During detection, a bridge and tunnel do not need to be closed, and traffic is not affected. There need only be several UWB base stations and charging and data receiving devices arranged on the bridge-tunnel structure, and by means of UWB positioning, laser SLAM and IMU navigation technologies, different working areas may be divided in the bridge and the tunnel, and a plurality of wall-climbing robots are supported to operate simultaneously. Automatic path planning and automatic obstacle avoidance may be achieved, and unattended regular automatic inspection may be implemented.

Abstract: A pressurized gas piston spraying rotary engine system having two work applications, which acts as a new transformation of the application mode of pressurized gas power supply; in terms of the form of applying pressurized gas, one mode of input by means of pressure or release functions is changed. By changing the application structure, the pressurized gas achieves two work applications after one input, so that a piston changes to concentric rotation under the pressure mode without stopping all running work methods. The pressurized gas introduced from the piston works by means of pressure and then a second turbine release and work application is performed in a storage mode, thereby changing the state of low thermal efficiency in pressurized gas applications, so as to achieve and improve truly energy-efficient energy application technology. The presentengine system defines and determines a new use method for pressurized gas in the application field in a scientific and practical sense, thus truly achieving the full utilization of energy, and realizing a more efficient application mode for pressurized gas internal energy.

Abstract: La présente invention concerne un procédé et un système de localisation de défaut et de récupération de défaut destinés à un réseau de distribution de courant continu moyenne tension. Le réseau de distribution de courant continu moyenne tension utilise un convertisseur en pont complet. Un réacteur de limitation de courant est disposé au niveau d'une extrémité de départ de la ligne de distribution de courant continu à moyenne tension ; un commutateur de charge et un dispositif de protection contre le courant continu sont prévus au niveau de chaque partie segmentée de la ligne ; un réseau de communication est conçu pour mettre en œuvre une communication entre des protections contre le courant continu. Lorsqu'un défaut se produit dans le réseau de distribution de courant continu moyenne tension, le convertisseur en pont complet limite le courant de défaut à zéro ; lorsque le courant de défaut dépasse une valeur définie, la protection contre le courant continu configurée au niveau de la partie segmentée transmet le courant de défaut et la direction de courant de défaut à une protection de courant continu adjacente, et détermine un point de défaut en fonction des courants de défaut et des directions de courant de défaut de la protection contre le courant continu elle-même et de la protection contre le courant continu adjacente ; puis la protection contre le courant continu qui est la plus proche autour du point de défaut fonctionne et le commutateur de charge est éteint pour localiser le défaut. Une fois que la défaut est localisé, la protection contre le courant continu exécutant la localisation de défaut envoie une instruction au convertisseur pour rétablir l'alimentation électrique, et envoie en même temps une instruction à la protection contre le courant continu configurée sur un commutateur d'interconnexion de commuter vers le commutateur, ce qui permet de récupérer l'alimentation électrique sur une région sans défaut.
