Description

Technical Field

[0001] The invention belongs to the technical field of battery power display, and in particular to a battery power status display system and method for an electronic blocking device. Background Art

[0002] The electronic barrier device is an important safety prevention tool. It uses advanced sensing technology and intelligent analysis algorithms to achieve real-time monitoring and protection of specific areas. The main application scenarios include nature reserves, military bases or important facilities. The main components include sensor modules, control units, alarm systems and power modules. Especially in the wild environment, due to the lack of stable power supply, the electronic barrier devices in the wild environment are generally powered by solar panels, and solar power supply is unstable. Therefore, it is particularly important to monitor and display the power status of electronic barrier devices used in the wild environment.

[0003] In the prior art, a battery power detection method is generally used to convert the actual remaining power of a battery pack into the remaining power to be displayed on a display screen for display. Based on the above, when the remaining power to be displayed of the battery pack is reduced to a certain level, an alarm or reminder will be triggered, thereby reminding the staff to replenish it in time to prevent the electronic barrier device from being closed and causing the protected specific area to be invaded, causing a safety hazard; the set horizontal line generally takes into account the speed at which the battery pack consumes power. In the process of the remaining power to be displayed of the battery pack changing from the horizontal line to being completely exhausted, a certain amount of time is generally left for the staff to replenish power, and this time can be predicted.

[0004] However, in actual application, considering that the performance of the battery pack may decay with the service time of the battery pack, that is, the time for the remaining power to be displayed of the battery pack in the initial service stage, that is, the time for the remaining power to be displayed of the battery pack in the stable period to change from the horizontal line to completely exhausted is longer than the time for the remaining power to be displayed of the battery pack in the decay period to change from the horizontal line to completely exhausted. Therefore, if the service time of the battery pack is too long, there is a certain risk in converting the actual remaining power of the battery pack into the remaining power to be displayed on the display screen, which may cause the battery pack to be exhausted unexpectedly quickly, and then cause the electronic barrier device to be closed, providing conditions for the invasion of specific areas.

[0005] To this end, the present invention provides a battery power status display system and method for an electronic blocking device. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0069] The present invention will be further described below in conjunction with the accompanying drawings.

[0070] Figure 1 It is a flow chart of the present invention. DETAILED DESCRIPTION

[0071] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0072] like Figure 1 As shown, a battery power status display system of an electronic blocking device according to an embodiment of the present invention includes:

[0073] The power monitoring module is used to detect the power status of the battery pack and obtain the actual value of the remaining power of the battery pack;

[0074] A data processing module, based on the actual value of the remaining power of the battery pack, processes to obtain a reference value Q, and outputs a first detection result; the reference value Q is smaller than the actual value of the remaining power of the battery pack;

[0075] The method for determining the reference value Q of the remaining power of the battery pack is as follows:

[0076]

[0077] in, is the insurance factor, Q γ is the default value, Q s The actual remaining capacity of the battery pack;

[0078] Based on the above, in order to cope with the problem that the battery pack power decays quickly during the decay period, even if the system generates a reminder signal, the staff cannot take timely countermeasures, which leads to the closure of the electronic blocking device. In one embodiment of the present invention, a safety factor can be set to make the reference value Q of the remaining power of the battery pack smaller than the actual remaining power of the battery pack, so as to cope with the problem that the power of the battery pack decays too quickly. For example, if the actual remaining power of the battery pack is 10kWh, The calculated reference value Q is 5kWh, which is exactly equal to the preset value. At this time, the decision module will output the first control instruction, thereby generating an alarm signal. When the actual remaining power is 100kWh, the reference value Q displayed by the display module is 100, that is, as the power of the battery pack is consumed, the reference value Q processed by the data processing module gradually becomes smaller than the actual remaining power of the battery pack.

[0079] Among them, the actual remaining power of the battery pack is input s Satisfy Q s ≥2Q γ .

[0080] The display module is used to adjust the display content according to the reference value Q of the remaining power of the battery pack.

[0081] A decision module is used to receive the first detection result and compare it with the preset value Q γ For comparison:

[0082] If Q≤Q γ , then output a first control instruction; the decision module also includes an analysis unit, the analysis unit is used to evaluate the aging of the battery pack according to the battery pack life model, the method is:

[0083] Collecting the operating data of the battery pack based on the power monitoring module, i.e., the first detection result;

[0084] Based on the first test result and in combination with the battery life model, the battery aging condition is analyzed, including the stable period, the decay period, and the scrap period;

[0085] When the battery pack is evaluated to be in a stable period, the decreasing speed of the reference value Q satisfies the decreasing speed equal to the actual remaining power of the battery pack;

[0086] When the battery pack is evaluated to be in a decay period, the decreasing speed of the reference value Q satisfies the decreasing speed greater than the actual remaining power of the battery pack;

[0087] When the battery pack is evaluated to be scrapped, the decision module outputs a sixth control instruction, and the early warning module is further used to receive the sixth control instruction and output a first alarm signal;

[0088] An early warning module, used for receiving a first control instruction and outputting an alert signal;

[0089] The battery life model is pre-built based on battery type, specifications and usage parameters.

