[0003] At present, most elevators on the market use terminal control to control the door machine system. When the elevator needs to open the door, the door opening terminal is controlled to output the door opening command. After the door opening input terminal of the door machine system detects the door opening command, the door machine driver controls the door machine motor to perform the door opening action. When the door machine system detects that the door is fully opened, the door machine system sends the door opening signal to the door opening input terminal of the elevator control system through the terminal. When the elevator needs to close the door, the door closing terminal is controlled to output the door closing command. After the door closing input terminal of the door machine system detects the door closing command, the door machine driver controls the door machine motor to perform the door closing action. When the door machine system detects that the door is fully closed, the door machine system sends the door closing signal to the door closing input terminal of the elevator control system through the terminal.

[0036] like Figure 1 As shown, an embodiment of the present invention provides an elevator control device 100. The elevator control device 100 includes an elevator controller 101 and a car top board 102. The elevator controller 101 communicates with the car top board 102 through a first communication mode. The car top board 102 sends data to the door machine device 200 through a first channel and a second channel. The door machine device 200 sends data to the car top board 102 through a third channel and a fourth channel. The elevator controller 101 is used to: determine the working state of the elevator control device 100. When it is determined that the working state of the elevator control device 100 is the target working state, a verification trigger signal is generated, and the car top board 102 is controlled to send the verification trigger signal to the door machine device 200. When the verification state signal returned by the door machine device 200 is received through the car top board 102, an elevator baud rate signal is generated, and the car top board 102 is controlled to send the elevator baud rate signal to the door machine device 200. When the door machine baud rate signal returned by the door machine device 200 is received through the car top board 102, an elevator verification password and a verification random data signal are generated, and the car top board 102 is controlled to send the verification random data signal to the door machine device 200 according to the door machine baud rate signal. When the door machine verification password signal returned by the door machine device 200 is received through the car top board 102, the verification result is determined according to the elevator verification password and the door machine verification password.

[0037] The elevator control device 100 includes an elevator controller 101 and a car top board 102. The elevator controller 101 communicates with the car top board 102 via a first communication method.

[0038] The car top board 102 includes four I / O (input / output) ports, namely YB1, YB2, XB1 and XB2. The door machine device 200 includes four I / O ports, namely XC1, XC2, YC1 and YC2.

[0039] Among them, the car top board 102 sends data to the port XC1 of the door machine device 200 through the port YB1, and the data channel from the port YB1 to the port XC1 is called the first channel. The car top board 102 sends data to the port XC2 of the door machine device 200 through the port YB2, and the data channel from the port YB2 to the port XC2 is called the second channel. The door machine device 200 sends data to the port XB1 of the car top board 102 through the port YC1, and the data channel from the port YC1 to the port XB1 is called the third channel. The door machine device 200 sends data to the port XB2 of the car top board 102 through the port YC2. The data channel from the port YC2 to the port XB2 is called the fourth channel.

[0040] The elevator controller 101 may be a programmable logic controller (PLC), a microcontroller unit (MCU) or a digital signal processing (DSP) controller.

[0041] The elevator controller 101 and the car top board 102 exchange data via a first communication method, wherein the first communication method may be a method of communicating via a communication interface such as RS232 or RS485.

[0042] The elevator controller 101 serves as the brain of the elevator system, aggregates system signals and instructions, and outputs control instructions after comprehensive logical calculations.

[0043] The door machine device 200 may also be called a door machine driver, which is mainly used to drive the elevator door to open and close according to the control command of the elevator control device 100.

[0045] Specifically, the car top board 102 sends the door opening command to the door machine device 200 through the port YB1. After the port XC1 of the door machine device 200 receives the door opening command sent by the port YB1 of the car top board 102, the door machine device 200 controls the elevator to open the door. After the door machine device 200 detects that the door is fully opened, the door machine device 200 controls the port YC1 to output the door opening signal to the XB1 of the car top board 102. The car top board 102 sends the door opening signal to the elevator controller 101 through the first communication method.

[0046] Specifically, the car top board 102 sends the door closing command to the door machine device 200 through port YB2. After port XC2 of the door machine device 200 receives the door closing command sent by port YB2 of the car top board 102, the door machine device 200 controls the elevator door to close. After the door machine device 200 detects that the door is fully closed, the door machine device 200 controls port YC2 to output a door fully closed signal to XB2 of the car top board 102. The car top board 102 sends the door fully closed signal to the elevator controller 101 through the first communication method.

