[0002] Hydrogen production through water electrolysis is a green energy technology that generates hydrogen and oxygen by electrolyzing water.

The electrolyzer, as the core component of water electrolysis hydrogen production equipment, directly determines the hydrogen production efficiency and the safety of the equipment.

[0003] However, existing electrolyzer testing methods typically only detect the total voltage signal of the electrolyzer. Since electrolyzers usually contain hundreds of individual electrolysis cells, abnormal voltage changes in a single cell are often difficult to reflect in the total voltage signal.

Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0021] The following description, in conjunction with the accompanying drawings, details an electrolytic cell detection system, method, device, electronic equipment, and storage medium provided in this application, through specific embodiments and application scenarios.

[0022] Figure 1 This is a schematic diagram of the architecture of an electrolytic cell detection system provided in an embodiment of this application, as shown below. Figure 1 As shown, the electrolytic cell detection system includes a DCS (Distributed Control System) upper-level monitoring system and a small cell voltage detection device, wherein the upper-level monitoring system and the small cell voltage detection device communicate via a 485 bus.

[0023] The small cell voltage detection device is used to collect the digital signal of the small cell voltage of at least one electrolytic cell in the electrolytic cell and send the digital signal of the small cell voltage of at least one electrolytic cell to the upper monitoring system.

[0024] The upper-level monitoring system is used to receive the digital voltage signal of at least one electrolysis cell. For any electrolysis cell, the digital voltage signal of the electrolysis cell is compared with a preset voltage threshold. Based on the comparison result of the digital voltage signal of the electrolysis cell and the voltage threshold, it is determined whether to alarm the electrolysis cell and whether to control the electrolysis cell to stop operation.

[0025] In some embodiments of this application, the electrolytic cell testing system adopts an explosion-proof design, and all modules in the electrolytic cell testing system are installed in an explosion-proof junction box. To reduce the amount of cabling from the electrolytic cell to the electrolytic cell testing system, the entire electrolytic cell testing system can be installed locally next to the electrolytic cell being tested. Detection lines are output from the electrolytic cell testing system and connected to the electrode plates of the electrolytic cell being tested in the electrolytic cell to measure the cell voltage.

[0026] The DCS (Distributed Control System) is the control system for the water electrolysis hydrogen production equipment. The electrolyzer is the core component of the water electrolysis hydrogen production equipment, and it includes at least one electrolysis chamber.

[0027] The digital voltage signal of at least one electrolytic cell in the electrolytic cell is acquired by a cell voltage detection device. After the cell voltage detection device acquires the digital voltage signal of at least one electrolytic cell in the electrolytic cell, it transmits the digital voltage signal of at least one electrolytic cell to the upper monitoring system via a 485 bus.

[0028] After receiving the digital voltage signal of at least one electrolysis cell from the cell voltage detection device, the supervisory control system compares the digital voltage signal of any electrolysis cell with a preset voltage threshold. Based on the comparison result, it determines whether to issue an alarm for the electrolytic cell and whether to control the electrolytic cell to stop operation.

[0029] This application acquires the digital voltage signal of the electrolytic cells in the electrolytic cell using a small-cell voltage detection device, and compares the digital voltage signal of the electrolytic cells with a preset voltage threshold through a host monitoring system. This not only detects the digital voltage signal of the electrolytic cells in the electrolytic cell, enabling the detection of abnormal operating conditions of the electrolytic cells, but also triggers an alarm when the digital voltage signal of the electrolytic cells is abnormal, so that timely measures can be taken, or the electrolytic cell can be stopped to avoid further damage to the electrolytic cell. This effectively prevents and controls abnormal operating conditions of the electrolytic cell.

[0030] Furthermore, in some embodiments of this application, the supervisory control system is also used to control the electrolytic cell to stop operating if the digital signal of the cell voltage of the electrolytic cell is less than a first voltage threshold.

