Description

Technical Field

[0001] The utility model belongs to the field of UPS power supply, and specifically relates to a UPS remote monitoring system. Background Art

[0002] A UPS (Uninterruptible Power Supply) is an uninterruptible power supply (UPS) that includes an energy storage device. It's primarily used to provide uninterruptible power to devices requiring high power stability. When the mains power input is normal, the UPS stabilizes the mains voltage and supplies it to the load. In this case, the UPS acts as an AC voltage regulator, while also charging the internal battery. When the mains power is interrupted (caused by a power outage), the UPS immediately converts the battery's DC power to 220V AC power via an inverter, allowing the load to continue operating normally and protecting its software and hardware from damage. UPS devices typically provide protection against both overvoltage and undervoltage conditions.

[0003] The comparative document (CN118316177A) discloses a UPS uninterruptible power supply, which relates to the technical field of UPS power supply, including an outer shell and a cover, a storage plate is slidably connected to the lower part of the inner cavity of the outer shell, a UPS power supply is placed on the upper surface of the storage plate, a filling cavity is left between the lower end surface of the storage plate and the bottom plate of the outer shell, the filling cavity includes an upper activated carbon adsorption layer and a lower pearl cotton pad layer, alarm indicators are installed on the four sides of the outer shell, a tipping sensor is installed in the storage plate; a protrusion is provided at the center of the bottom of the storage plate; the tipping sensor includes an arc-shaped sensing cavity, external contacts are fixed at both ends of the sensing cavity, a sliding rod is fixed between the external contacts, a connecting column is fixed in the middle of the sliding rod, and a slider contact is slidably sleeved on the sliding rod at both ends of the connecting column; the UPS power supply can more reliably maintain a stable state when subjected to bumps, and is not prone to damage to components. At the same time, it can provide a more stable alarm when tipping.

[0004] However, the above-mentioned comparative documents lack effective monitoring of the UPS power supply status, especially remote monitoring. When the UPS uninterruptible power supply fails, it cannot be monitored in real time. For example, when the mains power disappears, the UPS uninterruptible power supply cannot switch to battery power supply mode, resulting in no AC220V voltage output, power outage of important equipment, and immeasurable losses. For power plants, it will cause some important protection functions to fail, affecting the safe operation of the unit. Utility Model Content

[0016] The following is a detailed description of the specific embodiments of the present invention by referring to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution of the present invention and to facilitate its implementation. To make the technical solution of the present invention more clear, the present invention is explained through the following embodiments.

[0017] A UPS remote monitoring system, such as Figure 1 As shown, the system includes a UPS status detection device, a signal receiving device, a controller, and an alarm device, wherein the UPS status detection device is installed on the UPS, the output end of the UPS status detection device is connected to the input end of the signal receiving device, and the UPS status detection device is used to obtain the status information of the UPS to detect abnormalities; the output end of the signal receiving device is connected to the input end of the controller, and the signal receiving device is used to collect the status information of the UPS and convert it into a digital signal and then send it to the controller; the output end of the controller is connected to the input end of the alarm device, and the controller is used to receive and process the UPS status information uploaded by the signal receiving device, and when an abnormal UPS status is detected, it sends an abnormal alarm signal to the alarm device; the alarm device is used to notify the staff to handle the abnormal alarm signal after receiving the abnormal alarm signal. It should be noted that in this embodiment, the connection between the components includes both wired connections realized by auxiliary materials such as terminals and cables, and wireless communication connections.

[0018] Specifically, the UPS status detection device of this embodiment includes an AS400 dry contact card. The output contacts of the AS400 dry contact card are contact-type and are initially in a normally open or normally closed state. Figure 2 As shown, the contact output contacts of the AS400 dry contact card in this embodiment include a UPS fault contact, an error alarm contact, a ground contact, an unused contact, a common contact, a bypass status contact, a low battery voltage contact, an inverter status contact, and a mains fault contact. The open and closed status of each contact output contact reflects the current operating status of the UPS. When a UPS anomaly occurs, the status of each contact output contact will change accordingly, for example, from open to closed or from closed to open. The corresponding contact status signal will be sent to the signal receiving device. The change in the contact status signal can accurately identify the UPS fault location, facilitating subsequent maintenance.

[0019] The signal receiving device of this embodiment includes a switch input card component, the input end of the switch input card component is connected to the output end of the UPS status detection device, and the output end of the switch input card component is connected to the input end of the controller. In this embodiment, since the outputs of the AS400 dry contact card are all switch quantities, this embodiment adopts a switch input card component as a signal receiving device, and the switch input card component is used to collect the status signal of the UPS status detection device, that is, the contact status signal (switch quantity) output by the AS400 dry contact card, and convert it into a digital signal and send it to the controller. The switch input card component has the advantages of fast and accurate signal recognition and high reliability, thereby ensuring the real-time and stability of the remote monitoring of the system of this application. Preferably, the model of the switch input card component is KM234A or DI16, which can be flexibly selected according to the actual scenario.

[0020] The controller of this embodiment adopts a DCS system (distributed control system). The input end of the DCS system is connected to the signal receiving device, and the output end of the DCS system is connected to the alarm device. The DCS system is used to receive and process the UPS status information uploaded by the signal receiving device, and send an abnormal alarm signal to the alarm device when an abnormal UPS status is detected. DCS systems are widely used in various industrial scenarios, such as power plants. Based on the DCS system, when performing UPS remote monitoring, the present application only needs to plug in and set the corresponding DCS signal input card to realize the input of the UPS status signal. At this time, the data processing capability of the DCS system can be used to realize remote UPS status monitoring, which reduces costs and has a wide range of application scenarios.

[0021] The alarm device of this embodiment includes a signal light and a buzzer, each connected to the controller, for providing visual and audible warnings upon receiving an abnormality alarm signal from the controller. When an abnormality alarm signal is issued, the alarm device promptly alerts personnel to take action, preventing the UPS from being unable to switch to battery power after the mains power is lost, resulting in a loss of AC220V output and a power outage for critical equipment. For example, in a power plant, this could cause the failure of some important protective functions and affect the safe operation of the units.

[0022] Preferably, the system of this embodiment further includes a display, connected to the controller, for displaying UPS status information collected by the UPS status detection device. The display can be a computer, smartphone, tablet, or other display device. In this embodiment, when the DCS system detects an abnormal UPS status from the contact status signal, the display can display different colors to indicate the UPS status, such as red indicating an abnormal operation alarm and green indicating normal operation. In this embodiment, the use of the display allows staff to more intuitively monitor UPS status. Furthermore, by displaying changes in the status signals of the output contacts of each AS400 dry contact card, specific UPS faults can be located.

[0023] The UPS remote monitoring system provided in this embodiment can remotely monitor the operating status of the UPS. When an abnormal alarm occurs during operation, it can promptly prompt the staff to handle it in advance to avoid the lack of AC220V voltage output after the mains power is lost.

[0024] The above description of the present invention is provided as an example, in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described method. Any non-substantial improvements made using the method concepts and technical solutions of the present invention, or any application of the above-described concepts and technical solutions of the present invention to other situations without modification, are all within the scope of protection of the present invention.
