Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The power source commonly used for supplying power may include: the utility power, the real-time power generation device and the power storage device, and to detection device, in order to detect in real time or detect the object that waits to detect regularly, can connect power supply unit such as utility power or solar panel through the circuit generally, but once the power failure or meet the condition that is unfavorable for the electricity generation such as cloudy day, detection device can be in the outage state, can not realize detecting.
Based on this, this embodiment of the application sets up an electric power storage power supply, such as lead acid battery, lithium ion battery, nickel hydrogen battery, supercapacitor etc. in detection device inside, for detection device realizes supplying power when there is not other power supply.
At least the detection means should comprise: the system comprises a controller, a detection module, an electric power storage power supply, a power switch and an alarm module. The detection module is used for detecting and collecting relevant detection data of an object to be detected and transmitting the relevant detection data to the controller; the alarm module is used for alarming when abnormal data or smaller electric quantity of the stored power supply is detected, so that the effect of reminding workers is achieved.
The controller is used for receiving the related detection data sent by the detection module, analyzing the related detection data and performing other operations so as to intelligently monitor the state of the object to be detected in real time. And most importantly, when the controller detects that the detection device is powered by the power storage power supply only, the controller reasonably distributes the limited power of the power storage power supply, and prolongs the detection duration of the object to be detected.
In the embodiment of the application, the state of the object to be detected may not be changed in real time, or the amplitude of each change is smaller, and the data state of the detected data is stable, so that the data detected in real time are the same data, if the power is continuously supplied in real time, only the electric quantity is consumed, and the abnormal data possibly appearing in the follow-up process is missed. Based on this, the embodiment of the application chooses not to supply power to the detection device in real time, and realizes intermittent power supply to the detection device based on the power supply period.
Referring to fig. 1, a schematic flow chart for implementing a power control method according to an embodiment of the present application may be applied to a controller of a detection device, where the detection device is powered by only the power storage power supply, and the detection device is in a power-off state, the following flow steps are executed, where the flow chart includes:
step S110, obtaining the time when the power switch is controlled last time to make the detection device in the power-on state, and recording the time as the reference time.
And step S120, when the time difference between the current time and the reference time is not smaller than the time corresponding to the power supply period, controlling the power switch to be turned on, so that the detection device is in an electrified state in a preset time period.
The power supply period is obtained after the time length is adjusted according to a preset adjustment rule, wherein the reference power supply period is based on the change speed of detection data of an object to be detected, the reference power supply period is used for controlling the power switch to be turned on for the last time, and the detection device is in an electrified state, and the preset adjustment rule is used for reversely adjusting the reference power supply period according to the change speed.
It can be understood that when the commercial power or the power generation device suddenly fails to supply power to the detection device, the controller immediately controls the power switch to be turned on, so that the detection device is in an electrified state in a preset time period, and the detection module detects and collects data information of an object to be detected as detection data and transmits the detection data to the controller in the preset time period. And the control module performs data analysis based on the detection data and the detection data transmitted by the detection module before the current moment in the preset time period, and determines the change speed of the detection data of the current object to be detected so as to determine the power supply period, thereby determining the moment of starting the power switch next time after the current power supply is finished.
In this embodiment of the present application, considering that there is no commercial power or power supplied by the power generation device, only the electric storage power supplies supply power from beginning to end, so that in order to avoid no referenceable historical detection data in the controller to determine a power supply period, an initial power supply period is preset in the controller, when the electric storage battery is used for the first time, the initial power supply period is used as a control basis of the power switch, and when the collected detection data of the object to be detected is accumulated, the change speed of the detection data can be analyzed, the adjustment is performed on the basis of the initial power supply period, so as to obtain the power supply period of the next control power supply. It will be appreciated that the preliminary power supply period may also be considered as the reference power supply period described above.
The change speed is the speed of detecting data change in unit time, if the change speed is positive, the change trend of the detected data is proved to be positive increase, and the absolute value of the change speed is proved to be the increase amplitude of the detected data in unit time. Similarly, if the change speed is negative, it is proved that the change trend of the detection data is negative decrease, and the absolute value of the change speed is indicative of the decrease amplitude of the detection data in unit time.
