Infrared mode intelligent calorimeter calibrating device and method

Abstract

The invention provides a calibration method for an infrared intelligent calorimeter, which is realized through an infrared intelligent calorimeter calibration device and comprises the following steps: 1) installing an intelligent calorimeter to be tested on the installation meter side of a water flow testing bench and manually adjusting a flushing valve on the water flow testing bench at a first flow point to be tested for starting the testing process; 2) manually adjusting the flushing valve on the water flow testing bench at a second flow point to be tested for starting the testing process; 3) and manually adjusting the flushing valve on the water flow testing bench at a third flow point to be tested for starting the testing process. Due to the adoption of the calibration device and the calibration method for an infrared intelligent calorimeter, an intelligent calorimeter to be tested does not need to be taken down from the water flow calibration platform in a testing process. Meanwhile, a hand-held set is used for downloading parameters of the intelligent calorimeter to be tested in an infrared mode. Thus, the device is convenient and flexible in operation, low in testing cost, high in efficiency and less in human error.

Description

technical field [0001] The invention relates to an intelligent heat meter of a heating system, in particular to an infrared smart heat meter calibration device and method. Background technique [0002] At present, for a long time, there have been many problems in my country's heating system, such as unscientific area-based charging and billing methods, serious energy waste, and difficulty in collecting heating fees. Since 2000, the country has been promoting the reform of meter-based charging. [0003] The smart heat meter is an instrument for measuring heat energy. Its working principle is: when water flows through the heat meter installed in the heat exchange system, according to the flow rate given by the flow sensor and the temperature signal of the supply and return water given by the paired temperature sensor, Calculate the thermal energy released or absorbed by the system. For flow measurement, there are currently ultrasonic measurement, non-magnetic measurement, and...

AI Technical Summary

Problems solved by technology

1. Because it is a product that is closely integrated with machinery and electronics, there will be some slight differences in the measurement mechanism of each mechanical watch. The error of the mechanical part is corrected, but the electronic part must be operated and the correction parameters must be downloaded.

2. Since the water flow speed is directly proportional to the movement speed, but it is not a linear relationship, within the flow range, multiple flow points must be calibrated to ensure that the error meets the requirements.

[0006] The disadvantages of the above-mentioned non-magnetic metering technology calibration method are: 1. The link is complicated, requiring meter installation, dismantling, and downloading, especially when a calibration fails, the workload is heavy; 2. The degree of manual intervention is high, such as adjusting flow, recording Data and control valves may introduce some human errors; 3. The download is wired, and the interface needs to be waterproofed on the water flow verification platform; 4. The cost is high, and a computer is needed as an auxiliary tool
