Obviously, the embodiments described 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 making creative efforts should fall within the scope of protection of the present invention.

It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments described herein can be implemented in an order other than that illustrated or described herein.

For example, a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0028] According to an embodiment of the present invention, an electrical data acquisition method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0029] In this embodiment, a method for collecting electrical data is provided, which can be used in electronic equipment. Figure 1 is a flow chart of an electrical data acquisition method according to an embodiment of the present invention. Figure 1 As shown, the method includes the following steps:

[0030] The embodiment of the present invention provides an electrical data acquisition method, such as Figure 1 As shown, the method includes the following steps:

[0031] Step S101: Freeze and cache the electrical parameters sampled by the remote monitoring terminal. The remote monitoring terminal can be an existing smart meter or other device, such as an RS485 three-phase rail meter, or other device that can realize electrical parameter monitoring and collection. Specifically, the remote monitoring terminal is provided with monitoring elements such as a residual current transformer, a current transformer, a voltage transformer, a temperature sensor, an electrical fire alarm device, and a safety power supply, which can realize the monitoring and sampling of electrical parameters including: parameter type, which includes voltage, current, active power, reactive power, apparent power, power factor, frequency, temperature, electrical fire alarm, safety power supply and other electrical parameters. After completing the sampling of the electrical parameters, the electrical parameters sampled by the remote monitoring terminal are frozen, that is, the sampled electrical parameters are cached in the remote monitoring terminal.

[0032] The remote monitoring terminal can collect the electrical parameters of the device under test. Therefore, the device type can also be obtained as a type of electrical parameter. This device type includes the device fire probability priority level, device value, and device impact. For each device, after obtaining the device parameters, such as the device name, the device type can be compared with the pre-set type to determine the device fire probability priority level, device value, and device impact.

[0033] Step S102: Determine the transmission time offset of the electrical parameters based on the type of the remote monitoring terminal and the type of the electrical parameters. Specifically, to avoid a sudden increase in bandwidth when data is transmitted simultaneously, different transmission time offsets are set for the cached electrical parameters, and the electrical parameters are transmitted separately in a serial manner.

[0034] In one embodiment, the transmission time offset is set based on the type of the remote monitoring terminal and the type of the electrical parameter. Specifically, a first transmission time offset is first set based on the type of the remote monitoring terminal; a second transmission time offset for the corresponding electrical parameter is then determined based on the type of the electrical parameter; and finally, the transmission time offset for the electrical parameter sampled by the remote monitoring terminal is determined by combining the first and second transmission time offsets.

[0035] Due to the diverse nature of current remote monitoring terminals, i.e., the existence of multiple types of remote monitoring terminals in actual applications, different transmission time offsets can be set for different remote monitoring terminals. Furthermore, different types of remote monitoring terminals may be used in different application scenarios, and thus, corresponding transmission time offsets can be set for remote monitoring terminals in different application scenarios. For example, for remote monitoring terminals used in factories and residences, the transmission time offset for remote monitoring terminals in residences can be set to be greater than the transmission time offset for remote monitoring terminals in factories.

[0036] Furthermore, in addition to the type of remote monitoring terminal, since a single remote monitoring terminal can monitor and sample multiple electrical parameters, different transmission time offsets can be set based on the different electrical parameter types. For example, when the sampled electrical parameters include voltage, current, active power, reactive power, apparent power, power factor, frequency, temperature, electrical fire alarm, and safety power supply, the transmission time offset for electrical fire alarms can be set larger, while the transmission time offsets for voltage, current, and other parameters can be set smaller, depending on the actual application. Furthermore, since the electrical parameters also include the type of device being measured, when determining the second transmission time offset based on the electrical parameters, factors such as the device type's priority level for fire probability, the device's value, and the device's impact can also be considered. In other words, the second transmission time offset is determined based on both the parameter type within the electrical parameters and the device type being measured.

[0037] For the electrical parameters sampled by the remote monitoring terminal, the first transmission time offset corresponding to the remote monitoring terminal and the second transmission time offset corresponding to the electrical parameters can be comprehensively considered, and the transmission time offset of the electrical parameters can be determined by weighted calculation. Specifically, the time offset of the determined electrical parameters includes the transmission time offset of each parameter in the parameter type of the device under test. For example, the parameter types collected for a certain device under test include smoke detection, temperature, and instantaneous current. The transmission time offset corresponding to the smoke detection is time t, the transmission time offset corresponding to the temperature is time t+offest(1), and the transmission time offset corresponding to the instantaneous current is time t+offest(2), wherein the measurement unit of t can be one of hours, minutes, seconds, milliseconds, and microseconds, the measurement unit of offest is one of hours, minutes, seconds, milliseconds, and microseconds, and the interval between offest(1) and offest(2) is any mathematical data, including any of 1, 0.01, and 0.001. For example, the instantaneous smoke detection is 2 minutes, the temperature is 2.01 minutes, and the instantaneous current is 2.03 minutes.

