In this embodiment, the electrolysis feedback amount is used as the difference between the current oxyhydrogen electrolysis current and the standard electrolysis current of the oxyhydrogen preparation device, i.e. the electrolysis feedback amount is used as the judgment basis for the current oxyhydrogen preparation rate of the oxyhydrogen preparation device. The preset feedback quantity is used as the standard electrolysis feedback quantity of the oxyhydrogen preparation device, namely the preset feedback quantity is used as the comparison standard of the electrolysis feedback quantity, and the preset feedback quantity is used for comparing with the electrolysis feedback quantity, so that the matching degree between the electrolysis feedback quantity and the preset feedback quantity is convenient to determine, and the current oxyhydrogen preparation rate condition of the oxyhydrogen preparation device is convenient to determine. The electrolysis feedback quantity is matched with the preset feedback quantity, which indicates that the current oxyhydrogen preparation rate of the oxyhydrogen preparation device is equivalent to a standard rate, namely indicates that the current oxyhydrogen preparation rate of the oxyhydrogen preparation device reaches a standard, namely indicates that the current oxyhydrogen preparation rate of the oxyhydrogen preparation device meets requirements, so that a gas preparation rate stabilizing signal is sent to the gas preparation power supply device, so that a signal for maintaining stable gas preparation is conveniently sent to the gas preparation power supply device, the power supply signal output by the gas preparation power supply device to the oxyhydrogen preparation device is conveniently controlled to be a stable value, the gas preparation rate of the oxyhydrogen preparation device is conveniently controlled to be the same as the previous rate, and the current oxyhydrogen preparation rate of the oxyhydrogen preparation device is maintained.
Further, the detecting whether the electrolysis feedback quantity is matched with a preset feedback quantity also comprises the following steps; and when the electrolysis feedback quantity is not matched with the preset feedback quantity, adjusting a gas-making modulation signal sent to the gas-making power supply device. In this embodiment, the mismatch between the electrolysis feedback and the preset feedback indicates that the current hydrogen and oxygen production rate of the hydrogen and oxygen production device is different from the standard rate, i.e., indicates that the current hydrogen and oxygen production rate of the hydrogen and oxygen production device does not meet the standard, i.e., indicates that the current hydrogen and oxygen production rate of the hydrogen and oxygen production device does not meet the requirements. Thus, the gas preparation rate modulation signal is conveniently sent to the gas preparation power supply device by sending the gas preparation modulation signal to the gas preparation power supply device, so that the power supply signal output by the gas preparation power supply device to the oxyhydrogen preparation device is conveniently adjusted, the gas preparation rate of the oxyhydrogen preparation device is conveniently adjusted to the required gas preparation rate, and the current oxyhydrogen preparation rate of the oxyhydrogen preparation device is effectively adjusted to the final required gas preparation rate.

In this embodiment, the electrolysis feedback amount being greater than the predetermined feedback amount indicates that the current hydrogen and oxygen production rate of the hydrogen and oxygen production apparatus is greater than the standard rate, i.e., indicates that the current hydrogen and oxygen production rate of the hydrogen and oxygen production apparatus is greater than the standard, i.e., indicates that the current hydrogen and oxygen production rate of the hydrogen and oxygen production apparatus does not meet the requirements. Thus, at this time, the gas making depressurization signal is sent to the gas making power supply device, so that the electrolysis voltage output by the gas making power supply device to the oxyhydrogen preparation device is convenient to reduce, the signal for reducing the gas preparation rate is convenient to send to the gas making power supply device, the gas preparation rate of the oxyhydrogen preparation device is convenient to reduce to the required rate, and the current oxyhydrogen preparation rate of the oxyhydrogen preparation device is effectively adjusted to the final required gas making rate.
Still further, when the electrolysis feedback amount does not match the preset feedback amount, adjusting a modulated gas modulation signal sent to the modulated gas power supply device includes: and when the electrolysis feedback quantity is smaller than the preset feedback quantity, sending a gas making pressure rise signal to the gas making power supply device so as to increase the gas preparation quantity of the oxyhydrogen preparation device. In this embodiment, the electrolysis feedback amount being less than the predetermined feedback amount indicates that the current hydrogen and oxygen production rate of the hydrogen and oxygen production apparatus is less than the standard rate, i.e., indicates that the current hydrogen and oxygen production rate of the hydrogen and oxygen production apparatus is less than the standard, i.e., indicates that the current hydrogen and oxygen production rate of the hydrogen and oxygen production apparatus does not meet the requirements. Thus, at this time, the gas production boosting signal is sent to the gas production power supply device, so that the electrolysis voltage output by the gas production power supply device to the oxyhydrogen preparation device is conveniently increased, a signal for increasing the gas preparation rate is conveniently sent to the gas production power supply device, the gas preparation rate of the oxyhydrogen preparation device is further conveniently increased to a required rate, and the current oxyhydrogen preparation rate of the oxyhydrogen preparation device is effectively adjusted to the final required gas production rate.
