The invention discloses an intelligent attendance system based on machine vision, comprising an information collection and processing terminal, an access control system, a remote monitoring terminal and a communication module. The information collection and processing terminal includes a controller, an information storage module, a personnel information collection module, a measurement Point information acquisition module, human-computer interaction module and power supply module, the controller matches the collected personnel information or environmental parameter information with the corresponding information pre-stored in the information storage module, and transmits the matching result to the access control system through the communication module and remote monitoring terminal. The present invention adopts the combination of machine vision module and other modules, improves the accuracy of attendance results and improves the efficiency of attendance, and adopts the wireless communication data transmission method with ZigBee networking, so that its application scene can be extended from a fixed position To multiple locations, it avoids cumbersome wiring and significantly improves the flexibility of fingerprint attendance equipment deployment.

The invention discloses small-sized portable electric heat storage equipment. The equipment comprises a heat storage part, an air conveying part and a heat acquisition part. The heat storage part comprises a heat storage body, and a heat storage oven is embedded in the central axis of the heat storage body; the air conveying part comprises a fan arranged below the heat storage body; the heat acquisition part covers the heat storage part and comprises a cover body, a cover plate, an air exhaust plug and multiple ventilation pipes; an air exhaust cavity which runs through the cover body is formed in the center of the cover body, and the inner wall of the air exhaust cavity inclines; the cover plate covers the air exhaust cavity and is provided with an adjustment component; the air exhaust plug is arranged in the air exhaust cavity and blocks the bottom of the air exhaust cavity, and the height of the air exhaust plug is smaller than that of the air exhaust cavity; the bottom of the adjustment component is fixedly connected with the upper surface of the air exhaust plug, the air exhaust plug moves up and down in the air exhaust cavity through the adjustment component, after the air exhaust plug moves upwards, the ventilation pipes on the heat storage body can be communicated with the air exhaust cavity, and heat dissipation holes are formed in the cover plate. According to the electric heat storage equipment, energy can be provided for power utilization and heat utilization areas temporarily.

The invention discloses a detecting rod for multi-point layered grain conditions. The detecting rod for the multi-point layered grain conditions includes a hollow insert attracting pipe and an insertdrawing pipe, wherein insert attracting holes are formed in the pipe wall of the insert attracting pipe. The detecting rod for the multi-point layered grain conditions further includes an upper folding pipe, a traction block, an insert collecting machine and a lower folding pipe, wherein the upper folding pipe, the traction block, the insert collecting machine and the lower folding pipe are located in the insert attracting pipe and arranged from top to bottom in sequence. The outer walls of the upper folding pipe and the lower folding pipe are attached to the inner wall of the insert attracting pipe. Gaps are reserved between the lower end surface of the traction block and the upper end surface of the insert collecting machine. The traction block and the insert collecting machine are correspondingly connected with the upper folding pipe and the lower folding pipe. A drive device is further arranged on the insert attracting pipe, and the drive device is used for driving the traction block and the insert collecting machine and slides in the axial direction of the insert attracting pipe in a single degree of freedom mode. The detecting rod for the multi-point layered grain conditionscan not only detect a fixed point of a space region in a granary, but also can detect the grain conditions at different depths of a grain bulk at the fixed point.
