If the patrol abnormality value of the energy storage device exceeds the optimal energy storage device patrol abnormality threshold, the patrol evaluation symbol LP-1 is assigned to the corresponding energy storage device;

[0037] The number of energy storage devices assigned with the patrol evaluation symbol LP-1 during the detection period is obtained and the ratio thereof to the total number of energy storage devices that need to be supervised is calculated to obtain the patrol execution coefficient, and the ratio of the patrol abnormality value of the energy storage device to the patrol abnormality threshold of the corresponding optimal energy storage device is marked as the energy storage device patrol occupancy value, and the energy storage device patrol occupancy values ​​of all energy storage devices that need to be supervised are averaged to obtain the patrol performance coefficient;

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] Embodiment 1: Figure 1 As shown, the energy storage safety monitoring and early warning system applied to energy storage equipment proposed by the present invention includes an energy storage equipment power monitoring module, an energy storage equipment temperature monitoring module, a regional threat assessment module and a supervision and early warning terminal;

[0047] The power monitoring module of the energy storage device captures and analyzes the power anomaly of the energy storage device to determine whether to generate a power anomaly alarm signal, and sends it to the supervision and early warning end when the power anomaly alarm signal is generated. The supervision and early warning end issues a corresponding early warning when receiving the power anomaly alarm signal. It can monitor the voltage and current conditions of the energy storage device in real time and realize abnormal early warning, so as to remind the supervisor to make corresponding control and improvement measures in time, so as to ensure the energy storage safety of the energy storage device. The specific operation process of the power monitoring module of the energy storage device is as follows:

[0048] The operating voltage of the energy storage device is collected and compared with the preset normal voltage range. If the operating voltage is not within the preset operating voltage range, it indicates that there may be an undervoltage or overvoltage condition, which may cause damage to the equipment, and the voltage symbol ZP-1 is assigned;

[0049] The operating current of the energy storage device is collected, and the difference between the operating currents of two adjacent groups of time points is calculated to obtain the abnormal current fluctuation value. The abnormal current fluctuation value is numerically compared with the preset abnormal current fluctuation threshold. If the abnormal current fluctuation value exceeds the preset abnormal current fluctuation threshold, it indicates that the energy storage power supply has abnormal current fluctuation, and there is a high probability of short circuit, overload and other conditions, and the current symbol HP-1 is assigned;

[0050] When the voltage symbol ZP-1 or the current symbol HP-1 is assigned, it indicates that the energy storage power source has a power safety hazard and generates a power abnormality alarm signal.

[0051] The energy storage device temperature monitoring module performs risk analysis on the operating temperature of the energy storage device to determine whether to generate an abnormal temperature alarm signal, and sends the abnormal temperature alarm signal to the supervisory warning terminal when it is generated. The supervisory warning terminal issues a corresponding warning when it receives the abnormal temperature alarm signal. It can monitor the temperature of each position in the energy storage power supply in real time and accurately assess the temperature risk of the energy storage power supply, and promptly remind the supervisor to take reasonable improvement measures, significantly improving the energy storage safety of the energy storage power supply. The specific operation process of the energy storage device temperature monitoring module is as follows:

[0052] Several detection points are set in the energy storage device, and the real-time temperature of the corresponding detection points is collected. The real-time temperature is numerically compared with the corresponding preset real-time temperature threshold. If the real-time temperature exceeds the preset real-time temperature threshold, it indicates that the current temperature performance of the corresponding detection point is poor, and the corresponding detection point is judged to be in a temperature danger state;

[0053] The total time that the corresponding detection point is in the temperature danger state within the unit time is obtained and marked as the temperature danger point table value, and the ratio of the average temperature value of the corresponding detection point within the unit time to the corresponding preset average temperature threshold is marked as the temperature condition point table value;

[0054] The temperature risk point table value and the temperature condition point table value are numerically compared with the preset temperature risk point table threshold and the preset temperature condition point table threshold. If the temperature risk point table value or the temperature condition point table value exceeds the corresponding preset threshold, indicating that the temperature of the corresponding detection point is abnormal within a unit time, the corresponding detection point is marked as an alarm point; if there is an alarm point in the energy storage device, it indicates that the temperature performance of the energy storage device is poor and there are great safety hazards, and a temperature abnormality alarm signal is generated.

