Description

Technical Field

[0001] The utility model relates to the technical field of RFID detection, and in particular to an intelligent detection system based on RFID. Background Art

[0002] With the development of social economy, the diaper market has entered a stage of rapid development. When using diapers, they are usually in direct contact with the user's skin. Although diapers have strong moisture absorption capacity, their air permeability is generally poor. Therefore, if diapers are not replaced in time after being wetted by urine, wet diapers can easily cause damage to the user's skin. In particular, the skin of infants, the elderly, the paralyzed, and the incontinent is very fragile. Wet diapers can easily cause bedsores or even rot on the skin of infants, the elderly, the paralyzed, and the incontinent, seriously affecting the quality of life of users.

[0003] At present, there are some diapers with wetness display function on the market. After being wetted by urine, some areas of the outer surface of these diapers will change color, etc., thereby serving as a reminder of wetness. Although these diapers can serve as a reminder of wetness, caregivers need to check the diapers frequently, and such reminders are usually difficult to be discovered in time at night. In addition, when taking care of infants, the elderly, paralyzed people, and incontinent people, caregivers also need to check their sleep conditions regularly to ensure their health status, which not only takes up a lot of caregivers' time, but also consumes a lot of caregivers' energy. Therefore, providing a technology that can simultaneously detect the user's sleep condition and the urine condition of the diaper has become an urgent problem to be solved by technicians in this field. Utility Model Content

[0004] The purpose of the utility model is to provide an intelligent detection system based on RFID, which can not only detect the wetness of diaper products, but also monitor the user's sleep in real time, thereby ensuring the user's quality of life.

[0005] An RFID-based intelligent detection system includes an RFID tag, an RFID terminal, a cloud server, a diaper product, and a mattress. The RFID tag is arranged on the diaper product and is used to collect humidity data of the diaper product. The RFID terminal includes an RFID antenna that can sense the electromagnetic signal of the RFID tag within an effective identification range. The RFID antenna is arranged on the mattress. The RFID antenna is provided with a gravity sensing module. The RFID antenna and the gravity sensing module can be communicatively connected with the cloud server. The cloud server is used to store and analyze data information received by the RFID antenna and the gravity sensing module.

[0006] In the above technical scheme, the RFID tag is flexible. When the RFID tag is set on the diaper product, the user does not feel any foreign body during use, which ensures the user's comfort. When the user wears the diaper product with the RFID tag and enters the set range between the RFID tag and the RFID antenna, the RFID antenna transmits a signal to the RFID tag, and at the same time recovers the humidity data collected by the RFID tag. The cloud server analyzes the information recovered by the RFID antenna. The nursing staff can timely and accurately understand the humidity of the diaper product by checking the cloud server, which not only greatly reduces the workload of the nursing staff, but also improves the quality of life of the user; the RFID antenna is set on the mattress. When the gravity data of the gravity sensing module set in the RFID antenna changes, the gravity sensing module transmits the collected data to the cloud server. The nursing staff can understand the user's sleep time and sleep quality through the cloud server. The utility model can not only detect the urine wetness of the diaper product, but also monitor the user's sleep in real time, ensuring the user's quality of life.

[0007] Furthermore, the RFID tag includes an RFID transceiver circuit and a chip. The RFID transceiver circuit is connected to the chip and sends the humidity data measured by the chip to the cloud server through the RFID antenna.

[0008] In the above technical solution, the working current of the RFID transceiver circuit comes from the radio frequency signal sent by the RFID antenna. When the humidity data collected by the chip reaches a preset value, the RFID transceiver circuit transmits the data to the cloud server through the RFID antenna.

[0009] Furthermore, the gravity sensing module includes a plurality of gravity sensors.

[0010] In the above technical solution, the gravity sensor is used to detect changes in gravity data. When the user rests on the mattress, the gravity sensor detects the user's sleeping state in real time and transmits the data to the cloud server so that the caregiver can check the user's sleeping condition through the cloud server.

[0011] Furthermore, two gravity sensors are provided and are respectively arranged at two ends of the RFID antenna.

[0012] In the above technical solution, since the user may turn over from time to time when sleeping, gravity sensors are arranged at both ends of the RFID antenna to accurately collect the gravity data changes of the user when sleeping.

