[0049] Embodiment one

[0050] Figure 1 is a flow chart of an RFID electronic fence-based warehouse entry and exit identification method according to the first embodiment of the present application. The present embodiment can be applied to the warehouse entry and exit identification of objects at warehouse doors or business process side doors. The method can be executed by an RFID electronic fence-based warehouse entry and exit identification device, which can be implemented in the form of hardware and / or software, and can be configured in an electronic device such as an electronic fence, a radio frequency identification device, an access control device, or a computer, etc.

[0051] Figure 2 is a structural schematic diagram of an RFID antenna-embedded electronic fence according to the first embodiment of the present application. As shown in Figure 2 , RFID antenna-embedded electronic fences are arranged on the left and right sides of the warehouse door; the RFID antennas embedded in the electronic fences are inclined at a preset angle. By inclining the RFID antennas at a preset angle, the received signal strength value changes when the object passes through the electronic fence. Then, the object warehouse entry and exit identification is realized through the change of the received signal strength value.

[0052] As shown in Figure 1 , the method comprises:

[0053] Step 110, when the object passes through the warehouse door, the electronic tag on the object is read by the RFID antenna embedded in the electronic fence, and the tag reading time and the corresponding received signal strength value are recorded.

[0054] As shown in Figure 2 When a person or device passes through the electronic fence at the warehouse door, the RFID read-write device can trigger the RFID antenna embedded in the electronic fence to read the electronic tag on the object. The RFID read-write device and the electronic tag can identify object information such as object color, object type, object name, object size, and other attribute information through radio frequency signals. Different electronic tags can be set on different objects, and the electronic tags can have uniqueness. The RFID device can accurately identify different objects by reading the electronic tags.

[0055] The RFID read-write device can monitor the received signal strength value (RSSI) when reading the electronic tag. The RSSI can be obtained by collecting, converting, calculating, and calibrating the radio frequency signal. The determination method of the RSSI value is not limited in the embodiment of the application. In the embodiment of the application, the received signal strength value can be the absolute value of the RSSI value. The strength of the received signal strength value can reflect the distance between the signal point and the receiving point. Therefore, the positioning can be performed by the change of the received signal strength value.

[0056] In the embodiment of the application, the RFID read-write device can record the corresponding tag reading time when monitoring the received signal strength value when reading the electronic tag. That is, the received signal strength value at each time is recorded in real time, so that the in-out warehouse identification can be performed according to the change of the received signal strength value.

[0057] In order to accurately trigger the RFID read-write device to read the electronic tag on the object, an infrared sensor can be arranged on the electronic fence to realize accurate reading and triggering of the electronic tag through the signal of the infrared sensor.

[0058] Optionally, when the object passes through the warehouse door, the electronic tag on the object is read by the RFID antenna embedded in the electronic fence, including: at least one infrared sensor is arranged on the electronic fence, the infrared sensor includes an infrared transmitter and an infrared receiver, the infrared transmitter emits infrared rays; when the object passes through the warehouse door, the infrared receiver receives the infrared rays emitted by the infrared transmitter; the RFID antenna embedded in the electronic fence is triggered to read the electronic tag on the object according to the infrared rays received by the infrared receiver.

[0059] When the object passes through the warehouse door, the infrared rays will be reflected due to the existence of the object, so that the infrared receiver can receive the infrared rays emitted by the infrared emitter and reflected by the object. According to the infrared rays received by the infrared receiver, the RFID antenna in the electric fence can be triggered to read the electronic tag on the object. By triggering the RFID antenna to read the electronic tag on the object through the infrared receiver, the reading accuracy of the RFID read-write device can be improved, and false triggering can be avoided.

[0060] Step 120, according to the change of the received signal strength value in the tag reading time, the warehouse in and out recognition is carried out.

[0061] As shown in Figure 2 , because the RFID antenna in the electric fence is inclined at a preset angle, when the object passes through the electric fence, the received signal strength value of the radio frequency signal will change, and the change of the received signal strength value when entering the warehouse door and the warehouse door will be different. According to the change difference of the received signal strength value, the object in and out of the warehouse can be recognized. The preset angle can be 0-90 degrees, which can be determined according to the thickness of the electric fence.