[0048] like Figure 2As shown, the door machine device 200 includes at least one processor 201 and a memory 202, wherein the memory 202 can be built in the door machine device 200 or externally located outside the door machine device 200, and the memory 202 can also be a remotely set memory connected to the door machine device 200 via a network.

[0049] The memory 202, as a non-volatile computer-readable storage medium, can be used to store non-volatile software programs, non-volatile computer executable programs and modules. The memory 202 may include a program storage area and a data storage area, wherein the program storage area may store an operating system, an application required for at least one function; the data storage area may store data created according to the use of the terminal, etc. In addition, the memory 202 may include a high-speed random access memory, and may also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other non-volatile solid-state storage device. In some embodiments, the memory 202 may optionally include a memory remotely arranged relative to the processor 201, and these remote memories may be connected to the terminal via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0052] An embodiment of the present invention provides a verification method for implementing protocol binding between an elevator control device 100 and a door machine device 200.

[0053] See also Figure 3 , Figure 3It is a flowchart of a verification method provided by an embodiment of the present invention.

[0054] The verification method is applied to the elevator control device 100 as described above. The elevator control device 100 sends data to the door machine device 200 through the first channel and the second channel, and the door machine device 200 sends data to the elevator control device 100 through the third channel and the fourth channel. The verification method includes the following steps:

[0055] Step S1, determining the working state of the elevator control device 100.

[0056] Specifically, first, the elevator control device 100 needs to detect its own working state to determine whether the elevator is in a state where the elevator is working normally and no passengers are on board.

[0057] Step S2: When it is determined that the working state of the elevator control device 100 is the target working state, a verification trigger signal is generated and sent to the door machine device 200.

[0058] Specifically, when the elevator control device 100 determines that its working state is the target working state, the elevator control device 100 generates a verification trigger signal, and sends the verification trigger signal to the door machine device 200 through the first channel and the second channel at a fixed baud rate f1. After the door machine device 200 receives the verification trigger signal, the door machine device 200 enters the verification mode and sends the verification status signal to the elevator control device 100 through the third channel and the fourth channel.

[0059] The elevator control device 100 and the door machine device 200 both have a pre-stored fixed baud rate f1, and the fixed baud rate f1 may be 100 bit / s or other appropriate values.

[0060] The target working state refers to the state where the elevator is working normally and no one is on board.

[0061] The elevator control device 100 has a pre-stored verification trigger signal or a method for generating a verification trigger signal. The door machine device 200 has a pre-stored verification status signal or a method for generating a verification status signal.

[0062] The verification trigger signal includes information about the trigger command word, which can be a fixed data, such as 0x0A in hexadecimal or other suitable data. The verification status signal includes information about the response command word, which can be a fixed data, such as 0x0B in hexadecimal or other suitable data.

[0063] In some embodiments, please refer to Figure 4 and Figure 5 , Figure 4 It is a waveform diagram of the verification trigger signal. Figure 5 Schematic diagram of the waveform of the verification status signal. Figure 4 The verification command word in the verification trigger signal is 10100000 in binary, that is, 0x0A in hexadecimal, with the low bit of 0x0A in front and the high bit of 0x0A in the back. Figure 5 The response command word in the check status signal is 10110000 in binary, that is, 0x0B in hexadecimal, with the low bit of 0x0B in front and the high bit of 0x0B in the back.

[0064] In some embodiments, the verification trigger signal includes a first verification trigger signal and a second verification trigger signal. The step of the elevator control device 100 sending the verification trigger signal to the door machine device 200 includes: sending the first verification trigger signal to the door machine device 200 through the first channel, and sending the second verification trigger signal to the door machine device 200 through the second channel. Figure 4 As shown, the first verification trigger signal is the signal corresponding to YB1, and the second verification trigger signal is the signal corresponding to YB2.

