All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The appearances of the phrases "first," "second," and "third," or the like, in the specification, claims, and figures are not necessarily all referring to the particular order in which they are presented. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
The invention discloses a method for controlling the work of an electric appliance based on the Internet of things, which comprises the following steps: the method comprises the steps that an ammeter sends requests of working states of electric appliances to sensors, wherein the sensors correspond to household electric appliances one to one; the sensor is used for monitoring the temperature of the corresponding household appliance; the ammeter receives the information fed back by each sensor and determines a target electric appliance in an operating state according to the fed back information; the ammeter acquires the temperature of the target electric appliance at the first moment and the temperature of the target electric appliance at the second moment through the sensor corresponding to the target electric appliance; the ammeter judges whether an abnormally operated electric appliance exists in the target electric appliances or not according to the temperature of the first moment target electric appliance and the temperature of the second moment target electric appliance; and when the electric appliance which runs abnormally is judged to exist, the electric meter cuts off the circuit of the abnormal household electric appliance and sends an alarm prompt to the user.
Referring to fig. 1, fig. 1 is a method for controlling an electric appliance to work based on an internet of things according to an embodiment of the present invention. As shown in fig. 1, a method for controlling an operation of an electrical appliance based on an internet of things according to an embodiment of the present invention includes the following steps:
s101, the electric meter sends a request of the working state of the electric appliance to each sensor, and the sensors correspond to the household electric appliances one by one.
The electric meter comprises a processor, a transceiver and a display screen. The transceiver can receive information from a user and transmit information, and the processor can execute the method according to pre-stored instructions.
The home appliances include a washing machine, a refrigerator, a microwave oven, an air conditioner, etc. The sensor may be mounted inside the household appliance, such as near the motor; the sensor can also be arranged near a heat dissipation port of the electric appliance and can also be arranged near a heating device of the electric appliance. The sensor is used for monitoring the temperature of the corresponding household appliance.
It should be noted that the electric meter may be connected to each sensor, or may be connected to each sensor through a relay, for example, a sensor with higher power may serve as a relay, and a sensor closer to the electric meter may serve as a relay.
For example, the electric meter determines an identifier of each sensor according to the sensor list, and sends a request for establishing connection to each sensor according to the identifier of each sensor; after receiving a request for establishing connection sent by an ammeter, a sensor sends feedback information for agreeing to establish connection, wherein the feedback information comprises identification and position information of the sensor; the ammeter calculates the distance between each sensor and the ammeter according to the position information fed back by each sensor, and the ammeter sets the sensors with the distances smaller than a preset distance as relay points; and the electric meter determines a layered transmission network according to the relay point and sends the layered transmission network to each sensor. For example, 100 sensors are distributed in a villa, the electric meter determines 10 relay points, and determines the information transmission range for each relay point, for example, if the electric meter sends an information acquisition request to 100 sensors, the electric meter will first send to 10 relay points, and then each relay point sends to the sensor in its own range. For example, the No. 1 sensor is responsible for information transmission with the No. 2-10 sensors.
In addition, in order to determine that each sensor is in an activated state, it is necessary to confirm the state of each sensor according to a preset time interval. Optionally, before the electric meter sends a request for the operating state of the electric appliance to each sensor, the method further includes: the electric meter acquires the identifier of each sensor from the sensor management table; the ammeter sends heartbeat information to each sensor according to the identifier of each sensor so as to determine whether each sensor is in an on state; and when detecting that each sensor is in an on state, sending a request of sending the working state of the electric appliance to each sensor by the electric meter to each sensor.
For example, the content of the heartbeat information is a digital signature of the electric meter, after the sensor authenticates the digital signature by using the public key of the electric meter, if the authentication is successful, the information encrypted by the public key is fed back, and the electric meter performs decryption verification.
For example, the heartbeat message may be a simple predetermined string, such as 111111, and the sensor receives the string and then feeds back a predetermined string 000000, if the meter receives the string, it indicates that the meter is in the on state.
Optionally, when it is determined that a sensor which does not perform feedback exists, it is determined that the sensor is abnormal, and the sensor may be dead, may be dead of a battery, or may be unable to be started due to a fault, at this time, a restart instruction may be sent to the abnormal sensor, and if the restart is successful, heartbeat information is sent to perform communication.
Optionally, when it is detected that there is a sensor in a sleep state, acquiring a use duration of the sensor in the sleep state; when the service time of the sensor in the dormant state is longer than a preset time, the ammeter determines that the battery of the sensor in the dormant state is exhausted; the ammeter sends a prompt to the user to enable the user to perform battery replacement on the sensor in the dormant state.
And S102, the electric meter receives the information fed back by each sensor and determines the target electric appliance in the running state according to the fed back information.
It is understood that the amount of heat emitted when the appliance is in the on state is different from the amount of heat emitted when the appliance is in the off state.
It should be noted that if an appliance is in the off state, the temperature monitored by the sensor should be approximately equal to room temperature. If an appliance is in operation, the temperature monitored by the sensor should be greater than room temperature.
