Description

Technical Field

[0001] This application relates to elevator technology, and more particularly to a communication system for elevator systems, a communication method for elevator call systems, and a computer-readable storage medium for implementing the method. Background Technology

[0002] In an elevator calling system, wireless modules are deployed on each floor to perform calling operations associated with their respective floors. Typically, the wireless communication modules of each floor are deployed along the elevator shaft, and each wireless module, or node, can establish wireless communication connections with wireless modules or nodes on adjacent floors. This cascading connection method enables communication between the main controller unit or elevator control cabinet and any wireless module, or communication between any pair of wireless modules. Normally, the signal will experience a delay of approximately tens of milliseconds after being relayed through multiple nodes. Therefore, when the signal transmission path is long, the accumulated delay becomes considerable. For example, in a 100-story building, the delay will exceed one second when the signal is transmitted from the top floor to the bottom floor. Such a high level of delay is unacceptable for an elevator calling system. Summary of the Invention

[0026] The present application will now be described more fully with reference to the accompanying drawings, which illustrate exemplary embodiments thereof. However, the present application may be implemented in various forms and should not be construed as being limited to the embodiments given herein. The foregoing embodiments are intended to make the disclosure herein complete and thorough, so as to more fully convey the scope of protection of the present application to those skilled in the art.

[0027] In this specification, terms such as “comprising” and “including” indicate that, in addition to having the units and steps that are directly and explicitly stated in the specification and claims, the technical solution of this application does not exclude the presence of other units and steps that are not directly or explicitly stated.

[0028] Unless otherwise specified, terms such as “first” and “second” do not indicate the order of units in terms of time, space, size, etc., but are merely used to distinguish between units.

[0029] In this specification, terms such as "direct communication connection" should be understood as the situation where communication signals are directly transmitted between two units. Unless otherwise specified, terms such as "communication connection" and "direct communication connection" may be used interchangeably in this specification.

[0030] Figure 1 This is a schematic block diagram of a communication system for an elevator system according to some embodiments of this application.

[0031] See Figure 1 The communication system 10 shown includes a master node 110 and wireless modules 1201-1220 (in the following description, the terms "wireless module" and "node" are used interchangeably). Figure 1 In the diagram, a solid line connecting the units represents a direct communication connection between them.

[0032] For example, the master node can be used as a communication interface for a main controller unit or an elevator control cabinet, and the wireless module can be used as a communication interface for an outbound call control unit.

[0033] For example, wireless modules 1201-1220 are deployed on floors #1-#20 respectively to perform elevator call operations associated with their respective floors (e.g., receiving user call requests for the elevator, displaying the elevator's current floor, and presenting a notification message when the elevator arrives at the called floor). In one example, the wireless module of the outbound call control unit can be deployed inside the elevator shaft, while the control module is integrated with the display module and positioned near the elevator entrance on each floor. In the following description, unless otherwise specified, the outbound call control unit and its wireless module are interchangeable.

[0034] like Figure 1 As shown, floors #1-#20 are divided into four floor groups #A-#D, each containing five floors. It should be noted that... Figure 1 The division of floors into four groups shown is merely an example. Floors can be divided in a non-uniform manner depending on the actual application, and the number of groups is not limited to a specific value.

[0035] The wireless module can be divided into multiple communication node groups corresponding to different floor groups. Figure 1 In the example shown, wireless modules 1201-1220 are divided into four communication node groups 120A-120D. Among them, wireless modules 1201-1205 belong to unit group 120A, wireless modules 1206-1210 belong to unit group 120B, wireless modules 1211-1215 belong to unit group 120C, and wireless modules 1216-1220 belong to unit group 120D.

[0036] In some embodiments of this application, for each communication node group, one wireless module can be designated as the first node (hereinafter referred to as the "guide node") and the other wireless modules can be designated as the second nodes (hereinafter referred to as "ordinary nodes"). The main difference between the guide node and the ordinary nodes lies in the range of objects to which direct communication connections can be established. Specifically, within each communication node group, the guide node and the ordinary nodes are connected together through a star network structure. The guide node, as the central node of the star network structure, is configured to establish direct wireless communication connections with each ordinary node within the same communication node group, while ordinary nodes can be configured to establish direct wireless communication connections only with the guide node within the same communication node group. On the other hand, the guide node is also configured to establish direct wireless communication connections with the guide nodes within the communication node groups of adjacent floor groups. Technologies that can be used to establish wireless communication connections include, but are not limited to, Wi-Fi communication technology, Bluetooth communication technology, and Zigbee communication technology.

