Abstract
The utility model relates to a counting video output unit for metering device, which belongs to electronic communication technology. The utility model is equipped with a camera head and a light filling lamp above the surface inside previous metering device. When the metering device is checked to record the data, an electrical source is opened through info, the lamp fills light and the camera head works, then the counting in the metering device can be exported truly. When the counting is made out, the electrical source is closed through info, the lamp is switched off, and the camera head ceases to work.
Description
The utility model belongs to the electronic communication technology field.
Present known teletransmission intelligent metering instrument such as water, electricity, gas table adopt the table counting to transmit according to process type mostly, promptly in measuring instrument, adorn photoelectricity, magnetoelectricity isopulse sensor or displacement electric resistance sensor, convert the counting of measuring instrument to electronic data output, this is to be the secondary counting of benchmark with the measuring instrument counting, but is not the slavish copying of measuring instrument counting.Owing to sensor errors produces the mete-wand variation, accumulation gets up to cause the secondary counting of output and measuring instrument counting not to be inconsistent.Simultaneously, sensor must have the uninterrupted power source power supply, and be subject to the interference of thunder and lightning, magnetic field, electric wave, power supply, power current, long-time continual in service, its characteristic electron may change at any time, the error of secondary counting generation is difficult to proofread and correct elimination in addition, and the stability of its work, accuracy, reliability are difficult to hold.
The purpose of this utility model provides measuring instrument counting video output device, and slavish copying measuring instrument counting is realized undistorted output.
The purpose of this utility model is achieved in that the surface in measuring instrument installs recording head and light filling lamp, need make an inventory the table counting according to the time, sender is opened power supply, supplement light when the light is on, recording head work, pickup surface counting, instantaneous transferring out.Make a copy of counting and finish, the sender power cutoff, lamp puts out, and recording head is not worked.So when needs are checked meter, send signal, can obtain the surface counting.
Owing to adopt such scheme, be characterized in: 1, the counting of video output is the slavish copying of measuring instrument counting forever, belongs to non-process type counting, does not exist secondary to count incident counting error; 2, only sender energising when needs are checked meter is not worked, not electricity consumption at ordinary times, and the instrument cost of use is humble; 3, recording head work is not subjected to the interference of external environment condition basically, can stablize for a long time, accurately, reliability service; 4, keep the measuring instrument structure constant, only the surface installs light filling lamp, recording head additional within it, and it is little to install expense additional.
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
Fig. 1 is the structural representation of the utility model embodiment.
Among Fig. 1, recording head (4), light filling lamp (3) are installed in the surface in measuring instrument lid (1), connect, and by outside connecing in the box, are connected with transmission network with video transmission line (5), power lead (6).When using the local telephone network netting twine, both can unify video transmission line (5) and power lead (6).Send signal when network, power supply is open-minded, and light filling lamp (3) is bright, recording head (4) work, instantaneous with the surface count reading device shown in data (2) export by transmission line (5).Counting reading device in surface can become row character code formula, also can be in groups the spinning roller formula or the pointer indicating type.The signal powered-down is sent in the end of checking meter, and light filling lamp (3), recording head (4) outage are not worked.
Claims (2)
1, measuring instrument counting video output device, be the surface in measuring instrument, feature is to install recording head and light filling lamp additional, the power lead of recording head and light filling lamp, the video transmission line of recording head, power lead and video transmission line are connected with transmission network by outside drawing in the table.
2, measuring instrument counting video output device according to claim 1 is characterized in that the power lead of recording head and light filling lamp, the video transmission line of recording head, and when using the local telephone network netting twine, both unite two into one.
