Port terminal gantry crane / airport long-distance wireless module transmission scheme, our company has designed many wireless transmission schemes for ports and terminals, and the common one is undoubtedly the monitoring scheme of gantry cranes (usually called gantry cranes). The gantry crane is a common mechanical equipment in port terminals, mainly used to transport ships to load and unload goods. In fact, portal cranes and tower cranes have a lot in common. They work in complex environments and are inconvenient for wiring. Whether it is a gantry crane or a tower crane, when a safety monitoring system needs to be used, generally only the wireless transmission system can be considered.
The practicality of the remote wireless module wireless transmission system of the door operator:
1. Observe the working progress and situation of the door operator in real time, and the relevant person in charge can observe the operation situation through the wireless transmission system without being physically present.
2. Multi-viewing angles ensure the safety of the door operator and its environment. The long-distance wireless module wirelessly transmits the field of vision of the door operator to avoid blind spots and improve operational safety.
3. Work records can be used as accident records and become strong evidence of events.
Long-distance wireless module wireless transmission application:
1. Wireless transmission technology
Unlike tower cranes, gantry cranes often require mobile operation, so traditional wired monitoring systems cannot be used, wireless transmission equipment is used, larger transmission angles are adjusted to complete the task, or mobile transmission equipment is used. Therefore, port terminal people usually choose wireless transmission system.
2. Normal operation in harsh environment
Most wireless transmissions are industrial-grade equipment, which can be used for normal operation in severe weather such as wind, snow, rain, and fog, and can continue to operate normally even in the port's windy, high humidity, and high acid-base corrosive environments all year round.
3. Shared network platform
The long-distance wireless module line transmission system can not only record video information, but also store video images on the Internet. When various departments need to watch the video recording, they only need to log in to the Internet to access it, and Wu Yan rushes to the scene of the monitoring center in person.
Airport long-distance wireless module wireless transmission scheme, aircraft are prone to safety accidents during take-off and landing. If there is no reasonable scheduling measures, it is easy to cause runway intrusion and runway protection accidents. Aircraft take-off and landing security monitoring allows take-off and landing controllers to monitor airport activities well. Install surveillance cameras in relevant areas. When the runway is occupied or it is inconvenient to land, the alarm will be issued in advance, so that the pilot can take relevant measures in advance to reduce the risk of the plane overrunning the runway. Due to the large area of the airport and the scattered distribution of surveillance cameras, the construction wiring is very inconvenient. Therefore, the system is usually realized by wireless transmission of long-distance wireless modules.
Features of long-distance wireless module:
2.4G frequency band work, strong anti-interference ability
Using POE power supply, the construction is simple and convenient
Built-in 17dBi antenna, high receiving sensitivity
Support point-to-point and point-to-point wireless transmission
Long transmission distance up to 15 kilometers
20 channels do not interfere with each other, stable transmission
Wireless transmission system analysis:
According to needs, install high-definition surveillance cameras on both sides of the runway to monitor whether there is any accidental intrusion around the runway. This program is a pilot program. First, four cameras with long-distance wireless modules are installed. The monitoring center is located in the nearby control room, within 3KM from the monitoring point.
Industrial-grade wireless transmission equipment is installed in the monitoring centers of four monitoring points as wireless transmitters, and long-distance digital wireless bridge-range digital long-distance wireless modules are used for one-to-two reception. Send 4-channel images 1 to 2 to the dispatching room through wireless transmission equipment. The wireless transmission equipment summarizes all the data through the switch, and then connects to the NVR with the network cable and performs storage and real-time monitoring with the computer.
