Specific implementation method
The present invention puts forward state monitoring method in a kind of pot of carrying button based on Intelligent cooker lid. This Intelligent cooker lid is carriedButton structurally has a hollow cavity, and central control module, pot cover state-detection are installed in hollow cavityQuantity of state acquisition module, wireless communication module and battery in module, pot.
As shown in Figure 1, Intelligent cooker lid is carried button can be in following several states: sleep state, holding state,Wherein, under holding state, can, according to the condition of setting, enter at any time detected state and transmission state. ?When sleep state, the power consumption of central control module is extremely low, and only reservation response pot cover state monitoring module providesThe hardware interrupts function that level signal triggers, closes other power dissipating unit.
Under holding state, central control module power consumption is still lower, but increased overtime to hardware timer afterThe function that interrupt signal responds. The level that central control module response pot cover state monitoring module is sentAfter signal, sleep state terminal, Intelligent cooker lid is carried button and is entered holding state from sleep state.
Entering under the duty that comprises detected state and the state of transmission, central control module power consumption is higher,Can work in coordination with pot interior quantity of state acquisition module and wireless communication module completes the collection to quantity of state in pot and will adoptIn the pot of collection, quantity of state sends to the function of miscellaneous equipment.
Pot cover state detection module inside comprises a pot cover state detection sensor, for monitor pot cover whether fromDuty is not transformed into duty. This sensor can be a piezoelectric sensing that can detect vibratory outputDevice, can detect that pot cover picked up the action of rear placement. Also can be a capacitance type touch key, peaceBe contained in pot cover and carry button surface, can detect that pot cover proposes the touched action of button. Also can be the two gold of a useBelong to sheet and make the temperature switch of temperature-sensing element, can detect that kettle temperature is elevated to duty.
In above-mentioned three kinds of pot cover status monitoring sensors, vibration piezoelectric sensor and temperature switch are passive devicePart, does not need power supply supply when work; Capacitance type touch key is active device, only needs very little when workPower consumption. The state variation that vibration piezoelectric sensor and capacitance type touch key sense is by a letterNumber amplifying circuit, can trigger a level signal; Temperature switch can directly be used for triggering a level letterNumber. This level signal, as the hardware interrupt access central controller of central control module, is controlled central authoritiesDevice processed wakes up from sleep state, enters holding state.
Central control module enters after holding state, enters work shape by triggering quantity of state acquisition module in potState, starts quantity of state in pot to detect. If quantity of state continues in stable state in the pot detectingAfter a period of time, and the stationary value of this quantity of state meets pot cover in the feature of duty not, central authoritiesControl module thinks that cooking process finishes, and automatically reenters sleep state by holding state, to reduce intelligencePot cover is put forward the power consumption of button.
In pot, quantity of state acquisition module comprises a state acquisition sensor, and this sensor is put forward button hollow by pot coverStructure is fixed to pot cover inside, for detection of quantity of state in pot. Quantity of state pick-up transducers can be one orPerson is multiple. State acquisition sensor can adopt touch sensor or non-contact sensor. For example, to temperatureThe collection of tolerance adopts temperature sensitive resister or infrared type temperature sensor; Adopt piezoelectricity to pass to the collection of amount of pressureSensor; The collection of humidity amount is adopted to Ceramic Humidity Sensor; It is right to be converted to the measurement of water level heightThe measurement of water surface distance, infrared distance sensor can be used for gathering water level height; Collection to amount of color canTo adopt integrated light-frequency sensor, TCS230 is one of them representative; Collection to taste canAdopt the Electronic Nose sensor of extensive use to realize.
Central control module adopts a hardware timer to trigger the work of quantity of state acquisition module in pot. This timingThe time-out time of device, can be according to the absolute value of quantity of state in the pot detecting with respect to last monitoring variableChanging value change. The changing value of timer expiry time is in a serial number interval. This numerical value intervalMaximum according to meet trap state accuracy of measurement require minimum setting; The minimum of a value in this numerical value interval is pressedAccording to the maximum setting that meets trap state quantitative change required precision. State in the setting value of fixed time interval and potAbsolute value or the variable quantity of amount can become certain linear relationship, also can become certain exponential relationship or itsIts any form that can represent with published mathematic(al) representation.
Intelligent cooker lid is carried the interior quantity of state of pot that button obtains by quantity of state acquisition module in pot, both can be by instructionLamp or display screen show in this locality, also can pass in the mode of wireless telecommunications by wireless communication moduleMiscellaneous equipment.
Intelligent cooker lid is carried the communication of button and miscellaneous equipment, can be according to agreement to send nonreply, to send outSend-confirm or ask-reply one or more in three kinds of modes. Wherein send nonreply and transmission-confirmation mode is active transfer, and request-response mode is passive transmission.
Adopt passive transfer mode, send control mode comparatively simple, central control module only need to receive pleaseWhile asking pot interior quantity of state message, enter transmission state, trigger wireless communication module and enter duty by requestIn pot, quantity of state sends; After transmission finishes, central controller returns to holding state by transmission state automatically.
If adopt the initiatively communication mechanism of send mode, only have miscellaneous equipment first to carry button to Intelligent cooker lid and send outSend after status request message, Intelligent cooker lid is carried button and just can be started to send quantity of state in the pot detecting to this equipment;And stop after message at the status request that receives miscellaneous equipment transmission, stop detecting to this equipment transmissionQuantity of state in pot. Especially, if adopt the communication mechanism that sends-confirm, carry button at Intelligent cooker lid and send out continuouslySend after the interior quantity of state of several times pot, all do not receive the confirmation message of relevant device, stop passing through channel radioLetter module sends quantity of state in pot to this equipment; Until again receive the status request message that this equipment sends.
While adopting the communication mechanism of active send mode, central controller is established by the time-out time of hardware timerPut, clocked flip enters transmission state; Or the inspection that the quantity of state also can current detection arriving is relatively lastThe changing value of measuring exceedes after a certain threshold value, also can trigger the transmission state that enters. Enter after transmission state,Central controller triggers wireless communication module and enters duty by quantity of state transmission in the pot of request; Send knotShu Hou, central controller returns to holding state by transmission state automatically.
Wireless communication module sends the message that quantity of state detected to miscellaneous equipment, can be broadcasting packet, multicastAny in message or unicast message. Wherein send-confirmation or request-responding communication mode are manyAdopt unicast message, send without confirming that communication mode can adopt broadcasting packet, multicast message or listReport any in literary composition.
Intelligent cooker lid carry button can detect kettle temperature, pressure, humidity, height of water level, color or smell thisSome or all of in a little quantity of states. Different quantity of states can adopt identical state-detection and send planSlightly, also can adopt different state-detection and sending strategy. Accordingly, as long as wherein a kind of quantity of state is fullFoot state-detection or send when condition, Intelligent cooker lid is carried button just from holding state to detected state or transmissionState conversion; But all quantity of state does not meet state-detection or sends when condition, just can be byDetected state or the state of transmission auto-returned holding state.
In order to show that Intelligent cooker lid puies forward the duty of button, can also carry a LED is installed on button at Intelligent cooker lidIndicator lamp. Intelligent cooker lid is carried button in the time of sleep state, and LED lamp goes out; When in holding state, LEDLamp is bright; When in detected state, LED lamp glimmers with lower frequency; When in the time sending state, LEDLamp glimmers with upper frequency.
