c, login management platform, you can remotely program, send, add, delete and other management.
d, remote time switch machine, remote insertion, remote monitoring screen play task.
3, the display can be divided into different groups or different customers, the content can be updated separately, can also be grouped, can play the same content, can also be different content.
4, through the timing and calibration, can achieve synchronous playback of the display content.
5 The best control scheme for outdoor LED display, no wiring, unlimited distance and fast transmission speed.
6, integrated design, low cost, simple operation.
7. The data center was established by Shenzhen Unisex, eliminating the need for customers to build and maintain servers.
8, easy maintenance and technical support to minimize system complexity.
9, for high-volume application customers, you can build your own server.
10, to solve the problem of communication restrictions between different operators, to achieve wireless connectivity.
11, rich information display: each information can be customized to its display mode and dwell time, can be arranged in any way, very flexible.
12, multiple language choices: such as numbers, letters, Chinese, English and so on.
13, a variety of information encryption methods: If you can set the information according to user needs to send information to add the identification code and check code, or only receive a dedicated number. Keep information safe.
14, easy to install and maintain: because there is no need to lay fiber optic cable or communication cable, the installation position of the wireless LED display is easy to choose. Modular design, easy to maintain and overhaul, and automatically save all information automatically dial-up Internet access, automatic redialing of dropped calls, ensuring reliable connection, wireless LED display automatically plays original information when power is turned off again after power off, anti-interference design, suitable for electromagnetic Harsh environment application, high and low temperature design, suitable for low temperature and high temperature working environment.
The advantage of the company's products and other companies is that we are WEB webpage management, do not need to download software, so it is more convenient for foreign trade customers.

Sixth, the system works:
1, Â Â Â Â Â Â Â Â Â After the control card, LED display, etc. are connected, it automatically connects to the 3G network data center and reports the serial number and affiliated users.
2, Â Â Â Â Â Â Â Â Â The data center manages all access control cards according to the user name; and monitors the online and offline status of the control card in real time.
3, Â Â Â Â Â Â Â Â Â After the user connects to the 3G network data center and logs in with his or her own username, the 3G network data center will naturally establish a mapping relationship with all the control cards of the user and control the user.
Six, the main product parameters:
1 control card parameters
3G one card (just one card, no need to receive cards, etc.)
3G cascade control card
receive card
MPPT Solar Controller
The main function of the MPPT Solar Controller is to realize maximum power point tracking (MPPT) in the solar power generation system to improve the energy utilization efficiency of solar panels. It is an advanced charge controller that can adjust the output voltage and current of the Solar Panel in real-time to keep the solar panel operating at the maximum power output point.
Main effect:
Maximum power point tracking: MPPT Solar Controller can accurately calculate the maximum power output point of the solar panel by monitoring the voltage and current of the solar panel in real-time and according to the characteristics of the solar panel. It then adjusts the panel's output voltage and current to keep it operating at its maximum power output point, maximizing the solar panel's energy conversion efficiency.
High energy utilization rate: MPPT Solar Controller's maximum power point tracking function can ensure that the solar panel is always operating in the best working condition, making full use of solar energy, thereby improving the energy utilization rate of the photovoltaic power generation system.
Charge control: In addition to achieving maximum power point tracking, MPPT Solar Controller also has a charge control function to protect the battery from overcharge and over-discharge damage.
Differences from other charge controllers:
Maximum power point tracking function: MPPT Solar Controller is a charge controller specially used in solar power generation systems. The biggest difference is that it has a maximum power point tracking function, which is used to improve the energy conversion efficiency of solar panels. Other charge controllers may not have this unique feature.
Energy efficiency: MPPT Solar Controller can improve the energy efficiency of solar panels through maximum power point tracking technology. Other charge controllers may only be able to charge in a fixed manner and cannot achieve maximum power point tracking.
Application scenarios: MPPT Solar Controller is mainly used in solar power generation systems, while other charge controllers may be suitable for different types of energy generation systems, such as wind power, hydropower, etc.
Overall, the main role of the MPPT Solar Controller is to achieve maximum power point tracking, improve the energy conversion efficiency of the solar panel, and protect the battery from overcharge and over-discharge damage. Compared with other charge controllers, it has unique advantages in energy utilization efficiency and maximum power point tracking and is suitable for applications in solar power generation systems.
