Abstract

The utility model relates to a telephone inquiry device for banks, which is composed of a power supply module, a CPU module, a telephone network module, a keyboard and display module, and an RS-232C interface. The telephone inquiry device for banks is connected by the RS-232C serial interface, runs under the host system of a bank, and is responsible for providing user data. An EDS host works under the control of a monitoring program, and is responsible for providing a telephone interface and providing phonetic real-time processing. The EDS device can not cause the potential threat of safety on the host of the bank. The utility model has high safety and less development capital.

Description

Telephone bank's query facility

The utility model relates to the telecommunication technology field, and particularly telephone bank's query facility (is called for short down: EDS equipment).It is made up of bank main and the query facility hardware two large divisions of telephone bank.

Known phone bank is that the user gets in touch by phone and bank, and bank provides for information about to the user by telephone answering.At present, mainly be to realize by " telephone sound card ", promptly be a sound card to be inserted in the bank main move, but have following deficiency: 1.. security is relatively poor.Hardware aspect, its bus directly links to each other with the bank main bus, as long as the hardware damage of sound card will directly have influence on bank main; The bank main operating system nucleus will be revised in the software aspect, and the mistake that design may exist will be brought potential prestige rib to the security of bank main system; 2.. because telephone wire from outdoor, is directly introduced the bank main system, when accident is met in outside line, just directly have influence on the safety of bank main system.3.. the host computer system expense is bigger, and all working is all finished by bank main, so can directly have influence on the normal operation of other softwares of bank main system.

The purpose of this utility model is intended to provide for bank a kind of telephone bank's inquiry system of safe and reliable phone auto answer.This EDS system hardware and bank main are not contacted directly, and only as a kind of non-standard plug-in device of bank main system, just link to each other with main frame by standard RS-232C interface; Host operating system need not revised by its function software, can not cause potential prestige rib to bank main, and main true-time operation is finished by the EDS main frame, and security is good.

The purpose of this utility model is finished like this:

Fig. 1 is this practical structure block diagram.

This device structure is represented with embodiment such as Fig. 1: EDS equipment is by LM7805, LM7812, LM7912 three terminal regulator power module, 8098 microprocessor CPU modules of Intel Company, LM324 operational amplifier telephone network module, CD4051, LM386 and MT8870 chip are monitored control module, a slice 74HC273 keyboard and display module and RS-232C interface are formed, wherein the CPU module comprises watchdog routine, data-storing district two parts, the CPU module is connected each module by data bus with control bus, EDS equipment and bank main connect and compose with the RS-232C serial line interface.

Its enforcement is that equipment moves under the bank main system, and providing of user data is provided; The EDS main frame is the plug-in device that is independent of the bank main system, carries out work under the control of watchdog routine, is responsible for telephony interface and the real-time processing of voice is provided; Power module converts the 220V civil power to EDS main frame required various voltages; Telephone network module (be passage or port, an EDS main frame can connect four telephone network modules at most) receives and process user is called out, and converts the digital signal that CPU produces to the voice loopback to the user; Keyboard and display module, reset the monitoring of control EDS main frame, and the real-time working state of EDS is shown.During work, after the user puts through the EDS main frame by ordinary telephone set, by the calling of EDS listening user, and prompting user operation, user's all operations is received by EDS and system operating software is given in loopback, and system operating software is made explanations, the result is carried out by EDS, changes into voice and gives the user.

Claims

A kind of telephone bank query facility, comprise bank main and EDS equipment, it is characterized in that EDS equipment is by LM7805, LM7812, LM7912 three terminal regulator power module, 8098 microprocessor CPU modules of Intel Company, LM324 operational amplifier telephone network module, CD4051, LM386 and MT8870 chip are monitored control module, a slice 74HC273 keyboard and display module and RS-232C interface are formed, wherein the CPU module comprises watchdog routine, data-storing district two parts, the CPU module is connected each module by data bus with control bus, EDS equipment and bank main connect and compose with the RS-232C serial line interface.