[0062] According to the different inclination directions of the RFID antenna in the electric fence, the change of the received signal strength value when entering and leaving the warehouse will also be different. For example, as shown in Figure 2 , when the RFID antenna is inclined to the inside of the electric fence (forming "inner eight characters"), when the object enters the warehouse, the change of the received signal strength value may be first attenuated at a first rate and then increased at a second rate, wherein the first rate is greater than the second rate, that is, the received signal strength value first rapidly attenuates and then slowly increases; when the object leaves the warehouse, the change of the received signal strength value may be first attenuated at a third rate and then increased at a fourth rate, wherein the fourth rate is greater than the third rate, that is, the received signal strength value first slowly attenuates and then rapidly increases.

[0063] Or, the RFID antenna is inclined in the opposite direction of Figure 2 , that is, the RFID antenna is inclined to the outside of the electric fence (forming "outer eight characters"), when the object enters the warehouse, the change of the received signal strength value may be first attenuated at a fifth rate and then increased at a sixth rate, wherein the sixth rate is greater than the fifth rate, that is, the received signal strength value first slowly attenuates and then rapidly increases; when the object leaves the warehouse, the change of the received signal strength value may be first attenuated at a seventh rate and then increased at an eighth rate, wherein the seventh rate is greater than the eighth rate, that is, the received signal strength value first rapidly attenuates and then slowly increases.

[0064] Therefore, according to the tilt direction of the RFID antenna embedded in the electronic fence and the change of the received signal strength value, accurate warehouse in-out recognition can be realized; even when multiple objects simultaneously enter or exit the warehouse, the warehouse in-out recognition of each object can be performed according to the corresponding received signal strength value of each electronic tag, thereby ensuring the accuracy of the warehouse in-out recognition.

[0065] Optionally, the warehouse in-out recognition is performed according to the change of the received signal strength value within the tag reading time, including: arranging the real-time acquired received signal strength value according to time based on the tag reading time, and determining a reference time in the arrangement result; calculating a first change rate of the received signal strength value from the tag reading start time to the reference time, and a second change rate of the received signal strength value from the reference time to the tag reading end time; and performing the warehouse in-out recognition according to the first change rate and the second change rate.

[0066] The reference time can be the time corresponding to the minimum value of the received signal strength value, i.e., the minimum value of the absolute value of the RSSI value. The rate of change of the received signal strength value can be calculated in various ways. For example, the change of the received signal strength value from the tag reading start time to the reference time and the change of the received signal strength value from the reference time to the tag reading end time can be fitted respectively by linear regression fitting to obtain two straight lines with different slopes. Figure 3 is a schematic diagram of the change of the received signal strength value when an object passes through an electronic fence according to an embodiment of the present application. As shown in Figure 3 The slope of the straight line can be used as the rate of change of the received signal strength value. Alternatively, the received signal strength value at any multiple time points from the tag reading start time to the reference time can be divided by the time difference to obtain the first change rate. Similarly, the received signal strength value at any multiple time points from the reference time to the tag reading end time can be divided by the time difference to obtain the second change rate.

[0067] The warehouse in-out recognition is performed according to the first change rate and the second change rate. Based on the different tilt directions of the RFID antenna embedded in the electronic fence, different situations of the warehouse in-out recognition can exist, and the specific way of performing the warehouse in-out recognition according to the first change rate and the second change rate can be determined by experiments.

[0068] Optionally, the warehouse in-out recognition is performed according to the first change rate and the second change rate, including: when the RFID antenna is tilted by a preset angle inside the electronic fence, if the first change rate is greater than the second change rate, it is determined that the object enters the warehouse; otherwise, it is determined that the object exits the warehouse; and when the RFID antenna is tilted by a preset angle outside the electronic fence, if the first change rate is less than the second change rate, it is determined that the object enters the warehouse; otherwise, it is determined that the object exits the warehouse.

