Description
Technical field
The present invention relates to a kind of data managing method and system.
Background technology
At present, in smart machine, digital independent and unloading of the management module to modules, the most common are serial communication
With dual port RAM.
Serial communication uses a data line, and ground of data one is transmitted successively, and each data occupies one admittedly
Fixed time span.It only needs to several lines can just exchange information between system.This communication modes speed is slower,
When the module of management module CPU processing is more, it will take the plenty of time, cause plant running performance significantly to decline.And
When module is more in smart machine, the few advantage of which line has not existed yet.
Dual port RAM is that have two sets of completely self-contained data wires, address wire and Read-write Catrol in a SRAM memory
Line, and allow access of two independent systems simultaneously to memory progress randomness, i.e., shared multiport memory.But
It is due to that dual port RAM only has two ports, therefore the communication being only applicable between two modules.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the invention provides a kind of data managing method and system, abandon

Receive pending gathered data of the smart machine by bus transfer；
The pending gathered data is periodically read from data acquisition module by data management module, to described
Pending gathered data is handled；
By treated acquired data storage into data memory module；
Treated gathered data is shown by LCD MODULE.
Further, it is described to distribute data management mould to data management module, data memory module and LCD MODULE
In the chip select address step of block, the high address of data management module is converted to by chip selection signal by address decoder, passed through
Chip selection signal is connected with data management module, data memory module and LCD MODULE, complete paired data management module, data
The addressing of memory module and LCD MODULE.
Further, it is described to receive in the pending gathered data step that smart machine passes through bus transfer, intelligently set
It is standby that pending gathered data is periodically write into the data buffer zone of data acquisition module.
Further, it is described by treated gathered data by LCD MODULE step display, passing through data
The chip selection signal of management module, in the way of addressing, directly writes control command to LCD MODULE.
Further, in addition to：The chip select address of data management module is distributed key-press module, it is real-time by key-press module
Read the state of 8 buttons.
Further, in addition to：The chip select address of data management module is distributed indicating lamp module, passes through indicating lamp module
Control the state of 8 LED lights.
A kind of system for implementing data managing method, including：Data management module and multiple controlled modules, the data pipe
Reason module is connected by bus with each controlled module, and the quantity of the controlled module depends on data management module high address
The chip selection signal quantity exported by decoder.
Further, the controlled module includes data acquisition module, data memory module and LCD MODULE, described
Data acquisition module, for receiving pending gathered data of the smart machine by bus transfer；The data memory module,
For by acquired data storage in corresponding storage region；The LCD MODULE, for showing gathered data.
Further, the controlled module also includes key-press module, and the key-press module is used to read key value.
Further, the controlled module also includes indicating lamp module, and the indicating lamp module is used to control indicator lamp bright
Go out.
Compared with prior art, the beneficial effects of the invention are as follows：
(1) present invention has abandoned serial ports and has used bus to reach quick purpose, and dual port RAM is breached again and is only applicable to
Limitation between two systems, by reading and writing data of the data management module to each controlled module buffering area, completes intermodule
Data exchange, solve smart machine in data management module it is longer to the time shared by the data management and unloading of modules
The problem of, the operational efficiency of smart machine data management module is improved, increases the operation stability of smart machine, and realizes number
Management according to management module to multiple modules；
(2) present invention may be directly applied in the hardware development of commercial plant, especially possess multiple independences inside device
Module, in the case that intermodule possesses periodic reading and writing data and exchanged, can reduce data management module CPU due to data
Read-write and the time shared by unloading, release data management module CPU holding time.