It can be understood that for the object to be detected, a data qualified section exists in the detected data, when the change speed of the detected data is positive, it is proved that the current detected data continuously rises, the current detected data is likely to exceed the qualified upper limit value of the data qualified section, and in order to avoid missing the detection of abnormal data, the power supply period is required to be shortened, and the detection frequency is required to be increased. The shortening amplitude of the shortening power supply period can be determined according to the absolute value of the change speed, if the absolute value of the change speed is larger, the adjusting amplitude of the corresponding duration of the power supply period is increased, and if the absolute value of the change speed is smaller, the adjusting amplitude of the corresponding duration of the power supply period can be increased by a small amplitude.
When the change speed of the detection data is negative, the current detection data is proved to continuously drop, the possibility that the detection data exceeds the qualified upper limit value of the data qualified interval is reduced, the power supply period is required to be prolonged, and the detection frequency is reduced. The amplitude of the extended power supply period can be determined according to the absolute value of the change speed, if the absolute value of the change speed is larger, the amplitude of the adjustment of the corresponding duration of the power supply period is increased, and if the absolute value of the change speed is smaller, the amplitude of the adjustment of the corresponding duration of the power supply period can be increased by a small amplitude.
Based on the above, in the embodiment of the present application, the adjustment direction of the reference power supply period is inversely proportional to the change speed of the detection data, and the adjustment amplitude setting of the reference power supply period may be directly proportional to the absolute value of the change speed. According to the embodiment of the application, the detection device can monitor the state of the object to be detected, and the state change trend of the object to be detected can be predicted according to the change speed of the detection data. And the power supply period is adjusted based on the change speed of the detection data, instead of continuously supplying power in real time or supplying power in a fixed power supply period, and the detection frequency can be adjusted according to the data state in time under the condition that the detection duration of the object to be detected by the detection device is prolonged, so that the detection of the abnormal state of the object to be detected is avoided being missed.
In addition, in order to save the electric quantity of the electric storage power supply, the embodiment of the application also sets the power supply duration, that is, the detection device is in the power-on state in the preset time period. The preset time period may be a preset specific value, or may be periodically adjusted according to the electric quantity of the power storage power supply, the change speed of the detected data, and the like.
In summary, in the embodiment of the present application, when the detecting device is powered by the power storage power supply, a power supply period is set for the power storage power supply, and the power storage power supply is controlled according to the power supply period, so that the detecting device is intermittently in a power-on state to obtain the detection data of the object to be detected, and the state monitoring of the object to be detected is realized by non-real-time power supply, so that the detection duration of the object to be detected can be prolonged as long as possible under the limited electric quantity.
And the power supply period is obtained by adjusting the time length of the reference power supply period according to the last time of controlling the power switch according to the change speed of the detection data reflecting the state change trend of the object to be detected, so that the power supply period can be dynamically adjusted according to the change state of the detection data of the object to be detected, and the situation that the power is supplied to the user frequently under the condition that the state of the detection data is stable, and electric quantity waste is caused is avoided. Based on the above situation, the embodiment of the application achieves the purpose that the detection duration of the object to be detected by the detection device is prolonged under the condition that the electric storage power supply is limited.
Further, a power supply control method is described based on the following embodiment.
The above describes the manner of inversely adjusting the reference power supply period based on the positive and negative directions and the numerical values of the change speed of the detection data, it can be understood that the predicted qualified data limit value of the detection data may have an upper limit value and a lower limit value, and if the reference power supply period is reversely adjusted according to the change direction of the change speed of the data only, the time period corresponding to the power supply period may be prolonged when the change speed is negative, and instead, the abnormal data of the detection data of the object to be detected floating at the lower limit value may be missed, so that the abnormal state of the object to be detected cannot be detected.
