[0023] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of an elevator control system 1000 provided in one embodiment of this application.

[0024] This application provides an elevator control system 1000, which includes an outdoor display panel 400, an electrical signal circuit 500, an electrical control circuit 600, a car top control box 700, an in-car operation box 800, a door system 900, a traction machine 200, an encoder 300, and an elevator controller 100.

[0025] The elevator controller 100 is connected to the hall display panel 400, the electrical signal circuit 500, the electrical control circuit 600, the car top control box 700, the traction machine 200, and the encoder 300. The traction machine 200 is also connected to the encoder 300. The car top control box 700 is also connected to the car interior operation box 800 and the door system 900.

[0026] The elevator controller 100 is the "brain" of the elevator, responsible for overall control and coordination of its operation. It receives signals from various components, such as the hall display panel 400 and the electrical signal circuit 500, and then makes decisions based on these signals, sending instructions to components such as the traction machine 200 and the electrical control circuit 600 to achieve functions such as normal elevator operation, door opening and closing, and floor display.

[0027] The hall display panel 400 is installed in the waiting hall on each floor of the elevator to display relevant elevator information to passengers and to obtain passengers' elevator usage needs, such as the current floor of the elevator, the direction of travel (up or down), whether the elevator is under maintenance, and whether passengers have called for an upward or downward elevator.

[0028] The electrical signal circuit 500 is mainly responsible for transmitting various electrical signals, transmitting and converting signals between different components in the elevator control system 1000, and ensuring that the components can communicate and work together accurately. For example, it transmits hall call signals and car instruction signals to the elevator controller 100, and transmits the control signals of the elevator controller 100 to the corresponding execution components.

[0029] The electrical control circuit 600 controls and protects the elevator's electrical equipment. According to the instructions of the elevator controller 100, it controls the starting, stopping, speed adjustment and other operating states of equipment such as traction machine and door operator. It also has overload protection, short circuit protection and other functions to ensure the safe operation of the elevator electrical system.

[0030] The car top control box 700 is installed on the top of the elevator car and is an important component for car-related controls. It receives instructions from the elevator controller 100 and directly controls the in-car operation box 800 and the door system 900, coordinating various operations and functions within the car, such as controlling the opening and closing of the car doors and handling emergency calls within the car.

[0031] The in-car control panel 800 is located inside the elevator car and serves as the interface for passengers to interact with the elevator. It includes buttons for floor selection, door opening, door closing, and emergency call. Passengers use these buttons to issue commands to the elevator control system 1000, such as selecting the desired floor or controlling the opening and closing of the elevator doors.

[0032] The door system 900 includes car doors and landing doors, as well as devices for driving and controlling the opening and closing of the doors. When the elevator arrives at the target floor, the door system automatically opens the car door and the corresponding landing door according to the instructions of the elevator controller 100 to facilitate passenger entry and exit; during elevator operation, the door system ensures that the doors are closed and locked to ensure passenger safety.

[0033] The traction machine 200 is the power unit of the elevator, which drives the car and counterweight to move up and down by driving steel wire ropes. According to the instructions of the elevator controller 100, it realizes the elevator's acceleration, deceleration, leveling and other operating states. Its performance directly affects the elevator's operating speed and comfort.

[0034] The encoder 300 is typically connected to the drive shaft of the traction machine 200 to measure the speed and position of the traction machine 200 in real time and feed this information back to the elevator controller 100. Based on the information fed back by the encoder, the elevator controller 100 precisely controls the elevator's speed and position, achieving accurate leveling and stopping functions.

[0035] Please see Figure 2 , Figure 2 This is a schematic diagram of the structure of an elevator controller 100 provided in one embodiment of this application.

[0036] This application provides an elevator controller 100, which includes a control board 10 and a power board 20. The power board 20 is connected to the control board 10 and is used to connect to a traction machine 200. The power board 20 is used to perform voltage conversion based on the power control signal output by the control board 10 to supply power to the traction machine 200.

[0037] The control board 10 includes a decoding and conversion module 11, a motor control module 12, a data transmission module 13, and a logic control module 14.

[0038] Specifically, the decoding and conversion module 11 is used to connect to the encoder 300, receive the signal from the encoder 300, and decode the signal from the encoder 300 to output a decoded signal.

[0039] The motor control module 12 is connected to the decoding and conversion module 11 and the power board 20 respectively. The motor control module 12 is used to generate a power control signal based on the decoded signal and output the power control signal to the power board 20.

[0040] The data transmission module 13 is used to connect to the car top control box 700, the hall display panel 400, the electrical signal circuit 500, and the electrical control circuit 600, respectively. The data transmission module 13 is used to transmit data with the car top control box 700, the hall display panel 400, the electrical signal circuit 500, and the electrical control circuit 600.

[0041] The logic control module 14 is connected to both the motor control module 12 and the data transmission module 13. The logic control module 14 is used for logic control, including instruction registration, display, door operator control, and signal detection.

