Description

Technical Field

[0001] This invention relates to the technical field of elevators, and more particularly to an outbound call communication method, device, and storage medium. Background Technology

[0002] In residential buildings, office buildings, shopping malls and other buildings, multiple elevators are often installed for users to go up and down floors and move goods.

[0003] Elevator call buttons (also known as call panels) can be installed on each floor of the building to provide functions such as call operation and display of car status (such as the floor the car is on, the direction the car is moving, etc.). The elevator controller will periodically or irregularly exchange data with each call button, such as status data.

[0004] In high-rise buildings, there are a large number of outbound callers and corresponding communication nodes. To expand communication nodes, the current methods are mostly to connect multiple communication cables or add trunks. However, adding communication cables increases the cost of installation and maintenance, while the trunk method requires packaging and filtering the data under each trunk during communication, resulting in different data structures under each trunk, higher maintenance costs, and poor scalability. In particular, when the outbound caller undergoes product function upgrades or communication protocol changes, extensive code modifications are required, increasing the development workload. Summary of the Invention

[0005] In view of this, the present invention provides an outbound call communication method, device and storage medium to maintain installation and maintenance costs when communicating with multiple outbound callers in an elevator.

[0008] Query the communication voltage range configured for the outbound caller in the target group, and use it as the target voltage range;

[0009] Power is supplied to each of the call buttons via the power cable according to the target voltage range. The call button is used to connect to the communication cable for communication when it detects that the target voltage value of the power cable is within the communication voltage range configured for the current call button.

[0010] A second aspect of the present invention provides an outbound call communication device applied to an elevator, the elevator including outbound callers distributed on each floor, each of the outbound callers being connected to the same power cable and the same communication cable, the device comprising:

[0012] The target voltage range query module is used to query the communication voltage range configured for the outgoing caller in the target group, as the target voltage range;

[0013] A target voltage range power supply module is used to supply power to each of the call buttons through the power cable according to the target voltage range. The call button is used to connect to the communication cable for communication when it detects that the target voltage value of the power cable is within the communication voltage range configured for the current call button.

[0014] A third aspect of the present invention provides an electronic device, the electronic device comprising:

[0015] At least one processor; and

[0016] A memory communicatively connected to the at least one processor; wherein,

[0017] The memory stores a computer program that can be executed by the at least one processor, the computer program being executed by the at least one processor to enable the at least one processor to perform the outbound communication method as described in the first aspect above.

[0018] A fourth aspect of the present invention provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the outbound call communication method as described in the first aspect above.

[0019] A fifth aspect of the present invention provides a computer program product comprising a computer program that, when executed by a processor, implements the outbound call communication method as described in the first aspect above.

Power is supplied to each call button through the power cable according to the target voltage range. When a call button detects that the target voltage value of the power cable is within the communication voltage range configured for the current call button, it connects to the communication cable for communication. This embodiment uses the same communication cable to extend multiple communication nodes and groups to communicate with each call button. The communication cable is not modified; communication nodes are directly added, resulting in a simple design, maintaining communication reliability, and lower installation and maintenance costs.

[0021] Furthermore, the addition of communication nodes mainly relies on changes in the power supply voltage to maintain the load-carrying capacity of the hardware circuitry.

[0038] Example 1

[0039] See Figure 1The diagram illustrates a flowchart of an outbound call communication method provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where elevator active control supplies voltage to multiple outbound callers, selectively communicates with some outbound callers, and the method can be executed by an outbound call communication device. This outbound call communication device can be implemented in hardware and / or software and can be configured in an electronic device. Figure 1 As shown, the method includes:

[0040] Step 101: Select the outbound call group to be communicated from the preset multiple outbound call groups as the target group.

[0041] Different types of buildings, especially high-rise buildings, have different transportation needs for people, pets, and goods. Therefore, different types of elevators can be deployed in buildings according to different transportation needs, such as passenger elevators, freight elevators, sightseeing elevators, etc. The method in this embodiment can be applied to various types of elevators.

[0042] An elevator is a complex system, and its structure varies among different types of elevators.

[0043] In one example, the components of a certain type of elevator include a controller (also known as an elevator control system), call buttons distributed on each floor, a car, a traction machine, a control cabinet, a speed governor, a door operator, a car frame, car doors, counterweight guide rails, car guide rails, guide rail supports, traveling cables, counterweight devices, compensating chains (cables), landing doors, guiding devices for compensating chains (cables), buffers, etc.

