The second data communication terminal (232-RX, 232-TX) of telemetry terminal 1 is connected to the data communication terminal of data receiving service terminal 7 (located in the monitoring center). The mains power failure monitoring terminal of telemetry terminal 1 is electrically connected to the power output terminal of switching power supply module 5.

[0029] Preferably, the present invention provides an intelligent backup power system for a communication terminal, which further includes a boost regulator module 3. The enable control terminal (boost regulator control IO) of the boost regulator module 3 is communicatively connected to the enable control output terminal (boost regulator control IO) of the telemetry terminal 1. The power input terminal of the boost regulator module 3 is electrically connected to the power output terminal of the battery pack 6. The power output terminal of the boost regulator module 3 is electrically connected to the power input terminal of the sensing device 4.

This utility model does not impose any restrictions here.

[0031] like Figure 2As shown, the telemetry terminal 1 includes a power switching module 11, a control module 12, and a wireless communication module 13. The power switching module 11 is electrically connected to the power output terminal of the switching power supply module 5 and the power output terminal of the battery pack 6, respectively.

The data communication terminal of the wireless communication module 13 is communicatively connected to the data communication terminal of the data receiving service terminal 7 through an antenna.

[0032] Preferably, the telemetry terminal 1 further includes an LDO module 14, the power input terminal of the LDO module 14 being electrically connected to the power output terminal of the power switching module 11, and the power output terminal of the LDO module 14 being electrically connected to the power input terminal of the control module 12.

[0033] Specifically, the power switching module 11 includes a first diode D1 and a second diode D2. The anode of the first diode D1 is electrically connected to the power output terminal of the switching power supply module 5, and the cathode of the first diode D1 is electrically connected to the power output terminal of the control module 12. The anode of the second diode D2 is electrically connected to the power output terminal of the battery pack 6, and the cathode of the second diode D2 is electrically connected to the power output terminal of the control module 12.

[0034] When the 220V AC mains power supply stops, the switching power supply module 5 stops outputting. According to the principle of priority conduction of diodes, after the first diode D1 stops outputting, the second diode D2 will immediately enter the power supply mode. The LDO module 14 is unaffected and continues to supply power.

[0035] The control module 12 can be an APM32F407VGT6, the wireless communication module can be an EC20, or other modules or chips. This utility model does not impose any restrictions on these.

[0036] Furthermore, the telemetry terminal 1 also includes a power consumption adjustment control module 15. The power input terminal of the power consumption adjustment control module 15 is electrically connected to the power output terminal of the switching power supply module 5, and the power output terminal of the power consumption adjustment control module 15 is electrically connected to the mains power failure monitoring terminal of the telemetry terminal 1.

[0037] Preferably, the telemetry terminal 1 further includes a display module 16 (liquid crystal display module), the power output terminal of the power consumption adjustment control module 15 is electrically connected to the power consumption adjustment control terminal of the display module 16, and the data communication terminal of the display module 16 is connected to the third data communication terminal (serial communication) of the telemetry terminal 1.

[0038] Specifically, the power consumption adjustment control module 15 includes a relay and a VCC power supply. One end of the relay coil (relay pin 4) is electrically connected to the power output terminal of the switching power supply module 5, and the other end of the relay coil (relay pin 1) is grounded. The normally closed contact of the relay (relay pin 2) is electrically connected to the power output terminal of the VCC power supply, the normally open contact of the relay (relay pin 3) is grounded, and the common terminal (common contact) of the relay is electrically connected to the mains power failure monitoring terminal of the telemetry terminal 1 (i.e., control module 12).

[0039] Furthermore, the common terminal (common contact) of the relay is also electrically connected to the power consumption adjustment control terminal of the display module 16.

[0040] Preferably, the intelligent backup power system for a communication terminal in this embodiment further includes an SMS receiving terminal 8, which is communicatively connected to a data receiving service terminal 7 or a telemetry terminal 1. The data receiving service terminal 7 or the telemetry terminal 1 is equipped with a GSM SMS module, enabling SMS sending functionality.

