In one embodiment, the monitoring module includes: and the monitoring probe group is used for monitoring the state of each monitoring point of the power supply device.

Specifically, the monitoring module may be configured to mount at least one monitoring probe set on each water hydrogen machine, and the three water hydrogen machines are mounted with at least three monitoring probe sets for monitoring the operating states of the respective water hydrogen machines. For each water hydrogen machine, a pressure detection probe can be used for detecting the pressure of hydrogen gas in a hydrogen gas supply pipeline, and an airtight probe can be used for monitoring the airtightness of the pipeline.

At least one sound probe, at least one temperature probe and at least one humidity probe are installed in the carriage, and the whole noise, the temperature and the humidity and the like in the carriage can be monitored.
Therefore, the potential danger of the power supply device can be predicted by monitoring various indexes of the power supply device such as pressure, vibration, temperature, humidity, static electricity, sound and the like in real time through the monitoring probe group, so that the power supply process is safer and more reliable.
In one embodiment, the analysis module is configured to analyze the safety of the entire interior of the power supply device and the mobile power supply vehicle compartment according to a comparison between the monitored state of the interior of the power supply device and the mobile power supply vehicle compartment and a predetermined threshold. The analysis module acquires various index data which are monitored by the monitoring probe group and represent the state of the power supply device in real time, compares the monitored index data with a preset threshold value, and performs safety analysis on each water hydrogen machine, the whole power supply device and the whole interior of the power supply vehicle carriage to obtain an evaluation value of a safety grade, wherein the safety grade is divided into three grades of safety, risk and abnormity.
Wherein, each item of index data comprises: various index data of a single water hydrogen machine and various index data of the whole interior of the carriage of the power supply train. The types of index data of the single water hydrogen machine comprise: pressure, airtightness, vibration frequency, vibration amplitude, electrostatic accumulation voltage, and temperature; the index data types of the entire power supply train compartment include: vibration frequency, vibration amplitude, temperature, humidity, sound decibel. The predetermined threshold values include a first threshold value and a second threshold value for each of the above types of index data, for example, for a single water hydrogen machine, the first threshold values include a first pressure threshold value, a first airtightness threshold value, a first vibration frequency threshold value, a first vibration amplitude threshold value, a first static electricity accumulation threshold value, a first temperature threshold value; the second threshold includes a second pressure threshold, a second airtightness threshold, a second vibration frequency threshold, a second vibration amplitude threshold, a second static electricity accumulation threshold, and a second temperature threshold.

The analysis module carries out safety evaluation based on the index data and the preset threshold value, and analyzes the safety level of the current power supply device, wherein the safety level comprises the following steps: three levels of security, risk and exception. The safety evaluation can be divided into the safety evaluation of a single water hydrogen machine, the overall safety evaluation of a power supply device and the overall safety evaluation of a mobile power supply vehicle. The safety evaluation of the single water hydrogen machine comprises temperature safety evaluation, pressure safety evaluation, airtight safety evaluation, vibration safety evaluation, temperature safety evaluation and static safety evaluation aiming at each water hydrogen machine. And according to the index data conditions of all the water-hydrogen machines, the analysis module evaluates the overall safety of the power supply device to obtain the overall safety level of the power supply device. The safety evaluation of the whole power supply vehicle carriage comprises carriage vibration safety evaluation, carriage noise safety evaluation, carriage whole temperature safety evaluation and carriage whole humidity safety evaluation.
In one embodiment, for the safety evaluation of a single water hydrogen machine, for any type of data index reflecting the working state of the water hydrogen machine, when the data index is within a range not higher than a first threshold corresponding to the type, the safety represented by the type of data index of the water hydrogen machine is judged to be in a safe state. Specifically, for example, when the pressure value of a single water hydrogen machine is within the first pressure threshold, the water hydrogen machine is normally operated, and the safety level of the pressure safety evaluation is safety. And when any type of data index is larger than the first threshold value but not higher than the second threshold value, judging that the safety represented by the type of data index of the water hydrogen machine is in a risk state. For example, when the pressure value of the single water hydrogen machine is greater than the first pressure threshold value but not greater than the second pressure threshold value, the safety level of the pressure safety evaluation of the water hydrogen machine is a risk. And when any type of data index is larger than a second threshold value, judging that the safety represented by the type of data index of the water hydrogen machine is in an abnormal state. For example, when the pressure value of the single water hydrogen machine is greater than the second pressure threshold value, the safety level of the pressure safety evaluation of the water hydrogen machine is abnormal.