Based on this, in the embodiment of the present application, the manner of reverse adjustment of the reference power supply period based on the change speed of the detection data may further include:
after the power switch is controlled last time to enable the detection device to be in an electrified state, historical detection data of an object to be detected and detection data of the object to be detected, which are acquired by the detection module at the current moment, are acquired, wherein the historical detection data are detection data at all moments before the current moment; analyzing based on the detection data and the historical detection data, determining the data change quantity of the detection data of the object to be detected in a preset time interval, and recording the data change quantity as the change speed of the detection data; determining the change duration of the detected data to the preset qualified data limit value based on the change speed; when the change duration is not greater than a preset emergency duration, shortening the duration corresponding to the reference power supply period based on a preset adjustment amplitude to obtain the power supply period; and when the change time length is longer than the preset emergency time length, prolonging the time length corresponding to the reference power supply period based on the preset adjustment amplitude to obtain the power supply period.
In the embodiment of the application, the change mode of the change speed of the detection data is not particularly considered, but the change time length required for the change of the detection data to the preset qualified data limit value is calculated according to the change speed of the detection data, so that the relation between the current detection data and the preset qualified data limit value can be determined. When the change duration is smaller than or equal to the preset emergency duration, the current detection data is proved to be changed to the preset qualified data limit value in a very short time, and the object to be detected is in an abnormal state, so that the duration of the reference power supply period is required to be shortened, the detection frequency is improved, and the abnormal state of the object to be detected is grabbed to give an alarm. If the change duration is not less than the preset emergency duration, the fact that the object to be detected cannot generate abnormal data in a short time is proved, no alarm is needed, the duration corresponding to the reference power supply period can be properly prolonged, and the power supply period is obtained.
It can be appreciated that the change speed of the detected data is proportional to the change duration, and the change duration is inversely proportional to the power supply period, so that in the embodiment of the present application, the adjustment of the reference power supply period is also reversely adjusted according to the change speed, which does not conflict with the preset adjustment rule described above.
Optionally, in the embodiment of the present application, a change trend of the detection data is first analyzed based on the detection data and the historical detection data, so as to obtain a change speed, thereby being convenient for determining whether a preset qualified data limit value for calculating a change duration is an upper limit value or a lower limit value, if the change trend is an increase trend, the preset qualified data limit value may be an upper limit value, otherwise, if the change trend is a decrease trend, the preset qualified data limit value may be a lower limit value.
However, the embodiment of the application may also calculate the time between the upper limit value and the lower limit value of the detected data at the same time, and jointly refer to the adjustment of the reference power supply period. Therefore, other ways of calculating the change speed may be selected in the embodiments of the present application, which are not limited herein, and the calculation ways may be selected according to the actual application, which are not illustrated herein.
It can be understood that the controller can receive real-time detection data of the object to be detected, which is collected by the detection module, under the power-on state, and the electric quantity of the electric storage power supply is reasonably distributed, so that the residual electric quantity of the electric storage power supply needs to be obtained at the same time, and if an abnormal condition is detected, an alarm is needed to be given out in addition to the adjustment of the power supply period so as to remind a worker to timely process the electric quantity, and the actual effect of the detection device is exerted.
Optionally, in an embodiment of the present application, the steps required to be performed by the controller may further include: acquiring the residual electric quantity of the electric power storage power supply; when the detection data of the object to be detected is not in the range value of the preset detection qualified data or the residual electric quantity is smaller than the preset electric quantity threshold value, alarm information representing abnormal detection is sent to the alarm module; when the alarm time length of the alarm module responding to the alarm information meets the preset alarm time length, the power switch is controlled to enable the detection device to be in a power-off state.
When the detection data does not accord with the numerical value interval specified by the preset detection qualified data range value, an alarm is required, and also if the residual electric quantity of the power storage power supply is insufficient to support the power-on detection of the next power supply period, the alarm is required.
The preset electric quantity threshold can be set according to the electric quantity which is averagely consumed after the detection device is electrified every time, and the preset electric quantity threshold can at least meet the requirement that the detection device is electrified at least once again, so that the situation that a worker fails to receive alarm information in time and misses an abnormal state prompt is avoided.
