Description
Technical Field
The present disclosure relates to the field of state detection technologies for deionized water and ion filters, and more particularly, to a method and an apparatus for monitoring a replacement state of a deionized water and an ion filter.
Background
A fuel cell is a chemical device that directly converts chemical energy of fuel into electric energy, and is also called an electrochemical generator, which is a fourth power generation technology following hydroelectric power generation, thermal power generation, and atomic power generation. It has been used in automobiles and the like.
The removed water in the fuel cell needs to be replaced in time when the conductivity is too high so as to ensure the normal use of the fuel cell. Therefore, the ion filter for filtering the deionized water also needs to be replaced in time when the filtering effect of the ion filter is deteriorated, otherwise, the conductivity of the deionized water is easily increased rapidly, and thus the fuel cell cannot be used normally. In the prior art, the replacement state of the deionized water and the ion filter is determined by detecting the conductivity of the deionized water in real time and judging whether the conductivity of the deionized water is higher than a preset value, and if the conductivity of the deionized water is higher than the preset value, the deionized water and the ion filter are replaced at the same time.
However, the over-high conductivity of the deionized water may be caused by the over-long usage time of the deionized water, or may be caused by the fact that the ion filter is not replaced in time after the filtering effect of the ion filter is deteriorated. Therefore, in the prior art, the conductivity of the deionized water is too high, and most of the conductivity is caused by the fact that the filtering capacity of the ion filter cannot be determined, so that the ion filter cannot be replaced in time. Therefore, when the conductivity of the deionized water is judged to be higher than the preset value, only the deionized water and the ion filter can be replaced at the same time. The existing method requires frequent replacement of both the deionized water and the ion filter, which is time consuming and also makes maintenance of the fuel cell cost prohibitive.

Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

An embodiment of the present application provides a method for monitoring a replacement state of a deionized water and an ion filter, as shown in fig. 1, including:
and S101, acquiring state data corresponding to the work cycle.
Wherein, the engine water pump of the fuel cell starts to work to finish as a work cycle. The status data includes a starting conductivity and an ending conductivity of the deionized water. The initial conductivity is the conductivity of the deionized water at the time the engine water pump begins to operate. The end conductivity is the conductivity of the deionized water at the time when the engine water pump ends operation.
Specifically, at the time when the engine water pump is just started, the conductivity of the deionized water at the current time is recorded and collected through the fuel cell engine controller FCU, and the initial conductivity of the state data corresponding to the current working cycle is obtained. Then, at the time of closing the engine water pump, the conductivity of the deionized water at the current time is also recorded and acquired by the fuel cell engine controller FCU, and the ending conductivity of the state data corresponding to the current working cycle is obtained, so that the state data corresponding to one working cycle is obtained, and the obtained state data is stored.
S102, dividing the number of the failure state data in the target state data by the total number of the state data in the target state data to obtain failure rate.
The end conductivity in the failure state data is not less than the initial conductivity, that is, if the end conductivity of one state data is greater than or equal to the initial conductivity, it indicates that the ion filter cannot filter the deionized water well in the working period corresponding to the state data, so that the state data is defined as the failure state data.
The target state data includes: the state data corresponding to the work cycle of this time and the state data corresponding to a plurality of historical work cycles. It should be noted that the target state data mentioned in the embodiment of the present application refers to state data in state data acquired for currently used deionized water and ion filter, and is not a state in all state data acquired previously. Therefore, when at least one of the deionized water and the ion filter is replaced, the previously acquired state data does not belong to the acquired data, and the state data acquired after the replacement does belong to the target state data. Optionally, in order to be able to detect quickly when the ion filter fails, the target state data is generally the state data corresponding to the current working cycle and the state data corresponding to a plurality of historical working cycles closest to the current working cycle.
Alternatively, the failure status data generally does not occur during the initial use of the DI water and the ion filter, so that there is no concern of an excessive failure rate during the initial use of the DI water and the ion filter. For example, it is assumed that the status data acquired for the first time is failure status data, and the failure rate is one hundred percent. Of course, in order to avoid the contingency, it may be determined whether the number of target state data is greater than the preset number before the step S102 is executed, and the step S102 is executed when the number of target state data is greater than the preset data amount.
S103, judging whether the failure rate is smaller than a preset replacement value or not.
The preset replacement value can also be set according to the replacement requirement of the ion filter. Since the ion filter is replaced more frequently the larger the preset replacement value is, the preset replacement value is usually set to a value approximately equal to 1, for example, 0.96 or 0.98, etc. Therefore, when the failure rate is not less than the preset replacement value, that is, the failure rate is greater than or equal to the preset replacement value, it indicates that ions cannot be filtered out well in a plurality of recent working cycles of the ion filter, and therefore it indicates that the ion filter needs to be replaced.
It should be noted that when the failure rate is determined to be not less than the preset replacement value, the replacement state of the ion filter may be directly prompted as a recommended replacement, and in the subsequent step S104, it is determined that the initial conductivity in the state data corresponding to the current working cycle is not less than the preset normal conductivity, and then the replacement state of the deionized water is separately prompted as a recommended replacement. Of course, the ion filter may be prompted after the step S104 is performed, as in the present embodiment, so that the replacement states of the ion filter and the deionized water may be prompted at the same time. In this embodiment, step S104 is performed after determining that the failure rate is not less than the preset replacement value.
