Embodiment 1

[0018] Example 1: figure 2 is the circuit used in this device. Its core chip is a Bluetooth MP3 chip in a 48pin LQFP package. Its periphery is only a few power filter capacitors, a crystal oscillator, and a Bluetooth antenna loop. U1 is the core chip; capacitor C2, capacitor C3, capacitor C4, capacitor C11, capacitor C7, capacitor C8, and capacitor C9 are power filter capacitors; capacitor C5, capacitor C6, and crystal oscillator X1 are oscillator loops that provide clock signals for the core chip; Button RST1 and resistor R3 are reset circuits; capacitors C1, L1 and L2 are Bluetooth antenna loops; capacitor C12 and capacitor C14 are audio DC blocking capacitors.

Embodiment 2

[0019] Embodiment 2: increase the interface part circuit, such as image 3 As shown, this part includes power supply circuit CN2; CN1 for communicating with the motherboard; USB1 for upgrading and playing USB disk. CN2 provides 12V power supply for this part of the circuit; it is used for power amplifier circuit and 5V power supply circuit. CN1 provides communication function for this part of the circuit, communicates with the motherboard through the serial port, and the motherboard controls the playback content of this part of the circuit; USB1 provides an interface for the software upgrade of this part of the circuit; at the same time, insert an audio MP3 disk to play music signals.

Abstract

The invention discloses a Bluetooth voice broadcast system for a smart nursing device. The Bluetooth voice broadcast system comprises a power source and power amplifier circuit, and a Bluetooth voiceplaying circuit. The power source and power amplifier circuit comprise a chip U2 and a transistor Q1. The Bluetooth voice playing circuit comprises a single chip microcomputer U1. The pin 16 of the chip U2 is connected to the pin 34 of the single chip microcomputer U1 through a capacitor C12. The pin 4 of the chip U2 is connected to the pin 33 of the single chip microcomputer U1 through a capacitor C14. The Bluetooth voice broadcast system for the smart nursing device is provided with a Bluetooth broadcast system on the basis of a conventional nursing device, and can achieve voice broadcast and voice reminding functions.

Description

technical field [0001] The invention relates to a broadcast system, in particular to a bluetooth voice broadcast system for intelligent nursing equipment. Background technique [0002] Intelligent nursing equipment is a kind of nursing equipment for defecation and defecation of patients with limited mobility. It usually includes a toilet and a host connected to the toilet. The toilet is used to be installed on the patient's bed for collecting the patient's At the same time, it can also help people take a bath and wash their hair, and the host uses negative pressure suction to send the patient's urine and stool to the dirt box located in the host, so as to solve the problems of such patients' defecation and body cleaning. . [0003] Most of the existing intelligent nursing equipment does not have the function of voice broadcast, and its scope of application is relatively narrow. Contents of the invention [0004] The purpose of the present invention is to provide a blueto...