[0031] The upper-level monitoring system is also used to alarm the electrolytic cell if the digital signal of the cell voltage of the electrolytic cell is greater than or equal to the first voltage threshold and the digital signal of the cell voltage of the electrolytic cell is less than the second voltage threshold, wherein the first voltage threshold is less than the second voltage threshold.

[0032] The upper-level monitoring system is also used to alarm the electrolytic cell if the digital signal of the cell voltage of the electrolytic cell is greater than the third voltage threshold and less than or equal to the fourth voltage threshold, wherein the third voltage threshold is less than the fourth voltage threshold.

[0033] The supervisory control system is also used to control the electrolytic cell to stop operating if the digital signal of the cell voltage in the electrolysis cell is greater than the fourth voltage threshold.

[0034] In some embodiments of this application, the voltage threshold includes a first voltage threshold, a second voltage threshold, a third voltage threshold, and a fourth voltage threshold, wherein the first voltage threshold can be 1V, the second voltage threshold can be 1.4V, the third voltage threshold can be 2.3V, and the fourth voltage threshold can be 2.6V.

[0035] In a normally operating electrolyzer, the voltage in each electrolysis cell is typically between 1.5V and 2.2V. Excessive voltage may indicate a lack of circulating water or blockage in the cell, which is dangerous. Conversely, insufficient voltage may indicate a short circuit between the electrodes, which is even more dangerous. Therefore, once hydrogen production begins in the electrolyzer, the supervisory control system compares the digital voltage signal of each cell in real time with a preset voltage threshold, triggering an alarm or stopping the electrolyzer.

[0036] Specifically, if the upper-level monitoring system detects that the digital signal of the cell voltage in the electrolysis cell is less than the first voltage threshold, the upper-level monitoring system will control the electrolysis cell to stop operating.

[0037] If the upper-level monitoring system detects that the digital signal of the cell voltage in the electrolysis cell is greater than or equal to the first voltage threshold and less than the second voltage threshold, the upper-level monitoring system will issue an alarm for the electrolysis cell.

[0038] If the supervisory control system detects that the digital signal of the cell voltage in the electrolysis cell is greater than the third voltage threshold and less than or equal to the fourth voltage threshold, the supervisory control system will issue an alarm for the electrolysis cell.

[0039] If the supervisory control system detects that the digital signal of the cell voltage in the electrolysis cell is greater than the fourth voltage threshold, the supervisory control system will control the electrolysis cell to stop operating.

[0040] This application enables more detailed division of voltage ranges by setting multiple voltage thresholds (e.g., a first voltage threshold, a second voltage threshold, a third voltage threshold, and a fourth voltage threshold). This allows for different response measures to be taken based on the different voltage ranges of the digital voltage signal of the electrolysis cell, thus achieving refined control of the electrolytic cell's operating status.

[0041] Furthermore, in some embodiments of this application, at least one analog input detection module is used to acquire the digital signal of the cell voltage of at least one electrolysis cell and send the digital signal of the cell voltage of at least one electrolysis cell to the communication relay circuit board.

[0042] The communication relay circuit board is used to receive the digital voltage signal of at least one electrolysis cell and send the digital voltage signal of at least one electrolysis cell to the upper monitoring system.

[0043] In some embodiments of this application, the cell voltage detection device includes a communication relay circuit board and at least one AI (Analog Input) detection module. The communication relay circuit board communicates with at least one AI detection module via a 485 bus. The number of AI detection modules can be four, and one AI detection module can collect the cell voltage digital signals of four electrolytic cells.

[0044] The AI ​​detection module is directly connected to the electrodes of the electrolysis chamber, which consists of an anode and a cathode. After connection, the AI ​​detection module can detect the voltage difference between the anode and cathode. This voltage difference is the analog voltage signal of the electrolysis chamber. To enable communication transmission of the chamber voltage, the AI ​​detection module converts the acquired analog voltage signal into a digital voltage signal.

