Accompanying drawing explanation

Fig. 1 is circuit block diagram of the present utility model.

Embodiment

Below in conjunction with accompanying drawing, the utility model embodiment is further described.

A kind of IC-card prepaid watermeter data integrated reading device, as shown in Figure 1, comprise power management module and control circuit, control circuit is by single-chip microcomputer and peripheral circuit, storer, IC-card read-write interface, safety control module, RS232 communication interface, infrared communication interface, communication post circuit and alarm module composition.Power management module is connected with control circuit for control circuit power supply, single-chip microcomputer and peripheral circuit thereof are connected with alarm module with storer, IC-card read-write interface, safety control module, RS232 communication interface, infrared communication interface, communication post circuit, single chip machine controlling circuit is as the core of control circuit, its major function is unified command, the work of coordinating to control each interface circuit, module, to realize the function of this integrated reading device.Below each several part circuit and module in control circuit are described respectively:

Storer adopts EEPROM nonvolatile memory, and this storer is connected with single-chip microcomputer by bus interface.This storer comprises and monthly deposits in corridor all users' various information and data for storing, as user's water meter number of registration, the date of checking meter, surplus water, accumulative total Water usage, the overdraw water yield, this month Water usage, water meter duty etc.In these data and information Shi You building, each user is transferred in EEPROM by IC-card.

IC-card read-write interface is connected with single-chip microcomputer by STD bus with safety control module, and single-chip microcomputer is read the data on IC-card and these data are write in EEPROM by IC-card read-write interface and safety control module.When IC-card is inserted into IC-card seat (IC-card read-write interface) and puts in place, single-chip microcomputer powers to IC-card by bus, and by the sequential requirement of stipulating in ISO7816-3 international standard, to IC-card, provides clock order and data.Safety control module is a kind of secret microcontroller of smart card special use; data transmission is had and high security feature, and single-chip microcomputer is protected to, IC-card is carried out authentication, the data of input are decrypted and these data conversion storages are entered in EEPROM communication line by this safety control module.

In order to carry out data-transformation facility with external unit (handheld reading meter device), control circuit has been equipped with two communication interfaces: RS232 communication interface and infrared communication interface, RS232 communication interface is connected with microcontroller communication port and 9 core cable sockets of standard is provided, can complete the conversion of communication level between RS232 standard and TTL standard, by communication cable, be connected with external unit (handheld reading meter device), realize the communication between this integrated reading device and write by hand device.Infrared communication interface adopts irDA communication interface to be connected with microcontroller communication port, completes conversion between TTL fiduciary level and irDA-2 fiduciary level the infrared short-range data transfer function of realization and external unit (handheld reading meter device).Above-mentioned RS232 communication interface and infrared communication interface are linked the UART communication port line of single-chip microcomputer in "or" mode, external unit (handheld reading meter device) can select one of above-mentioned two kinds of communication modes and this integrated reading device to carry out data transmission.During communication, adopt agreement and the parameter of this integrated reading device and external unit (handheld reading meter device) agreement to carry out, handheld reading meter device first sends specified signal and wakes the single-chip microcomputer in power saving sleep state up by the communication post circuit in this integrated reading device, after single-chip microcomputer operation, be communication interface power supply, on communication port line, receive information and close unchecked that interface, according to the parameter of the write by hand device transfer data command of receiving, this integrated reading device sends to write by hand device by being stored in appointment month in EEPROM or the user data of several months of appointment.

Communication post circuit when externally equipment (handheld reading meter device) requires lower and the communication of this integrated reading device wakes single-chip microcomputer to carry out communication up from power saving sleep state.

The flicker of alarm module by LED light be, the ring of ring device is indicated duty and the prompting to maloperation of this integrated reading device, expression operation (Card Reader or communication) normal termination as bright in " PASS " pilot lamp; The illegal data that transmit of the bright expression of " unauthorized " pilot lamp user IC-card attempt; Data transmission between " communication is wrong " pilot lamp this integrated reading device of bright expression and write by hand device has produced verification mistake or other mistakes; The bright expression energy content of battery of " battery is low " pilot lamp is about to exhaust, and prompting should more renew battery etc.
