Abstract

The utility model provides a meet water warning schoolbag, includes the schoolbag, is equipped with the string bag in schoolbag both sides, is equipped with a plurality of humidity detection module on the schoolbag, and a plurality of humidity detection module are connected with control module's input, and control module's output and alarm module are connected, still include battery module, battery module and control module are connected. The utility model provides a water novel schoolbag of reporting to the police, can remind when rainy day of propping the umbrella or drinking cup leak people behind one's back the schoolbag enough drench, give people with timely warning when have a meal in addition occasionally jardiniere soup or beverage are splashed on the schoolbag.

Description

A kind of chance water warning school bag

Technical field

This utility model relates to a kind of school bag, particularly a kind of chance water warning school bag.

Background technology

General school bag, usual structure includes schoolbag brace, the school bag string bag, slide fastener, the portable rope in top, and usual school bag material is canvas or terylene, is not provided with other devices above.But due to when opening an umbrella walking rainy day, it is impossible to learn that school bag is enough being drenched behind well., can not learn in the very first time when accidentally leaking when being placed on the water tumbler of the string bag, thus avoiding school bag interior items to drench in time meanwhile.Additionally, people are when having a meal in dining room, when chair having water or having vegetable soup or beverage to splash on school bag, can report to the police the very first time and inform that bag master takes measures to be preferably minimized loss in time, to people to remind timely.

Summary of the invention

For solving above-mentioned technical problem, this utility model provides a kind of water novel school bag of warning, can remind people that school bag behind is enough to drench when the rainy day opened an umbrella or water tumbler leak, to people to remind timely when having vegetable soup or beverage to splash on school bag when having a meal in addition.

For solving above-mentioned technical problem, this utility model be the technical scheme is that a kind of chance water warning school bag, including school bag, it is provided with the string bag in school bag both sides, school bag is provided with multiple humidity detecting module, multiple humidity detecting module are connected with the input controlling module, and the outfan controlling module is connected with alarm module；Also including power module, power module is connected with controlling module.

Preferably, the plurality of humidity detecting module be respectively arranged on bottom string bag place, school bag, school bag surface.

Preferably, described alarm module is located at the top of school bag.

Preferably, described power module is accumulator battery.

Preferably, described control module is STC89C51 single-chip microcomputer.

Preferably, described humidity detecting module is DHT11 Temperature Humidity Sensor.

Preferably, described alarm module is buzzer.

Preferably, described control module and power module are installed on the bottom in school bag.

The beneficial effects of the utility model are as follows:

1, utilizing No. 5 accumulator to provide electricity, be protected from weather influences, power good is reliable.

2, simple in construction, installs humidity sensor, reminds whether people's school bag is drenched.

3, owing to only with simple Communication processing, processing module preferably employs single-chip microcomputer, reduce manufacturing cost, control simple and convenient.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is described in further detail:

Fig. 1 is structural representation of the present utility model；

Fig. 2 is the circuit theory diagrams of this utility model control part；

In figure: school bag 1, the string bag 2, humidity detecting module 3, control module 4, alarm module 5, power module 6.

Detailed description of the invention

Water warning school bag is met, including school bag 1 as it is shown in figure 1, a kind of, it is provided with the string bag 2 in school bag both sides, being provided with multiple humidity detecting module 3 on school bag, multiple humidity detecting module 3 are connected with the input controlling module 4, and the outfan controlling module 4 is connected with alarm module 5；Also including power module 6, power module 6 is connected with controlling module 4.

Preferably, the plurality of humidity detecting module 3 be respectively arranged on bottom the string bag 2 place, school bag 1, school bag 1 surface.

Preferably, described alarm module 5 is located at the top of school bag 1.

Preferably, described power module 6 is accumulator battery.

Preferably, described control module 4 is STC89C51 single-chip microcomputer.

Preferably, described humidity detecting module 3 is DHT11 Temperature Humidity Sensor.

Preferably, described alarm module 5 is buzzer.

Preferably, described control module 4 is installed on the bottom in school bag 1 with power module 6.

Operation principle: utilize power module 6 to power for whole device.The humidity data collected is passed to control module 4 by humidity detecting module 3, controls module 4 and is compared thus transmitting an order to alarm module 5 by data.

As shown in Figure 2, when rainy day, knapsack people opened an umbrella walking, fall on school bag envelope if umbrella does not have to block school bag to rainwater after one's death, the moisture signal that humidity sensor DH11 detects is sent to the port of the input of the STC89C51 controlling module by humidity detecting module energy 3 on envelope timely, whether STC89C51 sends triggering command by ordering calculation controls conducting through R4 to 9041, thus the buzzer siren controlled on the portable rope in top sends warning, people are reminded to take measures in time, the bag back of the body is moved, in front or adjustment umbrella, the shielded area increasing school bag backward.In addition; water tumbler or the also not dry umbrella of dress water are placed on the both sides string bag by people; when water tumbler leaks or umbrella seeps water; humidity detecting module 3 in the string bag of both sides can gather humidity data; the timely processing controls alarm module 5 warning reminding people of STC89C51 being conducted to control module in time note taking out water tumbler or wetted umbrella in time; protection interior items is not drenched, and loss is preferably minimized.