[0055] Furthermore, if there is no alarm point in the energy storage device, the temperature danger point table values ​​of all detection points in the energy storage device are averaged to obtain the temperature alarm value of the energy storage device, and the temperature condition point table values ​​of all detection points in the energy storage device are averaged to obtain the temperature inspection value of the energy storage device;

[0056] And collect the real-time number ratio of detection points in the energy storage device that are in a temperature danger state and mark them as the temperature danger number ratio, and mark the total time duration of the energy storage device's temperature danger number ratio exceeding a preset temperature danger number ratio threshold in a unit time as the energy storage device temperature abnormality value;

[0057] By formula The temperature warning value NP, the temperature detection value NL and the temperature abnormal value NS of the energy storage device are numerically calculated to obtain the temperature evaluation value LX of the energy storage device; wherein aq1, aq2 and aq3 are preset proportional coefficients with values ​​greater than zero, and the larger the value of the temperature evaluation value LX of the energy storage device, the worse the temperature condition of the energy storage device is in general, and the greater the operating risk of the energy storage device;

[0058] The temperature evaluation value LX of the energy storage device is numerically compared with the preset temperature evaluation threshold of the energy storage device. If the temperature evaluation value LX of the energy storage device exceeds the preset temperature evaluation threshold of the energy storage device, it indicates that the temperature condition of the energy storage device is generally poor. The greater the operating risk of the energy storage device, the temperature abnormality alarm signal is generated.

[0059] The regional threat assessment module analyzes the security threat level of the area where the energy storage equipment is located to determine whether to generate a regional high threat signal, and sends it to the regulatory warning end when the regional high threat signal is generated. The regulatory warning end issues a corresponding warning when receiving the regional high threat signal, which can comprehensively evaluate the regional threat of the location of the energy storage equipment and issue a timely warning to remind supervisors to strengthen the monitoring and control of the corresponding energy storage equipment, further ensure the energy storage safety of the energy storage equipment, and significantly reduce the management difficulty of supervisors; the specific operation process of the regional threat assessment module is as follows:

[0060] The location of the energy storage device is obtained, and the environmental parameters (including environmental temperature, humidity, smoke concentration and other parameters) that need to be monitored at the location of the energy storage device are marked as target parameters. The real-time monitoring data of the corresponding target parameters are collected, and the real-time monitoring data of the target parameters are compared with the corresponding preset data requirements. If the real-time monitoring data does not meet the corresponding preset data requirements, indicating that the corresponding target parameters pose a greater threat to the safe operation of the energy storage device, the corresponding target parameters are marked as threat parameters;

[0061] If there are threat parameters in the environment where the energy storage device is located, the energy storage device is judged to be in an unsafe state; the total time the energy storage device is in an unsafe state per unit time is obtained and marked as an unsafe detection value, and the unsafe detection value is numerically compared with the preset unsafe detection threshold. If the unsafe detection value exceeds the preset unsafe detection threshold, it indicates that the safe operation of the energy storage device is seriously threatened, and a regional high threat signal is generated.

