Description

Technical Field

[0001] The present disclosure relates to the technical field of ship power supply, and in particular to an ambient hydrogen content regulating system. Background Art

[0002] With the development of power electronics technology, uninterruptible power supply systems (UPS) are widely used in various important occasions that require continuous power supply, such as data centers, medical equipment, communication base stations, etc. In order to ensure the continuity and stability of power supply, uninterruptible power supply systems usually use battery packs as backup power supplies, which can seamlessly switch to battery power supply mode when the main power supply fails, thereby maintaining the normal operation of the load.

[0003] However, the battery packs in the uninterruptible power supply system, especially those using lead-acid batteries or hydrogen fuel cells, may produce hydrogen during the charging and discharging process. Hydrogen is a flammable and explosive gas, and there are safety hazards when its concentration reaches a certain threshold. Therefore, for the safe operation of the uninterruptible power supply system, it is crucial to monitor and control the hydrogen concentration. At present, the monitoring of hydrogen content inside the uninterruptible power supply system and the surrounding environment is mainly achieved through manual regular inspections or the installation of simple hydrogen detection devices. However, these methods have some shortcomings:

[0004] Manual inspection is inefficient and may result in omissions: Due to the long manual inspection cycle, it is impossible to monitor the changes in hydrogen concentration in real time. Simple detection devices have limited functions: Existing detection devices can only send out alarm signals, but cannot automatically adjust the operating status of the uninterruptible power supply system to reduce the production of hydrogen. Lack of automatic control system: There are few control mechanisms in existing systems that can automatically adjust the output power of the uninterruptible power supply according to changes in hydrogen concentration, which makes it difficult to quickly reduce the hydrogen concentration in an emergency. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the present disclosure is to provide an ambient hydrogen content adjustment system to solve the problems in the related art.

[0006] A first aspect of the present disclosure provides an ambient hydrogen content regulating system, which is applied to an uninterruptible power supply system; the ambient hydrogen content regulating system comprises:

[0007] At least one hydrogen detector, disposed at a position ventilated to the internal and / or external environment of the uninterruptible power supply system, to detect a signal value of hydrogen content in the gas in the internal and / or external environment of the uninterruptible power supply system;

[0008] The control unit is communicatively connected to the at least one hydrogen detector and the uninterruptible power supply system, respectively. In response to the detected hydrogen content signal value meeting the warning condition, a first control signal for triggering the uninterruptible power supply system to reduce the power output to reduce the hydrogen content signal value is generated and sent to the uninterruptible power supply system.

[0009] In an embodiment of the first aspect, the uninterruptible power supply system controls its charging rate according to the first control signal.

[0012] The exhaust unit is used to increase the exhaust flow rate of the uninterruptible power supply system in response to the second control signal.

[0013] In an embodiment of the first aspect, the environmental hydrogen content regulation system further includes: a detection device, communicatively connected to the at least one hydrogen detector, for detecting a working state of the at least one hydrogen detector to obtain working state information.

[0014] In an embodiment of the first aspect, the at least one hydrogen gas detector comprises:

[0015] a content collection module, used for converting the collected gas content into the hydrogen content signal value;

[0016] an output module, communicatively connected to the content acquisition module and the control unit, and configured to output the hydrogen content signal value to the control unit;

[0017] A power supply module is electrically connected to the content collection module and the output module for supplying power.

[0018] In an embodiment of the first aspect, the content collection module includes:

[0019] A collection sensor, used to collect the gas content and generate an analog signal;

[0020] An analog-to-digital converter is connected to the acquisition sensor and is used to convert the analog signal into a digital signal to form the hydrogen content signal value.

[0021] In an embodiment of the first aspect, the at least one hydrogen gas detector is an explosion-proof structure;

[0022] And / or, the material of the at least one hydrogen detector is anti-static material.

[0023] In an embodiment of the first aspect, the warning condition includes at least one of the following: the hydrogen content signal value reaches a preset warning value; the hydrogen content signal value reaches the warning value and continues for a preset time period and / or shows an upward trend.

[0024] In an embodiment of the first aspect, the ambient hydrogen content regulation system further includes: an alarm unit, which is communicatively connected to the control unit and performs an alarm action in response to an alarm signal generated by the control unit based on the detected hydrogen content signal value satisfying an alarm condition.