[0044] In some types of elevators, the traction machine, control cabinet, speed governor, traveling cable, etc., can be omitted.

[0045] These devices can be divided into different sets according to their functions, thus forming various subsystems that support the operation of the elevator. The controller is connected to multiple systems of the elevator via wired means such as serial port or serial clock line (SCL). The controller monitors each system and controls the operation of each subsystem, so that the car moves in the hoistway and reaches each floor of the building.

[0046] In one example, the controller includes a door system, a frequency conversion system, a call system, and a traction system. The door system controls the elevator doors. The car is equipped with a car door, and the elevator has hall doors on each floor. The elevator doors include the car door and the hall doors on each floor. The car door and the hall door are of the same type and open / close simultaneously. The frequency conversion system controls the frequency converter. The call system controls the logic of internal call (calling the elevator from inside the car) and external call (calling the elevator from the hall). The traction system controls the car to move vertically (vertically upward or vertically downward) in the hoistway.

[0047] The elevator manager or owner can choose whether to install an edge computing node on the elevator based on factors such as the elevator's load status. If no edge computing node is installed, the controller maintains the original control logic and does not affect the normal operation of the elevator. If an edge computing node is installed, a suitable computing device can be selected as the elevator's edge computing node according to the needs. The edge computing node is combined with the original controller to form a new controller and redefine the elevator's control logic.

[0048] Generally, edge computing nodes are computing devices with strong computing capabilities, such as computers, servers, or embedded devices. In addition, depending on the different intelligent services, edge computing nodes can be equipped with graphics processing units (GPUs) or embedded neural network processors (NPUs).

[0049] Edge computing nodes refer to new business platforms built at the network edge near elevators, providing storage, computing, and network resources. This allows some critical business applications to be offloaded to the edge of the access network, reducing bandwidth and latency losses caused by network transmission and multi-level forwarding. Located between the user and the cloud (server), edge computing nodes are closer to the user (data source) than traditional cloud computing, featuring miniaturization, distribution, and user-friendliness. Massive amounts of data (such as audio data) no longer need to be uploaded to the cloud for processing; data processing can be performed at the network edge, reducing request response time, reducing network bandwidth, and ensuring data security and privacy.

[0050] In addition, edge computing nodes can implement algorithm functions and model inference, communicate with the original controller, and provide the original controller with artificial intelligence (AI) and complex computing capabilities; edge computing can also communicate with the cloud to realize algorithm functions and model updates, and relay the original controller function calls, etc.

[0051] Under normal circumstances, such as Figure 2 and Figure 3 As shown, the controller in the elevator is connected to each call button via a serial communication bus. The serial communication bus consists of four cables, two of which are power cables that provide power to the call buttons. One of these power cables is the positive wire, and the other is the ground wire. The other two cables are serial communication cables.

[0052] like Figure 2As shown, the controller is equipped with components such as a power supply, a communication module, a group communication control module, and an MCU (Microcontroller Unit). The MCU is the control center of the controller, responsible for interacting with various components and executing various functions of the controller. The power supply is connected to the power cable and supplies power to the power cable. The communication module is connected to the communication cable and communicates with the caller. The group communication control module provides control and management services for communication with the callers in each call group.

[0053] like Figure 3 As shown, each caller is equipped with components such as a power management circuit, a communication module, an MCU, a display, and buttons. The MCU is the control center of the caller, responsible for interacting with various components and executing various functions of the caller. The power management circuit is connected to the power cable, supplies power to the caller, and manages the power supply. The communication module is connected to the communication cable and communicates with the controller. The display shows various information of the caller for users to browse. The buttons serve as input ports for users to input control operations.

[0054] During normal elevator operation, all call buttons are connected to the same power cable and the same communication cable. That is, each call button is powered by the same (two) power cables and communicates using the same (two) communication cables.

[0055] In this embodiment, multiple outbound callers can be divided into multiple outbound call groups in advance according to the communication service requirements. Each outbound call group has multiple outbound callers, and multiple outbound callers in the same outbound call group can communicate and exchange data with the controller at the same time.

[0056] The elevator controller can determine a specific outbound call group from multiple preset outbound call groups according to the communication service requirements, and this group is denoted as the target group.

[0057] For example, if the communication service requirement is periodic polling, then communication can be carried out with each outbound call group in sequence according to the coding order of multiple call groups. In this case, each outbound call group is set as the target group in sequence.

[0058] Step 102: Query the communication voltage range configured for the outbound callers in the target group, and use it as the target voltage range.

