The following figures are used to further explain the mobile public toilet maintenance system and method of the present invention using the Internet of Things. Please refer to "Figure 1" first. "Figure 1" is the system of the mobile public toilet maintenance system using the Internet of Things of the present invention. Block diagram, this system includes: a mobile public toilet 110 and a server 120. The mobile public toilet 110 includes a sensing module 111 and a transmission module 112. The sensing module 111 is used to obtain positioning coordinates through a positioning system, and to sense the number of uses of the mobile public toilet 110, the number of toilet papers, and the sanitation status through sensing elements. In actual implementation, the number of locks on the door panel of the mobile public toilet 110 can be sensed as the number of uses, the number of toilet paper extractions can be sensed to estimate the number of toilet paper, the taste in the mobile public toilet 110 can be sensed to determine the sanitary status, etc. As for the positioning system The Global Positioning System (GPS), Beidou Navigation Satellite System (BDS), Galileo or similar systems can be used to obtain the positioning coordinates.

The transmission module 112 is electrically connected to the sensing module 111 for transmitting the positioning coordinates and the sensed number of uses, the number of toilet paper and the sanitary status to the server 120. In actual implementation, the transmission module 112 can transmit and receive data in a wired or wireless manner, so that the mobile public toilet 110 has a network connection function. In addition, the transmission module 112 can also receive a questionnaire through the Internet for the user to fill in, so that after the user completes the questionnaire, the mobile public toilet 110 provides an appropriate amount of toilet paper for the user to use.

The server 120 includes a receiving module 121, a detecting module 122, a notification module 123, and a reporting module 124. Among them, the receiving module 121 is used to receive the positioning coordinates, the number of times of use, the quantity of toilet paper, and the sanitation status from the mobile public toilet 110. In actual implementation, the receiving module 121 of the server 120 can receive through any wired or wireless means, and is not limited to the Internet of Things.

For example, assuming that the preset number is "50", when it is sensed that the number of toilet paper in a mobile public toilet 110 is less than the preset number, a corresponding maintenance message is generated. This maintenance message includes the location coordinates of the corresponding mobile public toilet 110 . In this way, it can be clearly known which mobile public toilet 110 needs to be cleaned by the maintenance message. In actual implementation, the maintenance message can simultaneously record all mobile public toilets 110 that meet the conditions (ie: the number of toilet papers is less than the preset number and the sanitary status is poor or either) and their positioning coordinates.

The notification module 123 is electrically connected to the detection module 122 for sending the generated maintenance message to the maintenance end device to notify the maintenance personnel to go to the corresponding mobile public toilet 110 for maintenance and cleaning according to the positioning coordinates in the maintenance message. In actual implementation, the maintenance end device may be a mobile device such as a smart phone, a tablet computer, a notebook computer, and a personal digital assistant of the maintenance personnel, or a computer device such as a personal computer and a server. In addition, the positioning coordinates can be displayed together with map information or Geographic Information System (GIS), so that maintenance personnel can quickly go to the corresponding mobile public toilet 110 for cleaning.

The report module 124 is electrically connected to the receiving module 121 to analyze the positioning coordinates of the mobile public toilet 110 to generate a distribution topology, and adjust the distribution topology according to the number of uses to generate a setting suggestion report. In actual implementation, the distribution topology is to present the positioning coordinates in the form of nodes, and each node corresponds to a usage count. When adjusting the distribution topology, the nodes with less usage times will be closer to the nodes with more usage times. , Or directly add a new node at the location of the node that is used more frequently as the recommended location for the mobile public toilet 110. In this way, the administrator can evaluate how to adjust the location of the mobile public toilet 110 from the distribution topology in the setting recommendation report, or where to add the mobile public toilet 110 to better divert the flow.