[0025] In an embodiment of the first aspect, the ambient hydrogen content adjustment system further includes: a human-machine interaction unit, communicatively connected to the control unit, and configured to display a corresponding hydrogen content value according to the hydrogen content signal value.

[0026] Beneficial effects of the present disclosure: By setting at least one hydrogen detector in the internal and / or external environment of the uninterruptible power supply system, real-time monitoring of the hydrogen content can be achieved. Once the hydrogen content reaches or exceeds the preset warning condition, the hydrogen detector will immediately send a signal to the control unit. The control unit will generate a first control signal and send it to the uninterruptible power supply system, thereby triggering the uninterruptible power supply system to automatically reduce the power output, effectively reducing the generation of hydrogen and avoiding potential safety risks. The present disclosure can effectively control the hydrogen concentration inside and around the uninterruptible power supply system, reducing the risk of fire or explosion caused by hydrogen accumulation.

[0038] In order to clearly describe the present disclosure, components not related to the description are omitted, and the same reference numerals are given to the same or similar components throughout the specification.

[0039] Throughout the specification, when a device is said to be "connected" to another device, this includes not only the case of "direct connection" but also the case of "indirect connection" by placing other elements therebetween. In addition, when a device is said to "include" a certain component, unless otherwise stated, it does not exclude other components, but means that other components may be included.

[0040] Although the terms first, second, etc. are used to represent various elements in this article in some examples, these elements should not be limited by these terms.

Terms defined in commonly used dictionaries are additionally interpreted as having meanings consistent with relevant technical literature and the message of the present disclosure, and shall not be overly interpreted as ideal or very formal meanings unless defined.

[0043] In the related art, the battery pack in the uninterruptible power supply system, especially the system using lead-acid batteries or hydrogen fuel cells, may produce hydrogen during the charging and discharging process. Hydrogen is a flammable and explosive gas, and there is a safety hazard when its concentration reaches a certain threshold. At present, the monitoring of hydrogen content inside the uninterruptible power supply system and the surrounding environment is mainly achieved through manual regular inspection or installation of simple hydrogen detection devices. However, the detection and treatment of hydrogen in the related art is inefficient and may be missed.

[0044] Therefore, in a first aspect of the present disclosure, there is provided an ambient hydrogen content regulating system, wherein the system is applied to an uninterruptible power supply system; Figure 1 As shown in the example, the ambient hydrogen content adjustment system includes:

[0045] At least one hydrogen gas detector 100, disposed at a position ventilated to the internal and / or external environment 300 of the uninterruptible power supply system 200, to detect a signal value of a hydrogen gas content in the gas in the internal and / or external environment 300 of the uninterruptible power supply system 200;

[0046] The control unit 400 is communicatively connected to the at least one hydrogen detector 100 and the uninterruptible power supply system 200, respectively. In response to the detected hydrogen content signal value meeting the warning condition, a first control signal for triggering the uninterruptible power supply system 200 to reduce the power output to reduce the hydrogen content signal value is generated and sent to the uninterruptible power supply system 200.

[0047] Specifically, in the embodiment of the first aspect, at least one hydrogen detection device is provided, and the hydrogen detection device can be placed in the internal environment of the uninterruptible power supply system 200, or can be placed in the position where the uninterruptible power supply system 200 exchanges air with the external environment 300, so as to measure the hydrogen content inside or around the uninterruptible power supply system 200. In some embodiments, it is better to place the hydrogen detector 100 in the uninterruptible power supply system 200, but in order to ensure that the hydrogen detector 100 will not explode or burn when the hydrogen content exceeds the standard. Therefore, in some embodiments, the at least one hydrogen detector 100 is an explosion-proof structure, which will not become an ignition source in a potentially explosive environment, and in some embodiments, the material of the at least one hydrogen detector 100 is an anti-static material to prevent the danger caused by static electricity accumulation. In some embodiments, multiple hydrogen detectors 100 can also be provided, which are placed in the internal environment of the uninterruptible power supply system 200 or in the ventilation position of the external environment 300 to improve the detection accuracy.

