GPS positioning system for coach. What functions can be implemented now?

Design principle of GPS monitoring system for long-distance bus in Shenzhen Sanlian Industrial Co., Ltd.

When designing the technical implementation scheme of the system, we followed the following principles:

● Everything is for safety. "Safety reminder, safety monitoring" is the goal of our product design.

● Safety reminders include: speeding reminder, dangerous section reminder and fatigue driving reminder.

● Safety monitoring includes: overspeed monitoring, overload image monitoring, fatigue driving reminder, shouting reminder, etc.

● Common standard functions: remote setting, monitoring, calling, scheduling, alarm, etc.

2. 1. 1 Economy of long-distance bus GPS monitoring system

The design of long-distance bus GPS monitoring system reduces the cost as much as possible under the optimal performance and pursues the maximization of cost performance. All software systems are independently developed, which facilitates long-term cooperation and ensures the economy of the software system.

2.2. 1 1 image monitoring

● Car monitoring: The camera is aimed at the car, which can monitor whether the car is safe and the weather conditions.

● Road condition monitoring: the camera is aimed at the road condition in front of the windshield to judge whether there is traffic jam or road condition.

● Driver monitoring: aim the camera at the cab to check whether the driver on duty and driving operation are illegal.

● Support up to 4 cameras.

2.3 composition of long-distance bus GPS monitoring system

The monitoring center is the "nerve center" of the whole long-distance bus GPS monitoring system, which centrally realizes information services such as monitoring, scheduling, receiving/processing alarm, image processing and so on, and coordinates and manages the software and hardware of the whole long-distance bus GPS monitoring system.

2.4 Vehicle Terminal Functions

Responsible for data transmission between vehicle terminal and monitoring center. This part is mainly GPRS/CDMA public data network. As long as GSM or CDMA can cover the area, the system can run stably. Common functions include the following aspects:

Vehicle positioning: timing continuous positioning, speed measurement, moving direction, etc.

Monitoring alarm: speeding, fatigue driving, unloading, unexpected long-term parking, etc.

Remote monitoring: used for on-site judgment after robbery alarm.

Fuel cut-off and power cut-off: used for remote car locking in case of emergency.

SOS Emergency Help: When the driver feels dangerous, manually trigger the highest level alarm.

Car phone: hands-free call, handle call, display call (external headset).

Text scheduling: external scheduling screen, handle, etc.

Voice broadcast: External voice broadcast with speakers.

Image transmission: 1-4 camera with night vision.

User-defined alarm: users can connect various detection switches as needed, and support triggering cameras to take pictures.

Chapter 3 Introduction of Monitoring Center System

● Monitor violation alarms.

● Overspeed alarm: when the speed threshold set by the company is exceeded, an alarm is uploaded and reported.

● Fence alarm: alarm when the vehicle exceeds the specified driving range;

● Emergency alarm: When the owner is in danger, press the alarm switch to give an alarm, and the center must intervene manually to cancel.

● User-defined alarm: 1-2 user-defined alarms are supported. If the door is opened due to an alarm, the vehicle should be connected to the door switch.

● Power failure alarm: battery removal or equipment power failure alarm must be relieved by manual intervention.

3. 1 Vehicle position tracking and multi-vehicle simultaneous tracking

● Real-time positioning: roll-call positioning to query the current time and position of the vehicle;
