Abstract

The remote meter reading transcriber is used for account computer to transcrib the reading in water, watt-hour or gas meter remotely through telephone line, power line, cable, radio, etc. It consists of special microcomputer comprising bar code recognizer, monochip computer, modem and other circuit and mounted inside the meter and several character wheels with bar codes. The present invention solves the problems of remote meter reading transcription and peak-valley time-sharing fee, and it may be widely used.

Description

A kind of remote meter reading device

The utility model relates to office automation, is mainly used in the clearing of carrying out expenses such as water, electricity, coal gas between companies such as water, electricity, coal gas and its user.

At present, carry out the clearing of expenses such as water, electricity, coal gas between company such as water, electricity, coal gas and its user, generally take by the staff of companies such as water, electricity, coal gas regularly (being generally one month) copy from house to house and get the corresponding measurement meter reading and collect corresponding fund or go up the way that corresponding company pays in by the user and finish.This way is changed mutually with the office automation process of advancing by leaps and bounds, and seems to fall behind with original like that.

Target of the present utility model is: design a kind of staff's walking that can replace companies such as water, electricity, coal gas, check meter, whole hand labors and can realize peak, paddy time-shared charge, e-seals is installed, water, electricity, coal gas source is implemented the remote meter reading device of function such as remote-control cut-off such as the last company of user pays in.

The utility model by screen bar code recognizer, single-chip microcomputer (or single-chip microcomputer, programmable timer), modulator-demodular unit (or double-tone transceiver) frequently wait that circuit is formed, be installed in special-purpose micro computer on the gauging table character wheel frame and several are distributed with the character wheel formation that some groups of polychrome bar codes of corresponding relation are arranged with reading on its garden side face.(as shown in Figure 1, 2, 3)

The utility model is because technology such as active adoption computers, communication, electronics, and it is compared with depending merely on the conventional art that gauging table manually settles accounts, and produced qualitative leap.Be in particular in: 1. owing to after using this device, neither go from house to house to check meter with the staff, the companies such as water, electricity, coal gas of also going up without the user pay in, and it provides unique user of making and each company all satisfied clearing way.2. the utility model can make full use of the potentiality of existing utility (as telephone network, power network, clearing computing machine etc.), under the situation that drops into a small amount of fund (being used to make the utility model), and the expense and the time of having saved a large amount of hand labors.

3. the utility model can carry out peak, paddy time-shared charge to water, electricity, coal gas etc., guides people to avoid the peak period with economic leverage as far as possible and makes narrow resources such as water, electricity, coal gas.4. the utility model is installed e-seals to gauging table or batch meter, but so that write down split vestige and Realtime Alerts, takes precautions against stealing, water, the behavior of robber's gas steathily effectively.The utility model can to unreasonablely refuse to pay expense such as water, electricity, coal gas or stealings, steal water, the gas-thief implements the sanction in remote-control cut-off water, electricity, coal gas source, makes the management of government utility that initiative more be arranged.6. the utility model is for the Push Technology progress, and it is significant to build intelligent building.

Fig. 1 is special-purpose micro computer internal circuit configuration figure of the present utility model.

Fig. 2 is the front view of the utility model in gauging tables such as water, electricity, coal gas.

Fig. 3 is the right cut-open view of the utility model in gauging tables such as water, electricity, coal gas.

Best implementation of the present utility model as shown in Figure 1, 2, 3.Clearing computing machine regularly (being generally one month) passes through telephone wire, line of electric force, cable (closed-circuit television cable etc.).The wireless communication modes that waits is connected special-purpose micro computer A of the present utility model, after special-purpose micro computer A receives the order of checking meter, read character wheel B and go up with reading and the bar code of corresponding relation is arranged (during the employing time-shared charge by giving programming control screen bar code recognizer by its inner single-chip microcomputer (can select 8031 for use), regularly start single-chip microcomputer by programmable timer and finish above process), and successively several variable codes are sent to the clearing computing machine after the modulator-demodular unit modulation after being converted into corresponding variable.Transmission finish treat special-purpose micro computer A receive promptly disconnect after the clearing computing machine out-of-work order with the clearing computing machine get in touch the reinstatement attitude.The variable that reads for making is reliable, and the bar code that distributes on the side face of character wheel B garden has adopted special construction (shown in Fig. 2,3), and is at first corresponding with ten readings of 0-9, character wheel garden week is divided into ten five equilibriums, the heart angle, garden of every five equilibrium is 36 °, and then every five equilibrium is divided into three groups, 12 ° every group.Like this, character wheel garden side face is divided into 30 groups, and these 30 groups are printed on 30 groups of different bar codes.Every group of bar code is by silver (in vain) vitta 1 and 0 two kinds of bar code combinations of black bar totally five formations.This special construction can be eliminated various sum of errors low level character wheels and high-order character wheel issuable misreading when carry effectively.Screen bar code recognizer can be made of the photoelectricity recognition unit of (the recessed integrated circuit basal plane of phototriode can't receive light emitting diode [or laser diode] so that guarantee phototriode can only receive character wheel garden side face bar code reflected light direct light) light emitting diode (or laser diode) C and phototriode D and form.Because every group of bar code be five, five photoelectricity recognition units are also arranged so five bar codes of screen bar code recognizer and this are corresponding.To each photoelectricity recognition unit, silver (in vain) vitta and black bar are easy to discern, and screen bar code recognizer is discerned be under it one group totally five bar codes, just can reach the purpose that reads the character wheel reading.Certainly, screen bar code recognizer also can adopt other structure, as scan-type, infrared electro tubular type, even also silver (in vain) vitta can be coated fluorescent powder and is adopted phototriode tubular type etc., adopt which kind of structure actually, be necessary to take into account two factors of reliability and cost and determine.The quantity of screen bar code recognizer is determined by the character wheel number.In the appropriate location of gauging table or batch meter several pressure sensitive switch are installed and single-chip microcomputer links, just can be constituted e-seals.In the backward channel of single-chip microcomputer, increase the just remote-controlled cut-out water of servo control mechanism, electricity, the coal gas source of driving.These functions all can increase and decrease according to actual needs.

Claims

1. a remote meter reading device is made up of special-purpose micro computer and several character wheels.It is characterized in that:

Screen bar code recognizer in the special-purpose micro computer and on its garden side face, be distributed with the data acquisition system (DAS) that has the character wheel of some groups of polychrome bar codes of corresponding relation to constitute with reading.

2. remote meter reading device as claimed in claim 1 is characterized in that: in the special-purpose micro computer modulator-demodular unit is arranged.
