Fault locating device for testing industrial measurement and control instrument

Abstract

The invention discloses a fault locating device for testing an industrial measurement and control instrument. The fault locating device comprises a wireless acquisition terminal and a locating controlserver, wherein the wireless acquisition terminal comprises a small current fault locating mechanism for electrical property detection in an instrument line and a compound eye imaging and locating mechanism for visual location monitoring; communication ports of the fault locating mechanism and the compound eye imaging and locating mechanism are connected with a wireless communication ranging module for transmitting and receiving a wireless signal; the wireless communication ranging module comprises a ranging register; an SPI (Serial Peripheral Interface) interface of the ranging register is connected with a port of an embedded controller; the output end of the ranging register is connected with a radio frequency conversion module for converting a digital electric signal into a radio frequency signal; and a transmitting and receiving antenna is mounted at the transmitting and receiving end of the radio frequency conversion module. The fault locating device disclosed by the invention realizes real-time detection, precise locating and image monitoring of an instrument fault and can effectively save labor cost and resources; and a fault is maintained in time to guarantee the working stability of the whole device.

Description

technical field [0001] The invention relates to the field of measurement and control instrument devices, in particular to a fault location device for testing industrial measurement and control instruments. Background technique [0002] Industrial automation instruments are instruments that detect, display, record or control process parameters in the process of industrial production, also known as industrial instruments that detect, display, record or control process parameters, or (industrial) process detection and control instruments .
