In order to monitor and early warn the hydrogen concentration in a limited space, the existing method generally arranges a large number of hydrogen detection devices in the limited space to detect the hydrogen concentration and early warn when the hydrogen concentration is detected to be too high. Or, the early warning is carried out manually by means of personnel supervision records.
However, when the early warning is performed based on the hydrogen gas detection apparatus, a serious hydrogen gas leakage event may have occurred in a limited space. And, adopt the manual mode to carry out the early warning, then the cost of labor is higher, and there is probably that personnel's safety consciousness is low, supervise the influence such as idle, make the hydrogen concentration in the limited space exist great uncertainty.
Based on this, in order to reasonably perform early warning on the change of the hydrogen concentration, the embodiment of the application provides a hydrogen early warning method, which can be applied to terminal devices such as a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook and the like, or can be applied to detection devices such as a hydrogen detector and the like, and the embodiment of the application does not limit the specific types of the terminal devices.
Referring to fig. 1, fig. 1 shows a flowchart of an implementation of a hydrogen early warning method according to an embodiment of the present application, where the method includes the following steps:
s101, acquiring a plurality of historical hydrogen concentrations during detection of a preset monitoring area in a target time period.
In an embodiment, the monitoring area may be an area where a storage device storing hydrogen gas is located. In one monitoring area, one or more detection devices for monitoring the hydrogen concentration can be arranged. In addition, the model number of each detection device may be the same or different, and this is not limited.
The detection equipment comprises a plurality of portable hydrogen detectors, pumping type hydrogen detectors, online hydrogen detectors and the like, and is not limited to the portable hydrogen detectors.
When the detection device has a plurality of detection devices, a plurality of hydrogen concentrations can be detected at any one time. At this time, the terminal device may determine an average value of the plurality of hydrogen concentrations as the hydrogen concentration that eventually corresponds to the time.
The target time period may be set in advance by a worker, or may be determined according to a historical hydrogen concentration at a historical time, which is not limited.
For example, when the hydrogen early warning method of the present example is executed, if the hydrogen concentration in the monitoring area is too high, for example, the hydrogen concentration is greater than a preset early warning value, the terminal device generates early warning information and sends the early warning information to the preset early warning terminal. At this time, when the worker determines that the early warning information is received based on the early warning terminal, the worker usually detects and maintains the storage device in the monitoring area to check whether a leakage event occurs in the storage device. While reducing the hydrogen concentration in the monitored area. For example, by means of ventilation, a long accumulation of hydrogen in a confined space is avoided.
Based on this, when selecting the target time period, the terminal device may first determine the last two target times before the current time. The historical hydrogen concentration corresponding to each target moment is larger than a preset early warning value. That is, the timing when the warning information is generated twice is selected. At this time, after the early warning information is generated for the first time, the staff detects and maintains the storage device of the monitoring area, and reduces the hydrogen concentration in the monitoring area. Therefore, at various time points after the early warning information is generated for the first time, the hydrogen concentration detected by the detection device can be considered, and the normal change of the hydrogen concentration in the monitoring area can be generally represented when the undamaged storage device (the storage device does not have a leakage event) works.
And then, when the early warning information is generated for the second time, the storage equipment can be considered to be possibly leaked, so that the hydrogen concentration in the monitoring area is higher than a preset early warning value. Therefore, the hydrogen concentration detected by the detection device can be considered at each time point between the first generation of the early warning information and the second generation of the early warning information, and can generally represent the normal change of the hydrogen concentration in the monitoring area when the undamaged storage device works, and the abnormal change of the hydrogen concentration in the monitoring area when the undamaged storage device has a leakage event.
It will be appreciated that the time period between the two target times may be considered as a target time period, and the plurality of historical hydrogen concentrations within the target time period may be obtained, not only to characterize the change in hydrogen concentration when the storage device is normal, but also when the storage device is gradually abnormal (a leakage event occurs gradually). Based on this, it can be considered that a plurality of historical hydrogen concentrations in the target period of time can be used to predict whether a leak event has occurred in the storage device in a later period of time.
In this embodiment, two times closest to the current time are selected to be determined as target times. Therefore, in the subsequent prediction process, the prediction accuracy is higher.
It should be noted that selecting the two target time periods closest to the current time is only one example in the present embodiment. In other embodiments, the target time period may be randomly selected, without limitation.