[0037] It should be noted that within each communication node group, in addition to establishing a direct wireless communication connection with the leader node in the same group, ordinary nodes can also establish a direct wireless communication connection with one or more other ordinary nodes in the same group.

[0038] by Figure 1 In the example shown, wireless modules 1205, 1210, 1215, and 1220 can be set as guide nodes in their respective communication node groups, while other wireless modules in the communication node groups can be set as ordinary nodes. In communication node groups 120A-120D, wireless modules 1205, 1210, 1215, and 1220, which serve as guide nodes, are connected in a cascaded manner. In each communication node group 120A-120D, a direct communication connection is established between the guide node and the ordinary nodes.

[0039] While any wireless module within each communication node group can be used as a guide node, designating a wireless module at a fixed location within each communication node group as a guide node is advantageous for inter-group signal transmission (i.e., signal transmission between different communication node groups). Alternatively, a wireless module deployed on the first or last floor of a floor group can be designated as a guide node.

[0040] like Figure 1 As shown, the master node 110 can establish a direct communication connection with the wireless module 1220, which can be wireless or wired. Although any guiding node can be designated to establish a communication connection with the master node, choosing the one spatially closest to the master node is generally advantageous because it reduces the communication distance between them. Figure 1For example, assuming the master node 110 is located on the highest floor #20, it is reasonable to configure it to establish a communication connection with the boot node 1220.

[0041] When the master node sends a signal indicating the elevator's operating status (such as its current floor) to a wireless module acting as a signal receiver, the signal is first transmitted outside the group (i.e., between the master node and communication node groups, and between different communication node groups). Subsequently, when the signal reaches the guide node within the receiver's communication node group, if the receiver is a guide node, the transmission process is complete; otherwise, the signal is transmitted within the group (i.e., from the guide node to a regular node). On the other hand, when a wireless module acting as a signal sender sends a signal to the master node (e.g., a user's elevator call request), if the wireless module is a regular node, the signal is first transmitted within the group to the guide node, and then outside the group to the master node; if the wireless module is a guide node, the signal is directly transmitted outside the group to the master node.

[0042] The communication method is similar for any pair of multiple wireless modules. Specifically, if the pair of wireless modules belongs to the same communication node group, signal transmission can be completed only through intra-group transmission. If the pair of wireless modules belongs to different communication node groups, inter-group transmission is essential.

[0043] In a typical elevator call system, the master node and wireless module are cascaded together, meaning the signal transmission path includes all nodes between the sender and receiver. While latency during signal forwarding can be reduced by improving hardware specifications, this inevitably increases manufacturing costs. Compared to cascading, the combination of external and internal group transmission described above can significantly reduce the number of nodes forwarding signals at a lower implementation cost, thus significantly reducing transmission latency. Furthermore, the grouping of the wireless module and the combination of internal and external group transmission can greatly extend the communication distance and meet the real-time requirements of long-distance communication. Moreover, when a communication failure occurs, the faulty node can be quickly located by first checking the communication node group and then checking the wireless modules within the group.

[0044] Typically, the effective signal transmission distance or coverage area of ​​a wireless module cannot extend to the entire floor. Therefore, it is advantageous to consider the signal coverage of both the guide node and regular nodes when dividing floor groups or wireless modules. Furthermore, the latency limitations of signal transmission between floors (e.g., the maximum allowable delay time) are also a factor to consider.

[0045] Optionally, in some embodiments, the settings of the guiding node and ordinary nodes within each communication node group are dynamically adjustable. In one embodiment, the master node 110 is configured to change the settings of one or more guiding nodes and ordinary nodes within a communication node group in response to a setting-type event. Optionally, examples of setting-type events include, but are not limited to, a failure of the currently set guiding node or a change in the setting of the guiding node in a communication node group of an adjacent floor group. By utilizing the above-described mechanism of dynamically updating the guiding node settings, when a guiding node fails or malfunctions, an ordinary node within the communication node group can be selected as the new guiding node to ensure data transmission paths between groups, thereby improving the robustness of the system.

