Abstract

The utility model provides meters and devices applying mechanical counters with a far distance displaying data device, which is composed of a mechanical sensor, an operation board, a keyboard, a display screen, a power supply, etc. The display on the liquid crystal display screen changes synchronously with the increase of data of a mechanical counter. With a simple structure, the utility model can be widely used in meters and devices for industry, agriculture and civil use, indicating the far distance monitoring and collection of data.

Description

Far distance displaying device of mechanical counter

The utility model belongs to a kind of data presentation device, particularly the remote demonstration of mechanical counter designation data.

Existing equipment and the measuring instrument that uses the mechanical counter video data, as: gas meter, water meter, ammeter etc. all disperse to be installed in each field of employment, and image data is promptly checked meter and must be carried out with installing to each.If the user is for the resident then will come off duty the user and check meter during being in, user and managerial personnel are all inconvenient.There is the people to design relative assembly in recent years for this reason, for example: Chinese patent 871041340.0,90204864.3,90223666.0 etc. but all belong to computer generalization and adopt auspicious processing, cost height, complex structure, need professional's operation, be not easy to penetration and promotion.

The utility model purpose is to provide a kind of equipment of mechanical counter designation data and the remote demonstration and pick-up unit of instrument of being applicable to easy to use simple in structure for society.

The utility model is realized by following scheme: install at the gear place that drives the digital piece of mechanical counter last position number by dynamic/static contact and constitute and sealed hold-down support is fixed in the sensor of meter case, connect the display device that remote outer operation board, keyboard, display screen and power supply constitutes by lead.Mechanical pick-up device reaches in the gear of mechanical counter end position, just stirs contact when rotating a tooth with gear and contacts static contact and do not influence gear and rotate and be advisable.Gear rotates electric signal of tooth circuit connection and passes to operation board by lead like this, and operation board once adds " 1 " computing, on the LCDs that its result is presented at operation board is connected, thus the remote demonstration of realization mechanical counter.Many display device are installed together can carry out data centralization demonstration and monitoring.

The moving contact of mechanical pick-up device of the present utility model is made with softer and whippy material, keyboard is by button, wiring board and output plug constitute, button comprises ten key, insert key and reset key totally 12 keys, it is unified mutually with the counter designation data to insert keyboard adjustment display screen video data before keyboard jack is used to bring into operation, operation board is by the COMS integrated circuit, diode, resistor, capacitor, having that wiring board constitutes connects the computing circuit that adds function, display screen is a LCD, power supply is the 1.5V direct supply, operation board, keyboard jack, display screen, power pack is dressed up one.

The utility model has guaranteed that with mechanical pick-up device concatenation operation plate mechanical counter and display screen video data are synchronous, has realized the remote demonstration of mechanical counter video data, and is simple in structure, price is low, be convenient to operation, is widely used.

Below in conjunction with at a distance the be shown as example of accompanying drawing the utility model is further described with gas meter.

Figure one is a functional-block diagram of the present utility model.

Figure two is the structural representation of mechanical pick-up device.

1 is that gas meter counter gear, 2 is that sensor dynamic/static contact, 3 is that fixing seal bearing, 4 is that lead, 5 is that operation board, 6 is that power supply, 7 is that keyboard jack, 8 is that keyboard, 9 is that LCDs, 10 is a gas meter in the drawings.

Softer and have enough flexible dynamic/static contact 2 to change system into by fixing seal bearing 3 to be fixed on the housing of gas meter 10 counters with the contact of miniature relay, it is the optimum position that the moving contact installation site has stirred just with the moving tooth of counter last digit transmission gear 1 revolution that moving contact contacts with static contact and do not influence that gear is rotated further, electric current passes to the totalizer operation board 5 that is made of CMOS integrated circuit, diode, resistor, capacitor, wiring board by lead 4 during contact closure, and operation board drives position, display screen 9 designation numbers end and adds " 1 ".Earlier keyboard 8 being inserted keyboard jack 7 during operation connects with operation board, press and extract keyboard after keyboard makes LCDs 9 display digits identical with gas meter 10 mechanical counter display digits, at this moment when using coal gas, the user rotates along with the gas meter counter gear, timer number piece video data and LCDs video data increase synchronously, have realized the remote demonstration of mechanical counter.Adopt this display to be installed in concentrated collection and monitoring that same position has just been realized data as the some gas meters in same seat building.
