[0010] Determine whether the duration is greater than a preset threshold, and obtain a second determination result;

[0011] If the second judgment result is yes, a door loosening message is sent.

[0012] Usually, the door loose information is sent to alert the user, and the user can stop the car in a safe section to check whether the door is locked. Generally, the door loose information is sent continuously until the door lock detection signal is detected.

[0013] As a further improvement of the present invention, it further includes: if the first judgment result is that the RFID reading and writing device reads the target RFID electronic tag information, determining that the door remains locked.

[0014] As a further improvement of the present invention, it further comprises: if the second judgment result is no, determining that the door remains locked.

[0015] As a further improvement of the present invention, the target RFID electronic tag is arranged on a vehicle door or a vehicle door frame, and the target RFID electronic tag has a first electrode contact and a second electrode contact;

[0016] Among them, when the door is locked, the first electrode contact and the second electrode contact are connected, and the chip circuit in the target RFID electronic tag is connected; when the door is loose, the first electrode contact and the second electrode contact are not connected, and the chip circuit in the target RFID electronic tag is not connected.

[0031] Beneficial effects:

[0032] The present invention first responds to the door lock detection signal and controls the RFID reading device to start. If the target RFID electronic tag information is identified, the door lock detection verification is passed. When it is detected that the vehicle is in a driving state, the RFID reading and writing device is controlled to read the target RFID electronic tag information, and at the same time, it is determined whether the RFID reading and writing device has read the target RFID electronic tag information. If the RFID reading and writing device does not read the target RFID electronic tag information, the duration of not reading the target RFID electronic tag information is obtained, and it is continued to be determined whether the duration is greater than a preset threshold. If so, the door loose information is sent to solve the problem that the door is not securely locked on the way, or the door is loose due to vibration, which easily causes the risk of cargo falling and cannot be monitored.

[0037] like Figure 1 As shown, Figure 1 This is a flow chart of a door status detection method according to an embodiment of the present invention;

[0038] Reference Figure 1 , a door state detection method proposed in an embodiment of the present invention includes:

[0039] S10: In response to the door locking detection signal, controlling the RFID reading device to start;

[0040] The door lock detection signal is usually verified before the vehicle drives. It can be that after the goods are loaded into the car, the system server sends a message that the goods loading is completed, and the door lock detection signal is generated immediately. Then the RFID reading device is controlled to start and whether it can identify the target RFID electronic tag information, and determine whether the door status detection is verified before the vehicle starts.

[0041] The door lock detection signal can also be sent by the user to the server through the terminal after the user detects that the car door is locked, and the detection system starts to verify whether the RFID device and the target RFID electronic tag are working properly so as to carry out the subsequent detection logic.

[0042] S20: If the target RFID electronic tag information is identified, the door lock detection verification is passed;

[0043] In addition, the passing of the door locking test verification can also indicate that the target RFID reader is normal, and after the door is locked, the target RFID electronic tag information can be sent to the RFID reader. It can also indicate that the subsequent door loosening and locking steps can be performed.

[0044] In some embodiments, Figures 2 to 3 As shown, the target RFID electronic tag is arranged on a vehicle door or a vehicle door frame, and the target RFID electronic tag has a first electrode contact 1 and a second electrode contact 2;

[0045] Among them, when the door is locked, the first electrode contact 1 and the second electrode contact 2 are connected, and the chip circuit in the target RFID electronic tag is connected; when the door is loose, the first electrode contact 1 and the second electrode contact 3 are not connected, and the chip circuit in the target RFID electronic tag is not connected.

[0046] S30: Detecting that the vehicle is in a driving state, controlling the RFID reading and writing device to read the target RFID electronic tag information;

[0047] After the door lock detection verification is passed, the door is in a locked state. After the door is started, it enters the driving state. The target RFID electronic tag information can be read in real time by controlling the RFID reader / writer device, or the RFID reader / writer device can be controlled to read the target RFID electronic tag information by setting the frequency / setting the time to enter step S40.

[0048] In some embodiments, it further comprises:

[0049] After the door lock detection verification is passed, the RFID reading and writing device is controlled to be turned off;

[0050] When it is detected that the vehicle enters a bumpy road section, the vehicle speed is greater than a set speed, or the door vibration parameter is greater than a set parameter, the RFID reading and writing device is controlled to turn on;

[0051] The step of determining whether the RFID reader / writer has read the target RFID electronic tag information to obtain a first determination result is performed.

