Description

Technical Field

[0001] This utility model relates to the field of power technology, and in particular to a remote monitoring system for automatic transfer switches. Background Technology

[0002] Currently, Automatic Transfer Switch (ATS) systems are widely used in power systems to automatically switch between main power and backup power sources to ensure the continuity of power supply.

[0003] Existing ATS systems typically rely on local Human Machine Interfaces (HMIs) for monitoring, which has several shortcomings. First, local HMIs can usually only monitor a single ATS device or a small-scale system, making it difficult to achieve centralized monitoring of multiple devices and sites. Therefore, in large power systems (such as data centers, hospitals, and industrial parks), it is difficult to have a comprehensive understanding of the operational status of all ATS devices. Second, local HMIs require on-site operation and cannot achieve remote monitoring and management. In the event of a main power failure, the real-time status of backup power switching cannot be fed back in a timely manner, potentially affecting the power supply continuity of critical loads. Maintenance personnel need to frequently visit the site to check equipment status, increasing labor and time costs, especially in remote or hazardous environments where costs and risks will increase significantly. Utility Model Content

[0004] Therefore, it is necessary to provide an automatic transfer switch remote monitoring system that can achieve remote centralized monitoring and management of multiple devices and sites at low cost and low risk.

[0008] The remote server includes a data parsing module, a data storage module, a data analysis module, an alarm processing module, and a data call API module. These modules are used to parse, analyze, and store the data transmitted from the acquisition device. When an abnormal state of the automatic transfer switch is detected, an alarm notification is sent and a data call API is provided.

[0015] Furthermore, the acquisition device also provides analog switch inputs.

[0016] Furthermore, the data acquisition device uses LoRa or NB-IoT low-power wide-area networks.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 This invention relates to an automatic transfer switch remote monitoring system, which adopts a four-layer architecture, including a device layer, a data acquisition layer, a platform layer, and a display layer. Specifically, it includes: a plurality of automatic transfer switches 10, a plurality of data acquisition devices 20, a remote server 30, and a plurality of display devices 40. The automatic transfer switches 10 are connected to the data acquisition devices 20 in a one-to-one correspondence, the data acquisition devices 20 are connected to the remote server 30, and the remote server 30 is connected to the display devices 40.

[0025] The automatic transfer switch 10 is used to automatically switch between the main power supply and the backup power supply, and the automatic transfer switch 10 provides two power supply states.

[0026] The data acquisition device 20 is used to acquire the power status of the automatic transfer switch 10 and upload it to the remote server 30.

[0027] The remote server 30 includes a data parsing module 31, a data storage module 32, a data analysis module 33, an alarm processing module 34, and a data call API module 35. The data parsing module 31, the data storage module 32, and the data analysis module 33 are used to parse, analyze, and store the data uploaded by the acquisition device 20, respectively. When an abnormal state of the automatic transfer switch 10 is detected, the alarm processing module 34 sends an alarm notification. The data call API module 35 provides a data call API (Application Programming Interface) for the display device 40.

[0028] The display device 40 includes terminal devices such as mobile phones and computers. The monitoring data of the automatic transfer switch 10 provided by the remote server 30 is presented to maintenance personnel or users through a mobile APP or computer web.

[0029] In this embodiment, preferably, each data acquisition device 20 has a unique serial number, which is displayed on the device in the form of a QR code. Device registration and identity verification are performed by scanning the QR code via a mobile app. In other embodiments, Bluetooth / NFC near-field communication can also be used to achieve rapid pairing and registration between the data acquisition device 20 and the mobile app. Furthermore, two-way certificate authentication (such as Transport Layer Security, TLS) can be used instead of serial number verification to further enhance communication security.

[0030] In this embodiment, preferably, the acquisition device 20 provides a digital input (DI) signal. In other embodiments, to support data acquisition from more types of ATS devices, an analog input (AI) signal or Modbus protocol communication can also be added.

[0031] In this embodiment, preferably, the data acquisition device 20 establishes a 4G wireless network and establishes a wireless communication connection with the remote server 30 through a built-in SIM card. In other embodiments, to adapt to scenarios without stable 4G wireless network coverage (such as remote areas), LoRa or NB-IoT low-power wide-area networks can also be used.

