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 carried button structurally a hollow cavity, and quantity of state acquisition module, wireless communication module and battery in central control module, pot cover state detection module, pot are installed in hollow cavity.
As shown in Figure 1, Intelligent cooker lid carry button can be in following several states: sleep state, holding state, wherein, under holding state, can, according to the condition of setting, enter detected state and transmission state at any time.In the time of sleep state, the power consumption of central control module is extremely low, and the hardware interrupts function that the level signal that only reservation response pot cover state monitoring module provides triggers, closes other power dissipating unit.
Under holding state, central control module power consumption is still lower, but has increased the function that the overtime rear look-at-me of hardware timer is responded.After the level signal that central control module response pot cover state monitoring module is sent, 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 the function that pot interior quantity of state acquisition module and wireless communication module complete the collection to quantity of state in pot and quantity of state in the pot gathering sent to miscellaneous equipment.
Pot cover state detection module inside comprises a pot cover state detection sensor, for monitor pot cover whether never duty be transformed into duty.This sensor can be a piezoelectric sensor that can detect vibratory output, can detect that pot cover picked up the action of rear placement.Also can be a capacitance type touch key, be arranged on pot cover and carry button surface, can detect that pot cover proposes the touched action of button.Also can be a temperature switch of making temperature-sensing element with bimetallic strip, 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 device, do not need power supply supply when work; Capacitance type touch key is active device, only needs very little power consumption when work.The state variation that vibration piezoelectric sensor and capacitance type touch key sense, by a signal amplification circuit, can trigger a level signal; Temperature switch can directly be used for triggering a level signal.This level signal, as the hardware interrupt access central controller of central control module, is waken central controller up from sleep state, enters holding state.
Central control module enters after holding state, enters duty by triggering quantity of state acquisition module in pot, starts quantity of state in pot to detect.If quantity of state continued after steady state (SS) a period of time in the pot detecting, and the stationary value of this quantity of state meets pot cover in the feature of duty not, central control module thinks that cooking process finishes, automatically reenter sleep state by holding state, put forward the power consumption of button to reduce Intelligent cooker lid.
In pot, quantity of state acquisition module comprises a state acquisition sensor, and this sensor is carried button hollow structure by pot cover and is fixed to pot cover inside, for detection of quantity of state in pot.Quantity of state pick-up transducers can be one or more.State acquisition sensor can adopt touch sensor or non-contact sensor.For example the collection of Temperature Quantity is adopted to temperature sensitive resister or infrared type temperature sensor; The collection of amount of pressure is adopted to piezoelectric sensor; The collection of humidity amount is adopted to Ceramic Humidity Sensor; Measurement to water level height can be converted to the measurement to water surface distance, and infrared distance sensor can be used for gathering water level height; Can adopt integrated light-frequency sensor to the collection of amount of color, TCS230 is one of them representative; Can adopt the Electronic Nose sensor of widespread use to realize to the collection of taste.
Central control module adopts a hardware timer to trigger the work of quantity of state acquisition module in pot.The time-out time of this timer, can and change with respect to the changing value of last monitoring variable according to the absolute value of quantity of state in the pot detecting.The changing value of timer expiry time is in a serial number interval.The maximal value in this numerical value interval is according to the minimal value setting that meets the requirement of trap state accuracy of measurement; The minimum value in this numerical value interval is according to the maximum value setting that meets trap state quantitative change accuracy requirement.The setting value of fixed time interval can become certain linear relationship with absolute value or the variable quantity of quantity of state in pot, also can become certain exponential relationship, or other 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 show in this locality by pilot lamp or display screen, also can pass to miscellaneous equipment in the mode of wireless telecommunications by wireless communication module.
Intelligent cooker lid is carried the communication of button and miscellaneous equipment, can be according to agreement to send nonreply, transmission-confirm or to ask-reply one or more in three kinds of modes.Wherein send nonreply and transmission-confirmation mode is active transfer, request-response mode is passive transmission.
Adopt passive transfer mode, send control mode comparatively simple, central control module only need to enter transmission state in the time receiving in request pot quantity of state message, triggers wireless communication module and enters duty by quantity of state transmission in the pot of request; 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 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 sending quantity of state in the pot detecting to this equipment.Especially, if adopt the communication mechanism that sends-confirm, carry button at Intelligent cooker lid and send continuously in several times pot after quantity of state, all do not receive the acknowledge message of relevant device, stop sending quantity of state in pot by wireless communication module 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 by the time-out time setting of hardware timer, and clocked flip enters transmission state; Or also can current detection to quantity of state relatively the changing value of last detection limit exceed 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; After transmission finishes, central controller returns to holding state by transmission state automatically.
Wireless communication module sends and the message of quantity of state detected to miscellaneous equipment, can be any in broadcasting packet, multicast message or unicast message.Wherein send-confirm or request-responding communication mode adopts unicast message more, send without confirmation communication mode and can adopt any in broadcasting packet, multicast message or unicast message.
Intelligent cooker lid is carried button can detect some or all of in these quantity of states of kettle temperature, pressure, humidity, height of water level, color or smell.Different quantity of states can adopt identical state-detection and sending strategy, also can adopt different state-detection and sending strategy.Accordingly, as long as wherein a kind of quantity of state meets state-detection or sends when condition, Intelligent cooker lid carry button just from holding state to detected state or transmission state change; But when all quantity of state does not meet state-detection or the condition of transmission, just can be by detected 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 light is installed on button at Intelligent cooker lid.Intelligent cooker lid is carried button in the time of sleep state, and LED lamp goes out; When in holding state, LED lamp is bright; When in detected state, LED lamp glimmers with lower frequency; When in the time sending state, LED lamp glimmers with upper frequency.