[0065] In some embodiments, the verification status signal includes a first verification status signal and a second verification status signal. The door machine device 200 sends the first verification status signal to the elevator control device 100 through the third channel, and at the same time, the door machine device 200 sends the second verification status signal to the elevator control device 100 through the fourth channel. Figure 5 As shown, the first verification state signal is a signal corresponding to YC1, and the second verification state signal is a signal corresponding to YC2.

[0066] Figure 4 and Figure 5 The values ​​of time t1 and time t2 are fixed, and time t1 and time t2 are pre-stored in the elevator control device 100 and the door machine device 200.

[0067] In this embodiment, the elevator control device 100 verifies the trigger signal through Figure 1 The port YB1 and port YB2 in the elevator control device 100 are sent to the door machine device 200. When the elevator control device 100 controls the door machine device 200 normally, the port YB1 and port YB2 will not output at the same time. Therefore, when the port YB1 and port YB2 output high level at the same time and the output time reaches t1, the door machine device 200 detects the signal of port YB2. At this time, the baud rate of the signal output by port YB2 is a fixed baud rate f1. When the signal of port YB1 switches from low level to high level, port YB2 starts to transmit the check command word, such as Figure 4The verification command word sent is shown as a binary number 10100000, that is, 0X0A in hexadecimal, with the low bit of 0X0A in front and the high bit of 0X0A in the back. When the signal of port YB1 switches from a high level to a low level, the sending of the verification command word ends. The door machine device 200 compares the received verification command word with the verification command word pre-stored in the door machine device 200. If the two are consistent, the door machine device 200 switches to the verification mode, and at the same time, the door machine device 200 sends a verification status signal to the elevator control device 100 through port YC1 and port YC2.

[0068] Step S3: When receiving the verification status signal returned by the door machine device 200, an elevator baud rate signal is generated and sent to the door machine device 200.

[0069] Specifically, when the elevator control device 100 receives the verification status signal returned by the door machine device 200 through the third channel and the fourth channel, the elevator control device 100 analyzes the verification status signal to obtain the response command word. The elevator control device 100 compares the response command word of the verification status signal with the response command word pre-stored in the elevator control device 100 to determine whether the door machine device 200 is in the verification mode.

[0070] Then, when it is determined that the door machine device 200 is in the verification mode, the elevator control device 100 generates an elevator baud rate signal and sends the elevator baud rate signal to the door machine device 200 through the first channel and the second channel. After receiving the elevator baud rate signal, the door machine device 200 generates a door machine baud rate signal and sends the door machine baud rate signal to the elevator control device 100 through the third channel and the fourth channel.

[0071] In the embodiment of the present invention, the elevator control device 100 pre-stores an elevator baud rate signal or a method for generating an elevator baud rate signal. The door machine device 200 pre-stores a door machine baud rate signal or a method for generating a door machine baud rate signal.

[0072] The elevator baud rate signal is a signal carrying information of the elevator baud rate f2, and the door machine baud rate signal is a signal carrying information of the door machine baud rate f3.

[0073] In some embodiments, the elevator baud rate f2 may be a fixed data, such as 500 bit / s, 200 bit / s or other suitable data, etc. The door machine baud rate f3 is consistent with the elevator baud rate f2.

[0074] Step S4: When the door machine baud rate signal returned by the door machine device 200 is received, an elevator verification password and a verification random data signal are generated, and the verification random data signal is sent to the door machine device 200 according to the door machine baud rate signal.

[0075] Specifically, when the elevator control device 100 receives the door machine baud rate signal through the third channel and the fourth channel, the elevator control device 100 generates an elevator verification password and a verification random data signal, and sends the verification random data signal to the door machine device 200 at a transmission rate of the door machine baud rate f3. The door machine device 200 generates a door machine verification password signal according to the verification random data signal, and sends the door machine verification password signal to the elevator control device 100 at a transmission rate of the door machine baud rate f3.

[0076] In the embodiment of the present invention, the elevator control device 100 pre-stores a method for generating a random data signal for verification and a method for generating an elevator verification password, and the door machine device 200 pre-stores a method for generating a door machine verification password signal. The random data signal for verification is a signal carrying information of random data for verification, and the door machine verification password signal is a signal carrying information of a door machine verification password.

[0077] Step S5: when receiving the door machine verification password signal returned by the door machine device 200, analyze the door machine verification password signal to obtain the door machine verification password, and determine the verification result according to the elevator verification password and the door machine verification password.

