[0065] In order to make the above-mentioned purposes, features and advantages of the application more obvious and easy to understand, the application will be further described in detail below with reference to the drawings and specific embodiments.

[0066] Referring to Figure 1 , a step flow chart of the adaptive communication method provided by the embodiment of the application is shown, which can specifically include the following steps:

[0067] Step 101, the master device control system identifies the current running state of the elevator;

[0068] Step 102, the communication control information of each slave device is determined according to the current running state of the elevator; the communication control information includes communication period or silence demand mark information;

[0069] Step 103, the communication control information of each slave device is sent to the slave device;

[0070] Step 104, each slave device performs communication control processing on the device according to the respective communication control information.

[0071] The adaptive communication method of the application can be applied to the devices on the elevator communication bus, which include the master device control system and the slave devices, referring to Figure 2 On the CANBUS bus of the elevator, the absolute position detection device, the communication type door system, the car roof box, the car button plate, the car display plate and other communication type devices are respectively configured, and the above-mentioned communication devices are mounted on the same bus as the control system. Among them, the control system is the master device, and the remaining bus devices are the slave devices.

[0072] In the embodiment of the application, the current running state of the elevator is first accurately identified by the master device control system. The control system can monitor the position, speed, up and down, stop, door opening and closing and other state information of the elevator in real time through the integrated sensor network and the state monitoring module, accurately master the real-time running condition of the elevator, and ensure that the subsequent communication scheduling strategy can accurately dock the actual working condition of the elevator.

[0073] After determining the current running state of the elevator, the master device control system can further analyze the information and determine the communication control information of each slave device according to the analysis result. The communication control information of each slave device can include a communication period and a silence demand mark information. The communication period indicates the frequency of adjusting data transmission, and the silence demand mark information indicates that some unnecessary devices temporarily stop sending data to save resources. For example, when the elevator is running fast or emergency braking, some slave devices may need more frequent communication, while some devices may temporarily not need communication. In this way, the system can flexibly adjust the communication period according to the actual needs of different devices to ensure the timely delivery of important information.

[0074] After determining the communication control information of each slave device, the master device control system sends the information to the slave devices to ensure the rapid and accurate transmission of information and provide protection for the real-time communication of the elevator system.

[0075] After the slave device receives the communication control information, the slave device will perform communication control processing on the device according to the information, including sending and receiving data according to the communication period, and entering a silent state when needed. Through this flexible control method, the slave device can adjust its communication behavior according to the actual needs to avoid occupying bus resources in unnecessary situations. At the same time, this real-time control also ensures the safety and stability of the elevator system, improves the comfort and safety of the elevator.

[0076] In an embodiment of the present application, the communication control information of each slave device is determined according to the current running state of the elevator, including:

[0077] determining the communication risk level of each slave device according to the current running state of the elevator;

[0078] determining the communication control information of each slave device according to the communication risk level of each slave device.

[0079] The master control system, after identifying the current operating state of the elevator, also evaluates the communication risk levels of the slave devices according to the state information, and formulates the communication control information of the slave devices accordingly. Specifically, first, the master control system can evaluate the communication risk level of each slave device at a specific time based on the operating state information. The communication risk level reflects the importance of the communication function of the slave device to the overall safety of the elevator operation and the risk of communication interference or failure that the slave device may face under the current operating state of the elevator. For example, the absolute position detection device of the elevator and the communication type door system, when the elevator is running at high speed or is about to stop, their communication risk level will be evaluated as high, because they need to transmit critical information in real time and accurately to ensure the safe operation of the elevator. On the contrary, some slave devices for displaying floor information or playing music, when the elevator is running normally, their communication risk level may be relatively low.

[0080] After determining the communication risk levels of the slave devices, the master control system formulates the communication control information of the slave devices according to the level information. For slave devices with a high current communication risk level, the system assigns a higher communication priority, shortens their communication cycle, and ensures the timely transmission of critical information. For slave devices with a low current communication risk level, the system may appropriately extend their communication cycle or put them in a silent state when necessary, to save bus resources and avoid unnecessary communication interference.

[0081] Through this method of determining the communication risk level of the slave device based on the operating state of the elevator and then formulating the communication control information, the application can realize flexible allocation and efficient use of the elevator communication bus resources, ensuring the safe operation of the elevator and improving the passenger experience.

