Detailed Description
In order to make those skilled in the art better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flow chart of a safety monitoring method for a cooking device according to an embodiment of the present invention, the safety monitoring method is suitable for monitoring a connection state of a connector in the cooking device, and then finding a situation of poor connection of the connector, and taking a protective measure to avoid safety problems such as equipment damage and even fire caused by poor connection. The safety monitoring method may be performed by a processor in the cooking appliance. As shown in fig. 1, the security monitoring method includes the following steps:
s101, acquiring the actual temperature of an area where a connector in the cooking equipment is located at intervals of a first preset time.
Wherein the connector is used for connecting a wire and a load in the cooking apparatus. As described above, the connector can connect the power supply line and the circuit board, and connect the cable and the heating load, and the like. By way of example, the connectors include, but are not limited to, the following types of connectors: 250 male, 187 male, VH female, and crimp connectors, etc. The inserting sheet has low cost and convenient installation and operation, and is one of the commonly used connectors.
The first preset time may be a small time interval, for example, 5s or 10s, so that the real temperature of the area where the connector is located in the cooking apparatus is obtained every first preset time, and the real temperature of the area where the connector is located may be obtained in real time. Specifically, a temperature sensor may be used to collect an actual temperature of an area where the connector is located, and the actual temperature may be sent to the processor, so that the processor may obtain the actual temperature of the area where the connector is located in real time. Since the connector generates heat when the connector is poorly connected, the connection state of the connector can be determined by detecting the temperature at this point.
For example, the characteristics of the sensor material or electronic components in the Temperature sensor include, but are not limited to, a Negative Temperature Coefficient (NTC) thermistor and a thermocouple, and the actual Temperature of the area where the connector is located may be collected by means of infrared Temperature measurement or the like. Optionally, the temperature sensor is disposed as close to the connector as possible, for example, the temperature sensor may be soldered to a circuit board, may be fixed to the connector, and may be fixed to the wire harness through a heat shrink tube, so as to improve accuracy and reliability of the temperature acquisition result.
S102, determining a current temperature value based on the actual temperature acquired within a second preset time; the second preset time is greater than the first preset time.
The second preset time may be set according to a requirement, which is not limited in the embodiment of the present invention, as long as the second preset time is greater than the first preset time. For example, the second preset time may be 3min or 5min.
The current temperature value refers to a temperature of the connector corresponding to the current second preset time. Specifically, the cooking process of the cooking device can be divided into a plurality of second preset times, each second preset time can acquire a plurality of actual temperatures, the temperature values of the connectors corresponding to the second preset times can be determined based on the corresponding actual temperatures, and then the connection state of the contactor can be judged according to the temperature values.
For example, after the cooking device is started, an actual temperature value of an area where the connector is located may be obtained in real time, after a second preset time elapses, a current temperature value is determined based on the actual temperature obtained in the second preset time, and the subsequent S103 of determining the connection state of the connector is performed, if it is determined that the connector is not connected well, S104 is performed, if it is determined that the connector is connected well, a next step cycle of the second preset time is performed, and so on, so as to ensure the safety of the whole cooking process of the cooking device. It is understood that the cooking process and the actual temperature acquisition are not interrupted but performed simultaneously while the data processing and analysis processes of S102 to S103 are performed, and since the time for the data processing and analysis processes is short, even if it is determined that the connector is poorly connected, a large adverse effect is not caused.
For example, a certain actual temperature (for example, the maximum actual temperature) obtained within the second preset time may be used as the current temperature value, or the current temperature value may be determined in other manners.
S103, judging the current connection state of the connector according to the current temperature value and the reference temperature value.
The current connection state is the current stage, or the connection state of the connector within the second preset time that has just elapsed.
The reference temperature value is a temperature reference basis for judging the connection state of the connector. By comparing the current temperature value with the reference temperature value, whether the connector is poorly connected can be judged. In one embodiment, the reference temperature value may be a fixed value, and if the current temperature value reaches the reference temperature value, it may be determined that the connector is not connected well. Of course, this embodiment is merely illustrative and not limiting.
