Abstract
The utility model discloses a liquid nitrogen container temperature monitoring system, comprising an one -chip microcomputer, the singlechip is connected with platinum resistance, power adapter, storage module, constant -current module, display module, button module, alarm module respectively, arranges the platinum resistance in the liquid nitrogen container inside temperature measurement that carries on, the singlechip passes through radio communication and is connected with the surveillance center. The utility model discloses the precision is high, stability is good, can real time monitoring, centralized management, work efficiency be high.
Description
Technical field
This utility model belongs to liquid nitrogen container field, particularly relates to a kind of liquid nitrogen container temperature monitoring system.
Background technology
Nitrogen is highly stable and molten boiling point is the lowest, the boiling point of nitrogen is-196 DEG C, if temperature will form liquid nitrogen below this at normal atmospheric pressure, if pressurization, liquid nitrogen can be obtained at higher temperatures, liquid nitrogen can be widely used in food refrigerated, metallurgical industry, air separation plant, detergent protection gas etc., liquid nitrogen keeps the temperature in liquid nitrogen container less than-196 DEG C as far as possible when storing, will vaporize higher than this temperature, the most general employing opens liquid nitrogen container acquisition internal temperature, this mode not only certainty of measurement is low, inefficiency, easily discharge nitrogen, and it is dangerous, simultaneously, liquid nitrogen container temperature and high-efficiency management liquid nitrogen container cannot be monitored in real time.
Utility model content
The purpose of this utility model is: for overcoming the deficiencies in the prior art, it is provided that a kind of precision height, good stability, in real time monitoring, the liquid nitrogen container temperature monitoring system of centralized management, greatly improves work efficiency and safety.
For achieving the above object, the technical solution of the utility model is:
A kind of liquid nitrogen container temperature monitoring system, including single-chip microcomputer, described single-chip microcomputer is connected with platinum resistance, power supply adaptor, storage module, constant flow module, display module, key-press module, alarm module respectively, platinum resistance being placed in inside liquid nitrogen container and carry out temperature survey, described single-chip microcomputer is connected with Surveillance center by radio communication.
Further, also including A/D modular converter, output information is carried out analog digital conversion by A/D converter and is delivered to single-chip microcomputer by platinum resistance.
Further, also include that temperature control modules, described temperature control modules are connected with single-chip microcomputer.
Further, described single-chip microcomputer uses Germany RISC.
Owing to have employed such scheme, the beneficial effects of the utility model are: solve the deficiencies in the prior art, this utility model by precision is high, platinum resistance Pt100 of excellent stability is as liquid nitrogen container inside, the temperature within liquid nitrogen container, then measuring accuracy height, good stability is obtained by the resistance gathering platinum resistance；Use constant flow module, it is ensured that the stability of system；The storage module used, has black box memory function, can record the duty of thermometer the machine of all of temperature data and first three winding wire bag that has a power failure；The temperature control modules used, can effectively control the temperature of liquid nitrogen container；And single-chip microcomputer is connected with monitoring by wireless telecommunications, can remotely monitor multiple liquid nitrogen container by Surveillance center, automatically gather, analyze information, centralized management, be greatly saved man power and material.
