[0014] In view of the deficiencies of the prior art, the solution idea of the utility model is that no fixed display, test port, key and other man-machine interaction devices are arranged in the circuit breaker, but one communication port is directly communicated with the upper computer, the communication configuration parameters of the communication port are adjusted through a selection switch, and the communication connection problem of the circuit breaker with the upper computer under the condition that the communication parameters of the circuit breaker are unknown can be solved by combining an independent display unit.
[0015] The technical scheme proposed by the utility model is as follows:
[0016] A circuit breaker comprises a controller and a separate display unit; the controller has a communication port and a selection switch, and a set of fixed default communication parameters and a set of settable set communication parameters are stored in the controller, and the selection switch is used to select one of the default communication parameters and the set communication parameters as the communication configuration parameter of the communication port; the display unit has a first communication port using the default communication parameters as the communication configuration parameter, and the display unit is configured to extract the set communication parameters in the controller for display when the first communication port is in communication connection with the communication port of the controller.
[0017] With the above scheme, in normal cases, the set communication parameters are selected by the selection switch as the current communication configuration parameter of the communication port (which can be called standard mode), and then the communication port is connected with the communication port of the upper computer, so as to realize the communication connection between the upper computer and the circuit breaker, and the upper computer can read the measurement parameters and protection parameters of the circuit breaker, and the protection parameters of the circuit breaker can be adjusted through the upper computer.
[0018] If the user forgets or does not record the current set communication parameters due to installation, debugging or other reasons, resulting in that the upper computer cannot communicate with the circuit breaker, at this time, the default communication parameters can be selected by the selection switch as the current communication configuration parameter of the communication port (which can be called expansion mode), and the communication port is connected with the first communication port of the display unit, and since the two communication ports use the default communication parameters, the display unit and the circuit breaker can realize normal communication, the current set communication parameters of the circuit breaker read and displayed by the display unit are recorded, the selection switch is adjusted back to the standard mode, and the communication port of the upper computer is connected with the communication port of the controller of the circuit breaker, and the communication port of the upper computer is configured according to the recorded set communication parameters, so as to realize the communication connection between the upper computer and the circuit breaker.
[0019] The following further improved technical solutions can also be used:
[0020] The display unit further comprises a second communication port, and the display unit is configured to use the extracted set communication parameters as the communication configuration parameter of the second communication port when the first communication port is in communication connection with the communication port of the controller.
[0021] This further improved technical solution allows for communication between the host computer and the circuit breaker in standard mode when communication is impossible. The selector switch is then switched to extended mode, and the first communication port of the display unit is connected to the communication port of the circuit breaker controller. The second communication port of the display unit is then connected to the communication port of the host computer. The host computer's communication port is configured according to the current communication parameters of the circuit breaker displayed on the display unit. At this point, the host computer can communicate normally with the circuit breaker controller through the display unit. After completing the required communication, the display unit can be removed, the communication port of the host computer can be connected to the communication port of the circuit breaker controller, and the selector switch can be switched back to standard mode, thus enabling direct communication between the host computer and the circuit breaker in standard mode.

[0026] If, due to installation, debugging, or other reasons, the user forgets or fails to record the current communication settings, resulting in the inability of the host computer and the circuit breaker to communicate, then the following can be done: Figure 2 As shown, the communication port 1 of the display unit is connected to the communication port of the circuit breaker, and the selector switch is set to extended mode. The circuit breaker controller configures the communication port using default communication parameters. Since both the communication port 1 of the display unit and the communication port of the circuit breaker use default communication parameters, normal communication can be achieved between the display unit and the circuit breaker. The current setting communication parameters of the circuit breaker read and displayed by the display unit are recorded, and then...

At this time, the display unit extracts and displays the current setting communication parameter of the circuit breaker controller, and configures the communication port 2 according to the setting communication parameter. The communication port of the host computer is configured according to the current setting communication parameter of the circuit breaker displayed by the display unit. At this time, the host computer can normally communicate with the circuit breaker controller through the display unit. After the current required communication is completed, the display unit can be removed, and the communication port of the host computer is connected with the communication port of the circuit breaker controller according to Figure 1 As shown, the selection switch is adjusted to the extension mode, and the communication port 1 of the display unit is connected with the communication port of the circuit breaker controller, and the communication port 2 of the display unit is connected with the communication port of the host computer.
