It can convert physical pressure parameters such as gas and liquid sensed by the pressure measuring element sensor into standard electrical signals to supply secondary instruments such as indicator alarms, recorders, regulators, etc. for measurement, indication and process regulation.

[0003] During the production process of pressure transmitters, the production line needs to be supervised. At present, it is difficult to accurately judge the production quality of the production line when supervising the production line of pressure transmitters. When the production quality of the production line is judged to be good, it is impossible to comprehensively evaluate the control performance of the production line, which is not conducive to the management personnel to make reasonable improvement measures for the production line, and increases the difficulty of production line supervision;

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0008] At the end of the production of pressure transmitters, quality inspection is carried out on the produced pressure transmitters. The pressure transmitter quality inspection collection module collects various performance data of the corresponding pressure transformer and sends the various performance data of the corresponding pressure transmitter to the performance abnormality decision module and the production line supervision end;

[0009] The performance abnormality decision module analyzes the quality status of all pressure transmitters produced by the pressure transmitter production line during the detection period, generates a production line optimization signal or a quality inspection qualified signal through analysis, and sends the production line optimization signal to the production line supervision end, and sends the quality inspection qualified signal to the pressure transmitter production line analysis module;

[0010] When the pressure transmitter production line analysis module receives a quality inspection qualified signal, it will conduct a comprehensive evaluation of the management performance of the pressure transmitter production line during the inspection period, generate a production line monitoring optimization signal or a production line monitoring abnormality signal through analysis, and send the production line monitoring optimization signal or the production line monitoring abnormality signal to the production line supervision end; when the production line supervision end receives the production line optimization signal or the production line monitoring abnormality signal, it will issue a corresponding warning.

[0024] Compare the raw material area environmental monitoring value with the preset raw material area environmental monitoring threshold. If the raw material area environmental monitoring value exceeds the preset raw material area environmental monitoring threshold, it is determined that the raw material preparation area is in an environmental management abnormality state. The total time duration of the raw material preparation area in the environmental management abnormality state during the detection period is obtained and marked as the raw material area environmental management abnormality time value.

[0025] and collecting the real-time storage quantity of each raw material accessory in the raw material preparation area, comparing the real-time storage quantity with the corresponding preset real-time storage quantity threshold, and if the real-time storage quantity does not exceed the preset real-time storage quantity threshold, judging that the corresponding raw material accessory is in a replenishment delay state; obtaining the total duration of the corresponding raw material accessory in the replenishment delay state during the detection period and marking it as the replenishment delay duration, calculating the average of the replenishment delay durations of all raw material accessories during the detection period to obtain a replenishment delay detection value, and marking the replenishment delay duration with the largest value during the detection period as the replenishment delay detection amplitude value;

[0038] Figure 2 This is a system block diagram of Embodiment 2 and Embodiment 3 of the present invention. DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Embodiment 1: Figure 1 As shown, the operation supervision system for the pressure transmitter production line proposed by the present invention includes a pressure transmitter quality inspection and collection module, a performance abnormality decision module, a pressure transmitter production line analysis module and a production line supervision terminal;

[0041] At the end of the production of pressure transmitters, quality inspection is carried out on the produced pressure transmitters. The pressure transmitter quality inspection and collection module collects various performance data of the corresponding pressure transformer, and sends the various performance data of the corresponding pressure transmitter to the performance abnormality decision module and the production line supervision end, so that the management personnel can have a detailed understanding of the quality status of each pressure transmitter produced, so as to make corresponding treatment measures for each pressure transmitter and provide data support for the analysis process of the performance abnormality decision module.