And S104, when the connector is judged to be in poor connection, controlling the cooking device to stop working.
Illustratively, when the connector is judged to be connected badly, the cooking equipment can be controlled to stop working and timely maintained in a power-off mode, and bad influence is avoided.
To sum up, according to the technical scheme of the embodiment of the invention, the actual temperature of the area where the connector in the cooking equipment is located is obtained every first preset time, the current temperature value is determined based on the actual temperature obtained in the second preset time, the current connection state of the connector is judged according to the current temperature value and the reference temperature value, and when the connector is judged to be in poor connection, the cooking equipment is controlled to stop working.
Fig. 2 is a schematic flow chart of another safety monitoring method for a cooking device according to an embodiment of the present invention, and on the basis of the above embodiment, determination of a reference temperature value is mainly improved, and details of the same parts as those in the above embodiment are omitted. As shown in fig. 2, in this embodiment, the security monitoring method includes the following steps:
s201, acquiring the actual temperature of an area where a connector in the cooking equipment is located at intervals of a first preset time.
S202, determining a current temperature value based on the actual temperature acquired within the second preset time; the second preset time is greater than the first preset time.
Alternatively, the current temperature value may be determined by: and calculating the average value of all the actual temperatures acquired within the second preset time, and determining the average value as the current temperature value. Compared with the method for judging the connection state of the connector by adopting the temperature at a certain moment, the method for judging the connection state of the connector by adopting the average value of the actual temperature collected in the second preset time as the current temperature value can make the judgment result more accurate and reliable.
And S203, determining a reference temperature value according to the operation times of the current cooking mode.
Wherein, the current cooking mode is the operation mode of the cooking equipment in the current cooking process. The temperature of the area where the connector is located has a certain relation with the cooking mode of the cooking equipment, the power of the cooking equipment is different, the temperature of the area where the connector is located can change along with the temperature, and at the moment, the reference temperature value can be determined according to the cooking mode. In addition, season, region, installation environment etc. also can influence the temperature of the regional of connector place, and when cooking equipment's operational environment changed, reference temperature value also can take place certain change, and at this moment, reference temperature value is not fixed value. In view of this, in order to further improve the accuracy of the determination result, the present embodiment determines the reference temperature value according to the operation times of the current cooking mode, in other words, when the operation times of the current cooking mode are different, different reference temperature values are selected.
Alternatively, the reference temperature value may be determined according to whether the current cooking mode is the first operation. Specifically, if the current cooking mode is not the initial operation, the reference temperature value can be determined according to the historical temperature data of the mode which is operated recently, so that compared with the fixed reference temperature value, the accuracy of the reference temperature value can be further improved, and the interference of the cooking mode and the environmental change can be eliminated. If the current cooking mode is the initial operation, a fixed temperature threshold value can be selected as a reference temperature value because no historical temperature data is used as a reference.
In a specific embodiment, optionally, determining the reference temperature value according to the number of operations of the current cooking mode may include the following steps:
a. and judging whether the current cooking mode is the initial operation or not.
b. If yes, the reference temperature value is determined to be a first preset threshold value.
c. If not, determining that the reference temperature value comprises a first preset threshold value, a historical temperature value and a second preset threshold value; the second preset threshold is smaller than the first preset threshold, both the first preset threshold and the second preset threshold are fixed values, and the historical temperature value is a non-fixed value.
The first preset threshold may be, for example, a maximum tolerable temperature of the connector, and if the current cooking mode is the initial operation, the maximum tolerable temperature of the connector may be used as a reference temperature value, and the connection state of the connector is determined by determining whether the current temperature exceeds the maximum tolerable temperature of the connector.
The historical temperature value refers to a temperature value corresponding to a second preset time when the current cooking mode is operated before the current cooking mode is operated. Specifically, when the cooking modes are the same, the cooking time lengths are the same, so that the historical cooking process includes a plurality of second preset times in one-to-one correspondence with the current cooking process, and the temperature value determined by the second preset time in the historical cooking process is the historical temperature value corresponding to the current second preset time. It should be noted that the historical temperature value may be determined according to a temperature value corresponding to a second preset time when the same mode is operated for a plurality of times before, and is not limited to a certain historical cooking process.