[0069] In the RFID antenna tilting direction as shown in Figure 2 If the first change rate is greater than the second change rate, it is determined that the object is warehousing; otherwise, it is determined that the object is out of warehouse. That is, in the RFID antenna tilting direction as shown in Figure 2 The change of the received signal strength value as shown in Figure 3 The change of the received signal strength value as shown in

[0070] In the opposite RFID antenna tilting direction as shown in Figure 2 If the first change rate is less than the second change rate, it is determined that the object is warehousing; otherwise, it is determined that the object is out of warehouse. That is, in the opposite RFID antenna tilting direction as shown in Figure 2 The change of the received signal strength value as shown in Figure 3 The change of the received signal strength value as shown in

[0071] The technical scheme of the embodiment sets the electronic fence with the embedded RFID antenna on the left and right sides of the warehouse door; the embedded RFID antenna in the electronic fence is tilted at a preset angle; when the object passes through the warehouse door, the electronic tag on the object is read by the embedded RFID antenna in the electronic fence, and the tag reading time and the corresponding received signal strength value are recorded; the warehousing and out-of-warehouse identification is performed according to the change of the received signal strength value within the tag reading time, which solves the problem of inaccurate identification when multiple objects simultaneously enter and exit the warehouse, and determines the warehousing and out-of-warehouse situation of the object through the change of the received signal strength value when the object passes through the electronic fence, which can improve the warehousing and out-of-warehouse identification accuracy and still ensure the identification accuracy when multiple objects simultaneously enter and exit the warehouse.

[0072] Embodiment two

[0073] Figure 4 It is a flowchart of a warehousing and out-of-warehouse identification method based on an RFID electronic fence according to the embodiment two of the present application. The embodiment is a further addition to the above technical scheme, and the technical scheme in the embodiment can be combined with each optional scheme in one or more of the above embodiments.

[0074] The electronic fence with the embedded RFID antenna is set on the left and right sides of the warehouse door; the embedded RFID antenna in the electronic fence is tilted at a preset angle. At least one infrared sensor is arranged on the electronic fence, the infrared sensor includes an infrared emitter and an infrared receiver, and the infrared emitter emits infrared rays.

[0075] As shown in Figure 4 The method includes:

[0076] Step 410, when the object passes through the warehouse door, the infrared receiver receives the infrared rays emitted by the infrared emitter.

[0077] Step 420, triggering the RFID antenna embedded in the electronic fence according to the infrared received by the infrared receiver to read the electronic tag on the object.

[0078] Step 430, recording the tag reading time and the corresponding received signal strength value.

[0079] Step 440, according to the tag reading time, sorting the real-time acquired received signal strength value by time, and determining the reference time in the sorting result.

[0080] Step 450, calculating the first change rate of the received signal strength value from the tag reading start time to the reference time, and the second change rate of the received signal strength value from the reference time to the tag reading end time.

[0081] Step 460, according to the first change rate and the second change rate, identifying the warehouse in and out.

[0082] Optionally, according to the first change rate and the second change rate, identifying the warehouse in and out, including: when the RFID antenna is tilted at a preset angle inside the electronic fence, if the first change rate is greater than the second change rate, it is determined that the object is warehoused; otherwise, it is determined that the object is warehoused; when the RFID antenna is tilted at a preset angle outside the electronic fence, if the first change rate is less than the second change rate, it is determined that the object is warehoused; otherwise, it is determined that the object is warehoused.

[0083] On the basis of the above embodiment, the method further comprises: determining the flow result of the object in each business process according to the identification result of the object in and out of the warehouse door of each business process and the corresponding tag reading time; and determining whether the business execution process of the object is correct according to the business process and the flow result.

