Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system configurations, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the following description will be made with reference to the accompanying drawings by way of specific embodiments.
In embodiments of the present application, the fault indicator may include a solar panel and a backup power source, both for powering the fault indicator, the solar panel also for charging the backup power source.
Specifically, the fault indicator further comprises a main power supply, the main power supply is a voltage conversion circuit, and the main power supply is respectively connected with the solar panel and the backup power supply. The solar panel is used for supplying power to each device in the fault indicator through the main power supply, and the backup power supply is used for supplying power to each device in the fault indicator through the main power supply.
Alternatively, the backup power source may be an energy storage device such as a storage battery. The solar panel can supply power for the fault indicator in the daytime, so that the fault indicator can work normally, and meanwhile, the solar panel can charge a backup power supply, so that the electric quantity of the backup power supply can be ensured. At night, when the solar panel cannot work, the backup power supply supplies power for the fault indicator, so that the normal work of the fault indicator is ensured.
In embodiments of the present application, there are a variety of operating states for the backup power source, including a charged state, a discharged state, a stopped charged state, and a stopped discharged state.
Specifically, the charging state is a state in which the solar panel charges to the backup power supply, the discharging state is a state in which the backup power supply supplies power to the fault indicator, the charging stopping state is a state in which the solar panel stops charging to the backup power supply, and the discharging stopping state is a state in which the backup power supply stops supplying power to the fault indicator.
The charging MOS switch tube is arranged between the backup power supply and the solar panel, and when the charging MOS switch tube is conducted, the solar panel charges the backup power supply, and the backup power supply is in a charging state. When the charging MOS switch tube is turned off, the solar panel stops charging the backup power supply, and the backup power supply is in a state of stopping charging.
A discharging MOS switch tube is arranged between the backup power supply and the main power supply of the fault indicator, and when the discharging MOS switch tube is conducted, the backup battery supplies power to the main power supply, and the backup power supply is in a discharging state. When the discharging MOS switch tube is turned off, the backup battery stops supplying power to the main power supply, and the backup power supply is in a discharging stopping state.
In the practical application process, after the fault indicator is installed on the distribution line, the backup power supply is generally in a discharging state so as to ensure that the power supply can be switched seamlessly at night and ensure that the fault indicator works normally.
In the case of distribution line repair, it is sometimes necessary to disassemble the fault indicator and reinstall it after waiting for repair. Because the construction team knows the fault indicators of each manufacturer to different degrees, manual power failure of each detached fault indicator cannot be achieved, namely the backup power supply is cut off to discharge. After the fault indicator which is not powered off is stored in the warehouse, the backup power supply always supplies power for the fault indicator, and the fault indicator is always in an operating state.
The solar panel cannot work normally and cannot charge the backup power supply, the backup power supply may enter a self-discharge state due to low-voltage protection after the electric quantity is exhausted, permanent damage to the backup power supply may be caused after a period of time, and the fault indicator may be prevented from being reinstalled and working at night, so that the working reliability of the fault indicator is affected.
In order to solve the above problems, the embodiments of the present application provide a control method applied to the above fault indicator, and by determining the installation state of the fault indicator, the working state of the backup power supply is controlled, so as to prevent the backup power supply from being overdischarged, and ensure the working reliability of the fault indicator. The following is a detailed description.
Referring to fig. 1, a flowchart of implementation of a control method provided in an embodiment of the present application is shown. As shown in fig. 1, a control method applied to the above-mentioned fault indicator including a solar panel and a backup power source may include S101 and S102.
S101, detecting whether the fault indicator is in an installation state.
Alternatively, the execution body of the embodiment of the present application may be a micro control unit (Microcontroller Unit, MCU) or other controller, and the MCU may be provided in the fault indicator.
In the embodiment of the application, the MCU can detect the installation state of the fault indicator, detect the working state of the backup power supply and control the backup power supply to switch the working state.
Alternatively, the MCU may determine whether the fault indicator is in the installed state by detecting whether a connection between the fault indicator and the distribution line. Or the MCU acquires the height of the fault indicator by detecting the gravity of the fault indicator, so as to judge whether the fault indicator is in an installation state.