And S104, judging whether the initial conductivity in the state data corresponding to the work period is smaller than the preset normal conductivity.
It should be noted that the preset normal conductivity indicates whether the conductivity of the deionized water is too high.
Since the initial conductivity in the state data corresponding to the current working cycle is the conductivity of the deionized water before working and has not been filtered by the ion filter, the conductivity is the actual conductivity of the current deionized water. Therefore, whether the conductivity of the deionized water is too high is determined by judging whether the initial conductivity in the state data corresponding to the work period is smaller than the preset normal conductivity.
Specifically, if it is determined that the initial conductivity in the state data corresponding to the current duty cycle is smaller than the preset normal conductivity, it indicates that the conductivity of the deionized water is not out of standard and the deionized water can be used normally, so step S105 is executed at this time. If the initial conductivity in the state data corresponding to the current working cycle is determined to be not less than the preset normal conductivity, it indicates that the conductivity of the deionized water exceeds the standard and needs to be replaced, so step S106 is executed at this time.
It should be noted that, in the present application, it is not limited to execute step S104, then execute step S105, and finally execute step S105 or step S106. Step S104 and step S105 are performed simultaneously, and then step S105 or step S106 is performed accordingly. Step S105 may be executed first, and then step S104 may be executed.
And S105, prompting that the replacement state of the ion filter is recommended to be replaced.
Optionally, the replacement state of the ion filter is indicated as recommended replacement on the display interface, and the replacement state of the deionized water is not indicated, so that the deionized water does not need to be replaced if the replacement state of the deionized water is not seen. Of course, other replacement states of the DI water may be prompted to inform the user that the DI water may be replaced differently.
S106, prompting that the replacement state of the ion filter is replacement recommended, and prompting that the replacement state of the deionized water is replacement recommended.
Specifically, the replacement state of the ion filter is displayed as recommended replacement on the display interface, and the replacement state of the deionized water is displayed as recommended replacement.
According to the method for monitoring the replacement state of the deionized water and the ion filter, the state data of the working period is obtained by obtaining the initial conductivity of the deionized water at the moment when the engine water pump starts to work and the ending conductivity of the deionized water at the moment when the engine water pump ends to work. Since the initial conductivity is typically greater than the end conductivity when the filtration capacity of the ion filter is normal. It is possible to define the state data in which the end conductivity is not less than the start conductivity as failure data and then determine whether the ion filter needs to be replaced by the failure rate obtained by dividing the number of failure state data in the target state data by the total number of state data in the target state data. Since the initial conductivity is the conductivity of the deionized water in a non-working state, whether the deionized water needs to be replaced can be determined by whether the initial conductivity is greater than a preset normal conductivity rate. Therefore, when the failure rate is judged to be not less than the preset replacement value and the initial conductivity in the state data corresponding to the work cycle is judged to be less than the preset normal conductivity, the replacement state of the ion filter is prompted to be the replacement recommendation. And if the failure rate is judged to be not less than the preset replacement value and the initial conductivity in the state data corresponding to the work cycle is judged to be not less than the preset normal conductivity, prompting that the replacement state of the ion filter is recommended replacement and prompting that the replacement state of the deionized water is recommended replacement. Therefore, the replacement states of the deionized water and the ion filter are detected simultaneously, the phenomenon that the conductivity of the deionized water is too high due to the fact that the ion filter is not replaced timely is avoided, the deionized water and the ion filter are not required to be replaced simultaneously, frequent replacement of the deionized water and the ion filter is avoided, and the problems that time is consumed and cost is too high in the prior art are solved.
Another embodiment of the present application provides a method for monitoring a replacement state of a deionized water and ion filter, as shown in fig. 2, including:
s201, obtaining the using time of the deionized water and the using time of the ion filter.
S202, judging that the service time of the deionized water does not exceed a first service life and the service time of the ion filter does not exceed a second service life.
Note that, step S202 may also be expressed as: and respectively judging whether the service time of the deionized water exceeds a first service life and judging whether the service time of the ion filter exceeds a second service life.
In particular, consider the case where a detected conductivity signal may fail. In the embodiment of the application, whether the deionized water and the ion filter need to be replaced or not is further determined by the service time of the deionized water and the ion filter respectively.
Therefore, the lifetime of the deionized water may be empirically preset, i.e., set as the first lifetime, and the lifetime of the ion filter may be empirically set, i.e., set as the second lifetime. Timers for deionized water and ion filter usage time may then be utilized when the fuel cell is first used or the deionized water or ion filter is replaced, respectively.
Optionally, another embodiment of the present application provides a system for monitoring a replacement state of a deionized water and ion filter, as shown in fig. 3, which mainly includes a fuel cell engine controller FCU and a display meter. Besides displaying the deionized water and the replacement state of the ion filter acquired by the fuel cell engine controller FCU on the display instrument, the use time of the ion filter and the use time of the deionized water can be acquired by the fuel cell engine controller FCU respectively and output to the display instrument for display. And the conductivity of the deionized water can be obtained in real time and displayed on a display instrument, so that a user can know the conductivity of the deionized water in real time.
