Abstract

The utility model discloses a VPS (Virtual Private Server) all-in-one machine which comprises a mainboard, a display screen, a touch screen and a keyboard, wherein an analogue acquisition module and an ARM core plate are arranged on the mainboard; the analogue acquisition module is connected with the ARM core plate; the ARM core plate is connected with a frequency converter control module; the ARM core plate is also connected with a power source module on the mainboard; an interface which is connected with controlled equipment is also formed in the mainboard and is connected with the ARM core plate. After the technical scheme is adopted, the VPS all-in-one machine which is capable of efficiently and reliably improving efficiency is manufactured; the VPS all-in-one machine is light and convenient in size and simple in structure, program is burned for only one time, and compared with the traditional HMI (Human Machine Interface) upper computer communication mode and the traditional PLC (Programmable Logic Controller) lower computer communication mode, the VPS all-in-one machine is simpler and more reasonable; the antijamming capability is stronger than that of the traditional RS 485, a CPU (Central Processing Unit) directly manages input and output, no communication is needed, and no communication failure exists; the input/output speed is rapid and can reach 1MHz, and the VPS all-in-one machine is rapider than the traditional RS 485 communication mode.

Description

A kind of VPS all-in-one

Technical field

The utility model relates to VPS field, particularly a kind of VPS all-in-one.

Background technology

VPS technology refers to a server is divided into multiple virtual technology of specially enjoying server.Now general is technology as shown in Figure 1, and HMI1 connects PLC2, and the mode that PLC2 connects controlled device 3 is current generally popular industrial automation solution, most employing RS485 communication between HMI man-machine interface and PLC.HMI is man-machine interface, the general host computer that cries, PLC is the electronic installation of the digital operation operation of a kind of special application under industrial environment and design, the general slave computer that cries, in the more severe commercial Application of electromagnetic environment, there is anti-interference more weak shortcoming in the RS485 communication of upper and lower computer, main cause is that on-the-spot EMI causes RS485 to occur the raw data mistake of Frame, even if RS485 adopts the method for difference, also cannot well avoid the appearance of this type of situation.The disadvantage of upper and lower computer communication modes maximum is that host computer can not be in the real-time real-time status of knowing slave computer high speed signal of the very first time.In other words, even if slave computer has collected live signal, also need first live signal to be packaged into communication data frame, and then transfer data to host computer by RS485 according to setting baud rate.Like this, key signal can not pass in time host computer and show in real time and computing, has caused the delay of signal.

Utility model content

In order to address the above problem, the utility model provides a kind of VPS all-in-one of raising the efficiency that can high efficient and reliable.

A kind of VPS all-in-one in the utility model, comprise mainboard, display screen, touch-screen and keyboard, described mainboard is provided with analog acquisition module, ARM core board, described analog acquisition module is connected with ARM core board, described ARM core board is connected with frequency transformer control module, described ARM core board is also connected with the power module on mainboard, is also provided with the interface being connected with controlled device on described mainboard, and described interface is connected with ARM core board.

In such scheme, described mainboard is provided with multiple analog acquisition modules.

In such scheme, described analog acquisition module is connected by SCIS parallel bus with ARM core board.

In such scheme, described mainboard is provided with multiple interfaces.

Advantage of the present utility model and beneficial effect are: the utility model provides a kind of VPS all-in-one of raising the efficiency that can high efficient and reliable.Lightweight and portable in volume, simple in structure, and only need burning one secondary program, than traditional HMI host computer and PLC slave computer communication modes more easy rationally.Antijamming capability is more eager to excel in whatever one does than traditional RS485, and CPU directly manages input and output, need not communication, and can Communications failure.Input and output speed is fast, can reach 1MHZ, more a lot of soon than traditional RS485 communication modes.

Brief description of the drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the principle schematic of prior art;

Fig. 2 is principle schematic of the present utility model.

In figure: 1, HMI 2, PLC 3, controlled device 4, mainboard

5, display screen 6, touch-screen 7, keyboard 8, analog acquisition module

9, ARM core board 10, frequency transformer control module 11, power module 12, interface

Embodiment

Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.

As shown in Figure 2, the utility model is a kind of VPS all-in-one of raising the efficiency that can high efficient and reliable, comprise mainboard 4, display screen 5, touch-screen 6 and keyboard 7, mainboard 4 is provided with analog acquisition module 8, ARM core board 9, analog acquisition module 8 is connected with ARM core board 9, and ARM core board 9 is connected with frequency transformer control module 10, and ARM core board 9 is also connected with the power module 11 on mainboard 4, on mainboard 4, be also provided with the interface 12 being connected with controlled device 3, interface 12 is connected with ARM core board 9.Mainboard 4 is provided with multiple analog acquisition modules and interface.Wherein analog acquisition module 8 is connected by SCIS parallel bus with ARM core board 9.

VPS all-in-one is self-defined SCIS parallel bus, need not walk RS485 communication, CPU directly manages each input and output pin, the top speed that all input/output signals are worked simultaneously can reach 1MHZ, because VPS all-in-one is by Hardware I RQ interrupt mechanism, directly carries out the software filtering of input and output pin and management at a high speed, the lengthy and tedious processes such as task switching that need not be traditional, really can accomplish high efficient and reliable, and only need burning one secondary program, convenient and simple.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
