As shown in Figure 1, an intelligent power recording system. The smart power recording system includes a power consumption detection module 100 and a recording device 200 . The electricity consumption detection module 100 is used to detect the operation state of the electric equipment, generate and transmit the operation state data of the electric equipment and output it. The recording device 200 is used for receiving the operation state data of the electrical equipment, calculating the power consumption of the electrical equipment, and deriving power consumption data recording the power consumption of the electrical equipment.

The power detection module 100 includes a detection module 120 , a control module 140 and an output module 160 . The electricity consumption detection module 100 uses the detection module 120 to sample the current of the electrical equipment, and convert it into corresponding current data through an internal circuit. The control module 140 receives the data signal sent by the detection module 120, compares the data, and judges whether the current data exceeds the set threshold value. For some electrical equipment, even if it is not working, but the power is not cut off, it will still consume a small amount of power, and the corresponding detection module 120 will still detect a small current, so it is necessary to set a current threshold limit value for For distinction and judgment, the size of the threshold limit needs to be determined according to specific circumstances. If the current data exceeds the set threshold value, it means that the electrical equipment is in the running state, and the electrical equipment running status information of "electrical equipment running" is generated. If it is less than the set threshold limit, it means that the electrical equipment is not in operation. state, generating the operating status information of the electrical equipment of "the electrical equipment is out of operation", the control module 140 generates the operating status data of the electrical equipment that records the identification code and the operating status information of the electrical equipment, and its format is "identification code + power consumption Equipment running state information" and sent to the output module 160. The identification code identifies the power consumption detection module 100, and each power consumption detection module 100 has a unique identification code, which is in one-to-one correspondence with the name of the power consumption equipment. The output module 160 receives the information generated by the control module 140 and transmits it to the output module 210 of the recording device 200 through wireless communication (such as GPRS, WIFI and 3G, etc.), and can also be connected through wired communication.

The recording device 200 includes a receiving module 210 , a storage module 220 , a clock module 230 , a processor module 250 and an input unit 240 .

It is preferable that the power detection module is a power transformer. The storage module 220 includes a register 221 and a memory 222 . After the storage module 220 successfully receives the operating state data of the electrical equipment, it is stored in the register 221, and the processor module 250 reads the readings of the electric meter and the clock information in the clock module 230, stores them in the register 221, and sends the received electricity detection module 100 information, meter readings and clock information are summarized to obtain a piece of electricity consumption information, which records identification codes, operating status information of electrical equipment, clock information and meter readings, and finally stores the summarized electricity consumption information in the large Capacity memory 222. The power consumption of each electric device is obtained through the calculation program, and the power consumption data recording the power consumption of the electric device is generated. The format for recording electricity consumption information in the memory 222 is: identification code + operating status information of electric equipment + clock information + meter reading. The input unit 240 is used for inputting the identification code and the name of the electrical equipment and storing them in the storage module, and the input method may be key input, keyboard input, and the like.