[0052] Usually, after the door lock detection verification is passed, the RFID reading and writing device is controlled to be turned off to save power. For some logistics transportations with long distances and long transportation times, it is necessary to reasonably control the working frequency / working time of the RFID reading and writing device.

[0053] The monitoring section can be determined according to the transportation route of the goods. The monitoring section is a bumpy section, which is a historically marked section on the transportation route where the road surface is uneven and goods are often lost. This can locate the start time of the RFID reading and writing equipment to save energy and electricity. The RFID reading and writing equipment can also be started to monitor the door tightness status information when the driving speed is too fast. On the one hand, it can avoid the loss of goods falling due to excessive speed, which is difficult to find and stop loss. On the other hand, it can avoid traffic accidents caused by loose doors and goods falling.

[0054] S40: Determine whether the RFID reader / writer has read the target RFID electronic tag information, and obtain a first determination result;

[0055] If the door lock detection verification passes, it means that the RFID reader can read the target RFID electronic tag information. If the door lock detection verification fails, it means that the RFID reader cannot read the target RFID electronic tag information. Therefore, the door status information can be preliminarily determined by judging whether the RFID reader reads the target RFID electronic tag information. The door status information includes whether the door is locked and whether the door is loose.

[0056] S50: If the first judgment result is that the RFID reader / writer fails to read the target RFID electronic tag information, obtain a duration of failure to read the target RFID electronic tag information;

[0057] After the RFID reader / writer fails to read the target RFID electronic tag information, it is preliminarily determined that the door status is unlocked, and further determined whether the door status detection information is reliable and stable based on the duration of the door being detected to be unlocked.

[0058] In some embodiments, it further comprises:

[0059] S51: If the first judgment result is that the RFID reading and writing device reads the target RFID electronic tag information, it is determined that the door remains locked.

[0060] S60: Determine whether the duration is greater than a preset threshold, and obtain a second determination result;

[0061] S70: If the second judgment result is yes, send door loose information.

[0062] If the duration exceeds / is greater than the preset threshold, it can indicate that the door has changed from being initially locked to being loose, and a loose door information is sent to remind the user that he needs to pay attention to the door status and stop the car in a safe section of the road in time to check whether the door is actually locked, so as to avoid the problem of cargo falling due to the door actually being loose.

[0063] In some embodiments, the method further includes: S71: if the second judgment result is no, determining that the door remains locked

[0064] In some embodiments, the target RFID electronic tag is arranged on one side of the vehicle door, and a conductive sheet is arranged on the other side of the vehicle door. When the door is locked, the first electrode contact and the second electrode contact are electrically connected to the conductive sheet, and the chip circuit in the RFID electronic tag is turned on; when the door is loose, the first electrode contact and the second electrode contact are electrically separated from the conductive sheet, and the chip circuit in the RFID electronic tag is not turned on.

[0065] Based on the same inventive concept, an embodiment of the present invention further provides a door state detection system, comprising:

[0066] A verification module, used to control the RFID reading device to start in response to the door lock detection signal. If the target RFID electronic tag information is identified, the door lock detection verification is passed;

[0069] A processing module, configured to obtain a duration of not reading the target RFID electronic tag information if the first judgment result is that the RFID reading and writing device fails to read the target RFID electronic tag information;

[0070] A second judgment module is used to judge whether the duration is greater than a preset threshold and obtain a second judgment result;

[0071] The alarm module is used to send door looseness information if the second judgment result is yes.

[0072] Preferably, the processing module is further configured to determine that the door remains locked if the first judgment result is that the RFID reader / writer reads the target RFID electronic tag information. At this time, there is no need to send information to the user to avoid interfering with the user's safe driving.

[0073] Preferably, the processing module is also used for:

[0074] After the door lock detection verification is passed, the RFID reading and writing device is controlled to be turned off;

[0075] When it is detected that the vehicle enters a bumpy road section, the vehicle speed is greater than a set speed, or the door vibration parameter is greater than a set parameter, the RFID reading and writing device is controlled to turn on;

[0076] The step of determining whether the RFID reader / writer has read the target RFID electronic tag information to obtain a first determination result is performed.
