Embodiment 1

[0037] Such as Figure 1-Figure 3 As shown, this embodiment provides a substation voiceprint detection and recognition device based on the Internet of Things, including a central processing unit 1, a memory 2, a MEMS microphone 3, an ADC module 4, an FPGA module 5, and a communication module 6, the MEMS microphone 3, and the ADC Module 4, FPGA module, central processing unit 1 and memory 2 are connected sequentially, communication module 6 is connected to central processing unit 1, communication module 6 includes Ethernet 9 and NB-IoT wireless module 10, supports IoT data transmission, and is convenient for testing Data upload and data intelligent management, and realize multi-site voiceprint monitoring. NB-IoT has the advantages of wide coverage, multiple connections, fast speed, and low power consumption. Its characteristics are highly compatible with the ubiquitous power Internet of Things.

[0038] In this embodiment, the central processing unit 1 is an ARM9 S3C2410A proc...

Embodiment 2

[0049] In this embodiment, a substation voiceprint detection and recognition system based on the Internet of Things includes a plurality of substation voiceprint detection and recognition devices as in Embodiment 1 and an Internet of Things monitoring platform. The main function of the Internet of Things monitoring platform is to perform remote device management and upload data. management and data display. The Internet of Things monitoring platform remotely sends voiceprint signal collection instructions to the voiceprint detection and recognition devices of each substation, and processes the feedback voiceprint features, and generates and displays a trend chart of voiceprint feature changes in substations. In this embodiment, a data report with a cycle of days, months, and years displays the change trend chart of the voiceprint features.

[0050] The substation voiceprint detection and recognition device collects the original sound pressure signal, and the calculated A-weigh...

Description

technical field [0001] The invention relates to a substation characteristic detection device, in particular to a substation voiceprint detection and recognition device, method and system based on the Internet of Things. Background technique [0002] Voiceprint detection technology has been proved in UHV, power distribution and other fields that its characteristic quantity has obvious detection value for early warning of faults. The voiceprint comes from the response of the mechanical state of the structure, such as abnormal noise of high-resistance equipment, loose structure, friction, etc. Early failures have a higher sensitivity. [0003] As the terminal information collector of the ubiquitous power Internet of Things, the voiceprint monitoring unit is the most direct system unit to complete the data collection of the ubiquitous power Internet of Things system. The data collected and processed by the voiceprint monitoring unit is transmitted to the cloud by the wireless co...
