[0022] The OCS-based telephone alarm system adopts the spring cloud microservice technology architecture and is deployed based on Docker containers. It adopts the spring cloud microservice technology architecture and is deployed based on Docker containers. It separates the front-end display interface from the back-end business logic. All functions run in a unified container environment. Functional application service APIs are provided and published to the system's unified application service routing gateway. Functional application services implement unified scheduling and configuration, and deeply apply intelligent speech synthesis, semantic recognition and other technologies to optimize the telephone audio data of the alarm content, provide standard public service calls to the outside world, and provide unified support for the scheduling master station and various message sending and automatic telephone notification of key information to on-site operation and maintenance personnel or customers.

[0023] The hardware device uses an Ethernet interface, and there is no need to install a driver on the computer. When installing, you only need to connect the telephone line (or insert a SIM card), an Internet cable, and a power cord. It supports 10 channels (can be further expanded according to actual needs) for simultaneous outbound dialing and notifications, and supports one computer to control multiple devices. If you need to expand the capacity, you only need to add additional telephone voice equipment. The telephone voice equipment uses Leetel T400. The device supports at least 10 concurrent telephone channels and has basic functions such as telephone dialing and recording. It supports multiple VoIP packet data stream ports and analog telephone access; supports H.323 protocol group and SIP protocol; provides a high-level interface that encapsulates call processing and a low-level interface for RTP voice processing; supports various voice codec standards, such as G.723.1, G.711, G.729A / B, etc. The system can accurately and quickly identify the other party's off-hook and play the sound without being disturbed by the ringback tone. In some application scenarios, if it is necessary to accurately and quickly play the notification content after the other party picks up the phone, GSM / CDMA telephone voice equipment is used. Since GSM or CDMA is digital communication, it can accurately identify the other party's off-hook and on-hook through digital signaling, so it is not disturbed by the ringback tone. The voice equipment integration adopts TTS, which can be used to synthesize the notification voice in advance (reducing the workload of manual recording), or the notification content can be in text mode, and the voice can be synthesized and played in real time after the call is connected. The system supports customizing the time period for outbound calls, so as to avoid outbound calls in the middle of the night or during lunch breaks, which would interfere with the notification object; supports scheduled outbound calls, which can be made at the specified date and time; supports multiple notification modes to meet the needs of most scenarios: only delivery (notification of matters or business promotion), pressing the confirmation button to start playing (notification of veteran cadres), key feedback (questionnaires, meeting notifications), telephone collection of arrears and extraction of telephone numbers from the bid evaluation expert database, etc.; supports multiple voice management methods: computer microphone recording, outbound calls to other phones for recording, and TTS (text to speech); supports multiple condition combinations to query outbound call results, including date and time, task title, name, call results, feedback buttons, etc. The system can be connected to third-party software, and can provide database table structures. Third-party software sends table write records to the database through SQL statements, and the notification software AutoDialer can automatically read and dial the phone, and then save the notification results in the result table for third-party software to read.

[0024] The telephone alarm system includes an alarm information base, a smart phone call station and a public switching layer. The alarm information base inputs alarm information notification content and subscriber information to the smart phone call station, and the smart phone call station outputs a voice stream to the public switching layer to issue an alarm.

[0025] The alarm information library includes alarm classification subscription, alarm text access, API call, fault power outage notification, and dispatch notice access. An automatic telephone alarm rule library is established, and the automation operator can perform visual maintenance on the library. After configuring the rules for different types of services, the automatic telephone alarm can automatically receive alarm information, abnormal signals, business notifications and other data according to the configured telephone alarm rules, and then call the telephone call service of the intelligent telephone call station to automatically group dial the factory station duty phone and the relevant personnel phone within the authorized range; at the same time, the intelligent voice duty can automatically call the power grid customer service phone according to the authorization to notify the dispatch power outage equipment and the scope of the power outage. The automatic language alarm configuration content includes alarm type, alarm level, keyword, alarm time period, alarm priority, etc. The automatic telephone alarm can manually set the delay time, and the inherent delay time of the telephone alarm, that is, the delay between the time when the telephone alarm is issued and the time when the dispatch automation system issues the alarm should be within 2 seconds. Telephone alarm monitoring, according to the organizational division, realizes the classified monitoring of telephone alarms, and can view the content of completed and processed telephone alarms. The alarm information is encapsulated as a json object, and the encapsulated json object is published on the message bus. After the subscriber subscribes, the json object is parsed. According to the real-time alarm data and model data obtained from the pulsar message bus, semantic analysis technology is used to extract features to establish an alarm information knowledge base, and the knowledge base manual maintenance and management function is supported. According to the alarm information knowledge base, automatic alarm information is classified and managed according to the alarm level, alarm unit, alarm topic, etc., and the flag bit setting of alarm information telephone alarm and SMS alarm is realized to avoid duplication of voice broadcast and telephone alarm content, and reduce the pressure of telephone dialing times. The subscription configuration items include alarm content, alarm unit, alarm time, subscription period, subscriber and other elements. The alarm information subscription function is realized by filling in and saving the configuration items. The subscription mode includes two modes: group subscription and personal subscription. For the automated duty group, group subscription configuration can be performed. After the group subscription, the system automatically associates the information of each member of the automated duty group, and accurately pushes the subscription information according to the mobile phone number in the duty group personnel information, and records the push content and pusher information in the form of logs. Based on the SMS service interface provided by the OMS system, a unified SMS service is built, which is combined with classified subscription of alarm information to accurately push alarm information to dispatching personnel, operation and inspection personnel, customer managers and related management personnel, and an open API interface call service is provided to the outside world.

