Description
Product Overview Series
DAE-D series station monitoring terminal is a monitoring terminal product developed for the ring network cabinet and small switching station which are more and more widely used in urban power grid. It has the functions of AC sampling, DC telemetering, remote control, remote signaling, wave recording, clock synchronization, event sequence recording, multi serial communication, multiple communication protocols, distributed network communication, local or remote online loading or updating application software, setting parameters, remote diagnosis and maintenance, and can store large capacity data. It is a new generation of measurement and control terminal device.
The measurement and control terminal of DAE-D series station contains Ethernet interface, adopts standard TCP/IP protocol and 10/100M communication rate; The internal bus of the device adopts CAN field bus network to realize the communication between modules. It can cooperate with the distribution network automation master station and sub station system to realize the collection and control of electricity of multiple lines, detect faults, locate and isolate fault areas, and restore power supply in non fault areas, so as to improve the reliability of power supply. It is widely used for real-time data acquisition and monitoring of power network in power system substations at all levels, railway power and electrification systems and other industrial control fields.
Main technical parameters
1. The universal international standard structure with functional modules as the unit is adopted, which effectively improves the insulation performance and anti-interference ability of the device. It can be installed in a decentralized manner or in a centralized way, so that it can be flexibly used in various occasions.
2. Modern digital electronic technologies such as network communication technology and high-performance single-chip microcomputer are adopted to achieve reliable performance and flexible and convenient use of the device.
3. Powerful network communication function. The device adopts standard TCP/IP protocol with 100M communication rate. It contains two Ethernet network chips with high communication speed and universal interfaces, which are used to form an internal communication network for mutual backup.
4. Redundant communication interface. The device contains up to four serial ports (RS485 or RS232 optional) to meet the communication requirements of different occasions.
5. The double CAN-BUS network without damaging priority arbitration is used as the communication network between modules. The CAN-BUS network works in a multi master mode, and any sub module can actively initiate information transmission to ensure the real-time and reliability of important event information transmission.
6. The software design adopts the open real-time multitask operating system Linux RTOS, which is used to realize the scheduling and management of various acquisition and control tasks. It not only improves the running reliability of the software, but also has better scalability. Software is standardized and reusable.
7. Strict anti-interference design and exquisite manufacturing technology improve the reliability. International standard industrial brand components are adopted, and the chip is packaged by SO to ensure the reliability of the device.
8. Maintainability and expandability design. In the dispatching center, through the telecontrol channel, the software of the main control device and each measurement and control device can be directly upgraded and modified online in the dispatching center. CAN-BUS bus communication is adopted between modules, and the hardware can be configured with different number and types of sub modules according to the project needs.
