With the rapid development of UAV technology in the last decade, UAV will play an increasingly important role in information acquisition and unmanned combat. It is difficult for one UAV to meet the needs of complex tasks. The application Application mode of UAV formation coordination is becoming a new cooperative combat mode at home and abroad. When the UAV cluster works together, information exchange and management will be required and data link support is needed.The adaptive broadband wireless data link network is the key link for UAV cluster operations. EVB Mobile Wireless Intelligent Internet System adopts advanced broadband mobile self-organizing network as its core network technology. It has obvious technical characteristics such as automatic network organization, automatic healing, high bandwidth, support for high-speed mobile and so on. At the same time, it has small size, low power consumption, fast deployment, strong anti-interference ability and network expansion in app...

In comprehensive operations such as emergency rescue and disaster relief, counter-terrorism breakthrough, emergency response, large-scale activities and cross-regional linkage, multi-department joint service linkage and multi-unit cooperation are needed to achieve resource sharing and unified command. Interconnection of on-site communication systems is the key. Quickly establish on-site unified communication command system, which can not only utilize existing network communication resources, public network voice intercommunication, wireless command incompatibility with different frequencies and standards,front-end video acquisition and monitoring.A new command mode that realizes vertical flat command and horizontal and inter-departmental linkage and cooperation. Our Solution: All wireless nodes in the EVB broadband wireless networking system are automatically networked. Each node can be used as an access point and a receiving point. It is especially suitable for public security, emerge...

The oilfield is located in remote and offshore areas, and production management is more difficult. Usually it is necessary to reduce the difficulty of on-site management by means of huge gathering pipelines and increased oil production platforms.The production parameters of oil well can not be obtained normally due to weather changes and transportation tools.Seriously affecting the automatic management of oil well. Using wireless IP sensor network technology, various well field sensors and instrumentation data such as load sensors, angular displacement sensors (or pulse generators), monitors, electrical parameters sensors, etc., can be collected into remote RTU, and then transmitted to the production center through other communication methods. Our  solution: Advantage: Reduce maintenance by ensuring high reliability Network coverage in difficult terrain and wide space area Withstand harsh weather conditions Reduce the cost of large-area deployment by eliminating cabling an...

The oil storage and transportation system consists of oil tank,manifold,pumping station,oil pipeline system and other dispersed facilities.The working status and data of various facilities of the whole system are directly related to the stable and safe operation of the oil pipeline.At present, most of the work is regularly checked every day for equipment operation,measure and statistic the data of oil production. Since the oil tanks and distribution of oil pipelines is mostly distributed from tens to hundreds of square kilometers.This way will inevitably aggravate the labor intensity of workers, and affect the real-time accuracy of equipment monitoring and oil production data.So it is very important to realize automation and information management operation. Based on EVB and ad hoc network technology, cloud platform and big data analysis, the oil transportation storage monitoring system realizes automatic, real-time, high efficiency and low cost management by monitoring the...

Under the new international situation, maintaining the security and integrity of territorial boundaries and waters has become increasingly important and complex. In order to strengthen the ability of real-time monitoring and investigation and evidence collection, and improve the overall level of law enforcement vessels, wireless communication as a key means of communication is essential for the efficiency of law enforcement personnel in handling incidents. Existing conventional wireless communication faces some problems and limitations in the application, mainly reflected in the following aspects: Limited bandwidth: only transmit voice, only solve the "listening to see", but "can't see", "can't touch" and "can't control"; Limited coverage: there is no signal in some waters or sea areas, and the cost of large-scale coverage signals is huge; Poor interoperability: There are various types of equipment between departments, which cannot b...
