The embodiment of the application provides a detection and alarm method for natural gas and combustible gas of a dishwasher, and referring to fig. 1, the method can be executed by electronic equipment, and the main flow of the method is described as follows, including (step S101 to step S103):
step S101: concentration information of a leak gas is obtained, the leak gas including natural gas and other combustible gases.
Specifically, the electronic device obtains the natural gas concentration information or/and the combustible gas concentration information through the electric signals sent by the natural gas sensor and the combustible gas sensor, namely, the electronic device can obtain the concentration information of the leaked gas. When the leaked gas is natural gas, the electronic equipment acquires the natural gas concentration information and the combustible gas concentration information, and when the leaked gas is other combustible gas, the electronic equipment acquires the combustible gas concentration information.
Step S102: and when the concentration reaches the preset concentration, generating alarm information.
Specifically, when the concentration of the leaked gas reaches a preset concentration, the electronic equipment generates alarm information, and the electronic equipment can control an alarm on the dish washer to give out an audible alarm or can send alarm information to the terminal, so that remote alarm is facilitated.
Step S103: leak information of the leak gas is determined based on the concentration information.
Specifically, the leakage information includes a state of change of the leakage gas, a kitchen ventilation state, and a leakage risk level, and step S103 includes (step S10311 to step S1033):
step S1031: and acquiring the detection concentration of the leakage gas at intervals of preset time.
Specifically, the electronic device continuously acquires the detected concentration of the leaked gas, and uses only the detected concentration of the leaked gas acquired within a preset time as a sample to determine the leakage information of the leaked gas.
Step S1032: based on the detected concentrations for every two adjacent preset times, a change state of the leaking gas and a kitchen ventilation state are determined, including (steps Sa to Sc):
step Sa: and comparing the detected concentration at the current moment with the detected concentration at the previous moment, and determining the variation of the detected concentration.
Step Sb: the variation parameter is determined based on the ratio of the variation to the unit variation.
For example, the electronic device obtains a plurality of amounts of change of two adjacent preset times: the 1VOL, 1.2 VOL and 1.5 VOL … … electronic equipment is provided with the unit change amount of 0.1 VOL, and then the electronic equipment calculates the ratio of the change amount to the unit change amount to obtain the change parameters: 10. 12, 15, … …, the electronic device thus processes the variable amount data for further calculation.
Step Sc: based on the plurality of variation parameters, a variation state and a ventilation state of the kitchen are determined, including any one of the following:
if the multiple variation parameters are increased or the variance is zero, the leakage gas is continuously leaked and the kitchen is not ventilated;
if the multiple variation parameters are zero, the leakage speed of the leaked gas and the ventilation speed in the kitchen are balanced, or the leakage of the leaked gas is stopped;
if the plurality of variation parameters are decreasing, the leakage gas leakage speed is smaller than the kitchen ventilation speed.
Specifically, when the variance of the variation parameter is approximately zero, i.e., the concentration of the leak gas in the room is in a steady growth state; when the variation parameter is zero, namely the concentration of the leakage gas in the chamber does not change obviously. The electronic equipment further estimates the change state and ventilation condition of the leaked gas in the kitchen according to the change parameters of the leaked gas.
Step S1033: determining a risk level of leakage based on the changing status of the leakage gas and the kitchen ventilation status, including any one of the following:
if the leaked gas is continuously leaked and the kitchen is not ventilated, determining the dangerous grade as a first grade;
if the leakage speed of the leaked gas and the ventilation speed in the kitchen reach balance or the leakage of the leaked gas is stopped, determining the dangerous grade as a second grade;
if the leakage speed of the leaked gas is smaller than the kitchen ventilation speed, the risk level is determined to be three-level.
Specifically, the electronic equipment determines the dangerous level of leakage according to the change state of the leaked gas and the kitchen ventilation state, so that a user can grasp the specific condition of the leaked gas conveniently.
In another possible implementation manner, the concentration information of the leaked gas includes natural gas concentration information sent by the natural gas sensor and/or combustible gas concentration information sent by the combustible gas sensor, and the method further includes (steps S111 to S13):
step S11: a distance between the natural gas sensor and the combustible gas sensor is determined.
Specifically, the electronic device pre-stores the distance between the natural gas sensor and the combustible gas sensor.
Step S12: determining the type of the leaked gas based on the natural gas concentration information and/or the flammable gas concentration information;
specifically, since the flammable gas sensor can also detect natural gas, when the electronic device obtains the natural gas concentration information and the flammable gas concentration information, the leaking gas includes natural gas; when the electronic equipment only acquires the concentration information of the combustible gas, the leaked gas does not contain natural gas, and the leaked gas is other combustible gas.
Step S13: when the type of the leaking gas is natural gas, an additional risk level is determined based on the natural gas concentration information, the flammable gas concentration information, and the distance, including (step S1311 to step S137):
step S131: and acquiring a first moment when the natural gas concentration reaches a preset concentration.
Step S132: and obtaining a second moment when the concentration of the combustible gas reaches the preset concentration.
Step S133: the kitchen area is obtained.
Specifically, the electronic device may acquire various data according to the above sequence, or may acquire the various data simultaneously, or may acquire the various data in other sequences. Further, the electronic device may obtain a kitchen area entered by the user.
Step S134: the interval time is calculated based on the first time and the second time.
Specifically, if there is a distance between the natural gas sensor and the flammable gas sensor, the two sensors have a time difference in the time when they detect the natural gas, i.e., the difference between the first time and the second time is the interval time.
Step S135: the quotient of the distance and the interval time is calculated to obtain the initial diffusion speed.
Step S136: determining an evaluation index based on the magnitude of the initial diffusion rate and the magnitude of the kitchen area;
specifically, the electronic equipment is preset with a plurality of first grades of initial diffusion speed, and the electronic equipment determines that the electronic equipment belongs to a certain first grade according to the initial diffusion speed; the electronic equipment is preset with a plurality of second grades of the kitchen area, and the electronic equipment determines that the electronic equipment belongs to a certain second grade according to the kitchen area, wherein the smaller the kitchen area is, the higher the second grade is. The electronic device multiplies the first level with the second level, and calculates an evaluation index.
Step S137: additional risk levels are classified based on the assessment index.
Specifically, the electronic device presets a plurality of additional risk levels, and the higher the evaluation index is, the higher the additional risk level is, so that a user can conveniently judge the gas leakage risk condition according to the additional risk level.
