Embodiment

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

As shown in Figures 1 and 2, card insert type long distance wireless warning device is made of casing 2 and inner control circuit thereof, wherein the front panel of casing is provided with 12 buttons 4, is provided with a telescopic receiving antenna 1 and the IC-card slot 3 that can insert IC-card above the casing; The side of casing is provided with a battery cover 6, and there is a battery compartment 5 battery cover inside; Be provided with the power interface of a telephone line interface that can insert telephone wire 7, a telephony interface that is connected with telephone set 8 and an external direct current power supply below the casing.This device is provided with outer for direct supply and two kinds of power supply modes of battery, even support outward when running into abnormal factorses such as powers failure and can not power for direct supply, still can use battery to work on, and guarantees the work of this device continous-stable.

As shown in Figure 3, control circuit in the casing is by microprocessor, the wireless receiving processor, decoding processor, the keyboard processing module, the DTMF transceiver, speech processor and IC-card processor constitute, wherein, wireless alarm signal is input to the input end of wireless receiving processor through receiving antenna, the output terminal of wireless receiving processor is connected to the input end of decoding processor, the output terminal of decoding processor is connected to the interrupt interface of microprocessor, the I/O interface of microprocessor respectively with the keyboard processing module, the DTMF transceiver, speech processor, the IC-card processor is connected, the keyboard processing module is made of the 74HC164 chip series connection of two TI companies, its input end is connected with button on the casing, and the DTMF transceiver is connected with telephone line interface on the casing.
