There are a large variety of led screens. In order to meet different assembly conditions in daily use, there are curtain screens and raster screens.
1, LED curtain screen and LED grating screen are mainly used for indoor and outdoor large-scale real-time display engineering, curtain screen is used for large-scale stage rental more;
2. In order to ensure that the pixels of outdoor practical projects are sufficiently bright, the front of the
Module is sealed with silicone potting. The color of the silicone can be designed according to the project requirements, and the color card is specially designed to make this perfectly coordinated with the color of the external wall of the building.
3, the module outlet for the high and low temperature will be excellent silicone wire, with professional waterproof joints, professional design carefully built fully sealed waterproof structure protection level up to 1P67 can adapt to indoor and outdoor temperature and humidity environment, the working environment can reach - 20 and +80 degrees Celsius, can rain work;
4, multiple modules can form a full-color display wall;
5. It can be used as a linear light source instead of a digital tube, and the connection point light source light effects are more different;
6, can be arbitrarily combined with a variety of shapes, easy installation, does not affect the appearance and structure of the original object;
7, LED curtain display and LED grating display can be used in outdoor and indoor, requiring transparency, display pixels from a larger distance, there is a certain decorative effect of the use of large screen display occasions, it is living in ordinary regular display An LED display application between lighting and lighting;
8, the display unit for the strip, can be assembled into the inner arc display surface shape, the outer arc display surface shape, the inner circle display surface shape, S display surface shape, spherical shape and other special-shaped screen, there is no ordinary conventional display screen The display effect achieved;
9. The LED curtain display and LED grating display have the advantages of light weight, good wind resistance, easy installation, good heat dissipation performance, convenient front and rear maintenance, good waterproof performance, good anti-seismic performance, low cost of the auxiliary installation frame, no fan noise, etc. ;
10. When LED curtain display screens and LED raster display screens are used outdoors, approvals can be scrapped with the government and approved in the form of building lighting, bypassing the barriers of commercial display approval.
Others Water Meter
Bottom layer communication: M-BUS/485 collector and measurement meter transmit data by M-BUS/485 line with 4 channels, and can connect the meter according to any topological structure. Build in backup battery, could works for 48 hours normally, and the data can be saved for 10 years if power is cut off.
Middle layer communication: Middle layer communication means the communication between the concentrator and collector. This communication is by wireless RF way, no need of communication line. The wireless communication distance between the concentrator and collector can be about 3km at wide open area.
Upper layer communication: Communication methods indicate below can be selected between concentrator and management center:
(a) GPRS Communication Mode
(b)Telephone Line Communication Mode
(c) RS232 Communication Mode
(d) Ethernet Communication Mode
