15km lr wifi module high broadband port portal control signal wireless transmission of unmanned ship, unmanned ship is an automatic surface robot, can sail on the water without remote control, with the help of precise satellite positioning and self-sensing. Today, many countries have begun to develop unmanned ships. Some shipping magnates even optimistically predict that mature "ghost ship" technology will rewrite the face of global ocean transportation, perhaps within a few decades. In this environment, wireless signal transmission and control are the key solutions for the development of unmanned ships.
Site situation: The customer needs to transform the original speedboat into an unmanned ship, with 6 cameras and industrial control system installed on the ship. Each camera needs 4M code stream and the bandwidth of the control system needs 2M, which adds up to 26M bandwidth. Unmanned ship technology requires a high delay, which is within 200 milliseconds, and the longest distance of unmanned ship is 5km. This project needs to customize a special wireless transmission scheme 15km lr wifi module CV5200 for wireless transmission for signal transmission.
Scheme design: A 360-degree omnidirectional antenna of 15km lr wifi module is installed on the unmanned ship, so that the ship can transmit video signals and control signals to the shore receiving end, which is equipped with a large-angle antenna. All video signals are received through the control center, and the direction of the ship is controlled remotely. The video images of the control center are transmitted to the general command center in the background through the network. The general command center can see the ship's motion status and video images remotely.
The wireless video surveillance transmission case of port door machine, the process of global economic integration and the continuous integration of the international market make the port terminal become a large freight turnover center, with hundreds of large cargo ships and thousands of large containers every day. In such an extremely complex environment, how to ensure the safety of transportation, production and cargo has become the most concerned issue for port terminal management personnel. The rapid development of wireless transmission technology and image compression processing technology provides efficient, feasible and cheap solutions for port trade to realize local and remote monitoring, image monitoring and network alarm system. In view of the characteristics of ports, traditional monitoring methods are difficult to meet the actual requirements. 15km lr wifi module remote wireless transmission system adopts wireless network as transmission mode, no manual wiring, convenient installation, affordable, can better meet the needs of port monitoring
I. Project requirements:
1. Real-time observation of the work progress and situation of the portal crane. Relevant person in charge can observe the operation situation through the 15km lr wifi module wireless transmission system without the need to be present.
2. Multi-view, ensure the safety of door crane operators and their environment, through 15km lr wifi module wireless transmission of the station door crane driver's vision, avoid sight dead corners, improve the safety of operation.
3. Work records can be used as strong evidence of accident records and events.
Ii. Program Introduction:
There are 4 door machines on site, and each door machine has 3 image signals that need to be transmitted to the central control room. The distance between door engine and central control room is 1-2KM, visual distance. After understanding the situation of the site, the wireless bridge is used for one-to-four transmission. After each portal machine summarizes 3 videos through the switch, 4 video WSV is used as the launch; 1 central control room; CV acts as the receiver and receives the signal for access through the NVR. The whole link adopts 100 megabit industrial grade wireless network bridge to ensure stable and reliable data transmission.
Iii. Project Effect:
1.15km lr wifi module system integrates wireless transmission, video monitoring and SMS notification, realizing the integration of hardware and software with a high degree of automation;
2. Strong anti-interference ability, to ensure the stability of equipment and system, data integrity, data reliability;
3.15km lr wifi module is safe and reliable; Wireless transmission mode, no wiring, convenient expansion, easy management.
