a controlling module is provided at the circuit board, and the controlling module is electrically connected to the alarming device; and
the controlling module is configured for controlling the alarming device to perform an alarming operation, wherein the alarming operation enables an operator to locate a room corresponding to the electronic door plate;
wherein the alarming device comprises: at least one of a sound alarming device and a lamplight alarming device;
wherein the lamplight alarming device is fixed to a side wall of the center frame;
wherein the lamplight alarming device comprises: a light bar and a light-bar cover plate;
the light bar is fixed to the side wall of the center frame, and is electrically connected to the controlling module; and
the light-bar cover plate covers the light bar;
wherein a slot is provided on one side of the light-bar cover plate that is closer to the light bar, and a diffusing soft-rubber structure is embedded in the slot;
wherein a flanging part is provided on one side of the diffusing soft-rubber structure that is closer to the light bar, and the flanging part protrudes out of the slot.

2. The electronic door plate according to claim 1 , wherein the diffusing soft-rubber structure is made from a polyvinyl chloride, a polyamide elastomer, a polyolefin elastomer or a polyurethane elastomer each of which is added a light diffusant.

3. The electronic door plate according to claim 1 , wherein the light-bar cover plate is a transparent light-bar cover plate.

4. The electronic door plate according to claim 1 , wherein the back cover is provided with a through hole at a position corresponding to the lamplight alarming device, and the light-bar cover plate is embedded in the through hole.

5. The electronic door plate according to claim 1 , wherein the sound alarming device is a buzzer.

6. The electronic door plate according to claim 1 , wherein the electronic door plate further comprises: a cover plate, and the cover plate covers the display screen, and is fixedly connected to the center frame.

7. The electronic door plate according to claim 1 , wherein the electronic door plate further comprises: a communication module, and the communication module is configured for being wirelessly connected to a target device, and receiving an operating instruction sent by the target device; and
the controlling module is electrically connected to the communication module, and the controlling module is configured for, in response to the operating instruction sent by the target device and received by the communication module, controlling the alarming device to perform an alarming operation.

8. The electronic door plate according to claim 1 , wherein the electronic door plate further comprises: a manipulating button, and the manipulating button is configured for receiving an operating instruction of a user; and
the controlling module is electrically connected to the manipulating button, and the controlling module is configured for, in response to the operating instruction of the user received by the manipulating button, controlling the alarming device to perform an alarming operation.

9. The electronic door plate according to claim 1 , wherein the display screen is an electronic-paper display screen.

10. The electronic door plate according to claim 1 , wherein at least one of a light color and a flicker frequency of the lamplight alarming device corresponds to a type of an operating instruction of an operator.

11. The electronic door plate according to claim 1 , wherein the light bar is provided with one elongate light emitting source, or is provided with a plurality of granular light emitting sources.

12. The electronic door plate according to claim 1 , wherein the light-bar cover plate is provided with a blocking flange at a position corresponding to the flanging part, and the blocking flange clings to and is connected to the flanging part.

13. The electronic door plate according to claim 5 , wherein the back cover is provided with a sound emitting hole at a position corresponding to the buzzer.

14. The electronic door plate according to claim 1 , wherein the controlling module is a chip or controlling circuit provided at the circuit board.

15. A system for managing an electronic door plate, wherein the system comprises: a calling machine, an upper computer and the electronic door plate according to claim 1 ; and the electronic door plate, the calling machine and the upper computer are wirelessly connected.