[0059] In this embodiment, the communication voltage range can be configured for each outbound caller in each outbound call group in advance according to the communication service requirements, and the mapping relationship between the outbound callers in the outbound call group (identified by information such as ID) and the communication voltage range can be recorded using tables or other methods. The mapping relationship is stored in the controller and distributed to each outbound caller.

[0060] The communication voltage range refers to the range of voltages at which all outgoing callers in the corresponding outgoing call group initiate communication.

[0061] It should be noted that the normal operating voltage range of the outbound caller is relatively wide. The communication voltage range configured for the outbound callers in each outbound call group is within the normal operating voltage range of the outbound caller and does not affect the operation of the outbound caller.

[0062] For example, a certain outbound caller has a rated voltage of 24V and an allowable deviation of ±20%. The operating voltage range between 19.2V and 28.8V is the communication voltage range configured for the outbound callers in each outbound call group, and it does not affect the outbound callers.

[0063] When determining the target group, the communication voltage range configured for the outgoing callers in that target group can be queried in the local table of the controller and recorded as the target voltage range.

[0064] Step 103: Power each call button through the power cable according to the target voltage range.

[0065] The elevator controller has a variable output power supply. The power output voltage is adjusted according to the target voltage range and supplied to each call button via power cables, so that the power cable voltage detected by the call buttons in the target group is within the target voltage range.

[0066] Each caller detects the voltage of the power cable and records it as the target voltage value. Some callers are used to connect to the communication cable for communication when the target voltage value of the power cable is within the communication voltage range configured for the current caller.

[0067] In high-rise buildings, there are many outbound call devices, all of which are connected to a serial communication bus, increasing the number of communication nodes. To ensure communication reliability, the number of communication interfaces is usually expanded.

[0068] Elevator external call communication typically uses CAN (Controller Area Network), RS485, transformer isolation, or other methods. When there are many communication nodes and the transmission distance is long, the serial communication bus may cause some problems. For example, it is easily affected by external interference, the increase in communication nodes affects the load capacity of the hardware communication circuit, the increase in communication nodes affects the signal reflection of the serial communication bus, the increase in communication nodes affects the resistance value of the terminal matching resistor, and so on.

[0069] To expand communication nodes, it is generally done by adding communication interfaces. However, adding interfaces increases the resource requirements of the controller and requires additional communication cables, which significantly increases the overall cost.

[0070] In practical applications, the design for increasing the communication nodes of outbound callers may include the following:

[0071] 1. Group the callers. Each group of callers uses the same independent communication cable. Multiple groups of callers use multiple independent communication cables.

[0072] For example, such as Figure 4 As shown, each group consists of 24 call buttons (communication nodes) on every floor, and each group of 24 call buttons (communication nodes) shares a single independent communication cable.

[0073] Grouping can ensure communication reliability, but multiple communication cables will increase costs, and subsequent maintenance costs will also increase accordingly.

[0074] 2. Add relays to the group for expansion.

[0075] For example, such as Figure 5 As shown, each group consists of outbound callers (communication nodes) covering 24 floors, and 23 outbound callers (communication nodes) are used. The last outbound caller (communication node) in each group serves as the relay for the next group.

[0076] The relay method saves the cost of repeated communication cables compared to the group method. However, adding more communication cables will increase the cost of installation and maintenance. Problems such as load capacity, node reflection, and terminal resistance transformation still exist when the number of communication nodes increases.

[0077] Furthermore, the relay method requires packaging and filtering data under each relay during communication, resulting in different data structures under each relay. This leads to higher maintenance costs and poor scalability. In particular, when the outbound caller undergoes product function upgrades or communication protocol changes, extensive code modifications are required, increasing the development workload.

[0078] 3. The outbound callers are distributed in a distributed manner. The outbound callers are divided into ordinary outbound callers and special outbound callers. The special outbound callers collect data from the ordinary outbound callers and package and summarize the data from the ordinary outbound callers.

[0079] Distributed systems are essentially a combination of outbound calls and trunk expansion, which can solve problems such as occasional interference and data filtering. However, issues such as load capacity, node reflection, and terminal resistance transformation still exist when the number of nodes increases.

[0080] 4. Group outbound callers and switch access buses. Each time a communication occurs, it does not communicate with all outbound callers, but with a group of inbound and outbound callers.

[0081] The group switching method places high demands on the bus, making its production more complex and costly. At the same time, the bus's versatility is also poor.

