Background technique

With the replacement of mobile phones, a large number of old button-type mobile phones have become electronic waste. Whether the old mobile phones can be transformed into other practical products that can be used, the answer is yes, but how to turn these wastes into treasures for reuse, There has been no good solution. The current common practice is to refurbish the old mobile phone or remove the communication module, and use the communication module to other control systems.

Wireless alarm devices have become common alarms in daily life and industrial production, and are used in home fire prevention and anti-theft, automobile fire prevention and anti-theft, warehouse fire prevention and anti-theft, etc. Most of the existing wireless alarms are made of integrated controllers, which are costly and need to consume telephone charges; there are also alarms made of long-distance wireless transmission modules, which are easy to be damaged and interfered, and the monitoring distance Subject to certain restrictions.

Contents of the invention

The technical scheme of the utility model is: a remote fire prevention and anti-theft alarm, including a thermal infrared human body sensor, a smoke sensor, a controller, a dialer, an alarm sending end, a user mobile receiving terminal, a power supply, and a controller connected to a thermal infrared human body Inductor, smoke sensor, dialer, power supply, the dialer is connected to the alarm sending end, and the alarm sending end is wirelessly connected to the mobile receiving terminal of the user through the mobile base station. The alarm sending end is the user's waste button mobile phone, the user mobile receiving terminal is the mobile phone that the user carries on the body, and the controller can control the dialer to send the alarm according to the signals sent by the thermal infrared human body sensor and the smoke sensor. Dial the number of the user's mobile receiving terminal on the terminal.

When a theft suspect enters the sensing range of the alarm or the smoke concentration exceeds the normal range, the thermal infrared human body sensor and smoke sensor will send a human body or smoke signal to the controller. After the controller detects the human body or smoke signal, it will control the dial The device dials the number of the user's mobile receiving terminal that has been set at the alarm sending end. After receiving the call from the alarm sending end, indicating that there is an abnormal situation, the user can immediately take corresponding measures to ensure the safety of the monitored items.

The utility model has the following beneficial effects: waste reuse, resource saving, low production cost, convenient installation and use, high safety, strong anti-interference, fire prevention and anti-theft monitoring is not limited by distance, alarm does not generate costs, and is used in households and warehouses , Automobiles, anti-theft doors, doors and windows, safes, valuables fire prevention and anti-theft monitoring.

detailed description

Embodiments of the utility model will be further described below in conjunction with the accompanying drawings.

A remote fire and burglar alarm, comprising a thermal infrared human body sensor 1, a smoke sensor 2, a controller 3, a dialer 4, an alarm sending terminal 5, a user mobile receiving terminal 6, a power supply 7, and a controller 3 connected to a thermal infrared human body Inductor 1, smoke sensor 2, dialer 4, power supply 7, dialer 4 is connected to alarm sending end 5, and alarm sending end 5 is wirelessly connected to user's mobile receiving terminal 6 through mobile base station, it is characterized in that: described dialer 4 is Utilize the device of semi-conductor triode control mobile phone button, described alarm sending end 5 is the waste button mobile phone of user, and described user mobile receiving terminal 6 is the mobile phone that user carries on the body, and described controller 3 can be according to thermal infrared human body sensor 1 With the signal sent by the smoke sensor 2, the control dialer 4 dials the number of the user's mobile receiving terminal 6 on the alarm sending end 5.

Thermal infrared human body sensor 1 is composed of three-legged human body infrared sensor module HC-SR501 human body infrared sensor module; HC-SR501 human body infrared sensor module is an automatic control module based on infrared technology, using LHI778 infrared probe design, high sensitivity and reliability Strong, ultra-low voltage working mode, can sense whether there is a human body within a range of 7 meters, and send a low level to the controller 3 when there is no one in the sensing range, once a human body appears within the sensing range, Immediately send a high level to the controller 3, and the low level is not restored until the human body leaves the sensing range.

The smoke sensor 2 adopts the NIS-09 ion smoke sensor; the smoke sensor NIS-09 is a device that senses the smoke concentration in the air and converts it into a voltage signal and outputs it to the controller 3. When the smoke concentration in the air is low, the smoke The sensor stably outputs a voltage of about 5.6V. Once a fire occurs and smoke enters the smoke sensor, the output voltage will decrease, and the fire information will be transmitted to the controller 3 .

The dialer 4 is composed of multiple PNP semiconductor transistors, and each button needs a PNP semiconductor transistor; the PNP semiconductor transistor can use the weak current output by the controller 3 to control the large current in the button of the alarm sending terminal 5 to simulate the pressing of the button , the collector and the emitter of the PNP semiconductor transistor are respectively connected to the two contacts of the button, and the base is connected to the output port of the controller 3.

Controller 3 is made up of single-chip microcomputer, power supply circuit, audio socket and peripheral device; Described single-chip microcomputer selects 8 or 12 or 16 bits for use, and power supply circuit adopts DC-DC power supply IC and peripheral device design, selects ATmega16 for use as single-chip microcomputer, power supply circuit adopts ME2100A33P and peripheral device design 5V power supply scheme; controller 3 receives signals from thermal infrared human body sensor 1 and smoke sensor 2 through its own I/O input and output ports, and sends key information to dialer 4 to control alarm sender 5 to dial.
