid bacterial cultivation detection food time length, portability difference defect；Particularly functional diversities, not only can detect resistance and the moisture of food, and can also thermometric and timing.The data recorded carry out numerical monitor by LCD MODULE, accurate, have the function of voice broadcast simultaneously, facilitate the old people having defective vision and use.