The safety level of the whole power supply device is converted into a safety integral value for each type of the water hydrogen machine which is in parallel operation in the power supply device, and the safety integral value of the whole power supply device is obtained through integral accumulation. A first integral threshold value and a second integral threshold value are also set for a safety integral value of the entire power feeding device, and when the safety integral value is within a range not higher than the first integral threshold value, it is determined that the safety of the entire power feeding device is in a safe state. And when the safety integral value is larger than the first integral threshold value but not higher than the second integral threshold value, the safety of the whole power supply device is judged to be in a risk state. When the safety integral value of the entire power supply device is larger than the second integral threshold value, it is determined that the safety of the entire power supply device is in an abnormal state. Specifically, for example, for each of the safety levels of the water hydrogen machine in the types of pressure, airtightness, vibration frequency, vibration amplitude, electrostatic accumulation voltage, and temperature, when any one of the safety levels is safe, the converted safety integral value is 0, when the safety level is a risk, the converted safety integral value is 50, and when the safety level is an abnormality, the converted safety integral value is 100. The safety levels of the pressure safety evaluation of the three water-hydrogen machines which work in parallel in the power supply device are all safe; two of the air tightness safety levels are safe, and one is a risk; the vibration frequency safety level is safe for two, and risk for one; the safety levels of the vibration amplitude are all safe; the safety level of the static accumulated voltage is two risks, and one is safety; the three temperature safety levels are all risks; the safety integral value of the power supply apparatus as a whole is 350. Assuming that the first integral threshold value is 300 and the second integral threshold value is 450, the overall safety level of the power supply device is at risk. Of course, according to actual needs, there may be a part of the parallel water hydrogen machines equipped with the power supply device that are not actually started to operate, and therefore, the first integration threshold value and the second integration threshold value may be adjusted according to the number of the water hydrogen machines that are actually operated in parallel; for example, if only two of three water hydrogen machines with parallel power supply devices are in actual operation, the first integration threshold value may be proportionally adjusted to 200, and the second integration threshold value may be proportionally adjusted to 300. As another embodiment, for each type of safety level, the same safety level of each type may be converted into a different safety integral value depending on the importance of the type on safety, for example, for each type of safety level of the water-hydrogen machine, such as pressure, airtightness, vibration frequency, vibration amplitude, static electricity accumulation voltage, and temperature, when any type of safety level is safe, the converted safety integral value is 0; when the safety levels of pressure, air tightness and temperature are risks, the converted safety integral value is 50; when the vibration frequency, the vibration amplitude and the safety level of the static electricity accumulated voltage are risks, the converted safety integral value is 40; when either type of security level is abnormal, the converted security score value is 100.
For the safety evaluation of the whole power supply vehicle carriage, for any type of data index reflecting the working state of the whole carriage, when the data index is in a range not higher than a first threshold value corresponding to the type, the safety of the whole carriage represented by the type of data index is judged to be in a safe state. For example, when the amplitude of the vibration of the whole vehicle compartment is within a range not higher than the threshold value of the amplitude of the vibration of the first vehicle compartment, the safety level of the evaluation of the safety of the vibration of the whole vehicle compartment is safe. When the data index is in a range higher than a first threshold value corresponding to the type and not higher than a second threshold value corresponding to the type, it is determined that the safety of the vehicle compartment as a whole represented by the data index of the type is in a risk state. For example, when the overall car vibration amplitude is within a range that is higher than the first car vibration amplitude threshold value and not higher than the second car vibration amplitude threshold value, then the safety level of the overall car vibration safety assessment is a risk. When the data index is in a range higher than a second threshold value corresponding to the type, it is determined that the safety of the entire car indicated by the data index of the type is in an abnormal state. For example, when the amplitude of the vibration of the whole vehicle cabin is within a range higher than the threshold value of the amplitude of the vibration of the second vehicle cabin, the safety level of the evaluation of the safety of the vibration of the whole vehicle cabin is abnormal.