[0082] In this embodiment, the elevator includes call buttons distributed on each floor. Each call button is connected to the same power cable and the same communication cable. During communication, a target call group is selected from multiple preset call groups. Each call group contains multiple call buttons. The communication voltage range configured for the call buttons in the target group is queried and selected as the target voltage range. Power is supplied to each call button through the power cable according to the target voltage range. When a call button detects that the target voltage value of the power cable is within the communication voltage range configured for the current call button, it connects to the communication cable for communication. This embodiment uses the same communication cable to extend multiple communication nodes and groups to communicate with each call button. The communication cable is not modified; communication nodes are directly added, resulting in a simple design, maintaining communication reliability, and lower installation and maintenance costs.

[0083] Furthermore, the addition of communication nodes mainly relies on changes in the power supply voltage to maintain the load-carrying capacity of the hardware circuitry.

[0084] Example 2

[0085] See Figure 6 The diagram illustrates a flowchart of an outbound call communication method according to Embodiment 2 of the present invention. This embodiment adds an outbound call grouping mode operation based on the previous embodiments. Figure 6 As shown, the method includes:

[0086] Step 601: Synchronously start the outbound call group mode with each outbound caller.

[0087] During elevator installation, maintenance, and other time points, the elevator controller and each external caller of the elevator synchronously start the external call group mode. The external call group mode is used for initialization operations such as dividing each external caller into multiple external call groups, configuring the communication voltage range for the external callers in each external call group, and configuring the original voltage value for the communication voltage range.

[0088] To facilitate initialization, each caller can be connected to a communication cable in the call group mode, enabling each caller to communicate with the controller.

[0089] Step 602: In the outbound call grouping mode, divide each outbound caller into multiple outbound call groups.

[0090] In the outbound call group mode, the controller can divide each outbound caller into multiple outbound call groups according to the communication service requirements, using methods such as sequence and interval. The number of outbound callers in each outbound call group can be equal or different, and this embodiment does not impose any restrictions on this.

[0091] In one approach to segmentation, in the outbound call grouping mode, each outbound caller is sorted into a call sequence according to the order of each floor. The call sequence is divided into multiple outbound call groups using equal or unequal division methods to keep the outbound callers in the same outbound call group continuous. Since there is a voltage drop in the power cable and the communication voltage range is continuous, keeping the outbound callers in the same outbound call group continuous by floor can make it easier to keep in line with the communication voltage range, which can improve communication efficiency.

[0092] For example, such as Figure 7 As shown, all 72 floor call points (communication nodes) are connected to the same communication cable, and each call point (communication node) is divided into a call group every 24 consecutive floors.

[0093] Step 603: In the outbound call group mode, configure the communication voltage range for the outbound callers in multiple outbound call groups.

[0094] In the outbound call group mode, the controller can configure independent communication voltage ranges for outbound callers in multiple outbound call groups using continuous or intermittent methods according to the communication service requirements. The term "independent" means that the communication voltage ranges configured for outbound callers in multiple outbound call groups are different.

[0095] In one embodiment of the present invention, step 603 may include the following steps:

[0096] Step 6031: In the outbound call group mode, calculate the bus voltage drop of the outbound caller in the power cable in each outbound call group.

[0097] In practical applications, such as Figure 8 As shown, the communication cables between each caller (communication node) have a resistance R. The resistance R is not negligible, which causes voltage loss (referred to as line loss) in the power cable at each caller (communication node), resulting in voltage drop (i.e., voltage reduction).

[0098] In the outbound call group mode, the controller can calculate the line loss of the outbound callers in each outbound call group in the power cable based on the distribution information of the outbound callers on each floor, the physical parameters of the power cable, and other factors, and calculate the corresponding voltage drop value, which is recorded as the bus loss voltage drop.

[0099] In one method of calculating bus voltage drop, in the external call group mode, information pre-entered by users such as maintenance personnel can be queried locally on the controller or in the cloud. This information includes the number of power cables, the resistivity of the power cables, the current value of the external call device, and the height of the distance between two adjacent floors.

[0100] The product of quantity, height, and resistivity is calculated to obtain the line loss resistance in the power cable between two adjacent call points (i.e., two adjacent floors).

[0101] Calculate the product of the current value and the line loss resistance to obtain the sub-line loss voltage drop between two adjacent call buttons in the power cable.

[0102] For example, a certain type of communication cable used in the elevator includes a positive wire and a ground wire, and the cross-sectional area of ​​each communication cable is 0.75 mm². 2 The corresponding resistivity is 25.1 (Ω / km) at 20℃, and the current value of the call button is 3m above the height of the two adjacent floors.