[0046] Figure 2 This is a schematic block diagram of an elevator call system according to some other embodiments of this application.

[0047] See Figure 2 The elevator call system 20 shown includes a master node or elevator control cabinet 210 and wireless modules 2201-2220. Similarly, in Figure 2 In the diagram, a solid line connecting the units represents a direct communication connection between them.

[0048] The following mainly describes Figure 2 The illustrated embodiments and Figure 1 The differences between the embodiments shown are as follows.

[0049] See Figure 2 For example, wireless modules 2205, 2210, 2215, and 2220 are configured as leader nodes within their respective communication node groups 220A-220D, while other wireless modules within the communication node groups are configured as ordinary nodes. Similarly, the master node 210 can establish a direct wireless or wired communication connection with wireless module 2220.

[0050] like Figure 2 As shown, the guide node is configured to establish a direct wireless communication connection with the guide node in the communication node group of the adjacent floor group. However, with Figure 1 The difference is that, in Figure 2 In the illustrated embodiment, within each communication node group 220A-220D, the guiding node is connected to the ordinary nodes in the same group via a cascading method.

[0051] exist Figure 2In the illustrated embodiment, when the master node sends a signal indicating the elevator's operating status to the wireless module (which acts as the signal receiver), the signal is first transmitted outside the group. Subsequently, when the signal reaches the guiding node within the communication node group to which the receiver belongs, if the receiver is the guiding node, the transmission process is completed; otherwise, the signal is transmitted to ordinary nodes in a cascade manner within the group. On the other hand, when the wireless module (which acts as the signal sender) sends a signal to the master node, if the wireless module is an ordinary node, the signal is first transmitted to the guiding node in a cascade manner within the group, and then transmitted outside the group to the master node. If the wireless module is the guiding node, the signal is directly transmitted outside the group to the master node.

[0052] The communication method is similar for any pair of multiple wireless modules. For example, if the pair of wireless modules belongs to the same communication node group, the signal transmission can be completed within the group by cascading. If the pair of wireless modules belongs to different communication node groups, the signal is transmitted between the communication node groups through inter-group transmission.

[0053] The above communication methods also have Figure 1 The illustrated embodiment offers various advantages. Furthermore, when the guiding node is cascaded with other nodes in the same group, the effective transmission distance between nodes can be reduced, thereby lowering power consumption and hardware costs.

[0054] exist Figure 1 and 2In the communication system shown, each node is implemented using a communication module or a wireless module with wireless communication capabilities. However, this specific implementation is merely exemplary and should not be construed as an essential feature when applying the above embodiments or variations thereof. That is, the content disclosed in this application is also applicable to communication systems where some nodes within an elevator system transmit signals via wired means (i.e., the communication system includes both wireless and wired modules). For example, when some nodes transmit signals via wired means, the wireless and wired modules can be divided into multiple communication node groups. In other words, a communication node group can contain only wireless modules or both wireless and wired modules. By setting a first node and a second node and configuring their corresponding functions, communication between the main node and any wireless module within a communication node group, or communication between a pair of wireless modules, can be achieved. For this purpose, the wired module can be configured to provide a wired communication connection on the communication link between the main node and any wireless module within a communication node group, or on the communication link between a pair of wireless modules. Accordingly, the wireless connection between the bootstrap node and ordinary nodes should be broadly understood to include all connections via wireless channels and connections via both wireless and wired channels. Similarly, the wireless connection between ordinary nodes should also be broadly understood to include all connections via wireless channels and connections via both wireless and wired channels.

[0055] Figure 3 This is a schematic block diagram of an elevator control system according to some other embodiments of this application.

[0056] Figure 3 The elevator control system 30 shown includes a communication system 310, which may, for example, have the above-mentioned communication system. Figure 1 and 2 The various features of the described embodiments. It should be noted that, to avoid redundancy, Figure 3 Other components in the elevator control system (such as PLC, frequency converter, and speed control system) are not shown.

[0057] Figure 4 This is a flowchart of a communication method for an elevator system according to some other embodiments of this application.

