BRIEF DESCRIPTION OF THE DRAWINGS

[0060] Figure 1 The present invention is a flowchart of the method for defining the safety service boundary of electrical facilities in high-rise buildings. DETAILED DESCRIPTION

[0061] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0062] Embodiment 1:

[0063] This embodiment is based on the existing building electrical system (directly obtaining the public electrical facility working data and environmental data from the existing building electrical system) and the normal public electrical facility working data stored in the database, as well as the equipment and equipment association data recorded in the electrical facility knowledge graph, and then uses a computer to analyze and compare the data to obtain corresponding results.

[0064] The method for defining the safe service boundary of electrical facilities in high-rise buildings includes the following steps:

[0065] Collecting the working data of the public electrical facilities in real time, and comparing the working data of the public electrical facilities with the preset corresponding working threshold interval, and judging whether the public electrical facilities are faulty according to whether the working data of the public electrical facilities are within the working threshold interval;

[0066] The public electrical facility operating data includes current data, voltage data, temperature data and noise data collected from the building electrical system when the public electrical facilities are operating.

[0067] Working data does not include starting and stopping, and during normal use, building public facilities are in standby mode all the time except when damaged, and the power is not directly cut off. Starting and stopping are usually manually controlled by relevant staff during maintenance or repair.

[0068] The building electrical system is an existing building power facility supervision system, and its original function is to obtain the working data of public electrical facilities and the environmental data in the building. This patent obtains data directly from the building electrical system without the need to install power data collection equipment separately. Therefore, the overall cost is relatively low.

[0069] The working threshold interval includes the fluctuation threshold interval (in normal operation, data fluctuations have certain rules and are within a certain range. Instantaneous changes in data are sudden situations) and the range threshold interval (i.e., the upper and lower limits in normal operation);

[0070] The steps of comparing the acquired working data of the public electrical facilities with the working threshold interval to determine whether the public electrical facilities are faulty are as follows:

[0071] Compare all the working data of the public electrical facilities with the corresponding range threshold intervals, and when the working data of the public electrical facilities are outside the range threshold interval, determine that the public electrical facilities are faulty;

[0072] The range threshold interval is preset to ,in is the standard range threshold interval under normal temperature and humidity environment, and hjxs is the set environmental impact coefficient;

[0073] The hjxs of noise, voltage and current are set to 1, because normal environmental changes have little impact on them. Therefore, hjxs is mainly used to adjust the temperature. For example, the temperature difference between noon in summer and noon in winter is 30°C. The external temperature difference will make the temperature of the equipment different during operation. The average temperature of the equipment with the same working intensity in summer is 10-15°C higher than that in winter. Therefore, hjxs is needed for adjustment.

[0074] When the working data of the public electrical facilities is within the range threshold interval, the change ratio of the working data of the public electrical facilities within the range threshold interval is calculated. When the change ratio is outside the fluctuation threshold interval, it is determined that the public electrical facilities have a fault. When the change ratio is within the fluctuation threshold interval, it is determined that the public electrical facilities have no fault.

[0075] The formula for calculating the change ratio of public electrical facility working data is as follows:

[0076] ;

[0077] Where Bhbl is the change ratio of the working data of public electrical facilities, is the working data of public electrical facilities collected at time t, It is the working data of public electrical facilities collected at time t-1.

[0078] Under normal circumstances, the time difference between time t and time t-1 is 5-15 seconds.

[0079] For example, the temperature of the lamp is 45°C at time t-1 and 58°C at time t. The normal operating temperature of the lamp is [40, 60], and there is 10 seconds between time t-1 and time t. , which exceeds the normal 0.05%, and is therefore a fault condition.

[0080] When there is a public electrical facility fault, the fault risk level is calculated, and the calculated fault risk level is compared with the set risk diffusion threshold interval, and the corresponding safety margin calculation strategy is executed according to the risk diffusion threshold interval where the fault risk level is located;

[0081] When calculating the fault risk level, first calculate the ratio of the working data of the faulty public electrical facilities with the largest distance between the working data and the boundary of the set range threshold interval. or the largest percentage change in the faulty utility work data , then according to or Calculate the failure risk level;

[0082] Since there are four groups of working data collected, there may be multiple groups of data anomalies, and the data with the largest change ratio is used when calculating the anomalies.

