Detailed Description
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings and embodiments, and it is to be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The automatic collection system for the temperature after aluminum liquid degassing according to the embodiment of the invention is described below with reference to fig. 1 to 5.
An automatic temperature acquisition system after molten aluminum degassing comprises a data acquisition device, wherein the data acquisition system can detect the peak temperature (namely the highest temperature value) of molten aluminum after degassing; the data transmission device can transmit the data acquired by the data acquisition device; and the data analysis device is connected with the data acquisition device through the data transmission device and analyzes the received data to form a data report. The data acquisition device comprises a temperature detector. The temperature detector comprises a plurality of temperature detectors arranged at different positions. The data transmission device comprises a high-temperature-resistant cable, and the data acquisition device is connected with the high-temperature cable through a data interface. The galvanized pipe is arranged on the outer side of the high-temperature cable, so that the stability and the noninterference of the data transmission process are ensured. The data analysis device comprises a computer, and the computer can record and store the peak temperature and form a data report.
In some embodiments, the data acquisition device: most temperature measurement all uses ordinary temperature measuring instrument at present, shows the temperature during the measurement and is recorded by the operative employee, and this scheme uses this island electricity temperature detector of this day, and this instrument has data interface can realize data transmission.
The data transmission device: and the temperature measuring instrument is connected with the computer by using a network cable. The communication between the instrument and the computer uses a high temperature resistant cable to ensure the stability of data transmission and reduce the interference to pass through the galvanized pipe.
A data analysis device: the data transmission device collects and updates the temperature measuring instrument in real time (the read numerical value is taken to an internal chip of the instrument and has no difference with instrument display), and performs data analysis and storage according to given conditions. The working state of the field instrument is the process of room temperature → temperature rise → temperature measurement → temperature reduction → room temperature, the general data recording analysis only records the working process of the whole instrument, the recording curve needs to be inquired one by one to check the measured temperature, and the inaccurate inquiry condition can occur, the temperature measurement system polls the temperature measurement instrument once per second in a polling mode after degassing, simultaneously records the temperature value detected by each sensor in real time and displays the polling result in a window. When a field worker inserts the thermocouple into the aluminum liquid bag, the temperature measuring software detects the temperature rise and compares the temperature rise with the temperature value of the last second in real time. When the temperature of the road is detected to stop rising stably for 3 seconds, the temperature value (namely the highest temperature value) of the road is separately displayed and stored after the temperature drops and is added into the historical record.
The record content includes information such as date, time, shift, and corresponding machine, etc., and the history record may be queried in units of days (months) to generate reports as shown in fig. 4 and 5 for each shift, or may be exported as an EXCEL file for analysis by technicians.
In some embodiments, as shown in fig. 1, the temperature after degassing is detected at 5 temperature measuring points on site, the temperature is transmitted to a computer through a data line, collected data is analyzed and summarized through software, and a report is generated through data analysis.
The most important problem in the scheme is that the software value taking is carried out, the detection process is that an operator puts a thermocouple into a pouring ladle, the temperature of an instrument rises, the temperature can be collected when the temperature rises to the maximum and is stable for three seconds, the initial value taking mode of the scheme is that the temperature rises stably for three seconds, but a stable 3-second process is still carried out when the temperature drops to a certain temperature after the value taking, so that the temperature measuring system collects 2 times of data each time to cause inaccurate data, in order to avoid the problem, the temperature value before the temperature drop (namely the maximum value of the temperature) is taken when the temperature drops after the temperature rise stops is finally confirmed through the analysis of the data, the temperature value is unique and is also required by the process, and the problem of inaccurate value taking is perfectly solved.
And after degassing, the temperature measurement system software polls the temperature measurement instrument once per second in a polling mode, simultaneously records the temperature value detected by each sensor in real time and displays the polling result in a window. The left graph is the software data record real-time trend curve. And the manipulator detects the temperature of the casting ladle aluminum liquid after degassing, and temperature data are displayed on the instrument and transmitted to the computer through a data line. And the temperature data is transmitted to computer software in real time to analyze the data, and the temperature value is read and stored in the computer after the temperature curve is stopped rising and falls. The system records the temperature value after degassing according to the set value-taking rule and displays the temperature value on a computer screen, data can be inquired in a historical report, a daily report can also be generated, and EXCEL can also be exported to facilitate data analysis of technical personnel.
Compared with the prior art, the automatic temperature acquisition system after molten aluminum degassing has the following advantages:
after the system is adopted, all data are directly accessed into a computer, so that the condition that the records of field operators are inaccurate is avoided; on the other hand, all data can be inquired, analyzed and exported to provide data support for quality analysis, tracing and the like in the future.
