Description

Technical Field

[0001] The invention relates to a method and a system for terminal accessing a main station, belonging to the field of terminal accessing a main station. Background Art

[0002] The 22 standard type I concentrator is an intelligent power consumption collection terminal that integrates the functions of power supply and consumption information collection in distribution stations, data collection of electric energy meters or collection terminals, equipment status monitoring and communication networking, local analysis and decision-making, collaborative computing, etc. The type III special transformer collection terminal is a new generation of special transformer control and management terminal designed based on the ARM core in accordance with the requirements of the State Grid Corporation of China to build a power user power consumption information collection system, combined with many years of research and development and field operation experience in the power industry. The type III special transformer terminal has functions such as AC sampling, state quantity collection, pulse quantity collection, and load control; it exchanges data with the electric energy meter through the downlink communication interface and completes data storage and processing functions; it uses the uplink communication interface to exchange data with the master station management system, and is mainly suitable for reading electric energy meter data for large industrial and commercial electricity users, monitoring the working conditions and power supply quality of electric energy metering equipment, and load control management. The energy controller is installed in the public or special transformer area, which can realize the flexible access of metering and sensing equipment on the customer side and the distribution side, and has functions such as data collection, intelligent fee control, clock synchronization, accurate metering, orderly charging, energy management, circuit status inspection, household-to-transformer relationship identification, and power outage event reporting. The above three terminals (hereinafter referred to as terminals) are of great significance for achieving the balance between the power supply capacity of the power grid and the energy demand of users, guiding users to use electricity at low valleys and discharge electricity at peak times, improving the ability of customers to deeply participate in power grid regulation, improving the operating efficiency of the power grid and the economic efficiency of users' electricity consumption, and promoting the green development of the country. 4G module refers to a device with a built-in 4G communication module, which can be used to realize functions such as mobile communication and data transmission. It can provide high-speed network connection for devices and is suitable for many application fields. 4G wireless communication module is a highly integrated hardware device. It is loaded with 4G communication module, supports standard LTE protocol, and can integrate wireless reception, transmission, baseband signal processing and other functions on the PCB board. At the same time, it is also equipped with various software functions, such as voice dialing, SMS sending and receiving, dial-up networking, etc., which can be widely used in terminal products such as security monitoring, smart metering, sharing economy, industrial interconnection, smart cities, and industry vertical applications. With the development of energy Internet, users in the power market have an increasing demand for smart applications of electric energy meters.

[0003] At present, there are two main steps in the process of launching the 4G module of the terminal. The first is to configure the terminal with the corresponding master station channel, which requires the master station communication software to cooperate with communication devices such as RS485 and RS232. The second is to adapt the 4G module to the protocol corresponding to the terminal, which requires the serial port tool and the dedicated protocol modification device of different module brands. In the above two processes, it is necessary to run the corresponding application (APP) on the host computer, connect the terminal to the corresponding device and then connect the device to the host computer, and configure the terminal 4G module with the corresponding protocol or establish a connection with the corresponding channel of the master station through the APP in the host computer. In this mode, the software developed by different module manufacturers for different terminals cannot be reused. Moreover, the terminal software and interfaces developed by different manufacturers cannot be standardized. Multiple corresponding software need to be installed in the host computer, so the software needs to be switched back and forth, which reduces the online speed of the terminal 4G module and increases the workload of users, resulting in a huge waste of software resources. Summary of the invention

[0004] The purpose of the present invention is to provide a method and system for terminal access to a main station, so as to solve the problem that the terminal accesses the main station slowly due to the inability to call the software designed by different manufacturers for the terminal 4G module when accessing the main station.

[0012] Figure 1 It is a schematic diagram of the software platform calling process of the present invention. DETAILED DESCRIPTION

[0013] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0014] The idea of ​​the present invention is to design a software platform integrated with a functional interface corresponding to the APP, and the corresponding functional interface of the software platform calls the corresponding APP, so as to achieve the purpose of configuring the corresponding protocol of the 4G module or configuring the main station channel.

[0015] Method Example: This embodiment provides a method for a terminal to access a main station. First, a software platform (dynamic function calling platform) combining multiple APPs is developed at the software level. The process of mutual calling between the platform and the APP is as follows: Figure 1As shown, the dynamic function calling platform in the figure runs in the upper computer, and the platform is used to call the corresponding APP with the corresponding function interface integrated to complete the terminal's 4G module configuration protocol and / or the terminal access to the corresponding communication channel of the main station. The dynamic function calling platform of the present invention is flexibly tailored according to system resources and operating environment, so as to support the 4G module configuration protocol and / or terminal access to the main station communication channel function. Based on convenience considerations, this embodiment uses the integration of all functional interfaces as an example to illustrate the process of the present invention. Integrating all functional interfaces refers to integrating the functional interfaces required by APPs developed by different manufacturers when configuring the 4G module protocol and when the terminal accesses the communication channel of the main station.

[0016] The present invention executes the 4G module configuration protocol process and / or the terminal access master station communication channel process according to the demand. Before the 4G module configuration protocol process is performed, an APP that can configure the 4G module to the desired protocol needs to be installed in the computer (for example, Figure 1 APP1 and APP2 in the master station); before the terminal accesses the master station communication channel, the computer needs to install an APP that can access the terminal to the corresponding master station communication channel (for example, Figure 1 APP3 and APP4 in it).

[0017] For the sake of convenience, in this embodiment, an APP that configures the 4G module to the corresponding protocol and an APP that connects the terminal to the main station communication channel are installed in the host computer. Since these APPs use different communication protocols when establishing connections with the platform, the communication protocols in the message bus must include the communication protocols required to establish communication connections with these APPs, such as IPC (Inter-Process Communication) protocol, TCP (Transmission Control Protocol), UDP (User Datagram Protocol) and MQTT (Message Queuing Telemetry Transport) protocol.

[0018] The process of configuring the corresponding protocol for the 4G module is as follows: the corresponding functional interface of the platform calls the corresponding protocol configuration application (for example, APP1) through the message bus (using UDP), and the protocol configuration program executes the corresponding process to configure the 4G module to the corresponding protocol (for example, MQTT).

[0019] The process of the terminal accessing the corresponding communication channel of the main station is as follows: the corresponding functional interface of the platform calls the corresponding channel configuration application (for example, APP3) through the message bus (using TCP), and the protocol configuration program executes the corresponding process to connect the terminal to the corresponding communication channel of the main station.

[0020] Since apps from different manufacturers are involved and for the reliability of communication, the platform conducts communication tests on the apps in turn, that is, tests the corresponding functional interfaces and the communication protocols used. After the tests pass, the platform then performs the process of configuring the 4G module with the corresponding protocol or the process of the terminal accessing the corresponding communication channel of the main station.

[0021] System Example: This embodiment provides a system for terminal access to a main station. The steps implemented by the computer-integrated application program, software platform, and computer program executed by the software platform in the system have been clearly introduced in the method embodiment, so they will not be repeated here.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents. Any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered within the scope of protection of the claims of the present invention.
