Description

Technical Field

[0001] This utility model relates to a monitoring instrument, and more particularly to a smart monitoring instrument for diapers. Background Technology

[0002] In daily life, newborn babies, toddlers who have just learned to stand and walk, bedridden elderly people, and elderly people with urinary incontinence all use diapers because existing diapers have the functions of being waterproof, urine-proof, and preventing leakage to the other side.

[0003] Among the many people who use diapers, elderly people who can express themselves and feel their surroundings will promptly inform their caregivers after urinating so that the diapers can be changed quickly to prevent prolonged immersion in urine and subsequent skin infections. However, for newborns who cannot speak and elderly people who have lost their senses, how can caregivers be informed immediately that the person under their care has urinated so that timely intervention can be provided? This is a technical challenge that urgently needs to be addressed in this industry. Summary of the Invention

[0004] In view of the problems existing in the above-mentioned technology, this utility model provides a smart diaper monitor that can transmit the information of the ward urinating to the guardian in the first instance so that the diaper can be changed in time.

[0006] The detection module is connected to the main control module. It receives the raw signals from the sensor through the AO (Analog Output) interface and outputs high and low level signals through the DO interface.

[0007] The main control module, as the control center of the entire system, coordinates the work of various modules to ensure that the entire system can operate efficiently and stably. It is responsible for receiving input signals from button operations and sensor data, processing and making decisions on this information according to the preset program, and issuing control commands.

[0008] The sensor module is responsible for collecting various information about the environment or diapers. One end of the sensor module is connected to a probe, and the other end is connected to the detection module. The sensor module receives the signals detected by the probe from the diapers and transmits the signals to the main control module. The main control module then transmits these signals to the detection module for analysis and processing to obtain the detection results.

[0009] The battery management module is responsible for monitoring the battery's charge and status. Through its connection with the battery, power supply, and control signals, it enables precise control of the charging process and ensures the stable operation of the battery during constant current charging, constant voltage charging, and charging termination.

[0010] The 4G communication module is responsible for communicating with external networks to achieve remote data transmission, enabling the system to send detection data to a remote server in real time or receive instructions and control signals from a remote location.

[0011] The indicator light module is used to display the system's operating status, such as whether it is powered on or communicating, so that users can intuitively understand the system's operation.

[0012] The button module provides an entry point for users to interact with the system. Users can input commands or query the system status by pressing the buttons.

[0013] Furthermore, the 4G communication module includes a SIM card module, a U1A communication module, a U1B communication module, a U1C communication module, and a U1D communication module. The U1A communication module and U1B are combined to achieve signal differential amplification. The U1C communication module serves as a UART / USB signal conversion node, connecting the main control module and external devices, and integrates USB communication protocol parsing functions. The U1D communication module is used to implement interface protocol conversion such as UART to USB, and integrates level conversion functions to ensure reliable communication between devices in different voltage domains. The SIM card module is connected to the U1A communication module.

[0016] Furthermore, the switching transistors Q2 and Q3 are connected between the main control module and the U1A communication module as level converters to ensure that the debugging signal is transmitted stably and accurately to the main control module.

[0017] Furthermore, the field-effect transistor Q6 is connected to the battery management module and, as a field-effect transistor, is used for signal amplification, switching control, or level conversion.

[0018] Furthermore, the main body of the monitoring device includes a top shell, a bottom shell, an upper clamping plate, a lower clamping plate, a hinge shaft, and a spring. The top shell and the upper clamping plate are fastened together to form a first cavity, and the main board is disposed in the first cavity.

A hinge part is provided at the bottom of the upper clamping plate, and a hinge interface is provided through the upper part of the lower clamping plate. The bottom of the hinge part passes through the hinge interface and is disposed in the second cavity. The hinge shaft is disposed at the bottom of the hinge part, and a spring is provided on the hinge shaft. The spring is a torsion spring, one end of which is fixed to the bottom of the hinge part, and the other end of which is fixed to the lower clamping plate. By setting the spring, the upper clamping plate and the lower clamping plate tend to move closer to each other to form a clamping opening for holding diapers. The clamping opening is located between the upper clamping plate and the lower clamping plate at the end away from the spring.

[0019] Furthermore, the probe is mounted on the motherboard, with its end furthest from the motherboard passing through the upper clamp and positioned within the clamping opening.

[0020] Furthermore, a sensor patch is detachably provided inside the clamp, one end of which is electrically connected to the probe in contact, and the other end is located inside the diaper; the sensor patch is connected to the sensor module via the probe to transmit the sensing signal to the sensor module.

[0021] The beneficial effects of this utility model are: this monitoring device can promptly detect the information of the ward urinating, which not only avoids the ward being soaked in urine for a long time and protects the ward's health, but also provides convenience for the caregiver to carry out convenient and hygienic care work, reduces the care burden, and improves care efficiency.