When the user responds to the questionnaire survey, the toilet paper supply device is driven to provide toilet paper. In actual implementation, the driving module 113 can also detect the completion degree of the questionnaire, and load the paper value according to the completion degree and the preset paper supply correspondence table, and then drive the toilet paper supply device to provide the toilet paper quantity corresponding to the paper value. The paper supply correspondence table contains the correspondence relationship between the completion degree and the paper value. For example, assuming the completion degree is "25%", the corresponding paper value can be the value "1", which represents a piece of toilet paper; assuming the completion degree " 50%", the corresponding paper value can be the value "2", representing two sheets of toilet paper, and so on. When the completion degree is "50%", the corresponding paper value can be the value "4", representing four sheets toilet paper.

In addition, the server 120 to which the present invention is applied may further include a screening module 125, which is electrically connected to the receiving module 121, for each positioning coordinate as the current coordinate, and filtering out the current coordinate Other positioning coordinates within N kilometers are used as recommended coordinates, and the recommended coordinates are transmitted to the mobile public toilet 110 that matches the current coordinates for display, where N is a positive integer. In actual implementation, the screening module 125 can also be electrically connected to the detection module 122 at the same time to filter out the coordinates that do not match the positioning coordinates in the maintenance message among the recommended coordinates, and then send the filtered recommended coordinates To the mobile public toilet 110 that matches the current coordinates for display. In this way, when the mobile public toilet 110 is in use, the user can follow the suggested coordinates to go to the nearby unused mobile public toilet 110.

Next, please refer to "Figure 2A" to "Figure 2C". "Figure 2A" to "Figure 2C" are the method flowcharts of the mobile public toilet maintenance method using the Internet of Things according to the present invention. In the network environment of the server 120 and the server 120, the steps include: the mobile public toilet 110 obtains the positioning coordinates through the positioning system, and senses the number of uses of the mobile public toilet, the amount of toilet paper, and the sanitary status through the sensing element (step 210); 110 transmits the positioning coordinates and the number of times of use, the amount of toilet paper and the sanitation status sensed to the server 120 (step 220); the server 120 has less than the preset number of toilet paper in the mobile public toilet 110 and the sanitation status is not good or both At a time, a maintenance message containing the positioning coordinates of the mobile public toilet 110 is generated (step 230); the server 120 sends the generated maintenance message to the maintenance end device to notify the maintenance personnel to go to the corresponding mobile public toilet 110 to maintain and clean according to the positioning coordinates in the maintenance message (Step 240); The server 120 analyzes the positioning coordinates of the mobile toilet 110 to generate a distribution topology, and adjusts the distribution topology according to the number of uses to generate a setting suggestion report (Step 250). Through the above steps, the positioning system can be installed in the mobile public toilet 110 to obtain the positioning coordinates, and different sensing elements can be set to sense the number of uses, the number of toilet paper, and the sanitary state, and the positioning coordinates, the number of uses, the number of toilet paper, and the sanitary state can be determined. It is sent to the server 120. When the server 120 detects that the amount of toilet paper is insufficient, the sanitary condition is not good, or either, it generates a maintenance message containing the positioning coordinates to notify the maintenance personnel to go to maintenance, and generates a setting suggestion report based on the number of uses.

In addition, after step 220, the mobile public toilet 110 may display the received questionnaire and allow the user to respond to the questionnaire. When it is detected that the user responds to the questionnaire, the mobile toilet 110 drives the toilet paper supply device to provide Toilet paper (step 221). In addition, after step 230, the server 120 can respectively use each received positioning coordinate as the current coordinate, and filter out other positioning coordinates within N kilometers of the current coordinate circle as the recommended coordinate, and send the recommended coordinate to the current coordinate. The mobile toilets 110 with matching coordinates are displayed, where N is a positive integer (step 231).