In a specific embodiment, optionally, the historical temperature value may be determined according to the following steps:
a. and acquiring historical current temperature values under the working condition that the previous n times are the same as the current cooking mode.
b. And determining the average value of the n historical current temperature values as the historical temperature value.
Wherein n is less than the number of operations of the current cooking mode. As can be appreciated, n ≧ 1. It can be further understood that if the historical temperature values are determined according to the historical temperature data of all the current cooking modes operated before the current cooking mode, the data volume is too large, and especially, the data volume is larger as the cooking equipment is used for a longer time, so that only the historical temperature data of the same cooking mode which is a few times before the current cooking mode is operated at this time can be selected. Illustratively, 1 ≦ n ≦ 10.
And the historical current temperature value is the temperature value determined in the time period corresponding to the current second preset time in the historical cooking process which is operated in the current cooking mode before the current cooking process. It will be appreciated that the historical current temperature value is determined in the same manner as the current temperature value, and is only distinguished when the historical current temperature value is in the past, and when the current temperature value is in progress. Specifically, the historical current temperature values may be stored in the memory while the historical cooking process is in progress, so that in the current cooking process, the processor calls (acquires) the historical current temperature values of the previous cooking process n times to obtain n historical current temperature values. Furthermore, the accuracy of the historical temperature value can be improved by calculating the average value of the n historical current temperature values and determining the average value as the historical temperature value.
For example, taking n =2, the cooking time of the current cooking mode is 15min, and the second preset time is 5min, in the current cooking process, the historical temperature value corresponding to each second preset time may be determined according to the following steps:
acquiring an average value T2_1 of actual temperatures acquired in the first 5min in the previous two cooking processes;
acquiring an average value T2_2 of actual temperatures acquired in the second 5min in the previous two cooking processes;
acquiring an average value T2_3 of actual temperatures acquired in the third 5min in the previous two cooking processes;
acquiring an average value T1_1 of actual temperatures acquired in the first 5min in the previous cooking process;
acquiring an average value T1_2 of actual temperatures acquired in the second 5min in the previous cooking process;
acquiring an average value T1_3 of actual temperatures acquired in the third 5min in the previous cooking process;
in the current cooking process, the historical temperature value corresponding to the first 5min is T _ A1= (T1 _1+ T2_1)/2; similarly, the historical temperature value corresponding to the second 5min is T _ A2= (T1 _2+ T2 \/2); the third historical temperature value corresponding to 5min is T _ A3= (T1 _3+ T2 \/3)/2.
The second preset threshold is a temperature threshold of a difference value between the current temperature value and the historical temperature value. It can be understood that, under the same cooking mode, the temperature variation conditions of the corresponding time periods in the cooking process are basically consistent, and if the difference value between the current temperature value and the historical temperature value is too large, the connector may be poorly connected. The specific value of the second preset threshold may be set reasonably according to actual conditions, which is not limited in the embodiment of the present invention.
In this embodiment, if the current cooking mode is not the first time operation, the reference temperature value is set to include a first preset threshold, a historical temperature value, and a second preset threshold, so that the connection state of the connector can be determined according to the magnitude relationship between the current temperature value and the first preset threshold, and the magnitude relationship between the difference between the current temperature value and the historical temperature value and the second preset threshold, and the accuracy of the determination result is further improved.
And S204, judging the current connection state of the connector according to the current temperature value and the reference temperature value.
Specifically, when the current cooking mode is operated for the first time, the reference temperature value is a first preset threshold value, and at this moment, the current connection state of the connector is judged according to the current temperature value and the reference temperature value, and can be judged in the following way: if the current temperature value is larger than or equal to a first preset threshold value, judging that the connector is not well connected, otherwise, judging that the connector is well connected.
