Embodiment
Below in conjunction with embodiment, the present invention will be described in detail.
A kind of remote household electrical appliance safety monitoring system based on GSM the present invention relates to, include master controller, on it, be connected with gsm communication module, household electrical appliance or domestic environment (comprising TV, air-conditioning, water heater, electric cooker, lamp, door, curtain etc., is to want controlled object), peripheral sensor, power circuit, reset circuit, crystal oscillating circuit, color screen display module, motor drive module, keyboard input module and photoisolator.Between master controller and gsm communication module, be serial communication, be connected by IO interface with other modules.
Wherein, the model of master controller is STM32; The model of gsm communication module is SIM300; Peripheral sensor sensor includes temperature sensor DS18B20, infrared sensor HS0038, gas sensor ZYMQ-4; The model of color screen display module is TFT-LCD; The model of motor drive module is ULN2003, is used for Driving Stepping Motor; The model of photoisolator is TLP521.
Before system works, first will carry out initialization, this comprises the initialization of master controller and the initialization of gsm communication module.The initialization of master controller comprises the setting of baud rate, interruption etc., and the initialization of the module such as liquid crystal display, each peripheral sensor in color screen display module; The initialization of gsm communication module comprises short message prompt, messaging format, echo setting, inquiry SIM card state etc.Master controller is serial communication with communicating by letter of gsm communication module, and the control information of reading gsm communication module by inquiry serial ports at control module processor realizes the control to module by sending instruction to gsm communication module.In safety monitoring module (each peripheral sensor), the numerical value of each sensor is read in master controller circulation, once when finding that there is fire, gas leak or having the dangerous situations such as thief enters, control gsm communication module SIM300 and put through phone by GSM network to user mobile phone and realize security protection and remote alarming function.
In system, added time clock feature simultaneously, user can be used as alarm clock and uses, facilitate user's setting alarm clock automatically at WA, curtain to be pulled open, or do some fixing things in the set time, as in the time that householder is in, cooking, time is up, the time that system will be set according to alarm clock, electric cooker is opened and cooked.
Be more than hardware design part, below in conjunction with accompanying drawing 5, workflow of the present invention be described in detail:
After master controller electrification reset, first SIM Mobile phone card, liquid crystal display, peripheral sensor are carried out to initialization, after initialization success, read indoor temperature and be shown in liquid crystal display, system enters into normal duty.
At safety monitoring module, whether too high the value of systemic circulation reading temperature sensor, detect indoor temperature; Read the value of gas sensor, detect and whether have gas leak; Read the value of infrared sensor, detect and whether have thief to enter.Occur if any above situation, system according to user-selected be the pattern of leaving home or return home pattern, take different type of alarms.The modular system automatic transfer breath if leave home, or informing user by calling, thus realize security protection and remote alarming function.For strengthening security, in indoor security safeguard function, be provided with two-stage protection, when system detects while having in front of the door people and the residence time to be greater than certain hour, camera will be opened, it is taken pictures, then by Fetion mode, picture is sent on householder's mobile phone, avoid householder to incur loss.
In control module, relate to selection, the design of user security grade and the realization of feedback function of control model.First system will carry out the differentiation of mode of operation, is defaulted as dialing mode.In the time being dialing mode, if user wants to control and monitor indoor, only need dial the Mobile phone card number in gsm communication module, that the number that sets is while making when controller detects, just point out caller ID to input corresponding action command numeral, user can realize long-range to indoor real-time control according to prompting input numeral; In the time that user does not want to use dialing mode, only need in corresponding cell phone software, choose short message mode or Fetion pattern.When present mode is note or Fetion pattern, judge current whether have new message or new Fetion arrival, just judge user's authority if any new message or new Fetion, then determine whether to need to input password according to user right, high authority user does not need password, directly carries out the instruction in note or Fetion; Domestic consumer just carries out the execution of instruction after Password Input is correct, and instruction, in carrying out, has information on display, point out current action object.When after action successful execution, user mobile phone can be received a feedback information, points out the state of current action executing, arrives this, controls function and completes.
It is cited that content of the present invention is not limited to embodiment, and the conversion of any equivalence that those of ordinary skills take technical solution of the present invention by reading instructions of the present invention, is claim of the present invention and contains.
