Brief introduction to the use of antenna tracking system in wireless monitoring

In wireless monitoring, the antenna is a very important part. The antenna is an indispensable accessory. The signal generated by the wireless monitoring device is transmitted through the antenna. The antenna is used to transmit or receive electromagnetic waves. In wireless monitoring we use high-gain antennas to transmit signals. The so-called high-gain antenna is relatively narrow in the direction of radiation, and the radiation in some directions is concentrated, so the energy is concentrated in some directions, so it is reflected in the gain in some directions.

In the wireless monitoring system, the transmission of the directional antenna must align the transmitting end with the receiving end antenna to transmit the signal, while the omnidirectional antenna can transmit the signal in all directions, but the gain of the antenna is not as large as that of the directional antenna, then the signal is transmitted. The omnidirectional antenna has no directional antenna to transmit far. However, in some special circumstances, such as on-board, on-board and other front-end mobile environments, it is necessary to use omnidirectional antennas to transmit signals to meet the transmission conditions, but the transmission distance of omnidirectional antennas often fails to meet our requirements. In response to the above situation, Shenzhen Lai'an technology technicians developed an antenna tracking system in more than a year.

The antenna tracking system usually consists of a tuner, an antenna feed, and an automatic turntable, as well as a signal feedback and control circuitry to accurately align the target orientation for good communication performance. Achieve long-distance tracking and shift the corners with the target. It is usually applied to ground stations and between satellites to realize real-time and tracking communication.

Shenzhen Lai'an Technology has developed a LA-680MBC mobile communication system by using the antenna tracking system combined with our wireless monitoring equipment. The equipment is based on the TCP/IP protocol for mobile devices such as cars and ships. Video, data, voice, and has a high bandwidth advantage. The antenna tracking system uses a complex algorithm such as a GPS electronic compass accelerator, and a high-gain fixed-angle antenna is installed in the system carrier, and the fixed receiving end is accurately and automatically tracked during the movement, thereby improving the transmission distance and the effective bandwidth. The server is not limited by frequency, keeps the high-speed link between the fixed end and the mobile terminal, ensures that the mobile terminal accesses the Internet and other systems, satisfies the check email, performs multi-party VoIP and more functions.

The moving pass is a pan/tilt with an internal antenna (directional high gain) and can track the other end of the signal (the antenna and bridge board hardware are selected for the specific application environment). The antenna is configured with a corresponding gain directional antenna according to the communication distance. The hardware configuration of the bridge motherboard corresponds to the hardware of the shore-based/fixed-end motherboard bridge. The system has flexible and maneuvering rotation characteristics, which ensures fast and real-time static and dynamic transmission of data, automatic recapture time is short, and communication can be quickly resumed after exiting the communication blind zone;

The moving medium is suitable for ferry transmission, ocean operation, maritime unmanned ships, drones and other data transmission. Especially for in-vehicle and shipborne wireless monitoring data. The system uses advanced technology, no matter in the transmission distance or bandwidth rate, the mobile device has been greatly improved. It is the perfect solution for all kinds of ships to search for broadband in offshore waters and reduce the cost of traffic.