The following description will be given in conjunction with "Figure 3" and "Figure 4" in the form of an embodiment. Please refer to "Figure 3" first. "Figure 3" is a schematic diagram of applying the present invention to prompt cleaning and generating a setting suggestion report. In actual implementation, no matter whether the mobile public toilet 300 is in use, it will continue to obtain the positioning coordinates through the positioning system, and continuously sense the number of uses and toilet paper of the mobile public toilet 300 through different sensing elements (311, 321 and 331). Quantity and sanitation status. For example, the sensing element 311 can be an odor sensor to sense ammonia, odor, etc. When the concentration of ammonia and odor exceeds the allowable range, the sanitation status is judged to be poor , Otherwise, it is judged that the sanitary condition is good; the sensing element 321 can be set in the toilet paper supply device 320 to sense the use state of the toilet paper to estimate the remaining amount of toilet paper; the sensing element 331 can be set at the door lock for use The cumulative number of locks is used as the number of uses. Then, the mobile public toilet 300 transmits the positioning coordinates and the sensed number of uses, the amount of toilet paper, and the sanitary status to the server 120. The server 120 indicates that the number of toilet paper in the mobile public toilet 300 is less than the preset number and the sanitary status is poor or In either case, a maintenance message including the positioning coordinates of the mobile public toilet 300 is generated. At this time, the server 120 sends the generated maintenance message to the maintenance device 350 to notify the maintenance personnel to go to the corresponding mobile public toilet 300 for maintenance and cleaning according to the positioning coordinates in the maintenance message. In addition, the server 120 also analyzes the positioning coordinates of the mobile public toilet 300 to generate a distribution topology, and adjusts the distribution topology according to the number of uses to generate a setting recommendation report. In this way, it can be ensured that the mobile public toilet 300 is maintained in a certain clean state, and the manager can also adjust the installation position of the mobile public toilet 300 through the distribution topology in the setting recommendation report, so that the utilization rate of all the mobile public toilets 300 is more even. In particular, the mobile public toilet 300 can also be provided with a touch screen 341 inside and a display 342 outside. The touch screen 341 can display questionnaires and allow users to respond to the questionnaires. When the user responds to this questionnaire, the toilet paper supply device 320 can be driven to provide toilet paper. As for the display 342, when the mobile public toilet 300 is in use, it can display suggested coordinates to instruct the waiting user to go to other mobile public toilets 300. In other words, the suggested coordinates represent the coordinate positions of other mobile public toilets 300 within a radius of N kilometers of this mobile public toilet 300. In this way, you can avoid waiting for a long time and achieve the purpose of diversion.

As shown in "Figure 4", "Figure 4" is a schematic diagram of applying the present invention to adjust the distribution topology. As mentioned earlier, the distribution topology is to present the positioning coordinates in the form of nodes, and each node corresponds to a number of times of use. When adjusting the distribution topology, the nodes with less use times will be closer to the nodes with more times. Or, directly add a new node at the location of the node that is used more frequently as the location where the mobile public toilet 110 is recommended. In actual implementation, the setting suggestion report 400 can be as shown in "Figure 4", showing the distribution topology of the mobile public toilet 110 in the form of nodes (411~415), and each node (411~415) corresponds to a usage count. For example: the usage count corresponding to node 411 is "102", the usage count corresponding to node 412 is "254", the usage count corresponding to node 413 is "625", the usage count corresponding to node 414 is "113" and node 415 corresponds to The number of uses is "224". Then when adjusting the topology, because node 413 is used the most times, followed by node 412, node 415, node 414, and node 411 in order, the recommended node 421 can be generated directly at the position of node 413 with the most use, and as As shown in "Figure 4", it is suggested that the node 421 is slightly adjusted to the direction of the node 412 and the node 415 at the same time. In this way, the manager can learn from the distribution topology in the setting suggestion report 400 that adding the mobile public toilet 110 at the location of the suggestion node 421 can better play a role of diversion and improve the rationality of the distribution of the mobile public toilet 110.

To sum up, it can be seen that the difference between the present invention and the prior art is that the positioning system is installed in the mobile toilet to obtain the positioning coordinates, and different sensing elements are set to sense the number of uses, the number of toilet paper and the sanitary state, and the positioning coordinates are , Use times, toilet paper quantity, and hygiene status are sent to the server. When the server detects that the number of toilet papers is insufficient, the hygiene status is poor, or either, it generates a maintenance message containing the positioning coordinates to notify the maintenance personnel to go to maintenance, and according to The usage frequency generates a setting suggestion report, and this technical means can solve the problems of the prior art, and then achieve the technical effect of improving the cleanliness and rationality of distribution of the mobile public toilet.