[0058] Exemplary but not required, the following are examples Figure 1 The following description will take the communication system shown in Figure 2 as an example. It will be readily understood by those skilled in the art that... Figure 4 The methods shown are not limited to the specific examples of the communication systems described in this specification.

[0059] like Figure 4 As shown, the communication method for elevator systems includes the following steps:

[0060] Step 401: Divide the wireless modules of the communication system into at least two communication node groups. Each wireless module within a group is deployed at multiple locations within the elevator system (e.g., on each floor of the corresponding floor group). Still using... Figure 1 For example, floors #1-#20 are divided into four floor groups #A-#D, each containing five floors. Wireless modules 1201-1220 are divided into four communication node groups 120A-120D, corresponding to floor groups #A-#D respectively. The wireless modules within each communication node group are deployed on the corresponding floors. For example, for communication node group A, wireless modules 1201-1205 are deployed on floors #1-#5 respectively, and so on for the other communication node groups B and C.

[0061] Step 402: Within each communication node group, set one of the wireless modules as the bootstrap node (e.g., Figure 1 Nodes 1205, 1210, 1215, and 1220 in the data and Figure 2 (Nodes 2205, 2210, 2215, and 2220 in the diagram) and configure other wireless modules as ordinary nodes. The meaning and characteristics of boot nodes and ordinary nodes have been described above and will not be repeated here.

[0062] Step 403: Specify one of the multiple boot nodes as the node that establishes a direct communication connection with the master node. Optionally, the boot node that is spatially closest to the master node can be specified (e.g., the one closest to the master node in space). Figure 1 The boot node 1220 and Figure 2 The guiding node 2220 in the middle is used as the node to establish a direct communication connection.

[0063] Step 404: Perform communication configuration for the bootstrap node and regular nodes within each communication node group. Specifically, configure the bootstrap node (e.g., ...) Figure 1 Nodes 1205, 1210, 1215, and 1220 in the data and Figure 2 The nodes 2205, 2210, 2215, and 2220 in the dataset are configured as follows:

[0064] • Able to establish wireless communication connections with ordinary nodes belonging to the same communication node group (e.g.) Figure 1 The direct connection method shown and Figure 2 (The cascaded connection method shown)

[0065] • It can establish a direct wireless communication connection with the guide node in the communication node group of the adjacent floor group.

[0066] Through configuration, communication can be achieved between the master node and any node within a communication node group, or between any pair of nodes. When the master node, acting as the signal sender, transmits a signal to the wireless module, acting as the signal receiver, the signal is first transmitted outside the group (e.g., in...). Figure 1 and 2 In this process, the signal is transmitted between the master node and communication node groups 120D or 220D, and between different communication node groups 120A-120D or 220A-220D. Then, when the signal reaches the guiding node within the communication node group to which the receiver belongs (e.g., assuming communication node group 120A), if the receiver is the guiding node (e.g., assuming node 1205), the transmission process is complete; otherwise, the signal is transmitted within the group (i.e., from guiding node 1205 to one of the ordinary nodes 1201-1204). On the other hand, when a wireless module acting as a signal sender transmits a signal to the master node, if the wireless module is an ordinary node (e.g., assuming...), the transmission process is complete. Figure 1 Node 1201 or Figure 2 If the signal is 2207 in the group, then the signal is first transmitted within the group to the bootstrap node (e.g., 2207). Figure 1 Node 1205 or Figure 2 (2210 in the middle), and then transmitted to the master node through the external group (e.g., in the middle). Figure 1 The process proceeds sequentially through nodes 1205, 1210, 1205, and 1220 to reach the master node 110. Figure 2 The signal is transmitted from node 2210, 2205 and 2220 to the master node 210. If the wireless module is a pilot node (for example, assume it is node 1205), the signal is transmitted directly to the master node via external transmission (for example, via nodes 1205, 1210, 1215 and 1220 to the master node 110).

[0067] The communication method is similar for any pair of wireless modules among multiple wireless modules. This will not be elaborated further here.

[0068] Optionally, Figure 4 The method shown may also include the following steps:

[0069] Step 405: Monitor whether a set type of event has occurred. If it has, proceed to step 406; otherwise, continue monitoring. Examples of the set type of event include, but are not limited to, a failure of the currently set guide node or a change in the guide node settings within the communication node group of an adjacent floor group.

