Problems solved by technology

The high-brightness light flashes regularly, giving the pilot a very significant dynamic prompt, so as to guide the aircraft to find the center line of the airport, approach and land smoothly. The equipment currently on the market has poor anti-interference ability, high bit error rate, and no error correction. Error retransmission mechanism; an error in a certain node may cause the entire network to be paralyzed, etc.
There are even some devices that are completely designed with analog circuits and do not have networking functions, which obviously cannot meet the needs of airport informatization and modernization.

Embodiment Construction

[0014] Such as figure 1 As shown, the entire network is composed of a host node and several sub-light box nodes. The indoor host node is composed of the No. 0 node communication module and the control host. The outdoor multiple sub-light box nodes are composed of its communication module, control device and flash working device. All nodes are connected in parallel on the KVV armored cable through the CAN drive interface.

[0015] The CAN bus uses differential voltage to transmit signals. The KVV cable is composed of two core wires, which are respectively used as CAN high voltage (CAN_H) and low voltage (CAN_L) lines. Terminal matching resistors are used at both ends of the KVV cable to connect line 1 and line 2. Lines are connected, such as figure 2 As shown, the indoor host is connected in parallel at one end of the KVV cable, and the outdoor sub-light box nodes are evenly connected in parallel at the other end of the cable at a distance of 30 meters, thus forming a complet...

Abstract

This invention relates to a system for controlling and monitoring visual landing lights based on CAN bus, which is a distance digital signal communication system for airport visual landing lights disclosing an indoor No.0 node including a CPU, a CAN bus module, an input module, an echo module, a serial communication module and a monitor module, several outdoor nodes of branch lamp boxes are also disclosed, all modes are parallel hung on KVV armored cable via CAN drive interface.

Description

technical field [0001] The invention relates to a long-distance digital signal communication system guided by visual landing light at an airport, which is a control network based on CAN bus. Background technique [0002] In recent years, with the continuous expansion of the city, the light pollution near the airport has become increasingly serious, especially at night when the weather is complex, it is difficult for pilots to find the center line of the airport when landing. The airport visual landing light guidance equipment is a flashing device used in the approach lighting system. By controlling the flashing light, it acts as a visual device to display the extension line of the center of the airport runway. The high-brightness light flashes regularly, giving the pilot a very significant dynamic prompt, so as to guide the aircraft to find the center line of the airport, approach and land smoothly. The equipment currently on the market has poor anti-interference ability, hi...