As can be understood, after the oxyhydrogen preparation device is electrified, the positive electrode and the negative electrode in the electrolytic bin are electrified so as to carry out electrolysis operation on the electrolytic medium in the electrolytic bin, so that hydrogen and oxygen in corresponding volume ratio can be generated by electrolysis. Wherein, electrolysis storehouse and gas storage storehouse intercommunication, produced gas temporary storage in the electrolysis storehouse is in the gas storage storehouse to the user uses gas through the gas storage storehouse that corresponds, specifically, the gas storage storehouse has two, and one is used for storing hydrogen, and another is used for storing oxygen.
However, in actual use, the volume of the gas in the gas storage bin increases with time, the gas outlet of the gas storage bin is communicated with the suction nozzle, and when the gas storage rate in the gas storage bin is greater than or equal to the gas outlet rate, a large part of the gas prepared by the oxyhydrogen preparation device is wasted, for example, after the gas storage bin is opened by mistake, no one can use hydrogen or oxygen; as another example, during normal use, the rate at which a user inhales gas is slow. These conditions lead to unnecessary waste of gas and, in the worst case, to an overoxidation of the surrounding environment, i.e. to an intoxicated environment for the user.
In order to reduce the probability of excessive waste of gas, the method sends a gas regulating signal to a gas production and power supply device according to the electrolysis feedback quantity so as to regulate the gas production quantity of the oxyhydrogen production device, and then further comprises the following steps:
obtaining the separation pressure of a gas storage bin of the oxyhydrogen preparation device;
detecting whether the separation pressure is greater than or equal to a preset pressure;
and when the separation pressure is greater than or equal to the preset pressure, sending a first gas regulation compensation signal to the gas preparation power supply device so as to reduce the gas preparation acceleration of the oxyhydrogen preparation device.
In this embodiment, the separation pressure is an internal air pressure of the gas storage bin, and specifically, the separation pressure is a pressure on an air outlet diaphragm of the gas storage bin. In the process of preparing gas by the hydrogen and oxygen preparation device through electrolysis, hydrogen and oxygen enter the corresponding gas storage bins for storage, the gas outlet diaphragm is positioned at the gas outlet of the gas storage bins and is extruded by the gas, so that the separation pressure is used for reflecting the pressure when the gas in the gas storage bins is stored, and the pressure on the gas outlet diaphragm is obtained through the corresponding gas pressure sensor. The separation pressure is the real-time air pressure of the air in the air storage bin, and the separation pressure is used for displaying the current pressure on an air outlet diaphragm in the air storage bin, namely the separation pressure is used for displaying the current pressure of the air in the air storage bin. The preset pressure is the maximum air pressure of the gas stored in the gas storage bin, namely the preset pressure is the maximum air pressure which can be borne by the gas outlet diaphragm in the gas storage bin, namely the preset pressure is the corresponding air pressure when the gas in the gas storage bin is excessive. Thus, the separation pressure is greater than or equal to the preset pressure, which indicates that the current air pressure of the gas in the gas storage bin is greater than the standard air pressure, i.e., indicates that the current air pressure of the gas in the gas storage bin reaches or greatly exceeds the maximum air pressure which can be borne by the gas diaphragm, i.e., indicates that the current volume of the gas in the gas storage bin is greater than the maximum gas storage volume, and at this time, the gas in the gas storage bin is in an excessive amount, and simultaneously indicates that the gas preparation rate of the oxyhydrogen preparation device is greater than the gas outlet rate. In this way, a first gas regulation compensation signal is sent to the gas production power supply device, and the first gas regulation compensation signal regulates the gas regulation signal, for example, the increase rate of the gas production speed of the oxyhydrogen production device is reduced, that is, the increase amount of the gas production speed of the oxyhydrogen production device is reduced, so that the increase of the gas production speed of the oxyhydrogen production device is slowed, specifically, the increase amount of the increase rate of the electrolytic current output by the gas production power supply device is reduced, so that the increase amount of the gas production speed of the oxyhydrogen production device is reduced, and further, the gas excess probability of the oxyhydrogen production device is reduced, thereby effectively reducing the gas production excess probability of the oxyhydrogen production device, and simultaneously, the power consumption of the oxyhydrogen production device can also be reduced.
