Description

Technical Field

[0001] The present invention relates to the technical field of online monitoring, and more specifically, to a pump-suction type phosphine online monitoring system. Background Art

[0002] When disinfecting phosphine in a warehouse environment, due to the complex warehouse environment and the fact that phosphine is a flammable, highly toxic and corrosive gas, the general collection method is to manually use a handheld device to extract gas samples at one location or a fixed device at a fixed location. The collected data is relatively single and cannot reflect the distribution of phosphine gas concentration inside the warehouse as a whole and inside the materials stored in the warehouse. In addition, manual gas extraction sampling is time-consuming and inefficient, and phosphine gas is prone to leakage during operation. With the increasing requirements for warehouse environmental testing, the comprehensiveness of collection and the safety of staff are required to address the above issues. A corrosion-resistant, explosion-proof, high-precision, low-power online phosphine detection system is needed.

[0003] In the existing public documents, the patent with patent announcement number CN210795774U discloses an intelligent phosphine generator system. The online monitoring system includes an alarm device, a text message module, and a digestion liquid spraying device connected to the phosphine gas generating chamber through an emergency treatment system; the intelligent control system is used to intelligently control the start and stop of each system. This technology combines the advantages of various traditional fumigation operations in grain warehouses, and uses dynamic deliquescence to generate phosphine gas outside the warehouse, avoiding personnel entering the warehouse for operation, effectively ensuring the safety of operators, and saving a lot of manpower and material costs; however, the online monitoring system still has the following defects when used.

[0004] When the online monitoring system is performing suction monitoring on phosphine, although it can collect phosphine for alarm, the pump suction part is blocked during the collection and use process, and the sampling data collection is complicated and proofread, and it is difficult to achieve multiple proofreading, which leads to poor collection and monitoring accuracy. Therefore, a pump-suction phosphine online monitoring system is provided. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a pump-suction type phosphine online monitoring system.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a pump-suction type phosphine online monitoring system, comprising a pump-suction module, a collection module and a calibration module, wherein the collection module is connected to the output end of the pump-suction module, the calibration module is connected to the output end of the collection module, the output end of the calibration module is communicatively plugged with a transmission module, a storage module is welded to the output end of the transmission module, and the output end of the storage module is connected to a display and early warning module; a pump-suction anti-blocking switching unit is fixedly installed at the other input end of the pump-suction module, a sampling and impurity removal unit is plugged into the other input end of the collection module, and a multiple proofreading unit is connected to the input end of the calibration module.

[0007] Preferably, the pump suction module is used to periodically sample the gas in the environment or materials, and the pump suction module includes a negative pressure pump, and the number of negative pressure pumps is multiple, the acquisition module is used to collect the phosphine gas data in the sampled gas, and the acquisition end of the acquisition module is made of copper, the calibration module is used to perform data proofreading processing on the data, and the transmission module is used to forward the data and transmit it to the remote server through the MQTT protocol, the storage module is used to receive and store data packets, and the display and warning module is used to centrally display the data and warn of abnormal time, the pump suction anti-blocking switching unit includes a suction sensor, and the output end of the suction sensor is connected to a time alarm, the output end of the time alarm is connected to the dredging electric cylinder, and the output end of the dredging electric cylinder is connected to a negative pressure proofreading sensor.

[0008] In the present technical solution, the suction of the pump is sensed by the suction sensor on the pump suction anti-blocking switching unit through the pump suction anti-blocking switching unit on the input end of the pump suction module. When the suction is low for more than five minutes, the time alarm will sound an alarm, and the unblocking electric cylinder will push and dredge the suction of each pump. The negative pressure calibration sensor will continue to sense the negative pressure. When the pressure value of the negative pressure sensor is the same as the set pressure value, blockage is prevented.

[0009] Preferably, the sampling and impurity removal unit includes a heating impurity remover, a zero drift elimination device, an outlier detection eliminator and an optimized impurity removal algorithm; the zero drift elimination device is connected to the input and output ends of the heating impurity remover, the outlier detection eliminator is welded to the input end of the zero drift elimination device, and the optimized impurity removal algorithm is connected to the input end of the outlier detection eliminator, and the processing speed of the heating impurity remover is higher than that of the zero drift elimination device.

[0010] In the present technical solution, when passing through the acquisition module, the acquisition module is used to collect the phosphine gas data in the sampled gas, and the sampling and impurity removal unit can remove impurities by heating the impurity remover, and eliminate the distinguishing features of the sampling data by the zero drift elimination device. Finally, there is an optimized impurity removal algorithm to optimize the collected data, and the data collection is more accurate.

