Embodiment 1

[0032] like figure 1 As shown, the application provides a 3G module capable of monitoring the LED distribution system, which is used to monitor the host computer and network module of the LED distribution system.

[0033] like figure 2 As shown, the upper computer transmits data to the LED receiving card through Ethernet, and the LED receiving card transmits the data through the Ethernet chip RTL8212, and saves the data sent by the upper computer in the external memory of DDR2, and the saved video data After processing, the level conversion is performed by the 74HC245 chip and output to the LED display for display.

[0034] The 3G module of the monitorable LED release system specifically includes: a data transmission module for connecting with the host computer for communication; a control module connected with the data transmission interface for real-time monitoring of the host computer; a restart module connected with the control module, The restart module is connected wi...

Embodiment 2

[0046] On the basis of Embodiment 1, in order to prevent the single-chip microcomputer from breaking down, a reset module can also be set, and the reset module is connected with the control module to monitor the operation of the control module in real time. Perform a reset operation.

[0047] Specifically, the reset module is a watchdog circuit, such as Image 6 As shown, the watchdog circuit uses the combination of NC7S08 and AAT3526-3.08 chips. The IN1 signal of the NC7S08 circuit is the watchdog signal, which communicates with the IO port PC3 of the microcontroller. When the program runs away, the output of the NC7S08 chip is low power. Level, the output low level is input to the / MR signal of the AAT3526 chip, and the / RESET reset signal output of the AAT3526 chip is low level, which is sent to the / RESET reset IO port of the microcontroller to reset the microcontroller.

Embodiment 3

[0049]On the basis of Embodiments 1 and 2 or their combination, the power supply module is connected to the host computer, the host computer supplies power to the power supply module, and then the power supply module supplies power to other modules, and the power supply modules are respectively the data transmission module and the control module. The module and the restart module provide power.

[0050] Specifically in a specific embodiment, such as Figure 7 As shown, the power supply module is connected to the host computer through the PCI interface, and the power supply module takes 5V power from the hard disk interface IDE of the host computer, and obtains the required 3.3V power supply through LM1117-3.3 conversion.

Abstract

The invention relates to the technical field of real-time monitoring, in particular to the third generation telecommunication (3G) module capable of monitoring a light-emitting diode (LED) release system. The 3G module capable of monitoring the LED release system is used for monitoring an upper computer and a network module of the LED release system. The 3G module capable of monitoring the LED release system comprises a data transmission module, a control module, a restart module and a power supply module, wherein the data transmission module is connected with the upper computer and is used for carrying out communications, the control module is connected with a data transmission interface and is used for monitoring the upper computer, the restart module is connected with the control module, the upper computer and the network module, the power supply module is used for power supply for the data transmission module, the control module and the restart module, the data transmission module is in synchronous communication with the upper computer, receives real-time communication data and sends out into the control module, the control module is used for monitoring the communications with the upper computer according to preset judgment rules, if the communications between the upper computer and the control module is interrupted, a command will be sent out to the restart module, so that the upper computer and the network module can be restarted. Due to the fact that the running state of the upper computer can be monitored in real time, the problems that 3G network card is lost connection, the release system breaks down, and inconvenience is brought to a user are avoided.

Description

technical field [0001] The invention relates to the technical field of real-time monitoring, and more specifically relates to a 3G module capable of monitoring an LED distribution system. Background technique [0002] As a way of information dissemination, LED has been more and more widely used in all walks of life, and has been accepted by customers. Since LEDs are distributed in every corner of the earth, some are even placed in remote mountain villages and some unattended highways. It is very inconvenient to release and manage agents in the later stage, and the wiring method of wired network and the cost of optical fiber are difficult to be accepted by all customers. Therefore, how to effectively manage and maintain anytime and anywhere has become an urgent need for customers. [0003] The patent application with the authorized public number CN 202549253 U discloses a LED display control system, which discloses the following technical features. The system includes an MCU ...
