Further, the Lora sending module is a wireless sending module with SX1278 as a core.

Further, the MCU employs STM32F1 series.

Further, the receiving module adopts an SX1278 model series chip.

Compared with the prior art, the invention has the advantages that: the school bus seat mainly solves the problem that when a school bus runs, an infant is ensured to be seated on the school bus seat, and a driver is reminded to pay necessary attention once the school bus leaves the school bus seat.

Detailed Description

The invention is further described with reference to the following figures and detailed description.

As shown in figure 1, the invention mainly comprises a sending end and a receiving end, wherein the sending end is used for detecting and sending the state on a seat, and the receiving end is used for receiving and sending the message of the sending end and displaying the message on a panel through a light-emitting diode and is provided with a prompt tone and a plurality of keys.

The transmitting end is composed of a power supply, an MCU, a detection unit and a Lora transmitting module. The power supply is composed of a backup battery and a working power supply.

The invention provides a charging module for a backup battery, and a working power supply provides stable power supply for the whole machine.

The MCU is the currently popular STM32F1 series and is used for detecting in real time and processing the state of the seat;

the detection unit consists of a common key circuit and is connected with the MCU, when the infant sits down, the interior of the circuit is conducted, and when the infant leaves the seat, the interior of the circuit is disconnected;

the Lora module is a wireless sending module with SX1278 as a core, is provided with a local address of a client and sends the state to the other end, so that the trouble of wiring in a vehicle is saved;

the receiving end comprises a power supply, an MCU, a display unit, a receiving module, a buzzer, a key unit and the like.

The power supply provides the working power supply of the whole machine, and the MCU is mainly used for processing the received information and displaying the state of the seat.

The display unit is composed of a plurality of light emitting diodes and used for displaying the state of each seat, the light emitting diodes are off when the seats are normal, the light emitting diodes are on when the seats are abnormal, each seat corresponds to one light emitting diode one by one, and the corresponding seat number is marked for reminding a driver.