[0078] Specifically, when the elevator control device 100 receives the door machine verification password signal through the third channel and the fourth channel, the elevator control device 100 parses the door machine verification password in the door machine verification password signal, and compares the elevator verification password with the door machine verification password to obtain a verification result. Then, the elevator control device 100 determines whether the door machine device 200 matches the elevator control device 100 according to the verification result. In this way, the data protocol binding between the elevator control device 100 and the door machine device 200 is completed, that is, the verification of the door machine device 200 by the elevator control device 100 is completed.

[0079] See also Figure 6 , Figure 6 It is a flowchart of a method for determining the working state of an elevator control device provided in an embodiment of the present invention.

[0080] Determining the working state of the elevator control device 100 includes the following steps:

[0081] Step S11, obtaining a first random function.

[0082] Specifically, a first random function is pre-stored in the elevator control device 100 .

[0083] The first random function F1(X) may be:

[0084] F1(X)=RAND()*number of runs+current time in minutes+0x1A;

[0085] Among them, RAND() is the RAND() function, which is used to generate uniformly distributed random real numbers greater than or equal to 0 and less than 1. The number of runs is the number of times the RAND() function is run. The current time minute is a number greater than or equal to 0 and less than 60. The hexadecimal number 0x1A converted to decimal is 26.

[0086] Step S12: Calculate the verification time according to the first random function.

[0087] The elevator control device 100 generates the check time by using a first random function.

[0088] The elevator control device 100 first calculates a decimal number including at least a ones digit and a tens digit by using the first random function F1(X).

[0089] The value of the hour of the verification time is the value of the tens digit of the above decimal number, and the value of the minute of the verification time is the value of the units digit of the above decimal number. For example, if the number calculated by the first random function F1(X) is 15286, the units digit of 15286 is 6, and the tens digit of 15286 is 8, then the verification time is 8 hours and 6 minutes.

[0090] Step S13: When the working state of the elevator control device 100 remains in the target working state within the verification time, the working state of the elevator control device 100 is determined to be the target working state.

[0091] The working state of the elevator control device 100 includes a target working state and a non-target working state.

[0092] The target working state means that the elevator controlled by the elevator control device 100 is in an idle state.

[0093] The non-target working state refers to the elevator controlled by the elevator control device 100 being in a non-idle state, that is, other working states except the idle state, such as the state where the elevator is carrying people, the state where the elevator is out of use due to power failure, etc.

[0094] Step S14: When the working state of the elevator control device 100 is a non-target working state within the verification time, determine that the working state of the elevator control device 100 is a non-target working state.

[0095] For example, if the verification time is 8 hours and 6 minutes, if the elevator control device 100 detects that its own working state remains in the target working state within 8 hours and 6 minutes, then the working state of the elevator control device 100 is determined to be the target working state; if the elevator control device 100 detects that its own working state has appeared in a non-target working state within 8 hours and 6 minutes, then the working state of the elevator control device 100 is determined to be a non-target working state.

[0096] See also Figure 7 , Figure 7 The present invention is a flowchart of a method for generating an elevator baud rate signal provided by an embodiment of the present invention.

[0097] In some embodiments, generating an elevator baud rate signal comprises:

[0098] Step S31, obtaining a matching relationship between a second random function and a baud rate.

[0099] Specifically, the elevator control device 100 pre-stores a matching relationship between the second random function and the baud rate.

[0100] The second random function F2(X) may be: F2(X)=RAND()*10. RAND() is a RAND() function, which is used to generate a uniformly distributed random real number greater than or equal to 0 and less than 1.

[0101] Step S32: Calculate a baud rate random number according to a second random function.

[0102] The baud rate random number is the units digit of the decimal number generated by the second random function F2(X), and the baud rate random number is a number greater than or equal to 0 and less than 10.

[0103] Step S33, obtaining the elevator baud rate f2 according to the baud rate random number and the baud rate matching relationship.