[0011] Preferably, the multiple proofreading unit includes an outlier identification machine, and the output end of the outlier identification machine is connected to a multi-source data comparator, the output end of the multi-source data comparator is communicatively connected to a calibration algorithm model, and the output end of the calibration algorithm model is connected to an iterative optimization host. The storage module includes a network encrypted cloud disk, a storage encrypted hard disk 1, and a storage encrypted hard disk 2, and the network encrypted cloud disk, the storage encrypted hard disk 1, and the storage encrypted hard disk 2 are stored synchronously. The storage order of the storage encrypted hard disk 1 is superior to the storage order of the storage encrypted hard disk 2, and the storage capacity of the storage encrypted hard disk 1 and the storage encrypted hard disk 2 is the same.

[0012] In the present technical solution, the calibration module is used to perform data proofreading processing on the data, and then the outlier identification machine on the multiple proofreading units is used to identify the outliers, wherein the calibration algorithm model can proofread the algorithm, and the transmission module transmits the optimized data, wherein the main transmission means include forwarding the data, transmitting it to the remote server through the MQTT protocol, and the storage module stores the data, mainly realizing network encryption processing by the network encrypted cloud disk on the storage module, and realizing storage encryption processing by storing encrypted hard disk one. Once the network encrypted cloud disk is full, it will continue to be supplemented by encrypted storage through storage encrypted hard disk two.

[0013] Technical effects and advantages of the present invention: The present invention uses a suction sensor on a pump suction anti-blocking switching unit to sense the suction of the pump. When the suction is low for more than five minutes, an alarm is sounded through a time alarm, and the unblocking electric cylinder pushes the suction of each pump to dredge it. After unblocking, the suction generated by the pump, the pressure value of the negative pressure sensor is the same as the set pressure value, so blockage is prevented, and it is safer to use. The sampling and impurity removal unit can perform heating and impurity removal through a heating impurity remover, and a zero drift eliminater eliminates the distinguishing features of the sampling data, and an abnormal value detection eliminator eliminates abnormal values, so that online monitoring of phosphine is more accurate.

[0014] The present invention realizes the recognition of outliers through an outlier recognition machine on multiple proofreading units, and a multi-source data comparator performs diversified comparison on the data, wherein the calibration algorithm model can proofread the algorithm, thereby optimizing the collected data and ensuring that the collected data is more accurate.

[0015] The present invention stores data through a storage module, and mainly implements network encryption processing through a network encrypted cloud disk on the storage module, and implements storage encryption processing through a first storage encrypted hard disk. Once the network encrypted cloud disk is full, encrypted storage is continued to be replaced through a second storage encrypted hard disk. In this way, storage is more accurate in use, and precise data collection and monitoring are achieved, with better monitoring accuracy.

[0016] The above multiple effects interact with each other. First, the pressure value of the negative pressure sensor is the same as the set pressure value. At the same time, the abnormal value detection eliminator eliminates the abnormal value. Secondly, the calibration algorithm model can calibrate the algorithm, thereby optimizing the collected data. Finally, if the network encrypted cloud disk is full, it will continue to be encrypted and stored through the encrypted hard disk. This storage is more accurate and realizes accurate data collection and monitoring. In summary, not only can the pump suction part avoid blockage during the collection and use process, but also the sampling data collection is finely proofread and processed, and multiple proofreading can be achieved, greatly improving the accuracy of collection and monitoring.

The clearing electric cylinder 12 will push and clear the suction of each pump. After clearing, the suction generated by the pump can continue to be sensed by the negative pressure calibration sensor 13. When the pressure value of the negative pressure sensor is the same as the set pressure value, blockage is prevented.

[0031] The working principle of the pump-suction type phosphine online monitoring system of the present invention is as follows: Step 1: When switching the pump suction anti-blocking, the suction sensor 10 on the pump suction anti-blocking switching unit 7 on the input end of the pump suction module 1 senses the suction of the pump. When the suction is low for more than five minutes, the time alarm 11 alarms and the dredging electric cylinder 12 is started. The dredging electric cylinder 12 pushes the suction of each pump to dredge. After dredging, the suction generated by the pump can continue to sense the negative pressure by the negative pressure calibration sensor 13. When the pressure value of the negative pressure sensor is the same as the set pressure value, blockage is prevented, and it is safer to use. And the pump suction module 1 allows the pump to sample the gas in the environment or materials at regular intervals.