Furthermore, in the long-term electrolysis process of the oxyhydrogen preparation device, calcified particles mixed with hydrogen or oxygen are easily generated, so that the calcified particles are easily guided to the through holes on the gas outlet diaphragm along with gas and then are easily attached to the inner wall of the through holes on the gas outlet diaphragm, the aperture of the through holes on the gas outlet diaphragm is reduced, the separation pressure of the gas outlet diaphragm is easily and quickly subjected to overpressure, namely, the induction accuracy of the separation pressure is reduced, and the gas pressure in the gas storage bin is misjudged.
In order to reduce the erroneous judgment probability of excessive gas waste, when the separation pressure is greater than or equal to the preset pressure, a first gas regulation compensation signal is sent to the gas production power supply device to reduce the gas production acceleration of the oxyhydrogen production device, and then the method further comprises the following steps:
acquiring the temperature of a storage cavity of the gas storage bin;
detecting whether the temperature of the storage cavity is greater than or equal to a preset cavity temperature;
and when the temperature of the storage cavity is greater than or equal to the preset cavity temperature, sending a second gas adjusting compensation signal to the gas making power supply device so as to reduce the second-order acceleration of the gas preparation of the oxyhydrogen preparation device.
In this embodiment, when the separation pressure is higher than a standard pressure, that is, the pressure in the gas storage bin is higher than the maximum pressure that the gas outlet diaphragm can bear, the temperature of the storage cavity in the gas storage bin needs to be detected, where the temperature of the storage cavity is the current temperature of the gas in the gas storage bin, and the temperature of the storage cavity is used to reflect the effect of heat exchange between the gas in the gas storage bin and the external gas. The preset cavity temperature is the corresponding cavity temperature when the gas in the gas storage cavity and the gas of the external environment perform normal rate heat exchange, and the preset cavity temperature is used as the standard temperature of the gas in the gas storage cavity and is used for comparing the current temperature of the gas in the gas storage cavity. The temperature of the storage cavity is greater than or equal to the preset cavity temperature, which indicates that the temperature of the gas in the gas storage cavity is too high, i.e. that the heat exchange rate between the gas in the gas storage cavity and the external gas is too low, i.e. that the amount of the gas in the gas storage cavity is excessive. Thus, at this time, a second gas regulation compensation signal is sent to the gas production power supply device, and the second gas regulation compensation signal is used for adjusting the rate increase amount of the first gas regulation compensation signal, specifically, the second gas regulation compensation signal is used for reducing the second-order acceleration of the gas preparation of the oxyhydrogen preparation device, that is, the derivative of the second gas regulation compensation signal to the gas preparation acceleration corresponding to the first gas regulation compensation signal is reduced, so that the gas preparation acceleration of the oxyhydrogen preparation device is changed, the gas preparation acceleration of the oxyhydrogen preparation device is reduced, the gas preparation rate of the oxyhydrogen preparation device is further reduced, and the gas preparation rate of the oxyhydrogen preparation device is effectively reduced as soon as possible. Wherein the acceleration of the gas production rate and the decrease of the second-order acceleration are to gradually intensify the decrease of the gas production rate, rather than directly stop the gas production of the oxyhydrogen production apparatus, which is still required to produce gas after all.
Furthermore, the casing of the oxyhydrogen preparation device is made of plastic, so that the heat insulation performance is poor, the temperature in the gas storage bin is easily influenced by the external environment, namely, the gas in the gas storage bin is easily subjected to heat exchange, and therefore, in the environment with higher temperature, the temperature in the storage cavity is easily influenced by the external environment, and the condition that the gas in the gas storage bin is excessive is misjudged.
In order to further reduce the probability of misjudgment, the method for detecting whether the temperature of the storage cavity is greater than or equal to a preset cavity temperature further comprises the following steps:
obtaining the external surface environment temperature of the oxyhydrogen preparation device;
carrying out cavity-ring temperature compensation treatment on the outer surface ring temperature and the storage cavity temperature to obtain cavity-ring temperature compensation quantity;
detecting whether the cavity ring temperature compensation quantity is matched with a preset temperature compensation quantity or not;
and when the cavity ring temperature compensation quantity is matched with the preset temperature compensation quantity, sending a warmer signal to the oxyhydrogen preparation monitoring system so as to adjust the preset cavity temperature.
