Forced switching module of working mode of nuclear industrial robot in nuclear environment

Abstract

The invention provides a forced switching module of working modes of a nuclear industrial robot in a nuclear environment, and the forced switching module belongs to the field of robot control. The forced switching module aims to solve the problem that a robot is trapped in an accident region and is difficult to retrieve when the robot is out of control due to communication outage. According to the forced switching module, a signal intensity detector is arranged outside a radiation protection outer shell which is internally provided with a control circuit, the control circuit comprises a storage battery GB, an intermediate relay K1, a comparator A1, a slide rheostat RP, and NPN transistors VT1 and VT2. An inverting input end of the comparator A1 is connected to a wireless intensity signal output end of the signal intensity detector, a same-phase input end of the comparator A1 is connected to the slide rheostat RP, an output end of the comparator A1 is subjected to two-stage amplification through the VT1 and VT2 to drive a K1 coil to obtain electricity, and an independent control mode is started forcedly.

Description

technical field [0001] The invention relates to a circuit switching module, which belongs to the field of robot control. Background technique [0002] Nuclear energy and nuclear technology are hailed as one of the most important creations of the 20th century. While benefiting mankind, they have brought nuclear safety issues and serious threats to public safety. The continuous nuclear accidents have sounded the alarm for people time and time again. [0003] Nuclear accidents are different from ordinary safety accidents. People cannot directly enter the site of a nuclear accident and its surroundings due to the presence of high doses of radioactive substances. In order to obtain the radiation field distribution data in the nuclear emergency state, it is necessary to conduct on-the-spot, fast and accurate measurement at the accident site, and at the same time make a comprehensive judgment based on the source item information provided by the accident unit to obtain the radiatio...
