Intelligent terminal for timely and automatically collecting LED digital display data

Abstract

The invention discloses an intelligent terminal for timely and automatically collecting LED digital display data. The intelligent terminal comprises a bottom layer, a middle layer and a top layer. The bottom layer adopts an LED nixie tube light emitting state detection device arranged on a PCB, small holes, corresponding to centers of LED nixie tubes, are formed in the PCB, and photodiodes are welded on the small holes. The middle layer adopts a MCU as a controller, and the MCU is connected with an LED state identification module, an LED decoding module, a secondary display module and a serial communication bus transmission module. The top layer adopts the form of LED nixie tubes for secondary display of readings on the LED nixie tubes. The intelligent terminal automatically achieves data collection in the operation process of equipment and omits links such as manual data recording and data logging, thereby reducing workload of operators. The accuracy and reliability of data is greatly improved, the timeliness of data collection is greatly improved, and automatic collection is achieved.

Description

Technical field [0001] The invention relates to the field of automatic control and monitoring, in particular to an intelligent terminal for real-time and automatic collection of LED digital display data. Background technique [0002] In the manufacturing, reliability testing, process quality monitoring and other processes of aviation, aerospace, weapons, ships and other defense manufacturing industries, as well as automobiles, electricity, energy and other fields, various important processes are required in accordance with quality system regulations such as ISO90001 or GJB Activities must be defined in advance, recorded during the event, and traceable afterwards. The key process equipment that needs to be included in the monitoring system, many parts of which use LED digital tube headers for data measurement and display, and these process equipment themselves cannot be related to the data. The processing system performs direct communication to realize data transmission, and these...

Problems solved by technology

However, there are several problems in this data collection method: (1) The accuracy of the data cannot be guaranteed, and errors caused by workers' emotions and mistakes are inevitable from the two links of manual recording and input; (2) Increases the workload of workers, especially requiring workers to input manually recorded data into the information management platform, which will increase the workload of workers, generate resistance, and affect the promotion and application of the production management process manage