[0103] The line loss resistance between two adjacent call buttons in the power cable is R = (2 × 3 × 25.1) / 1000 = 0.1506Ω. The rated output voltage of a certain call button is 24V and the rated output current is 40mA. Then the line loss voltage drop generated by connecting a call button is U = (40 × 0.1506) / 1000 = 7.53mV.

[0104] The voltage drops of the corresponding sub-lines of the callers in the same caller group are added together to obtain the total voltage drop of the caller in the power cable of the caller in the caller group.

[0105] by Figure 8 Taking the callers in the first call group, located between floors 1-24, as an example, assuming a constant current of 40mA for each caller, then:

[0106] Voltage drop of the sub-line of the external caller between floors 1 and 2: U 1-2 =(40×0.1506) / 1000≈6.02mV;

[0107] Voltage drop of the sub-line of the external caller located between the 2nd and 3rd floors: U 2-3 =(2×40×0.1506) / 1000≈12.05mV;

[0108] ...

[0109] Voltage drop of the sub-line of the external caller located between floors 23 and 24: U 23-24 =(23×40×0.1506) / 1000≈138.48mV.

[0110] The voltage drop across the sub-lines of the callers located between floors 1-24 is summed to obtain the bus voltage drop across the power cable for the caller in the first call group: U = U 1-2 +U 2-3 +……+U 23-24 =(1+2+…+23)×(40×0.1506) / 1000≈1.66V.

[0111] Step 6032: Round up the bus voltage drop to obtain the voltage difference.

[0112] In practical applications, the bus voltage drop can be rounded up to obtain the voltage difference. This voltage difference can be used as a metric to divide the communication voltage range, resulting in a certain voltage redundancy and reducing the probability of erroneous operation.

[0113] For example, if the bus voltage drop is 1.66V, then the voltage difference can be rounded up to 2V.

[0114] When the distribution information of callers on each floor, the physical parameters of the power cables, and the number of callers in the call group are the same, the bus voltage drop generated by the callers in the call group on the power cables is the same.

[0115] When the distribution information of call buttons on different floors, the physical parameters of power cables, and / or the number of call buttons in a call group are different, the bus voltage drop generated by the call buttons in the call group on the power cables will be different.

[0116] Step 6033: Configure the communication voltage range for the outgoing callers in each outgoing call group by varying the voltage differences within the operating voltage range of the outgoing callers.

[0117] In this embodiment, the controller can query the operating voltage range (e.g., 24V±20%) of each outgoing caller locally or in the cloud. Within the operating voltage range of each outgoing caller, the controller sequentially traverses each outgoing call group and configures the communication voltage range for the outgoing callers in each outgoing call group at corresponding voltage differences.

[0118] For example, such as Figure 9 As shown, the call buttons in a building are divided into four call groups: call group 1, call group 2, call group 3, and call group 4. The distribution information of the call buttons on each floor, the physical parameters of the power cables, and the number of call buttons in each call group are the same. The bus voltage drop generated by the power cables for the call buttons in each call group is 2V. At this time, the communication voltage range can be configured as [20V, 22V) for call group 1, [22V, 24V) for call group 2, [24V, 26V) for call group 3, and [26V, 28V] for call group 4.

[0119] When the controller adjusts the output voltage of the power cable, it is equivalent to sending a communication request to the caller in a certain call group. When the caller in the call group detects that the voltage value in the power cable is within the communication voltage range configured for it, it connects the communication cable and triggers the communication response.

[0120] Step 604: In the outbound call group mode, verify the original voltage value of the communication voltage range provided to the outbound callers in multiple outbound call groups.

[0121] In the outbound call group mode, the controller can sequentially traverse multiple outbound call groups and verify the original voltage value of the communication voltage range supplied to its outbound call device for each outbound call group. That is, when the voltage supplied by the power cable is the original voltage value, the outbound call device in the outbound call group can detect a voltage value within the communication voltage range in the power cable.

[0122] In one embodiment of the present invention, step 604 may include the following steps:

[0123] Step 6041: In the outbound call grouping mode, determine the outbound call group to be verified as a candidate group.

[0124] In the outbound call grouping mode, each outbound call group can be traversed sequentially, and each outbound call group can be set as an outbound call group to be verified in turn. During the traversal, the outbound call group to be verified is determined as a candidate group.

[0125] Step 6042: When determining the communication cable connection of the outbound caller in the candidate group, query the lower limit voltage value in the communication voltage range configured for the candidate group, and use it as the original voltage value for the initial configuration of the communication voltage range.