[0048] The control unit 400 determines the hydrogen content signal value detected by at least one hydrogen detector 100 to control the charging rate of the uninterruptible power supply system 200, and solves the problem of excessive hydrogen content from the source. Establish communication connections with at least one hydrogen detector 100 and the uninterruptible power supply system 200 respectively. When the received hydrogen content signal value meets the preset warning condition, the control unit 400 generates and sends a first control signal to the uninterruptible power supply system 200. In some embodiments, the warning condition includes at least one of the following: the hydrogen content signal value reaches the preset warning value; the hydrogen content signal value continues for a preset time after reaching the warning value and / or shows an upward trend. Specifically, an alarm is triggered when the hydrogen content exceeds a preset safety threshold. This threshold is usually determined based on the safety standard of hydrogen, such as a percentage of the lower explosion limit (LEL). In some embodiments, even if the hydrogen content reaches the warning value, if it is only a momentary situation, it may not be necessary to take immediate action. Therefore, the system may set a time threshold, and the alarm will only be triggered when the hydrogen content exceeds the warning value for a period of time. Or even if the hydrogen content has not yet reached the warning value, if its concentration is increasing rapidly, this itself may also pose a potential danger. In this case, the system can determine whether an alarm should be issued in advance by monitoring the rate of change of the hydrogen content.

[0049] The first control signal is used to instruct the uninterruptible power supply system 200 to reduce the power output. After receiving the first control signal, the uninterruptible power supply system 200 automatically reduces the power output according to the instruction. For example, in some embodiments, the uninterruptible power supply system 200 controls its charging rate according to the first control signal, thereby reducing the charging current or entering a low power consumption mode, extending the charging cycle, and thus reducing the generation of hydrogen. As the uninterruptible power supply system 200 adjusts its working state, the hydrogen content gradually decreases until it returns to a safe level. When the hydrogen content drops to a safe range, the control unit 400 will stop sending the first control signal, and the uninterruptible power supply system 200 can resume normal operation mode as needed.

[0050] In some embodiments, the hydrogen content in the uninterruptible power supply system 200 can be reduced by extracting the hydrogen in the uninterruptible power supply system 200, such as Figure 2 As shown in the embodiment, the environmental hydrogen content regulating system further includes: an exhaust unit, which is arranged at a position ventilated with the inside of the uninterruptible power supply system 200 and / or the external environment 300 and is communicatively connected to the control unit 400;

[0051] The control unit 400 is further configured to generate a second control signal and send it to the exhaust unit in response to the detected hydrogen content signal value meeting the warning condition;

[0052] The exhaust unit is used to increase the exhaust flow rate of the uninterruptible power supply system 200 in response to the second control signal.

[0053] Specifically, in some embodiments, the exhaust unit can be placed inside the uninterruptible power supply system 200 to extract the gas in the system and then extract the hydrogen, or the exhaust unit can be placed at a location where the external environment 300 of the uninterruptible power supply system 200 is ventilated. When the control unit 400 detects that the hydrogen content meets the warning condition, it sends a second control signal to the exhaust unit.

[0054] The exhaust unit can be composed of one or more fans. Under normal conditions, the exhaust unit extracts gas from the system at a normal rate. When receiving a second control signal, the exhaust flow rate is increased to quickly reduce the hydrogen concentration in the uninterruptible power supply system 200 until it drops to a safe level.

[0055] In some embodiments, in order to detect the status of at least one hydrogen gas detector 100 and whether it is intact, Figure 3 As described in the embodiment, a detection device is further provided, which is communicatively connected to the at least one hydrogen detector 100 and is used to detect the working state of the at least one hydrogen detector 100 to obtain working state information.

[0056] Specifically, the hydrogen detector 100 and the detection device can be equipped with wireless communication modules, such as Wi-Fi, Bluetooth, Zigbee or other low-power wireless communication technologies, so as to achieve wireless connection between the hydrogen detector 100 and the detection device, or through a wired connection. The specific connection method is selected according to the actual use scenario and requirements. In some embodiments, the detection device can be placed in the internal environment of the uninterruptible power supply system 200, or it can be placed outside the uninterruptible power supply system 200.

[0057] In some embodiments, the detection device sends a status request command to the hydrogen detector 100 at a predetermined time interval (periodic detection) or when the hydrogen content exceeds a preset threshold (event trigger detection). This process can be done by directly sending instructions through a wired connection, or by sending through a wireless communication module. After receiving the status request, the hydrogen detector 100 sends the current working status information (such as sensor response time, signal strength, sensitivity, etc.) and packages this information into a data packet through a corresponding communication method (wired or wireless) and sends it back to the detection device. The detection device receives the data packet, parses the working status information therein, and checks whether each parameter meets the preset standard. If all state parameters are within the preset range, the hydrogen detector 100 is considered to be working normally; if any parameter exceeds the preset range, the hydrogen detector 100 is considered to be abnormal, and an alarm message is generated, which may also trigger further fault diagnosis or maintenance instructions. In some embodiments, the detection device is also connected to the control unit 400, which is used to send the results of each detection to the control unit 400, thereby generating a detailed report, including historical records, alarm information, etc., for subsequent analysis and maintenance.