In one embodiment, the control module is configured to issue a control command to the power supply device to adjust the power supply device to a safe state according to the safety level of each of the water hydrogen machine, the power supply device as a whole and the power supply vehicle compartment as a whole when the safety level is in a risk state and/or the abnormal state, so as to improve the working state of each of the water hydrogen machine, the power supply device as a whole and the power supply vehicle compartment as a whole and prevent potential danger. When the safety level obtained by any type of safety evaluation of a certain water hydrogen machine is abnormal, the controller controls the water hydrogen machine to stop working, and other water hydrogen machines continue working without being influenced by the safety level; and when the safety level obtained by the safety evaluation of the whole power supply device or the whole interior of the mobile power supply vehicle compartment is abnormal, the controller controls all the water-hydrogen machines to stop working. And when the safety levels of a part of water-hydrogen machines in the power supply device are at risk, the safety levels of the rest of water-hydrogen machines are normal, and the safety levels of the whole power supply device and the whole interior of the power supply vehicle carriage are also normal, the working power of the water-hydrogen machines with the risk safety levels can be reduced, and the working power of the water-hydrogen machines with the normal safety levels can be increased. When the safety level of a part of water-hydrogen machines in the power supply device is at risk, the safety level of the rest of water-hydrogen machines is normal, and the safety level of the whole power supply device or the whole inside of a power supply vehicle carriage is also at risk, the working power of the water-hydrogen machines with the safety level at risk is reduced, and the working power of the water-hydrogen machines with the other safety levels at normal is kept unchanged. When the safety level of all the water hydrogen machines of the power supply device is normal, but the safety level of the whole interior of the carriage of the power supply vehicle is a risk, the working power of any one water hydrogen machine is reduced. Therefore, when the safety state of any water-hydrogen machine is abnormal, and the safety state of the whole power supply device with a plurality of parallel water-hydrogen machines or the whole safety state in the carriage is abnormal, the control module controls the abnormal water-hydrogen machines or the whole water-hydrogen machines to be in a shutdown state in time so as to avoid unexpected risks; when the safety state of one or a part of the water-hydrogen machines is a risk, but the safety states of the whole power supply device and the whole carriage are kept normal, the water-hydrogen machines in the risk state are not enough to bring obvious influence on the safety state of the whole mobile power supply vehicle, under the condition, the safety risk can be controlled and reduced in a mode of reducing the working power of the water-hydrogen machines in the risk state, and meanwhile, the working power of the water-hydrogen machines in other normal states can be properly increased in order to ensure the power transmission capability of the whole mobile power supply vehicle; when one or a part of the water hydrogen machines are in a risk state, and the safety state of the whole power supply device or the whole carriage is also in a risk state, the risk state of the water hydrogen machine has brought certain influence on the safety state of the whole mobile power supply vehicle, and the safety of the mobile power supply vehicle is in a certain risk state as a whole; when the safety levels of all the water hydrogen machines are normal, but the safety level of the whole inside of the carriage of the power supply vehicle is a risk, the risk may be caused by an accumulation effect of parallel operation of the water hydrogen machines of the power supply vehicle, for example, the accumulation of vibration of the water hydrogen machines causes the amplitude of the whole vibration to exceed a limit, and at this time, the operating power of one of the water hydrogen machines can be reduced selectively, so as to eliminate a part of the safety risk on the whole.
The monitoring module keeps real-time monitoring and output of index data of each water hydrogen machine and each safety state of the whole inside of the power supply vehicle carriage, the analysis module keeps analysis of the safety level of each water hydrogen machine, the whole power supply device and the whole inside of the power supply vehicle carriage in real time according to the index data, and the control module keeps dynamic adjustment of the working state of the water hydrogen machines according to the change of the safety level of each water hydrogen machine, the whole power supply device and the whole inside of the power supply vehicle carriage and the control mode; for example, when the safety levels of a part of water-hydrogen machines in the power supply device are at risk, the safety levels of the rest of water-hydrogen machines are normal, and the safety level of the whole power supply device or the whole interior of the power supply vehicle carriage is also at risk, the working power of the water-hydrogen machine with the safety level at risk is reduced, and the working power of the water-hydrogen machines with the other safety levels at normal is kept unchanged; after a period of time, when the safety level of the whole power supply device or the whole interior of the power supply vehicle carriage is recovered to be normal from the risk, the working power of the water hydrogen machine in other normal states can be increased according to the control mode. The control power is gradually adjusted to increase and decrease the working power of the water-hydrogen machine, for example, the control power can be increased or decreased by 10% each time, and then the working power of the water-hydrogen machine is increased or decreased according to the change state of the safety level.
Therefore, the invention realizes the temporary power supply to the electric facilities such as the 5G base station and the like under the condition of power failure through the safe power supply system of the water-hydrogen generator comprising the power supply device and the safety control and the mobile power supply vehicle carrying the system; and an effective safe power supply mechanism is established, each water-hydrogen generator and the whole working state thereof can be accurately monitored, the safety level is evaluated, and a proper control strategy is adopted, particularly, the water-hydrogen generator can be prevented from further deteriorating to a safe abnormal state through intervention under the risk level, safety evaluation and control are carried out on each water-hydrogen generator per se, and effective safety evaluation and control are also carried out on the whole risk accumulated when the water-hydrogen generators work in a carriage in parallel, so that convenience of mobile power supply is realized, and the power supply process is safer and more reliable.
The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
