Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to enforcement In example or description of the prior art, the required accompanying drawing used is briefly described, it should be apparent that, describe below In accompanying drawing be only some embodiments of the present invention, for those of ordinary skill in the art, do not paying On the premise of going out creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the principle schematic of the present invention.
Detailed description of the invention
Describe the present invention below in conjunction with specific embodiment.
As it is shown in figure 1, a kind of new type auto gasifying device, use including protection CPU 1, described protection CPU 1 To complete the defencive function of automation equipment, and control CPU 2, described control CPU 2 in order to complete certainly The control function of dynamic gasifying device, described protection CPU 1 uses 32 Floating-point DSP of TI company TMS320C32 chip, described control CPU 2 uses 32 Samsung based on ARM kernel S3C44B0X processor, between described protection CPU 1 and described control CPU 2 by dual port RAM 3, CPLD single-chip microcomputer 4 is set up and is in communication with each other connection.That dual port RAM is selected is IDT71342, and it is 4K The memorizer of × 8bit.Having the independent data of two sets and address interface, IDT71342 has internal arbitration knot Structure, can arbitrate accordingly the read-write requests from two interfaces, therefore need not human intervention.
Described protection CPU connects 16 road sampling holders 11, it is achieved 16 bit AD samples, described protection CPU is circumscribed with flash module 12, real-time clock 13 and watchdog module 14, and described protection CPU is external There are extendible DI plate 15 and extendible DO plate 16.
In the present invention, described control CPU 2 is circumscribed with touch screen liquid crystal display screen 21.Described control CPU is arranged There are CAN 22, RS485 COM1 23.CAN function is then realized by SJA1000 chip, CAN is the serial communication bus of a kind of multiple host pattern, and Basic Design code requirement has high bit rate, High electromagnetism interference, and it is capable of detecting when any mistake produced.Described control CPU is provided with ether Network interface, it is achieved with the connection of Ethernet.This device Ethernet interface is to be realized by a piece of RTL8019AS, It does not has particular/special requirement, highly versatile to flush bonding processor.Unlike conventional network card design thinking, In embedded systems, system simplify the most individual main principle.General RTL8019AS is as net Card, time need a piece of EEPROM as configuration memorizer, determine the port address of communication, interruptedly Location, the physical address of network interface card, mode of operation, the information such as manufacturer;And in embedded systems, permissible Use the default configuration of RTL8019AS and some pins as the initial method of network interface card.So can save Save configuration memorizer, reduce the volume of Embedded Hardware Platform.RTL8019AS supports plug and play pattern With Non-Plug and Play pattern.In embedded systems, the peripheral hardware of network interface card typically infrequently plugs, so, For simplifying of system, configuration RTL8019AS is Non-Plug and Play pattern.There is fixing interruption, have Fixing port address, these configurations can be multiple in system electrification by the external terminal of RTL8019AS Automatically configure the when of position.
In the present invention, the TMS320C32 chip that American TI Company produces is high performance CMOS 32 Floating-point signal processor, it has powerful Mathematical treatment function.TMS320C32 chip is used to go bail for Protect chip and mainly consider that harmonic wave contained by the analog quantity of traction substation is relatively big, need a large amount of to use digital filtering skill Art, operand is big, and general CPU is difficult to meet its requirement.But the control pin of TMS320C32 chip is very Few, it is difficult to meet the control aspect requirement of Integrated Automation System for Traction Substation, therefore control CPU and have selected one Block S3C44B0X processor is as control core, and both exchange data by dual port RAM.
Have on dsp board the TMS320C32 chip of a piece of TI company, 128K × 32bit RAM, 1M × 32bitFLASH, real-time clock and watchdog chip constitute the core of dsp board;And by two panels 16bit AD676 chip, 32 LF398 sampling holders and two panels 16 select the analog multichannel switch chip of 1 The A/D convertor circuit that ADG526 is constituted can provide up to 32 road 16bit analog acquisition functions. CPLD chip EPM7192S is responsible for all Digital Logic and controls and AD conversion control.Dsp board does not has Outside terminal, it is connected with other circuit boards by bus board, is only responsible for realizing AD sampling, real time data Process and defencive function.ARM plate then has abundant interface, it be mainly responsible for realizing network communication and Human-computer interface control, exchanges data by dual port RAM with DSP simultaneously.The core of ARM plate is a piece of Samsung S3C44B0X chip, is furnished with 2M × 16bit FLASH, 8M × 16bit SDRAM.Ether Net function is to be realized by a piece of RTL8019AS, and DI plate can realize 28 way switch amount inputs altogether, Additionally also has the pulse input of 6 tunnel independences.4 blocks of DO plates can provide No. 32 relay outputs.Inspection Drafting board is mainly used in laying electrical quantity sensor and signal condition effect.Power panel then provides electricity for all circuit boards Source.Bus board is the bridge connecting each circuit board, panel be then provided with liquid crystal display screen, touch screen, keyboard and The displays such as display lamp, input equipment, be used for realizing man machine interface.
The above is only the better embodiment of the present invention, therefore all according to described in present patent application scope The equivalence that structure, feature and principle are done changes or modifies, in the range of being all included in present patent application.
