4results about How to "Implement backup" patented technology

The hydropower station perimeter intrusion detection system comprises a radar monitoring module, a video monitoring module, a data processing module, a communication module, a control module, a power supply module, an early warning module, a data storage module and a compatible integration module. The radar monitoring module adopts laser radar equipment, and targets such as intruded foreign personnel in the surrounding environment are obtained by transmitting radar waves to the surrounding environment of the hydropower station and receiving and reflecting the radar waves. The accuracy and reliability of the hydropower station perimeter intrusion detection system are improved by adopting the Leiyu fusion technology and combining various technical means, so that the perimeter safety of the hydropower station is guaranteed. Meanwhile, the system has the advantages of real-time performance and reliability, the system can be compatibly integrated to a hydropower station electronic precaution system platform, new technical means and support are provided for hydropower station safety management, and the system has great significance in improving the safety level and accuracy of a hydropower station perimeter intrusion detection system.

The application discloses a method and device for taking 5G wireless network as a backup link under a wired ring network. The method is based on industrial data communication networking, and establishes a VXLAN tunnel between each first 5G industrial gateway and a second 5G industrial gateway by adopting a VXLAN technology, and adds all LAN ports of each first 5G industrial gateway and interfaces corresponding to the VXLAN tunnel in a same bridging group, so that each first 5G industrial gateway and the wired ring network form a large two-layer network. Based on an RSTP protocol, each first 5G industrial gateway exchanges networking with the wired ring network through the large two-layer network, and builds a backup link of the 5G wireless network and each PLC device and each DCS system, so that the 5G wireless network can be taken as the backup link under the wired ring network, and the wired ring network can be backed up by the 5G wireless network.

The present disclosure provides a repair circuit of an electrical connection structure and a control method thereof. The repair circuit of the electrical connection structure comprises an electrical connection module, M first data terminals, M second data terminals, a first control circuit module and a second control circuit module. Each first data terminal is connected to a first end of at least two electrical connection structures in one-to-one correspondence through at least two first switch units, and at least one electrical connection structure connects at least two first data terminals. Each second data terminal is connected to a second end of at least two electrical connection structures in one-to-one correspondence through at least two second switch units, and at least one electrical connection structure connects at least two second data terminals. Thus, at least two electrical connection structures are provided between each first data terminal and the corresponding second data terminal to enable data transmission, mutual backup between the electrical connection structures is achieved, and the reliability of data transmission is ensured.