[0042] The power control signal is generated by the motor control module 12 based on the decoded signal. It is primarily used to control the power board 20 to perform voltage conversion, thereby achieving precise control over the power supply to the traction machine 200. Specifically, the power control signal, according to the actual needs of elevator operation, such as acceleration, deceleration, and leveling, instructs the power board 20 to convert the input power voltage into appropriate voltage and current values, providing corresponding power to the traction machine 200. This ensures that the traction machine can drive the elevator car and counterweight up and down with accurate speed and force according to the requirements of the elevator control system, guaranteeing the smooth and safe operation of the elevator.

[0043] The decoded signal is the signal output by the decoding and conversion module 11 after decoding the signal received from the encoder 300. The encoder 300 measures the speed, rotation position, and other information of the traction machine 200 in real time and outputs corresponding signals. These signals are usually electrical signals or pulse signals containing specific encoding rules. The decoding and conversion module 11 parses and converts these encoded signals to obtain a decoded signal that can be understood and processed by other modules of the elevator controller 100. Its content mainly reflects the actual operating status of the traction machine 200, such as the current speed, rotation angle, and position. The motor control module 12 generates a corresponding power control signal based on the actual operating status of the traction machine 200 provided by the decoded signal, thereby achieving precise adjustment of the power supply to the traction machine and enabling the elevator to operate accurately according to preset requirements.

[0044] Combination Figure 1 and Figure 2 The working principle of elevator control elevator 100 is briefly explained.

[0045] In practical applications, the decoding and conversion module 11 is used to connect with the encoder 300, receive signals from the encoder 300 that reflect the operating status of the traction machine (such as speed, rotation position, etc.), decode these signals according to specific encoding rules, and output decoded signals that can be recognized by other modules of the elevator controller 100.

[0046] Next, the motor control module 12 acquires the decoding signal output by the decoding and conversion module 11, and generates corresponding power control signals according to the actual operating state of the traction machine 200, such as different situations where the elevator needs to accelerate, decelerate or level, so as to accurately control the operation of the traction machine 200.

[0047] Meanwhile, the power board 20 is connected to the control board 10 and receives the power control signal output by the motor control module 12. Based on the signal, it transforms the input power supply voltage and adjusts it to a voltage and current suitable for the operation of the traction machine 200, so as to provide power for the traction machine 200 and drive the elevator car and counterweight to move up and down.

[0048] Furthermore, the data transmission module 13 is responsible for data interaction with the car top control box 700, the hall display panel 400, the electrical signal circuit 500, and the electrical control circuit 600 to realize information transmission between various parts of the elevator. The logic control module 14 coordinates the motor control module 12 and the data transmission module 13 to control the overall operation process of the elevator according to the logical requirements of elevator operation, such as floor calls and safety signals.

[0049] The elevator controller 100 provided in this application embodiment reduces the elevator control circuit board from the traditional four circuit boards (one logic control board, one motor control board, one PG card, and one power board) to two circuit boards (control board 10 and power board 20), improving production efficiency, maintainability, and reducing costs. The communication between logic control and drive control is changed from between circuit boards (the logic control board, motor control board, and PG card) to within the circuit board itself. Figure 2 The communication within the control board 10 greatly enhances the communication anti-interference capability.

[0050] Please see Figure 3 , Figure 3 This is a schematic diagram of the structure of the control board 10 provided in one embodiment of this application.

[0051] In some embodiments, the decoding and conversion module 11 includes a decoding chip 111. The decoding chip 111 is connected to the motor control module 12, and is used to connect to the encoder 300. The decoding chip 111 is used to receive signals from the encoder 300 and decode the signals from the encoder 300 to output a decoded signal.

[0052] The decoding chip 111 can be an FPGA (Field Programmable Gate Array) or any other device capable of receiving signals from the encoder 300 and decoding the signals from the encoder 300 to output a decoded signal.

[0053] As an example, the decoding chip 111 is an FPGA. The circuitry within the decoding chip 111 for PG decoding (PG decoding is a process of processing and decoding encoder signals to extract useful information for controlling external devices or acquiring data) includes a signal receiving circuit, a filtering circuit, and a signal processing circuit. The signal receiving circuit receives the encoder signal. The filtering circuit filters the signal. The signal processing circuit primarily performs signal conversion from the encoder, such as converting analog signals to digital signals and performing subdivision. The converted decoded signal is then sent to the motor control module 12 for motor control.

[0054] Furthermore, since the decoding circuit is built using the decoding chip 111 (which can be an FPGA), the signal filtering time and filtering method can be realized by setting system parameters (the system parameters are adjustable), which greatly improves the anti-interference performance of the elevator integrated controller and enhances its adaptability to field applications.