[0090] In actual application, it is taken into account that the performance of the battery pack may decay with the service time of the battery pack, that is, the time for the remaining power to be displayed of the battery pack in the initial service stage, that is, the stable period, to change from the horizontal line to completely exhausted is longer than the time for the remaining power to be displayed of the battery pack in the decay period to change from the horizontal line to completely exhausted. Therefore, if the battery pack is in service for too long, there is a certain risk in converting the actual remaining power of the battery pack into the remaining power to be displayed on the display screen, which may cause the battery pack to be exhausted unexpectedly quickly, and then cause the electronic barrier device to be closed, providing conditions for invasion of specific areas.

[0091] Based on the above, in order to cope with the problem of unpredictable rapid power exhaustion of batteries in the decay period, in one embodiment of the present invention, according to the actual remaining power of the battery pack detected by the power monitoring module, a first detection result is obtained through processing, that is, a reference value Q of the remaining power to be displayed of the battery pack; by setting the remaining power to be displayed smaller than the actual remaining power of the battery pack, an early alarm can be given when the decision module compares the reference value Q with the preset value, that is, a reminder signal is sent to the staff through the control module, thereby reserving more time for the staff to carry out emergency processing, avoiding the power module of the electronic barrier device from being shut down due to power exhaustion, and providing conditions for the invasion of a specific area;

[0092] The preset value is artificially set, for example, 5kWh, and the capacity of the battery pack is 100kWh. After the electronic barrier device is used for a period of time, the actual remaining capacity of the battery pack drops to 10kWh. At this time, since the preset reference value Q is 5kWh, the reference value Q is equal to the preset value. The decision module outputs a first control instruction. The control module outputs a reminder signal based on the first control instruction. When the staff receives the reminder signal, they can take emergency measures in time. For example, in long-term rainy weather, when the output power of the solar panel is low, the backup battery can be started to supply power to ensure the stable operation of the electronic barrier device.

[0093] As the service time of the battery pack increases, the battery pack will go from a stable period to a decay period and finally to a scrap period. According to the different periods of the battery pack, the battery pack power status display mode can be changed accordingly. For example, in one embodiment of the present invention, the aging of the battery pack is evaluated through the battery pack life model and the battery pack operation data. When the battery pack is in a stable period, the remaining power to be displayed of the battery pack, that is, the decreasing speed of the reference value Q satisfies the decreasing speed of the actual remaining power of the battery pack, indicating that the setting of the reference value Q at this time can meet the effect of preventing the remaining power of the battery pack from being quickly exhausted. However, when the battery pack is in a decay period, in addition to setting a reference value Q greater than the actual remaining power of the battery pack, the reference value Q displayed in the display module can also be adjusted in speed, that is, the decreasing speed of the reference value Q is set to be greater than the decreasing speed of the actual remaining power of the battery pack. Assuming that there are staff patrols in the electronic barrier device area in the field environment, it can be predicted in advance that the battery pack is about to run out of power, so as to take countermeasures in advance. In addition, when the battery pack is in a scrap period, a first alarm signal is output to prompt the staff to replace the battery pack in time.

[0094] Preferably, it also includes:

[0095] A power monitoring module, used to detect the output voltage and output current of the solar panel, obtain the output power of the solar panel, and output a second detection result;

[0096] The display module is further used to adjust the display content according to the second detection result, and the display content also includes the output power, output current and voltage of the solar panel;

[0097] The decision module is also used to receive the second detection result, and output the second control instruction and the third control instruction in combination with the analysis of the first detection result;

[0098] The control module is used to receive the second control instruction to control the backup power supply to discharge and receive the third control instruction to control the backup power supply to stop discharging.