[0026] The smart phone call station includes speech synthesis service, voice call management, and voice exchange gateway. The speech synthesis service supports implementation through offline speech synthesis components to ensure its high availability. The speech synthesis service provides a standard interface to the outside world to support the needs of text-to-speech streams in different business scenarios; the voice call management includes call task management, phone number management, call task monitoring, call task statistics, call task scheduling, and external service call interface. These functional applications are implemented through secondary development based on the SDK provided by the voice exchange gateway, and all applications are easy to expand and deploy as separate microservices. Among them, the external service call interface encapsulates speech synthesis and voice call management as a service, and provides an automatic voice notification service interface. Each business application can pass parameters such as text notification content, notifier, recipient, and phone number, and the smart phone call station automatically completes the voice notification.

[0027] This module automatically obtains information related to the voice notification task, including text data, recipients, etc., through association with the intelligent voice duty and information classification subscription modules, and then automatically completes the phone call and voice notification; the voice exchange gateway includes analog and digital types or an analog-digital integration.

[0028] Dynamic scheduling mechanism: Dynamically generate a duty table for power dispatching automation operation according to the work responsibility area, adjustment date, duty rules, working days and other constraints of the power dispatching automation operation personnel. Through matching analysis between the duty table and the OCS alarm information, according to the dynamic scheduling information of the power dispatching automation operation personnel, the alarm will be automatically notified to the corresponding operation personnel by telephone voice during the alarm occurrence time period.

[0029] The public switching layer includes outbound calls and network outbound calls. One or more voice outbound call devices are added and set up, and outbound calls are made in turn using different channels. The automatic telephone alarm function automatically subscribes to alarm information from the real-time bus in the data interaction and integration function according to the information classification subscription result through integration with the data interaction and integration function, the information classification subscription function and the smart phone call station, and calls the service provided by the smart phone call station according to the telephone alarm parameters configured in this function module to complete the telephone alarm. The system can be set to add multiple time periods within a day when outbound calls are allowed. Outbound calls are allowed only when the current time is in one of the time periods. It is equipped with a complete monitoring interface, which can view the device type, status and signal strength of each channel. The concept of the waiting queue is designed. As long as there is a record of waiting to be called in the waiting queue, the system will automatically obtain the record and start the outbound call. The waiting queue has a visual interface, which can view the task information currently waiting for the outbound call, including the called person, number, playback content, call mode and number of calls. Importing call waiting data adopts importing a batch of numbers from Excel files into the call waiting queue or selecting a batch of specific contacts from the built-in phone book according to specified conditions into the call waiting queue or manually entering numbers. When importing outbound call notifications, you can select one of the four preset notification modes: just delivery, need to press key to confirm that you have listened, need to press key to feedback (questionnaire survey) and reminder of overdue fees; you can choose whether to schedule or not. The notification content is a pre-recorded voice file or a text in the hard disk (TTS function is optional). The system presets a directory for storing recording files, and sets a visual interface for managing recording files in this directory, including viewing and auditioning recording files, deleting and changing names. There are three ways to generate recording files: computer microphone recording, device outbound call recording, and TTS to convert text into recording. The system sets multiple conditions to query outbound call results: query by call date and time, called number, call result, feedback button and success or failure. For failed outbound calls, select and click a button to add it to the call waiting queue and restart. Statistics the total number of calls, successes, and failures within a time range, as well as the number of times each key is pressed.
