Description

Technical Field

[0001] The present invention relates to the technical field of online monitoring and control, in particular to an online monitoring and control system based on the Internet. Background Art

[0002] An electrolyte is a liquid containing ions that conducts electric current in a battery or electrolytic cell. It plays a key role in the electrochemical process, allowing electrons to complete the circuit by migrating between electrodes.

[0003] However, in the prior art, the electrolyte delivery control cannot determine the electrolyte balance monitoring requirements based on real-time delivery, which reduces the delivery control efficiency. In addition, during the current electrolyte filling process, electrolyte barrels are stored in centralized liquid supply workshops, and the electrolyte is transported by liquid supply pipelines throughout the process. It is impossible to monitor the remaining status of the electrolyte in the barrels in real time, and it is also impossible to handle and replace the electrolyte barrels in time.

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

[0005] The purpose of the present invention is to solve the above-mentioned problems and to provide an Internet-based online monitoring and control system.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] An Internet-based online monitoring and control system includes a cloud, the cloud is communicatively connected to a monitoring demand analysis unit and a supply deviation analysis unit, and the cloud is also communicatively connected to a control system;

[0008] The monitoring demand analysis unit performs supply analysis on the electrolyte supply pipeline, generates a monitoring high demand signal or a supply stability signal through data collection and analysis, and sends it to the cloud;

[0009] The supply deviation analysis unit analyzes the supply deviation of each liquid supply pipeline, generates a supply high deviation signal or a supply low deviation signal through data collection and analysis, and sends it to the cloud;

[0010] After receiving the supply high deviation signal or monitoring high demand signal, the cloud generates an execution instruction to the control system.

[0011] As a preferred embodiment of the present invention, the monitoring demand analysis unit operates as follows:

[0012] The increase span of the number of liquid supply pipelines where the actual liquid supply speed deviates from the set speed in the same liquid supply cycle, and the increase span of the frequency when the liquid supply pipelines corresponding to different liquid supply cycles are terminated and the electrolyte in the pipeline is re-delivered and supplied are collected, and compared with the quantity increase threshold and the frequency increase span threshold respectively.

[0013] As a preferred embodiment of the present invention, if the number of liquid supply pipelines whose actual liquid supply speed deviates from the set speed in the same liquid supply cycle increases by a span exceeding a number increase threshold, or the frequency increase span of the corresponding liquid supply pipelines in different liquid supply cycles suspending and re-delivering the electrolyte in the pipeline exceeds a frequency increase span threshold, a monitoring high demand signal is generated;

[0014] If the increase span of the number of liquid supply pipelines where the actual liquid supply speed deviates from the set speed within the same liquid supply cycle does not exceed the number increase threshold, and the frequency increase span of the liquid supply pipelines corresponding to different liquid supply cycles terminating and re-delivering the electrolyte in the pipeline does not exceed the frequency increase span threshold, a supply stability signal is generated.

[0015] As a preferred embodiment of the present invention, the operation process of the supply deviation analysis unit is as follows:

[0016] The deviation value between the real-time single set flow mean and the actual flow mean during the liquid supply process of the liquid supply pipeline, and the maximum increase span value of the liquid supply loss during the continuous supply stage during the liquid supply process of the liquid supply pipeline are collected, and compared with the mean deviation threshold and the maximum increase span threshold of the loss respectively.

[0017] As a preferred embodiment of the present invention, if the deviation between the real-time single set flow rate mean and the actual flow rate mean during the liquid supply process of the liquid supply pipeline exceeds the mean deviation threshold, or the maximum increase span value of the liquid supply loss in the continuous supply stage during the liquid supply process of the liquid supply pipeline exceeds the maximum increase span threshold of the loss, a supply high deviation signal is generated;

[0018] If the deviation between the real-time single set flow mean and the actual flow mean during the liquid supply process of the liquid supply pipeline does not exceed the mean deviation threshold, and the maximum increase span value of the liquid supply loss during the continuous supply stage during the liquid supply process of the liquid supply pipeline does not exceed the maximum increase span threshold of the loss, a supply low deviation signal is generated.

[0019] As a preferred embodiment of the present invention, the control system includes a liquid level meter and an ID card. The liquid level meter monitors the liquid level of the electrolyte, and the ID card resets the liquid level meter state. The liquid level meter monitors the liquid level of the electrolyte and transmits the data to the cloud through a wireless transmission terminal, which is monitored in real time by a monitoring device. The wireless receiving terminal has a data processing function, and controls the PLC by receiving the liquid level meter data to achieve the purpose of controlling the equipment.

[0020] As a preferred embodiment of the present invention, after the control system receives the signal transmitted by the liquid level meter through GPIO, it converts the signal into a signal and uploads it to the cloud server through the data transmission MQTT protocol or TCP protocol; the cloud server receives the signal and processes it, and transmits the information to the monitoring device to give an alarm prompt; and the employee performs processing operations after receiving the alarm prompt.

