Description

Toilet behavior detection system

The present invention relates to a toilet behavior detection system, especially a toilet behavior detection system that can recognize the actions of users.

Improper behaviors such as voyeurism, sneak photography, abduction, and theft that occur in public toilets are increasing, and the toilets are often set up in more remote locations such as buildings, parks, schools, etc., with relatively few people coming and going, which is a big deal for those interested Places prone to crime. Most of the crimes in the toilet are to hide in the toilet cubicle and wait for the opportunity, and the latecomers often enter by one person and use it without knowing it, giving the gangster a chance to take advantage of it. In the prior art, it can only show whether there is someone in the toilet, and it is impossible to know whether the user has abnormal behavior in the toilet cubicle.

Therefore, it is necessary to create a newly designed toilet behavior detection system to solve the lack of previous technology.

The main purpose of the present invention is to provide a toilet behavior detection system, which has the effect of identifying abnormal behaviors of users.

In order to achieve the above-mentioned purpose, the toilet behavior detection system of the present invention is used to detect the movements of users in seemingly unmanned compartments in the toilet, and can be connected to a remote monitoring system. The toilet behavior detection system includes a detector, a processing module and a wireless transmission module. The detector is used to sense the movement of the user in the toilet cubicle to obtain the detection signal. The detection signal received by the processing module is used to determine whether the user has abnormal behavior, thereby generating an abnormal signal. The wireless transmission module is electrically connected to the detector and the processing module, and is used to transmit the detection signal and the abnormal signal to the remote monitoring system through the wireless transmission path.

In order to allow your reviewer to better understand the technical content of the present invention, a preferred specific embodiment is described as follows.

Please refer to Figure 1 for the schematic diagram of the toilet behavior detection system of this creation.

In the present embodiment of the invention, the toilet behavior detection system 1 is used to detect the movement of a user 3 in a toilet cubicle 2 so as to know whether the user 3 has normal or abnormal behavior. Normal behaviors can include opening the door to enter and exit, sitting on the toilet or squatting on the toilet. Abnormal behaviors include standing for a long time, prolonged tummy, standing on the toilet or clinging to the partition, but this creation does not use the above-listed Behavior is limited. The toilet behavior detection system 1 includes a detector 10, a processing module 20, a wireless transmission module 30 and an alarm device 40. The detector 10 is used to sense the movement of the user 3 to obtain a detection signal. In an embodiment of this creation, the detector 10 is a Frequency Modulated Continuous Wave (FMCW) radar, and is arranged outside the door of each toilet cubicle 2. FM continuous wave radar can transmit high-frequency and wide-bandwidth signals. After the signal reaches the target, it will be reflected back to the receiver. In this way, the distance to the target and the relative moving speed can be calculated from the time delay and frequency offset of the signal. Therefore, the detection signal obtained by the detector 10 can include a movement speed change signal and a height change signal, which are used to detect the position change with the user 3, including the height position of the user 3, and can also know the use The direction of movement of the person 3. The detector 10 can start detection when the user 3 opens the door of the toilet cubicle 2 to enter the toilet cubicle 2, and stops detection when the user 3 opens the door of the toilet cubicle 2 again and leaves the toilet cubicle 2.

The processing module 20 is used to receive the detection signal to determine whether the user 3 has an abnormal behavior using the algorithm of behavior recognition. If the processing module 20 confirms that there is an abnormal behavior, it generates an abnormal signal. Please also refer to Figure 2 for the curve of the detection signal change of this creation.

The detection signal obtained by the detector 10 can be divided into a moving speed change signal curve S1 and a height change signal curve S2 as shown in FIG. 2, and FIG. 2 also includes different time points T1 to T4. At time T1, it means that there is no user 3 in the toilet cubicle 2. At this time, the moving speed change signal curve S1 and the height change signal curve S2 will maintain the original curve. At the time point T2, the user 3 enters the toilet cubicle 2, and the moving speed change signal curve S1 will generate a high convex wave, thereby representing the movement of the user 3. At this time, the height change signal curve S2 will also change because of the user 3. Then, between time points T3 and T4, when the user 3 is about to stand on the toilet, the height change signal curve S2 will also change significantly. The processing module 20 may first record a preset normal signal, which is the movement speed change signal curve S1 and the height change signal curve S2 during the normal behavior of the user 3, such as the curve from time point T1 to T2, or It is the curve when the user 3 normally sits on the toilet, squats on the toilet, or uses the squatting toilet. When the moving speed change signal curve S1 or the height change signal curve S2 is significantly different from the normal curve, such as the curve at time points T3 and T4, the processing module 20 confirms the abnormal behavior through calculations, and generates an abnormal signal. The processing module 20 can also send an abnormal signal after the abnormal behavior continues for a specific time, for example, 5 or 10 seconds, so as to reduce the probability of false alarms. Therefore, when there is any abnormal behavior, including standing for a long time, lying on the stomach for a long time, standing on the toilet or clinging to the partition, the processing module 20 can be judged by the moving speed change signal curve S1 or the height change signal curve S2 .

The wireless transmission module 30 is electrically connected to the detector 10 and the processing module 20, and is used to transmit the detection signal and the abnormal signal to a remote monitoring system 4 using a wireless transmission path, such as Wi-Fi transmission , But this creation is not limited to this, this creation can use any transmission module. The remote monitoring system 4 can be a monitoring center or a police notification system, whereby all conditions can be recorded for data analysis, and the police notification system can directly intervene for processing when necessary. The alarm device 40 is used for emitting an alarm signal according to the abnormal signal. The alarm device 40 includes a light module 41 or an audio module 42. That is, the light module 41 can be used to emit a warning light such as a red warning light, or the audio module 42 can be used to emit a warning sound, but this creation does not Limited to this. In addition, when the processing module 20 confirms that the behavior of the user 3 is not an abnormal behavior, for example, when the user 3 is normally sitting on the toilet, squatting on the toilet, or using a squatting toilet, the light module 41 can also emit lights with different lights. , Such as a green display light, it means that this toilet cubicle 2 is being used.

It should be noted that the modules of the toilet behavior detection system 1 can be constructed by hardware devices, software programs combined with hardware devices, firmware combined with hardware devices, etc., but this creation is not in the above manner Is limited.
