The above and other technical contents, features, and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments. Referring to FIG. 1 , FIG. 2 and FIG. 3 , a preferred embodiment of the power monitoring device 1 of the present invention is suitable for being coupled to a power line 94 of a user who uses a commercial power, and is used for a business unit that supplies a commercial power or a business that charges an electricity fee. The unit server 91 monitors the state of the commercial power supply on the power line 94 of the user terminal, and provides statistics on the amount of power used and information on the power consumption of the user, or even controls the power-off and power-off of the user terminal. The power monitoring device 1A includes a measurement unit π 11 coupled to the power line 94, a processing unit 12 electrically connected to the measurement unit u, and a storage unit 13 and a display unit 14 electrically connected to the processing unit 12, respectively. A timesheet 70 15 also has a wireless communication unit 16 for wireless transmission. Figure 2 shows the measurement unit! An internal circuit block diagram of i, including a current measuring module m coupled to the power line 94, and an analog/digital conversion module U3 (A/D) electrically connected to the processing unit 7G 12 Converter). In the present embodiment, the current measuring module (1) has a Hall element (not shown) that is loaded with a mains power line 94, which can be utilized to sense the magnetic flux density generated by the alternating current in the power line 94. Change, the phase produces a measurement corresponding to its alternating current, and outputs the measurement to the analog/digital conversion module 113, and the analog/digital conversion module ιΐ3 converts the measurement into a digital format. - The pen represents the measurement data of the current 201104997 flow on the power line %, and finally the measurement data is transmitted to the processing unit 12. In the present embodiment, the current value in the power line 94 is determined by sensing the change in the magnetic flux density caused by the current on the power line 94. This is merely an example, and the current meter may be connected in series to the power line 94. The embodiments and their corresponding drawings are limited. The timer unit 15 generates an interrupt signal to the processing unit 12 after a set period of time, so that the processing unit 12 determines the amount of current on the power line 94 received by the measuring unit 11 according to each time the interrupt signal is received. The measured data is substituted into "energy = power * time = (current * voltage) * time" to calculate an instantaneous power consumption data within the set time. In this embodiment, the time A is set to 1 millisecond, but the setting may be changed according to different requirements, which is not limited to the embodiment. In the present embodiment, the storage unit 13 is a user identity module that stores identity verification data specific to a specific user ((10) is like a SIM card). The identity verification data can be transmitted by the processing single A. The processing unit 12 is given. It should be noted that the storage unit 13 can also be replaced by other different types of memory, for example (-he, or other solid state disk uiStateDlsk) does not implement (four) Ph call, not to deal with the single A 12 will accumulate each The instantaneous calculated power consumption data becomes a power consumption data, and the disk data is integrated, and a identity verification unit 16 for the user terminal and the second storage vehicle 13 is transmitted by wireless transmission to fnfL ' In this embodiment, the wireless communication unit 16 is a communication unit of the Global System for Mobile Communications (GSM) standard, which can transmit the power consumption information of the user terminal to the base station 93 and transmit the information to the base station 93. The remote server 91, or even the handheld electronic device 92, is transmitted to the utility user to provide instant power usage information for the utility user. It should be noted that GSM is only one of the implementations of the wireless communication unit 16 of the present invention, and can also be replaced by a wireless communication unit of the PHS or GPRS standard, and is not limited to this embodiment. In this embodiment, the processing unit 12 transmits the power consumption information of the user terminal to the remote end through the wireless communication unit 16, and transmits the power consumption information of the user terminal to the display unit 14 (screen) electrically connected to the processing unit 12. The user of the power monitoring device 10 can also display the power consumption of the power monitoring device 10 by directly viewing the display unit 14 of the power monitoring device 10.

In this way, when the use or payment of the utility users is abnormal, the Lvye unit that supplies the mains can remotely remotely de-energize the user, and wait until the usage or payment situation returns to normal, and then remotely implement the re-powering measures. In summary, the effect of the present invention is that, according to the measurement data measured by the measurement unit ii and the identity verification data stored in the storage unit 13, the obtained user power consumption information can be wirelessly communicated. The unit 16 transmits the wireless transmission, and the server or even the user itself can immediately receive the power consumption information and count and count the bill, thereby saving manpower and time cost. The single 201104997 can also be used to directly power off or re-power the user. However, the above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the scope of the invention, that is, the simple scope of the patent scope and the description of the invention according to the present invention. Both effect changes and modifications are still within the scope of the invention patent.