[0013] Furthermore, the RFID terminal also includes a signal connection line and an intelligent gateway, and two ends of the signal connection line are respectively connected to the RFID antenna and the intelligent gateway.

[0014] In the above technical solution, the signal connection line is used to connect the RFID antenna and the intelligent gateway, and the RFID antenna and the gravity sensing module transmit the collected data information to the intelligent gateway through the signal connection line.

[0015] Furthermore, the intelligent gateway can be connected to the cloud server via wireless signals.

[0016] In the above technical solution, after the smart gateway receives the data information, it can communicate with the cloud server through wireless signals to exchange data, so that nursing staff can view information through the cloud server to understand the wetness of the diaper product and the user's sleep condition.

[0017] Furthermore, the intelligent gateway is provided with a power interface for plugging a power cord.

[0018] In the above technical solution, the power supply interface can provide power to the smart gateway and the RFID antenna, ensuring that the smart gateway and the RFID antenna have sufficient power and can receive data information in a timely and stable manner.

[0019] Furthermore, the cloud server is provided with a communication module, and the cloud server is connected to the smart terminal via the communication module.

[0020] In the above technical solution, in order to facilitate nursing staff to view the data information of the cloud server, the cloud server can wirelessly communicate with the smart terminal through the communication module and send the data information to the smart terminal. Nursing staff can monitor the user's condition anytime and anywhere through mobile phones, computers, bracelets, etc.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] By setting RFID tags on diaper products, the RFID antenna can receive the wetness status of the diaper product through the RFID tag. At the same time, the RFID antenna transmits the received data information to the cloud server via the gateway. Nursing staff can view the data information through the cloud server to understand the usage of diaper products and ensure the quality of life of users.

[0023] By setting a gravity sensing module in the RFID antenna and setting the RFID antenna in the mattress, when the user rests on the mattress, the gravity sensing module in the RFID antenna detects changes in gravity data. The gravity sensing module transmits the gravity data to the cloud server via the gateway. Caregivers can view data information through the cloud server to understand the user's sleep conditions.

[0028] The RFID-based intelligent detection system of the utility model will be further described in detail below in conjunction with specific embodiments and drawings. The drawings provide preferred implementations of the utility model. However, the utility model can be implemented in many different forms and is not limited to the implementations described herein.

[0029] Please refer to Figure 1 and Figure 2 In a preferred embodiment, the RFID-based intelligent detection system of the utility model includes an RFID tag 1, an RFID terminal 2, a cloud server 3, a diaper product 4, and a mattress 5. The RFID tag 1 is arranged on the diaper product 4 to collect humidity data of the diaper product 4. The RFID terminal 2 includes an RFID antenna 201 that can sense the electromagnetic signal of the RFID tag 1 within an effective identification range. The RFID antenna 201 is arranged on the mattress 5. The RFID antenna 201 is provided with a gravity sensing module 202. The RFID antenna 201 and the gravity sensing module 202 can be communicated with the cloud server 3. The cloud server 3 is used to store and analyze the data information received by the RFID antenna 201 and the gravity sensing module 202.

[0030] It can be seen from the above technical solution that since the RFID tag 1 is flexible, when the RFID tag 1 is set on the diaper product 4, the user will not feel any foreign body during use, which can ensure the comfort of the user. When the user wears the diaper product 4 with the RFID tag 1 and enters the set range between the RFID tag 1 and the RFID antenna 201, the RFID antenna 201 transmits a signal to the RFID tag 1, and at the same time recovers the humidity data collected by the RFID tag 1. The cloud server 3 analyzes the information recovered by the RFID antenna 201. The nursing staff can timely and accurately understand the humidity of the diaper product 4 by checking the cloud server 3, which not only greatly reduces the workload of the nursing staff, but also improves the quality of life of the user; the RFID antenna 201 is set on the mattress 5. When the user rests on the mattress, the gravity data of the gravity sensing module 202 set in the RFID antenna 201 changes, and the gravity sensing module 202 transmits the collected data to the cloud server 3. The nursing staff can understand the user's sleep time and sleep quality through the cloud server 3. The utility model can not only monitor the user's sleep in real time, but also detect the wetness of the diaper product 4, thereby ensuring the user's quality of life.

