Data collectorProduct Categories:
The data collector models are: N9-100DC and N9-101DC, of which N9-101DC has a loop control function, the picture is as follows:
The product contains the following software and hardware features:
Three. Software functions
In response to the state's call for energy conservation in large buildings of state agencies and public institutions, this system has the following software functions:
3.1 Real-time acquisition
SACYB-2020 / 2012 contains a maximum of 4 universal serial interfaces. The serial port is used to collect data from the instrument through RS485.
All serial interfaces are abstracted into device files through the Linux device driver. The application only needs to operate the corresponding device files to achieve the operation of the corresponding serial interface.
The serial interface device file is located in the Linux system directory: / dev, and the device files are: ttyS0 to ttyS4. The corresponding relationship with each actual serial interface is shown in Table 4-1.
Table 4-1: Correspondence between serial device files and serial interfaces
The data collector supports two data collection modes: data center command collection and active timing collection. The timing collection period can be flexibly configured from 10 minutes to 1 hour.
One data collector supports data collection for no less than 32 metering devices.
A data collector should support data collection for different types of energy measurement devices, including energy meters (including single-phase energy meters, three-phase energy meters, multi-function energy meters), water meters, gas meters, and hot (cold) Scales, etc.
3.2 Data storage
This system uses SQLLITE database, which can store historical data for 7-10 days. The data collector is configured with a dedicated storage space of not less than 16MB
3.3 Data transmission
The data collector will remotely transmit the collected energy consumption data regularly. Generally, it is required that the energy consumption data of each item is uploaded once every 15 minutes, and the energy consumption data of no item is uploaded every 1 hour.
Before the remote transmission, the data collector encrypts the data packet.
If the data cannot be transmitted remotely at regular intervals due to a failure of the transmission network, etc., the data collector should use the stored data to resume the transmission after the transmission network returns to normal.
The data collector supports sending data to multiple data centers (servers) concurrently.
3.4 Loop control (N9-101DC only)
This system has a control function, and users can perform control configuration on the configuration tool according to their needs. The configuration software sends the configuration file to the collector,
The collector searches according to the number, which loop controller needs to be controlled. The customer can choose the manual control function, operate according to the actual situation, and control the air conditioner, socket, and lighting switch.
3.5 Local configuration and management
The data collector supports receiving commands such as query and time calibration from the data center. It also supports the location and diagnosis of faults in the data collection subsystem, and it reports fault information to the data center. The data collector should be equipped with an automatic recovery function, which can recover normal working conditions from failures when unattended.