Specifically, the fault indicator further comprises a gravity acquisition unit, wherein the gravity acquisition unit is used for measuring the installation position of the fault indicator. The gravity acquisition unit can be a gravity sensor, the gravity sensor can acquire the installation position of the fault indicator, and the gravity acquisition unit can be connected with the MCU.
And acquiring the installation position of the fault indicator measured by the gravity acquisition unit. If the installation position is at the designated position, the fault indicator is determined to be in the installed state. If the installation position is not at the designated position, the fault indicator is judged not to be in the installation state.
After the MCU acquires the installation position of the fault indicator acquired by the gravity acquisition unit, whether the fault indicator is in an installation state can be judged according to whether the current installation position is in a designated position or not. The designated location is a predetermined normal installation location of the fault indicator.
S102, if the fault indicator is not in the installation state, acquiring a first voltage value, and controlling the backup power supply to be in a discharge stopping state when the first voltage value is not greater than a first preset voltage value, wherein the first voltage value is the voltage value of the solar panel.
And when the MCU judges that the fault indicator is in the uninstalled state, the MCU acquires a first voltage value of the solar panel. And when the first voltage value is smaller than a first preset voltage value, namely the first voltage value of the solar panel is too low, the backup power supply is controlled to be in a discharge stopping state, so that the backup power supply stops supplying power to the fault indicator.
When the fault indicator is in an uninstalled state, the fault indicator is not required to work, and when the first voltage value of the solar panel is too low, the fault indicator is possibly placed in a storehouse or a dark place, and the standby power supply needs to be controlled to stop discharging in order to ensure the electric quantity of the standby power supply.
Specifically, when the fault indicator is not in the installation state, if the backup power supply is in the discharge state currently, when the first voltage value is obtained and is smaller than the first preset voltage value, the backup power supply is controlled to be switched from the discharge state to the stop discharge state.
When the fault indicator is in an uninstalled state, if the backup power supply is in a discharge state currently, when the first voltage value is obtained and is smaller than a first preset voltage value, the backup power supply is controlled to keep in a discharge stopping state.
Alternatively, the first preset voltage value may be a value near the lowest voltage value of the solar panel, and the absolute value of the difference between the first preset voltage value and the lowest voltage value of the solar panel is smaller than the first preset value.
For example, the minimum voltage value of the solar panel is 0.5V, the first preset value is 2V, and the first preset voltage value may be any value between (0,2.5V), for example, the first preset voltage value may be 1V, which may be specifically set according to practical situations.
According to the embodiment of the application, whether the fault indicator is in the installation state or not is detected, when the fault indicator is not installed and the voltage value of the solar panel is too low, at the moment, the fault indicator can be detached and placed in a storehouse, the backup power supply can be controlled to be in a stop discharge state, so that the backup power supply is prevented from being excessively discharged under the condition of no charging power supply, and the working reliability of the fault indicator can be improved.
In some embodiments of the present application, "when the first voltage value is not greater than the first preset voltage value," controlling the backup power source to be in the discharge stopping state "in S102 may include:
And when the duration that the first voltage value is not more than the first preset voltage value exceeds the first preset duration, controlling the backup power supply to be in a discharge stopping state, wherein the absolute value of the difference value between the first preset voltage value and the lowest voltage value of the solar panel is smaller than the first preset value.
When the MCU detects that the fault indicator is not in the installation state, a first voltage value is obtained, and when the duration that the first voltage value is not longer than a first preset voltage value exceeds a first preset duration, the standby power supply is controlled to be in a discharge stopping state, so that the standby power supply is prevented from being discharged for a long time to enter a self-discharge state, and the service life of the standby power supply is ensured.
The first voltage value is not larger than a first preset voltage value, the current solar panel voltage is indicated to be too low, the duration time exceeds the first time, the solar panel is indicated to be unlit for a long time, and the fault indicator can be considered to be placed in a warehouse.
