Intelligent data acquisition instrument for measuring temperature of concrete of electric transmission line pole and tower foundation

Abstract

The invention discloses an intelligent data acquisition instrument for measuring temperature of concrete of electric transmission line pole and tower foundation. The intelligent data acquisition instrument mainly comprises temperature sensor interfaces (1), a power supply interface (2), a liquid crystal display screen (3), function buttons (4), a system running data storage unit (5), a central data processing unit (6), a U disk interface (7), a data storage processing unit (8), a communication interface (9), a system clock unit (10), a sleep control circuit (11) and a monitoring system automatic reset circuit (12). The invention has the advantages that: the intelligent data acquisition instrument can be used for measuring the temperature of mass concrete of the electric transmission line pole and tower foundation, the precision and functions of the intelligent data acquisition instrument can meet requirements of mass concrete temperature measurement regulations and specifications, and the intelligent data acquisition instrument has the functions of automatically recording and storing data and giving an alarm when the temperature is too high, is suitable for field environments, and also can be used for measuring the temperature during concrete construction of buildings, bridges, roads and the like, and measuring the temperature of greenhouses, storehouses and liquid.

Description

Technical field: [0001] The invention relates to the field of concrete temperature measurement for transmission line tower foundations, concrete construction of buildings, bridges, roads, greenhouses, warehouses, and liquids, centralized collection and recording of measurement data, and remote transmission. Background technique: [0002] At present, there are various kinds of temperature measuring instruments used in civil and industrial production on the market, with various functions and different uses. Most of these temperature measuring instruments can record data by using mains electricity and using micro-printers to record or communicate with computers. computer records. After the large-volume concrete foundation of transmission line towers is poured, the temperature of the concrete needs to be measured and recorded at multiple locations at regular intervals.

Problems solved by technology

After the large-volume concrete foundation of transmission line towers is poured, the temperature of the concrete needs to be measured and recorded at multiple locations at regular intervals. However, most of the transmission line towers are located in the wild, mountainous and other geographical environments, and none of the above-mentioned temperature measuring instruments can meet the working conditions. For use, in order to overcome the deficiency that the existing temperature monitoring instruments and meters cannot complete the temperature measurement of the large-volume concrete of the transmission line tower foundation, the present invention provides a multifunctional intelligent temperature monitoring data acquisition instrument, which adopts a three-wire system The digital temperature sensor is used as a temperature measurement probe, using a lithium-ion battery as a power supply, with 6 sets of temperature sensor measurement interfaces, and the temperature measurement range is -55°C-+125°C
