Problems solved by technology
Some products can display the network connection, but the existing intelligent switch uses the blinking state of the LED light to show the network connection. More information needs to add LED lights, which not only increases the cost, but also may not be able to realize the requirement of displaying more information due to the limitation of the product shape, and the types of network status that can be indicated are limited
If a product containing a specific number of LED lights is customized according to individual needs, not only is the product bulky, the cost is high, and it cannot meet the needs of industrialized mass production

The invention relates to a device for monitoring a network connection state of a smart grid. The device comprises a display screen, an input device, a network connection circuit and a microprocessor, wherein the microprocessor determines the network connection state, the display screen is connected with the microprocessor and is used for displaying the network connection state determined by the microprocessor, the network connection state displayed by the display screen includes types of normality in network connection and failure in network connection, and when the microprocessor judges that no main device exists on the network of the smart grid, the network connection circuit is used for simulating the main device to transmit a test signal for detecting the network connection to an electronic-type controller. Due to the adoption of the device for monitoring the network connection state of the smart grid, the communication connection state monitoring problem and the detection efficiency problem of the smart grid when in an installation and debugging period and in a normal working period can be solved.
Description
technical field [0001] The invention relates to equipment for monitoring the network connection status of the smart grid, in particular to a test module for testing the network connection status of the smart grid and an electronic controller capable of graphically displaying the network connection status. Background technique [0002] The basis of building a smart grid is intelligent low-voltage electrical appliances with network communication functions, such as circuit breakers, overload relays, contactors, leakage protectors and other intelligent switches. The core components of intelligent low-voltage electrical appliances are microprocessor-based and Electronic controllers or trip units with network interfaces, most of the smart controllers use building block matching solutions, which can be directly installed in the body of smart switching devices (such as circuit breakers). [0003] When building a smart grid, a network protocol that follows the "master-slave" principl...
