Described temperature sensing device is Pt100 Pt Resistance Temperature Measuring Circuit, so that temperature data is converted to voltage data.
Described knob position correspondence connects slide rheostat, obtains described knob position information with the resistance change for use by slide rheostat.Further, described slide rheostat connects a precision resistance in dividing potential drop mode, is converted into magnitude of voltage by knob position and sets this voltage threshold with the threshold value according to flame.
The temperature detection of described gas-cooker and warning device 10 also include for the setting of temperature pre-warning value, the setting of overheating warning duration, knob opening early warning duration sets, alarm times transfinites number of times setting, for the setting of closed electromagnetic valve state lower knob number of starts early warning value, for the alert data setting module of the sight early warning setting of opens solenoid valve under knob unlatching sight, described alert data setting module is connected with described judge module 13, makes contrast judgement according to setting numerical value with current corresponding numerical value for judge module 13.
In the present embodiment, described wireless communication module 16 is WIFI module, and described electromagnetic valve is normally opened self-locking type electromagnetic valve, and temperature detection and the warning device 10 of described gas-cooker are connected with mains-supplied circuit, and described display device 15 is touch control screen.
The temperature detection of gas-cooker and the concrete application specific details of warning device that there is provided this utility model below are described in detail.
Temperature detection principle: directly detecting the temperature near burner by the way of PB100 platinum resistor temperature measuring, the most directly, reliability is high.
Temperature detection means: utilize constant-current source circuit that PB100 platinum resistance carries out resistance-voltage conversion, temperature data is converted into voltage, is transmitted to remote server by WIFI after gathering this voltage data with intelligent chip.In order to improve accuracy in detection, by the way of being averaging by multi collect and after rejecting extreme value, prevent the judgement to gathering data of the impulse disturbances of interval.To use two-way temperature sensor (respectively two kitchen ranges on corresponding flame sensitive spot or corresponding kitchen range) that temperature at two is acquired, and as long as there being temperature to exceed the duration that the temperature of setting sets, then can produce temperature alarming information.
Knob Cleaning Principle: utilize the mode of knob position correspondence slide rheostat resistance, by obtaining the positional information of knob to the collection of resistance.
Means implemented by knob: on circuit realiration, then use the mode of this resistance Yu precision resistance dividing potential drop, knob position is converted into magnitude of voltage, set this voltage threshold according to the threshold value of flame, i.e. exceed this threshold value and then can be considered there is flame.In order to improve the accuracy of detection, the mode of employing action algorithm identifying whether to open knob, so-called action algorithm is intended to utilize spinning movement identification during sparking, coordinates the detection of start position；Equally, also can identify this action when closing fire, be recorded as the end of the most complete switch.
Electromagnetic valve Cleaning Principle: open and close gas supply by controlling the switch of electromagnetic valve.Electromagnetic valve can select normally opened self-locking type, works in open state under usual state, when being in self-locking state after needs control action, it is not necessary to be persistently energized, and saves energy.
Means implemented by electromagnetic valve: for the sake of security, can judge electromagnetic valve state when knob action every time, if be closed, recognize knob and reach certain number of times valve then can be pointed out to be not switched on；On the contrary, if in the case of knob is not turned off, receive instruction unpack burnt gas valve, then can return gas leakage warning.Under normal circumstances, if be detected that temperature is too high, and exceeding the threshold value of setting, then can trigger warning, if reported to the police without response, then can close electromagnetic valve.
Specific works flow process: detection warning device can be dynamically connected the wifi network of family certainly, and after having connected, this equipment can detect the position of the temperature on gas kitchen ranges and knob, judges whether, with this, the state that is effectively open.If effectively opening, then with remote server communication statement.In emergency circumstances, it is also possible to cut off gas supply by controlling the electromagnetic valve on gas pipeline.Specifically, first gather during original state and detect temperature data, it is judged that state also decides whether to report to the police, and reporting to the police has two kinds, and one is that temperature over-range is reported to the police, and one is to reveal to report to the police herein.Detecting knob position data the most again, identification maneuver algorithm updates knob position information, for revealing judgement service next time.Finally detection electromagnetic valve state, this state only when repeatedly reporting to the police invalid, and just can turn off electromagnetic valve when of mandate, it is ensured that last barrier of safety.Wherein, temperature sensing device uses two temperature detection probe, the highest high temperature being resistant to 300 degree, and temperature detection is reliable and stable, and knob position detection coordinates temperature detection, is greatly improved Detection accuracy, can detect temperature over-range and gas leakage two states, and report to the police.Can design temperature detection the time limit, the leak detection time limit, and alarm times set and actuation of an alarm privilege etc. parameter, meet different requirement objectives.Equipment uses mains-supplied, and build is small and exquisite, it is simple to install, and uses domestic wif i as transport vehicle, realizes remotely monitoring with cloud server communication.This equipment has the multiple sense channel of temperature, button and electromagnetic valve, can identify temperature and leakage information, it may also be necessary to cut off gas supply.
nullThe temperature detection of gas-cooker provided by the utility model and warning device，With knob、Electromagnetic valve and temperature sensing device connect respectively，Acquisition module receive temperature sensing device sensing temperature and sense temperature time long data、Electromagnetic valve switch data、Long data when knob position data and knob opening，Processing module controls judge module after receiving data and be made whether to meet the judgement of alert if，Specifically，The temperature data judging unit that transfinites judges whether temperature value transfinites，When judging that temperature value transfinites，Temperature over-range duration judging unit judges whether the duration of this temperature transfinites，If duration also transfinites，Processing module drives warning device to send alarm，The effective judging unit of knob position judges that knob position is the most effective，When knob position is effective，Then knob opening duration judging unit judges whether knob opening duration transfinites，If duration also transfinites，Processing module drives warning device to send alarm，Alarm times transfinite judging unit repeatedly send for warning device alarm without response time，Described closed electromagnetic valve is driven by processing module.This device can also carry out communication by wireless communication module module and exterior terminal, it is achieved that automatization's early warning and emergency processing and long-distance intelligent operation.
