Car safety warning recorder and its initial setting, warning and PDA reading method

Abstract

The automobile safety warning recorder and its initial setting, warning and PDA interpretation method of the present invention are suitable for installation and use on motor vehicles. The structure has a black box host computer and a handheld computer PDA with an infrared interface. The black box host includes a central processing unit CPU, a memory, a driving data signal interface, an infrared interface, a serial interface, a voice output circuit, and a clock circuit. The initial setting, warning and PDA interpretation methods of the car safety warning recorder adopt the speed self-adaptive technology. By sampling a certain actual speed stipulated by the car, the speed coefficient of the car is obtained after automatic calculation, which can be used to determine the known or unknown speed. The speed coefficient of the vehicle is initially set; the black box monitors the driving speed in real time. When the driving speed of the car exceeds the specified value, the black box automatically sends out voice warnings for each speed segment to remind the driver not to drive over the speed limit; The palmtop computer PDA is used as the data acquisition display.

Description

technical field [0001] The present invention is an instrument for real-time monitoring of automobile driving data, voice speed warning and driving data recording, an automobile safety warning recorder (automobile black box) and its initial setting, language warning and PDA interpretation method, which are suitable for installation on motor vehicles use. Background technique [0002] The main function of all kinds of black boxes installed on motor vehicles is to record driving data such as driving speed. The system composition usually includes black box host and data collector (card) and other supporting devices. Generally, special data integrator or IC card is used for black box Initially set and collect the data recorded by the black box, its disadvantages are: [0003] 1. When the black box is installed, the speed coefficient of the black box host should be initially set. The speed coefficients of different models are different. If it is a new model with an unknown speed ...

AI Technical Summary

Problems solved by technology

[0003] 1. When the black box is installed, the speed coefficient of the black box host should be initially set. The speed coefficients of different models are different. If it is a new model with an unknown speed coefficient, the initial setting must be completed after repeated sports car tests, so that The installation process of the black box is very cumbersome

[0004] 2. The special data collector is large in size and simple in function. It needs to connect cables when collecting data. The IC card cannot interpret the data content on site. The contact card holder is easily polluted and causes poor contact.

[0005] 3. The general black box function focuses on data recording. There is no warning function or there is only an overspeed warning light or buzzer warning for a fixed speed, and the ability to prevent accidents is weak.
