[0019] In order to solve the problems of the prior art, the present application provides a method for identifying the remaining service life of electrical equipment on a load identification intelligent circuit breaker and a load identification intelligent socket. Specifically, the problems to be solved by the device detection method of the present application include but are not limited to: 1. Perform refined calculations on the current and voltage data of terminal electrical equipment to identify the remaining service life of the terminal electrical equipment.

[0020] 2. For large and small power terminal electrical equipment, the same accuracy and the same rate of detection are achieved.

[0021] Please refer to Figure 1 , Figure 1 It is a flow chart of an embodiment of a device detection method provided by the present application.

[0022] The device detection method of the present application is applied to a device detection device, wherein the device detection device of the present application can be a server, a terminal device, or a system composed of a server and a terminal device. Accordingly, the various parts included in the device detection device, such as various units, subunits, modules, and submodules, can all be set in the server, can all be set in the terminal device, or can be set in the server and the terminal device respectively.

[0023] Furthermore, the above-mentioned server can be hardware or software. When the server is hardware, it can be implemented as a distributed server cluster consisting of multiple servers, or it can be implemented as a single server. When the server is software, it can be implemented as multiple software or software modules, such as software or software modules used to provide distributed servers, or it can be implemented as a single software or software module, which is not specifically limited here.

[0024] It should be noted that the equipment detection device of the present application may be an intelligent terminal equipped with a load identifying intelligent circuit breaker and / or a load identifying intelligent socket.

[0025] like Figure 1 As shown, the specific steps are as follows: Step S11: obtaining current voltage data and current data of the electrical equipment in the current time period.

[0026] In the embodiment of the present application, the aging of the electronic components of the electrical equipment will be reflected in the changes in the resistance, capacitance, inductance, and other parameters of all the electronic components in the electrical equipment. The changes in these parameters will be reflected in the changes in the current size, power factor, and phase relationship between the working current and the working voltage of the entire electrical equipment when it is working.

[0027] Therefore, the equipment detection device needs to collect the current voltage and current data of the electrical equipment in the current time period. Generally speaking, the current voltage and current data in the current time period should be at least one cycle or more than half a cycle of voltage and current data. By analyzing the periodic voltage and current, the error of life detection can be reduced and the accuracy of service life detection can be improved.

[0028] In a specific implementation, the load identification intelligent circuit breaker and the load identification intelligent socket have their own current and voltage detection circuits. This metering circuit will collect one single-point current data, i.e., a current data point, and a single-point voltage data, i.e., a voltage data point, per unit time. At the same time, this metering circuit will obtain relevant information such as power factor, AC frequency, and AC zero point.

[0029] Please refer to Figure 2 , Figure 2 It is a waveform diagram of an embodiment of voltage and current data provided by the present application.

[0030] like Figure 2As shown, the equipment detection device collects the AC current waveform and AC voltage waveform of a section of electrical equipment in use. The internal collection and metering circuit of the load identification intelligent circuit breaker and load identification intelligent socket can collect single-point voltage data and single-point current data every unit time. For example, taking the zero point of voltage as the starting point, collect 1 single-point current data A and 1 single-point voltage data U every 1mS. For example, the current data at t1 is recorded as A t1 , the voltage data at t1 is recorded as U t1 , the current data of t2 is recorded as A t2 , the voltage data at t2 is recorded as U t2 ...The current data at t20 is recorded as A t20 , the voltage data of t20 is recorded as U t20 .

[0031] At the same time, through the load identification intelligent circuit breaker and the internal metering circuit of the load identification intelligent socket (such as a metering chip, etc.), it is possible to directly obtain that the AC frequency is 50Hz and the zero point position of the AC.

[0032] Step S12: Based on the current voltage data, obtain the current correction coefficient.

[0033] In the embodiment of the present application, the equipment detection device determines the current correction coefficient for the current current data by correcting the current voltage data to a uniform standard AC voltage state.

[0034] Specifically, the equipment detection device determines the standard AC voltage according to the AC frequency used by the electrical equipment, wherein the AC frequency used by the electrical equipment is mainly collected and determined by the metering circuit inside the load identification intelligent circuit breaker and the load identification intelligent socket.

[0035] It should be noted that the period information of the standard AC voltage should be the same as the period information of the current voltage data, that is, the phase conditions of the voltage data of the two should be consistent, so as to facilitate the calculation of the correction coefficient of each phase point.

[0036] In a specific embodiment, the device detection device determines that the standard AC voltage is AC220V according to the AC frequency of 50Hz. The device detection device solves the waveform voltage value of the standard AC voltage according to the voltage value of 220V. Figure 2 Shown U t6 The standard value is 311.08V, which is converted from 220V through 1.414.

[0037] Furthermore, the equipment detection device calculates the waveform voltage value of the standard AC voltage at the same phase point, that is, the ratio of the standard voltage data point to the current voltage data point, as the correction coefficient of the phase point. For example, the equipment detection device compares the standard value with the actual value to obtain a specific ratio, which is recorded as the correction coefficient X, and X can be obtained. t6 =311.08 / U t6 .

[0038] Step S13: Correct the current current data using the current correction coefficient to obtain corrected current data.

[0039] In the embodiment of the present application, the equipment detection device uses the correction coefficient X and the current current data A at the same time point to perform correction calculation to obtain the corrected current data Y. For example, Y t6 =A t6 *X t6 .

