Dustproof router

Abstract

The invention provides a dustproof router, comprising a master control chip, a reset circuit, a JTAG circuit, a non-frequent access data memory, a frequent access data memory, an external interface circuit and a power supply circuit. The reset circuit is connected with a reset port of the master control chip. The master control chip is an ARM Cortex-m3 chip. The non-frequent access data memory is a FLASH chip with SPI interfaces. The frequent access data memory is a ferroelectric memory with the SPI interface. The ARM Cortex-m3 chip provides two SPI interfaces. One SPI interface is connected with the FLASH chip, and the other SPI interface is connected with the ferroelectric memory. The ferroelectric memory is electrically connected with a dedusting unit. A timing dedusting controller, a dust monitoring controller and a motor controller are arranged in the dedusting unit. Microprocessors and wireless signal transceiving devices are arranged in the timing dedusting controller, the dust monitoring controller and the motor controller.

Description

technical field [0001] The invention specifically relates to a dustproof router. Background technique [0002] The power line carrier communication uses the power line as the communication medium. The disadvantage of the existing power line carrier communication technology is that because many different types of electrical equipment are connected to the power grid, the power grid has attenuation, noise and interference to the carrier communication signal. The point-to-point communication distance of power line carrier communication is greatly limited. Therefore, the communication method of expanding carrier communication in the future is mainly to introduce the idea of ​​relay routing in power line communication. At present, domestic mainstream carrier manufacturers have proposed a variety of routes. Algorithms and modules, but most of them are placed together with the carrier chip, and only for a certain carrier chip, which has great limitations, and the existing routers do...

[0002] The power line carrier communication uses the power line as the communication medium. The disadvantage of the existing power line carrier communication technology is that because many different types of electrical equipment are connected to the power grid, the power grid has attenuation, noise and interference to the carrier communication signal. The point-to-point communication distance of power line carrier communication is greatly limited. Therefore, the communication method of expanding carrier communication in the future is mainly to introduce the idea of ​​relay routing in power line communication. At present, domestic mainstream carrier manufacturers have proposed a variety of routes. Algorithms and modules, but most of them are placed together with the carrier chip, and only for a certain carrier chip, which has great limitations, and the existing routers do not have dustproof function, so there is an urgent need for an anti-dust dust router to solve the above problems
