Description

[0001] The present disclosure relates to the technical field of ship power supply, and in particular to a hydrogen concentration control device in an uninterruptible power supply environment. Background Art

[0002] With the widespread application of uninterruptible power supply (UPS) systems in various fields, it has become particularly important to ensure the safe operation of uninterruptible power supply systems. Uninterruptible power supply systems are usually equipped with battery packs to provide backup power when the power grid is interrupted. However, during the charging and discharging process of the battery pack, hydrogen may be generated. Hydrogen is a colorless, odorless, and highly flammable gas. When its concentration reaches a certain threshold, there are serious safety hazards. In the uninterruptible power supply system in the related art, a simple hydrogen detection device is usually used to monitor the hydrogen concentration in the battery room. These detection devices are usually able to detect the presence of hydrogen and issue an alarm when the hydrogen concentration exceeds a preset threshold. However, there are some limitations in the methods in these related technologies: when the hydrogen concentration exceeds the safety threshold, manual intervention is usually required to manually turn on the ventilation equipment or take other measures to reduce the hydrogen concentration, which may lead to untimely response. The hydrogen detection device in the related art often does not have an automatic control function and cannot automatically adjust the operating state of the uninterruptible power supply system or take measures to reduce the hydrogen concentration according to the change of hydrogen concentration.

[0034] In the related art, when the hydrogen concentration exceeds the safety threshold, manual intervention is usually required to manually open the ventilation equipment or take other measures to reduce the hydrogen concentration, which may lead to delayed response. The hydrogen detection device 100 in the related art often does not have an automatic control function and cannot automatically adjust the operating state of the uninterruptible power supply system according to the change of hydrogen concentration or take measures to reduce the hydrogen concentration.

[0035] In the present disclosure, the hydrogen detection device can monitor the hydrogen concentration inside the uninterruptible power supply system and the surrounding environment in real time, and send the data to the main control module. Once the hydrogen concentration exceeds the safety standard, the main control module can automatically control the exhaust module to increase the exhaust volume, reduce the hydrogen concentration in time, ensure environmental safety, and reduce the risk of delays caused by human factors.

[0036] A first aspect of the present disclosure provides a hydrogen concentration control device in an uninterruptible power supply environment, comprising:

[0037] At least one hydrogen detection device 100 is disposed at a position ventilated to the internal and / or external environment 300 of the uninterruptible power supply system 200 to detect a hydrogen concentration signal value of the gas in the internal and / or external environment 300 of the uninterruptible power supply system 200;

[0038] An exhaust module 400 is disposed at a position ventilated with the internal and / or external environment 300 of the uninterruptible power supply system 200 and is used to exhaust the gas of the uninterruptible power supply system 200.

[0039] The main control module 500 is communicatively connected to the at least one hydrogen detection device 100 and the exhaust module 400, and is used to control the exhaust module 400 to increase the internal exhaust volume of the uninterruptible power supply system 200 to reduce the hydrogen concentration signal value in response to the hydrogen concentration signal value exceeding the safety standard.

[0040] Specifically, in some embodiments, at least one hydrogen detection device 100 is provided, and the hydrogen detection device 100 can be placed in the internal environment of the uninterruptible power supply system 200, or can be placed at a location where the uninterruptible power supply system 200 exchanges gas with the external environment 300, so as to measure the hydrogen content inside the uninterruptible power supply system 200 or around the uninterruptible power supply system 200. Figure 3In the example, the uninterruptible power supply system 200 includes an electrical cabinet 210, and the at least one hydrogen detection device 100 is arranged in the electrical cabinet 210. However, in order to ensure that the hydrogen detector will not explode or burn when the hydrogen content exceeds the standard. Therefore, in some embodiments, the at least one hydrogen detection device is an explosion-proof structure and will not become an ignition source in a potentially explosive environment. In some embodiments, the material of the at least one hydrogen detection device is an anti-static material to prevent the danger caused by static electricity accumulation. In some embodiments, multiple hydrogen detectors can be set, respectively placed in the internal environment of the uninterruptible power supply system 200 or in a ventilated position of the external environment 300 to improve the detection accuracy.

[0041] The uninterruptible power supply system 200 discharges the internal gas through the exhaust module 400. The exhaust module 400 can be placed in the uninterruptible power supply system 200 or in a position where the uninterruptible power supply system 200 is ventilated with the external environment 300 to extract the gas inside the uninterruptible power supply system 200, thereby discharging the hydrogen. In some embodiments, the exhaust module 400 can be a fan, connected to the air duct on the uninterruptible power supply system 200 that is connected to the external environment 300 to extract air. The main control module 500 makes a judgment based on the hydrogen concentration signal value detected by the hydrogen detection device 100. When the detected hydrogen concentration signal value exceeds the safety standard, the main control module 500 will make a judgment based on the preset logic to determine whether the exhaust volume needs to be increased. If the exhaust volume needs to be increased, the main control module 500 will generate a corresponding control instruction to control the exhaust module 400 to increase the exhaust volume to reduce the hydrogen concentration. When the hydrogen concentration drops below the safety standard, the main control module 500 will generate a control instruction again to tell the exhaust module 400 to restore the normal exhaust volume. The main control module 500 and the exhaust module 400 are connected via a communication interface, which can be wired or wireless.