In another embodiment, if the time period between the two target moments is less than the preset interval duration, the time of the two occurrence of the early warning may be considered to be close. At this time, when the period between the two target times is determined as the target period, the accuracy thereof for making the subsequent predictions may be low. Based on this, the target time with the latest time (closest to the current time) of the two target times may be reserved, and another target time closest to the current time may be redetermined according to the time sequence until the time period between the target time and the target time with the latest time is determined to be greater than or equal to the preset interval duration.
Illustratively, for an A-target time and a B-target time, the A-target time is earlier than the B-target time (i.e., the B-target time is closer to the current time). If the time period between the target time A and the target time B is smaller than the preset interval duration, the target time B with the latest time can be reserved. And simultaneously, determining another C target moment closest to the current moment. And then, when the time period between the C target time and the B target time is greater than or equal to the preset interval duration, determining the time period as a target time period.
S102, generating a change curve of the hydrogen concentration according to each historical hydrogen concentration.
In one embodiment, the change curve is a curve generated according to the historical hydrogen concentration, and may be used to characterize the change of the hydrogen concentration when the storage device is normal, and the change of the hydrogen concentration when the storage device is gradually abnormal (a leakage event occurs gradually).
The change curve may be generated based on a regression analysis method or a graph correlation analysis method, and in this embodiment, the manner of generating the change curve is not limited. By way of example, the change curve may be a curve generated based on a time difference and a historical hydrogen concentration. The time difference may be a difference between a history time corresponding to the history hydrogen concentration and an earliest target time in the target time period.
It should be noted that, in order to be able to generate a change curve that meets the actual situation, the number of the historical hydrogen concentrations in the target period should be larger than the preset number. Based on this, if the number of the historical hydrogen concentrations is smaller than the preset number, the terminal device may select the other two target moments as the target time periods.
The detection device can monitor the hydrogen concentration once every preset time. Thus, the expected interval period required to collect the preset number of hydrogen concentrations may be predetermined. Based on this, when the time period between the last two target times is smaller than the predicted interval time period, the other two target times may be selected as target time periods. Otherwise, when the time length between the last two target moments is greater than or equal to the expected interval time length, the target time length is directly determined.
S103, acquiring the actual hydrogen concentration at the current time.
In an embodiment, the actual hydrogen concentration at the current time may be determined by the above-described detection device, and then uploaded to the terminal device by the detection device, which will not be described in detail.
And S104, if the actual hydrogen concentration meets the preset early warning condition according to the change curve, generating early warning information.
In one embodiment, the described variation profile may characterize the variation in hydrogen concentration when the storage device is normal, as well as the variation in hydrogen concentration when the storage device is gradually abnormal (a leakage event occurs gradually). Therefore, based on the actual hydrogen concentration at the current time, it can be determined whether the current actual hydrogen concentration satisfies a preset predicted condition, for example, whether the hydrogen concentration change when the storage device gradually experiences a leakage event is satisfied, so as to determine whether to perform early warning.
Specifically, the terminal device may predict, according to the change curve, the predicted hydrogen concentrations respectively corresponding to the respective moments after the target time period. And then, determining the target predicted hydrogen concentration corresponding to the current moment from the plurality of predicted hydrogen concentrations. And then, generating an early warning result corresponding to the early warning condition according to the target predicted hydrogen concentration and the actual hydrogen concentration.
In one embodiment, since the change curve is a curve generated based on the time difference and the historical hydrogen concentration, the difference between the current time and the latest target time in the target time period can be calculated when predicting the hydrogen concentration at the current time. And substituting the difference value into a change curve to determine the target predicted hydrogen concentration corresponding to the difference value. In the present embodiment, the manner of obtaining the predicted hydrogen concentration at the current time based on the change curve is not limited.
In one embodiment, the terminal device may calculate a concentration difference between the actual hydrogen concentration and the target predicted hydrogen concentration. And then, when the actual hydrogen concentration is larger than the target predicted hydrogen concentration and the concentration difference is larger than the first preset concentration difference, determining that the actual hydrogen concentration meets the preset early warning condition as the early warning result.
When the actual hydrogen concentration is greater than the target predicted hydrogen concentration, the terminal device may consider that the hydrogen concentration change between the last target time of the target time period in the monitoring area and the current time is beyond expectations. Therefore, the storage device can be considered to have a leakage event, and the early warning result is determined to be that the actual hydrogen concentration meets the preset early warning condition.