Step S202 is not limited to be executed before step S203, and may be determined in real time. However, in order to directly indicate that the replacement state of the deionized water is recommended when it is determined that the usage time of the deionized water exceeds the first usage period and/or directly indicate that the replacement state of the ion filter is recommended when it is determined that the usage time of the ion filter exceeds the second usage period, the ion filter is not used in step S202, so that the embodiment of the present application performs step S202 before step S203. Therefore, in the embodiment of the present application, if it is determined that the usage time of the deionized water does not exceed the first usage period and it is determined that the usage time of the ion filter does not exceed the second usage period, step S203 is executed.
And S203, acquiring the state data corresponding to the work cycle.
Wherein the status data comprises a starting conductivity and an ending conductivity of the deionized water. The initial conductivity is the conductivity of the deionized water at the moment when the engine water pump starts to work, and the ending conductivity is the conductivity of the deionized water at the moment when the engine water pump ends to work.
It should be noted that, in the specific implementation of step S203, reference may be made to step S101 in the foregoing method embodiment, and details are not described here again.
S204, dividing the number of the failure state data in the target state data by the total number of the state data in the target state data to obtain failure rate.
Wherein the end conductivity in the failure status data is not less than the starting conductivity. The target state data includes: the state data corresponding to the work cycle of this time and the state data corresponding to a plurality of historical work cycles.
It should be noted that, in the specific implementation of step S204, reference may be made to step S102 in the foregoing method embodiment, and details are not described here again.
S205, judging whether the failure rate is larger than a preset normal value.
Wherein the predetermined normal value is less than a smaller value of the predetermined replacement value for indicating that the ion filter and the deionized water are both in a relatively good condition.
Therefore, if it is determined that the failure rate is not greater than the preset normal value, step S206 is executed without continuing the subsequent steps, so that the load on the fuel cell engine controller FCU can be reduced.
If the failure rate is greater than the predetermined normal value, step S207 is executed.
S206, prompting that the replacement state of the ion filter is a normal state and prompting that the replacement state of the deionized water is a normal state.
S207, comparing the size relation between the failure rate and a preset replacement value, and comparing the size relation between the initial conductivity in the state data corresponding to the work cycle and the preset normal conductivity to obtain a comparison result.
Step S207 may also be understood as: and respectively judging whether the failure rate is smaller than a preset replacement value or not, and judging whether the initial conductivity in the state data corresponding to the work cycle is smaller than a preset normal conductivity or not to obtain a judgment result.
And S208, respectively prompting the replacement state of the ion filter and the replacement state of the deionized water based on the comparison result.
Step S208 can also be understood as: and respectively prompting the replacement state of the ion filter and the replacement state of the deionized water based on the judgment result.
Specifically, if the failure rate is determined to be not less than the preset replacement value and the initial conductivity in the state data corresponding to the current working period is determined to be less than the preset normal conductivity, it is determined that the filtering effect of the ion filter cannot meet the requirement and needs to be replaced, but the conductivity of the deionized water does not exceed the standard when the deionized water is not in operation, and the deionized water can be used continuously. Therefore, the replacement state of the ion filter is prompted to be recommended, and the replacement state of the deionized water is prompted to be a normal state, so that the user can replace the ion filter.
If the failure rate is judged to be smaller than the preset replacement value and the initial conductivity in the state data corresponding to the work period is judged to be smaller than the preset normal conductivity, the condition that the ion filter does not reach the condition to be replaced is indicated, and ion filtering can be carried out. Since the conductivity of the deionized water is also relatively low, the replacement state of the deionized water is indicated as a normal state.
If the failure rate is judged to be smaller than the preset replacement value and the initial conductivity in the state data corresponding to the work period is judged to be not smaller than the preset normal conductivity, the ion filter can still be normal, and the conductivity of the deionized water exceeds the standard, but the ion filter can filter the ions of the deionized water during work, so that the conductivity of the deionized water is reduced, the normal use of the fuel cell is ensured, the replacement state of the ion filter is prompted to be the alarm state, and the replacement state of the deionized water is prompted to be the alarm state.
If the failure rate is judged to be not less than the preset replacement value and the initial conductivity in the state data corresponding to the work period is judged to be not less than the preset normal conductivity, the ion filter cannot be normally filtered and the conductivity of the deionized water exceeds the standard, so that the ion filter and the deionized water both need to be replaced to ensure the normal use of the fuel cell, and the replacement state of the ion filter is prompted as the replacement suggestion at the moment and the replacement state of the deionized water is prompted as the replacement suggestion.

S402, resetting the timer corresponding to the target object.
The timer is used for recording the use time of the corresponding target object.
Since the embodiment of the application also determines whether the ion filter and the deionized water need to be replaced or not through the service life of the ion filter and the deionized water, the timer needs to be reset correspondingly when the ion filter and the deionized water are replaced.
Alternatively, the timer may be reset after the target object is detected to be replaced. The reset may also be performed when a user triggers a reset instruction.
