Description

{Power measuring system}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power measuring system, and more particularly, to a power measuring system that can easily prevent a user from operating erroneously when checking the state of a measuring device.

In general, the monitoring device monitored the Local operation mode and the Remote operation mode status of the measurement device via remote communication such as RS-485 communication or Ethernet communication.

Here, when the operation mode of the measurement device is the local operation mode, the monitoring device can directly operate the input module disposed in the measurement device to operate the information of the breaker and the information of the initially set data, In the remote operation mode, the control information of the circuit breaker and the information of the initial set data can be manipulated through the remote device connected to the network.

However, when the user or the inspector checking the state of the measuring device changes or sets the information of the control information and the initial set data of the circuit breaker due to a wrong operation of the input module or the remote device while checking the state of the measuring device, An abnormal operation such as a trip may occur.

In recent years, studies are underway to prevent the control information of the circuit breaker and the information of the initially set data from being changed or set due to the erroneous operation that may occur when checking the state of the measuring device, as described above.

An object of the present invention is to provide a power measuring system which is easy to prevent user misoperation when checking the state of a measuring device.

The power measuring system according to the present invention is characterized in that when the measurement device storing the setting information including the control information of the circuit breaker and the initially set data information and the measurement device are present in the set state check list, And a monitoring device for transmitting setting lock information for locking the operation mode set in the device to the measuring device.

Wherein the measuring device inputs operation mode information for the operation mode of either a local operation mode or a remote operation mode, and inputs, when the local operation mode is input, A communication module for communicating with the remote device so as to change or set the setting information from a remote device connected to the network upon inputting the operation mode information for the remote operation mode; And a control module for controlling the input module and the communication module and controlling the change or setting of the setting information according to the setting lock information when the setting lock information is inputted from the monitoring device.

The communication module may perform RS-485 communication or Ethernet communication with the remote device, perform communication with the monitoring device, and perform communication with the remote device under the control of the control module.
