Abstract

The utility model relates to an outdoor video centralized meter reading and inspecting device which includes reflection-type video acquisition terminals, four-core wires used for signal transmission, a bus protective concentrator, and a hand-held metering reading machine. The device is characterized in that various household video acquisition terminal users are connected with the bus protective concentrator via four-core buses; during the meter reading, the buses are connected with the hand-held meter-reading device for the data reading, the shooting, or the video recording of corresponding users; and then the data is transmitted to a computer for batch processing; and when the meter reading is not carried out, the buses can be converted into the ground state. The reading of the device is accurate and visual.

Description

Outdoor video centralized automatic meter-reading and checking device

Technical field

The utility model patent is a kind of table tool reading outdoor video acquisition technique, through this technology, but can common gauge table directly be transformed into remote meter reading, can improve the efficient of checking meter in the scene greatly.

Background technology

Along with people's is for the attention of secret protection, the rising of personnel's wage, and the more and more difficult of registering one's residence and checking meter and becoming, required expense is increasingly high, and carrying out that the open air far copies is one of solution.It basically all is through partly installing data acquisition module additional in the inside counting of table tool that equipment is far copied in present general open air; Carry out the open air and far copy, like photo-electronic directly reading table, pulse collection mode or the like, but these modes all need be integrated into data acquisition module in the table; And output is a numerical value just; Not directly perceived, if error in data can't judge out of doors, can only register one's residence and check and can confirm with the base table reading.Can not observe table tool real-time operational situation, more complicated because of the table structure of signing an undertaking, increased failure rate, in case certain part goes wrong, must change the monoblock table, so later maintenance cost is all than higher.

Also have at present the design of far checking meter of some shooting direct-reading, but generally be to adopt directly to take digital card, transmit picture signal then and handle to meter reader, as adopting the video transmission mode, need to adopt special video transmission line, cost is higher.

The existing technology that also exists the employing image capture module to carry out image transmission meter reading all be to adopt directly fixing and the dial plate top, and some table tool character wheel figure place all has 6 to 8; Because of the cam lens visual angle and the distance limit; Only read wherein several bit data, or just need select the high wide-angle lens of price for use, it is a lot of perhaps to let camera exceed dial plate; Neither attractive in appearance, also be easily damaged.

Summary of the invention

The present invention is directed to the weak point of existing product, designed new open air collection and copied checking device, purpose is: for indoor table tool or other are difficult to copy the copying and accepting of table tool of seeing low-cost solution is provided.Directly can be through reflective video acquisition output through the vision signal of ordinary telephone line transmission with dial plate information, and can carry out the live video shooting and record, greatly reduce the difficulty and the cost of system's installation and maintenance.

Because of can checking the complete information of dial plate data out of doors, see the table tool situation of walking about intuitively, utilize this system also easily to carry out the inspection that the user uses.

Technical solution of the present invention:

A kind of outdoor video centralized automatic meter-reading checking device; The four-core electric wire that comprises reflective video acquisition terminal, transmission signals; The bus protection concentrator, hand-held meter reader is characterized in that: through the four-core bus each home videos acquisition terminal user is connected in the bus protection concentrator; Can bus be connected to hand-held kilowatt meter recorder when checking meter; The data of carrying out relative users read, take pictures or video record, reach computer then and carry out batch process, can be exchanged into ground state at the non-Time BUS of checking meter.

Said reflective video acquisition terminal comprises image capture module and control module; The collection of image is the camera lens that dial plate information is reflexed to image capture module through minute surface or prism; Control module is according to the signal that receives; The work of control image capture module, image capture module carries out the image of transparent reflector reflection to be transferred to handheld device after the mirror image conversion.

The camera lens of said image capture module is positioned at and the dial plate parallel position, adopts the concavees lens form on the translucent cover before the camera lens.

Said image capture module band LED lamp can be opened light filling under the situation of insufficient light, the switch of LED lamp and brightness regulation can be by the hand-held set Long-distance Control.

In the said bus protection concentrator change over switch is arranged.

The beneficial effect of this utility model:

1, accuracy of reading is directly perceived.Be equivalent to human eye Direct observation dial plate, very directly perceived, the error problem that exists in not having other conversion of signals and transmitting; Can see the situation of walking about of all character wheels; Utilize this characteristics, as be used on the indoor gas table, the great convenience gas company carries out the user and measures inspection.

2, efficient is high.With respect to other image or video meter copying device,, improved on-the-spot efficient of checking meter greatly because after can adopting on-the-spot recorded video or photographic images, the company import system of getting back to focuses on.

3, cost is low, because only need video acquisition device, bus adopts common four-core telephone wire, anti-thunderbolt, simple and effective anti-thunderbolt, the design of tamper-proof concentrator, and the mode of far copying with respect to other greatly reduces use cost.Difficulty and the expense safeguarded have also been reduced.