[0084] Through the above-mentioned manner, the in and out of the warehouse of each object can be determined, as well as the time when the in and out of the warehouse occurs, so that according to the in and out of the warehouse of each object and the time when the in and out of the warehouse occurs, the flow result of the object in each business process can be determined. For example, object A is warehoused at 3:10 pm in business process 1, object A is warehoused at 3:12 pm in business process 2, object A is warehoused at 4:00 pm in business process 2, and object A is warehoused at 4:03 pm in business process 3. In the maintenance of the machine room of the financial institution, for different maintenance business processes, the flow order of a specific object can be specified. When the flow result of the object in the business process is consistent with the business process, it can be determined whether the business execution process of the object is correct; otherwise, an object flow abnormality alarm can be given. Through the identification of the in and out of the warehouse of the object, the business execution process of the object can be tested, which can reduce the manual monitoring of the business execution, and ensure the correctness and efficiency of the business execution.

[0085] On the basis of the above-mentioned embodiments, optionally, the method further comprises: when the object is a human body, determining whether the current human body storage meets the preset user permission according to the storage and withdrawal identification result of the human body at the plurality of business process side warehouse doors; when the current human body storage does not meet the preset user permission, performing human body storage abnormality alarm, and determining to eliminate the human body storage abnormality alarm when the current human body withdraws according to the storage and withdrawal identification result.

[0086] When the object is a human body, the storage and withdrawal state of the human body at each business process side warehouse door and the occurrence time can be determined according to the foregoing manner. In the maintenance of the machine room of the financial institution, there may be some information security scenarios, and therefore the access permission of the user may be different for different business processes. Different preset user permissions can be set for different users. The storage and withdrawal state of the user at each business process side warehouse door is compared with the corresponding preset user permission to determine whether the user has access permission at the current business process side warehouse door, and if not, human body storage abnormality alarm is performed, and the human body storage abnormality alarm is eliminated when the current human body withdraws according to the storage and withdrawal identification result.

[0087] By determining the access permission of the user at each warehouse door according to the object storage and withdrawal identification result, the access security of each warehouse such as the machine room can be improved.

[0088] On the basis of the above-mentioned embodiments, optionally, the method further comprises: receiving the change of the signal strength value within the tag reading time, and further comprising: determining the storage and withdrawal quantity of the same type of object according to the storage and withdrawal identification result and the electronic tag; updating the warehouse material list according to the storage and withdrawal quantity, and prompting material procurement according to the warehouse material list.

[0089] The type of the object can be identified by the electronic tag, and the quantity change of the same type of object in the warehouse can be determined by counting the storage and withdrawal quantity of the same type of object, so as to update the warehouse material list. When the quantity of the object in the warehouse material list is less than the preset lower limit, the material procurement of the object can be prompted. The material procurement prompt can ensure that the equipment and parts in the machine room are sufficient to meet the normal maintenance requirements.

[0090] The technical scheme of the embodiment of the application is that: the electronic fence with the embedded RFID antenna is arranged on the left and right sides of the warehouse door; the embedded RFID antenna in the electronic fence is inclined at a preset angle; when the object passes through the warehouse door, the infrared receiver receives the infrared rays emitted by the infrared emitter; the embedded RFID antenna in the electronic fence is triggered to read the electronic tag on the object according to the infrared rays received by the infrared receiver; the tag reading time and the corresponding received signal strength value are recorded; the real-time acquired received signal strength value is sorted according to time according to the tag reading time, and the reference time is determined in the sorting result; the first change rate of the received signal strength value from the tag reading start time to the reference time is calculated, and the second change rate of the received signal strength value from the reference time to the tag reading end time is calculated; the warehouse in-out identification is performed according to the first change rate and the second change rate, thereby solving the problem of inaccurate identification when multiple objects simultaneously enter and exit the warehouse, determining the warehouse in-out situation of the object through the change of the received signal strength value when the object passes through the electronic fence, and improving the warehouse in-out identification accuracy, and ensuring the identification accuracy when multiple objects simultaneously enter and exit the warehouse; on the basis of the warehouse in-out identification, the object flow process judgment, the user access permission judgment and the material purchase prompt can be performed, so that on the basis of the accurate equipment in-out machine room and warehouse record, the artificial maintenance cost is reduced, and the warehousing intelligent level is improved.
