Dual card cellular router is usually used for projects with high speed requirements. If card 1 has a weak signal or runs out of traffic, it can automatically start card 2. Dual card cellular router is not suitable for projects that require low cost for power consumption and traffic.
The main feature of Dual card cellular router is Dual card dual mode, which enables different operators to be online at the same time, and can switch between wired and wireless at any time. Only by intelligent switching of multi-network mode and ensuring the backup of communication link switching, can we prevent disconnection and ensure that the whole project is not interrupted.
Environmental monitoring is usually in the outdoor environment, and it is suitable to complete the monitoring purpose by wireless means. It can form an environmental protection detection system on the detection platform by transmitting the status data of each emission pollution source. The environmental protection detection system can automatically sample pollution sources, online pollution factor monitoring and other data, so as to control the total amount of urban pollution emissions.
Dual card cellular router realizes outdoor networking in this environmental protection detection system, transmits pollution source data at the emission point through WIFI wireless mode, and uses VPN/VPDN virtual private network for security protection in transmission. If the signal of one of the 4G cards is too weak or no signal in a wide distribution, large number, long distance or remote place, the card 2 can be automatically switched without data loss due to no signal.
It is easy to have more interference factors in power projects, and Dual card cellular router has the function of automatically switching the current strongest signal, which can avoid some transmission interruptions caused by objective interference factors. In order to understand and master the power situation in time, monitor the power grid information, avoid leakage, power failure or other abnormal information will be quickly transmitted to the monitoring platform. Dual card router comprehensively monitors the important account of data, and VPN private network channel ensures the security of data system.
Dual card cellular router provides services such as parking space inquiry, reservation, entry and exit information recording in the smart parking lot. When vehicles enter the parking lot, they enter the gate in the way of license plate or vehicle identification, and lock or guide the parking space through Dual card cellular router, so as to achieve the purpose of convenient, fast and safe access for parking users.
At the same time, the camera in the parking lot records the situation on the spot, and there may be a sudden situation at any second, while the Dual card cellular router automatically switches to the current strongest network without disconnection, and has watchdog protection to achieve 24-hour downtime. The information at all times will be backed up by the best link.
Dual card 4G industrial router can not only transmit in the above three application environments, but also realize project applications in smart agriculture, industrial control, financial industry, video surveillance, pumping station monitoring and other projects. It is mainly aimed at the application environment with high speed and continuous monitoring without disconnection.
