In this embodiment, the door magnetic sensor is installed on the refrigerator body and the door body. The door sensor comprises a wireless door sensor body and a permanent magnet. The permanent magnet is installed on the door body, and the wireless door magnetism main part is installed on the box. The permanent magnet rotates along with the door body.
In an embodiment of the present invention, a door sensor is located on a refrigerator, as shown in fig. 1, and the method includes:
s10 collects the report information of the door magnetic sensor.
S20, analyzing the activity state information of the person according to the report information of the door sensor.

In the above embodiment, the door sensor is mounted on the refrigerator. When the refrigerator door is opened from the closed state, the door magnetic sensor emits a signal. The door magnetic sensor also emits a signal when the refrigerator door is moved from an open state to a closed state. The change of the state of the refrigerator door is realized by human control. That is, when the state of the refrigerator door is changed, it indicates that a person is operating. When people cook, people usually use a refrigerator. Preferably, in the cooking time period, the report information transmitted by the door magnetic sensor is acquired, so as to obtain whether the activity state information of the analyst is normal. If not, warning information is sent out. This alerts children or others that the solitary old person may be dangerous. The embodiment can improve the personal safety of the old.
Preferably, the acquiring the report information of the door sensor includes:
detecting whether state data of a reed switch in the door sensor are changed or not, if not, sending no report information, and if so, sending report information; the reed switch changing state comprises that a patch in the reed switch is changed from a connected state to a disconnected state, and the patch in the reed switch is changed from the disconnected state to the connected state;
and receiving the sent reporting information.
In the above embodiment, according to whether the reed switch has changed state data, if the reed switch has no changed state data, the alarm signal is not sent, and the radio signal is not sent. The wireless door sensor main body does not emit radio signals and is in a low power consumption state, so that power saving is facilitated. The reed switch changing state comprises that the patch in the reed switch is changed from a connection state to a disconnection state, and the patch in the reed switch is changed from the disconnection state to the connection state. The patch in the reed switch changes from the connected state to the disconnected state, meaning that the refrigerator door is opened. The patch in the reed switch changes from the disconnected state to the connected state, meaning that the refrigerator door is closed. When the state of the refrigerator door is not changed, for example, the refrigerator door is always in an open state or a closed state, the communication module enters a sleep state, and the power consumption is low at the moment. When the state of the refrigerator door changes, the communication module is awakened when needing to send data, and the power consumption is larger at the moment. Therefore, the wireless door magnet main body is not always in a state of transmitting a radio signal, so that the power consumption is greatly saved, and the frequency of replacing the battery is reduced.
Preferably, the sending alarm information includes: according to the reed switch change state data, sending alarm information within a second, and then stopping sending the alarm information; said a < 2 seconds. And when the state of the reed switch changes, sending alarm information. In the prior art, the alarm information sending time is long, and usually, the sending of the alarm information is stopped by human interference. In this preferred embodiment, the time for sending the alarm information is limited to 2 seconds. After the time reaches the preset time, the preferred embodiment stops transmitting the radio signal. The time for sending alarm information is short, and the purpose of saving electricity is achieved. And after the alarm information is sent, entering a low power consumption mode.
Preferably, as shown in fig. 2, the acquiring the report information of the door sensor according to another embodiment of the present invention includes:
s101, initializing each module in the door sensor MCU;

The door sensor comprises a wireless door sensor body and a permanent magnet. The wireless door sensor main body comprises an MCU, a communication module, a battery and a reed switch. The MCU is used for receiving the interrupt signal, controlling the module to receive and transmit and process various business logics. The communication module is used for transmitting and receiving data to the nb base station. And the battery is used for supplying power. The reed switch is used for outputting a switching value signal by approaching and departing from the permanent magnet. In this embodiment, first, each peripheral of the MCU in the door sensor and the register are configured. Then, a communication instruction is configured, and an AT instruction is sent to the NB communication module through the MCU. And then, whether the communication module accesses the network is detected. During the process of configuring the AT command, the communication module returns an information confirmation. After the communication module is connected to the network, whether the reed pipe in the door sensor has changed state data or not is detected.
Preferably, the intelligent control method of the door, as shown in fig. 3, further includes:
s105, acquiring the real-time state of the reed switch at a preset time point or the state change times of the reed switch in a preset time period according to the preset time point, and uploading the state change times to a platform; and meanwhile, returning to the step of initializing each module in the door sensor MCU.
This step implements a timer wakeup function. For example, the program may set that the communication module is awakened from sleep at 0 point (or 12 points) every day, and reports the state of the door magnet switch or the number of times of switching. And after the communication module is awakened, initializing each module again. The communication module is awakened through the timer, so that the working time of the communication module is reduced, and the purpose of saving power is achieved.
As an example, when the refrigerator door is in a closed state, the communication module does not transmit a radio signal, and power consumption is only a few microamps. When the refrigerator door is opened, the communication module immediately transmits a wireless alarm signal for about 1 second and then automatically stops. At this time, the alarm signal is not transmitted even if the refrigerator door is opened all the time.
In the above example, the report information of the door sensor includes the number of times of opening and closing the refrigerator and the corresponding time point. Preferably, the sending out the warning information according to the activity state information of the person includes:
s301, acquiring a preset activity state information table;
s302, comparing the activity state information of the person with information in a preset activity state information table;
s303, sending out warning information according to the comparison result.
The system is provided with a preset activity state information table. And comparing the acquired activity state information of the person with a preset activity state information table. And obtaining the warning information according to the comparison result. For example: the information in the preset activity state information table is as follows: the time period is 10: 30-12: 30, and the total times of opening and closing the refrigerator door are 2 times. If the collected report information of the door magnetic sensor shows that no action is performed in the time period, warning information is sent out. If the collected report information of the door magnetic sensor shows that the total times of opening and closing the refrigerator door in the time period is 4, no warning information is sent out.
