PROCEDURE FOR CONTROL OF TECHNICAL STATE OF CROSSES IN MAINS AND SYSTEM FOR ITS IMPLEMENTATION |
| 摘要 |
FIELD: machine building. ^ SUBSTANCE: procedure consists in measurement of electric resistance R between pair of crossing mains and in continuous comparison of measured values with corresponding reference value R0. At R<R0 there is diagnosed a threat of hazardous condition of crossing. The system of control over technical state of crosses in mains consists of a current source and of an amplifier connected in parallel to the controlled pair of crossing mains in the point of their crossing. Further, the system consists of serially connected analogue-digital converter and micro-processor, of a unit for transmitting digital information and of a recorder. Also, the output of the amplifier is connected to the input of the analogue-digital converter, while outputs of the micro-processor are connected to the recorder and to controlled inputs of the current source and unit for transmitting digital information. ^ EFFECT: avoiding threat of hazardous state of main crossing. ^ 14 cl, 1 dwg |