[0104] The baud rate matching relationship is shown in the following table:

[0105] Baud rate random number 1 2 3 4 5 6 7 8 9 Elevator baud rate f2 (bit / s) 1000 200 100 66 50 40 30 33 20

[0106] Table 1

[0107] As shown in Table 1 above, the baud rate random number corresponds to the elevator baud rate f2. When the baud rate random number is 1, the corresponding elevator baud rate f2 is 1000bit / s. When the baud rate random number is 2, the corresponding elevator baud rate f2 is 200bit / s. When the baud rate random number is 3, the corresponding elevator baud rate f2 is 100bit / s. When the baud rate random number is 4, the corresponding elevator baud rate f2 is 66bit / s. When the baud rate random number is 5, the corresponding elevator baud rate f2 is 50bit / s. When the baud rate random number is 6, the corresponding elevator baud rate f2 is 40bit / s. When the baud rate random number is 7, the corresponding elevator baud rate f2 is 30bit / s. When the baud rate random number is 8, the corresponding elevator baud rate f2 is 33bit / s. When the baud rate random number is 9, the corresponding elevator baud rate f2 is 20bit / s.

[0108] It should be noted that the above table exemplarily shows the matching relationship between the baud rate random number and the elevator baud rate f2, which can be adaptively modified according to actual needs.

[0109] Step S34, generating an elevator baud rate signal according to the elevator baud rate f2.

[0110] The elevator baud rate signal is a signal carrying information of the elevator baud rate f2.

[0111] Specifically, when the elevator control device 100 determines that its working state is the target working state, the elevator control device 100 first generates a baud rate random number according to the second random function, then obtains the elevator baud rate f2 corresponding to the baud rate random number, then generates an elevator baud rate signal according to the elevator baud rate f2, and finally sends the elevator baud rate signal to the door machine device 200 through the first channel and the second channel. After receiving the elevator baud rate signal, the door machine device 200 analyzes the elevator baud rate signal to obtain the elevator baud rate f2, obtains the door machine baud rate f3 that is the same as the elevator baud rate f2, and generates a door machine baud rate signal. Finally, the door machine device 200 sends the door machine baud rate signal to the elevator control device 100 through the third channel and the fourth channel.

[0112] For details, please refer to Figure 8 and Fig. 9 , Figure 8 It is a waveform diagram of the elevator baud rate signal. Fig. 9 It is a waveform diagram of the door machine baud rate signal.

[0113] In some embodiments, the elevator baud rate signal includes a first elevator baud rate signal and a second elevator baud rate signal. The elevator control device 100 sends the first elevator baud rate signal to the door machine device 200 through the first channel, and the elevator control device 100 sends the second elevator baud rate signal to the door machine device 200 through the second channel.

[0114] In some embodiments, the door machine baud rate signal includes a first door machine baud rate signal and a second door machine baud rate signal. The door machine device 200 sends the first door machine baud rate signal to the elevator control device 100 through the third channel, and the door machine device 200 sends the second door machine baud rate signal to the elevator control device 100 through the fourth channel.

[0115] exist Figure 8 In , the signal corresponding to YB1 is the first elevator baud rate signal, and the signal corresponding to YB2 is the second elevator baud rate signal. Fig. 9 In the example, the signal corresponding to YC1 is the baud rate signal of the first door machine, and the signal corresponding to YC2 is the baud rate signal of the second door machine.

[0116] In this embodiment, the elevator control device 100 transmits the elevator baud rate signal through Figure 1 The port YB1 and port YB2 in the elevator control device 100 are sent to the door machine device 200. When the elevator control device 100 controls the door machine device 200 normally, the port YB1 and port YB2 will not output high level at the same time. Therefore, when the port YB1 and port YB2 output high level at the same time and the output time reaches t1, the door machine device 200 detects the signal of port YB2. At this time, the baud rate of the signal output by port YB2 is a fixed baud rate f1. When the signal of port YB1 switches from low level to high level, port YB2 starts to transmit the elevator baud rate, such as Figure 8 The elevator baud rate sent is 01000000. When the signal of port YB1 switches from high level to low level, the sending of the elevator baud rate ends. The door machine device 200 analyzes the received elevator baud rate signal to obtain the elevator baud rate, and then the door machine device 200 sends the door machine baud rate signal to the elevator control device 100 through port YC1 and port YC2.

