Embodiment 1

[0076] This embodiment is oriented to conventional applications and provides a mining security node for strong convective weather warning, such as Figure 4 shown. In the implementation, the PSoC chip selects the CY8C3866AXI-040 PSoC3 programmable system-on-chip chip produced by Cypress Company and packaged in TQFP-100. It integrates an 8051 solid core with a working speed of up to 67MHz, and has 24 universal digital blocks (UDB). Using the above resources, the calculation and storage operations required by the strong convective weather warning algorithm can be effectively performed. In implementation, its operating frequency reference frequency is an external active clock crystal oscillator of 24MHz. The variety of digital interfaces it supports also facilitates the connection of digital sensors and communication modules. In addition, it uses its internal operational amplifier module to build an input follower to monitor the resistance divider value of the supply voltage i...

Embodiment 2

[0085] This embodiment is aimed at application occasions of miniaturization and low cost. In the design, PSoC chooses the CY8C4248LQI-BL583 PSoC4 chip produced by Cypress Company and QFN package. CY8C4248LQI-BL583 integrates an MCU based on the ARMCortex-M0 structure, and supports Bluetooth BLE 4.2 communication modules, operational amplifiers, digital communication protocols (I2C, UART, SPI), general digital modules and other functions required for node design. The working clock in the implementation adopts 24MHz passive surface mount crystal oscillator. The way of constructing the follower for monitoring the supply voltage by the operational amplifier is the same as the previous embodiment.

[0086] PSoC4 in the node uses UART interface to connect MAX3232 to build two RS232 serial data channels for connecting external near-end devices.

[0087] The node wireless communication uses the AS62-T30 LoRa low-power wide area network communication module produced by Chengdu Zeyao....

Abstract

The invention provides a mining security and protection node for strong convective weather warning. The mining security and protection node for strong convective weather warning comprises an air pressure sensor, a thunder and lightning sensor and a PSoC module; the air pressure sensor is used for monitoring air pressure data at the node; the thunder and lightning sensor is used for monitoring thenumber of thunder and lightning and monitoring thunder and lightning storm front distance data; and the PSoC module is used for obtaining the data of the air pressure sensor and the thunder and lightning sensor according to a preset monitoring period, processing and analyzing the data to determine whether a strong convective weather is coming, and issuing a warning message when a strong convectiveweather is coming. Both the air pressure sensor and the thunder and lightning sensor are connected to PSoC module; an upper computer is connected to the PSoC module through a LoRa wireless communication module; a mobile intelligent device is connected to the PSoC module through a Bluetooth communication module; and a mining device is connected to the PSoC module through a fiber optic communication module. The mining security and protection node for strong convective weather warning has high integration degree, small boundary dimension, low cost and reliable performance, and provides effectivesupport for constructing a strong convective weather warning system in the mining field.

Description

technical field [0001] The invention relates to a mining security node, in particular to a mining security node capable of monitoring and warning strong convective weather. Background technique [0002] Severe convective weather refers to short-term heavy precipitation and convective strong winds that occur within the range of small and medium-scale weather systems and are accompanied by thunderstorms. Its duration is short but sudden, and it is a very destructive meteorological disaster. Meteorological disasters such as heavy rainfall, thunder and lightning, and strong winds in strong convective weather will have a relatively large adverse impact on mining operations. Surface runoff and infiltration caused by strong convective weather may lead to landslides, water seepage and flooding accidents, resulting in significant loss of personnel and property. The safety supervision departments of many provinces and cities in our country have successively requested to implement th...
