Embodiment
Below in conjunction with drawings and Examples the present invention is further described.
As shown in Figure 1, after Intranet checkout equipment 1 detects alert event, the type of analyze reporting to the police, and be translated into the numeral that a string alarm call number adds type of alarm number.For example: checkout equipment 1 is found to catch fire, and the user-defined corresponding type of alarm of catching fire is 01, and the alarm call number of setting is 34567890 in advance, and software will generate this string numeral of 34567890#01 so, and plays corresponding dtmf sound signal.Warning device 2 is analyzed it after receiving the dtmf sound signal, extract 34567890 telephone number of front, dial this phone, play the voice content of 01 type of alarm simultaneously by telephone wire, when 34567890 telephone subscribers answer, will hear and catch fire relevant voice content.The short-message sending alarm principle is similar with telephone call, and just to receive telephone number # back 01-50 be 50 voice messagings to the definition of the receiver module of warning device, dials and play by telephone wire.If the # back is 51-99, then be 49 short message contents, warning device can not dialed by telephone wire, but sends relevant alarming short message to the alarm call that configures by the note modulator-demodular unit by the sim card.
As Fig. 2, shown in Figure 3, Intranet checkout equipment 1 sends the dtmf sound signal to warning device 2, the receiving trap of warning device (as microphone etc.) 3 receives above-mentioned dtmf sound signal, and send dtmf decoder 4 to, after decoding, 4 pairs of above-mentioned signals of dtmf decoder send chip 5 to, chip 5 sends command information according to predefined pattern to voice module 6 or SMS module 7 according to the signal that receives, voice module is dialed the police emergency number and playback by telephone plant 8 after receiving command information, and 7 of SMS module send relevant alarming short message to the alarm call that configures by note modulator-demodular unit 9 by the sim card
Fig. 4 is the paragraph controller of putting of voice module.RBO-7 is an eight-digit binary number segment number data line, and valid data: 0-2550 is quiet, and 1-255 is corresponding sector address, writes the segment number data and promptly begins playback, and this section playback finish to be met 0 and stopped, also can the section of jumping or circulation put certain section, do not use this interface during recording.The pattern and the voice module of SMS module are similar, and the modulator-demodular unit that sends note is by inserting the sim card, and external antenna sends note.Content of short message can be imported in computer by the serial port of modulator-demodular unit.
