Car Accidents

Based on data from the Indonesian Traffic Corps by September 2019, the number of car accidents was dominated by rear-hit crashes with 6,966 accidents. Most of these accidents occurred during car convoys. It needs a car-to-car communication to increase driver awareness. One of the technologies that can be applied is Visible Light Communication (VLC) and infrared communication. The transmitted data are the vehicle speed data, throttle position, and brake stepping indicator. The data are obtained by reading the Engine Control Unit (ECU) in the car. The data are packaged from the three data and sent to other cars at day and night using VLC and infrared communication. The experimental results show that in a communication system that uses VLC, data can be exchanged between cars during the day up to 2 meters and at night up to 11 meters. Otherwise, in infrared communication, vehicles can communicate during the day up to 2 meters and at night up to 0.7 meter. The test was also carried out with some conditions such as rain, smoke, passers, and other vehicle lights.

Receiver Architecture

A high performance and low power architecture is devised for a 4 Mbps infrared wireless communication system dedicated to mobile computing. In this architecture, 4PPM (4-Pulse Position Modulation) infrared signals detected by an infrared receiver are digitized into TTL interface level pulses, and the digitized pulses are demodulated by a 1-bit digital demodulator. To extend the range of the link length, a 4PPM demodulator is synthesized to implement a demodulation algorithm which is constructed so as to accommodate the output tolerance of the infrared receiver. A part of the experimental results shows that the proposed 4 Mbps infrared communication system can achieve an error free link in the range of 0–140 cm at power consumption of 245 mW and 65 mW for transmitting and receiving, respectively. The communication controller is integrated in a 0.6 μm CMOS standard-cell chip which contains 10,015 transistors on a 12 mm2 die.

Train-Ground communication system is mainly used to complete the communication between the train and the ground, the data which is produced by security computer system is vital to safe operation. The paper focus on the reliability and security technologies of embedded computer system and evaluates the reliability of TMR (Triple Modular Redundancy), which is based on the existing research of security computer and aimed on the equipment of CBTC Train-Ground communication system. The technology of CBTC Train-Ground communication is studied and the structure of the TMR for Train-Ground communication system is designed in the paper. Furthermore, the fault - safety circuits，electromagnetic compatibility technology and rail traffic-related safety standards are analyzed. Finally, the Train-Ground infrared communication security transponder system based TMR is applied to Shanghai People's Square Line 8 subway train’s double-door control system.

Wireless Data Communication

As a kind of wireless communication, Infrared wireless data communication has been developing rapidly and has been widely used in the close wireless data communication. In this paper, there is the design and achievement of infrared communication system, which has realized the short distance transmission of voice and digital signal (temperature signal). The modem part of the system is implemented by the phase locked circuit composed of LM567. At the same time, with the single chip processor as the core, the temperature information which has been encoded is added to the audio signal and then to be transmitted to the receiver to be decoded to restore the temperature information. After the test of implementation, this system can transmit the speech signal and digital signal directly and the voice signal received has no obvious distortion. This system is simple in making and has a good application prospect.