Optionally, the first preset duration may be a preset maximum duration in which the solar panel is not illuminated. Or the first preset duration is the preset maximum duration of the under-voltage state of the solar panel. Specifically, the selection can be performed according to actual conditions.
For example, when the MCU detects that the fault indicator is in an uninstalled state and the first voltage value of the solar panel lasts for 24 hours or less than 1V, the MCU judges that the fault indicator is placed in a warehouse for a long time, and at the moment, the standby power supply is controlled to be in a discharge stopping state so as to power off the fault indicator.
According to the embodiment of the application, when the voltage of the solar panel is too low for a long time, the backup power supply is controlled to be in a stop discharge state, so that the backup power supply is guaranteed to enter a self discharge state under the condition of sufficient electric quantity, the backup power supply is prevented from being over-discharged, and the service life and the working reliability of the fault indicator are guaranteed.
In some embodiments of the present application, after detecting whether the fault indicator is in the installed state, the method further comprises:
if the fault indicator is not in the installed state, a first voltage value is obtained.
When the duration that the first voltage value is not longer than the first preset duration, a second voltage value is obtained, and when the first voltage value is greater than the second voltage value, the backup power supply is controlled to be in a charging state, wherein the second voltage value is the voltage value of the backup power supply.
When the MCU detects that the fault indicator is not in the installation state, a first voltage value is obtained, and when the duration of the first voltage value which is not longer than the first preset voltage value is not longer than the first preset duration, the fault indicator is indicated to be possibly placed in open air, and the solar panel can perform energy conversion. At this time, the MCU can acquire a second voltage value of the backup power supply, and when the first voltage value is larger than the second voltage value, the solar panel can charge the backup power supply, and in order to ensure the electric quantity of the backup power supply, the MCU can control the backup power supply to be in a charging state.
Illustratively, when the MCU detects that the fault indicator is in an uninstalled state and the first voltage value of the solar panel does not satisfy the duration of 24 hours or more of 1V, the MCU judges that the detached fault indicator is placed in the open air. At this time, if the first voltage value of the solar panel is greater than the second voltage value of the backup power supply, the backup power supply is controlled to be in a charging state, so that the solar panel charges the backup power supply, and the electric quantity of the backup power supply is ensured.
According to the embodiment of the application, when the fault indicator is detached and placed in the open air, the solar panel is in a charging state when the voltage is high, the electric quantity of the backup power supply is guaranteed, the probability that the backup power supply is damaged due to the fact that the electric quantity is insufficient and self-discharging is reduced, and the service life of the fault indicator is guaranteed.
In some embodiments of the present application, after obtaining the second voltage value, the method further comprises:
and when the second voltage value is smaller than a second preset voltage value, controlling the backup power supply to be in a discharge stopping state, wherein the difference value between the second preset voltage value and the rated voltage value of the backup power supply is larger than the second preset value.
When the MCU detects that the fault indicator is not in the installation state, a first voltage value is acquired, and when the duration of the first voltage value which is not longer than the first preset voltage value does not exceed the first preset duration, the fault indicator is indicated to be possibly placed in the open air, and the solar panel can perform energy conversion. At this time, the MCU may acquire a second voltage value of the backup power supply, and when the second voltage value is smaller than a second preset voltage value, it indicates that the power level of the backup power supply is too low, and the MCU may control the backup power supply to be in a discharge stopping state, so as to ensure the power level of the backup power supply.
Specifically, when the duration that the first voltage value is not longer than the first preset duration, a second voltage value is obtained, and when the first voltage value is greater than the second voltage value and the second voltage value is smaller than the second preset voltage value, the backup power supply is controlled to start charging and stop discharging.
The second preset voltage value may be a voltage value less than a certain difference value of the rated voltage value of the backup power supply. The rated voltage value of the backup power supply is 15V, the second preset value is 2V, and the second preset voltage value can be any voltage value smaller than 13V, for example, can be 12.8V.