In this embodiment, the external surface environment temperature is the temperature of the environment where the housing of the oxyhydrogen preparation device is located, and specifically, an environment temperature sensor is disposed on the housing of the oxyhydrogen preparation device and is used for sensing the external surface environment temperature. The gas storage chamber is characterized in that the temperature of the storage chamber is the temperature of gas in the gas storage chamber, the surface ring temperature and the storage chamber temperature are subjected to chamber ring temperature compensation treatment, the temperature of the gas in the gas storage chamber is compared with the external environment temperature, so that the difference between the temperature of the gas in the gas storage chamber and the external environment temperature is obtained, namely the temperature difference between the temperature of the gas in the gas storage chamber and the external environment temperature is obtained, and the chamber ring temperature compensation quantity is also obtained. The preset temperature compensation amount is a temperature difference range between the gas temperature in the gas storage bin and the external environment temperature, namely the preset temperature compensation amount is the inter-cell temperature difference between the gas temperature in the gas storage bin and the external environment temperature. The cavity ring temperature compensation quantity is matched with the preset temperature compensation quantity, so that the fact that the difference between the gas temperature in the gas storage bin and the external environment temperature is too small is shown, that is, the fact that the gas temperature in the gas storage bin is equivalent to the external environment temperature is shown, that is, the fact that the gas temperature in the gas storage bin is influenced by the external environment temperature is shown, at the moment, the difference exists between the temperature of the storage cavity in the gas storage bin and the actual temperature of the gas in the gas storage bin, the preset cavity temperature needs to be updated, accurate judgment of the temperature of the storage cavity is guaranteed, and therefore the misjudgment probability of the condition that the gas in the gas storage bin is excessive is reduced.
In another embodiment, the sending a warmer signal to the oxyhydrogen production monitoring system to adjust the preset cavity temperature comprises the following steps:
detecting whether the temperature of the storage cavity is greater than or equal to a first preset cavity temperature;
when the temperature of the storage cavity is greater than or equal to the first preset cavity temperature, a first temperature-raising signal is sent to an oxyhydrogen preparation monitoring system so as to increase the preset cavity temperature. And increasing the temperature of the preset cavity under the high-temperature environment, so that the temperature judgment standard of the temperature of the storage cavity is increased, and the erroneous judgment probability of excessive gas is reduced.
Whether the temperature of the storage cavity is larger than or equal to a first preset cavity temperature or not is detected, and then the method further comprises the following steps:
when the temperature of the storage cavity is lower than the first preset cavity temperature, detecting whether the temperature of the storage cavity is higher than or equal to a second preset cavity temperature;
and when the temperature of the storage cavity is greater than or equal to the second preset cavity temperature, sending a second temperature-raising signal to the hydrogen and oxygen preparation monitoring system so as to reduce the preset cavity temperature. And the second preset cavity temperature is lower than the first preset cavity temperature and is in a low-temperature environment at the moment, and the preset cavity temperature is reduced, so that the temperature judgment standard of the storage cavity temperature is reduced, and the misjudgment probability of excessive gas is reduced.
Furthermore, when the gas in the gas storage bin is stored, part of moisture in the electrolytic medium in the electrolytic bin is mixed with the gas and then stored in the gas storage bin, and once the gas in the gas storage bin is excessive, the water drops are condensed on the diaphragm between the gas storage bin and the electrolytic bin, so that the gas in the electrolytic bin cannot be smoothly introduced into the gas storage bin, the gas pressure in the electrolytic bin is easily too high, and the probability of explosion of the electrolytic bin is easily increased.
In order to reduce the probability of explosion of the electrolytic bin when the electrolysis is excessive, when the separation pressure is greater than or equal to the preset pressure, a first gas regulation compensation signal is sent to the gas production power supply device to reduce the gas production acceleration of the oxyhydrogen production device, and then the method further comprises the following steps:
acquiring the humidity of a storage cavity of the gas storage bin;
detecting whether the humidity of the storage cavity is larger than the preset cavity humidity;
and when the humidity of the storage cavity is greater than the humidity of the preset cavity, sending a signal of forbidding to the gas preparation power supply device to stop supplying power to the oxyhydrogen preparation device.