[0040] Step S14: Based on the corrected current data and the initial current data of the initial time period, the service life information of the electrical equipment in the current time period is obtained.

[0041] In the embodiment of the present application, the device detection device compares the corrected current data with the initial current data of the initial time period, and generates or determines the service life information of the electrical equipment in the current time period based on the difference between the two. The initial time period may be the current data within a preset time period collected when the electrical equipment is powered on for the first time.

[0042] Specifically, the equipment detection device stores the series data of the first power-on of the terminal equipment as the original data in the load identification intelligent circuit breaker and the load identification intelligent socket, which is recorded as Y t1-1 , Y t2-1 ...Y t19-1 , Y t20-1 ...Y tn-1 It should be noted that the initial current data also needs to be corrected by the correction coefficient before it can be saved.

[0043] Furthermore, when the equipment detection device is powered on and used in the subsequent electrical equipment, the load identification intelligent circuit breaker and the load identification intelligent socket will continue to obtain a new series of data for a certain time period T, that is, the current time period. t1-T , Y t2-T ...Y t19-T , Y t20-T ...Y tn-T .

[0044] The equipment detection device can determine the service life information of the current time period by directly comparing the current difference between the two. For example, the larger the current difference, the shorter the remaining service life of the electrical equipment.

[0045] This application provides a quantitative solution for service life information. Figure 3 , Figure 3 yes Figure 1 A specific flow chart of step S14 of the device detection method is shown.

[0046] like Figure 3 As shown, the specific steps are as follows: Step S141: determining a life coefficient based on a current ratio between the corrected current data and the initial current data at a corresponding time point.

[0047] In the embodiment of the present application, the equipment detection device performs an operation and induction on the series of data obtained subsequently and the series of data when powered on for the first time to obtain data Z, which is recorded as life data.

[0048] Specifically, the equipment detection device needs to calculate the ratio between the corrected current data point and the initial current data point at each time point as the life coefficient at that time point, as follows: Z1=Y t1-T / Y t1-1 Z2=Y t2-T / Y t2-1 Zn=Y tn-T / Y tn-1 Step S142: averaging all life coefficients to obtain life parameters.

[0049] In the embodiment of the present application, the equipment detection device averages all the life coefficients obtained in step S141, and the average value is recorded as the life parameter or life data: Z=(Z1+Z2+……Zn) / n Step S143: Obtaining the service life information of the electrical equipment in the current time period based on the service life parameter.

[0050] In the embodiment of the present application, the equipment detection device determines whether the electrical equipment is aging based on the life parameter calculated in step S142.

[0051] Specifically, the closer the life parameter Z value is to 1, the longer the remaining service life of the electrical equipment is. The further the Z value deviates from 1, the shorter the remaining service life of the electrical equipment is.

[0052] Furthermore, the equipment detection device can also use the normal use parameter range to perform the following refined processing on the life parameter Z: For example, when 0.98≤Z≤1.02, the equipment detection device determines that the remaining service life of the electrical equipment is normal, and reports and stores the good operation information status of the equipment.

[0053] When Z>1.02 or Z<0.98, the equipment detection device determines that the remaining service life of the electrical equipment is abnormal and aging may occur.

[0054] Furthermore, when it is determined that the electrical equipment may be aging, the equipment detection device may continue to make a more refined judgment on the life parameter Z: The equipment detection device reads Z1, Z2...Zn, reads several rounds continuously, eliminates interference, and confirms that Z>1.02 or Z<0.98 always exists, then compares each data of Z1, Z2...Zn read: When more than 5% of the data are greater than 1.05 or less than 0.95, the equipment detection device determines that the electrical equipment is beginning to age, reports the equipment aging operation information status and stores it.

[0055] When more than 10% of the data are greater than 1.05 or less than 0.95, the equipment detection device determines that the electrical equipment is in a low-risk aging state, reports the equipment aging operation information status and stores it.

[0056] When more than 15% of the data are greater than 1.05 or less than 0.95, the equipment detection device determines that the electrical equipment is in a medium-risk aging state, reports the equipment aging operation information status and stores it.

[0057] When more than 20% of the data is greater than 1.05 or less than 0.95, the equipment detection device determines that the electrical equipment is in a high-risk aging state, reports the equipment aging operation information status and stores it.

[0058] Furthermore, the load-identifying intelligent circuit breaker and load-identifying intelligent socket software will issue prompts, reminding personnel to replace the terminal equipment used in time to avoid risks.

[0059] In the present application, the equipment detection device obtains the current voltage data and current current data of the electrical equipment in the current time period; based on the current voltage data, obtains the current correction coefficient; uses the current correction coefficient to correct the current data to obtain the corrected current data; based on the corrected current data and the initial current data of the initial time period, obtains the service life information of the electrical equipment in the current time period. Through the above-mentioned equipment detection method, the voltage and current data of the electrical equipment are detected, and the accuracy of the current data in evaluating the equipment life is improved by correction.

[0060] The device detection method of the present application uses the original data of current and voltage for detection, is not restricted by high-power load or low-power load, exhibits the same detection accuracy and the same detection rate, and covers a wider range of terminal electrical equipment that can be accurately detected.

[0061] The device detection method of the present application can complete the detection within at least one AC cycle. According to the 50 / 60Hz AC power used in my country at that time, the detection can be completed in at least 16.6ms, which is a faster detection speed.