[0062] Furthermore, if the non-safety detection value does not exceed the preset non-safety detection threshold, the impact information of the energy storage device in unit time (i.e., the relevant information of the collision impact of the energy storage device) is collected, and the duration GN of the corresponding impact process, the maximum impact energy GW (i.e., the maximum impact force of the energy storage device during the corresponding impact process) and the average impact energy GP (i.e., the average impact force of the energy storage device during the corresponding impact process) are numerically calculated by the formula GY=pu1*GN+(pu2*GW+pu3*GP) / pu1 to obtain the energy storage device damage value GY;

[0063] Among them, pu1, pu2, and pu3 are preset proportional coefficients with values ​​greater than zero, and the larger the value of the energy storage device damage value GY, the greater the damage caused to the energy storage device by the corresponding impact process; the energy storage device damage value GY is numerically compared with the preset energy storage device damage threshold. If the energy storage device damage value GY exceeds the preset energy storage device damage threshold, it indicates that the corresponding impact process has caused greater damage to the energy storage device, and the corresponding impact process is marked as a damaging process;

[0064] If there is a damage process in a unit time, it indicates that the safe operation of the energy storage device is seriously threatened, and a regional high threat signal is generated; if there is no damage process in a unit time, the number of impact processes involved in the energy storage device in a unit time is marked as the energy storage device collision detection value;

[0065] The monitoring value RL of the energy storage device is obtained through monitoring identification decision analysis, specifically: a circle with a radius of R1 is drawn with the energy storage device as the center, and the drawn circular area is marked as the monitoring area; the monitoring area is monitored by a camera, and when a moving target (including animals and personnel to be monitored, etc.) appears in the monitoring area, it is locked;

[0066] The number of times a moving target appears in the monitoring area within a unit time is collected and marked as the motion capture frequency, and the moving speeds of all moving targets appearing in the monitoring area within a unit time are averaged to obtain a regional motion speed detection value, and the minimum distance values ​​of all moving targets from the energy storage device to the monitoring area within a unit time are averaged to obtain a regional motion low distance value;

[0067] By formula The motion capture frequency RP, the regional motion speed detection value RY and the regional motion low distance value RS are numerically calculated to obtain the energy storage device monitoring value RL; wherein sw1, sw2 and sw3 are preset proportional coefficients with values ​​greater than zero, and the larger the value of the energy storage device monitoring value RL, the worse the regional condition of the monitoring area is, and the more easily the energy storage device is damaged;

[0068] By formula The non-safety detection value FM, the energy storage device collision detection value TL and the energy storage device monitoring value RL are numerically calculated to obtain the regional threat coefficient QX; wherein ru1, ru2 and ru3 are preset proportional coefficients with values ​​greater than zero, and the larger the value of the regional threat coefficient QX, the more serious the regional threat of the energy storage device is in general;

[0069] The regional threat coefficient QX is numerically compared with the preset regional threat coefficient threshold; if the regional threat coefficient QX exceeds the preset regional threat coefficient threshold, it indicates that the regional threat of the location of the energy storage device is relatively serious, and a regional high threat signal is generated.

[0070] Embodiment 2: Figure 2 As shown, the difference between this embodiment and the first embodiment is that the supervision and early warning end is connected to the inspection monitoring transmission module and the inspection execution decision module in communication, the inspection monitoring transmission module obtains the distribution area of ​​all energy storage devices that need to be supervised, monitors the inspection of the inspection personnel on the distribution area of ​​all energy storage devices, and sends the inspection monitoring information to the inspection execution decision module and the supervision and early warning end;

[0071] The inspection execution decision module conducts decision analysis on the inspection performance of the distribution area of ​​all energy storage devices during the inspection period (preferably, the inspection period is twenty-one days), generates an inspection alarm signal or an inspection qualified signal through analysis, and sends the inspection alarm signal or the inspection qualified signal to the supervision and early warning end. When the supervision and early warning end receives the inspection alarm signal, it issues a corresponding early warning to remind the supervisor to subsequently strengthen the management and control of the inspectors and the inspection and supervision of the energy storage equipment, which is conducive to ensuring the energy storage safety of the energy storage equipment. The specific analysis process of the inspection execution decision module is as follows:

