A function unit having easy exchangeability in a dual wiring system is provided. The function unit is detachably connected to a gate device mounted in a wall surface of a structure, and connected to both of an electric power line and an information line previously installed in the structure. The function unit has at least one of functions for supplying electric power from the electric power line, outputting information from the information line and inputting information into the information line when connected with the gate device. The function unit has a module connector, which is configured to simultaneously establish both of supplying the electric power from the gate device to the function unit, and making a signal transmission between the gate device unit and the function unit when connected to a module port formed at the gate device. To improve function expandability, an additional function unit may be detachably connected to the function unit.

The electrical system comprises a high-voltage battery, a battery management system (1), a key switch (16), an electricity supply unit, an intelligent decision-making and control unit, a sensor unit and an actuator unit, wherein the high-voltage battery is connected with the battery management system (1) through an electrical circuit; the key switch (16) is provided with an OFF gear, an ACC gear, an ON gear and a START gear; the electricity supply unit comprises a main accumulator (12) and an auxiliary accumulator (11); the electrical circuit comprises a main ACC circuit, an auxiliary ACC circuit, an ON circuit, a START circuit and a constant electric circuit which is connected with a positive pole output terminal of the main accumulator (12). Compared with the prior art, the electrical system disclosed by the invention has the advantages that requirements of a control unit and a wire-controlled system of the electric intelligent vehicle for redundancy are met, hardware redundancy and electricity supply redundancy are designed for critical components including a steering unit, a braking unit, a central control unit and the like in the driving of vehicles, and the safety of autonomous vehicles is improved.

The invention relates to a system and method for detecting the quality of a metal cap based on machine vision, used for detecting the quality defect of the metal cap and rejecting the inferior quality product. The detection system comprises an optical imaging device, an image processing device, a rejecting device and a conveying belt, wherein the optical imaging device comprises a planar array industrial camera, a first optical detection sensor and a light source; the image processing device is used for processing the image; and the rejecting device comprises a control circuit board, a second optical detection sensor, a solenoid valve and an injection tube. The method for detecting the quality of the metal cap based on machine vision comprises the following steps of: acquiring an interested maximum outline scale of a template cap image; establishing a rotational invariance characteristic template matrix for the template cap image; acquiring a round outline of the cap to be detected according to the interested maximum outline scale; calculating the rotational invariance characteristic matrix in the coverage of the round outline of the cap to be detected; and matching the rotational invariance characteristic matrix with the rotational invariance characteristic template matrix, so as to judge whether the cap to be detected is a qualified product or an inferior product.
