Multi-dimensional nuclear safety door detection and verification device

Abstract

The invention discloses a multi-dimensional nuclear safety door detection and verification device. The device adopts a single-chip microcomputer as a detection and control core for completing movement control, position detection, coordinate calculation and data result display of the whole device; a stepping motor is adopted as driving power, a ball screw nut machine is used as an execution mechanism for completing an XYZ three-dimensional coordinate precision movement device, and under the control of the single-chip microcomputer, a ball screw is driven by the stepping motor to rotate, rotation is converted to linear movement by a nut on the screw, and the movement on three-dimensional coordinates can be precisely performed according to the number of steps per rotation of the stepping motor and the pitch of the screw; a circular arc surface rotation mechanism of a radiation source is arranged on a Z-direction movement device, and the fourth-dimensional movement in the horizontal direction is realized by adopting rotational angle control of the stepping motor. The multi-dimensional nuclear safety door detection and verification device disclosed by the invention has the benefits that the multi-dimensional nuclear safety door detection and verification device replaces manpower to perform radioactive safety detection, and high efficiency and safety are realized.

Description

technical field [0001] The invention belongs to the technical field of single-chip microcomputers, and relates to a multi-dimensional nuclear safety door detection and verification device. Background technique [0002] With the construction of nuclear power plants, there are more and more people working in nuclear power plants. The staff in the radiation control area will be exposed to ray radiation and contaminated with radioactive substances. Nuclear safety gates are established in nuclear power plants to detect the radiation and contamination of radioactive substances by personnel entering the radiation control area. The radiation and contamination can be detected in time through the detectors or instruments installed on the safety door, and corresponding measures can be taken to eliminate the danger. To ensure the safety of personnel working in nuclear power plants, the nuclear safety door is a very important device. The normal operation of the equipment is to ensure the...
