[0034] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

[0035] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0037] In this application, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.
[0038] Please refer to the following first. Figure 1 , Figure 1 This is a flowchart illustrating an exemplary embodiment of the present application, showing a synesthetic method. For example... Figure 1As shown, the method includes at least S110 to S130, which are described in detail below:
[0039] S110: During the first uplink time slot, a sensing signal is sent from the first array of the first node to the second node, so that the second array of the second node receives the sensing signal.
[0040] In this embodiment, the first node includes a first array and a second array. The first array can be switched to transmit or receive sensing signals as needed; the second array is for receiving sensing signals. Similarly, the second node also includes a first array and a second array, and their functions are the same as those of the first array and second array in the first node, which will not be repeated here.
[0041] In this embodiment, the uplink time slot and downlink time slot are relative concepts, used only to distinguish whether the first node or the second node is the end that transmits the sensing signal. As described in this embodiment, in the first uplink time slot, the first array of the first node transmits the sensing signal; if in the downlink time slot, it is the first array of the second node that transmits the sensing signal.
[0042] During the first uplink time slot, the first array of the first node sends a sensing signal, and the second array of the second node receives the sensing signal. At the same time, the second array of the first node also receives the sensing signal.
[0043] S120: In the second uplink time slot, receive the sensing signal through the second array of the first node; wherein, the second uplink time slot includes the first uplink time slot and the first protection time slot, and the first protection time slot is a preset time period after the first uplink time slot.
[0044] A first protection time slot is set after the first uplink time slot to form the second uplink time slot. It is worth noting that during the protection time slot, the first array of the first node no longer transmits sensing signals, while the array with receiving capabilities continues to receive sensing signals.
[0045] The length of the first protection time slot, i.e. the length of the preset time period, is adjusted according to the actual situation. This embodiment does not limit its specific duration.
[0046] S130: During the second downlink time slot, receive the sensing signal sent by the second node through the second array of the first node.
[0047] Within the second downlink time slot, the first array of the second node transmits a sensing signal, and the second array of the second node and the second array of the first node receive the sensing signal. The second arrays of both the first and second nodes are arrays that receive sensing signals, regardless of whether they are in the uplink or downlink time slot.
[0048] In this embodiment, the structure of a designated node in the sensing network is modified. A first array with the function of sending / receiving sensing signals and a second array with the function of receiving sensing signals are set in the designated node. This allows the first node to send and receive sensing signals simultaneously in the uplink and downlink time slots. In the second downlink time slot, the first node that sends sensing signals is switched to the second node, and the second array of the first node receives the sensing signals sent by the second node.
[0049] In addition, a protection time slot is added after the first uplink time slot so that the time for the first node to receive the sensing signal is longer than the time to send the sensing signal. This ensures the time required for the uplink / downlink time slot switching process and ensures that the first node fully receives the sensing signal it sent, thus avoiding any impact on the signal transmission of the next time slot.
[0050] Please see Figure 2 , Figure 2 Based on Figure 1 A flowchart of another synesthesia method proposed in the illustrated embodiment. Based on Figure 1 Based on the synesthesia method shown, Figure 2 The method shown also includes at least S210 to S220, which are described in detail below:
[0051] S210: Receive switching command, which is used to indicate the switching of the functional status of the first array of the first node.
[0052] In this embodiment, the first array of the first node has the function of transmitting and receiving sensing signals, such as... Figure 3 As shown, Figure 3 This is a schematic diagram of the structure of a node in a sensing network. In this embodiment, the network node can represent the first node. When the first array of the first node is connected to the transmitting radio frequency link, the first array has the function of transmitting sensing signals; when the first array is connected to the receiving radio frequency link, the first array receives sensing signals; when the first array is not connected to either the transmitting or receiving radio frequency link, the first array has no functional state, and at this time, the first node only has the functional state of receiving sensing signals, that is, its second array receives sensing signals.
