Abstract
A kind of new telephone charge counter is made up of chip microprocessor, status scan circuit, voice-frequency dialing receiving circuit, pulse dialing receiving circuit, data storage circuitry, display circuit, power supply and charging circuit, transceive data circuit etc.Owing to adopted the transceive data circuit, so can receive the change data message that Local Exchange sends and return handshaking information and receive information such as reliable, be linked to be a communication system with Local Exchange, thereby the modification rate and the modification that are convenient to the public telephone counting equipment are provided with parameter.The present invention is not only applicable to program control office, is applicable to office in length and breadth yet, can be widely used in the requirement that city's public telephone at county level charges.
Description
The present invention relates to a kind of taximeter, particularly a kind of new telephone charge counter.
Present public telephone taximeter, common have two kinds of forms, and a kind of taximeter is called count table, is by receiving 12KC or the 16KC metering pulse signal that Local Exchange sends, carrying out multi-metering.Advantage is that circuit is simple, and all rates are revised, as long as city office machine room, metering pulse equipment reprogramming to 12KC or 16KC, then the citywide taximeter just can be synchronous with city office automatically, do not need the user's modification taximeter, and shortcoming is owing to the capacity limit that is subjected to the metering pulse equipment of the 12KC of city office or 16, this taximeter installed capacity is restricted, can not satisfies the needs of present public telephone development far away.In addition, such taximeter can only be to the local telephone network multi-metering, and can not carry out the world, national distance charges.Second kind is taximeter, and such taximeter generally all by microprocessor or Single-chip Controlling, and has memory, rate of storage.It is that according to the number that the user dials, analysis belongs to local telephone network national distance, international long-distance or local network etc., finds corresponding rate accounting then in internal memory by reception user's dialing information.Such taximeter advantage is that memory capacity is big, control flexiblely, can be suitable for the requirement that various local telephone networks, long-distance, local network, farm work, information station etc. charge, and directly perceived, the number of not only can explicit user dialling can also show call timers, area code, rate, total telephone expenses etc.Such taximeter shortcoming is to revise the rate difficulty, the more city of public telephone particularly, install such taximeter many after, all same problem can appear, each rate or increase area codes etc. revised all need the user to be with taximeter to public words class of local telephone network business office, and are very inconvenient.
The objective of the invention is to avoid above-mentioned the deficiencies in the prior art part and provide a kind of new telephone charge counter of convenience modification taximeter data.
Purpose of the present invention can reach by following measure: the present invention includes chip microprocessor, the status scan circuit, the voice-frequency dialing receiving circuit, the pulse dialing receiving circuit, data storage circuitry, display circuit, power supply and charging circuit, it is characterized in that: also have the transceive data circuit, chip microprocessor links to each other with the status scan circuit, the off-hook of monitoring telephone, the break-make of hook state and circuit and antipole state, link to each other with the voice-frequency dialing receiving circuit, receive user's DTMF pulsing signal, link to each other with the pulse dialing receiving circuit, receive user's pulse dialing information, link to each other according to circuit with the transmitting-receiving amount of money, receive the change data message that Local Exchange sends and return handshaking information and receive authentic communication and Local Exchange is linked to be a communication system, link to each other with display circuit, the explicit user dialing information, area code, rate, state, the telephone expenses amount of money, accumulative total information, link to each other with data storage circuitry, deposit rate, cumulative data.
The present invention has following advantage compared to existing technology:
1. can realize metering and billing function to long-distance, local telephone network, farm work, local network etc., not be subjected to the capacity limit of Local Exchange's counting equipment, can increase public telephone quantity according to demand arbitrarily.
2. have and revise rate, area code, service charge performance easily, exempt Local Exchange when revising public words expenses standard at every turn or increasing new area code, require the user to tear the worry that machine changes chip open to public words class.
3. applicability is strong, is not only applicable to program control office, also is applicable to office in length and breadth, can be widely used in the requirement that city's public telephone at county level charges.
Fig. 1 is a functional-block diagram of the present invention.
The present invention is described in further detail below in conjunction with accompanying drawing (embodiment):
With reference to Fig. 1, the present invention is made up of monolithic microprocessor 1, status scan circuit 2, voice-frequency dialing receiving circuit 3, pulse dialing receiving circuit 4, data storage circuitry 5, display circuit 6, power supply and charging circuit 7, transceive data circuit 8 etc., 9 is local telephone in addition, and 10 is phone.
Behind user's off-hook, chip microprocessor is by after the status scan electric circuit inspection, start voice-frequency dialing receiving circuit and pulse dialing receiving circuit, receive after the number of user's dial-out, judge that type of call is local telephone network, long-distance call, farm work, local network etc., in the data storage circuit, find out rate then, go out corresponding telephone expenses according to the user's communication Time Calculation, show on display screen by display circuit, and in the accumulative total write memory circuit.When telephone expenses or area code need be revised by Local Exchange, revise machine by the microcomputer of Local Exchange or special-purpose rate, send dialing information and put through the public telephone station that taximeter is housed, to make amendment now after the rate with the voice prompt user, send a string modification password, return a string confirmation immediately after chip microprocessor in the taximeter is received this signal by the transceive data circuit, after Local Exchange receives the confirmation, the data that revise are sent and receive affirmation after withdraw from.And then send out logical another user work of making amendment of number exhaling.The microprocessor of taximeter receives the modification data and is placed in the data storage circuitry after treatment.Charge next time and then press the new standard execution.
If the transmission data are with double-tone frequency mode, then can save receiving unit in the transceive data circuit, data directly receive and deliver to chip microprocessor by double-tone frequency receiving circuit and handle.
The present invention has also adopted the power down protection technology, and the data power down can not lost.
