Several embodiments of the invention are presented in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1, a smoke value processing method according to a first embodiment of the present invention is applied to a smoke processing apparatus, the smoke processing apparatus is provided with a smoke sensor, and the smoke value processing method includes steps S01 to S03.
Step S01, when the start signal of the smoke processing apparatus is received, it is determined whether the calibration information of the smoke sensor is recorded in the calibration record table.
Wherein the calibration log is stored in a memory of the smoke processing apparatus.
It will be appreciated that when the user turns on the smoke treatment device by pressing a key, remote control, etc., the system will traverse the calibration record table stored in the memory to determine whether the calibration information of the smoke sensor is recorded in the calibration record table.
When it is determined in step S01 that the smoke sensor has been calibrated (there is calibration information), step S02 is executed, and when it is determined in step S01 that the smoke sensor has not been calibrated (there is no calibration information), step S03 is executed.
And step S02, obtaining the calibrated smoke reference value, and judging whether to send a smoke processing instruction to the smoke processing equipment according to the smoke reference value.
The step of determining whether to issue a smoke processing instruction to the smoke processing apparatus according to the smoke reference value may be specifically implemented according to the following steps: and comparing the current smoke value acquired by the smoke sensor with the smoke reference value, and when the difference value of the current smoke value and the smoke reference value is within a preset interval, sending a smoke processing instruction to the smoke processing equipment so as to enable the smoke processing equipment to execute corresponding actions (such as alarming, oil smoke suction and the like).
Step S03, calibrating the smoke sensor according to a preset calibration rule, and recording current calibration information in the calibration record table.
It should be noted that, actually, calibrating the smoke sensor is to test a smoke value actually acquired by the smoke sensor in a smoke-free state, and the smoke value obtained in the calibration process is stored as a smoke-free standard value of the smoke sensor, that is, a smoke reference value is obtained.
Additionally, the current calibration information may include a time of the current calibration to facilitate subsequent queries in the calibration log table as to when the smoke sensor was calibrated.
In summary, in the smoke value processing method in the above embodiment of the present invention, when the smoke processing apparatus is turned on, whether the smoke sensor on the smoke processing apparatus has been calibrated is automatically determined, if not, the smoke sensor is calibrated according to the preset calibration rule, and the smoke reference value obtained by calibration is stored to be used as the standard value of the smoke sensor in the smoke-free state for subsequent smoke determination. Because the smoke reference value set on each smoke processing device is obtained by calibrating the smoke sensor on the smoke processing device, the set smoke reference value is close to the actual standard value of the corresponding smoke sensor in a smokeless state, the reliability of standard value setting is improved undoubtedly, the accuracy of smoke judgment is further improved, and the phenomenon that the smoke processing device is triggered by mistake is avoided.
Referring to fig. 2, a smoke value processing method according to a second embodiment of the present invention is applied to a smoke processing apparatus, wherein a smoke sensor is disposed on the smoke processing apparatus, and the smoke value processing method includes steps S11 to S20.
Step S11, when the start signal of the smoke processing apparatus is received, it is determined whether the calibration information of the smoke sensor is recorded in the calibration record table within a preset time.
For example, when the user turns on the smoke processing device by pressing a key, remotely controlling the smoke processing device, or the like, the smoke processing device may determine whether the calibration record table records the calibration information of the smoke sensor within one year, and if so, it indicates that the smoke sensor has been calibrated within the last year.
When it is determined in step S11 that the calibration information of the smoke sensor is not recorded in the calibration record table within the preset time, which indicates that the smoke sensor has not been calibrated in the near future, steps S12 to S16 are performed, and when it is determined in step S11 that the calibration information of the smoke sensor is recorded in the calibration record table within the preset time, which indicates that the smoke sensor has been calibrated in the near future, step S17 is performed.
And step S12, sending out a calibration environment prompt message to prompt a user to ensure that the smoke treatment equipment is in a smoke-free state.
It will be appreciated that since calibration of the smoke sensor is actually a test of the smoke values actually acquired by the smoke sensor in a smoke-free state, it is necessary to ensure that the smoke treatment apparatus is in a smoke-free state prior to calibration.
In addition, the sending mode of the prompt message includes but is not limited to language playing, alarm prompting, pop-up box display, short message notification, and the like.
For example, when a user opens the range hood to prepare cooking, the range hood judges that the smoke sensors on the range hood have calibration records in the last year, and sends a language play prompt (the prompt content can be 'the range hood needs to be calibrated currently, please ensure that the kitchen is in a smokeless state'), and the user can operate according to the prompt inevitably.
Step S13, reading the smoke value collected by the smoke sensor in the smoke-free state for a predetermined number of times within a predetermined time to obtain a predetermined number of smoke values.