[0053] S220: According to the switching instruction, the first array of the first node is switched from the state of transmitting sensing signals to the state of receiving sensing signals.
[0054] For example, in the first uplink time slot, the first array of the first node is connected to the transmit RF link and transmits a sensing signal, and the second array of the first node and the second array of the second node receive the sensing signal; in the second downlink time slot, if the first node receives a switching signal, it switches the first array of the first node to be connected to the receive RF link, so that the first array of the first node receives the sensing signal. It is worth noting that in this case, both the first array and the second array of the first node can receive the sensing signal.
[0055] The switching instruction in this embodiment can also be used to instruct the first array of the first node to switch from the state of receiving sensing signals to the state of transmitting sensing signals. For example, when the first node receives the switching instruction, it detects the functional state of its first array. If the first array of the first node is in the state of transmitting sensing signals, it switches it to the state of receiving sensing signals; if the first array of the first node is in the state of receiving sensing signals, it switches it to the state of transmitting sensing signals.
[0056] Furthermore, the functional status of the first array of the first node can be detected by detecting the link connected to the first array at the current moment. If the first array is detected to be connected to the transmitting radio frequency link, it indicates that the first array is in the functional status of transmitting sensing signals at the current moment; if the first array is detected to be connected to the receiving radio frequency link, it indicates that the first array is in the functional status of receiving sensing signals at the current moment.
[0057] This embodiment further illustrates how to switch the functional state of the first array of the first node. If a switching command is received, the functional state of the first array of the first node is switched to meet the functional requirements of the first node in a timely manner. According to the switching command, the first array of the first node is switched from the state of transmitting sensing signals to the state of receiving sensing signals, so that both the first array and the second array of the first node are in the functional state of receiving sensing signals, thereby enhancing the first node's ability to receive sensing signals.
[0058] In another embodiment, the corresponding time slots can also be arranged in a preset order, as shown in Table 1, which is an example of a period configuration table:
[0059] Serial Number Time slot 1 Time slot 2 Time slot 3 Time slot 4 Time slot 5 1 D D S U U 2 D S U U U 3 D D D S U 4 … … … … …
[0060] Table 1
[0061] Where D represents downlink time slot; U represents downlink time slot; and S represents flexible time slot, which can be adjusted to uplink or downlink time slot according to actual conditions.
[0062] For example, a periodic configuration parameter with sequence number 1 is selected, where time slots 1 and 2 are downlink time slots, time slot 3 is a flexible time slot, and time slots 4 and 5 are uplink time slots. Within the downlink time slots, the first array of the second node transmits a sensing signal, and the second array of the second node and the second array of the first node receive the sensing signal. In a preferred embodiment, to enhance the first node's ability to receive sensing signals, the first array of the first node can also receive sensing signals. Within the uplink time slots, the first array of the first node transmits the sensing signal, and the second array of the first node and the second array of the second node receive the sensing signal. In a preferred embodiment, to enhance the second node's ability to receive sensing signals, the first array of the second node can also receive sensing signals.
[0063] In another example, the central node sends the above-mentioned periodic configuration table to the first node and the second node. After the first node and the second node have configured the complete timeslot parameters, they feed back their configuration results to the central node. If the configuration is successful, they feed back ack information; if the configuration fails, they feed back nack information. If the central node receives the ack information from the first and second nodes, the update is successful; otherwise, it fails and the original configuration is used.
[0064] The first and second nodes transmit / receive sensing signals according to the time slot parameters of the relevant sequence numbers in Table 1. The first node transmits sensing signals through the first array during the uplink time slot and simultaneously activates the second array to receive sensing signals. It remains silent during the subsequent preset protection time slot. The second node continuously activates the second array to receive sensing signals, and optionally activates the first array of the second node to receive sensing signals until the preset time of this cycle is reached.