[0058] Optional, in Figure 4 In an embodiment, the at least one hydrogen gas detector 100 comprises:

[0059] a content collection module 110, configured to convert the collected gas content into the hydrogen content signal value;

[0060] an output module 120, communicatively connected to the content acquisition module 110 and the control unit 400, and configured to output the hydrogen content signal value to the control unit 400;

[0061] A power module 130 is electrically connected to the content collection module 110 and the output module 120 for power supply.

[0062] Specifically, in some embodiments, the content acquisition module 110 includes one or more sensors for detecting the concentration of hydrogen in the environment. The sensor may be an electrochemical sensor, a semiconductor sensor, or other types of sensors. When hydrogen contacts the sensor, the sensor generates an electrical signal, which is proportional to the concentration of hydrogen. The content acquisition module 110 is responsible for converting the detected hydrogen concentration into an electrical signal and processing the signal into a readable numerical value, i.e., a hydrogen content signal value. The output module 120 sends the hydrogen content signal value generated by the content acquisition module 110 to the control unit 400 via a wired or wireless method. The output module 120 establishes a communication connection with the content acquisition module 110 and also establishes a communication connection with the control unit 400. It can use various communication protocols, such as analog signals, digital signals, RS-485, CAN bus, Bluetooth, Wi-Fi, etc., so as to transmit the hydrogen content signal value to the control unit 400. The power module 130 provides power for the entire hydrogen detector 100. The power module 130 generally includes a battery or an external power adapter to ensure that the content collection module 110 and the output module 120 have sufficient power to operate. In some cases, the power module 130 can also be a solar panel or other forms of renewable energy system to adapt to different application environments.

[0063] Optional, in Figure 5 In an embodiment, the content collection module 110 includes:

[0064] A collection sensor 111, used to collect the gas content and generate an analog signal;

[0065] An analog-to-digital converter 112 is connected to the acquisition sensor 111 and is used to convert the analog signal into a digital signal to form the hydrogen content signal value.

[0066] Specifically, in some embodiments, the acquisition sensor 111 is in contact with the gas to be measured, can respond to hydrogen and generate an analog electrical signal (usually current or voltage) proportional to the concentration of hydrogen. In some embodiments, an amplifier is also provided to amplify the analog signal for subsequent processing. Because modern electronic devices, especially controllers and computers, can usually only process digital signals. Therefore, an analog-to-digital converter 112 is also provided, and the analog-to-digital converter 112 samples the analog signal at a certain sampling frequency and quantizes it into a series of discrete digital values. The processed digital signal can be read by the control system or microprocessor, and the actual concentration of hydrogen can be further calculated. The analog-to-digital conversion process belongs to the relevant technology in this field.

[0067] Optional, in Figure 6In an embodiment, the environmental hydrogen content regulating system further includes: an alarm unit 700, which is communicatively connected to the control unit 400 and performs an alarm action in response to an alarm signal generated by the control unit 400 based on the detected hydrogen content signal value satisfying an alarm condition.

[0068] Specifically, in some embodiments, the alarm unit 700 is connected to the control unit 400 through communication, and once an alarm signal sent by the control unit 400 is received, a corresponding alarm action is performed, such as sounding an alarm, flashing light, etc.

[0069] Optional, in Figure 7 In an embodiment, the environmental hydrogen content regulating system further includes: a human-computer interaction unit 800, which is communicatively connected to the control unit 400 and is used to display a corresponding hydrogen content value according to the hydrogen content signal value.

[0070] Specifically, in some embodiments, the human-computer interaction unit 800 is used to display the corresponding hydrogen content value according to the hydrogen content signal value, so that the operator can intuitively understand the hydrogen concentration in the current environment.

[0071] The above embodiments are merely illustrative of the principles and effects of the present disclosure, and are not intended to limit the present disclosure. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present disclosure. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed in the present disclosure shall still be covered by the protection scope of the present disclosure.
