Abstract
The utility model disclose an intelligent gauge table data concentrator, which comprises a single chip micro-computer, wherein the single chip micro-computer is connected with a memory system, a clock system, a power system, a display system, a key board input system and an ascending-descending communication interface system. The intelligent gauge table data concentrator has the advantages of complete functions, convenient operation, visual display, flexible positioning, multiple interfaces, low cost, low power consumption and the like.
Description
Technical field
The utility model relates to data acquisition system (DAS), a kind of specifically intelligent meter data concentrator.
Background technology
The technology of intelligent meter tool data concentrator employing at present mainly contains two kinds: a kind of technology is to adopt small-sized industrial computer, and another kind of technology is to be processor with the single-chip microcomputer.The former programme convenience, construction cycle weak point, flexible configuration, powerful, memory data output is big, data are copied and accepted, are inquired about, statistics etc. is convenient, directly perceived, quick, but cost height, big, the working environment requirement height of power consumption, and most functions of industrial computer do not use, and cause the wasting of resources easily.Latter's cost is low, power consumption is little, the working environment requirement is low, but function singleness, on-keyboard and display screen can't be configured and check that external interface is few, versatility is poor, is only applicable to particular place.
The utility model content
The purpose of this utility model is for providing a kind of perfect in shape and function, intuitive display, interface various, intelligent meter data concentrator cheaply.
The intelligent meter data concentrator comprises single-chip microcomputer, and described single-chip microcomputer is connected with storage system, clock system, power-supply system, display system, key entry system and up-downgoing communication interface system.
Described uplink communication interface comprises RS232/485 interface and wireless module/GPRS module interface, and the downgoing communication interface comprises the RS485 interface.
Single-chip microcomputer is a key of the present utility model, controls the work of other several sections.Major function has: the input of response keyboard; Send, receive instruction and data; Regularly, check meter in real time; Storage, inquiring user consumption and configuration information; Control display screen output etc.
Key entry system is used to receive user's input information.According to user's selection function difference, to carry out operational factor, concentrator ID, concentrator time, timing meter reading mode, the supplier number which kind of operated-be provided with equipment by single-chip microcomputer decision and still revise password, single table is gathered still to concentrate and is gathered.
Display system is mainly used in information such as display device configuration, user's consumption, collection, communication state.
Power-supply system is total system power supply (comprising the front-end table tool).Power-supply system can use alternating current 220V or direct current 12V as its power supply.Power-supply system has one can keep 48 hours reserve battery of system works, and standby power supply and external power source automatically switch: when the externally fed interruption, system automatically switches to by reserve battery and powers; When the externally fed recovery, system automaticallyes switch back by externally fed.
Clock system provides temporal information (as copying and accepting the time) for whole data concentrator, and the user can pass through keyboard or host computer setting easily.
In the up-downgoing communication interface system, the uplink communication interface can with hand-held set, management host etc. by RS232/485 interface swap data (this equipment has been reserved wireless module/GPRS module interface, can communicate by letter with management host by wireless mode); The downgoing communication interface is by the direct acquisition tables tool of RS485 interface indicating value.
Storage system is mainly used in and preserves equipment disposition, user, consumption, checks meter, shows information such as tool state.The definition of the principle of design in data store organisation comparable data storehouse is so that fast updating, retrieval when moving in system.
The utility model is that core makes up hardware system with the single-chip microcomputer, not only can finish the function that small-sized industrial computer is realized, and overcome the defective of original two kinds of technology, make intelligent meter tool data concentrator possess characteristics such as perfect in shape and function, easy to operate, intuitive display, flexible configuration, interface are various, low-cost, low-power consumption.
Every intelligent meter tool data concentrator can be gathered 1024 table tool continuous datas, and data are handled, store, shown, and with meter-copy device or the communication of management main website etc.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As Fig. 1-shown in Figure 8, the intelligent meter data concentrator, comprise single-chip microcomputer, described single-chip microcomputer is connected with storage system, clock system, power-supply system, display system, key entry system and up-downgoing communication interface system, described uplink communication interface comprises RS232/485 interface and wireless module/GPRS module interface, and the downgoing communication interface comprises the RS485 interface.
The utility model can be according to the function of family number or current indicating value of Table I D question blank tool and consumption.Consider that Single Chip Microcomputer (SCM) program can not nesting allocation, internal memory is limited, and travelling speed is slow, can't locate the table tool information of being inquired about fast with general searching algorithm, two index areas have been opened up in storage system for this reason, single-chip microcomputer navigates to corresponding index area according to the key word of the inquiry difference that the user selects with record pointer, searches for fast in conjunction with the meta searching algorithm again; If this index area bar record and key word of the inquiry coupling, single-chip microcomputer is read this and is recorded in the data field relative address and record pointer is positioned this.