[0045] At least one AI detection module can acquire the digital signal of the cell voltage of at least one electrolysis cell and send the digital signal of the cell voltage of at least one electrolysis cell to the communication relay circuit board via the 485 bus.

[0046] The communication relay circuit board can function as a substation, communicating with the DCS's upper-level monitoring system via a 485 bus. The communication relay circuit board can transmit the digital signal of the cell voltage of at least one electrolysis cell to the upper-level monitoring system via the 485 bus.

[0047] The communication relay circuit board can also serve as the master station, with the four AI detection modules acting as slave stations. The communication relay circuit board communicates with each of the four AI detection modules via a 485 bus. The communication relay circuit board reads the digital signal of the electrolysis chamber voltage collected by each AI detection module via the 485 bus.

[0048] Furthermore, since RS-485 communication uses a polling mechanism, a large number of AI detection modules can lead to increased communication latency. If the DCS's supervisory control system directly communicates with the AI ​​detection modules via RS-485, the signal refresh time will also be prolonged. Therefore, a communication relay circuit board is installed. This circuit board collects the digital voltage signals of at least one electrolysis cell from all AI detection modules and sends them to the DCS's supervisory control system to improve communication efficiency.

[0049] This application uses a communication relay circuit board to uniformly send the digital signal of the cell voltage of at least one electrolysis cell to the upper monitoring system, which can significantly improve the transmission efficiency of the digital signal of the cell voltage of the electrolysis cell.

[0050] Furthermore, in some embodiments of this application, the power module is used to collect the voltage of the power supply of the communication relay circuit board and convert the voltage of the power supply of the communication relay circuit board into a first voltage, wherein the first voltage is less than the voltage of the power supply of the communication relay circuit board.

[0051] The voltage regulator chip is used to convert the first voltage into a second voltage, which is used as the power supply voltage for the main control chip. The second voltage is less than the first voltage.

[0052] In some embodiments of this application, the communication relay circuit board includes a power supply circuit and a main control chip, such as... Figure 2 As shown, the power supply circuit includes a power supply module and a voltage regulator chip. The power supply module is URB2405YMD-10WR3, and the voltage regulator chip is AMS1117-3.3.

[0053] like Figure 3As shown, the main control chip used in the communication relay circuit board is the STM32F103RCT6. The STM32F103RCT6 is a 32-bit microcontroller with 256KB of program memory, 48KB of RAM, a processing speed of 72MHz, a voltage requirement of 2V~3.6V, an operating temperature of -40℃~85℃, multiplexed GPIO pins, and supports J-Link SWD for program downloading and online debugging. In some embodiments of this application, the STM32F103RCT6's USART (Universal Synchronous Asynchronous Receiver / Transmitter), SPI (Serial Peripheral Interface), ADC (Analog to Digital Converter), GPIO_OUT (General Purpose Input / Output Interface - Output Mode), GPIO_IN (General Purpose Input / Output Interface - Input Mode), and Timer functions are mainly used.

[0054] The communication relay circuit board uses a total of three power supply voltages: the power supply voltage of the communication relay circuit board, the first voltage, and the second voltage. The power supply voltage of the communication relay circuit board is 24V, the first voltage is 5V, and the second voltage is 3.3V. These three power supply voltages can supply different components on the communication relay circuit board respectively.

[0055] like Figure 2 As shown, the communication relay circuit board uses a 24V DC power supply. The power module URB2405YMD-10WR3 converts the 24V DC to 5V DC, and then the AMS1117-3.3 voltage regulator converts the 5V DC to 3.3V DC. The main control chip in the communication relay circuit board requires a 3.3V power supply; therefore, the converted 3.3V DC is used to power the main control chip, ensuring its normal operation and thus enabling the entire communication relay circuit board to function correctly.

[0056] This application converts the power supply voltage of the communication relay circuit board into a second voltage in stages to serve as the power supply voltage for the main control chip. This ensures that the main control chip in the communication relay circuit board can obtain a stable power supply voltage under different operating conditions, thereby improving the working stability of the main control chip.

