Description

Wireless sensing network intelligent household warning system based on CC2530

Technical field

Wireless sensing network intelligent household warning system based on CC2530 belongs to the Smart Home field.

Background technology

At present, modern architecture all can be installed the automatic alarm system of difference in functionality selectively.Because automatic alarm system is the nervous system of buildings, it can be experienced, receive the early signal of unsafe condition and reach alarm, gives the alarm and informs user and peripheral resident simultaneously.It can be given and live, people busy or that have a rest at home provide the great sense of security.

The utility model content

The design adopts the core of CC2530 as node, forms a small-sized wireless sensor network, and as shown in Figure 1, in figure, each node is identical node to its principle of compositionality schematic diagram.

Wireless sensing network intelligent household warning system based on CC2530 is characterized in that: be included in the sensor that connects on the CC2530 chip and signals collecting thereof and amplifying circuit, warning circuit, RF radio transmitter; The CC2530 chip communicates by wireless mode and central host, and central host and user mobile phone interrelate;

Described sensor is combustible gas sensor, smoke transducer, infrared sensor of the human body thrin or combination in any.

Further: also be included in two conducting probes that connect on the CC2530 chip.

The utility model is monitored for gas leak, domestic water leakage, fire and four kinds of dangerous situations of burglary of often occurring in Modern Family, and the utility model is monitored mainly for the following four kinds of unsafe conditions that easily occur in modern house:

1) gas leak: coal gas is the fuel that Modern Family is generally used, and the utility model adopts the MQ-5 combustible gas sensor to be monitored coal gas;

2) fire: the utility model adopts the MQ-2 smoke transducer to be monitored the fire situation;

3) domestic water leaks: the utility model adopts conducting probe to be monitored water leakage situation;

4) burglary case: the utility model adopts infrared sensor of the human body SD02 to be monitored swarming into indoor stranger.

Embodiment

Wireless sensor network is by being deployed in cheap microsensor nodes a large amount of in monitored area, the multihop self-organizing network formed by communication, cover the information of perceived object in geographic area with perception collaboratively, collection, processing and transmission network, and finally these information are sent to the network ownership.Wireless sensor network in the design is a small-sized simple sensor network, and each node and aggregation node communicate, and send the sensor information collected to aggregation node.

Connection diagram between the node modules as shown in Figure 2.

Select the control device of CC2530 as Smart Home warning system node in the design, access respectively MQ-5 combustible gas sensor, MQ-2 smoke transducer, infrared sensor of the human body SD02, two conducting probes and a loudspeaker be connected on Music Clip on CC2530.Circuit structure diagram is as shown below:

In Fig. 3, crystal oscillator XTAL1 is the 32-MHz oscillator, and XTAL2 is the 32.768-kHz crystal oscillator.

The utility model adopts CC2530 as aggregation node, and its circuit diagram as shown in Figure 4.In Fig. 4, crystal oscillator XTAL1 is the 32-MHz oscillator, and XTAL2 is the 32.768-kHz crystal oscillator.

As shown in Figure 3, CC2530, as the core control part of node, connects respectively combustible gas sensor MQ-5, smoke transducer MQ-2, infrared sensor of the human body SD02, two conducting probes and a loudspeaker that connects Music Clip.Whether MQ-5 has gas leak for monitoring, the MQ-2 smoke transducer is for monitoring whether breaking out of fire, it is indoor whether infrared sensor of the human body has the stranger to enter for monitoring, two conducting probes are for monitoring on ground whether water is arranged, when mainly being away from home for owner, this may forget that the situation of turning off the tap designs (while on ground, ponding being arranged, two probes can be communicated with conduction).When sensor detects while causing danger situation, the current signal that sensor sends is transformed into voltage signal by middle amplifier, then the ADC of CC2530 is sampled and is judged this voltage signal, then drive the loudspeaker be connected on Music Clip to be reported to the police, while RF circuit wireless signal emission, alert data is issued to aggregation node, aggregation node sends to wireless signal the center Receiving Host again, the center Receiving Host can interrelate with user's mobile phone, Receiving Host will send alarm signal to user mobile phone, make the user can learn that unsafe condition has occurred the family of oneself, thereby make a response rapidly.

When owner stays out, all sensors all can be opened with monitoring indoor environment information, when owner is in, need to close infrared sensor of the human body, the K switch of infrared sensor of the human body marks on Fig. 3, and, when owner is in, if dangerous situation occurs, loudspeaker also can be reminded owner so.

All place a sensor node in each room, these nodes communicate by Zigbee protocol and aggregation node, and aggregation node communicates by wireless mode and central host, and central host and user mobile phone interrelate.The connection diagram of node modules is as shown in part in dotted line frame in Fig. 2.

CC2530 is contacting sensor and warning circuit equipment.In the design, select the CC2530 chip as the joint core device.

When sensor detects in environment dangerous information, the current signal that sensor sends is transformed into voltage signal by middle amplifier, then the ADC of CC2530 is sampled and is judged this voltage signal, then drive the loudspeaker be connected on Music Clip to be reported to the police, while RF circuit wireless signal emission, alert data is issued to the center Receiving Host, the center Receiving Host can interrelate with user's mobile phone, Receiving Host will send alarm signal to user mobile phone, something unexpected happened to make the user can learn oneself family, thereby make a response in the very first time, take emergency measures.

Workflow

The principle of work of Smart Home warning system is the information collected to be converted into to the analog electrical signal of amplification by collecting sensor signal and amplifying circuit, and analog to digital conversion circuit is sent into CC2530 after again this analog signal conversion being become to the discernible digital signal of CC2530 chip.CC2530 is processed this digital signal, and to the data analysis after processing.When sensor detects dangerous environmental information, the sensor signal of input CC2530 is non-vanishing, warning circuit and RF radio transmitter will be activated, being connected to loudspeaker on Music Clip in warning circuit will ring, the center Receiving Host receives alert data information simultaneously, then send warning message to user mobile phone, notify the user.In this system, the program flow diagram of sensor node as shown in Figure 5.