[0072] The number of times the corresponding energy storage device generates abnormal power alarm signals, abnormal temperature alarm signals, and high regional threat signals in the previous adjacent detection period is obtained and marked as power alarm values, temperature alarm values, and threat alarm values, respectively;

[0073] The power alarm value MY, the temperature alarm value NX and the threat alarm value XR are numerically calculated by the formula HW=(c1*MY+c2*NX+c3*XR) / 3 to obtain the inspection judgment value HW of the corresponding energy storage device; wherein c1, c2 and c3 are preset weight coefficients with values ​​greater than zero, and the larger the inspection judgment value HW is, the greater the overall operation risk of the corresponding energy storage device in the previous adjacent detection period is, and the more it is necessary to strengthen the inspection and supervision of the corresponding energy storage device;

[0074] Several groups of preset patrol judgment value ranges are set in advance, and each group of preset patrol judgment value ranges corresponds to a group of preset energy storage device patrol abnormality thresholds; wherein, the larger the value of the preset patrol judgment value range, the smaller the value of the preset energy storage device patrol abnormality threshold matched therewith, and the values ​​of the preset energy storage device patrol abnormality thresholds are all positive numbers;

[0075] Compare the inspection judgment value HW of the corresponding energy storage device with all preset inspection judgment value ranges one by one, and mark the preset energy storage device inspection abnormality threshold corresponding to the preset inspection judgment value range containing the corresponding inspection judgment value HW as the optimal energy storage device inspection abnormality threshold;

[0076] When there are no inspectors in the distribution area of ​​the corresponding energy storage equipment, it is determined that the energy storage equipment is in an uninspected state; all single durations of the corresponding energy storage equipment in the uninspected state during the detection period are obtained, and all single durations of the corresponding energy storage equipment in the uninspected state during the detection period are summed up to obtain an uninspected time value, and the number of occurrences of the single duration exceeding the preset single duration threshold during the detection period is marked as an uninspected value, and the single duration with the largest value during the detection period is marked as an uninspected amplitude value;

[0077] The energy storage equipment patrol abnormality value SY is obtained by numerically calculating the unmanned patrol time value ZW, unmanned patrol danger value ZS and unmanned patrol amplitude value ZF through the formula SY=uy2*ZS+(uy1*ZW+uy3*ZF) / 2; wherein uy1, uy2 and uy3 are preset proportional coefficients, uy2>uy3>uy1>0; and the larger the value of the energy storage equipment patrol abnormality value SY, the worse the patrol performance of the corresponding energy storage equipment during the detection period;

[0078] Compare the patrol value of the energy storage device with the optimal patrol threshold of the energy storage device corresponding to the energy storage device. If the patrol value of the energy storage device exceeds the optimal patrol threshold of the energy storage device, it indicates that the patrol performance of the corresponding energy storage device during the detection period is poor, and the patrol evaluation symbol LP-1 is assigned to the corresponding energy storage device.

[0079] The number of energy storage devices assigned with the patrol evaluation symbol LP-1 during the detection period is obtained and the ratio thereof to the total number of energy storage devices that need to be supervised is calculated to obtain the patrol execution coefficient, and the ratio of the patrol abnormality value of the energy storage device to the patrol abnormality threshold of the corresponding optimal energy storage device is marked as the energy storage device patrol occupancy value, and the energy storage device patrol occupancy values ​​of all energy storage devices that need to be supervised are averaged to obtain the patrol performance coefficient;

[0080] The inspection execution coefficient and the inspection performance coefficient are numerically compared with the preset inspection execution coefficient threshold and the preset inspection performance coefficient threshold respectively. If the inspection execution coefficient or the inspection performance coefficient exceeds the corresponding preset threshold, indicating that the inspection supervision effect during the detection period is poor, then a patrol alarm signal is generated; if the inspection execution coefficient and the inspection performance coefficient do not exceed the corresponding preset threshold, indicating that the inspection supervision effect during the detection period is relatively poor, then a patrol qualified signal is generated.