[0057] Furthermore, in some embodiments of this application, a dual power supply circuit is used to power a voltage follower circuit.

[0058] The voltage follower circuit is used to acquire the analog voltage signal of at least one electrolytic cell, and to preprocess the analog voltage signal of at least one electrolytic cell to obtain the processed analog voltage signal of at least one electrolytic cell.

[0059] In some embodiments of this application, the AI ​​detection module is provided with a signal isolation conversion circuit, wherein the signal isolation conversion circuit includes a dual power supply circuit and a voltage follower circuit.

[0060] like Figure 4 As shown, the dual power supply circuit receives 5V DC input, which, after passing through the power module A0512S, outputs ±12V. The ±12V power supplies the voltage follower circuit.

[0061] After acquiring the analog voltage signal of at least one electrolytic cell, the voltage follower circuit preprocesses the analog voltage signal of at least one electrolytic cell to obtain the processed analog voltage signal of at least one electrolytic cell. By setting up the voltage follower circuit, it achieves the functions of increasing input impedance, buffering, isolation, and filtering.

[0062] This application provides power to the voltage follower circuit via a dual-power supply circuit, ensuring a stable voltage supply under various operating conditions. Furthermore, this application preprocesses the analog voltage signal of at least one electrolytic cell using the voltage follower circuit, removing noise and interference from the analog voltage signal of at least one electrolytic cell, improving the signal quality, and making the processed analog voltage signal of at least one electrolytic cell more stable and reliable.

[0063] Furthermore, in some embodiments of this application, the filtering circuit is used to filter the analog voltage signal of at least one electrolytic cell to obtain the filtered analog voltage signal of at least one electrolytic cell.

[0064] The operational amplifier chip is used to amplify the filtered analog voltage signal of at least one electrolytic cell to obtain the processed analog voltage signal of at least one electrolytic cell.

[0065] In some embodiments of this application, the voltage follower circuit includes a filter circuit composed of R2 and C1 and an operational amplifier chip LM358.

[0066] like Figure 4As shown, IN+ and IN- are the analog voltage signals of at least one electrolytic cell with an input voltage of 4-20mA. The analog voltage signals of at least one electrolytic cell are converted into voltage signals by a high-precision resistor JR1, and then filtered by an RC low-pass filter circuit of R2 and C1. Substituting the resistance value of R2 (10K) and the capacitance value of C1 (10nF) into formula (1), the cutoff frequency can be calculated to be approximately 1.59KHz. The filtered analog voltage signals of at least one electrolytic cell are amplified by an operational amplifier chip LM358 and then output as the processed analog voltage signals of at least one electrolytic cell.

[0067] Formula (1) in, The cutoff frequency, It is a mathematical constant, approximately 3.1415926. For resistance, It is a capacitor.

[0068] This application uses a filtering circuit to filter the analog voltage signal of at least one electrolytic cell, effectively removing noise and interference components and improving the signal quality. Furthermore, this application uses an operational amplifier chip to amplify the filtered analog voltage signal of at least one electrolytic cell, increasing its amplitude and facilitating subsequent signal analysis and processing.

[0069] Furthermore, in some embodiments of this application, the analog-to-digital converter chip is used to convert the processed analog voltage signal of at least one electrolytic cell into a digital voltage signal of at least one electrolytic cell if it receives a chip select signal output by the main control chip.

[0070] In some embodiments of this application, such as Figure 3 As shown, the AI ​​detection module includes an analog-to-digital converter chip, which uses the MCP3208.

[0071] The MCP3208 analog-to-digital converter (ADC) chip is a 12-bit, 8-input channel successive approximation ADC with a sampling rate of up to 100kHz. It features low power consumption, small linear error, and a standard SPI serial output for communication with the STM32F103RCT6 controller chip. The STM32F103RCT6 controller chip can output a chip select signal, which can be used to activate different MCP3208 ADC chips, significantly expanding the number of ADC channels available on the STM32F103RCT6 controller chip.

