Embodiment Construction

[0026] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] Such as figure 1 and figure 2 As shown, the device for timing the meter based on GPS technology includes a GPS receiving module, an MCU module, and a broadcast communication module. The text is decoded to make the internal clock consistent with the current time. When the time reaches the set value, the control signal is sent to the broadcast communication module through the MCU module, and the broadcast communication module is driven to perform time service to the electric meter in the electric meter box. The above-mentioned broadcast communication module includes a plurality of infrared LEDs, and the plurality of infrared LEDs are respectively arranged in various directions of the device.

[0028] During actual work, the MCU module regularly sends a query command to the GPS receiving module to correct the time once to ...

Abstract

The invention relates to a method and a device for carrying out calibration and timing of an electric meter, in particular to the method which carries out the timing of the electric meter on the basis of the GPS technology and the device thereof. The method which carries out the timing of the electric meter on the basis of the GPS technology comprises the following steps of: a. using the GPS to obtain the current time information; b. calibrating the current time at the definite time; c. carrying out the timing of the electric meter by a broadcast communication mode. The invention further discloses the device for carrying out the timing of the electric meter on the basis of the GPS technology, comprising a GPS receiving module, an MCU module and a broadcast communication module. The method and the device can ensure the accuracy of a clock of the electric meter and prevent the time and the date from being forged and modified illegally. At the same time, the method and the device are characterized by simple structure, convenient implementation and low cost.

Description

technical field [0001] The invention relates to a method and a device for timing the electric meter, in particular to a method and a device for timing the electric meter based on GPS technology. Background technique [0002] At present, the peak and valley electricity segmental pricing is generally implemented in residential electricity consumption. To ensure the accuracy of electricity metering, it is necessary to ensure the clock accuracy of the multi-rate meter used for metering within the service life time range, and the meter is based on the internal clock of the crystal oscillator. The accuracy is not enough, so it must be calibrated periodically. The current calibration method of the electric meter clock is as follows: assign a special person to arrive at the installation site of the electric meter box, and use an infrared meter reading device to correct the electric meter clock one by one. But this method has the following problems: [0003] (1) The number of elect...
