Outline requirements
With the development of modern enterprise management improvement and efficiency improvement requirements, it is necessary to accurately and real-time monitor the operation status of large-scale equipment and facilities, formulate and execute accurate maintenance and inspection plans; collect real-time energy consumption data of equipment and facilities; ensure that Equipment safety, control and reduce maintenance costs. Based on more than 5 years of experience in the development and implementation of electronic counting and wireless meter reading systems, and combined with GPS, GPRS, GIS and other technologies, Dunn Technology has launched a “remote wireless meter reading and equipment monitoring system”, which provides comprehensive solutions to the above problems. s solution.
The system provides an interface for data acquisition by dialogue with CNC equipment PLC. Through this interface system can read equipment operating conditions, electrical parameters and other data, and store them in databases such as Access, SQL or Oracle; with advanced manufacturing management at home and abroad Based on the concept, combined with the special calculation, analysis and statistical methods that come with the system, a variety of reports and charts are used to intuitively reflect the current or past equipment operating conditions for a certain period of time, helping equipment managers to make scientific and effective decisions through feedback information .
system structure
Install the integrated controller in the cab of the mechanical equipment to collect the location information and operating status of the equipment. The data is transmitted to the monitoring center through GPRS or WIFI and other networks. The monitoring center can be set up inside the enterprise to provide remote monitoring and management of the enterprise’s own equipment; the monitoring center can also be located at the manufacturer, and the manufacturer can perform operation monitoring, after-sales service and maintenance reminders on the equipment sold.
The equipment monitoring center is equipped with a monitoring management platform to store equipment data and run equipment monitoring and management software; through the B/S structure of the client to provide equipment monitoring services to managers, they can browse the equipment’s real-time data, operation history, fault conditions and network conditions, etc. . The system supports Web access for multiple terminals.
System functions
Device location and tracking
Integration with Google Maps can display device location information in real time (or location based on other GIS). Track the running line of the device, store the location information of the target device, and can play back and print the track.
Equipment status collection
Collect the equipment’s geographic location, exercise information, energy consumption data, working status, operating parameters, fault information, etc.
Device data return
Provide multiple ways of remote meter reading, such as GPRS, WIFI, etc. The meter reading time can be set (every day or hour, etc.). The meter can also be read through a handheld PDA, and the electronic meter can be configured remotely through the PDA.
WEB access
Users can access the device to monitor the WEB server through a desktop computer, notebook, PDA or mobile phone. The monitoring management platform (B/S structure) is for managers to browse controller data and set field network equipment parameters.
Alarm function
The system provides fault alarms, real-time alarms, can define alarm conditions, and supports multiple alarm methods such as local interface alarms, SMS alarms, and email alarms.
Data storage and analysis
The database stores real-time operating data of equipment and facilities, and analyzes the law of data development. Generate all kinds of analysis and reports to provide management decision-making.
Support other systems
The system provides standardized data service interfaces and communication protocol access interfaces, which can be connected to systems such as EAM or ERP.
Performance characteristics
The service client supports the access of thousands of devices
It can manage the access of more than 1000 devices, and can realize more mechanical equipment access to the monitoring system through upgrade and expansion.
Multiple network networking to overcome geographic barriers and ensure smooth communication
The system can provide intelligent terminal products that support a variety of communication network forms, ensuring that widely distributed devices use multiple networks to complete remote communication. Supported network types: optical fiber, dedicated line, ADSL, GPRS, CDMA, 3G and other networks.
Support unified access of multiple devices of different brands and different communication protocols
The software platform supports the access of multiple industrial controllers, supports the analysis of multiple industrial communication protocols (such as Modbus, Hostlink, PPC, etc.), and can also provide users with customized development of special protocols.
Multi-channel and multi-type signal acquisition
The system has a total of 10 acquisition channels, which can acquire 10 signals at the same time; the signal forms are diversified and support multi-channel collaborative trigger counting function. The integrated controller supports cascading to expand more acquisition channels. High-precision counting and timing, the counting error is 1/1000, and the timing accuracy is 1 second. Through the “ferroelectric” storage of daily data, it can be stored for more than one month, and the historical data can be retransmitted after the meter reading channel is restored.
Intelligent power management
The system supports two 24V power inputs. One way is the main power source and the other way is the backup power source, realizing uninterrupted operation and energy-saving control.
Rich expansion interface
The integrated controller reserves multiple serial ports, network ports, etc., to support access to data from other dedicated instruments and equipment auxiliary systems.
Remote configuration
It supports remote parameter configuration of the integrated controller via wireless; the system is equipped with a dedicated PDA, which can be connected to and set up the integrated controller at a short distance.
Adapt to harsh working environment
The field communication products all support the working temperature of -25℃~70℃, which ensures the stability of equipment operation.
Applications:
This system has been successfully applied in many large domestic ports, and some of the application cases are as follows:
