Description

A kind of dust-proof router

Technical field

Present invention relates particularly to a kind of dust-proof router.

Background technology

Power line carrier communication is used as communication media, the deficiency of existing electric line carrier communication technology with electric lines of force Part is: owing on electrical network and connect a lot of different types of electrical equipment, electrical network exists decay, makes an uproar multicarrier communication signal Sound and interference so that the point-to-point communication distance of power line carrier communication has obtained the biggest restriction, therefore, following expansion carrier wave The method of communication of communication, mainly introduces the thought of transistroute, the carrier wave producer of current domestic main flow in power line communication It is proposed multiple routing algorithm and module, but a lot of major part is all to put together with carrier chip, and just for certain A kind of carrier chip, has significant limitation, and existing router does not have dust reduction capability, so being badly in need of a kind of dust-proof Router is to solve the problems referred to above.

Summary of the invention

Present invention aims to the deficiencies in the prior art, it is provided that a kind of dust-proof router, this dust-proof router can To solve the problems referred to above well.

For reaching above-mentioned requirements, the present invention adopts the technical scheme that: provide a kind of dust-proof router, this dust-proof router Including main control chip, reset circuit, jtag circuit, non-frequent access data storage, frequent access data storage, to external Mouth circuit and power circuit；Reset circuit connects the reseting port of main control chip, and jtag circuit connects the program of main control chip and surveys Examination port, non-frequent access data storage and frequent access data storage connect the corresponding serial peripheral of main control chip and connect Mouthful, power circuit provides working power for whole module；External interface circuit includes the first UART circuitry and the second UART circuitry, First UART circuitry connects PORT COM and the concentrator MCU of main control chip, and the second UART circuitry connects the communication of main control chip Port and carrier chip；Described main control chip uses ARM Cortex-m3 chip, and described non-frequent access data storage is band The FLASH chip of SPI interface, described frequent access data storage is the ferroelectric memory of band SPI interface, ARM Cortex- M3 chip provides two SPI interface, and one connects FLASH chip, and another connects ferroelectric memory；Above-mentioned ferroelectric memory and dedusting Unit electrically connects, and above-mentioned dust removing units is internally provided with timing dusting controller, dust monitor controller and electric machine controller, institute State and inside timing dusting controller, dust monitor controller and electric machine controller, be provided with microprocessor and wireless signal transmitting-receiving Device.

This dust-proof router has the advantage that as follows: and use contact pin and channel plate to be attached, and versatility is good, can be extensively Check meter for power line carrier, intelligent building, Smart Home, the field such as security protection.The descending energy of routing module that the present invention provides is held concurrently Hold multiple carrier chip, there is good versatility, and dust-proof function can be realized.
