GNSS performance
1. Star frequency requirements
The receiver supports GPS L1/L2, BD B1/B2, and BEidou III;
2. Static accuracy
The static calculation accuracy of the receiver meets:
Plane accuracy: ±(2.5+ 1×10-6×D) mm, elevation accuracy: ±(5+1×10-6×D) mm
3. GNSS antenna
External measuring antenna.
4. Collection mode
The receiver has conventional static and fast static observation modes. In flood season and other emergencies, it can be switched to fast static mode to encrypt the monitoring frequency to meet the needs of high-frequency monitoring.
The system performance
1. System platform
Industrial intelligent platform is embedded in monitoring terminal.
2. Storage space
The built-in memory is standard 4GB, optional 16G and 32G. The built-in memory can store the original observation data for no less than 90 days and the sampling frequency is 10 seconds/time, with the function of automatically overwriting old files when space is insufficient.
3. Network communication
The receiver supports 4G full netcom and fully supports mobile/Unicom/Telecom 2/3/4G network, with better compatibility, stronger signal and more stable connection.
The receiver supports wired access mode such as RS485RS232 serial port.
4. Data recording
The receiver has the function of storing and sending original data, and supports off-line resending.
5. Data interface
With RS485 and RS232 data interfaces, you can set parameters of the host through serial port commands. External dip Angle, alarm and other sensors, to provide power supply and network support for external sensors.
6, power characteristics
Power consumption: the receiver should have low power consumption, the average power consumption of the whole machine is 2 W.
The power supply. Industrial grade terminal interface for power supply, through the special power supply data line connected to the receiver, to provide stable power supply for the receiver.
7, power from the start
The receiver shall be capable of energized self-starting.
features
1, automatic online
The receiver has the function of automatic connection to Qianxun cloud service after startup, and supports remote configuration.
2. Remote configuration
The receiver supports remote configuration and on-site power supply to greatly reduce the work intensity and ensure construction safety. If necessary, upload frequency, firmware upgrade, power supply status and terminal device status call test can be modified.
3. Periodic sleep
The receiver should have periodic sleep function; Shut down GNSS and communication during dormancy to save energy and prolong service life.
4. Status monitoring
The receiver should have the function of monitoring the operating state. The receiver can transmit its own operating state, network intensity, external power supply voltage, ambient temperature and humidity (external sensor is required), firmware version number and other operating state information to the background.
5. Power monitoring
The receiver should be able to monitor the remaining power information of the external battery (percentage or voltage value) and transmit the monitored power information to the background.
6. Multi-source data fusion
According to the monitoring site, it can support the access of sensors such as rainfall, crack, tilt and acceleration, and conduct intelligent analysis on the monitoring site through multi-source data.
Appearance of the structure
1. Integrated design
Monitoring station receiver should adopt integrated design, integrated satellite antenna, GNSS board, communication; High integration, easy to install and debug in the field, enhance the protection performance of the equipment.
2. Fixed design
Fixed plate design
3, size and quality requirements
The size of the machine is about 187*158*35mm, and the total amount of the machine is less than 1Kg.
