[0051] The example embodiments will be described in detail herein with reference to the attached drawings. The following description is made with reference to the accompanying drawings in which like reference numerals represent like elements or similar elements, unless the context dictates otherwise. The following description of example embodiments is not representative of all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0052] It can be understood that the terms "first", "second", and the like in the present disclosure are used to describe various information, but the information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other, and do not indicate a particular order or importance.

[0053] It can be further understood that, although the operations are described in a particular order in the examples of the present disclosure, the order of the operations should not be construed as requiring the operations to be performed in the particular order, or in serial, or that all of the operations are necessary to achieve desirable results. In certain circumstances, multitasking and parallel processing can be advantageous.

[0054] It should be noted that all actions of acquiring signals, information or data in the present disclosure are performed in compliance with the corresponding data protection regulations and policies of the country where the device is located, and with the authorization of the owner of the corresponding device.

[0055] Figure 1 is a flowchart of still another system control right management method according to an example embodiment, as Figure 1As shown, the method is applied to a first node in a system, the system comprising a plurality of levels of nodes, the first node being any one of the plurality of levels of nodes, and the method comprising the steps of:

[0056] In step S101, in the case that the first node is not a node having a system control right, first control right application information is sent to all other nodes in the system, the all other nodes being all nodes in the system except the first node, the first control right application information being used to apply for transferring the system control right to the first node.

[0057] Exemplarily, a modern urban rail transit real-time monitoring system generally comprises a plurality of levels, the plurality of levels corresponding to a plurality of nodes, which can be referred to as a plurality of levels of nodes, and the first node can be any one of the plurality of levels of nodes. When the node having the system control right is not the first node, if the first node wants to have the control right of the system, the first node needs to send first control right application information to all other nodes in the system to apply for the control right of the system. For example, when the system adopts three-level control of a center level, a station level and an on-site level, when the system control right is not in the center level node but the center level node wants to apply for the system control right, the center level node sends control right application information to the other two level nodes of the system, i.e., the station level node and the on-site level node, to apply for the control right of the system.

[0058] In step S102, in the case that the number of the other nodes replying to the agreement message is greater than or equal to a set number, it is determined that the first node is changed to a node having the system control right.

[0059] Exemplarily, when the number of the other nodes of the system replying to the agreement is greater than or equal to the preset number of nodes of the system control right, the first node is changed to a node having the system control right. For example, when the center level node of the system applies for the system control right, the station level node and the on-site level node of the system both reply to the agreement, and the center level node obtains the control right of the system. When the system has more nodes than the three level nodes, the preset number of nodes can be set according to the actual total number of nodes, for example, all nodes except the first node can still be set to agree, or at least two-thirds of the nodes except the first node can also be set to agree, and the first node can obtain the control right of the system.

[0060] In step S103, a right taking back instruction is sent to a second node in the system, the second node being a node having the system control right before the change, and the right taking back instruction being used to instruct the second node to transfer the system control right to the first node.

[0061] Exemplarily, when the system first level obtains the reply of the consent application, the first node sends the authority retrieval instruction to the second node in the system which has the control authority of the system, and the second node transfers the control authority to the first node; for example, when the authority of the system is at the station level node, the central level node applies for the control authority of the system, and when the central level node obtains the reply of the consent application, the station level node of the system transfers the application authority of the system to the central level node of the system.

[0062] Figure 2 is a flow chart of another system control authority management method according to an exemplary embodiment, as shown in Figure 2 Before step S101, the method further comprises the following steps:

[0063] In step S104, the maximum node identifier in the node identifiers of the nodes at all levels in the system is determined.

[0064] In step S105, when the node identifier of the first node is the maximum node identifier, it is determined that the first node is the node having the control authority of the system.

[0065] In step S106, when the node identifier of the first node is not the maximum node identifier, it is determined that the first node is not the node having the control authority of the system.

[0066] Exemplarily, each node at all levels can represent whether it is the node having the control authority of the system through the node identifier, for example, the node identifier can be represented as Node_ID, and the Node_ID can be a node number for example, and the Node_ID having the control authority of the system in the system is the maximum, thus it can be determined which node in the nodes at all levels in the system has the maximum node identifier, and the node having the maximum node identifier is the node having the control authority of the system, and if the control authority of the system is transferred, the Node_ID of the new node having the control authority of the system can be set as the maximum Node_ID in the nodes.