[0032] In this embodiment, preferably, the acquisition device 20 establishes a long-lived Transmission Control Protocol (TCP) connection with the remote server 30 via a socket for bidirectional communication. In other embodiments, to reduce network resource consumption and support reconnection after disconnection and message queuing, MessageQueuing Telemetry Transport (MQTT) communication can be used instead of the long-lived TCP connection.

[0033] In this embodiment, preferably, the acquisition device 20 is connected to the two power digital switch output channels of the automatic transfer switch 10 through the input channels of two digital switch (DI) signals, so as to detect the status of the automatic transfer switch 10.

[0034] In other embodiments, to reduce the load on the remote server 30, the acquisition device 20 also includes an edge computing module 21 for pre-analyzing data from the automatic transfer switch 10.

[0035] In other embodiments, the alarm processing module 34 of the remote server 30 can also push alarm information through multiple channels via third-party alarm platforms (such as WeChat Work, DingTalk, etc.). Furthermore, it supports tiered alarm strategies, such as using SMS for the first abnormal notification and triggering a phone notification for continued abnormalities.

[0036] The automatic transfer switch remote monitoring system of this embodiment performs monitoring tasks according to the following steps:

[0037] The data acquisition device 20 connects to the two power DI input signals of the ATS automatic transfer switch 10 through two DI input channels;

[0038] Register the data collection device 20 to the remote server 30 by scanning the QR code on the mobile app.

[0039] After the data acquisition device 20 is powered on, it establishes a long Socket TCP connection with the remote server 30, and reports a unique serial number to the remote server 30 every 2 seconds and packages and encrypts the ATS data for uploading.

[0040] The remote server 30 verifies the identity through the serial number, decrypts the verification code, parses the data and analyzes whether the data is abnormal. If an abnormality is found, it sends alarm notifications such as phone calls, text messages and emails to the relevant maintenance personnel preset by the device 40 through mobile APP or computer web terminal, and at the same time stores the parsed data in the database of the data storage module 32 of the remote server 30.

[0041] Applications on display devices 40, such as mobile apps or computer web applications, obtain data from the automatic switching switch 10 via the data API of the remote server 30 and display it visually to maintenance personnel or users.

[0042] In other embodiments, to support data acquisition from more types of ATS devices, analog input (AI) signals or Modbus protocol communication can be added. To adapt to scenarios without stable 4G wireless network coverage (such as remote areas), LoRa or NB-IoT low-power wide-area networks can also be used. Identity registration and verification steps can also be achieved through Bluetooth / NFC near-field communication for rapid pairing and registration between the acquisition device 20 and the mobile app. Furthermore, two-way certificate authentication (such as Transport Layer Security, TLS) can be used instead of serial number verification to further enhance communication security. To reduce network resource consumption and support reconnection after disconnection and message queuing, Message Queuing Telemetry Transport (MQTT) communication can be used instead of TCP long connections. To reduce the load on the remote server 30, the acquisition device 20 also includes an edge computing module 21 for pre-analyzing data from the automatic transfer switch 10. The alarm processing module 34 of the remote server 30 can also push alarm information through multiple channels via third-party alarm platforms (such as WeChat Work, DingTalk, etc.). In addition, it supports tiered alerting strategies, such as sending an SMS notification for the first abnormality and triggering a phone notification for continued abnormalities.

[0043] This embodiment of an automatic transfer switch remote monitoring system enables second-level (<2s) data acquisition and transmission via wireless network, supports centralized monitoring of multiple sites, reduces the frequency of on-site inspections by maintenance personnel, and achieves real-time, remote, and multi-site monitoring. Its four-layer hierarchical architecture allows flexible access to automatic transfer switches from different brands and supports future functional module expansion, such as energy efficiency analysis, demonstrating high compatibility and scalability. Data encryption and authentication mechanisms prevent tampering and unauthorized access, while TCP long connections / retransmission ensure communication stability. Remote alarms and visualization analysis via mobile app or computer web reduce labor costs, and rapid anomaly response minimizes power outage losses. It is particularly suitable for high-risk / remote scenarios, offering cost reduction and efficiency improvement benefits.

[0044] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
