[0022] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0023] The embodiment of the present invention provides a safety detection device for power transmission line monitoring equipment, such as Figure 1 As shown, it includes a photovoltaic module 1, a first battery group 2, a first BUCK (step-down DC regulated power supply) circuit 3, a 4G (fourth generation mobile communication technology) module 4, an MCU (microcontroller unit) 5, a security module 6, a first MOS tube (MOSFET metal-oxide semiconductor field effect transistor) switch 7, a second MOS tube switch 8, a third MOS tube switch 9 and a SOC (system on chip, System on Chip) module 10, wherein:

[0024] The photovoltaic component 1 is connected to the power supply of the first battery group 2, the photovoltaic component 1 is connected to the power supply of the SOC module 10, the output end of the first battery group 2 is connected to the input end power supply of the first BUCK circuit 3, and the first MOS tube switch 7 is arranged between the output end of the first battery group 2 and the input end of the first BUCK circuit 3.

[0025] The output end of the first BUCK circuit 3 is respectively connected to the power supplies of the 4G module 4, the MCU 5 and the security module 6, the second MOS tube switch 8 is arranged between the output end of the first BUCK circuit 3 and the 4G module 4, and the third MOS tube switch 9 is arranged between the output end of the first BUCK circuit 3 and the security module 6.

[0026] The first MOS switch 7, the second MOS switch 8, and the third MOS switch 9 respectively control the power on and off of the first BUCK circuit 3, the 4G module 4, and the security module 6. The first BUCK circuit 3 uses the different levels of DC voltage of its input conversion layer to power the MCU5, the 4G module 4, and the security module 6.

[0027] The MCU 5 is signal-connected to the control ends of the second MOS tube switch 8 and the third MOS tube switch 9 respectively, the SOC module 10 is signal-connected to the control end of the first MOS tube switch 7, the MCU 5 is signal-connected to the SOC module 10, the 4G module 4 and the security module 6 respectively, the SOC module 10 is signal-connected to the 4G module 4, and the 4G module 4 is connected to the monitoring platform 11 through the network.

[0028] The aforementioned security module 6 may include a positioning module and / or an audio module. The positioning module is used for locating and tracing the device after it is forcibly dismantled. The audio module includes an audio codec and a speaker, which is used for issuing a sound alarm after the device is forcibly dismantled.

[0029] The photovoltaic assembly 1 includes a solar panel and a charger, and the photovoltaic assembly 1 is connected to the first battery group power supply 2 through a charging circuit 12. The first battery group power supply 2 is in a charging state, and the battery is always kept in a fully charged state.

[0030] The photovoltaic module 1 is also connected to the power supply of the second battery pack 13 (for example, a lithium iron phosphate battery pack), the second battery pack 13 is connected to the input power supply of the second BUCK circuit 14, and the output end of the second BUCK circuit 14 is connected to the power supply of the SOC module 10 to supply power to the SOC module 10.

[0031] Specifically, MCU 5 is connected to SOC module 10, 4G module 4 and positioning module through UART (Universal Asynchronous Receiver-Transmitter) interface, MCU 5 is connected to audio module through IIS interface (Integrated Interface of Sound), SOC module 10 is connected to 4G module 4 through USB (Universal Serial Bus) interface, and 4G module 4 is connected to monitoring platform 11 through 4G network.

[0032] The MCU exchanges data with the positioning module through the UART interface to obtain positioning data and time data. The MCU and the 4G module exchange AT commands through the UART interface to transmit positioning information and malicious removal mark information. The MCU and the SOC module exchange data through the UART interface to start the anti-theft system within a period of time (for example, within N days, which can be set) after the device is officially installed.

[0033] The safety detection method of the aforementioned power transmission line monitoring equipment safety detection device includes:

[0034] S1: Before the transmission line monitoring device is installed, the first MOS tube switch 7 is closed by default, and the second MOS tube switch 8 and the third MOS tube switch 9 are opened by default. At this time, the safety detection flag in the MCU 5 program is set to "0", and the safety detection is not performed by default, and the safety detection program does not run. In this way, only the MCU runs with extremely low static power consumption.

[0035] S2: After the power transmission line monitoring equipment is installed, the SOC module 10 is powered on and working normally. When the set safety detection startup time is reached (for example, the safety detection strategy can be manually set to start N days), the SOC module 10 interacts with the MCU 5 through the UART and sets the safety detection flag in the MCU 5 program to "1", which means that the next time the MCU 5 is turned on again, the anti-theft positioning program will be automatically run and the safety detection will be started; at the same time, the SOC module 10 disconnects the first MOS tube switch 7, and the anti-theft positioning system is completely powered off and enters a zero power consumption state.

[0036] S3: When the power transmission line monitoring device is maliciously dismantled, the power supply of the SOC module 10 is disconnected, causing the SOC module 10 to fail. The first MOS tube switch 7 is in a closed state by default. At this time, the first BUCK3 circuit supplies power to the MCU 5. Since the safety detection flag of the MCU 5 has been set to "1", the anti-theft positioning program is started. The MCU 5 controls the second MOS tube switch 8 and the third MOS tube switch 9 to be closed, and the 4G module 4 and the security module 6 are powered on and work.

[0037] The positioning module transmits the positioning information and time information to MCU 5, which processes it into AT command format and interacts with 4G module 4 through UART. Then 4G module 4 transmits the relevant information and positioning information of the device to the monitoring platform through the network connection with the monitoring platform. After receiving the information, the monitoring platform can determine that the device has been maliciously dismantled according to the agreed protocol of the data, and parse out the key information and location of the device for easy traceability.

[0038] At the same time, the audio codec and speaker start to work normally, continuously playing the pre-set alarm sound source to issue a warning.

[0039] The present invention adds an anti-disassembly alarm system to the original system of the power transmission line monitoring equipment for safety detection, realizes the anti-disassembly alarm and tracing of the equipment through the safety detection device in the form of a circuit, after the equipment is maliciously dismantled, the circuit of the safety detection will work immediately, once the circuit of the safety detection is powered on, the main control system will determine that the equipment is maliciously dismantled, and will obtain the location information in real time, and send the maliciously dismantled mark and location information to the platform end through the wireless network, and the dismantled equipment can be easily found through the location information, reducing economic losses. And the preset alarm audio is played to warn the malicious dismantling personnel. In addition, the present invention adopts a low-power processing strategy, which will not affect the standby time. When the equipment is in normal working state, the circuit of the safety detection does not work, and the power consumption is zero. Moreover, when the circuit of the safety detection is working normally, only the positioning information and the anti-theft mark information are uploaded, and the power consumption is very low. Without increasing the power consumption, low-cost anti-theft positioning, alarm and other functions are realized.

[0040] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