[0038] Step S103: Upload the sampled electrical parameters to the cloud platform based on the transmission time offset of the electrical parameters. Once the transmission time offset of the electrical parameters is determined, the electrical parameters are uploaded and saved based on the transmission time offset. For example, if the electrical parameters include current and temperature, and the transmission time offset of current is 10 seconds and the transmission time offset of temperature is 5 seconds, then the current data will be uploaded 10 seconds after the current is frozen, and the temperature data will be uploaded 5 seconds after the temperature is frozen.

[0039] The electrical data acquisition method provided by the present invention freezes and caches sampled electrical parameters and uploads them to a cloud platform based on a predetermined transmission time offset. By freezing data and setting a transmission time offset, this method can break down the large number of data blocks being uploaded simultaneously into a data transmission process that prioritizes serial transmission and supplements parallel transmission, reducing the instantaneous data transmission bandwidth and increasing the stability of the data transmission process.

[0040] In one embodiment, if Figure 2 As shown, before freezing and caching the electrical parameters sampled by the remote monitoring terminal, the following steps are included:

[0041] Step S201: Determine the electrical parameters sampled by the remote monitoring terminal based on the business scenario of the remote monitoring terminal. Specifically, according to the above steps, for a single remote monitoring terminal, which contains multiple sensors, it is possible to monitor multiple types of electrical parameters. However, in some scenarios, it is not necessary to obtain all electrical parameters. Therefore, the electrical parameters sampled by the remote monitoring terminal can be set according to the business scenario of the remote monitoring terminal. For example, in a certain scenario, only the electrical parameter temperature is required, and the electrical parameter sampled by the remote monitoring terminal is set to temperature.

[0042] Step S202: Sampling the corresponding electrical parameters in the remote monitoring terminal according to a preset sampling period. Specifically, since the sampled electrical parameters are uploaded with a transmission time offset, a sampling period for the electrical parameters can be set, eliminating the need for real-time sampling. In one embodiment, similar to the determination of the transmission time offset, the preset sampling period can also be determined based on the type of remote monitoring terminal and the type of electrical parameter; that is, the preset sampling period can be set to the same value as the transmission time offset.

[0043] In one embodiment, if Figure 3 As shown, uploading the sampled electrical parameters to the cloud platform according to the transmission time offset of the electrical parameters includes the following steps:

[0044] Step S301: Compare the sampled electrical parameters with the preset electrical parameters. Specifically, while uploading the electrical parameters according to the set transmission time offset can avoid bandwidth surges, if there are problems with the monitored data, timely acquisition may not be possible. Therefore, after sampling the electrical parameters, the sampled electrical parameters are first compared with the preset electrical parameters. The preset electrical parameters can be determined based on actual conditions.

[0045] Step S302: When the sampled electrical parameters meet the preset range, the sampled electrical parameters are uploaded to the cloud platform according to the transmission time offset of the electrical parameters. When the sampled electrical parameters meet the preset range, it means that there is no problem with the device monitored by the remote monitoring terminal, and the upload can be carried out according to the set transmission time offset.

[0046] Step S303: When the sampled electrical parameters do not meet the preset range, the transmission time offset of the electrical parameters is reduced. Specifically, when the sampled electrical parameters do not meet the preset range, it indicates that there is a problem with the device being monitored by the remote monitoring terminal. For example, if the currently sampled current exceeds the preset range, there may be a problem with the currently monitored device. In this case, the current current electrical parameters can be immediately uploaded to the cloud platform. At the same time, the transmission time offset of the current electrical parameters sampled subsequently is reduced. This allows for a comprehensive judgment of whether a problem has occurred based on subsequent current measurements.

[0047] Step S304: Upload the sampled electrical parameters to the cloud platform based on the reduced transmission time offset. Specifically, the subsequently sampled electrical parameters are uploaded with the reduced transmission time offset. The cloud platform can perform a comprehensive analysis based on the uploaded electrical parameters. If it determines that there is no problem, it can restore the original transmission time offset and upload the electrical parameters again. If it determines that there is a problem, it can promptly conduct repairs.

[0048] In one embodiment, if Figure 4 As shown, the electrical data acquisition method is implemented using the following process: for the electrical parameters sampled by multiple remote monitoring terminals, the transmission time offset (offset) of different types of electrical parameters in each remote monitoring terminal is set according to the type of remote monitoring terminal and the type of electrical parameters, and then the data is frozen and cached at the moment of sampling by the remote monitoring terminal. The electrical parameters are transmitted and uploaded within the corresponding time after freezing according to the set transmission time offset. Finally, the cloud platform saves, processes and calculates the electrical parameters after receiving them.
