Roll paper monitoring device and roll paper monitoring method

Abstract

The invention discloses a roll paper monitoring device, which comprises an infrared emission sensor arranged in a roll paper box, an infrared receiving sensor, a control module, a switch and a clientside connected with the control module; wherein the infrared emission sensor and the infrared receiving sensor are arranged on the same horizontal line on the two sides of the inner wall of the roll paper box respectively; the control module is fixed in the roll paper box, and is connected with the infrared emission sensor and the infrared receiving sensor; the switch is arranged on the control module. By the roll paper monitoring device provided by the invention, manual checking whether the roll paper of each toilet is used up or not is not needed, so that manpower resource is saved; accurateroll paper replacement time is provided, and the detection error of the residual roll paper does not exceed 2 mm.

Description

technical field [0001] The invention relates to the field of object monitoring and early warning, in particular to a use monitoring and information feedback device for toilet roll paper. Background technique [0002] For a long time, the use of roll paper has been judged by manual inspection, that is, when people find that there is no roll paper in the roll paper box, they know that it needs to be replaced. Such as figure 1 As shown in the figure, the roll paper box used to place the roll paper is mainly used as a container, and has no monitoring and early warning function itself. [0003] In recent years, with the rapid development of the service industry and the continuous improvement of people's living standards, paper rolls that were originally only used in households are increasingly provided in toilets in public places, such as shopping plazas, hotels, office buildings, and teaching buildings. Wait. For the replacement of roll paper in the above-mentioned larger pub...

AI Technical Summary

Problems solved by technology

[0004] And in above-mentioned places, the replacement of toilet paper is often not timely, and people still often encounter the embarrassing situation that there is no toilet paper when going to the toilet

This is because the cleaning staff cannot know the usage status of the roll paper, and the regular replacement method adopted cannot meet the real-time consumption of the roll paper

Especially in public places with a large flow of people, the number of visitors fluctuates greatly due to the influence of time and region (for example, the number of visitors to shopping malls will increase significantly during holidays, and the number of visitors to toilets near certain beverage store areas will be higher than other locations toilets, etc.), the periodic replacement method is less reliable in terms of timely replenishment of roll paper - it ignores the complex and changing demand for roll paper in actual scenarios

Even if a relatively reasonable roll paper replacement time is obtained based on experience or statistical data, there is still a certain deviation between the estimated time and the actual consumption time, which leads to the fact that there are always people who use the toilet without toilet paper, and good users cannot be achieved. experience requirements

[0005] In addition to the shortcomings of untimely replacement, the manual inspection method also has the problem of wasting manpower and time

[0006] Due to the evacuation of the toilets, the cleaning personnel need to spend a lot of time and energy to check every place, but not every roll paper needs to be replaced every time they check, which causes a waste of manpower and time

like image 3 As shown, it shows the floor plan of a large shopping center. The red circle marks the location of the restrooms (two men and women in each place). Assume that the shopping center has 6 floors, each floor covers an area of ​​20,000 square meters, and there are 6 restrooms. Clean Each person needs to carry 36 paper rolls with a diameter of 20cm ( figure 2 ) to check each restroom in turn and replenish the used rolls. Not only is it inconvenient to move, but it takes at least half an hour to reach each destination point, wasting a lot of manpower and time