[0065] The second node transmits a sensing signal through the first array during the downlink time slot, and simultaneously activates the second array to receive the sensing signal. It remains silent during the subsequent preset protection time slot. The first node continuously activates the second array to receive the sensing signal, and optionally activates the first array to receive the sensing signal until the preset time for this cycle is reached.
[0066] The sensing configuration information in this embodiment is flexible and versatile. The uplink / downlink time slot ratio in the periodic configuration table can be dynamically adjusted according to actual needs, making it widely adaptable to diverse scenarios and business requirements.
[0067] Please see Figure 4 , Figure 4 Based on Figure 1 A flowchart of another synesthetic method proposed in the illustrated embodiment. This method... Figure 1 Based on the synesthesia method shown, it also includes at least S410 and / or S420, which are described in detail below:
[0068] S410: Update the first uplink time slot to obtain the updated first uplink time slot, and send the sensing signal to the second node through the first array of the first node within the updated first uplink time slot.
[0069] S420: Update the second uplink time slot to obtain the updated second uplink time slot, and receive the sensing signal through the second array of the first node within the updated second uplink time slot.
[0070] In this embodiment, the updating of the first and second uplink time slots can be performed actively or passively by the first node. For example, the first node updates the relevant time slots only upon receiving an instruction to update them. During active updating, the first node can periodically update the relevant time slots according to a preset period, or it can update them in real time based on other parameters or actual conditions. The update process includes, but is not limited to, the length of the corresponding time slot and the order of the uplink / downlink time slots. Additionally, the second downlink time slot can also be updated, and within the updated second downlink time slot, the first node receives the sensing signal sent by the second node through its second array.
[0071] This embodiment illustrates that updates can be made to the relevant uplink and / or downlink time slots to adjust the time slots for transmitting or receiving sensing signals from the corresponding array, resulting in a variety of different time slot combinations to suit different services and scenarios. This makes the sensing method of this embodiment widely applicable to diverse scenarios and service requirements.
[0072] Please see Figure 5 , Figure 5 Based on Figure 4 A flowchart of another synesthetic method proposed in the illustrated embodiment. This method, in... Figure 4 The S410 shown includes at least S510 to S520; and the S420 includes at least S530 to S540, which will be described in detail below:
[0073] S510: Detect whether a first update request has been received from a specified node; wherein the specified node includes at least one of the first node and the second node.
[0074] This embodiment further illustrates the passive update process, that is, upon receiving a first update request sent by the first node and / or the second node, the corresponding update operation is performed.
[0075] S520: If the first update request sent by the specified node is received, the first uplink timeslot is updated to obtain the updated first uplink timeslot.
[0076] The first update request is a request to update the first uplink time slot. If the first update request is received from the first node and / or the second node, the first uplink time slot is updated, and within the updated first uplink time slot, a sensing signal is sent from the first array of the first node to the second node, so that the second array of the second node receives the sensing signal.
[0077] S530: Detect whether a second update request has been received from a specified node; wherein the specified node includes at least one of the first node and the second node.
[0078] The second update request is a request to update the second uplink time slot.
[0079] S540: If a second update request is received from a specified node, the second uplink timeslot is updated to obtain the updated second uplink timeslot.
[0080] If a second update request is received from the first node and / or the second node, the second uplink time slot is updated, and the sensing signal is received through the second array of the first node within the updated second uplink time slot.
[0081] This embodiment further illustrates how to passively update the first uplink time slot and the second uplink time slot. By detecting the receipt of a first update request, the first uplink time slot is updated; by detecting the receipt of a second update request, the second uplink time slot is updated, thereby timely and adaptively updating the corresponding time slots.
[0082] Please see Figure 6 , Figure 6 This is a schematic diagram of an implementation environment involved in the application. It includes server 600, first node 610, and second node 620. Server 600 is located within first node 610 and acts as the execution endpoint. Figure 1 , Figure 2 , Figure 4 , Figure 5 The induction method in any of the embodiments shown.
