Abstract: A detection method for an air-conditioning system includes detecting whether the input power of the compressor of the air-conditioning system is lower than the power threshold. The method includes obtaining the evaporation saturation temperature of the evaporator of the air-conditioning system and obtaining the condensation saturation temperature of the condenser of the air-conditioning system when the input power is lower than the power threshold. When detecting that the evaporation saturation temperature is greater than the condensation saturation temperature, the method includes determining that an abnormal phase change is occurring and operating the compressor in the full-speed mode.

Abstract: An outdoor cabinet is disclosed and includes a cabinet, an active damper and a passive damper. The cabinet includes an air inlet, an air outlet and an accommodation space. The accommodation space is in communication with an outdoor environment through the air inlet and the air outlet, respectively. The active damper is arranged adjacent to the air inlet. The passive damper includes an exhaust fan and a damper blade. The exhaust fan is arranged adjacent to the air outlet. The damper blade is arranged between the air outlet and the outdoor environment. When the exhaust fan is in operation, the damper blade allows a heat-dissipation airflow to be discharged from the air outlet to the outdoor environment. When a wind pressure of the outdoor environment is greater than a wind pressure of the accommodation space, the damper blade closes the air outlet to protect electronic devices installed in the cabinet.

Abstract: The present disclosure provides a cooling system, including an air-cooling device and a water-cooling device. The air-cooling device includes a first fan, an evaporator, a first condenser, and a second fan. The first fan is arranged in a first cooling room and configured to blow a hot air inside a rack into a first cooling room. The evaporator is arranged in the first cooling room. The first condenser is arranged in a second cooling room. The second fan is arranged in the second cooling room and configured to blow an outside air into the second cooling room. The water-cooling device includes a radiator. The radiator is arranged in the second cooling room and configured to receive a hot liquid from an electronic device in the rack through a third pipeline and transmit a cold liquid to the electronic device through a fourth pipeline.

Abstract: A three-finger mechanical gripper system is provided, which includes a torque sensor, a three-finger mechanical gripper, an image capturing module and a controller. The three-finger mechanical gripper is connected to the torque sensor. The controller is connected to the torque sensor, the three-finger mechanical gripper and the image capturing module. The image capturing module captures the image of a training object. The controller controls the three-finger mechanical gripper to grip the training object by a plurality of gripper postures respectively and calculates the torque information of each gripper posture according to the measured values of the torque sensor. Then, the controller performs a training process according to the image of the training object and the torque information of the gripper postures in order to obtain a training result of the training object.