[0021] As a preferred embodiment of the present invention, the cloud server receives and processes the signal, and sends a shutdown waiting signal to the control system. The control system receives the shutdown signal, controls the device PLC program through GPIO, and performs the equipment shutdown waiting. After receiving the alarm prompt, the employee performs the processing operation and replaces the electrolyte barrel. After the replacement is completed, the monitoring device is reset, and the reset information is uploaded to the cloud.

[0022] As a preferred embodiment of the present invention, the cloud receives the reset information and sends a replacement completion signal to the control system to restore the device action; the control system receives the cloud signal and controls the device PLC program through GPIO to perform the device liquid filling action, and extracts the electrolyte from the centralized liquid supply pipeline to the liquid injection machine;

[0023] Through GPIO control of the equipment PLC program, after the equipment starts to fill with liquid, the electrolyte enters the electrolyte pipeline from the ton barrel, and the liquid level meter starts to detect whether there is electrolyte to make a judgment; the liquid level meter detects the presence of electrolyte and transmits the signal to the wireless receiving terminal. The wireless receiving terminal controls the PLC to make the equipment send out an alarm prompt. After the employee confirms, he swipes the ID card. The wireless receiving terminal reads the ID card through RFID, and combines the liquid level meter detection signal to form a double judgment that the liquid supply is completed.

[0024] As a preferred embodiment of the present invention, after the wireless receiving terminal has completed the liquid supply through double determination, it transmits a signal to the cloud, and the cloud eliminates the alarm prompt of the monitoring equipment, and the alarm is eliminated normally; it transmits a signal to the wireless receiving terminal, and the wireless receiving terminal controls the PLC to allow production.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] In the present invention, supply analysis of the liquid supply pipeline is used to infer whether the current liquid supply network needs to perform pipeline monitoring immediately, so as to prevent unnecessary costs caused by inaccurate real-time supply volume in the previous period and simultaneous surplus monitoring. It can also avoid that when the real-time supply volume statistics of the current liquid supply network are inaccurate, the surplus monitoring cannot be performed in time, which reduces the supply efficiency and avoids affecting the liquid supply progress of the liquid supply pipeline; the supply deviation of each liquid supply pipeline is analyzed, and it is inferred whether there is a liquid supply deviation in the liquid supply pipeline in the supply network, so that errors in the liquid supply volume record lead to a decrease in the real-time monitoring efficiency of the electrolyte barrel, which is easy to cause untimely liquid supply or excessive electrolyte storage, thereby reducing the actual liquid supply efficiency of the liquid supply pipeline.

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.

[0031] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0032] See also Figure 1 As shown, an Internet-based online monitoring and control system includes a cloud, the cloud is connected to a monitoring demand analysis unit and a supply deviation analysis unit, and the cloud is also connected to a control system, wherein the control system includes a wireless receiving terminal, GPIO, PLC, monitoring equipment, GPIO, liquid level card, RFID and ID card; Figure 2 As shown;

[0033] When one or more electrolyte supply pipelines are being supplied, the cloud generates a monitoring demand analysis signal and sends the monitoring demand analysis signal to the monitoring demand analysis unit. After receiving the monitoring demand analysis signal, the monitoring demand analysis unit performs supply analysis on the electrolyte supply pipeline, and infers whether the current supply network needs to perform pipeline monitoring immediately through the supply analysis of the supply pipeline, thereby preventing the previous supply from generating unnecessary costs while performing surplus monitoring while the real-time supply volume is accurate. It can also avoid the inability to perform surplus monitoring in a timely manner when the real-time supply volume statistics of the current supply network are inaccurate, thereby reducing the supply efficiency and avoiding affecting the supply progress of the supply pipeline;

[0034] The increase span of the number of liquid supply pipelines whose actual liquid supply speed deviates from the set speed in the same liquid supply cycle is obtained, and the frequency increase span of the liquid supply pipelines corresponding to different liquid supply cycles being stopped and the electrolyte in the pipeline being re-delivered and supplied is obtained, and the increase span of the number of liquid supply pipelines whose actual liquid supply speed deviates from the set speed in the same liquid supply cycle and the frequency increase span of the liquid supply pipelines corresponding to different liquid supply cycles being stopped and the electrolyte in the pipeline being re-delivered and supplied are compared with the quantity increase threshold and the frequency increase span threshold respectively:

[0035] If the number of liquid supply pipelines whose actual liquid supply speed deviates from the set speed in the same liquid supply cycle exceeds the number increase threshold, or the frequency increase span of the corresponding liquid supply pipelines in different liquid supply cycles being suspended and the electrolyte in the pipeline being re-delivered for supply exceeds the frequency increase span threshold, it is inferred that the liquid supply network needs to perform surplus monitoring, generate a monitoring high demand signal and send the monitoring high demand signal to the cloud;

