Abstract

The utility model discloses an antitheft alarm system. The antitheft alarm system is characterized in that the antitheft alarm system comprises an infrared induction module used for detecting human body signals, a reception and conversion module used for receiving the human body signals and converting the human body signals into digital signals, a control circuit communication module used for receiving the digital signals and sending alarm instructions, and a relay module used for controlling opening and locking of an antitheft lock. The input terminal of the reception and conversion module is connected with the infrared induction module, the output terminal of the reception and conversion module is connected with the input terminal of the control circuit communication module, and the output terminal of the control circuit communication module is connected with the input terminal of the relay module. By employing an electromagnetic lock, the break-in people are prevented from entering a bedroom; by employing an infrared sensor to detect infrared signals emitted by human bodies, false alarms are avoided; by employing a one-chip microcomputer as a master control module, the control circuit is simple in structure and high in reliability; users can control the opening and locking of the electromagnetic lock through a wireless remote controller; and by employing a GSM communication module, the users can receive alarm information.

Description

A kind of guard against theft and alarm system

Technical field

The utility model relates to a kind of guard against theft and alarm system.

Background technology

Because a lot of residential quarters are more old, Comparison of Management falls behind, and the stolen phenomenon of family happens occasionally.The very small and exquisite exquisiteness that a lot of Minitype infrared devices do although had in prior art and highly sensitive, average family are used also universal, or very expensive complexity, or reliability is very low.At present, the popularity rate of Household infrared warning system is not high.Burglar alarm major part on market only has auditory tone cues, can't remote alarms.Although vibration alarm is also arranged, because in residential quarter, often someone walks about, rate of false alarm is high.These all fundamentally can't the efficient solution threat of method intruder to owner's life and property by no means.Therefore, need a kind of simple, inexpensive, effective, guard against theft and alarm system of being easy to promote.

The utility model content

The utility model purpose is for the deficiencies in the prior art, provides a kind of and can find effectively, in time illegal chamber entrant GSM Infrared intrusion detector that can Realtime Alerts.

The utility model for achieving the above object, adopts following technical scheme:

A kind of guard against theft and alarm system is characterized in that: described guard against theft and alarm system comprises: for detection of the infrared induction module of human body signal; For receiving the reception modular converter that human body signal is converted to digital signal; Control circuit communication module for the concurrent alert instruction of delivering newspaper of receiving digital signals; For controlling the relay module of theftproof lock switch; The input end of wherein said reception modular converter connects described infrared induction module, and the output terminal of described reception modular converter connects control circuit communication module input end, and described control circuit communication module output terminal connects the input end of relay module.

It is further characterized in that: described guard against theft and alarm system also comprises the hummer for alarm calls, and the input end of described hummer connects the output terminal of described control circuit communication module.

It is further characterized in that: described relay module comprises relay and electromagnetic lock, and the output terminal of described relay connects electromagnetic lock.

It is further characterized in that: described infrared induction module comprises: Radio infrared sensor and be used to controlling the Digiplex of hummer and electromagnetic lock switch, the output terminal of described Radio infrared sensor and Digiplex is connected respectively described reception modular converter.

It is further characterized in that: described reception modular converter comprises: wireless receiving module and A/D converter, the output terminal of described wireless receiving module connects A/D converter.

It is further characterized in that: described control circuit communication module comprises for receiving digital signals and sends the single chip machine controlling circuit of instruction, and described single chip machine controlling circuit inside is provided with the GSM communication module for wireless telecommunications.

It is further characterized in that: described guard against theft and alarm system also comprises power supply and the switch for power supply, and the input end of described switch connects power supply, and the output terminal of described switch connects single chip machine controlling circuit.

Compared with prior art, guard against theft and alarm system of the present utility model, prevent that by electromagnetic lock cracker from entering bedroom, the efficient solution threat of method intruder to owner's lives and properties by no means; The infrared signal that adopts the infrared sensor human body to send, can not produce wrong report; Adopt single-chip microcomputer as main control module, make control circuit simple in structure, reliability is high; The user can use Digiplex to carry out switch control to electromagnetic lock; Adopt the GSM communication module, as long as the place of mobile phone signal is arranged, user's information that just can receive the report for police service.

The accompanying drawing explanation

Fig. 1 is the utility model structural representation;

Wherein: 1, power supply; 2, switch; 3, Radio infrared sensor; 4, wireless receiving module; 5, A/D converter; 6, Digiplex; 7, single chip machine controlling circuit; 8, hummer; 9, relay; 10, electromagnetic lock.

Embodiment

A kind of guard against theft and alarm system as shown in Figure 1, be comprised of power supply 1, switch 2, Radio infrared sensor 3, wireless receiving module 4, A/D converter 5, Digiplex 6, single chip machine controlling circuit 7, hummer 8, relay 9, electromagnetic lock 10.

Described guard against theft and alarm system is achieved as follows:

The user presses switch 2, and power supply 1 is to single chip machine controlling circuit 7 power supplies, and after single chip machine controlling circuit 7 initialization, warning system enters holding state.

The Radio infrared sensor 3 of theftproof lock is placed on to the entry door position, after detecting someone and swarm into, Radio infrared sensor 3 sends signal to wireless receiving module 4, wireless receiving module 4 sends to single chip machine controlling circuit 7 after by A/D converter 5, simulating signal being transformed into to the manageable digital signal of single-chip microcomputer, after single chip machine controlling circuit 7 received signal: (1) sent instruction to hummer 8, and hummer 8 starts to pipe; (2) to relay 9 transmitted signals, the normally opened contact closure of relay 9, electromagnetic lock 10 energisings automatically lock, and prevent that cracker from threatening user's safety.GSM communication module 7 sends alarming short message according to program to default mobile phone and infrastructure management company, plays alarm function.

The user can also use Digiplex 6 to close hummer 8 or switch electromagnetic lock 10.

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
