Description
1, technical field:
The utility model relates to a kind of alarming for help.
2, background technology:
At present, the alarm structure that occurs on the market is comparatively simple, its structure as shown in Figure 1, its principle is as follows: when sensor when extraneous medium changes, export corresponding high level or low level to single-chip microcomputer by comparer, single-chip microcomputer output signal again drives warning device.Its major defect is: can only realize short-distance alarm, incompetent for long-distance alarm, structure is comparatively simple, and function is less.
3, summary of the invention:
The purpose of this utility model provides a kind of alarming for help, and it utilizes present telephone network to realize long-distance alarm, and is multiple functional, realizes intelligent call.
The utility model is achieved by the following technical solution: it comprises single-chip microcomputer and sensor, it also comprises on-off circuit in addition, dialing IC, storer, the signal tone testing circuit, keyboard and display, storer, keyboard and display are connected on the single-chip microcomputer, the output terminal of sensor links to each other with the input end of single-chip microcomputer, on-off circuit is connected local telephone with this machine, the control end of on-off circuit is connected on the single-chip microcomputer, the output terminal of single-chip microcomputer is connected with the input end of dialing IC, the output terminal of dialing IC is connected with local telephone through on-off circuit, the input end of signal tone testing circuit is connected with local telephone through on-off circuit, and the output terminal of signal tone testing circuit is connected with the input end of single-chip microcomputer.
Above-mentioned described speech chip, speech chip is connected on the single-chip microcomputer.
The utility model compared with prior art has following advantage: 1, realize long-distance alarm, utilize present telephone network that alerting signal is transmitted; 2, realize that intelligent call reports to the police, when sensor when extraneous medium changes, single-chip microcomputer dials the telephone number of memory stores immediately, the realization intelligent call; 3, multiple functional, the telephone number of the setting that can oneself want according to the input of user's needs.
4, description of drawings:
Below in conjunction with accompanying drawing the utility model is done detailed explanation:
Fig. 1 is the circuit block diagram of traditional alert device;
Fig. 2 is a circuit block diagram of the present utility model;
Fig. 3 is the circuit diagram of Fig. 2 correspondence.
Embodiment:
As Fig. 2, shown in Figure 3, the utility model comprises single-chip microcomputer (1) and sensor (4), it is characterized in that it also comprises on-off circuit (10), dialing IC (7), storer (8), signal tone testing circuit (6), keyboard (5) and display (3), storer (8), keyboard (5) and display (3) are connected on the single-chip microcomputer (1), the output terminal of sensor (4) links to each other with the input end of single-chip microcomputer (1), on-off circuit (10) is connected local telephone (9) with this machine, the control end of on-off circuit (10) is connected on the single-chip microcomputer (1), the output terminal of single-chip microcomputer (1) is connected with the input end of dialing IC (7), the output terminal of dialing IC (7) is connected with local telephone (9) through on-off circuit (10), the input end of signal tone testing circuit (6) is connected with local telephone (9) through on-off circuit (10), and the output terminal of signal tone testing circuit (6) is connected with the input end of single-chip microcomputer (1).It also comprises speech chip (2) in addition, and speech chip (2) is connected on the single-chip microcomputer (1).
The utility model is to receive on the local exchange by subscriber's line, and in fact it is a terminal device of PTSN net, and during installation, as long as be connected in parallel on the telephone set, it has intelligent dialling function, and concrete function is as follows:
1) it can send double-audio signal, can store maximum 5 telephone numbers, and these numbers can be
Be user's oneself the relatives or the PAS mobile phone of unit, and provide relevant by local exchange
Information, number also can be revised, because these numbers by the needs input of user according to oneself
Sign indicating number all is urgent purposes, therefore, must show simultaneously during input, in case wrong input.
2) it has intelligent function, and when the user button number of sending out, button must continue ability more than 1 second
As effective action, it can differentiate subscriber's telephone line automatically is busy or spare time, if the user
The words line is just busy, is temporarily stopping dialling 2 seconds, and dialing automatically then is up to the subscriber's telephone line free time
In addition, it can judge whether the other side's circuit is busy, if busy tone, it returns and transfers to next automatically
The telephone number of individual storage, and judge further whether the other side has received the signal that sends,
Only judging that the other side has received that just being counted as merit under the situation of signal sends signal, so grasps
Work is till the telephone number of all storages is all transferred to.
3) this alarm is supporting with the corresponding calculated machine platform, and the management that can carry out subscriber data is also passable
Follow the tracks of the location.
