Abstract

A real-time Chinese-English translation method and device with the character-type English LCD features that on the basis of Chinese-English translation equipment consisting of CPU system, English LCD, Chinese LCD and translator, an "interceptor" is additionally used, which uses the read and write commands from CPU to LCD as its trigger signal to intercept the data and commands transmitted between CPU and LCD. The screened character is real-time translated from Chinese to English by said translator for LCD.

Description

Character mode lcd shows real-time blocking Chinese and English interpretation method and device

Technical field

The present invention relates to a kind of character mode lcd and show real-time blocking Chinese and English interpretation method and device.

Background technology

In the Hanzify that English is read in the device read and instrument and meter, present method is mainly to adopt software engineering, in source code, add some Chinese and English character string dictionaries, finish Chinese and English translation liquid crystal display (LCD) with the method for software programming.As shown in Figure 1, in original instrument, there is an English character to show liquid crystal, if this English liquid crystal display is changed into Chinese liquid crystal display or increases a Chinese character liquid crystal display on this basis, classic method is to adopt the software source code of revising in the cpu system, the instrument that this method must have software source code and revise source code, therefore, when original instrument does not have the source code of cpu system or passive code revision instrument, then can't carry out this real time translation work.

Summary of the invention

When the purpose of this invention is to provide a kind of original instrument and not having the source code of cpu system or passive code revision instrument, the character mode lcd that still can carry out real time translation work shows real-time blocking Chinese and English interpretation method and device.

Technical scheme of the present invention is achieved like this, it reads on the Chinese and English translating equipment basis of reading cpu system, English LCD, Chinese LCD and translater including English, a kind of " blocker " is set, " blocker " utilize cpu system to the order of LCD write and read as trigger pip, communication data and order between interception cpu system and the LCD, character with screening is sent to the translater that has dictionary simultaneously, finish the translation of Chinese and English, translater writes Chinese LCD with translated Chinese.Interpretation method and the translating equipment that designs thus, it comprises cpu system, English LCD, Chinese LCD and translater, be characterized in, be connected to one " blocker " in cpu system and English LCD transmission, " blocker " shows real-time blocking Chinese and English translating equipment by the character mode lcd that translater and Chinese LCD connect into the bilingual type.

When original instrument did not have the source code of cpu system or passive code revision instrument, this method and device can make the English LCD of character type, realized that fast the real-time contrast translation of Chinese and English shows the LCD displaying contents Hanzify that urgent need is wanted.

Embodiment

When original instrument does not have the source code of cpu system or passive code revision instrument, designed the modular circuit blocker of similar " wiretap " function, as shown in Figure 2, blocker mainly is responsible for character and the order that the interception cpu system sends to English LCD, character with screening is sent to translater simultaneously, finish Chinese and English translation, translater writes translated Chinese among the Chinese LCD, this is a bilingual type blocker, if English LCD is removed at needs, and only keep under the situation of a Chinese LCD, this method is just not competent, reason is because cpu system not only sends data to English LCD, and might be from English LCD reading of data.If cpu system is reading of data from English LCD correctly, it will enter in abnormal handling procedure, and just this cpu system is to insighted other function of English LCD.For this reason,, become complete Chinese ocra font ocr and show liquid crystal, one " camouflage device " need be set replace original English LCD as shown in Figure 3 if thoroughly remove English LCD.The embodiment of the invention is explained as follows in conjunction with the accompanying drawings: successfully an electronic total station of Japan has been carried out Chinesizing work with the inventive method.The Presentation Function module of this electronic total station as shown in Figure 4, the DCPU modular circuit transmits data or reading of data from LCD to two identical lcd drivers simultaneously, and our purpose is that two English LCD are replaced to two Chinese LCD, since the DCPU modular circuit will be from two English LCD reading of data, adopt above-described " blocker " and " camouflage device " for this reason, as shown in Figure 5, in Fig. 5, we replace original English LCD and driver thereof with the camouflage device, catch DCPU and all swap datas and the order of pretending device with blocker, filter out the English character string that DCPU will show with filtrator on original English LCD, be presented on two graphical dots formation LCD after utilizing translater that the English character string is translated into the Chinese character string.

The camouflage device adopts and consistent or compatible chip or the circuit of former English LCD driving circuit; Present embodiment selects for use a liquid crystal chip KS0069 with Korea S's production of NEC total powerstation lcd drive chip HD44780 compatibility to serve as the camouflage device.

The design of blocker mainly is that to utilize the CPLD technology among the ASIC be the complex programmable logic designing technique, this technology utilize DCPU to the order of LCD write and read as trigger pip, the data and the order of communication between interception DCPU and the LCD.Data after the interception are given translater by filtrator with the character of command word and demonstration, and will read the state of LCD and read in the display random access memory information filtering such as character to fall, as shown in Figure 6.

Blocker and filter set lump together, it comprises d type flip flop group, command library, order comparer, timing sequencer and first-in first-out buffer (FIFO), as shown in Figure 7: 10 of data, condition lines that LCD and CPU communicate by letter link to each other with ten pins of CPLD (CY37128P100-125AC), CPU to the line trigger signal of LCD write or read also therewith the pin line of CPLD connect.When CPU to LCD write or LCD when CPU writes, data bus D0-D7, status signal RW, RS latch after passing through the d type flip flop group, utilize the negative edge of E to allow timing sequencer to start working simultaneously, timing sequencer is exported the order in the command library singly, at first to distinguish operation be CPU writes or CPU reads to LCD to LCD according to the state of RW signal wire, if read, then stops timing sequencer work; If write, then at first distinguishing according to the RS signal wire is write order or write data, if write data, then D0-D7 and the RS signal line states with the d type flip flop group writes among the FIFO together; If write order, then with the command word of command library with latch after data compare; If relatively failure, then the Next Command word compares till command library has all been got in the command fetch storehouse.If command library has all been got still relatively failure, then abandon; If relatively success then writes the D0-D7 and the RS of d type flip flop group among the FIFO this moment together, stop the work of timing sequencer simultaneously.After interception, filtering, the content of giving translater from FIFO is all command words and the data that CPU writes to LCD.Like this, translater just can be translated according to the content among the FIFO.