[0042] A detection period is set, preferably, the detection period is fifteen days; the performance abnormality decision module analyzes the quality status of all pressure transmitters produced by the pressure transmitter production line during the detection period, generates a production line optimization signal or a quality inspection qualified signal through analysis, and sends the production line optimization signal to the production line supervision end;

[0043] When the production line monitoring end receives the production line optimization signal, it issues a corresponding warning to remind the management personnel to take corresponding improvement measures for the corresponding pressure transmitter production line, and strengthen the subsequent operation supervision of the corresponding pressure transmitter production line to ensure the quality of the pressure transmitters produced subsequently and reduce the supervision difficulty of the management personnel; the specific analysis process of the performance abnormality decision module is as follows:

[0044] Obtain various performance data of the corresponding pressure transmitter (including measurement accuracy, zero point output and other performance data), mark the corresponding performance data as analysis object i, where i is a natural number greater than 1; compare various performance data with corresponding preset data requirements, if the analysis object i does not meet the corresponding preset data requirements, indicating that the corresponding performance of the pressure transmitter is abnormal, then the corresponding analysis object i is marked as the warning object of the corresponding pressure transmitter;

[0045] If there is a warning object in the corresponding pressure transmitter, indicating that the quality condition of the corresponding pressure transmitter is not good, the corresponding pressure transmitter is marked as a non-optimal target; the number of non-optimal targets produced by the pressure transmitter production line during the detection period is obtained and the ratio is calculated with the total number of pressure transmitters produced by the pressure transmitter production line during the detection period to obtain the pressure transmitter abnormal condition value; wherein, the larger the value of the pressure transmitter abnormal condition value, the worse the production performance of the corresponding pressure transmitter production line during the detection period;

[0046] Compare the abnormal value of the pressure transmitter with the preset abnormal threshold of the pressure transmitter. If the abnormal value of the pressure transmitter exceeds the preset abnormal threshold of the pressure transmitter, it indicates that the production performance of the corresponding pressure transmitter production line is poor during the detection period, and the corresponding pressure transmitter production line needs to be optimized and improved, and then generate a production line optimization signal;

[0047] If the abnormal condition value of the pressure transmitter does not exceed the preset abnormal condition threshold of the pressure transmitter, the number of pressure transmitters involved in the analysis object i marked as the warning object during the detection period is defined as the warning condition value, and the warning condition value is calculated by ratioing the total number of pressure transmitters produced by the pressure transmitter production line during the detection period to obtain the warning analysis value; wherein, the larger the value of the warning analysis value, the greater the probability that the pressure transmitters produced by the pressure transmitter production line during the detection period have corresponding performance abnormalities;

[0048] The early warning analysis value is numerically compared with the corresponding preset early warning analysis threshold. If the early warning analysis value exceeds the corresponding preset early warning analysis threshold, it indicates that the pressure transmitters produced by the pressure transmitter production line during the detection period are more likely to have corresponding performance abnormalities, and the performance corresponding to the analysis object i is marked as error-prone performance; if there is error-prone performance, it indicates that targeted improvement measures need to be taken in time for the corresponding performance abnormalities, and a production line optimization signal is generated.

[0049] Furthermore, if there is no error-prone performance, the ratio of the warning detection value to the corresponding preset warning detection threshold is calculated to obtain the warning measurement value, the average of all warning measurement values ​​is calculated to obtain the warning measurement value, and the warning measurement value with the largest value is marked as the warning amplitude value;

[0050] The performance quality inspection decision value Zaw is obtained by numerically calculating the abnormal value Qfg, the warning analysis value Qwe and the warning amplitude value Qwg of the pressure transmitter through the formula Zaw=uy1*Qfg+(uy2*Qwe+uy3*Qwg) / 2; wherein uy1, uy2 and uy3 are preset proportional coefficients, uy1>uy2>uy3>0; and the larger the value of the performance quality inspection decision value Zaw is, the better the overall quality of the products produced by the corresponding pressure transmitter production line during the inspection period is;

[0051] The performance quality inspection decision value Zaw is numerically compared with the preset performance quality inspection decision threshold. If the performance quality inspection decision value Zaw exceeds the preset performance quality inspection decision threshold, it indicates that the product quality produced by the corresponding pressure transmitter production line during the inspection period is generally poor, and a production line optimization signal is generated; if the performance quality inspection decision value Zaw does not exceed the preset performance quality inspection decision threshold, it indicates that the product quality produced by the corresponding pressure transmitter production line during the inspection period is generally good, and a quality inspection qualified signal is generated.