And S103, the ammeter acquires the temperature of the target electric appliance at the first moment and the temperature of the target electric appliance at the second moment through the sensor corresponding to the target electric appliance.
Wherein the first time and the second time are different times. The time interval between the first time and the second time may be set by the default of the electric meter, may also be set manually, and may also be set according to the type of the electric appliance. For example, the time intervals for monitoring high-power electrical appliances (air conditioners, washing machines, etc.) are small, for example, every 15 seconds, 20 seconds or 30 seconds (seconds); for example, the time interval for monitoring the low-power electric appliance (such as a fan, etc.) is relatively large, and can be in the order of minutes (such as 1 minute, 3 minutes, etc.).
And S104, the ammeter judges whether an abnormally operated electric appliance exists in the target electric appliances according to the temperature of the first-time target electric appliance and the temperature of the second-time target electric appliance.
Optionally, the determining, by the electric meter, whether an electrical appliance which operates abnormally exists in the target electrical appliance according to the temperature of the target electrical appliance at the first time and the temperature of the target electrical appliance at the second time includes: the ammeter subtracts the temperature of the first time target electrical appliance from the temperature of the second time target electrical appliance to obtain a temperature difference value; the ammeter calculates the percentage of temperature rise according to the temperature difference and the temperature of the target electric appliance at the first moment; and when the percentage of the temperature rise is greater than the preset percentage, determining that the abnormally operated electric appliance exists in the target electric appliances. It is understood that the preset percentages are different for different types of appliances. If the heat dissipation capacity of some electrical appliances is large, the preset percentage is large; some appliances dissipate less heat, and the predetermined percentage is less.
Optionally, the determining, by the electric meter, whether an electrical appliance which operates abnormally exists in the target electrical appliance according to the temperature of the target electrical appliance at the first time and the temperature of the target electrical appliance at the second time includes: the ammeter judges whether the temperature of the target electric appliance at the first moment is within a preset temperature range or not; if the temperature of the target electrical appliance at the first moment exceeds the preset temperature range, judging whether the temperature of the target electrical appliance at the second moment is within the preset temperature range; and if the temperature of the target electrical appliance still exceeds the preset temperature range at the second moment, determining that the target electrical appliance is an electrical appliance which operates abnormally. It can be understood that the preset temperature ranges are different for different types of electrical appliances.
And S105, when the electric appliance which runs abnormally is judged to exist, the electric meter cuts off the circuit of the abnormal household electric appliance and sends an alarm prompt to the user.
Wherein, the alarm can be given by voice or vibration.
It can be seen that in the scheme of the embodiment of the invention, the ammeter sends the request of the working state of the electric appliance to each sensor, and the sensors correspond to the household electric appliances one to one; the sensor is used for monitoring the temperature of the corresponding household appliance; the ammeter receives the information fed back by each sensor and determines a target electric appliance in an operating state according to the fed back information; the ammeter acquires the temperature of the target electric appliance at the first moment and the temperature of the target electric appliance at the second moment through the sensor corresponding to the target electric appliance; the ammeter judges whether an abnormally operated electric appliance exists in the target electric appliances or not according to the temperature of the first moment target electric appliance and the temperature of the second moment target electric appliance; and when the electric appliance which runs abnormally is judged to exist, the electric meter cuts off the circuit of the abnormal household electric appliance and sends an alarm prompt to the user. Therefore, by implementing the technical scheme provided by the invention, whether the electrical appliance is abnormal or not can be determined according to the use state of each electrical appliance and the difference value of the temperatures at different moments, and if the electrical appliance is determined to be abnormal, the circuit is cut off and an alarm prompt is sent to a user so that the user can take remedial measures, thereby avoiding causing greater loss to the user.

optionally, when it is detected that there is a sensor in a sleep state, acquiring a use duration of the sensor in the sleep state; when the service time of the sensor in the dormant state is longer than a preset time, the ammeter determines that the battery of the sensor in the dormant state is exhausted; the ammeter sends a prompt to the user to enable the user to perform battery replacement on the sensor in the dormant state.
S204, the ammeter receives the information fed back by each sensor and determines a target electric appliance in an operating state according to the fed back information;
s205, the ammeter acquires the temperature of the target electric appliance at the first moment and the temperature of the target electric appliance at the second moment through the sensor corresponding to the target electric appliance;
s206, the ammeter subtracts the temperature of the first time target electrical appliance from the temperature of the second time target electrical appliance to obtain a temperature difference value;
s207, the ammeter calculates the temperature rise percentage according to the temperature difference and the temperature of the target electric appliance at the first moment;
and S208, when the percentage of the temperature rise is larger than the preset percentage, determining that the abnormally operated electric appliance exists in the target electric appliances.
And S209, when the electric appliance which runs abnormally is judged to exist, the electric meter cuts off the circuit of the abnormal household electric appliance and sends an alarm prompt to the user.
