Abstract
A centralized automatic recored system of meter's values with computer is suitable for gas, natural gas and electric power supply systems, and is a network system composed of host, user extensions, user meters and connecting cables. The serial port of computer is connected to the serial port of host in the record system for controlling the latter, resulting in computerized automatic record for different meters. If the serial port of host is connected to serial port of modem, the metropolitan area network can be used to realize remote communication and the automatic record system can be used for whole city.
Description
The present invention relates to a kind of computing machine and concentrate Automatic meter reading system, the computing machine that belongs to gauging tables such as coal gas, rock gas and Utilities Electric Co. is concentrated automatic meter number recorder.
At present, coal gas, rock gas and Utilities Electric Co. etc. all adopt the manual metering mode to copy and take family use data, are promptly copied to get by family to user family by the professional and use data in every month, as the charge foundation.So not only time-consuming but also effort, the user stays out when often occurring checking meter, and copies the complete not to the utmost situation of fetching data, and constantly build the urban skyscraper in addition, and inhabitation personnel mix, the also difficulty more just of work of checking meter.
Low in order to solve manual metering efficient, labour intensity is big, and when checking meter to problems such as the user make troubles, native system is that the subscriber's meter with some is unified into a network system, utilize computing machine to carry out centralized automatic meter-reading and centralized management, set up regional automatic meter reading system, by the city local network several regions automatic meter reading system is linked up, thereby further realize city networking centralized automatic meter-reading and computing machine centralized management, set up the scientific and effective modern times of cover with this and check meter and the toll administration system.
Above-mentioned purpose is achieved in that in former table mechanical counter and installs a reading device additional, electronic counter input end in its extension line subscriber's extension station other with being installed on gas meter, flow meter links to each other, with the I/O end parallel connection of two core cable with each extension set, link to each other with the I/O end of main frame again, the serial port of computing machine links to each other with the main frame serial port of checking meter, and the main frame of checking meter, computing machine enter city's telephone network through the modulator-demodular unit connection respectively.Reading device is the duplex magnetic induction switch, and subscriber's extension station is made up of the CMOS integrated circuit, comprises counting, code identification, pulse generation, input/output circuitry and internal cell.The main frame of checking meter adopts one-chip computer, is provided with RS-232 interface and is connected with computing machine.The modulator-demodular unit serial port links to each other with the main frame serial port of checking meter.
Native system utilizes computing machine as sending and receiving control and data processing, with the modern electronic technology is means, realized that the combustion gas user concentrates automatic data logging and the centralized management of counting cost by gas meter computing machine, have and check meter rapidly accurately, time saving and energy saving, safe and reliable, advantage such as easy and simple to handle, average each household is copied the time of getting only needed for 1.5 seconds, compare with traditional manual metering, improved work efficiency greatly, alleviated labour intensity, can not produce a bit inconvenience to user's usefulness gas yet, avoid the interference of registering one's residence and bringing to the user when checking meter.
Below in conjunction with accompanying drawing one embodiment of the present of invention are described in further detail.

Fig. 2 is regional automatic meter reading system connection layout
Fig. 3 is city networking automatic meter reading system connection layout
Fig. 4 is host circuit figure
Fig. 5 is the extension set circuit diagram
Computing machine is concentrated Automatic meter reading system, comprises former table counter, and the main frame of checking meter, subscriber's extension station, computing machine install a reading device 2 additional in former table mechanical counter 1, and it is welded on the ganged switch S that forms on the printed circuit board (PCB) by two tongue tubes
1, the electronic counter input end (CN of the subscriber's extension station 3 that its three extension lines are other with being installed on gas meter, flow meter
2) link to each other, 1/10th of mechanical counter are rotated a week, advance one to its position, simultaneously S
1Also one of the progression of closed the unlatching once, electronic counter has realized that electronic counter and subscriber's meter count synchronously.With the I/O end (CN of two core cable 4 with each extension set 3
1) parallel connection, again with the I/O end (CZ of main frame 5
1) link to each other, form a regional centralized kilowatt meter reading-out system (XT), promptly all extension sets 3 are charged after main frame 5 inserts energising, when checking meter with computing machine 6 serial ports and the main frame 5 serial port (CZ that check meter
2) link to each other, utilize the computer control main frame, after input is desired to plagiarize the organization at family etc. related parameter is arranged, main frame 5 promptly enters the automatic data logging state, main frame reads in recorded data in each extension set main frame and sends computing machine 6 to automatically, computing machine carries out various calculation process after receiving data, shows and printing relevant data and data.If main frame (5) serial port CZ2 is linked to each other with modulator-demodular unit (7) serial port, utilize city telephone network (8) just can with the computer realization telecommunication, computing machine can be controlled the main frame in a distant place in machine room, finish that copying of relative users gas consumption got and, set up several regional networks (XT) and just formed city networking automatic meter reading system the statistical computation work that various data are carried out.The main frame 5 of checking meter adopts one-chip computer, is provided with multiple meter reading method.When independent use, after can copying the work of getting to a plurality of systems continuously, again data are sent to computing machine 6, main frame 5 is provided with RS-232 interface with the computing machine communication, can directly be connected with computing machine 6, utilizes the computer control host work, by modulator-demodular unit (7) be MODEM can also with the computer realization telecommunication, host panel is provided with display window, and by its monitor host working condition, a main frame can drive 2048 extension sets.Subscriber's extension station 3 mainly is made up of the CMOS integrated circuit, comprising counting, code identification, pulse generation, imput output circuit and internal cell B
1Deng, Overall Power Consumption is very little, but only by internal cell power supply continuous working up to ten thousand hours.
According to design concept, actual fabrication two main frames and 100 extension sets, carried out installing experiment in Jiangjin, Sichuan Province city natural gas companies, through trimestral actual motion, the numeral of computing machine being copied the data of getting and natural gas meter mechanical counter record contrasts, and its numerical value is in full accord.
