SHDA-2116 distribution network automatic feederterminal takes high-performance 32 bit microprocessor as the hardware development platform and efficient embedded real-time operation as the softwaredevelopment platform, which has the following distinctive technicalcharacteristics：
1、Unified core public platform
based on a 32-bit microprocessor withCortex™-M4 core (with floating point unit) with a main frequency up to 180MHz,and has 16-bit synchronous sampling ADC chip, dual Ethernet, real-time clock,encryption chip, ferroelectric memory, FLASH and serial port and otherperipherals. At the same time, the multi-task real-time operating system is theembedded software platform. It has high performance information processingcapacity, supports Ethernet, wireless communication and serial communication,and has large interface capacity.
2、Large storage space
With a large capacity FLASH, you can store avariety of historical data, including event sequence records, fixed pointrecords, extreme value records, remote operation records, fault recording filesand line loss measurement files, and support historical data upload.
3、Diversified communication and upgrading methods
It has one maintenance port, two RS232/RS485serial ports and two Ethernet interfaces.
Serial interface: communication baud rateadjustable, can be connected to external line loss module and wireless moduleand other peripherals.
Ethernet interface: 10M/100M adaptive.
Communication protocol: Support the latest 101,104 protocols, and the main station can be wireless or fiber optic interaction.
Remote upgrade: The device can be upgradedthrough the maintenance port, serial port, and Ethernet communication port.
4、Intelligent power management
Real-time monitoring of backup power supply,including battery operating status, AC power supply status, battery activationcontrol, etc. After AC power loss, the backup battery can be seamlesslyinvested to ensure the normal operation of the termina.
Status monitoring: battery voltage, AC powerloss alarm, battery undervoltage alarm, and battery activation status.
Charge and discharge protection: preventovercharge, and automatically cut off the battery power supply when the batteryvoltage is lower than a certain value to prevent the battery from over discharge.
Activation control: manual activation, remotecontrol activation, timed automatic activation, etc., improve battery life.
Supports a variety of backup power supplies,such as lead-acid batteries, lithium batteries, and supercapacitors. Thespecific configuration depends on the supply requirements.
5、Strong maintainability
With local setting dip switches, it is easy toset the set value and delay when the device is not started or when the deviceis started.
With a variety of indicators, used to indicatethe various operating states of the equipment.
With a maintenance interface, operation andmaintenance personnel can be maintained locally or in the main station andother distant places.
6、Environment
Adapt to harsh environment, working temperature -40℃ ~ +70℃, anti-magnetic, shock-proof, moisture-proof. Altitude: ≤4000 meters,maximum absolute humidity :35g/m3 Atmospheric pressure: 70 ~ 106kPa.
Electromagnetic compatibility can meet therequirements of level 4 and above, can adapt to strong electromagneticenvironment, and the protection level is not lower than the IP67 levelrequirements stipulated by GB/T4208.