[0082] In an embodiment of the application, determining the communication risk level of each slave device according to the current operating state of the elevator comprises:

[0083] determining the communication risk level of each slave device according to the preset first correspondence relationship and the current operating state of the elevator; the preset first correspondence relationship is the correspondence relationship between various operating states of the elevator and the communication risk level of the device;

[0084] determining the communication control information of each slave device according to the communication risk level of each slave device, comprising:

[0085] if the communication risk level of all slave devices is lower than high risk, determining the communication cycle of each slave device according to the preset second correspondence relationship and the communication risk level of each slave device; the preset second correspondence relationship is the correspondence relationship between the communication risk level of the device and the communication cycle of the device;

[0086] If the communication risk level of a slave device is high risk, the communication control information of other slave devices except the slave device with the high risk level is determined as the silence demand mark information, and the communication period of the slave device with the high risk level is determined according to the preset second corresponding relationship and the communication risk level of the slave device with the high risk level.

[0087] For each slave device on the communication bus, the control system determines the communication risk level of each slave device according to the running state of the elevator, specifically: first, the master device control system will determine the communication risk level of each slave device according to the preset first corresponding relationship, i.e., the corresponding relationship between various running states of the elevator and the device communication risk level, combined with the current running state of the elevator. Among them, the corresponding relationship between various running states of the elevator and the device communication risk level can be obtained based on a large amount of actual running data analysis, which can more accurately reflect the change trend of the communication risk of each slave device under different running states.

[0088] Next, according to the determined communication risk level of each slave device, the master device control system will further determine the communication control information of each slave device. If the communication risk level of all slave devices is lower than high risk, then the control system will determine the communication period of each slave device according to the preset second corresponding relationship, i.e., the corresponding relationship between the device communication risk level and the device communication period. Among them, the corresponding relationship between the device communication risk level and the device communication period is also obtained based on actual running data analysis, which can ensure that each slave device can transmit data according to a reasonable communication period under a lower risk level, and when some slave devices are in a medium risk level, the bus resources can be used preferentially, which not only ensures the normal operation of the elevator, but also avoids waste of resources.

[0089] Further, if the communication risk level of a slave device is evaluated as high risk, then in this case, the master device control system will first determine the communication control information of other slave devices except the slave device with the high risk level as the silence demand mark information. This means that these non-high-risk slave devices will be temporarily placed in a silent state and will no longer send data to release bus resources. At the same time, the system will determine the communication period of the slave device with the high risk level according to the preset second corresponding relationship. Such a design can ensure that critical information can be transmitted in time and preferentially in an emergency, thereby ensuring the safe operation of the elevator.

[0090] The method of the embodiment of the application is applicable to all devices on the communication bus, and different slave devices can be flexibly controlled. Specifically, the corresponding communication abnormal risk degree of each slave device under different elevator running states and the corresponding communication period can be determined in advance for each slave device.

[0091] For the absolute position detection device, the communication risk level is mainly affected by the running speed and the running position, and different communication risk areas and communication risk speeds correspond to different communication risk levels. Generally, the position of the elevator close to the upper and lower terminal stations is a high-risk area, and there is a risk of lucky top squatting bottom after position abnormality in this area. The position of the elevator at the intermediate floor is a low-risk area, and position abnormality in the low-risk area mostly causes large deviation of elevator landing progress, and the comfort of elevator stopping process is general, but does not affect the safety of elevator boarding. Low-speed running is a medium-risk speed, prohibition is a low-risk speed, and high-speed running is a high-risk speed.

[0092] For the communication type door control system, the system operation is less affected by communication when the elevator is stationary, which is low risk; the door system needs to remain closed during running, and the door system state does not need to be changed, which is medium risk; communication interruption during opening and closing operations will cause opening and closing abnormalities, which is high risk; special conditions during opening and closing operations will cause opening and closing emergency stop, such as light curtain action during closing, which requires immediate stop of the closing action, so it is classified as extra-high risk, etc. Accordingly, the communication period is T when the risk is high, the communication period is 2T when the risk is medium, the communication period is 3T when the risk is low, and the silent demand flag is triggered when the risk is extra-high. Among them, T can be a constant for different elevator systems, and on this basis, the communication period T of high risk and the communication periods of low risk and medium risk can be adjusted according to the actual elevator situation, which can be accelerated and slowed down.