[0070] Step 406: Change the settings of the bootstrap node and regular node associated with the monitored event type. For example, suppose... Figure 1If the boot node 1205 fails, then in communication node group 120A, node 1204 can be set as the boot node and node 1205 can be set as a normal node; for example, assuming in Figure 1 In the communication node group 120D, the guiding node is changed from the original node 1220 to node 1216. In order to reduce the wireless communication distance between node 1216 and the guiding node in the adjacent communication node group 120C, the guiding node in the communication node group 120C can be changed to node 1211. Correspondingly, the guiding nodes in the communication node groups 120B and 120A are changed to nodes 1206 and 1201, respectively.

[0071] Optionally, the above method steps can be performed by the master node (e.g., Figure 1 The master node 110 and Figure 2 Execute on the master node 210.

[0072] According to another aspect of this application, a computer-readable storage medium is also provided, on which a computer program is stored, which, when executed by a processor, can realize the above-described functions. Figure 4 The method includes one or more steps.

[0073] The term "computer-readable storage medium" as used herein includes various types of computer storage media, and can be any available medium accessible to a general-purpose or special-purpose computer. For example, a computer-readable storage medium may include RAM, ROM, EPROM, E2PROM, registers, hard disks, removable disks, CD-ROMs or other optical disc storage, magnetic disk storage or other magnetic storage devices, or any other temporary or non-temporary medium capable of carrying or storing desired program code units having the form of instructions or data structures and accessible by a general-purpose or special-purpose computer, or a general-purpose or special-purpose processor. As used herein, disks typically magnetically copy data, while discs optically copy data using lasers. Combinations of the above should also be included within the scope of protection of computer-readable storage media. An exemplary storage medium is coupled to a processor so that the processor can read and write information from / to the storage medium. In an alternative, the storage medium may be integrated into the processor. The processor and storage medium may reside in an ASIC. The ASIC may reside in a user terminal. In an alternative, the processor and storage medium may reside as discrete components in the user terminal.

[0074] Those skilled in the art will understand that the various illustrative logic blocks, modules, circuits, and algorithm steps described herein can be implemented as electronic hardware, computer software, or a combination of both.

[0075] To demonstrate the interchangeability between hardware and software, various illustrative components, blocks, modules, circuits, and steps have been generally described above according to their functionality. Whether such functionality is implemented in hardware or software depends on the specific application and the design constraints imposed on the overall system. Those skilled in the art can implement the described functionality in varying ways for specific applications; however, such implementation decisions should not be construed as departing from the scope of this application.

[0076] It should be pointed out that, although Figure 1-4 The embodiments shown are described using examples of elevator call applications, but this does not mean that the content disclosed in this application is only applicable to elevator call applications. In fact, the content disclosed in this application is applicable to data transmission in various elevator-related applications; that is, the transmitted data can be not only related to call operations but also other types of data (such as elevator diagnostic data, user distress signals, etc.). Furthermore, the method of dividing the wireless module into multiple communication node groups corresponding to floor groups in the above embodiments is merely exemplary, and dividing the wireless module based on floors is not necessary. For example, in some applications, the elevator system may need to deploy more than one wireless module within a single floor, or it may need to deploy wireless modules between floors. In these cases, the wireless modules deployed at different locations in the elevator system can be divided into different communication node groups according to various characteristics (such as aggregation degree, node communication capability, and communication guarantee priority).

[0077] Although only some specific embodiments of this application have been described, those skilled in the art will understand that this application can be implemented in many other forms without departing from its spirit and scope. Therefore, the examples and embodiments shown are to be considered illustrative rather than restrictive, and various modifications and substitutions may be made without departing from the spirit and scope of this application as defined by the appended claims.

[0078] The embodiments and examples presented herein are provided to best illustrate embodiments according to the present technology and its particular applications, thereby enabling those skilled in the art to implement and use the application. However, those skilled in the art will understand that the above description and examples are provided for ease of illustration and example only. The descriptions presented are not intended to cover all aspects of the application or to limit the application to the precise forms disclosed.