For example, the smoke value acquired by the smoke sensor is read 10 times (once per second) within 10S, so that 10 smoke values actually acquired by the smoke sensor in a smoke-free state are obtained.
And step S14, removing the maximum value and the minimum value in all the smoke values.
For example, the maximum value of the above 10 smoke values is removed and the maximum calibration is performed to leave 8 smoke values, so as to improve the accuracy of the subsequent calculation.
And step S15, averaging the residual quantity of smoke values, and taking the calculated average value as the current smoke reference value.
For example, the remaining 8 smoke values are averaged to obtain the current smoke reference value.
And step S16, storing the current smoke reference value obtained by calibration into Flash, and deleting the smoke reference value obtained by the last calibration from the Flash.
Among them, Flash refers to a Flash memory, which is a long-life nonvolatile (i.e., capable of holding stored data information even when power is off) memory.
It should be noted that each pair of the smoke sensors is calibrated once to obtain a smoke reference value, and when the current smoke reference value is stored in Flash, the smoke reference value obtained by the last calibration is deleted to ensure that only one smoke reference value is stored in Flash, and the smoke reference value is obtained by the last calibration to ensure that the obtaining of the subsequent smoke reference value is not disordered.
Step S17, recording the current calibration information into the calibration record table, where the current calibration information includes the current calibration time.
It is understood that the time of each calibration is recorded in the calibration record table, so as to inquire when the smoke sensor is calibrated in the calibration record table later, and whether the smoke sensor is calibrated within a preset time can be judged according to the calibration time recorded in the calibration record table.
Step S18, sending a calibration completion prompt message to prompt the user that the calibration of the smoke sensor is completed.
For example, when a user receives prompt information of the calibration environment, such as "the range hood needs to be calibrated currently and please ensure that the kitchen is in a smokeless state", the user inevitably ensures that the kitchen is in the smokeless state, after a period of time, the range hood completes calibration of the smoke sensor, at this time, prompt information of calibration completion, such as "the calibration is completed and the range hood can be normally used", is sent, and the user can start to fry dishes according to the prompt.
It can be understood that the phenomenon that a user waits for the calibration of the range hood all the time can be avoided by sending out the calibration completion prompt message.
And step S19, obtaining the calibrated smoke reference value from the Flash.
It is understood that the smoke reference value obtained in step S19 is obtained from the last calibration.
And step S20, judging whether to send a smoke processing instruction to the smoke processing equipment according to the smoke reference value.
Specifically, referring to fig. 3, a flowchart of the step S20 is shown, which includes steps S201 to S203.
Step S201, calculating a difference between the current smoke value collected by the smoke sensor and the smoke reference value to obtain a target difference.
Step S202, judging whether the target difference value is within a preset range.
When it is determined in step S202 that the target difference is within the preset range, indicating that smoke is present, executing step S203, and when it is determined in step S202 that the target difference is not within the preset range, indicating that smoke is not present, not performing the monitoring.
Step S203, sending the smoke processing instruction to the smoke processing device.
It will be appreciated that when the smoke treatment instructions are received by the hardware structure of the smoke treatment apparatus, corresponding actions are carried out to cause the smoke treatment apparatus to respond to the instructions, such as to effect an alarm, to smoke extraction, etc.
For example, when a user starts to cook, a large amount of oil smoke is generated, the difference between the current smoke value acquired by the smoke sensor and the smoke reference value (obtained by the last calibration) inevitably falls within the preset range, and the range hood starts the fan to perform the action of sucking the oil smoke.
Furthermore, in other embodiments, the smoke value processing method may further include: and when the calibration signal of the smoke sensor is received, executing the step of calibrating the smoke sensor according to a preset calibration rule.
It can be understood that, when a user needs to actively calibrate the smoke sensor, the system can acquire a calibration signal of the smoke sensor, automatically calibrate the smoke sensor and store a smoke reference value obtained by calibration into Flash through an electric shock calibration icon (for example, an operation touch screen is arranged on some range hoods, and the calibration icon can be arranged on the operation touch screen) or pressing a calibration entity button.
In summary, in the using process of the smoke sensor, the parameters of the smoke sensor are inevitably changed, so that the smoke value actually acquired by the smoke sensor in the smokeless state is changed, and the smoke reference value obtained by previous calibration is not accurate enough, so that the smoke value processing method in the embodiment calibrates the smoke sensor once every period of time, replaces the smoke reference value obtained by the previous calibration with the smoke reference value obtained by the current calibration, ensures that the smoke reference value stored in Flash is close to the smoke value actually acquired by the smoke sensor in the smokeless state, improves the accuracy of smoke judgment, and avoids the phenomenon of false triggering of the smoke processing equipment.