[0036] If the increase span of the number of liquid supply pipelines where the actual liquid supply speed deviates from the set speed in the same liquid supply cycle does not exceed the number increase threshold, and the frequency increase span of the corresponding liquid supply pipelines in different liquid supply cycles suspending and re-delivering the electrolyte in the pipeline does not exceed the frequency increase span threshold, then the real-time supply quantity of the liquid supply network is inferred to be determined, a supply stability signal is generated and sent to the cloud;

[0037] The cloud generates a supply deviation analysis signal and sends it to the supply deviation analysis unit. After receiving the supply deviation analysis signal, the supply deviation analysis unit analyzes the supply deviation of each liquid supply pipeline, and infers whether there is a liquid supply deviation in the liquid supply pipeline in the supply network, so that errors in the liquid supply volume record cause the real-time monitoring efficiency of the electrolyte barrel to decrease, which is easy to cause untimely liquid supply or excessive electrolyte storage, thereby reducing the actual liquid supply efficiency of the liquid supply pipeline;

[0038] The deviation value between the mean of the real-time single set flow rate and the mean of the actual flow rate during the liquid supply process of the liquid supply pipeline is collected, and the maximum increase span value of the liquid supply loss in the continuous supply stage during the liquid supply process of the liquid supply pipeline is collected. The deviation value between the mean of the real-time single set flow rate and the mean of the actual flow rate during the liquid supply process of the liquid supply pipeline and the maximum increase span value of the liquid supply loss in the continuous supply stage during the liquid supply process of the liquid supply pipeline are compared with the mean deviation threshold and the maximum increase span threshold of the loss respectively:

[0039] If the deviation between the real-time single set flow rate mean and the actual flow rate mean during the liquid supply process of the liquid supply pipeline exceeds the mean deviation threshold, or the maximum increase span value of the liquid supply loss during the continuous supply stage during the liquid supply process of the liquid supply pipeline exceeds the maximum increase span threshold of the loss, it is inferred that the supply deviation analysis of the current liquid supply pipeline is abnormal, and a supply high deviation signal is generated and sent to the cloud;

[0040] If the deviation between the real-time single set flow rate mean and the actual flow rate mean during the liquid supply process of the liquid supply pipeline does not exceed the mean deviation threshold, and the maximum increase span value of the liquid supply loss during the continuous supply stage during the liquid supply process of the liquid supply pipeline does not exceed the maximum increase span threshold of the loss, it is inferred that the supply deviation analysis of the current liquid supply pipeline is normal, and a supply low deviation signal is generated and sent to the cloud;

[0041] After receiving the supply high deviation signal or monitoring high demand signal, the cloud generates an execution instruction to the control system. The control system includes a liquid level meter and an ID card. The liquid level meter monitors the liquid level of the electrolyte, and the ID card resets the liquid level meter status; the liquid level meter monitors the electrolyte level and transmits the data to the cloud through a wireless transmission terminal, which is monitored in real time by the monitoring equipment. The wireless receiving terminal has a data processing function, and controls the PLC by receiving the liquid level meter data to achieve the purpose of controlling the equipment; the liquid level meter has the function of real-time monitoring of the liquid level in the electrolyte supply pipeline and transmitting it to the control system through GPIO;

[0042] After the control system receives the signal transmitted by the liquid level meter through GPIO, it converts it into a signal and uploads it to the cloud server through the data transmission MQTT protocol or TCP protocol; the cloud server receives the signal and processes it, and transmits it to the monitoring device through information to give an alarm prompt; after receiving the alarm prompt, the employee performs the processing operation;

[0043] The cloud server receives the signal and processes it, and sends a shutdown waiting signal to the control system. The control system receives the shutdown signal and controls the device PLC program through GPIO to make the device shut down and wait. After receiving the alarm prompt, the employee performs the processing operation and replaces the electrolyte barrel. After the replacement is completed, the monitoring device is reset and the reset information is uploaded to the cloud.

[0044] The cloud receives the reset information and sends a replacement completion signal to the control system to restore the equipment operation; the control system receives the cloud signal and controls the equipment PLC program through GPIO to perform the equipment liquid filling action, and extracts the electrolyte from the centralized liquid supply pipeline to the liquid injection machine; after the equipment liquid filling action is performed by controlling the equipment PLC program through GPIO, the electrolyte enters the electrolyte pipeline from the ton barrel, and the liquid level meter begins to detect the presence of electrolyte for judgment; the liquid level meter detects the presence of electrolyte and transmits the signal to the wireless receiving terminal, which controls the PLC to make the equipment issue an alarm prompt. After the employee confirms, he swipes the ID card, and the wireless receiving terminal reads the ID card through RFID, combining the liquid level meter detection signal to form a double judgment that the liquid supply is completed;

[0045] After the wireless receiving terminal has completed the liquid supply through double judgment, it transmits the signal to the cloud, and the cloud eliminates the alarm prompt of the monitoring equipment, and the alarm is eliminated normally. The signal is transmitted to the wireless receiving terminal, and the wireless receiving terminal controls the PLC to allow production.