[0099] As mentioned above, in the wild environment, continuous rainy days may affect the output power of the solar panel, which in turn causes the battery pack to continue to be unable to be replenished. In addition, due to the need to maintain the normal operation of the electronic barrier device, the remaining power of the battery pack will sooner or later be exhausted. In addition to the fact that rainy days will affect the output power of the solar panel, if there is a fault in the solar panel, it will also cause the output power of the solar panel to be abnormal. In order to avoid the situation where the battery pack is continuously unable to be replenished due to the low output power of the solar panel, in one embodiment of the present invention, a power detection module is also provided in the system, and the output power of the solar panel is obtained through the power detection module, and a second detection result is output. The display module can also display the second detection result. In addition, after receiving the first detection result and the second detection result, the decision module analyzes whether it is necessary to enable the backup power supply according to the first detection result and the second detection result to prevent the electronic barrier device from being shut down due to the exhaustion of the battery pack. When the decision module outputs the second control instruction, the control module controls the backup power supply to discharge, and when the decision module outputs the third control instruction, the control module controls the backup power supply to stop discharging.

[0100] Preferably, the method by which the decision module outputs the second control instruction is:

[0101] When the first situation occurs, the second control instruction is not output; the first situation satisfies that the second detection result is lower than the threshold value, and the first detection result is not lower than the preset value;

[0102] When a second situation occurs, a second control instruction is output; the second situation satisfies that the second detection result is lower than a threshold value, and the first detection result is lower than a preset value;

[0103] When a third situation occurs, a second control instruction is output; the third situation satisfies that the second detection result is not lower than a threshold value, and the first detection result is lower than a preset value;

[0104] When the fourth situation occurs, the second control instruction is not output; the fourth situation satisfies that the second detection result is not lower than the threshold value, and the first detection result is not lower than the preset value Q γ , output the third control instruction.

[0105] Based on the above, the relationship between the output power of the solar panel and the remaining power of the battery pack is analyzed according to the first detection result and the second detection result. Regardless of whether the second detection result is lower than the threshold, as long as the first detection result is lower than the preset value Q γ , the decision module will output a second control instruction to automatically switch to the backup power supply to prevent the electronic blocking device from shutting down when the battery pack is exhausted;

[0106] For example, the first scenario corresponds to the beginning of rainy weather, when the remaining power of the battery pack is relatively abundant; the second scenario corresponds to the situation that the solar panel continues to output low power during long-term rainy weather, and the remaining power of the battery pack gradually decreases to close to the preset value; the third scenario corresponds to the end of long-term rainy weather, when the output power of the solar panel increases, but the remaining power of the battery pack is still less than or equal to the preset value, wherein, when the third scenario occurs, the discharge operation of the backup power supply controlled by the second control instruction is maintained; the fourth scenario corresponds to the end of long-term rainy weather, and the remaining power of the battery pack is greater than the preset value, indicating that the battery pack is in the charging process, and the third control instruction is output at this time, and the backup power supply is controlled to stop discharging by the third control instruction; it is worth noting that the first scenario, the second scenario, the third scenario, and the fourth scenario generally appear in sequence, if the second detection result continues to be lower than the threshold value, it indicates that the solar panel may be faulty, for example, in clear weather, if the second detection result is still lower than the threshold value, it is confirmed that the solar panel is indeed faulty and needs to be maintained in time, otherwise the backup battery may also run out of power.

[0107] Preferably, it also includes:

[0108] The light intensity detection module is used to detect the ambient light intensity and output the light intensity value L;

[0109] The decision module is also used to receive the light intensity value L, and analyze whether the solar panel is abnormal according to the second detection result and the light intensity value L, and output a fourth control instruction when the solar panel is abnormal;

[0110] The early warning module is further used to receive a fourth control instruction and output a second alarm signal.

[0111] Based on the above, if the second detection result is continuously lower than the threshold, it indicates that the solar panel may be faulty. When there are few staff members working on the electronic barrier device in the outdoor environment, it is difficult to conduct on-site inspections of the operation of the solar panel. Therefore, in one embodiment of the present invention, in order to remotely confirm whether the solar panel is faulty, a light intensity detection module may be provided to detect the ambient light intensity and output a light intensity value L. Based on the light intensity value L and the second detection result, it is analyzed whether the solar panel is abnormal. If the solar panel is confirmed to be abnormal, a fourth control instruction is output, and the early warning module is used to alert the staff, i.e., a second alarm signal is output.

