Background technology
Present recording instrument without paper mainly is made up of mounting guide rail, 16 central processing units, LCD LCD, input end of analog signal rows.Thoroughly having substituted tradition has paper, China ink, pen and the mechanical transmission component thereof of paper registering instrument, and having overcome tradition has various faults such as paper registering instrument paperboard, card pen, broken string, has removed the scene from and has changed paper, change-fountain pen, changes line services in a large number such as China ink.But along with integrated circuit (IC) chip technology rapid development such as processor chips, storage core chip technologies, and the continuous improvement of display technology, the memory capacity and the processing speed of existing recording instrument without paper have not reached user's performance requirement.On the other hand, existing recording instrument without paper shows that in order to reach high resolving power its screen is often relative with volume very big, if use small size and the small screen to show, uses monochromatic screen or blue screen again, and interface display content dullness is not abundant.
The utility model content
Therefore, at the above-mentioned deficiency of prior art, the utility model proposes that a kind of storage space is bigger, processing speed is faster and the colored recording instrument without paper of volume miniaturization.
The technical solution of the utility model is:
Small sized colour recording instrument without paper of the present utility model, the electronic circuit that comprises crust of the device and be arranged in the shell is formed, described electronic circuit is specifically: the input/output port of CPU control module is connected in AD digital to analog converter unit and RS485/232 interface, the output port of CPU control module is connected in the alarm relay output unit, the output port of CPU control module is connected in the alarm relay output unit, the input port of CPU control module is connected in push-button unit, the data bus port of CPU control module is connected in the FLASH memory cell, TFT color LCD actuator unit and USB host device interface, the input end of described AD digital to analog converter is connected in the analog multichannel switch unit, and the output terminal of described TFT color LCD actuator unit is connected in the TFT color LCD.
Further, described CPU control module is an arm processor.
Further, described AD digital to analog converter unit is 24 AD digital to analog converters.
Further, described FLASH memory cell is the serial FLASH memory unit.
Further, described TFT color LCD actuator unit is the actuator unit that the CPLD chip constitutes.
Further, described TFT color LCD is 3.5 cun a TFT color LCD.
The utility model adopts as above technical scheme, has following useful technique effect:
(1) adopt 3.5 cun TFT color LCDs, have the advantage of wide visual angle, high brightness, high-contrast, its interface display is abundant in content, colour, and friendly interface, easy to operate.
(2) make the product miniaturization, power consumption reduces, and uses that to occupy the space little, uses to user installation and brings great convenience.
(3) aspect of performance is but identical with large-scale volume instrument, and certain aspect performance also improves a lot, and is faster as processing speed, memory headroom is bigger, and extendible capacity to 40 megabyte supports 32MB to carry out data storage to the USB flash disk of 8GB simultaneously, compatible strong, can compatible most on the market USB flash disk.
Description of drawings
Fig. 1 is a circuit block diagram of the present utility model.
Embodiment
Now with embodiment the utility model is further specified in conjunction with the accompanying drawings.
Consult shown in Figure 1, small sized colour recording instrument without paper of the present utility model, the electronic circuit that comprises crust of the device and be arranged in the shell is formed, described electronic circuit is specifically: the input/output port of CPU control module 1 is connected in AD digital to analog converter unit 2 and RS485/232 interface 6, the output port of CPU control module 1 is connected in alarm relay output unit 4, the input port of CPU control module 1 is connected in push-button unit 5, the data bus port of CPU control module 1 is connected in FLASH memory cell 7, TFT color LCD actuator unit 8 and USB host device interface 9, the input end of described AD digital to analog converter 2 is connected in analog multichannel switch unit 3, and the output terminal of described TFT color LCD actuator unit 8 is connected in TFT color LCD 10.
Preferably, described CPU control module 1 is an arm processor, being 32 ARM(CORTEX kernels that adopt STMicw Electronics (ST)) processor is as the CPU of this instrument, this CPU peripheral hardware is abundant, high integration, the use amount that this can reduce the CPU peripheral components effectively reduces the area of PCB greatly.Described AD digital to analog converter unit 2 is 24 AD digital to analog converters.Described FLASH memory cell 7 is serial FLASH memory unit, simultaneously can reduce to take the PCB space again for effectively prolonging storage time, we have adopted the high capacity serial FLASH memory, this device adopts the encapsulation of SOP-8 small size, instrument memory capacity can be accomplished the 40MB(40 megabyte), reach 30.3 days storage time (logging interval 1 second), 9102.2 my god (logging interval 5 minutes), further strengthen as logging interval, to increase writing time with the multiple of time, therefore this instrument has not only realized miniaturization, and is being greatly improved than similar large product aspect storage time.Described TFT color LCD actuator unit 8 is actuator units that the CPLD chip constitutes, this CPLD chip (programmable logic device (PLD) chip) is as hardware carrier, utilize VHDL language that the sequential of LCD is described, and the INTEL bus interface that realizes 8 is connected with CPU control module 1, so just can avoid third party's display driver plate of using volume bigger than normal, reduce requirement the PCB installing space.This just all has been integrated into the former function of two to three large circuit board realizations possibly on the littler relatively plate, thereby realizes showing miniaturization.Described TFT color LCD 10 is TFT color LCDs of 3.5 cun.