[0067] Therefore, when the node identifier of the first node is the maximum node identifier in the node identifiers of the nodes at all levels in the system, it is determined that the first node in the system is the node having the control authority of the system, and at this time, the first node can directly initiate the control of the BAS (Building Automation System, environmental and equipment monitoring system) system; when the node identifier of the first node is not the maximum node identifier in the system, it is determined that the first node in the system is not the node having the control authority of the system, and at this time, the first node needs to apply for the transfer of the control authority of the system first, and after the consent of other nodes, the first node can have the control authority of the system.

[0068] Figure 3is a flowchart of another system control right management method according to an exemplary embodiment, as Figure 3 As shown in FIG. 10, the step S102 includes the following steps.

[0069] In step S1021, if the number of the other nodes replying the consent message is greater than or equal to the set number within the first time length, it is determined that the first node becomes the node having the system control right.

[0070] In step S1022, the node identifier of the first node is modified to the largest node identifier among the nodes in the system.

[0071] In step S1023, a first victory message is sent to all the other nodes, the first victory message carrying the modified node identifier of the first node, the first victory message being used to announce the first node as the updated node having the system control right.

[0072] Exemplarily, when the first node sends the first system control right application, a timer can be started, the starting time of the timer being the time when the first node sends the first system control right application. If the number of the other nodes replying the consent message is greater than or equal to the set number within the preset first time length, the first node successfully applies for the system control right, the node identifier of the first node is modified to the largest node identifier in the system, and then the first node sends a first victory message to the other nodes in the system, the message including the modified node identifier (the largest node identifier) of the first node, so as to convey the modified node identifier of the first node to the other nodes in the system, so as to inform the other nodes that the first node becomes the node currently having the system control right of the system. For example, in a system including a center node, a station node and a local node, the set number can be set to 2. When the station node without the system control right sends the system control right application to the center node and the local node, if the consent messages replying from the center node and the local node are received within the preset first time length, the station node successfully applies for the system control right of the system, the node identifier of the station node is modified to the largest node identifier in the system, and then a success application message is sent to the other nodes, the success application message including the modified node identifier of the station node, so as to inform the other nodes that the station node currently has the system control right.

[0073] Optionally, the system control right management method can further include:

[0074] If the number of the other nodes replying the consent message is less than the set number, it is determined that the first node fails to apply for the system control right.

[0075] For example, if the first node receives fewer than a preset number of reply consent messages within a preset first duration, the first node's application for system control authority fails. Furthermore, if the number of other nodes to which the first node receives reply consent messages is greater than or equal to a preset number, but the first duration has expired when the first node receives consent messages from one or more of these nodes, the first node's application for system control authority is also determined to have failed.

[0076] Optionally, the system control right management method may further include:

[0077] Receive a second victory message sent by a third node in the system, where the second victory message carries a modified node identifier of the third node. The third node is any node in the system that does not have system control authority. The second victory message is used to declare the third node as an updated node with system control authority.

[0078] Exemplarily, when the first node has not applied for system control authority, or the first node has failed to apply for system control authority, the first node may wait for other nodes to send a victory message for notifying the transfer of system control authority. For example, when a second victory message is received from a third node in the system that does not have the system control authority, the modified node identifier of the third node carried in the second victory message is the largest node identifier in the system, and it can be known that the third node has successfully applied for system control authority.

[0079] When the first node is a node with system control authority, it can also receive control request information initiated by other nodes. Figure 4 is a flow chart showing another method for managing system control rights according to an exemplary embodiment. Figure 4 As shown, the system control right management method may further include the following steps:

[0080] In step S107, when the first node is a node with system control authority, a second control right application information sent by a fourth node in the system is received. The fourth node is any node in the system that does not have system control authority. The second control right application information is used to apply to transfer the system control authority to the fourth node.

[0081] In step S108, an approval message or a rejection message is replied to the fourth node.

[0082] Exemplarily, when the first node in the system has the system control right, a fourth node in the system which does not have the system control right sends second control right application information to other nodes in the system (including the first node having the system control right and other nodes except the first node and the fourth node), and the first node receives the second control right application information and replies an approval message or a rejection message to the fourth node. For example, in a system composed of a center-level node, a station-level node and an on-site node, when the center-level node has the system control right, the center-level node can receive control right application information sent by the on-site node or the station-level node in the system, and the center-level node receives the control right application information and replies an approval message or a rejection message to the on-site node or the station-level node. The processing method of the on-site node or the station-level node after receiving the approval message or the rejection message can refer to the above Figures 1 to 4 The content described in the embodiments will not be repeated.

[0083] Figure 5 is a flowchart of another system control right management method according to an exemplary embodiment, as shown in Figure 5 The system control right management method further includes the following steps:

[0084] In step S109, when the first node is not the node having the system control right, third control right application information sent by a fifth node in the system is received, the fifth node being any node in the system which does not have the system control right, and the third control right application information being used to apply for transferring the system control right to the fifth node.