For example, the MCU detects that the fault indicator is in an uninstalled state, and the first voltage value of the solar panel does not satisfy 24 hours and is less than 1V, and if the collected first voltage value of the solar panel is greater than the second voltage value of the backup battery and the second voltage value of the backup battery is less than 12.8V, the MCU controls the backup power supply to start charging, and controls the backup power supply to stop discharging.
According to the embodiment of the application, the fault indicator is placed in the open air, the solar panel is high in voltage, and when the voltage of the backup power supply is low, the backup power supply is controlled to stop discharging and start charging, so that the electric quantity of the backup power supply can be improved, and the working reliability of the backup power supply is guaranteed. To a certain extent, the working time of the fault indicator at night after charging and mounting can be prolonged, and the working efficiency of the fault indicator is improved.
In some embodiments of the present application, after determining whether the fault indicator is in the installed state, the method further comprises:
if the fault indicator is in the installation state and the backup power supply is in the charging stop state, acquiring a second voltage value, and controlling the backup power supply to be in the charging state when the first voltage value is larger than the second voltage value and the second voltage value is smaller than a third preset voltage value, wherein the second voltage value is the voltage value of the backup power supply.
After judging whether the fault indicator is in the installation state or not, if the fault indicator is in the installation state and the backup power supply is in the charging stop state, the MCU acquires a second voltage value of the backup power supply, and when the first voltage value of the solar panel is larger than the second voltage value of the backup power supply and the second voltage value of the backup power supply is smaller than a third preset voltage value, the MCU controls the backup power supply to be switched from the charging stop state to the charging state.
The fault indicator typically will be shipped with the backup power supply of the fault indicator in a stopped state of charge. Because constructors are unfamiliar with fault indicators of various factories, the fault indicators may not be installed in a powered-on manner, and the fault indicator solar panel cannot charge a backup power supply.
For the above situation, when the fault indicator is installed and not powered on, the MCU will automatically power up and control the backup power source to be in a charging state when detecting that the first voltage value of the solar panel is higher than the second voltage value of the backup power source. The fault indicator can be automatically electrified after being installed without manual operation, so that the installation time is reduced, the automation degree of the fault indicator is improved, the reliable operation of the fault indicator is ensured, and the reliability of the fault detection of the power distribution network line is improved.
In some embodiments of the present application, the fault indicator further comprises a gravity acquisition unit for measuring the mounting position of the fault indicator.
The "detecting whether the fault indicator is in the mounted state" of S101 may include:
and acquiring the installation position of the fault indicator measured by the gravity acquisition unit.
If the installation position is at the designated position, the fault indicator is determined to be in the installed state.
If the installation position is not at the designated position, the fault indicator is judged not to be in the installation state.
Alternatively, the gravity acquisition unit may comprise a gravity sensor, or a gravity acquisition circuit consisting of a gravity sensor. The designated location may be a pre-set mounting location for the fault indicator.
The gravity sensor can collect the installation position of the fault indicator and send the installation position to the MCU. The MCU compares the installation position sent by the gravity sensor with the designated position, so as to judge whether the fault indicator is installed.
Specifically, the MCU can judge according to the gravity signals collected by the gravity sensor at different positions.
When the fault indicator is not at the designated position, the gravity signal currently collected by the gravity sensor is not equal to the gravity signal at the designated position, and the fault indicator can be judged to be in an uninstalled state.
When the fault indicator is at the designated position, the gravity signal currently collected by the gravity sensor is equal to the gravity signal at the designated position, and the fault indicator can be judged to be in the installation state.
According to the embodiment of the application, the gravity acquisition unit is arranged, so that the automatic detection of the installation state of the fault indicator can be realized, manual judgment is not needed, and the degree of automation of the fault indicator can be improved.
When the fault indicator is not installed on the site, the backup power supply is actively turned off, so that the backup power supply enters a self-discharge state under the condition of sufficient electricity, the self-discharge time of the backup power supply can be maximally improved, and the permanent damage probability of the backup power supply is reduced.
It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic of each process, and should not limit the implementation process of the embodiment of the present application in any way.
The following are device embodiments of the present application, for details not described in detail therein, reference may be made to the corresponding method embodiments described above.
