Description

Technical Field

[0001] This invention relates to the technical field of monitoring and alarm systems for abnormal physical conditions of school bus drivers, and particularly to a monitoring and alarm system for abnormal physical conditions of school bus drivers. Background Technology

[0002] A school bus is a passenger vehicle with seven or more seats that has obtained a permit to use in accordance with the "Regulations on the Safety Management of School Buses" and is used to transport students receiving compulsory education to and from school. School buses transporting primary school students should be designed and manufactured specifically for primary school students in accordance with the national standards for dedicated school buses. The school bus driver is the person in charge of driving the school bus, and the driver's good physical condition is essential for the normal operation of the school bus. The existing monitoring and alarm systems for abnormal physical conditions of school bus drivers have the following main problems.

[0003] 1. Warnings for school bus drivers mainly rely on siren devices to alert them. However, the warning sounds produced by these devices can easily affect students on the school bus, causing them to feel fear.

[0004] 2. During school bus operation, drivers may engage in unauthorized actions such as operating the vehicle with one hand, which the system cannot detect, thus posing a significant threat to the safe operation of the school bus.

[0005] 3. School bus drivers tend to adopt a single sitting posture while driving for long periods of time. The monitoring and alarm system cannot provide timely and effective reminders to school bus drivers, which leads to the use of a single driving posture, causing physical pain for school bus drivers and increasing their workload. Summary of the Invention

[0006] The purpose of this invention is to provide a monitoring and alarm system for abnormal physical conditions of school bus drivers in order to solve the above-mentioned problems.

[0007] The present invention achieves the above objectives through the following technical solutions:

[0008] A monitoring and alarm system for abnormal physical conditions of school bus drivers, characterized in that: the system uses an information processing unit as the central processor, and then controls the monitoring unit, alarm unit, and information transmission unit through the information processing unit. The system's workflow is as follows:

[0009] Procedure 1: Before driving the vehicle, the school bus driver needs to wear a wristband on his wrist. The heart rate sensor in the wristband will detect the driver's heart rate in real time. At the same time, the temperature sensor on the wristband can detect the driver's body temperature.

[0010] Step 2: While the school bus driver is driving, a high-definition camera located in front of the driver can capture the driver's face in real time, capturing the driver's facial movements at any time.

[0011] Step 3: At the same time, during driving, the driver needs to press the test button located on the steering wheel to control the timer in the system. Pressing the test button at the same time can ensure that the driver's hands are on the steering wheel and prevent the driver from operating the vehicle with one hand in violation of regulations.

[0012] Process 4: When the school bus driver is driving for a long time, the pressure sensor on the back of the seat will detect the driver's driving posture. When the pressure sensor detects pressure or no pressure, the timer in the system will start. The timer will detect the duration of the driver's single driving posture, so that the system can remind the driver in time to change the sitting posture and avoid the driver's body pain caused by sitting in a fixed posture for a long time.

[0013] Step 5: The footage captured by the high-definition camera is converted into a digital signal by an A / D converter and sent to the microprocessor along with the detection information from the wristband and the working status of the timer. The microprocessor processes the information to detect the driver's physical condition and time the duration of the driver's eye movements, thereby determining whether the driver is drowsy.

[0014] Process 6: When the driver's eye movements last longer than the preset time, the microprocessor controls the warning light to shine outwards as a warning. At the same time, in order to avoid causing students to feel scared, the vibration motor located under the seat is activated to alert the driver.

[0015] Process 7: During the monitoring of the driver's body, all monitored structures can be backed up in the system's storage module, and this stored information is sent to the terminal via a signal transmitter, so that terminal staff can monitor the driver's information at any time.

[0016] Furthermore, the wristband in process 1 is equipped with a Bluetooth module, a heart rate sensor, and a temperature sensor, which facilitates real-time monitoring and data transmission.

[0017] Furthermore, the high-definition camera in the monitoring unit of process 2 contains a three-dimensional vision sensor. The three-dimensional vision sensor in the high-definition camera can obtain more than 300,000 three-dimensional point information in 30 milliseconds to construct a real three-dimensional scene.

[0018] Furthermore, in process 3, the test buttons are located on both sides of the steering wheel for easy use by staff, and they need to be pressed simultaneously to start the timer.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. This invention uses warning lights and a vibration motor to alert school bus drivers, avoiding the generation of sound during the alert process and preventing any impact on students, thereby preventing students from feeling afraid.

[0021] 2. This invention enables school bus drivers to press the test button with both hands simultaneously within a specific time period to control the timer in the system. By pressing the test button simultaneously, the driver's hands can be kept on the steering wheel, avoiding the driver's violation of operating the vehicle with one hand and preventing potential safety hazards.

[0022] 3. In this invention, when a school bus driver is driving for a long time, a pressure sensor on the back of the seat detects the driver's driving posture. When the pressure sensor detects pressure or no pressure, it will trigger a timer in the system. The timer detects the duration of the driver's single driving posture, so that the system can promptly remind the driver to change his sitting posture, avoid the driver's body pain caused by prolonged fixed sitting posture, and reduce the driver's workload.
