Abstract
The utility model relates to a radio with IC card, which is a radio capable of carrying out decryption by an IC card. The utility model is provided with an antenna, a high-frequency receiver, a demodulator, a power amplifier, a power supply, and a loudspeaker. The utility model is characterized in that the radio with IC card is also provided with a control CUP, an IC card, and a digital-analog converter D/A, wherein, the card is inserted in an inserting seat for the IC card, and the IC card is connected with a control processor CPU via a signal line; the digital-analog converter D/A is connected with the control processor CPU via the signal line. The radio device is provided with a working mode selecting switch K, and the working model selecting switch has a normal mode switch connection end and a decoding mode switch connection end.
Description
What the broadcast receiver of the utility model band IC-card related to is the broadcast receiver that a kind of available IC-card is decrypted broadcast message.
The information that existing Wireless-wire broadcasting is sent is public information, and common broadcast receiver all can receive, and can't select the recipient.
The purpose of this utility model is to provide a kind of broadcast receiver with IC-card at above-mentioned weak point, the broadcaster is selected the recipient, have only recipient just can receive for information about, can make the broadcaster utilize the present invention the recipient to be carried out activities such as scope qualification, content choice, charging like this through authorizing.
The broadcast receiver of band IC-card takes following scheme to realize: the broadcast receiver structure of band IC-card comprises antenna, high-frequency receiver, demodulator, mode of operation selector switch, processor controls CPU (central processing unit), IC-card, digital to analog converter D/A, power amplifier, loud speaker, power supply.The IC-card dress is inserted in the IC-card socket, links to each other with processor controls CPU by holding wire, and digital to analog converter D/A links to each other with processor controls CPU by holding wire, and the mode of operation selector switch has general mode, two groups of switches of decryption mode.Processor controls CPU, digital to analog converter D/A link to each other with the decryption mode switch of mode of operation selector switch by holding wire respectively.
When the broadcast receiver of band IC-card directly send power amplifier when demodulator output, be common broadcast receiver, can directly listen to common radio broadcasting, when receiving enciphered data broadcasting, the digital information of demodulator output is given processing such as IC-card is decrypted, authentication charging earlier by processor controls CPU (central processing unit) control.Data flow after the deciphering is given D/A and is reduced into audio signal, send the loud speaker sounding through power amplifier again, can receive ciphered data broadcasting.The broadcast receiver of band IC-card is reasonable in design, simple in structure, disclosed in the past broadcast mode is become both keep its high efficiency broadcast mode, can select the recipient again, have only recipient just can receive for information about through authorizing, make the broadcaster utilize the utility model the recipient to be carried out activities such as scope qualification, content choice, charging, making pre-payment listen to compensation becomes possibility.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is the broadcast receiver structure block diagram of band IC-card.
With reference to accompanying drawing, the broadcast receiver structure of band IC-card has antenna, high-frequency receiver, demodulator, mode of operation selector switch K, processor controls CPU (central processing unit), IC-card, digital to analog converter D/A, power amplifier, loud speaker, power supply.Radio devices has the IC-card socket, the IC-card dress is inserted in the IC-card socket, link to each other with processor controls CPU by holding wire, digital to analog converter D/A links to each other with processor controls CPU by holding wire, the mode of operation selector switch has general mode, two groups of switch links of decryption mode, processor controls CPU links to each other with decryption mode switch link leg 2 by holding wire, and digital to analog converter D/A links to each other with the decryption mode switch link leg 2 of mode of operation selector switch K by holding wire.The general mode link has leg 1,1 '.Position according to mode of operation selector switch K, this broadcast receiver can work in general mode or decryption mode, when the options button of mode of operation selector switch K places 1-1 ' during the position, this broadcast receiver is operated in general mode, this moment is in full accord with common broadcast receiver, can receive the broadcasting of ordinary amplitude modulation, frequency modulation standard, when the options button of mode of operation selector switch K places 2-2 ' during the position, this broadcast receiver is operated in decryption mode, can receive through ciphered data broadcasting.The mode of operation selector switch can adopt the common double double-pole double throw switch, and processor controls CPU can adopt 89C51 etc., and digital to analog converter can adopt integrated chip AD1855, and IC-card can adopt SLE66C80S etc.
With reference to accompanying drawing, the broadcast receiver operation principle of band IC-card: the effect of antenna is to change aerial radio wave into the signal of telecommunication, this signal is sent to high-frequency receiver, the effect of high-frequency receiver is to select the carrier signal that will receive to amplify, carrier signal after amplifying is given demodulator, and the effect of demodulator is audio detection signal or a digital signal from the carrier signal of carrying information.When working in general mode, mode of operation selector switch K is positioned at 1-1 ' position, the audio signal that demodulator detects is directly delivered to power amplifier, and the effect of power amplifier is that audio-frequency information is amplified, finally deliver to loud speaker through the audio signal of amplifying, be reduced into sound.When working in decryption mode, mode of operation selector switch K is positioned at 2-2 ' position, the digital signal that demodulator detects is delivered to processor controls, and processor controls is responsible for sending digital signal to IC-card and is decrypted, and IC-card carries out authentication, billing operation according to the content of digital signal simultaneously.IC-card returns the digital signal through deciphering to processor controls, processor controls is passed to digital to analog converter D/A to data again, digital to analog converter D/A is converted to simulated audio signal to digital signal, deliver to power amplifier through mode selection switch K again and amplify, the audio signal after amplifying is delivered to loud speaker and is reduced into sound.Power unit provides the complete machine electricity consumption.
Claims (3)
1, a kind of broadcast receiver with IC-card, have antenna, high-frequency receiver, demodulator, power amplifier, power supply, loud speaker, it is characterized in that also having processor controls CPU, IC-card, digital to analog converter D/A, the IC-card dress is inserted in the IC-card socket, link to each other with processor controls CPU by holding wire, digital to analog converter D/A links to each other with processor controls CPU by holding wire.
2, the broadcast receiver of band IC-card according to claim 1 is characterized in that radio devices has mode of operation selector switch K, and the mode of operation selector switch has general mode, decryption mode two group mode switch links.
