The utility model has the benefits that due to high-speed synchronous data collecting, more signal channels and support to a PLC (Programmable Logic Controller) the system is configured very flexibly and meets the requirements of the majority of condition monitoring users. Compared with the system requiring the combination of a plurality of devices of different types, the modularized condition monitoring device based on the FPGA has obvious technical and economical advantages.
Description
Technical field
The utility model relates to a kind of state monitoring apparatus, especially relates to a kind of module state monitoring apparatus based on FPGA.
Background technology
Along with improving constantly of field programmable gate array FPGA capacity and density, the system that original discrete component is realized can realize the system integration at the jumbo FPGA of a slice, to reduce the cost of product, FPGA also has DSP and the incomparable advantage of microprocessor on speed and reliability.In electric system, in the hardware design of electronic installation, begun to adopt FPGA, and finished some the important work in the system, as data collection, data processing etc.
Common data acquisition implementation is to adopt microprocessor, realize acquisition controlling by software, the remarkable shortcoming of this way is: by programmable sampling and read translation data, can't give full play to the speed of hardware system, limited the raising of sampling rate, when the measured signal frequency is higher, can't realize high speed acquisition.More when the number of channels that needs synchronous acquisition, when simultaneously needing the slow variable signal again, traditional data acquisition modes more can't be competent at; At different users, the value volume and range of product of passage is respectively had difference, must the module device because the value volume and range of product of passage is changed, to specific user or the quantity that seems is not enough, or just redundant too many, thereby wasted resource.
Summary of the invention
At the deficiency that exists in the existing apparatus, but the technical problem to be solved in the present invention provides a kind of data acquisition and data transmission technology of many synchronous processing 84 road high-speed channel signals.But this invention improved data acquisition speed, increase processing signals passage quantity and realized uploading fast of image data in enormous quantities, simultaneously more flexible in the configuration of signalling channel kind and quantity, the feasible demand that just can satisfy different users with a kind of device.
The utility model adopts following technical scheme to realize the foregoing invention purpose:
Comprise mainframe box, expansion cabinet, man-machine interface that the CPU module is installed, it is characterized in that, also comprise in the mainframe box: the high speed mould is gone into module, key signal module, and wherein, CPU module, high speed mould are gone into module, the key signal module is connected by data bus.
The beneficial effect that the present invention has is:
Synchronous data collection at a high speed, more signalling channel and to the support of PLC, make system configuration very flexible, can satisfy most of status monitoring user's requests, the system that forms with many variety classes devices combinations of those needs compares has tangible technology and economic advantages.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Of the present utility modelly by special-purpose module of power supply module, CPU module, various function and module base plate is installed and is formed, mainly contain down several parts:
Mainframe box: the cabinet that the CPU module is installed.Base plate is installed is divided into two kinds of different types of 6 grooves and 10 grooves, therefore mainframe box can be selected any of above-mentioned installation base plate for use, the main function module that uses is " high speed analog signal collection module ", " key signal processing module " etc. on the mainframe box, and the also compatible MB60 of mainframe box is routine PLC module when being both.
Expansion cabinet: the cabinet (expansion cabinet and MB are that routine module is an existing P LC product, are not contents of the present invention, and the present invention has the ability to PLC product compatibility) that the CPU module is not installed.Equally also can select dissimilar installation base plates such as 6 grooves and 10 grooves for use.It is routine module that the expansion cabinet can only be used for expansion technique of PLC, can not expand the module that " high speed analog signal collection module ", " key signal processing module " etc. need high-speed data to handle.
Man-machine interface: comprise mouse, keyboard, display, be used for the terrain monitoring and device is configured operation.
Wherein expand cabinet installation base plate and only support the CAN network interface, mainframe box had both supported the CAN network interface also to support parallel data control bus interface, thereby can handle module with high-speed data apace and carry out exchanges data, and the expansion cabinet does not have this kind function.
Because this device CPU module has Ethernet interface, can be uploaded to host computer to image data in real time, and host computer also can be passing to the terrain state monitoring apparatus under the operational order, thereby the user can dispose man-machine interface selectively.
The CPU module mainly is made up of FPGA, its steering logic is partly born the management of signalling channel data acquisition and control, the RAM buffer is that two-port RAM is used for temporary image data, fix time and be used to provide Synchronous Sampling Pulse, spectrum analysis is finished by hard logic FFT module, the embedded PowerPC stone of FPGA is born the management and the control of total system, comprise data acquisition, data transmission of Ethernet, based on the graphical interfaces of MiniGUI, CAN exchanges data etc., can be provided with and modifier configuration parameter etc. by man-machine interface (VGA, mouse, keyboard).
The built-in Linux operating system exploitation is adopted in software development, realizes the support to MiniGUI, FLASH, I2C bus, CAN bus, Ethernet etc. on (SuSE) Linux OS.
The CPU module carries out exchanges data by data bus, I2C bus and CAN bus and other module in figure two, the CAN bus is used for compatible PLC product, data bus is used for going into module and key signal module exchange Monitoring Data with the high speed mould, the I2C bus is used for these two modules are configured, the realization state lights a lamp, open into, leave and functions such as self check.
The high speed mould is gone into module and is used to handle various sensor output signals, as low-frequency shock transducer signal, current vortex sensor signal, pressure pulsation sensor signal etc., but the high speed mould is gone into the signal that module sends the sensor here and is nursed one's health and be converted into the AD process range, after the AD conversion, image data is submitted to the CPU module by data bus.
The CPU that the high speed mould is gone into module does not adopt the conventional one-piece machine, but realize with high speed CPLD (ComplexProgrammable Logic Device), thereby avoid the bottleneck that brings slowly by conventional one-piece machine response speed, every high speed acquisition module can be gathered 12 road signals, be divided into two groups, wherein the 1st to the 6th passage is one group, and the 7th to the 12nd passage is another group, and these two groups can connect same class sensor signal and also can connect two kinds of dissimilar sensor signals.Configurable 7 high speed moulds are gone into module at most on mainframe box, totally 84 road acquisition channels.
The key signal module is managed and is controlled by high speed CPLD, has following function:
1. key signal is handled: the key signal that sensor is sent here is nursed one's health, and one the tunnel send AD to gather, and another road changes into effective digit pulse, and every key signal module can be handled 4 road key signals;
2. 8 the road leave;
3. 8 the tunnel open into.
