The utility model adopts the technical scheme that the remote electric energy meter detection system comprises at least two electric energy meter detection devices and is characterized in that each electric energy meter detection device is equipped with an RS232 conversion module and performs the data transmission with the computer in the detection center after being switched in the Ethernet through the module, so that the computer can realize the remote control to each electric energy meter detection device.
Description
Technical field
The utility model relates to a kind of calibrating installation of electric energy meter, the remote power table verification system of especially utilizing Ethernet to form as telecommunication media.
Background technology
The pattern that domestic present calibrating department carries out electric energy meter calibration work is that a computing machine is by calibrating installation of a RS232 connection control, by the calibrating of testing person's operating computer realization to electric energy meter, the proportionate relationship of testing person, computing machine and calibrating installation is 1:1:1.
There is following shortcoming in this kind pattern: (1) antijamming capability is relatively poor; External interference is superimposed on the signal ground easily, and causing receiving terminal to disturb increases; (2) transmission range is relatively short (not by MODEM distance＜30m); For guaranteeing reliability of data communication, computing machine can not be away from calibrating installation; (3) communication speed is relatively slow
(115.2kbps); (4) computing machine carries the RS232 port and generally has only one, if Other Instruments equipment need use the RS232 port, must expand the computer motherboard function, increases the RS232 port, and the expansion limited amount.
Along with the increase year by year of electric energy meter calibration amount, calibrating installation is also corresponding to be increased, and require the electric energy meter calibration personnel can control many calibrating installations simultaneously at work, and the aforementioned techniques shortcoming has restricted this requirement.
The utility model content
Technical problem to be solved in the utility model is to overcome the shortcoming that exists in the above-mentioned background technology, a kind of electric energy meter detecting system is provided, this system should enough computer remote operations control many electric energy meter calibrating apparatus, have high efficiency, utilization of area rate height, reduce the characteristics of operating cost.
The utility model has adopted following technical scheme:
Remote power table verification system, comprise at least two electric energy meter calibrating apparatus, it is characterized in that every electric energy meter calibrating apparatus all disposes a RS232 modular converter, and by behind this module access network based on ethernet with the calibrating center computing machine carry out data transmission so that computer realization is to every electric energy meter calibrating apparatus Long-distance Control.
The computing machine that RS232 serial ports on described every electric energy meter calibrating apparatus is connected behind RS232 modular converter, Ethernet and the hub successively with the calibrating center carries out data transmission.
Described every electric energy meter calibrating apparatus also disposes a display terminal.
Use of the present utility model is: do relevant the setting earlier on computers, the electric energy meter calibrating apparatus of being connected is modeled as the network equipment; Then electric energy meter to be examined and determine is loaded onto calibrating installation, by computing machine successively by connecting the RS232 modular converter on the calibrating installation behind the hub, Ethernet, calibrating installation is directly controlled, carried out every performance calibrating, and carry out two-way data and transmit electric energy meter; Realized the long-range calibrating of electric energy meter thus.
The beneficial effects of the utility model: (1) electric energy meter calibration personnel uses a calculating function to control many calibrating installations simultaneously, calibration operation efficient is significantly improved, and need not to increase calibrating place and testing person, operating cost also is able to obvious reduction; (2) Ethernet is fit to telecommunication, the testing person can control remote calibration equipment by computer remote, perhaps can set up a central control room, master control computer of outfit just can be controlled all electric energy meter calibrating apparatus away from central control room in central control room, monitors all the electric energy meter calibration situations above the calibrating installation simultaneously.(3) owing to can fast, accurately carry computer commands and the every error information that receives electronic electric energy meter, and and electric energy meter calibrating apparatus has been realized control more reasonable, science.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Remote power table verification system, comprise at least two electric energy meter calibrating apparatus, it is characterized in that each electric energy meter calibrating apparatus 5 all disposes a RS232 modular converter 4, and carry out data transmission by the computing machines 1 at this module access network based on ethernet 3 backs and calibrating center, so that computer realization is to every electric energy meter calibrating apparatus Long-distance Control.
The computing machine that RS232 serial ports on described each electric energy meter calibrating apparatus is connected RS232 modular converter, Ethernet 3 and hub 2 backs and calibrating center successively carries out data transmission.
Described each electric energy meter calibrating apparatus also disposes a display terminal 6.
The utility model technology Network Based makes that the RS232 serial ports on every electric energy meter calibrating apparatus is examined and determine the computing machine at center by the long-range connection of Ethernet, thereby realizes the data transmission and the control of networking.Like this,, realize the electric energy meter calibrating apparatus more than 2 is controlled and operated by network, realize the telecommunication network centralized control with a computing machine by the function of access to netwoks.
Main control computer uses a unification control platform program, and each calibrating installation is all separate; Can start and stop the program of some calibrating installations arbitrarily, not influence the operation of other calibrating installation; Program is used unified calibrating control picture, shared scheme and database; An operator only needs just can control many electric energy meter calibrating apparatus to a main control computer operation; The field staff only need load and unload table, improves personnel and utilization of area efficient greatly, improves the work efficiency of system.
Can learn in the accompanying drawing that total system comprises many cover calibration equipments 7 (only showing 4 covers among the figure), every cover calibration equipment is made up of electric energy meter calibrating apparatus 5, display terminal 6 and RS232 modular converter 4; Wherein display terminal is a utility appliance.
1, computing machine also is provided with the page that a plurality of calibrating installations are monitored simultaneously when each calibrating installation being provided with a complete calibrating interface; In the verification process, the testing person can in time recognize the calibrating content that each calibrating installation is current by this interface.2, issue instructions to hub (HUB module) by computing machine earlier, hub is differentiated the RS232 modular converter that sends to each device to these instructions again, the RS232 modular converter is told device with instruction, allows device carry out calibration operation and the present duty of device also can occur at the interface of display terminal simultaneously.3, turn back on the control computer by same approach during from calibrating data that the electric energy meter of calibrating receives when calibrating installation.The testing person just can check the result of this project.
The equal buyable of above-described all components and parts.