[0093] For devices such as car roof boxes and car button plates that input and output signals, the risk can be determined by whether the signal changes when the elevator running state changes, and the signal whether it will affect the passenger boarding experience is used as an auxiliary basis, such as signal changes affecting passenger boarding experience being classified as high risk, signal changes not affecting passenger boarding experience being classified as medium risk, and signal not changing being classified as low risk; for display devices such as car display panels, the running floor changes during running are high risk, other running is medium risk, and stopping running is low risk. Accordingly, like the communication type door system, the communication period is T when the risk is high, the communication period is 2T when the risk is medium, and the communication period is 3T when the risk is low.

[0094] After the communication abnormality risk degree and the corresponding communication period of each slave device in different elevator running states are determined in advance, the communication period can be calculated according to the real-time running state of the elevator and the communication control can be adjusted in real time.

[0095] In an embodiment of the present application, the slave device includes an absolute position detection device,

[0096] The communication risk level of each slave device is determined according to the current running state of the elevator, including:

[0097] determining a speed risk level of the absolute position detection device according to the preset third corresponding relationship and the current running speed; the preset third corresponding relationship is a corresponding relationship between various running speeds of the elevator and the speed risk level;

[0098] determining a position risk level of the absolute position detection device according to the preset fourth corresponding relationship and the current running position; the preset fourth corresponding relationship is a corresponding relationship between various running positions of the elevator and the position risk level;

[0099] determining the communication control information of each slave device according to the communication risk level of each slave device, comprising:

[0100] determining the communication period of the absolute position detection device according to the preset fifth corresponding relationship and the speed risk level and the position risk level of the absolute position detection device; the preset fifth corresponding relationship is a corresponding relationship between the speed risk level, the position risk level and the communication period of the absolute position detection device.

[0101] The absolute position detection device on the communication bus can use the currently commonly used ELA30N-101AN30Y3 grating ruler of the optical detection method or the LIMAX33CP-00 magnetic grating ruler of the magnetic detection method, and includes but is not limited to the above-mentioned devices. The absolute position detection device is installed in the shaft, detects the current absolute position of the car through the magnetic detection or optical detection method, cooperates with the relative position collected by the rotary encoder device installed on the three-phase motor to perform a position correction function, avoids the abnormal position of the car caused by mechanical slip during the running of the elevator, and improves the safety of the elevator. After the position deviation caused by slip during the high-speed running of the elevator, the control accuracy of the elevator is affected, the comfort of the elevator is affected, and the car may be crashed or squat at the end of the position anomaly, which affects the safety of the passengers in the car. Therefore, the real-time requirement of the absolute position detection device is the highest, and the absolute position is ensured not to be interrupted during the running process, which affects the safety of the elevator. The current general scheme mainly accelerates the communication period of the absolute position detection device to improve the communication real-time performance, and the system triggers a fault stop of the elevator after detecting a communication packet loss, thereby ensuring the safety of the passengers in the car. However, this also causes the elevator to be easily triggered to stop due to a communication packet loss in a poor communication quality site. According to the characteristics of the absolute position detection device, the communication quality of the absolute position detection device can be greatly optimized through this embodiment of the application, and the phenomenon of frequent triggering of a fault stop of the elevator in a poor communication quality site is solved.

[0102] The control system formulates different communication quality diagnosis mechanisms according to the current state, appropriately reduces the communication quality diagnosis priority when the elevator stops running, and relaxes the detection threshold of the communication abnormality judgment to avoid communication failure in the stop state. The running state recognized by the control system can include the current running speed and the current running position. During running, the current running speed received through the last communication and the current running speed fed back by the encoder signal are combined to judge the running speed classification and the position classification of the current elevator.

[0103] Specifically, the control system can determine the speed risk level of the absolute position detection device according to a preset third correspondence relationship, i.e., the correspondence relationship between various running speeds of the elevator and the speed risk level, and in combination with the current running speed. The correspondence relationship between various running speeds of the elevator and the speed risk level can be obtained based on a large amount of actual running data analysis and can more accurately reflect the change trend of the communication risk of each slave device under different running speeds. The control system can determine the position risk level of the absolute position detection device according to a preset fourth correspondence relationship, i.e., the correspondence relationship between various running positions of the elevator and the position risk level, and in combination with the current running position. The correspondence relationship between various running positions of the elevator and the position risk level can be obtained based on a large amount of actual running data analysis and can more accurately reflect the change trend of the communication risk of each slave device under different running positions.

