Abstract: A dirt treatment apparatus, a cleaning device and a control method for the cleaning device are provided. The dirt treatment apparatus includes: a box body and a separation apparatus, in which the separation apparatus is assembled in the box body, the box body is provided with a suction channel allowing for communication between an interior and an exterior of the box body, and an air outlet; the separation apparatus includes a main body member and a blocking member; the main body member is provided in the box body, and the main body member and an inner wall of the box body define a separation channel in communication between the suction channel) and the air outlet; and the blocking member is fitted on the main body member and blocks a flow path of all airflows flowing from the suction channel to the air outlet.

Abstract: A distributed test method applicable to a system-level test of intelligent high voltage equipment. The method includes: firstly, carrying out unified modeling on test equipment behaviors according to test requirements, and generating a general test case for ensuring accuracy and coordination of test behaviors and test time sequences under various work conditions; then, extracting, according to a feature element of role defining, sequence states of same roles from the general test case, and recombining the sequence states according to an execution sequence so as to form test sub-cases of the roles; finally, executing, by each piece of test equipment, corresponding test sub-cases to achieve cooperative linkage by means of information interaction, so as to accomplish entire process simulation of the test conditions.

Abstract: An electric clamping bracket includes: a housing and a clamp assembly. The electric clamping bracket further includes a drive motor; the clamp assembly includes a left clamping frame and a right clamping frame; the left clamping frame and the right clamping frame extend forward and are respectively disposed on two opposite sides of the housing; the left clamping frame or/and the right clamping frame are slidably connected to the housing; and the drive motor drives the left clamping frame and/or right clamping frame so that the left clamping frame and the right clamping frame are close to each other or far apart opposite to each other. A control system of the electric clamping bracket is also disclosed. The electric clamping bracket uses the motor to drive the clamp assembly to clamp or release a mobile device, thus achieving automatic clamping or releasing of the clamping bracket.