[0085] In step S110, an approval message or a rejection message is replied to the fifth node.

[0086] Exemplarily, when the first node in the system does not have the system control right, the first node can also receive third control right application information sent by the fifth node in the system which does not have the system control right, and the first node receives the third control right application information and can reply an approval message or a rejection message to the fifth node. For example, in a system composed of a center-level node, a station-level node and an on-site node, when the on-site node does not have the system control right and the center-level node has the system control right, the station-level node can send control right application information to the center-level node and the on-site node. The on-site node also needs to reply an approval message or a rejection message to the station-level node although it does not have the system control right. The processing method of the station-level node after receiving the approval message or the rejection message can refer to the above Figures 1 to 4 The content described in the embodiments will not be repeated.

[0087] Figure 6 is a flow chart of still another system control right management method according to an example embodiment, as shown in Figure 6 The method further includes the following steps:

[0088] In step S111, after sending the first control right application information to all other nodes in the system, the first node starts timing.

[0089] In step S112, if no agreement message or rejection message is received from the sixth node within the first time period after the timing is started, it is considered that the sixth node agrees. The sixth node is any node in the system.

[0090] For example, after the first node sends the first control right application information to all other nodes in the system, the first node starts timing. If no agreement message or rejection message is received from the sixth node within the first time period after the timing is started, it is considered that the sixth node agrees. The sixth node is any node in the system other than the first node. That is, if any node in the other nodes does not reply to the first node within the first time period, it is considered that the node agrees. For example, after a local node in the system receives the system control right application information sent by a central node in the system, if the local node does not reply to the central node within the first time period, it is considered that the local node agrees with the system control right application information sent by the central node.

[0091] Optionally, in various embodiments of the present disclosure, the system can be a building automation system (BAS), and the multiple levels of nodes include a central node, a station node, and a local node.

[0092] For example, the system has three or more levels, and the system is a building automation system (BAS). When the system has three levels including a central level, a station level, and a local level, the multiple levels of nodes include a central node, a station node, and a local node.

[0093] Figure 7 is a block diagram of a system control right management device according to an example embodiment, applied to a first node in a system, the system including multiple levels of nodes, the first node being any level of node in the multiple levels of nodes, as shown in Figure 7 The system control right management device 700 includes a sending module 701 and a determining module 702.

[0097] Optionally, the system control authority management apparatus 700 further includes a node identifying module and an authority determining module.

[0098] The node identifying module is configured to, before the sending module 701 sends the control authority application information to all other nodes in the system in a case where the first node is not a node that has the system control authority, determine a maximum node identifier among node identifiers of nodes at all levels in the system.

[0099] The authority determining module is configured to, in a case where the node identifier of the first node is the maximum node identifier, determine that the first node is a node that has the system control authority.

[0100] The authority determining module is further configured to, in a case where the node identifier of the first node is not the maximum node identifier, determine that the first node is not a node that has the system control authority.

[0101] Optionally, the determining module 702 is configured to:

[0104] Send a first victory message to the all other nodes, the first victory message carrying the modified node identifier of the first node, the first victory message being used to announce that the first node is an updated node that has the system control authority.

[0105] Optionally, the authority determining module is further configured to:

[0106] determining that the first node fails to apply for the system control right in a case where a number of other nodes replying the consent message is less than a set number.

[0107] Optionally, the system control right management apparatus 700 further comprises a receiving module configured to:

[0108] receive a second victory message sent by a third node in the system, the third node being any node in the system without the system control right, the second victory message carrying a modified node identity of the third node, and the second victory message being used to announce that the third node is an updated node with the system control right.

[0109] Optionally, the receiving module is further configured to:

[0111] the sending module 701 is configured to reply a consent message or a rejection message to the fourth node.

[0112] Optionally, the receiving module is further configured to, in a case where the first node is not a node with the system control right, receive third control right application information sent by a fifth node in the system, the fifth node being any node in the system without the system control right, and the third control right application information being used to apply for transferring the system control right to the fifth node.

[0117] Through the technical solution, when any node without control authority needs to control the BAS system, the node needs to send control authority application information to other nodes, when the number of reply agreement information obtained from other nodes is greater than or equal to a set number, the node with control authority transfers the control authority to the node applying for the control authority, and the node can control the BAS system only after the control authority is transferred to the node. Through the mechanism, the malfunction caused by multiple nodes simultaneously controlling the BAS system can be avoided, and the security is improved.