[0052] The performance abnormality decision module sends the quality inspection qualified signal to the pressure transmitter production line analysis module. When the pressure transmitter production line analysis module receives the quality inspection qualified signal, it will conduct a comprehensive evaluation on the management performance of the pressure transmitter production line during the inspection period, generate a production line monitoring excellent signal or a production line monitoring abnormal signal through analysis, and send the production line monitoring excellent signal or the production line monitoring abnormal signal to the production line supervision end;

[0053] When the production line monitoring end receives the production line monitoring abnormality signal, it issues a corresponding warning to remind the management personnel to adjust the subsequent management plan for the pressure transmitter production line in time, strengthen the subsequent operation management of the corresponding pressure transmitter production line, ensure the subsequent production efficiency and production stability, and further reduce the supervision difficulty of the management personnel; the specific analysis process of the pressure transmitter production line analysis module is as follows:

[0054] The material management symbol HY-1 or HY-2 and the operation management symbol HP-1 or HP-2 corresponding to the pressure transmitter production line during the detection period are obtained, and the material management symbol and the operation management symbol are intersection analyzed. If HY-2∩HP-2 is obtained, it indicates that the management performance of the corresponding pressure transmitter production line during the detection period is generally good, and a production line monitoring signal is generated; the other cases (HY-1∩HP-1, HY-1∩HP-2 or HY-2∩HP-1) indicate that the management performance of the corresponding pressure transmitter production line during the detection period is generally poor, and a production line monitoring signal is generated.

[0055] Embodiment 2: Figure 2 As shown, the difference between this embodiment and the first embodiment is that the pressure transmitter production line analysis module is communicatively connected to the raw material area management and monitoring module, and the raw material area management and monitoring module monitors the raw material preparation area corresponding to the pressure transmitter production line, and analyzes the management performance of the raw material preparation area during the detection period, and assigns the material management symbol HY-1 or HY-2 through the analysis;

[0059] Compare the raw material area environmental monitoring value Ysg with the preset raw material area environmental monitoring threshold. If the raw material area environmental monitoring value Ysg exceeds the preset raw material area environmental monitoring threshold, indicating that the environmental condition of the raw material preparation area is poor, the raw material preparation area is judged to be in an environmental management abnormality state, and the total time length of the raw material preparation area in the environmental management abnormality state during the detection period is obtained and marked as the raw material area environmental management abnormality time value;

[0060] and collecting the real-time storage quantity of each raw material accessory in the raw material preparation area, comparing the real-time storage quantity with the corresponding preset real-time storage quantity threshold, and if the real-time storage quantity does not exceed the preset real-time storage quantity threshold, determining that the corresponding raw material accessory is in a replenishment lag state;

[0061] The total time duration of the corresponding raw material accessories in the replenishment delay state during the detection period is obtained and marked as the replenishment delay time duration, the replenishment delay time durations of all raw material accessories during the detection period are averaged to obtain the replenishment delay detection value, and the replenishment delay time duration with the largest value during the detection period is marked as the replenishment delay detection amplitude value;

[0063] The raw material area pipe table value LP is numerically compared with the preset raw material area pipe table threshold. If the raw material area pipe table value LP exceeds the preset raw material area pipe table threshold, it indicates that the management performance of the raw material preparation area for the corresponding pressure transmitter production line during the detection period is generally poor, and the material management symbol HY-1 is assigned; if the raw material area pipe table value LP does not exceed the preset raw material area pipe table threshold, it indicates that the management performance of the raw material preparation area for the corresponding pressure transmitter production line during the detection period is generally good, and the material management symbol HY-2 is assigned.