[0072] Specifically, for any AI detection module, if the analog-to-digital converter chip in the AI ​​detection module receives the chip select signal output by the main control chip, the analog-to-digital converter chip in the AI ​​detection module will perform signal conversion on the processed analog signal of the cell voltage of at least one electrolytic cell obtained by the AI ​​detection module to obtain the digital signal of the cell voltage of at least one electrolytic cell.

[0073] This application uses an analog-to-digital converter chip to convert the processed analog voltage signal of at least one electrolytic cell into a digital voltage signal of at least one electrolytic cell, thereby realizing the conversion from analog signal to digital signal, which facilitates subsequent digital signal transmission, processing and analysis.

[0074] See Figure 5 This application also provides a flowchart of a method for detecting an electrolytic cell, the method comprising: Step 501: Acquire the digital signal of the cell voltage of at least one electrolytic cell in the electrolytic cell.

[0075] Step 502: For any electrolysis cell, compare the digital signal of the cell voltage of the electrolysis cell with a preset voltage threshold.

[0076] Step 503: Based on the comparison result between the digital signal of the cell voltage of the electrolysis cell and the voltage threshold, determine whether to alarm the electrolysis cell and whether to control the electrolysis cell to stop operation.

[0077] In some embodiments of this application, a cell voltage detection device acquires the digital signal of the cell voltage of at least one electrolytic cell in the electrolytic cell. After the cell voltage detection device acquires the digital signal of the cell voltage of at least one electrolytic cell in the electrolytic cell, the cell voltage detection device transmits the digital signal of the cell voltage of at least one electrolytic cell to the upper monitoring system via a 485 bus.

[0078] After receiving the digital voltage signal of at least one electrolysis cell from the cell voltage detection device, the supervisory control system compares the digital voltage signal of any electrolysis cell with a preset voltage threshold. Based on the comparison result, it determines whether to issue an alarm for the electrolytic cell and whether to control the electrolytic cell to stop operation.

[0079] This application acquires the digital voltage signal of the electrolytic cells in the electrolytic cell using a small-cell voltage detection device, and compares the digital voltage signal of the electrolytic cells with a preset voltage threshold through a host monitoring system. This not only detects the digital voltage signal of the electrolytic cells in the electrolytic cell, enabling the detection of abnormal operating conditions of the electrolytic cells, but also triggers an alarm when the digital voltage signal of the electrolytic cells is abnormal, so that timely measures can be taken, or the electrolytic cell can be stopped to avoid further damage to the electrolytic cell. This effectively prevents and controls abnormal operating conditions of the electrolytic cell.

[0080] Furthermore, in some embodiments of this application, the electrolytic cell detection system is designed with three data viewing methods, including: 1) A local display screen is provided, which is connected to the communication relay circuit board, so that the currently acquired cell voltage digital signal of the electrolytic cell can be viewed on the screen of the local display screen. 2) The acquired cell voltage digital signal of the electrolytic cell is viewed at the DCS end through data communication with the DCS. 3) The communication relay circuit board is debugged through a program debugging download cable (a hardware tool used to debug the circuit board), and the cell voltage digital signal of the electrolytic cell read by the communication relay circuit board is viewed on the debugging computer.

[0081] Furthermore, in some embodiments of this application, the electrolytic cell detection system supports the ModbsuRTU protocol of the 485 communication interface, and also supports the ModbusTCP protocol of the Ethernet communication interface.

[0082] Furthermore, in some embodiments of this application, a sensor address table can be pre-set. This address table refers to the correspondence between Modbus addresses and the digital voltage signals of the electrolysis cells. The sensor address table is sent to the DCS controller, who can then query the corresponding digital voltage signal of the electrolysis cell based on the Modbus address.

The electrolytic cell detection module 603 is used to determine whether to alarm the electrolytic cell and whether to control the electrolytic cell to stop operation based on the comparison result between the digital signal of the cell voltage and the voltage threshold.