[0083] Therefore, it is necessary to calculate all Czbl or all Bhbl and then get the maximum value. or ,according to or Calculate the failure risk level.

[0084] The formula for calculating the ratio Czbl of the distance between the working data and the boundary of the set range threshold interval in the working data of the faulty public electrical facilities is as follows:

[0085] ;

[0086] For example, the temperature of the lamp measured at time t is 68°C under normal temperature, and the normal operating temperature of the lamp is [40, 60]. .

[0087] The fault risk level Gzfx is based on Calculated Or based on Calculated ;

[0088] The calculation formula of the failure risk level is as follows:

[0089] ;

[0090] In the formula, Based on The calculated fault risk level when the working data of the public electrical facilities is within the range threshold interval, Czxs is the coefficient of the distance ratio between the working data and the boundary of the set range threshold interval affecting the fault risk level, Fxdj is the danger level of the public electrical facilities themselves, Hjxs is the possibility of the fault risk occurring, Based on The fault risk level calculated when the calculated working data of the public electrical facilities is within the range threshold interval, and Blxs is the coefficient of the change ratio of the working data of the public electrical facilities affecting the fault risk level.

[0091] For example: Czxs is 0.2, Fxdj is 1, Hjxs is 0.42, Czbl is 0.16%, the calculated .

[0092] For example: Blxs is 0.15, Fxdj is 1, Hjxs is 0.42, Bhbl is 0.26%, the calculated .

[0093] The calculation formula for the probability of failure risk occurrence is as follows:

[0094] ;

[0095] In the formula, n is the type of environmental data collected, k is the type of data reflecting the occurrence of dangerous situations, is the i-th type of environmental data collected in addition to the data reflecting the occurrence of fire, is the preset standard value of the i-th type of environmental data, is the coefficient of the i-th type of failure risk affecting the probability of occurrence, n>k;

[0096] Commonly collected types of environmental data include infrared temperature data, smoke data, special gas data and humidity data.

[0097] Among them, smoke data and special gas data are data types that reflect the occurrence of dangerous situations. When the monitored smoke data and special gas data exceed the set value, it means that a dangerous situation has occurred. At this time, Hjxs takes 1.

[0098] For example, if the collected temperature data is 40℃, the standard temperature is 25℃, the corresponding Hjbl of the temperature is 0.6, the collected humidity is 80%, the standard humidity is 40%, the corresponding Hjbl of the humidity is 0.8, the calculated .

[0099] The probability of a failure risk occurring when no data reflecting a dangerous situation is detected, The probability of a failure risk occurring when data reflecting the occurrence of a dangerous situation is detected.

[0100] The calculation formula of the hazard level coefficient Fxdj of public electrical facilities themselves is as follows:

[0101] ;

[0102] In the formula, is the ceiling function, x is , q is the type of parameters of public electrical facilities that affect the hazard level, The parameter data of the mth type of public electrical facilities affecting the hazard level to be detected, is the proportional coefficient of converting the mth parameter data into the danger level, The number of hazardous properties of public electrical facilities.

[0103] The types of intrinsic parameters that affect the hazard level include volume and power, and the hazardous properties of public electrical facilities include flammable, explosive, toxic, and radioactive.

[0104] For example, lithium batteries are flammable and explosive. Take 2.

[0105] For example, the volume of the building backup power supply is 0.6m³, the corresponding Hsxs is 2, the power is 12 kW, and the corresponding Hsxs is 0.6. 6.

[0106] The risk diffusion threshold range includes a separate supervision range , some regulatory areas and targeted regulatory areas ;

[0107] The value range of is 0.25-0.35, and the value range of D is 2-4.