[0112] Preferably, the method for the decision module to analyze whether the solar panel is abnormal is:

[0113] Get the output power W of the solar panel and the light intensity value L;

[0114] According to the formula:

[0115] A=W / L

[0116] Where A represents the ratio of the solar panel output power W to the light intensity value L, that is, the photoelectric conversion ratio;

[0117] when The solar panel is abnormal;

[0118] when The solar panel is normal;

[0119] when The solar panel is abnormal;

[0120] in, represents the average photovoltaic conversion ratio interval calculated based on the historical output power and historical light intensity values ​​of the solar panel, and

[0121] The working principle of solar cells is to convert light energy into electrical energy, so the light intensity directly determines how much energy the solar cell can capture; under stronger light, the output power of the solar cell will be higher; this is because when the light intensity increases, the solar cell can capture more photons, thereby generating more electron-hole pairs, and then generating greater current and voltage; the output power W calculated based on the current and voltage and the light intensity value L should be satisfied near a certain value or range, so even if there is a difference in ambient light intensity, as long as the photoelectric conversion ratio is calculated, it can reflect whether the output power of the solar panel is affected by performance or life. In one embodiment of the present invention, by calculating the photoelectric conversion ratio A of the solar panel, according to the set average photoelectric conversion ratio interval When the photoelectric conversion ratio A falls into the average photoelectric conversion ratio interval This indicates that the solar panel is operating normally. or All indicate that the solar panels are operating abnormally. When , it means that the solar panel may have a short circuit or open circuit. , it means that the solar panel may be blocked.

[0122] Preferably, it also includes a management module, which is used to manage the priority of each function in the electronic blocking device according to the energy consumption of each function in the electronic blocking device; the priority is to pre-configure the priority of each function according to the needs and actual situation of the electronic blocking device;

[0123] When the decision module outputs the second control instruction, the management module outputs a closing signal based on the priority of each function in the electronic blocking device; the decision module is also used to receive the closing signal and output a fifth control instruction; the control module is also used to receive the fifth control instruction to complete the closing of each function in the electronic blocking device.

[0124] Among them, priority management is performed for each function in the electronic barrier device. Its main function is that when the output power of the solar panel is low and the remaining power of the battery pack is less than or equal to the preset value, the electronic barrier device mainly relies on the backup battery to maintain operation. However, the capacity of the backup battery is limited. Therefore, ensuring the operation of the main functions of the electronic barrier device can extend the service life of the backup power supply. Therefore, it is necessary to perform priority management on each function in the electronic barrier device. Based on the above, when the decision module outputs the second control instruction, the opening and closing control can be performed according to the pre-set priority of each function of the electronic barrier device. For example, if the main function of the electronic barrier device is intrusion warning, only this function will be retained after the backup power supply is started, and the remaining functions will be closed based on the shutdown signal and the fifth control instruction.

[0125] Preferably, a prediction module is also included, which is used to build a model based on historical weather conditions and solar panel output power, and predict the solar panel output power in the future, the method is:

[0126] Data collection, collecting data on historical weather conditions and solar panel output power;

[0127] Data preprocessing: preprocessing the collected data, including data cleaning, missing value filling, and outlier processing;

[0128] Feature selection, selecting feature variables that are closely related to the prediction of solar panel output power;

[0129] Model building, building prediction models based on machine learning algorithms;

[0130] Model training: Use historical data to train the model so that the model can learn the mapping relationship between input features and output power;

[0131] Prediction application, based on the weather conditions in the future, predicts the output power of solar panels and obtains the predicted power generation.

[0132] Due to the changeable weather conditions, when there is continuous rainy weather, since the capacity of the backup power supply and the battery pack is limited, it may not be possible to guarantee that the backup power supply can stably supply power to the electronic barrier device when the rainy weather ends. Based on the above scenario, in one embodiment of the present invention, by acquiring historical weather conditions and the corresponding solar energy output power, a model is constructed. Based on the construction of the model, in the application stage, the weather condition forecast can be directly input into the model to output the output power forecast result of the solar panel for a period of time in the future, so as to achieve the effect of early prediction and early formulation of emergency measures. The data may include meteorological parameters such as temperature, humidity, wind speed, and light intensity, as well as electrical performance parameters such as output voltage, current, and power of the solar panel. In the data processing stage, the data is standardized or normalized to eliminate the influence between different dimensions and improve the generalization ability of the model. Features include historical weather conditions such as temperature, humidity, Wind speed, light intensity, etc., and the electrical performance parameters of solar panels, such as output voltage, current, power, etc., can be reasonably selected to reduce the complexity of the model and improve the prediction accuracy. Machine learning algorithms can use linear regression, decision trees, neural networks, etc. or statistical methods, such as ARIMA model, exponential smoothing method, etc. In the process of model construction, model parameters need to be adjusted to obtain the best prediction effect; in the training process, cross-validation and other methods can be used to evaluate the performance of the model and prevent the occurrence of overfitting. Finally, based on the prediction results, emergency measures can be formulated, including but not limited to increasing the capacity of backup power supply, increasing the capacity of battery packs, and increasing the number of backup power supplies and battery packs. In addition, as time goes by and new data is continuously generated, the model needs to be updated and optimized regularly, which can be achieved by retraining the model or adjusting the model parameters to ensure that the model can adapt to new data and environmental changes.

