To reduce the traffic accidents when backing and parking, we develop a sort of vehicle reverse sensor alarming system based on the CAN bus. The system can be divided into the range acquisition module, the system control module, the bus node controller and the display alarm module. The range acquisition subsystem adopts the ultrasonic technology to measure the distance between the vehicle and the obstacle...
In order to reduce the vehicle rear collisions and the damage degrees on passengers, we adopt the dot matrix display technology and the vehicle high positioned brake reminder technology based on CAN bus. The designed high positioned brake reminder system is composed by the nodes based on CAN bus. The first node is the sensor data acquisition node based on SCM. The brake position sensor in the node...
The real-time detection of pulse signal has important meaning for the early discovering and treatment of heart diseases. A novel pulse signal-recording instrument based on system-on-chip and separated universal serial bus (USB) interface chip is developed. The hardware system and application software are designed and the whole principle of various details in the device is described. The system selects...
The image acquisition system is one of indispensable parts in various kinds of digital image application system. In this article, we developed a sort of video camera compact image acquisition and processing system based on AVR single chip microcomputer. The system utilises AVR single chip microcomputer ATmega16 with low power consumption and high performance as the data processing main control unit...
The pulse signal is a sort of important human physiological signal. A pulse signal acquisition system based on the virtual instrument technology is developed. The system is composed of two parts, i.e. the data acquisition equipment taking single chip microcomputer (SCM) as the core hardware and the data processing system based on LabView software on the computer. The integrated pulse sensor based...