[0117] Figure 8 The value of the elevator baud rate f2 in the elevator baud rate signal is 01000000 in binary, which is 64 in decimal, so the elevator baud rate f2 is 64bit / s. Fig. 9 The value of the door machine baud rate f3 in the door machine baud rate signal is 01000000, which is 64 when converted to decimal. Therefore, the door machine baud rate f3 is also 64bit / s.

[0118] See also Fig.10 , Fig.10 The present invention provides a flow chart of generating an elevator verification password and verifying a random data signal in accordance with an embodiment of the present invention.

[0119] In some embodiments, generating an elevator verification password and a verification random data signal includes:

[0120] Step S41, obtaining a third random function and a random data function.

[0121] The random data function F(M) and the third random function F3(X) are pre-stored in the elevator control device 100 and the door machine device 200 .

[0122] The formula of the random data function F(M) can be set as: F(M)=RAND(). RAND() is a RAND() function, which is used to generate a random real number greater than or equal to 0 and less than 1.

[0123] The formula of the third random function F3(M) can be set as: F3(M)=aM+b, wherein a is a fixed constant, b is also a fixed constant, and M is the verification random number data.

[0124] It should be noted that, in addition to the formula of the random data function and the formula of the third random function proposed above, other random data functions and third random functions may be set according to actual needs.

[0125] Step S42: Generate verification random data according to the random data function.

[0126] Specifically, the elevator control device 100 generates the verification random number data M through the random data function F(M).

[0127] Step S43: Generate an elevator verification password according to the third random function and the verification random data.

[0128] Specifically, the elevator control device 100 substitutes the verification random data M into the third random function F3 (M) to obtain the elevator verification password P1.

[0129] Step S44, analyzing the door machine baud rate signal to obtain the door machine baud rate f3.

[0130] Step S45, generating a verification random data signal according to the door machine baud rate f3 and the verification random data.

[0131] Specifically, the elevator control device 100 generates a check random data signal at a transmission rate of the door machine baud rate f3, and then sends the check random data signal to the door machine device 200. After receiving the check random data signal, the door machine device 200 analyzes the check random data signal to obtain the check random data M. Then the door machine device 200 substitutes the check random data M into the pre-stored third random function F3 (M) to obtain the door machine check password P2. The door machine device 200 generates a door machine check password signal according to the door machine check password P2 and the door machine baud rate f3, and sends the door machine check password signal to the elevator control device 100 through the third channel and the fourth channel.

[0132] The check random data signal is a signal carrying information of the check random data M.

[0133] In some embodiments, the check random data signal includes a first check random data signal and a second check random data signal. The elevator control device 100 sends the first check random data signal to the door machine device 200 through the first channel, and at the same time, the elevator control device 100 sends the second check random data signal to the door machine device 200 through the second channel.

[0134] In some embodiments, the door machine verification password signal includes a first door machine verification password signal and a second door machine verification password signal. The door machine device 200 sends the first door machine verification password signal to the elevator control device 100 through the third channel, and at the same time, the door machine device 200 sends the second door machine verification password signal to the elevator control device 100 through the fourth channel.

[0135] It should be noted that the random data signal can be checked by referring to Figure 4 The verification trigger signal in the door machine verification password signal can refer to Figure 5 The calibration status signal in.

[0136] See also Fig.11 , Fig.11 The present invention provides a flowchart of determining a verification result according to an elevator verification password and a door machine verification password.

[0137] In some embodiments, determining the verification result according to the elevator verification password and the door machine verification password includes:

[0138] Step S51, determine whether the elevator verification password and the door machine verification password are consistent.

[0139] Step S52: If the elevator verification password and the door machine verification password are consistent, it is determined that the verification result is that the elevator control device 100 and the door machine device 200 match.

[0140] Step S53: If the elevator verification password and the door machine verification password are inconsistent, it is determined that the verification result is that the elevator control device 100 and the door machine device 200 do not match.

[0141] Specifically, when the elevator control device 100 receives the door machine verification password signal, it will analyze the door machine verification password signal to obtain the door machine verification password P2. The elevator control device 100 compares the door machine verification password P2 with the elevator verification password P1. If the door machine verification password P2 is consistent with the elevator verification password P1, it is determined that the door machine device 200 matches the elevator control device 100. If the door machine verification password P2 is inconsistent with the elevator verification password P1, it is determined that the door machine device 200 does not match the elevator control device.