Specifically, when the current cooking mode is not operated for the first time, the reference temperature value includes a first preset threshold value, a historical temperature value and a second preset threshold value, and at this time, the current connection state of the connector is judged according to the current temperature value and the reference temperature value, and the current connection state can be judged in the following manner: if the difference value between the current temperature value and the historical temperature value is larger than or equal to a second preset threshold value, and/or if the current temperature value is larger than or equal to a first preset threshold value, judging that the connector is not well connected, otherwise, judging that the connector is well connected. In other words, if at least one of the difference between the current temperature value and the historical temperature value is greater than or equal to the second preset threshold value and the current temperature value is greater than or equal to the first preset threshold value, the connector is determined to be in poor connection, and if the difference is not greater than the first preset threshold value, the connector is determined to be in good connection.
If the historical temperature value is close to the first preset threshold value, even if the difference value between the current temperature value and the historical temperature value is smaller than the second preset threshold value, the situation that the current temperature value is larger than the first preset threshold value may occur, at the moment, the temperature at the connector is too high, the connector is judged to be badly connected, and protective measures are taken in time. Similarly, even if the current temperature value is smaller than the first preset threshold, a situation that the difference value between the current temperature value and the historical temperature value is larger than or equal to the second preset threshold may occur, at this time, because the difference between the current temperature value and the historical temperature value is larger, a situation that the connector is connected badly may also occur, the connector is determined to be connected badly, and a protective measure is taken in time to prevent the occurrence of the badly connected connector. In summary, when the current cooking mode is not the first time operation, the embodiment of the invention adopts double criteria to judge whether the connector is well connected, so that the accuracy of the judgment result can be further improved, and the occurrence of potential safety hazards can be effectively avoided.
And S205, when the connector is judged to be in poor connection, controlling the cooking equipment to stop working, and sending an alarm signal to a user.
Specifically, when the connector is judged to be in poor connection, besides controlling the cooking equipment to stop working, the cooking equipment can also send an alarm signal to a user so that the user can know the condition that the connector is in poor connection and maintain in time. For example, an alarm in the cooking apparatus may be controlled to send an alarm signal to the user.
Fig. 3 is a specific flowchart of a safety monitoring method for a cooking device according to an embodiment of the present invention, in fig. 3, T represents a current temperature value, and T _ a represents a historical temperature value, which are not described herein again, and fig. 3 illustrates an example where the first preset threshold is 80 ℃ and the second preset threshold is 10 ℃. As shown in fig. 3, in this embodiment, the security monitoring method includes the following steps: after cooking starts, firstly judging whether the cooking mode is a first operation; if the cooking mode is the first operation, judging whether the current temperature value t is greater than or equal to 80 ℃, if so, indicating that the connector is poorly connected, closing the equipment and giving an alarm, and if not, indicating that the connector is well connected and can normally work; if the cooking mode is not the first operation, firstly, judging whether the difference value between the current temperature value and the historical temperature value is larger than or equal to 10 ℃, if so, indicating that the connector is poorly connected, closing the equipment and giving an alarm, if not, continuously judging whether the current temperature value t is larger than or equal to 80 ℃, if so, indicating that the connector is poorly connected, closing the equipment and giving an alarm, and if not, indicating that the connector is well connected and can normally work. It can be understood that, if the connection state of the connector is good at the current stage (i.e. within the current second preset time), the judgment of the next second preset time is continued until the cooking apparatus is finished.
Fig. 4 is a specific flowchart of a safety monitoring method for a cooking apparatus according to an embodiment of the present invention, and the difference between fig. 4 and fig. 3 is only that the cooking mode is not operated for the first time, the sequence of determining whether the current temperature value t is greater than or equal to 80 ℃ and the sequence of determining whether the difference between the current temperature value and the historical temperature value is greater than or equal to 10 ℃ is different, and the specific flow is not explained herein too much. According to the arrangement, the connector is determined to be well connected only when the current temperature does not exceed the first preset threshold value and the difference value between the current temperature and the historical temperature value is within a small range, the possibility of misjudgment can be reduced, and the accuracy of the judgment result is improved.
