The utility model discloses a kind of passenger car pneumatic motor systems, including air compressor, air tank and gas module, air compressor is connected with air tank and gas module respectively by distribution valve group and supplies gas for it, distribution valve is connected with several pneumatic motor, and pneumatic motor is used to drive the execution module of vehicle work, the utility model replaces the power source for driving execution mechanism operation by common electric motor into pneumatic motor, and using the air supply unit of vehicle carries out air supply to pneumatic motor, on one hand, compared with electric motor, pneumatic motor can use simple flow control valve to realize system control, without equipping complex electronic control system, simple structure, subsequent maintenance cost is less, purchase cost also compared with electric motor has reduced, can effectively reduce the cost of operation execution unit, and more conducive to the demand of vehicle light weight;On the other hand, multiple execution mechanism can share a set of air supply unit, improve the utilization of air supply unit, strong applicability.

This utility model belongs to the field of air filtration technology and relates to a static axial outlet plate and frame air filter. The plate and frame air filter has an air inlet, an air outlet, and a filter element frame for mounting filter elements. Two filter element frames I are sealed at one end to a side plate I of the plate and frame air filter, and the side plate I is connected to the air outlet or the air inlet of the plate and frame air filter. Multiple filter element frames II are arranged between the two filter element frames I. The filter element frames II are parallel to the filter element frames I. Both ends of each filter element frame II are connected to adjacent filter element frames I or adjacent filter element frames II through connecting elements to form multiple interconnected U-shaped air ducts. The connecting elements are connecting plates or connecting frames for mounting filter elements. This utility model can meet the needs of larger air intake volume, so that the internal space of the filter is maximized. Under the same air intake volume, the volume of the plate and frame air filter is reduced by 60%-70%.

The present application belongs to the technical field of computer-aided disease diagnosis and treatment, and discloses a medical diagnosis method and device based on cross-modal semantic hash retrieval, comprising: using an artificial neural network to hash encode category annotation information to form a semantic similarity preserving classifier; using the semantic similarity preserving classifier to guide the training process of multiple modal artificial neural network encoders; using the trained encoder to hash encode different modal medical data; and completing medical diagnosis through cross-modal semantic hash retrieval. The present application has the following advantages in medical diagnosis: low storage and computing resource consumption; good semantic representation ability, i.e. the hash encoding of samples can simultaneously represent the inter-class semantic relationship of samples and maintain intra-class mutual aggregation; and the ability to simultaneously process single-modal medical data-based and multi-modal medical data-based medical diagnosis tasks.