[0083] For example, during the first uplink time slot, server 600 sends a sensing signal to second node 620 through the first array of first node 610, so that the second array of second node 620 receives the sensing signal. In a preferred embodiment, the first array of second node 620 can also receive the sensing signal to enhance the ability of second node 620 to receive the sensing signal.
[0084] In the second uplink time slot, server 600 receives a sensing signal through the second array of first node 610; wherein, the second uplink time slot includes a first uplink time slot and a first protection time slot, the first protection time slot being a preset time period following the first uplink time slot; and in the second downlink time slot, server 600 receives a sensing signal sent by second node 620 through the second array of first node 610.
[0085] Server 600 can be a standalone physical server, or a server cluster or distributed system consisting of multiple physical servers. Multiple servers can form a blockchain, and the server is a node on the blockchain. Server 600 can also be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms. This document does not impose any restrictions on this.
[0086] In another exemplary embodiment of this application, the second node is used as the execution end to perform the synesthetic method; please refer to [link to specific examples]. Figure 7 , Figure 7 This is a flowchart illustrating a sensing method according to another exemplary embodiment of this application. The method includes at least steps S710 to S730, which are described in detail below:
[0087] S710: During the first downlink time slot, a sensing signal is sent from the first array of the second node to the first node so that the second array of the first node can receive the sensing signal.
[0088] The first array of the second node is the same as the first array of the first node, and has the function of transmitting and receiving sensing signals. In the first downlink time slot, the first array of the second node transmits the sensing signal, and its second array receives the sensing signal. At the same time, the second array of the first node also receives the sensing signal.
[0089] S720: In the second downlink time slot, receive the sensing signal through the second array of the second node; wherein, the second downlink time slot includes the first downlink time slot and the second protection time slot, and the second protection time slot is a preset time period after the first downlink time slot.
[0090] The second protection time slot is set after the first downlink time slot. In this embodiment, the length of the second protection time slot can be the same as or different from that of the first protection time slot. That is, the length of the preset time period can be the same, or it can be set according to the actual situation.
[0091] S730: During the first uplink time slot, it receives the sensing signal sent by the first node through the second array of the second node.
[0092] During the first uplink time slot, the first array of the first node transmits a sensing signal, and the second array of the first node and the second array of the second node receive the sensing signal. In a preferred embodiment, the first array of the second node can be switched to a function state of receiving sensing signals to enhance the ability of the second node to receive sensing signals.
[0093] In this embodiment, in the sensing network, the second node simultaneously transmits and receives sensing signals in the uplink / downlink time slots. In the first uplink time slot, the second node transmitting the sensing signal is switched to the first node, and the second array of the second node receives the sensing signal transmitted by the first node.
[0094] In addition, a protection time slot is added after the first downlink time slot so that the time for the second node to receive the sensing signal is longer than the time to send the sensing signal. This ensures the time required for the uplink / downlink time slot switching process and ensures that the second node fully receives the sensing signal it sends, thus avoiding any impact on the signal transmission in the next time slot.
[0095] Please see Figure 8 , Figure 8 Based on Figure 7 A flowchart of another induction method proposed in the illustrated embodiment. This method also includes steps S810 to S820, which are described in detail below:
[0096] S810: Receives a switching command, which is used to indicate the switching of the functional status of the first array of the second node.
[0097] The structural diagram of the second node in the sensor network in this embodiment is also as follows. Figure 3 As shown, the second node and the first node have the same structure. Both nodes include a first array that has the function of sending and receiving sensing signals, and a second array that has the function of receiving sensing signals.
[0098] Specifically, when the first array of the second node is connected to the transmitting radio frequency link, the first array is in the functional state of transmitting sensing signals; when the first array is connected to the receiving radio frequency link, the first array is in the functional state of receiving sensing signals; when the first array is not connected to the transmitting radio frequency link or the receiving radio frequency link, the first array does not have a functional state. At this time, the second node only has the functional state of receiving sensing signals, that is, its second array receives sensing signals.