[0126] In the outbound call group mode, the controller can control the outbound callers in the candidate group to connect to the communication cable, and the outbound callers outside the candidate group to disconnect from the communication cable. It also polls the status of the outbound callers in the candidate group connecting to the communication cable. When it is determined that all outbound callers in the candidate group are online, the controller can begin configuring the original voltage value for the communication voltage range.

[0127] At this point, the controller can query the lower limit voltage value in the communication voltage range configured for the candidate group, and use it as the initial voltage value for configuring the communication voltage range.

[0128] For example, if the communication voltage range configured for the candidate group is [24V, 26V), then 24V can be used as the initial voltage value for configuring the communication voltage range.

[0129] Step 6043: When powering each caller with the original voltage value through the power cable, receive the measured voltage value detected from the end of the power cable.

[0130] like Figure 10 As shown, a monitoring terminal can be connected to the end of the power cable. When the controller controls the power output to produce the initial original voltage value and supplies power to each caller through the power cable, the controller can receive the voltage value detected by the monitoring terminal from the end of the power cable and record it as the measured voltage value.

[0131] Step 6044: Increase the original voltage value until the measured voltage value reaches the lower limit voltage value in the communication voltage range configured for the candidate group.

[0132] Due to voltage drop caused by line loss in the power cable, the measured voltage value detected at the end of the power cable may be lower than the lower limit voltage value (e.g., 24V) in the communication voltage range configured for the candidate group. In this case, the controller can adjust the power supply to increase the original voltage value of the power supply output. When the measured voltage value detected at the end of the power cable is equal to the lower limit voltage value (e.g., 24V) in the communication voltage range configured for the candidate group, the controller stops increasing the original voltage value of the power supply output.

[0133] At this point, record the original voltage value of the power supply output (e.g., 25.66V) as the original voltage value configured for the communication voltage range corresponding to the candidate group.

[0134] In one embodiment of the present invention, step 604 may further include the following steps:

[0135] Step 6045: Round the original voltage value up to obtain the candidate voltage value.

[0136] In this embodiment, the bit-aligned communication voltage range can be obtained by rounding up the original voltage value after enhancement, and recorded as the candidate voltage value.

[0137] For example, if the original voltage value after the boost is 25.66V, then rounding up 25.66V gives a candidate voltage value of 26V.

[0138] Step 6046: Combine the lower limit voltage value in the communication voltage range configured for the candidate group with the candidate voltage value to form the measurement voltage range.

[0139] Step 6047: If the measured voltage range is the same as the communication voltage range configured for the candidate group, then both the communication voltage range and the improved original voltage value are valid.

[0140] In this embodiment, the lower limit voltage value in the communication voltage range configured in the candidate group can be used as the lower limit value of the measurement voltage range, and the candidate voltage value can be used as the upper limit value of the measurement voltage range. The lower limit voltage value in the communication voltage range configured in the candidate group and the candidate voltage value can be combined to form the measurement voltage range.

[0141] The measured voltage range is compared with the communication voltage range configured for the corresponding candidate group.

[0142] If the measured voltage range is the same as the communication voltage range configured for the corresponding candidate group, it can be determined that both the communication voltage range and the improved original voltage value are valid. At this time, the communication voltage range is written into each caller of the corresponding call group, and the mapping relationship between the communication voltage range of each call group (including callers) and its improved original voltage value is written into the controller.

[0143] If the measured voltage range is different from the communication voltage range configured for the corresponding candidate group, it can be determined that both the communication voltage range and the improved original voltage value are invalid, and the external call grouping mode should be re-executed.

[0144] Step 605: Select the outbound call group to be communicated from the preset multiple outbound call groups as the target group.

[0145] Each outbound call group contains multiple outbound call devices.

[0146] Step 606: Query the communication voltage range configured for the outbound callers in the target group, and use it as the target voltage range.

[0147] Step 607: Query the original voltage value configured for the target voltage range.

[0148] Step 608: Power each caller through the power cable according to the original voltage value, so that the target voltage value received by the caller in the target group is within the target voltage range.

[0149] In this embodiment, the controller can use the call group (identified by information such as ID) as an index to find the original voltage value configured for its target voltage range, and control the power supply to output the original voltage value to the power cable, so that the caller in the target group detects the target voltage value in the power cable within the target voltage range.

[0150] At this time, the caller is used to connect to the communication cable for communication when the target voltage value of the power cable is detected to be within the communication voltage range configured for the current caller.