However, in the actual process, there may be an error in the actual hydrogen concentration obtained by the detecting device. Therefore, when determining whether the early warning condition is satisfied, a concentration difference between the actual hydrogen concentration and the target predicted hydrogen concentration needs to be further calculated. And then, when the concentration difference is also larger than the first preset concentration difference, determining that the concentration difference meets the early warning condition.
The first preset concentration difference may be set according to practical situations, which is not limited.
When the actual hydrogen concentration is greater than the target predicted hydrogen concentration, it may be considered that the hydrogen concentration change between the last target time of the target time period and the current time in the monitored area is beyond expectations. However, since the concentration difference is less than or equal to the first preset concentration difference, at this time, the terminal device generally cannot accurately determine whether the actual hydrogen concentration is greater than the target predicted hydrogen concentration, which is caused by the false detection by the detecting device, or by a possible occurrence of a leak event by the storage device.
Based on the above, the terminal device can determine the expected duration of the actual hydrogen concentration reaching the preset early warning value according to the change curve. And then, when the predicted time length is smaller than the preset time length, determining that the actual hydrogen concentration meets the preset early warning condition as the early warning result. That is, determining that the actual hydrogen concentration is greater than the target predicted hydrogen concentration is caused by a leak event of the storage device. Therefore, the terminal device needs to generate the early warning information and send the early warning information to the early warning terminal.
The preset duration may be set according to actual situations, which is not limited.
The change curve is a curve generated based on the time difference and the historical hydrogen concentration. The time difference may be a difference between a history time corresponding to the history hydrogen concentration and an earliest target time in the target time period. Therefore, the terminal device can take the actual hydrogen concentration as input, and perform inverse operation based on the change curve to obtain the corresponding target historical moment in the historical time period. And then, determining the difference value between the target historical time and the last target time in the target time period as the expected duration.
Correspondingly, when the actual hydrogen concentration is smaller than or equal to the target predicted hydrogen concentration, or the predicted time length is longer than or equal to the preset time length, the terminal equipment can determine that the early warning result is that the actual hydrogen concentration does not meet the preset early warning condition. At this time, the terminal device can determine that the hydrogen concentration in the monitoring interval meets the requirement, and only needs to prepare to acquire the actual hydrogen concentration at the next moment for early warning.
The early warning information may include, but is not limited to, one or more information such as an actual hydrogen concentration, a current time or an estimated time length, and the like.
It should be noted that, in another embodiment, if the concentration difference between the actual hydrogen concentration and the preset pre-alarm value is smaller than the second preset concentration difference, the terminal device may consider that the actual hydrogen concentration in the monitoring area is higher as time is accumulated, which may have a potential safety hazard. Based on the method, the terminal equipment can directly generate early warning information so as to early warn the staff in advance and eliminate potential safety hazards.
In this embodiment, a plurality of historical hydrogen concentrations during detection of a preset monitoring area in a target time period are obtained to generate a change curve capable of representing the change of the hydrogen concentration of the monitoring area in the target time period. And then, acquiring the actual hydrogen concentration between the current moments, and generating early warning information when determining that the actual hydrogen concentration meets the preset early warning condition based on the change curve of the generated hydrogen concentration so as to early warn a monitoring area in advance and reduce the safety risk.
In another embodiment, the above described terminal device may predict the predicted hydrogen concentration corresponding to each time point after the target period of time, respectively, based on the change curve. Further, the terminal device may also compare each predicted hydrogen concentration with the corresponding actual hydrogen concentration. If the actual hydrogen concentration of the continuous preset quantity is larger than the predicted hydrogen concentration, the terminal equipment can directly generate early warning information.
It is understood that, for any actual hydrogen concentration, although the actual hydrogen concentration is greater than the target predicted hydrogen concentration at the time, there may be a case where the concentration difference between the actual hydrogen concentration and the target predicted hydrogen concentration at the corresponding time is less than the first preset concentration difference, and the preset time period when the actual hydrogen concentration reaches the preset early warning value is determined to be greater than or equal to the preset duration according to the change curve.
However, when the continuous preset number of actual hydrogen concentrations is greater than the predicted hydrogen concentration, the terminal device may also consider that the actual change in hydrogen concentration in the limited space is greater than the change in each of the historical hydrogen concentrations in the target period. Based on this, in this case, the terminal device may also generate early warning information to improve accuracy of early warning for a limited space.
It is understood that the terminal device may not need to perform any operation if the actual hydrogen concentration of the continuous preset number is less than or equal to the predicted hydrogen concentration.
The preset number may be set according to actual situations, which is not limited. The preset number may be, for example, 3 or 5.