[0104] Next, the control system determines the communication period of the absolute position detection device according to a preset fifth correspondence relationship, i.e., the correspondence relationship between the speed risk level, the position risk level, and the communication period of the absolute position detection device, and in combination with the speed risk level and the position risk level of the absolute position detection device. The correspondence relationship between the speed risk level, the position risk level, and the communication period of the absolute position detection device can be obtained based on a large amount of actual running data analysis and can more accurately reflect the change trend of the communication risk of each slave device under different running speeds and different running positions.

[0105] Specifically, different communication detection thresholds and communication period planning are divided according to the current position risk level and the speed risk level, i.e., the current risk area and the risk speed. When running at a low risk area and a medium speed, the detection threshold of the communication abnormality judgment can be appropriately relaxed, and the communication period of the communication can be reduced. When running at a high risk area and a high risk speed, the detection threshold of the communication abnormality judgment can be increased, and the communication period of the communication can be accelerated.

[0106] In an embodiment of the present application, the communication period of the absolute position detection device is a preset multiple of the communication abnormality detection threshold; the method further comprises:

[0107] The maximum packet loss time after continuous packet loss at the current running speed affects the safety control of the elevator, and the maximum packet loss time is the communication anomaly detection threshold.

[0108] In the embodiment of the application, the basic communication period of the absolute position detection device and other slave devices can be different because the absolute position detection device is related to the running speed and the running position. The basic communication period, i.e., the communication anomaly detection threshold, can be calculated according to the running speed and the running position, and the current communication period can be calculated according to the communication anomaly detection threshold to speed up or slow down. The communication anomaly detection threshold is the maximum packet loss time after continuous packet loss at the current running speed, which affects the safety control of the elevator. Therefore, the communication anomaly detection threshold can be obtained by calculating the maximum packet loss time after continuous packet loss at the current running speed, which affects the safety control of the elevator.

[0109] Specifically,

[0110] L1 is the current position of the last correct data packet record;

[0111] V1 is the current speed of the current encoder signal feedback;

[0112] L2 is the farthest position in the current running direction, which is obtained by shaft self-learning before the first running of the elevator, and the shaft self-learning method is a general method in the industry;

[0113] L3 is the displacement required for special deceleration at the current speed;

[0114] A1 is a special deceleration parameter, and the default value is 0.9 m / s 2 ;

[0115] T1 is the maximum packet loss time;

[0116] C1 is a maximum packet loss time parameter, and the default value is 0.7, which can be freely set and ranges from 0.2 to 1.

[0117] The calculation formula is as follows:

[0118] L3 = V1 2 / (2*A1)

[0119] T1 = ((L2-L1-L3) / V1)*C1

[0120] The general communication period is T1 / 3, and the communication anomaly detection threshold is T1.

[0121] If the current communication interruption time is greater than (2 / 3*T1), the system triggers a silent demand marker.

[0122] In one embodiment of the application, each slave device performs communication control processing on the device according to the respective communication control information, including:

[0123] If the communication control information of the slave device is the silence demand mark information, the slave device controls the device to enter a silence state; the silence state is a one-way receiving data mode;

[0124] If the communication control information of the slave device is a communication period, the slave device controls the device to communicate according to the communication period.

[0125] In the embodiment of the application, the master device control system determines the communication control information of each slave device, specifically, actively sends a heartbeat packet, the slave device receives the heartbeat packet of the master device, and obtains the communication control information and state information from the heartbeat packet.

[0126] The heartbeat packet sent by the master device contains the communication control information, which mainly includes the communication period of each slave device and the silence state of each slave device; meanwhile, the running state information of the elevator is also contained, including but not limited to the position, speed, up-down, stop, door opening and closing state information of the elevator.

[0127] After the slave device receives the heartbeat packet of the master device, the running state information of the elevator is parsed to do the basic function processing of the device, for example, the current floor is displayed on the display through the information to do the floor display, the running direction information of the elevator is displayed by parsing the running state of the elevator. The communication control information is parsed to do the communication control processing, if the communication control information of the slave device is the communication period, the slave device controls the device to communicate according to the communication period, which is used as the sending beat control of the device on the bus.
