Description

Technical Field

[0001] The utility model relates to the technical field of production process control, in particular to a power failure alarm device. Background Art

[0002] The 24V power supply is a crucial component in equipment control, and certain key areas are equipped with redundant power supplies to ensure the safety of control equipment. As power supplies age, the potential risk of failure increases. However, for an uninterrupted production line, equipment control issues during the production process are unacceptable. To ensure that a single power supply failure in each redundant power supply group can be promptly detected and addressed, maximizing the redundancy and safety of the redundant power supplies, a power failure alarm device has been added to the existing system. This provides real-time monitoring and alarming of the power status of production line control equipment, enabling prompt detection and resolution of power failures, ensuring uninterrupted production.

[0003] Since the control equipment of the substrate glass production line uses a large number of 24V power supplies and is dispersed across many areas, after a power failure occurs, the search and treatment of the faulty power supply is often delayed, which will have a serious impact on the control of the production line equipment and process production. Utility Model Content

[0004] The purpose of the present invention is to provide a power failure alarm device to solve the technical problem that the search and treatment of faulty power supplies are often delayed, which has a serious impact on the control of production line equipment and process production.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A power failure alarm device includes a power supply, a switch, a fuse, a relay, a DCS controller, a voice alarm and a loudspeaker; the output end of the power supply is connected to the switch, the switch is connected to one end of the fuse, the other end of the fuse is connected to the power connection terminal of the relay, one relay contact of the relay is connected to the DI end of the DCS controller, the DO end of the DCS controller is connected to the voice alarm, and the voice alarm is connected to the on-site loudspeaker.

[0007] As a further solution of the present invention: the ON / OFF state of the relay contact corresponds to the normal / fault state of the power supply.

[0008] As a further solution of the present invention: the DI terminal of the DCS controller is connected to a plurality of power failure monitoring and alarm wirings.

[0010] As a further solution of the present invention: the DCS controller is connected to a monitoring camera, and the monitoring camera is connected to a remote display screen via wireless communication.

[0011] Beneficial effects of the utility model:

[0012] (1) The utility model realizes the safety monitoring of important power supplies in the control of substrate glass production line equipment, and can promptly send an alarm voice of the corresponding power supply to on-site personnel after a power failure occurs. On-site staff can quickly lock the location of the faulty power supply according to the corresponding alarm voice, so as to quickly handle power failure accidents, reduce the impact of equipment control on process production, and effectively ensure the redundancy integrity of redundant power supplies.

[0013] (2) In the DCS control system, the monitoring and alarm wiring of multiple power supply failures can be centralized into the DI terminal of the DCS.

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-2As shown, the utility model is a power failure alarm device, comprising a power supply 1, a switch 2, a fuse 3, a relay 4, a DCS controller 7, a voice alarm 8 and a speaker 9; the output end of the power supply 1 is connected to the switch 2, the switch 2 is connected to one end of the fuse 3, the other end of the fuse 3 is connected to the power connection terminal of the relay 4, a relay contact 5 of the relay 4 is connected to the DI end 6 of the DCS controller 7, the DO end of the DCS controller 7 is connected to the voice alarm 8, and the voice alarm 8 is connected to the on-site speaker 9. The power failure alarm device will only work after the switch 2 and the fuse 3 are closed.

[0021] The ON / OFF state of the relay contact 5 corresponds to the normal / fault state of the power supply 1 .

[0022] It should be noted that when power supply 1 outputs normally, relay 4 activates, relay contact 5 is in the ON state, and DCS controller 7 receives the ON signal. The system determines that power supply 1 is normal, and no power failure alarm voice is output. When power supply 1 outputs abnormally or is absent, relay 4 does not activate, relay contact 5 is in the OFF state, and DCS controller 7 receives the OFF signal. The system determines that power supply 1 is abnormal, and the system outputs the corresponding power failure alarm voice.

[0023] In an optional embodiment, the DCS controller 7 records the normal / fault status of the power supply 1 in real time.

[0024] In the DCS controller 7, the contact signal of the relay 4 is recorded and stored in real time through program configuration. When the relay contact 5 is in the OFF state, the system continuously triggers the voice output of the alarm module until the relay contact 5 stops triggering the alarm in the ON state, thereby realizing the monitoring and alarm of the power supply status.

[0025] The DI terminal 6 of the DCS controller 7 is connected to the fault monitoring and alarm wiring of multiple power supplies 1.

[0026] It should be noted that by utilizing the alarm device and method for a single power supply failure, the fault monitoring and alarm wiring of multiple dispersed power supplies 1 are integrated into the controller DI terminal 6. The DCS configures the status judgment program for multiple power supplies to realize the fault alarm of multiple corresponding power supplies. When multiple power supplies fail at the same time, the DCS controller 7 outputs the corresponding multiple alarm voices in a cyclic manner.

[0027] The DCS controller 7 is connected to the remote display screen via wireless communication.

[0028] It should be noted that when a power failure alarm is issued, the remote display screen will display the alarm information in real time.

[0029] The DCS controller 7 is connected to a monitoring camera, which is connected to a remote display screen via wireless communication.

[0030] It should be noted that by connecting the monitoring camera, when the DCS controller 7 detects that the power supply 1 is abnormal, the corresponding camera is started to shoot the power supply 1 and upload it to the remote display screen. The DCS system power alarm screen corresponds to the status of each actual power supply. When the power supply fails, the DCS system screen will actively pop up the alarm screen of the corresponding power supply, and the power supply alarm light installed on site will flash.

[0031] The working principle of the utility model is as follows: When the power supply 1 output is normal, the relay 4 is activated, the relay contact 5 is in the ON state, the DCS controller 7 receives the ON signal, the system determines that the power supply 1 is normal, and the corresponding fault alarm voice is not output. When the power supply 1 output is abnormal or there is no output, the relay 4 does not operate, the relay contact 5 is in the OFF state, the DCS controller 7 receives the OFF signal, the system determines that the power supply is abnormal, and the corresponding power supply fault alarm voice is output.

[0032] In the DCS system, through program configuration, the signal of the relay contact 5 of the relay 4 is recorded and stored in real time, and the voice output of the voice alarm 8 is continuously triggered in the OFF state until the alarm triggering stops in the ON state, thereby realizing the monitoring and alarm of the power supply 1 status.

[0033] The utility model adopts a combination of hardware and software, takes the output voltage of the on-site 24V power supply as the power supply of the relay 4, and sends the signal of the relay contact 5 to the DI terminal 6 of the DCS controller 7. The normal / fault state of the 24V power supply is judged by the ON / OFF signal of the controller DI terminal 6. The DCS system outputs the signal representing the normal / fault state to the voice alarm 8 through the DO terminal, thereby triggering the alarm voice of the corresponding power supply in the voice alarm 8 and transmitting it to the on-site personnel through the on-site loudspeaker, thereby realizing remote and timely alarm and processing of the on-site power supply.

[0034] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