In this embodiment, the separation pressure is higher than the standard pressure, that is, the air pressure in the air storage chamber is higher than the maximum air pressure that the air outlet diaphragm can bear, and at this time, the humidity of the storage chamber in the air storage chamber needs to be detected, where the humidity of the storage chamber is the current humidity in the air storage chamber, and the humidity of the storage chamber is used to indicate whether the moisture in the air storage chamber is too much. The preset cavity temperature is the corresponding cavity humidity when water molecules in the gas storage cavity are condensed into water drops and plug the through hole in the diaphragm between the electrolysis chamber and the gas storage chamber, and the preset cavity temperature is used as the standard humidity in the gas storage cavity and is used for comparing the current humidity in the gas storage cavity. The humidity of the storage cavity is greater than or equal to the preset cavity temperature, which indicates that the humidity in the storage cavity is too high, i.e. that water drops on the diaphragm in the storage cavity are too much, i.e. that the amount of water drops formed by condensation in the storage cavity is excessive. Thus, at this time, a no-solution signal is sent to the gas making and supplying device, the no-solution signal is used for carrying out rate adjustment on the first gas adjusting compensation signal, specifically, the no-solution signal is used for reducing the gas making rate of the oxyhydrogen preparation device to 0, so that the water molecule generation rate of the oxyhydrogen preparation device is reduced, the oxyhydrogen preparation device is prohibited to continue to prepare gas, and an alarm is given out to avoid the situation that the electrolytic bin bursts.
Still further, when the humidity in the gas storage bin is lower than the preset chamber humidity, the electrolysis bin continuously introduces gas into the gas storage bin, and when the electrolytic medium in the electrolysis bin is too little, the electrolysis pole piece is easy to dry burn, although moisture is not generated, that is, the chamber humidity of the gas storage bin can be ensured to be below the preset chamber humidity, at this time, the electrolysis pole piece in the electrolysis bin will be damaged.
In order to reduce the dry burning probability of the electrolytic bin, whether the humidity of the storage cavity is greater than the preset humidity of the storage cavity is detected, and then the method further comprises the following steps:
acquiring a liquid optical signal of the electrolytic bin;
acquiring a liquid light refraction value according to the liquid light signal;
detecting whether the liquid light refraction value is matched with a preset refraction value or not;
and when the liquid light refraction value is not matched with the preset refraction value, sending a low-liquid early warning signal to the gas-making power supply device so as to stop the gas-making power supply device.
In this embodiment, the liquid optical signal is an optical signal received by an optical liquid level sensor in the electrolytic cell, for example, the electrolytic cell has at least one set of optical liquid level detecting components connected to its inner wall, and the optical liquid level detecting components include an optical liquid level emitting element and an optical liquid level receiving element. The optical liquid level emitting piece is arranged opposite to the optical liquid level receiving piece, the optical liquid level emitting piece is used for facing the area where the optical liquid level receiving piece is located to emit optical detection signals, and the optical liquid level receiving piece is used for receiving the optical detection signals. When the liquid level is normal and the liquid level is low, the optical detection signal received by the optical liquid level receiving part changes, namely, when the liquid level is normal and the liquid level is low, the optical detection signal received by the optical liquid level receiving part changes suddenly, so that the low liquid level condition in the electrolytic bin can be determined conveniently. The liquid light refraction value corresponds to the liquid level in the electrolytic bin in real time, namely the liquid light refraction value is the real-time light perception value of the liquid light signal, namely the liquid light refraction value corresponds to the real-time liquid level in the electrolytic bin. The preset refraction value is a liquid light refraction value corresponding to the safety warning liquid level in the electrolytic bin, and the liquid light refraction value is not matched with the preset refraction value, so that the change of an optical detection signal received by an optical liquid level receiving device in the electrolytic bin is indicated, that is, the current liquid level in the electrolytic bin is lower than the safety warning liquid level, that is, the current liquid level in the electrolytic bin is too low. Therefore, at the moment, the liquid level of the electrolytic medium in the electrolytic bin is too low, which indicates that the electrolytic medium in the electrolytic bin is too little, and a low-liquid early warning signal is sent to the gas-making power supply device to shut down the gas-making power supply device, so that the probability of dry burning of the positive and negative pole pieces in the electrolytic bin is effectively avoided.