[0133] Preferably, the decision module is also used to determine whether emergency measures need to be formulated based on the predicted power generation, in the following method:

[0134] When the sum of the power generation of the solar panel, the remaining capacity of the battery pack, and the backup power capacity in the future is greater than the power demand of the electronic barrier device, the sixth control instruction is not output;

[0135] When the sum of the power generation of the solar panel, the remaining capacity of the battery pack, and the backup power capacity in the future is less than or equal to the power demand of the electronic barrier device, the sixth control instruction is output;

[0136] The early warning module receives the sixth control instruction and outputs a third alarm signal;

[0137] The power requirement of the electronic blocking device is calculated based on the power consumption per unit time of the electronic blocking device, and the power consumption per unit time is monitored by a power monitoring module.

[0138] When the output power of the solar panel is predicted, the power generation of the solar panel can be calculated. The power generation of the solar panel, the remaining capacity of the battery pack, the capacity of the backup power supply and the power requirement of the electronic barrier device are compared to determine whether emergency measures need to be formulated in advance, that is, the sixth control instruction is output. When the early warning module receives the sixth control instruction, it outputs the third alarm signal. The staff can take emergency measures according to the third alarm signal, including but not limited to increasing the capacity of the backup power supply, increasing the capacity of the battery pack, and increasing the number of backup power supplies and battery packs; the above-mentioned period of time can be freely set, including but not limited to three days or one week;

[0139] The predicted power generation of the solar panels is calculated according to the formula:

[0140]

[0141] Among them, β is the loss parameter, P is the power generation of the solar panel, and W t is the output power at time t, ΔT t W t duration.

[0142] A method for displaying the battery power status of an electronic blocking device comprises the following steps:

[0143] S1: monitor the remaining capacity of the battery pack;

[0144] S2: Based on the actual value of the remaining power of the battery pack, a reference value Q is calculated;

[0145] S3: output the reference value Q to the display module for display;

[0146] S4: When the reference value Q is less than or equal to the preset value Q γ When the alarm is on, a reminder signal is output.

[0147] Working principle: Based on the above, in order to cope with the problem of unpredictable rapid power exhaustion of batteries in the decay period, in one embodiment of the present invention, according to the actual remaining power of the battery pack detected by the power monitoring module, a first detection result is obtained through processing, that is, a reference value Q of the remaining power to be displayed of the battery pack; by setting the remaining power to be displayed smaller than the actual remaining power of the battery pack, an early alarm can be given when the decision module compares the reference value Q with the preset value, that is, a reminder signal is sent to the staff through the control module, thereby reserving more time for the staff to carry out emergency processing, avoiding the power module of the electronic barrier device from being shut down due to power exhaustion, and providing conditions for the invasion of a specific area;

[0148] The preset value is artificially set, for example, 5kWh, and the capacity of the battery pack is 100kWh. After the electronic barrier device is used for a period of time, the actual remaining capacity of the battery pack drops to 10kWh. At this time, since the preset reference value Q is 5kWh, the reference value Q is equal to the preset value. The decision module outputs a first control instruction. The control module outputs a reminder signal based on the first control instruction. When the staff receives the reminder signal, they can take emergency measures in time. For example, in long-term rainy weather, when the output power of the solar panel is low, the backup battery can be started to supply power to ensure the stable operation of the electronic barrier device.

[0149] As the service time of the battery pack increases, the battery pack will go from a stable period to a decay period and finally to a scrap period. According to the different periods of the battery pack, the battery pack power status display mode can be changed accordingly. For example, in one embodiment of the present invention, the aging of the battery pack is evaluated through the battery pack life model and the battery pack operation data. When the battery pack is in a stable period, the remaining power to be displayed of the battery pack, that is, the decreasing speed of the reference value Q satisfies the decreasing speed of the actual remaining power of the battery pack, indicating that the setting of the reference value Q at this time can meet the effect of preventing the remaining power of the battery pack from being quickly exhausted. However, when the battery pack is in a decay period, in addition to setting a reference value Q greater than the actual remaining power of the battery pack, the reference value Q displayed in the display module can also be adjusted in speed, that is, the decreasing speed of the reference value Q is set to be greater than the decreasing speed of the actual remaining power of the battery pack. Assuming that there are staff patrols in the electronic barrier device area in the field environment, it can be predicted in advance that the battery pack is about to run out of power, so as to take countermeasures in advance. In addition, when the battery pack is in a scrap period, a first alarm signal is output to prompt the staff to replace the battery pack in time.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
