Wireless date module
The function of wireless data transmission module is connected to the Internet, send data from control through the antenna to the Internet, to forward the data from the Internet to the controller.This module contains an identity ID, when access to the Internet from wireless data module.This scheme, we adopt LXI680G wireless data module of the company.It across the GPRS network and the Internet, computer and serial port bridge equipment, solve the R232 serial port devices can only close connected to the computer problems.With GPS function, can locate RS232 serial port devices.Have messaging function, can at the same time of data transmission to send and receive messages.Especially suitable for the application of unattended.
LXI680G wireless data module is an industrial-strength, GPRS DTU with GPS global satellite positioning function, product.The product internal integration with high performance and low power consumption of industrial grade GPS module and GPRS module, GPS global positioning technology and wireless GPRS communication technology perfect combination of a product.
Wireless data module based on ARM platform, embedded operating system, the built-in industrial-grade module, it can be used in harsh environments, working temperature scope of application can be up to 40 ℃ ~ + 85 ℃.LXI680G provide standard RS232 serial interface, can be quickly and PLC, industrial control, instruments, meters, RTU equipment is linked together, will be linked to LXI680G equipment through GPRS network data transmission to a host on the Internet, realize the transparent data remote transmission, at the same time to the front-end equipment of GPS location information reported to host, achieve the positioning equipment.
Controller and LXI680G after binding, it is only through the password to unbundling, if forced unbundling, controller will record the alarm information or refused to start the next time the generator, this feature is especially suitable for generator rental industry. At the same time also the function of GPS satellite positioning, may at any time to know the location of the unit. Also can through the computer remote monitoring modify the configuration parameters of the thousands of miles away generating set, in order to more suitable for the field application.With as many as 150 black, can understand the operational parameters of generator in failure moment, include: voltage, current, active power, power factor, oil pressure, water temperature, rotational speed, and other important parameters.On LXI680G personalization, and integrate it in the existing equipment, the user can through the Internet and mobile phone tracking, monitoring, management of existing equipment.
The system core
It is the core part of the whole system, its role includes three aspects.
First, management all through wireless data module (DTU) Internet access controller.When wireless data module (DTU) access to the data center, it will inform the data center own identity ID, data center by the ID to distinguish different controllers.
Second, the management of all users to connect configuration software on a computer.Data center through the user name and password management to distinguish all users connected to the data center.When the user controller configuration software on your computer starts, it will automatically connected to the data center, and verified the login, the user can modify the default in the configuration software user name and password.Users are divided into two kinds, one kind is a common user, one kind is private users, two types of users have different data access.
Third, data transfer, management controller.Configuration software manages the wireless data module associated with the user ID list.Public users, data center at a certain moment only respond to such user interactions with the data of the controller;Private users, data center wireless data modules that are relevant to the user ID list synchronization to the data center, on a regular basis (time) can be set to scan they identify the working state of the generator, real-time alarm and tracking start-stop condition, tracking of oil change, coexist in the database, easy to query in the future.
Computer data center service, centralized management of all the controller connected to the Internet.It around the clock monitoring of generator rev. Stop, oil, oil pressure conditions, and record all kinds of alarm information.Users can start at any time on my computer configuration software to connect to the data center, to see all the current state of the generator, and receive real-time alarm information.