[0041] Working Principle: After the mains power supply fails, the telemetry terminal 1 automatically and intelligently switches to backup power supply mode, powered by battery pack 6. When the 220V mains power supply fails, the switching power supply module 5 stops outputting. According to the diode priority conduction principle, after the first diode D1 stops outputting, the second diode D2 will immediately enter the power supply mode. The LDO module (which can be a TP6841S6) is unaffected and continues to supply power. After the 220V mains power supply fails, the relay (which can be a SRD-12VDC-SL-C) of the power consumption adjustment control module 15 switches its contact state when it detects no power (i.e., mains power failure). The relay port (pin) 5 switches from VCC to GND. Through the power consumption control terminal, the power supply of the LCD display module is turned off, reducing the LCD power consumption. At the same time, the power failure monitoring IO notifies the control module 12 of the mains power failure (from high level to low level). During periods of continuous mains power, sensor 4 is powered by the 12V output from the switching power supply module 5. After a power outage, the boost regulator module 3 can power sensor 4 to acquire the latest data. After acquiring the data, the power is cut off, and alarm information is reported to the data receiving service terminal 7 via the network communication module 13 for alarm notification. An alert SMS is automatically sent to a pre-set mobile phone number to the SMS receiving terminal 8. After the operation is complete, the device enters low-power mode, waiting for 220V to be restored. If necessary, it will wake up again to report the current device status.

[0042] The control module 12 in the telemetry terminal 1 will proactively adjust the communication frequency of the communication equipment to normal after the mains power is restored. The data receiving service terminal 7 will update its alarm status after the mains power is restored. After the mains power is restored, the battery pack 6 will be charged through the battery charging module 2.

[0043] In one implementation, after a 220V mains power outage, the switching power supply module 5 stops outputting. The control module 12 in the telemetry terminal 1 detects the mains power outage and automatically switches to the battery pack 6 power supply mode via the second diode D2 in the power switching module 11. The battery pack 6 changes from charging to output mode. The relay in the power consumption adjustment control module 15 switches state and turns off the power of the LCD module 16 through the power consumption control terminal to reduce power consumption. The power outage monitoring IO changes from high level to low level. After the control module 12 in the telemetry terminal 1 detects the level change, it uploads the information to the data receiving service terminal 7 via the wireless communication module 13. The data receiving service terminal 7 provides a warning message. The telemetry terminal 1 data receiving service terminal 7 or the data receiving service terminal 7 automatically sends a warning SMS to the preset mobile phone number to the SMS receiving terminal 7, prompting a power outage warning. During mains power operation, the switching power supply module 5 supplies power to the sensing device 4. During 220V mains power outages, the telemetry terminal 1 controls the boost and voltage regulation module 3 to supply power to the sensing device 4, acquire the latest data, and report it to the monitoring center, enabling the center to be aware of the latest status. After mains power is restored, the system automatically switches to mains power supply mode and charges the battery pack 6 via the battery charging module 2.

[0044] This invention employs a method of automatic power outage detection, automatic backup power switching, and wireless network notification via telemetry terminals to manage real-time monitoring of on-site mains power and automatic power switching measures. It provides ample raw information for the monitoring center's management work, reducing inaccurate data collection, unstable data transmission, and transmission failures caused by mains power environment factors, thus greatly improving the overall stability of communication equipment.

[0045] To address the problems existing in the prior art, this utility model innovatively proposes an intelligent backup power supply system for communication terminals. It adopts a method of automatic power failure detection, switching to backup power supply, and wireless network notification from telemetry terminals to monitor and manage the mains power in real time. This provides sufficient raw information for the management work of the monitoring center, improves the reliability of the power supply system for communication terminals, and also improves the timeliness of obtaining power supply information and sensor equipment information.

[0046] The present invention also includes a boost voltage regulator module. The enable control terminal of the boost voltage regulator module is communicatively connected to the enable control output terminal of the telemetry terminal. Under the control of the telemetry terminal, it can provide effective and stable power supply to the sensing device in the event of a mains power outage.

[0047] The telemetry terminal in this utility model includes a power switching module, a control module, and a wireless communication module. The power switching module is electrically connected to the power output terminal of the switching power supply and the power output terminal of the battery pack, respectively. The power output terminal of the power switching module is electrically connected to the power input terminal of the control module. This not only enables automatic detection of power outages on site, but also enables timely automatic switching of backup power.

[0048] The telemetry terminal in this utility model also includes a power consumption adjustment and control module and a display module. It can not only realize the automatic detection of power failure on site, but also adjust the power consumption of the backup power system in time when the mains power fails, so that the battery pack can run for a long time in a low power consumption state, achieving the purpose of effective monitoring.

[0050] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
