Embodiment
Please refer to Fig. 1, the embodiment one of the utility model handheld terminal comprises:
Controlled processing unit 110;
Present embodiment adopts the standard Linux operating system of open source code, based on this operating system, can adopt hardware driving development interface program to develop selectively and installing peripherals 200 corresponding equipment drivers, and the interface of peripherals correspondence is set in interface unit 130, to dispose peripherals 200 as required; And if need expand peripherals 200 in the later stage, only need program development of hardware driving development interface and installation newly added equipment corresponding equipment driver based on this operating system, the interface that also can increase the newly added equipment correspondence as needs in interface unit 130 can be realized.
As seen, the utility model can dispose peripherals as required, therefore applicable to multiple industry, also can expand peripherals as required to increase function in the later stage, adapts to the development of industry, has the advantage that life cycle is long, cost performance is high.
Please refer to Fig. 2, in embodiment more specifically, controlled processing unit 110 comprises central processing unit 111 and the Programmable Logic Controller 112 that is connected with central processing unit 111; Storage unit 120 comprises flash memory 121 and random access memory 122; Interface unit 130 comprises display interface 131, keyboard interface 132, printing interface 133, scan interface 134, power interface 135, wireless module interface 136 and IC-card interface 137; Each interface of interface unit 130 is connected with Programmable Logic Controller 112 with the central processing unit 111 of controlled processing unit 110 by signal wire 140.By each interface of interface unit 130, present embodiment can external corresponding peripheral device 200: display 201, keyboard 202, printer 203, scanner head 204, power supply adaptor 205, SIM card seat 206 and IC-card slot 207.