[0031] It should be noted that the RFID tag 1 has no requirement on the way of being set on the diaper product 4, and can be set according to actual conditions. For example, it can be printed on the diaper product 4 by printing technology, sewn on the diaper product 4 by sewing technology, or attached to the diaper product 4 by gluing method.

[0032] Specifically, the RFID tag 1 includes an RFID transceiver circuit (not shown in the drawings) and a chip (not shown in the drawings). The RFID transceiver circuit is connected to the chip. The working current of the RFID transceiver circuit comes from the radio frequency signal sent by the RFID antenna. When the humidity data collected by the chip reaches a preset value, the RFID transceiver circuit transmits the humidity data measured by the chip to the cloud server through the RFID antenna. Exemplarily, when the humidity area of ​​the RFID tag 1 reaches 80% of the total area of ​​the RFID tag 1, the RFID tag 1 is set to emit an electromagnetic wave with a frequency of 860-960MHZ, and the RFID antenna 201 provided on the mattress 5 receives the radio frequency signal and transmits the signal to the cloud server 3. The nursing staff understands the humidity of the diaper product 4 by checking the information on the cloud server 3, and replaces the diaper product 4 with a new one for the user.

[0033] Meanwhile, the gravity sensing module 202 includes a plurality of gravity sensors 2021. The gravity sensors 2021 are used to detect changes in gravity data. When the user rests on the mattress, the gravity sensors 2021 detect the user's sleeping state in real time and transmit the data to the cloud server 3 so that the nursing staff can check the user's sleeping state through the cloud server 3.

[0034] Exemplarily, there are two gravity sensors 2021, which are respectively arranged at both ends of the RFID antenna 201. Since the user may turn over from time to time when sleeping, the gravity sensors 2021 arranged at both ends of the RFID antenna 201 can accurately collect the gravity data changes of the user when sleeping. In other embodiments, the gravity sensors 2021 can also be three, six, ten or other numbers.

[0035] In addition, the RFID terminal 2 also includes a signal connection line 203 and an intelligent gateway 204, and the two ends of the signal connection line 203 are respectively connected to the RFID antenna 201 and the intelligent gateway 204. The signal connection line 203 is used to connect the RFID antenna 201 and the intelligent gateway 204, and the RFID antenna 201 and the gravity sensing module 202 transmit the collected data information to the intelligent gateway 204 through the signal connection line 203. The intelligent gateway 204 contains an RFID reader, and the RFID reader disposed inside the intelligent gateway 204 reads the data information transmitted from the RFID antenna 201 to the intelligent gateway 204.

[0036] Specifically, the smart gateway 204 can be connected to the cloud server 3 via wireless signals. After the smart gateway 204 receives the data information, it can be connected to the cloud server 3 via wireless signals to exchange data, so that the nursing staff can view the information through the cloud server 3 to understand the wetness of the diaper product 4 and the user's sleep condition. Exemplarily, the smart gateway 204 can be connected to the cloud server 3 via WiFi2.4G, WiFi5G, NBIOT, Bluetooth, etc.

[0037] At the same time, the smart gateway 204 is provided with a power interface (not shown in the drawings) for plugging in the power cord 205. The power interface can provide power to the smart gateway 204 and the RFID antenna 201, ensuring that the smart gateway 204 and the RFID antenna 201 have sufficient power and can receive data information in a timely and stable manner. In addition, the active RFID is powered by an external power supply, which increases the transmission distance and transmission speed of the RFID, greatly increasing the user's range of activities.

[0038] In order to facilitate the nursing staff to view the data information of the cloud server, the cloud server 3 is provided with a communication module (not shown in the attached figure), and the cloud server 3 is connected to the smart terminal 6 through the communication module. The cloud server 3 can communicate wirelessly with the smart terminal 6 through the communication module and send the data information to the smart terminal 6. The nursing staff can monitor the user's situation anytime and anywhere through mobile phones, computers, bracelets, etc. At the same time, an alarm module can also be set in the smart terminal 6. When the cloud server 3 receives the data information, the smart terminal 6 notifies the nursing staff to replace the new diaper product by ringing or other means.

[0039] The utility model can not only timely remind nursing staff of the humidity status of diaper products and reduce disturbance to users, but also monitor users' sleep in real time and ensure users' quality of life.