[0099] S820: According to the switching command, the first array of the second node is switched from the state of transmitting sensing signals to the state of receiving sensing signals.
[0100] For example, the first array of the second node is currently connected to the transmitting radio frequency link, that is, the first array is in the functional state of transmitting sensing signals. If a switching command is received, the first array is switched to be connected to the receiving radio frequency link, that is, it is switched from the state of transmitting sensing signals to the state of receiving sensing signals. At this time, both the first array and the second array of the second node are in the functional state of receiving sensing signals.
[0101] This embodiment further illustrates how to switch the functional state of the first array of the second node. If a switching command is received, the functional state of the first array of the second node is switched to meet the functional requirements of the second node in a timely manner. According to the switching command, the first array of the second node is switched from the state of transmitting sensing signals to the state of receiving sensing signals, so that both the first array and the second array of the second node are in the functional state of receiving sensing signals, thereby enhancing the ability of the second node to receive sensing signals.
[0102] In another embodiment, based on Figure 8 The inductive method in the illustrated embodiment further includes steps (a) and / or (b), which will be described in detail below:
[0103] Step (a): Update the first downlink time slot to obtain the updated first downlink time slot, and send the sensing signal to the first node through the first array of the second node within the updated first downlink time slot.
[0104] Step (b): Update the second downlink time slot to obtain the updated second downlink time slot, and receive the sensing signal through the second array of the second node within the updated second downlink time slot.
[0105] In this embodiment, the updating of the first and second downlink time slots can be performed by the second node actively or passively. For example, the second node only updates the relevant time slots upon receiving an instruction to update them. During active updating, the second node can periodically update the relevant time slots according to a preset period, or it can update them in real time based on other parameters or actual conditions. The update process includes, but is not limited to, the length of the corresponding time slots and the order of uplink / downlink time slots. Additionally, the first uplink time slot can also be updated, and within the updated first uplink time slot, the second node receives the sensing signal sent by the first node through its second array.
[0106] This embodiment illustrates that updates can be made to the relevant uplink and / or downlink time slots to adjust the time slots for transmitting or receiving sensing signals from the corresponding array, resulting in a variety of different time slot combinations to suit different services and scenarios. This makes the sensing method of this embodiment widely applicable to diverse scenarios and service requirements.
[0107] In another embodiment, step (a) further includes steps (a') and (a”), and step (b) further includes steps (b') and (b”), which will be described in detail below:
[0108] Step (a'): Detect whether a third update request has been received from a specified node; wherein the specified node includes at least one of the first node and the second node.
[0109] The third update request is a request to update the first downlink time slot.
[0110] Step (a”): If a third update request is received from the specified node, the first downlink time slot is updated to obtain the updated first downlink time slot.
[0111] If a third update request is received from the first node and / or the second node, the first downlink time slot is updated, and within the updated first downlink time slot, a sensing signal is sent from the first array of the second node to the first node, so that the second array of the first node receives the sensing signal.
[0112] Step (b'): Detect whether a fourth update request has been received from a specified node; wherein the specified node includes at least one of the first node and the second node.
[0113] The fourth update request is a request to update the second downlink time slot.
[0114] Step (b”): If a fourth update request is received from the specified node, the second downlink time slot is updated to obtain the updated second downlink time slot.
[0115] If a fourth update request is received from the first node and / or the second node, the second downlink time slot is updated, and the sensing signal is received through the second array of the second node within the updated second downlink time slot.
[0116] This embodiment is a passive update process, that is, when a third update request is received from the first node and / or the second node, and / or a fourth update request is received from the first node and / or the second node, the corresponding update operation is performed in a timely manner.

In a preferred embodiment, the first array of first node 910 can also receive the sensing signal to enhance the ability of first node 910 to receive the sensing signal.