[0108] The corresponding safety margin calculation strategy is implemented according to the risk diffusion threshold interval of the fault risk level as follows:

[0109] When Gzfx is in a separate regulatory zone When the data collection frequency of the faulty public electrical facilities is adjusted to more than 3 times in 10 seconds, the danger range of the faulty public electrical facilities is calculated separately;

[0110] When Gzfx is in a partial regulatory zone When the fault is detected, the associated equipment is searched from the knowledge graph of the database, and the data collection frequency of the faulty public electrical facilities and the associated equipment is adjusted to more than 5 times in 10 seconds, the danger range of the faulty public electrical facilities is calculated, and the data collection frequency of the electrical facilities in the danger range is adjusted to more than 3 times in 10 seconds;

[0111] This situation is dangerous and requires real-time attention. When the danger increases to the targeted supervision interval, the strategy of the targeted supervision interval is adopted. When the danger decreases to the separate supervision interval, the strategy of the separate supervision interval is adopted.

[0112] It is possible to transition directly between the individual supervision zone and the partial supervision zone, but once it is determined to be a targeted supervision zone, it will not be downgraded and will remain in a power-off state unless there is human power to release it.

[0113] When Gzfx is in the targeted regulatory zone When the faulty public electrical facilities and related equipment are disconnected from the power supply, the danger range of the faulty public electrical facilities is calculated, the power supply of all electrical facilities within the danger range of the faulty public electrical facilities is disconnected, and the frequency of environmental data collection within the danger range is adjusted to more than 3 times in 10 seconds.

[0114] The power supply of all electrical facilities does not include data acquisition equipment. The data acquisition equipment is powered separately, has little harm, and is required to collect data. Therefore, it is in a state of constant operation.

[0115] This situation is very dangerous. In order to reduce losses, the power supply to nearby electrical facilities should be disconnected.

[0116] The calculation formula of danger range is as follows:

[0117] ;

[0118] Where Wxfw is the danger range, ksxs is the danger diffusion coefficient, and the boundary of the danger range is the safety service boundary of electrical facilities in high-rise buildings.

[0119] For example, ksxs is 30, the lighting 0.0837, the danger zone is 2.511 meters with the lighting fixture as the center. The value range of ksxs is 20-50.

[0120] Collect the results of the safety boundary calculation strategy, mark the calculation results on the high-rise building drawings, and activate the warning device according to the results of the safety boundary calculation strategy until the fault is resolved;

[0121] Mark the calculated danger range of faulty public electrical facilities on the high-rise building drawings, using a preset color according to the risk level of the marked location;

[0122] The calculation formula for the risk level Fxdj of the marked position within the danger range is as follows:

[0123] ;

[0124] Where o is the number of dangerous areas of the faulty public electrical facilities at the marked location, is the fault risk level of the faulty public electrical facilities corresponding to the zth hazard range, is a constant coefficient, , Jz is the straight-line distance from the marked position to the zth faulty public electrical facility, To mark the number of walls between the location and the faulty public electrical facilities, is the impact resistance grade of the u-th wall, is the distance between the uth wall at the marked position and the faulty public electrical facility on the straight line;

[0125] when hour, Take 0.

[0126] Because the wall can only eliminate the risk in that direction at most and cannot cause any optimization.

[0127] When Gzfx is in a separate regulatory zone When the fault is cleared, the faulty public electrical facilities are judged to be restored to no fault based on the result of the calculation of the collected data;

[0128] When Gzfx is in a partial regulatory range When the fault is cleared, the fault is solved by judging that all power facilities and power equipment are fault-free according to the calculation results of the collected data;

[0129] When Gzfx is in the targeted regulatory range When the fault is cleared, the fault is cleared by manually checking that the faulty public electrical facilities and related equipment are normal, and after connecting the faulty public electrical facilities, it is determined based on the calculation results of the collected data that all power facilities and power equipment are fault-free.

[0130] This situation is quite serious and requires a thorough investigation by manpower before power can be turned on. Supervision is also required after power is turned on to avoid further failures.

[0131] Obtain the relevant data of public electrical facility faults and the results of safety boundary calculation strategies, and summarize and store the acquired data in the database.

[0132] It is convenient to adjust the corresponding coefficients according to the data in the future, further optimize the method, and further improve the effect of the method.

[0133] The above formula is a formula obtained by collecting a large amount of data and performing software simulation to obtain the most recent real situation. The preset parameters in the formula are set by technicians in this field according to actual conditions.