In addition, considering the limited electric quantity of the electric storage power supply, the embodiment of the application presets an alarm time length for each alarm, and the preset alarm time length can be a specific value and can be adaptively adjusted according to the emergency degree of the current condition. For example, detecting data abnormality, and in order to ensure safe operation of an object to be detected, a preset alarm time length needs to be prolonged; if the residual electric quantity is insufficient, the alarm time is shortened, the electric quantity is saved, and the like.
Based on the above embodiments, it can be seen that, in the case of limited power storage, the power supply control method mainly adaptively adjusts the power supply mode according to the data change condition of the detection data of the object to be detected, and timely detects the data state of the object to be detected while saving the electric quantity as much as possible, and prolongs the detection duration of the object to be detected when the power storage battery is in the limited electric quantity. Referring to fig. 2, an application example diagram of an application power control method provided in an embodiment of the present application is described to illustrate a practical application manner of the power control method.
Fig. 2 shows a detection apparatus for detecting air tightness of an absorption lithium bromide unit (hereinafter may be simply referred to as a unit), wherein the air tightness detection apparatus includes: mains power, power storage, solar power, charging power, power switch S1, controller/control board, pressure sensor, temperature sensor, wireless device and wireless communication switch S2.
The pressure sensor and the temperature sensor are equivalent to the detection modules described above and are respectively used for collecting real-time pressure values and real-time temperature values inside the unit. The microprocessor in the control panel can convert the acquired real-time pressure value into a pressure value corresponding to a preset temperature value according to the real-time temperature value, and based on the comparison of the pressure value and a preset pressure qualification limit value, whether the air tightness of the current unit is abnormal or not is determined.
As can be seen from fig. 2, the air tightness detection device has three power supplies for providing 220V voltage source, but when the mains power supply and the solar power supply fail and cannot supply power, S1 needs to be adjusted to the node corresponding to the power storage power supply, and the power storage power supply is used to complete normal power on of the air tightness detection device.
In the case of being supplied with power only by the electric storage power source, the control board performs the power source control method described above, realizing intermittent power supply of the electric storage power source to the airtight device. The control core of the control panel has automatic dormancy and timing awakening functions, and in the initial power supply stage of the power storage power supply, if the pressure value is maintained under a stable condition, the residual electric quantity of the battery is sufficient, the timing awakening can be performed by adopting a longer power supply period, and after each awakening, the control switch S1 enables the air tightness detection device to be in a power-on state, so that the collection of the unit data by the detection module and the collection and storage of the electric quantity of the power storage power supply are completed.
Further, the newly acquired pressure value is compared with the pressure value stored in the previous times, and the airtightness change trend of the unit is predicted through the calculation of the time interval and the data change quantity. Judging whether an alarm is necessary, if not, carrying out a dormant state, namely controlling S1 to enable the air tightness detection device to be in a power-off state, and waiting for the next awakening according to the power supply period. If the alarm is needed, an alarm signal is sent to the wireless device, so that the remote reminding of the user side is realized.
Meanwhile, the air tightness change trend of the unit is predicted according to the time interval and the calculation of the data change quantity, wherein the change trend can be represented by detecting the change speed of the data. If the change speed is high, the time length of the power supply period is shortened, the acquisition frequency of the detection module to the unit data is improved, the alarm time length can be shortened, and the effect of reminding a user side to finish the pressure maintaining of the unit as soon as possible is achieved. And if the change speed is slower, the duration of the power supply period is prolonged, the collection frequency of the detection module to the unit data is shortened, and the frequent collection of the same data is avoided, so that the electric quantity of the electric storage power supply is wasted.
The air tightness detection device also provides a charging power supply for the electric storage power supply, and when the electric storage power supply is not needed to supply power, the charging power supply charges the electric storage power supply through the branch of the mains supply, so that the utilization rate of the electric storage power supply is improved.
