Abstract: A power supply device including a register circuit, an internal control circuit, and a storage circuit is disclosed. The register circuit includes a first sub-register circuit and a second sub-register circuit. The first sub-register circuit and the second sub-register circuit are configured to take turns to temporarily store a data transmitted form an external control circuit. The internal control circuit is coupled to the register circuit, and the internal control circuit is configured to obtain the data temporarily stored in the first sub-register circuit and the second sub-register circuit. The storage circuit is coupled to the internal control circuit, and the storage circuit is configured to obtain the data from the internal control circuit and to store the data.

Abstract: A high temperature-resistant fire extinguishing robot, comprising: a high temperature-resistant robot chassis system and a high temperature-resistant turret system. The high temperature-resistant robot chassis system carries the high temperature-resistant turret system to perform movements and obstacle avoidance, provides the high temperature-resistant turret system with energy, and further comprises: a high temperature-resistant tract drive system, a thermal protection system, and a control and sensor system, the high temperature-resistant track drive system being arranged outside of the thermal protection system, and the control and sensor system being arranged within the thermal protection system.

Abstract: A high temperature-resistant wheel, comprising: an elastic hub assembly (1), which has a thermal insulation layer integrated therewith so as to insulate the elastic hub assembly (1) from exterior high temperatures; and a rigid wheel barbed ring (2), which has the elastic hub assembly (1) fastened inside and rotates together with the elastic hub assembly (1). A robot, which comprises the high temperature-resistant wheel.

Abstract: Provided is an anti-islanding protection system. The system is applied to a low-voltage distributed generation resource (DGR) and includes a box, a reverse power protector, a protection module and an output controller. The reverse power protector has an end connected to a first current transformer and has another end connected to the output controller. The reverse power protector is configured to provide reverse power protection for the low-voltage DGR. The output controller has an end connected to the protection module and the reverse power protector and has another end connected to a grid-connection switch of the low-voltage DGR. The output controller is configured to control the grid-connection switch to turn off when reserve power is detected. The protection module has an end connected to a second current transformer and has another end connected to the output controller.
