[0002] Today, terrestrial digital TV coverage systems are facing the technical requirements of achieving digitization and intelligence. Scientifically maintaining and managing equipment, effectively improving the broadcast quality and efficiency of terrestrial digital TV transmitters, and reducing the dependence of equipment on personnel are the current mainstream development trends.

[0003] Terrestrial digital television coverage monitoring systems are a crucial component of the digital television coverage network and a crucial guarantee for the safe broadcasting of terrestrial digital television. However, because transmitters are often located high on towers or mountains, the workload is intense for on-duty personnel. Long hours on duty can lead to complacency and negligence, and management is inconvenient. Furthermore, maintenance personnel struggle to quickly locate and troubleshoot faults, resulting in degraded transmitter quality. In particular, sudden power outages can lead to prolonged broadcast downtime if not promptly repaired. In particular, some signal-replacement transmitters operating in the field are often unmanned, making timely repair impossible in the event of a power outage or other emergency. The transmitters currently in use by local radio and television bureaus have simple network communication interfaces and protocols, and they encompass multiple brands, making retrofitting difficult and costly. Therefore, implementing network monitoring is virtually impossible under current conditions. Summary of the Invention

[0021] The present invention will be described in further detail below with reference to the accompanying drawings.

[0022] like Figure 1 As shown, the utility model includes a casing, a CPU mainboard module 1, a 4G transmission module 4, a power failure detection energy storage module 3, and a power supply module 2; the casing is a waterproof casing, and each module is located inside the waterproof casing and is connected by wires.

[0023] The 4G transmission module adopts a patch-type SIM card, which can ensure long-term stable contact operation.

[0024] The power supply module converts 220V into DC12V voltage, and connects the DC12V voltage to the power failure detection energy storage module through a wire. The output of the power failure detection energy storage module supplies power to the mainboard and the 4G transmission module respectively.

[0025] The CPU mainboard module is connected to the 4G transmission module via a wire, and exchanges data with the monitoring and management platform via 4G wireless mode according to relevant protocols to achieve remote monitoring and management, as well as parameter configuration modification.

[0026] When the device is operating normally, the power outage detection energy storage module uses the DC12V provided by the power module to power the CPU motherboard module and the 4G transmission module. The power outage detection energy storage module is equipped with a reset chip. When the system loses power and the supply voltage falls below the reset chip threshold, the reset signal output by the reset chip will jump. The power outage detection energy storage module transmits this signal to the CPU motherboard module for processing. The power outage detection energy storage module is also equipped with a large-capacity capacitor. During normal operation, the capacitor charges and stores energy. When the power is cut off, the large-capacity capacitor begins to discharge, ensuring that the device continues to operate for a period of time, allowing the device to promptly report the power outage alarm information and the transmitter parameters before the power outage to the monitoring and management platform via the 4G wireless network.

[0027] like Figure 2The monitoring terminal device shown includes an LED light 6, a debugging serial port 7, a USB interface 8, a network port 9, an antenna 10, and a power interface 11 for external display. The LED light 6 includes a power indicator light, a device operation status indicator light, and a 4G status indicator light. The several indicator lights are controlled by the power module, the CPU motherboard module and the 4G transmission module respectively. The LED light is clamped on the casing through a waterproof cap. The DB9 interface of the debugging serial port is fixed to the casing through a nut. RX, TX and GND are connected to the three-core serial port socket of the CPU motherboard module through a three-core wire. A waterproof cap is installed outdoors for protection. The USB interface is a reserved upgrade interface and is fixed to the casing with a waterproof interface knob. It is connected to the USB port of the CPU motherboard module through a USB cable. The network port is connected to the CPU motherboard module internally and to the transmitter externally. The network port can be used to collect parameter information of the transmitter and re-encapsulate the data. The antenna uses an integrated waterproof antenna, one end of which is fixed on the casing and the other end is connected to the antenna interface on the 4G module through a radio frequency cable. The power interface uses a waterproof aviation plug for an external 220 power supply. The 220V power enters the device and is connected to the power module and converted to DC12V for use by the device.

[0028] The monitoring terminal device provided in this embodiment connects to the transmitter locally via a network port and exchanges data with the monitoring and management platform via 4G wireless communication, enabling remote monitoring and management of the transmitter, as well as parameter configuration modification. It is also equipped with a power outage detection and energy storage module, which can detect power outages and ensure that the device continues to operate for a period of time, allowing the device to promptly report power outage alarm information and transmitter parameters before the power outage to the monitoring and management platform via the 4G wireless network.

[0029] The technical solution of the present invention can conveniently carry out networking monitoring and management of the existing transmitters in use without the need to modify the transmitters. At the same time, it has the functions of power failure detection and maintaining continuous operation for a period of time after power failure. The power failure alarm information and the transmitter parameters before the power failure can be reported in time, so that the fault can be eliminated in time and the long-term broadcast suspension accident can be avoided.