[0042] In some embodiments, the safety standard can be a fixed threshold or a dynamically adjusted one. The safety standard includes at least one of the following: the hydrogen concentration signal value reaches a preset warning value; the hydrogen concentration 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 standard, such as a certain 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, immediate action may not be required. 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 constitute 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.

[0043] In some embodiments, the amount of hydrogen generated can be controlled by controlling the power output of the uninterruptible power supply system 200, so as to reduce the concentration of hydrogen in the uninterruptible power supply system 200. The charging power of the battery can be reduced by reducing the power output voltage or current.

[0044] Optional, in Figure 2 In the example, the at least one hydrogen detection device 100 includes:

[0045] a collection sensor 110, disposed at a position ventilated to the internal and / or external environment 300 of the uninterruptible power supply system 200, for collecting an analog signal of hydrogen concentration;

[0046] A converter 120 is communicatively connected to the acquisition sensor 110 and is used to convert the analog signal collected by the acquisition sensor 110 into a digital signal for reading, so as to generate the hydrogen concentration signal value.

[0047] Specifically, in some embodiments, the acquisition sensor 110 is used to measure the concentration of hydrogen in the air and is installed in a position ventilated to the inside of the uninterruptible power supply system 200 (UPS) and / or the external environment 300 so as to accurately detect the presence and concentration of hydrogen in the environment. Common types of hydrogen sensors include but are not limited to catalytic combustion sensors, electrochemical sensors, semiconductor sensors, etc. When hydrogen exists around the sensor, the sensor will respond to it. The sensor will output an analog signal proportional to the detected hydrogen concentration, such as a voltage or current change. The function of the converter 120 is to convert the analog signal output by the acquisition sensor 110 into a digital signal. The process of digital-to-analog conversion is a related technology in the field and will not be described in detail here.

[0048] Optionally, the uninterruptible power supply system 200 is connected to at least one of the at least one hydrogen detection device 100, the main control module 500 and the exhaust module 400 to provide power for the connected devices and / or modules.

[0049] Specifically, in some embodiments, the UPS is responsible for not only supplying power to the critical load, but also supplying power to any one or more of the hydrogen detection device 100, the main control module 500, and the exhaust module 400, thereby reducing energy waste. In another embodiment, at least one of the hydrogen detection device 100, the main control module 500, and the exhaust module 400 can also be powered by an external power supply.

[0050] Optional, in Figure 4In the example, the hydrogen concentration control device further includes: a warning module 600, which is communicatively connected to the main control module 500 and performs a warning action in response to a warning signal generated by the main control module 500 based on the detected hydrogen concentration signal value exceeding the safety standard.

[0051] Specifically, in some embodiments, when the main control module 500 detects that the hydrogen concentration signal value exceeds the safety standard, a warning signal is generated, and the warning module 600 performs a corresponding warning action after receiving the signal. In some embodiments, in order to better cope with the safety requirements in different situations, the main control module 500 pre-sets a multi-level alarm threshold, and the main control module 500 outputs a warning signal of a corresponding alarm level according to the hydrogen concentration signal value and the multi-level alarm threshold. Whenever the hydrogen concentration reaches one of the thresholds, the main control module 500 outputs a warning signal of a corresponding alarm level. For example, three alarm levels can be set: low-level alarm, intermediate alarm, and high-level alarm. Low-level alarm: When the hydrogen concentration slightly exceeds the normal range, the system may trigger a sound alarm or a visual prompt to alert the staff. Intermediate alarm: If the hydrogen concentration increases further, in addition to the sound and visual prompts, the system may also start a more obvious alarm, such as a louder siren, and send an alarm message to relevant personnel through the network. Advanced alarm: When the hydrogen concentration reaches a very dangerous level, in addition to all the above actions, the system may also initiate emergency evacuation procedures or automatically shut down the hydrogen supply source (i.e. the uninterruptible power supply module is not charging) to ensure the safety of personnel.

[0052] Optional, in Figure 5 In the example, the hydrogen concentration control device further includes: a human-computer interaction module 700, which is communicatively connected to the main control module 500 and is used to display the corresponding hydrogen concentration value according to the hydrogen concentration signal value.

[0053] Specifically, in some embodiments, the human-computer interaction module 700 displays the corresponding hydrogen concentration value in real time on the display screen according to the hydrogen concentration signal value received from the main control module 500. In addition to the display function, the human-computer interaction module 700 can also serve as an interface for operators to interact with the system, allowing them to make necessary settings and adjustments, such as setting alarm thresholds, viewing system status, etc.

[0054] 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.