[0055] In some embodiments, the motor control module 12 includes a current and voltage detection unit 121, a motor main control chip 122, and a waveform output unit 123. Specifically, the current and voltage detection unit 121 is connected to the traction machine 200 and is used to detect the current and voltage of the traction machine 200 to obtain current and voltage signals. The motor main control chip 122 is connected to both the current and voltage detection unit 121 and the decoding and conversion module 11, and is used to output a waveform control signal based on the decoded signal, the current signal, and the voltage signal. The waveform output unit 123 is connected to both the motor main control chip 122 and the power board 20, and is used to output a power control signal based on the waveform control signal.

[0056] The current signal is an electrical signal that reflects the magnitude and changes of the current during the operation of the traction machine 200 in real time. It embodies information such as the intensity and direction of the current during the operation of the traction machine 200 in the form of an electrical signal, and is one of the important bases for the motor main control chip to judge the working status of the traction machine and perform control.

[0057] The voltage signal is an electrical signal used to represent the magnitude and changes of the voltage that the traction machine 200 withstands during operation. It reflects the power supply voltage status of the traction machine. By analyzing the voltage signal, the motor main control chip can understand the power supply status of the traction machine and make corresponding control decisions.

[0058] The waveform control signal is generated by the motor main control chip 122 after comprehensive analysis of the decoded signal, current signal, and voltage signal. It is mainly used to control the waveform output unit to output a specific waveform, which determines the frequency, duty cycle, and other parameters of the output signal, so as to achieve precise control of the traction machine 200.

[0059] The power control signal, generated by the waveform output unit 123 based on the waveform control signal, directly acts on the power board 20, thereby controlling the power output of the traction machine 200. It can adjust the output power of the traction machine 200, enabling the traction machine 200 to provide appropriate power according to actual needs.

[0060] The current and voltage detection unit 121 can be an ADC (Analog-to-Digital Converter) or any other suitable device, used to implement current and voltage detection.

[0061] The motor control chip 122 can be a DSP (Digital Signal Processor) or any other suitable device.

[0064] Logic control includes registration of internal and external call commands, display inside the car and outside the hall, door opening and closing control, signal detection, etc.

[0065] The logic control chip 141 can be an MCU (Micro Controller Unit) or any other suitable device.

[0066] In some embodiments, the data transmission module 13 includes an I / O input unit 131 and an I / O output unit 132. Specifically, the I / O input unit 131 is connected to the logic control module 14 and is used to connect to the electrical signal circuit 500. The I / O input unit 131 is used to transmit data between the logic control module 14 and the electrical signal circuit 500 to receive elevator shaft and peripheral electrical signals. The I / O output unit 132 is also connected to the logic control module 14 and is used to connect to the electrical control circuit 600. The I / O output unit 132 is used to transmit data between the logic control module 14 and the electrical control circuit 600 to output control signals for peripheral electrical components.

[0067] The I / O input unit 131 is primarily responsible for data transmission between the logic control module 14 and the electrical signal circuit 500. Its core function is to receive electrical signals from the elevator shaft and surrounding equipment. Specifically, the I / O input unit 131 can acquire various electrical signals generated by the elevator shaft and surrounding equipment, which may include elevator car position signals, door open / close status signals, safety device trigger signals, etc.

[0068] The IO output unit 132 is mainly responsible for data transmission between the logic control module 14 and the electrical control circuit 600, and its function is to output control signals for peripheral electrical components. Specifically, the IO output unit 132 receives control commands and data from the logic control module 14 and converts them into control signals suitable for driving peripheral electrical components. These signals may include motor drive signals, relay control signals, indicator light control signals, etc., to achieve control of peripheral electrical components such as elevator door operators, traction machines, and floor indicator lights.

[0069] In some embodiments, the data transmission module 13 further includes an RS485 communication unit 133, a 232 communication unit 134, and a CAN communication unit 135.

[0070] Specifically, RS485 communication unit 133 is connected to logic control module 14 and is used to connect to hall display panel 400 for data transmission between logic control module 14 and hall display panel 400. RS485 communication unit 134 is connected to logic control module 14 for data monitoring. CAN communication unit 135 is connected to logic control module 14 and is used to connect to car top control box 700 for data transmission with car top control box 700.

[0071] In some embodiments, the elevator controller 100 further includes an interaction module 15. Specifically, the interaction module 15 is connected to the logic control module 14, and the interaction module 15 is used for human-computer interaction.

[0072] The interaction module 15 can be a keyboard or any other suitable device.

[0073] In some embodiments, the elevator controller 100 further includes a clock module 16. Specifically, the clock module 16 is connected to the logic control module 14, and the clock module 16 is used to provide real-time time and record timestamps.

[0074] The clock module 16 can be an RTC (Real-Time Clock) or any other suitable device. The clock module 16 provides real-time time and records timestamps, and can also synchronize the clocks of various nodes to ensure the accuracy of data transmission and processing in the system, guaranteeing data consistency and reliability.

[0075] In some embodiments, the elevator controller 100 further includes a storage module 17. Specifically, the storage module 17 is connected to the logic control module 14 and is used for data storage.

[0076] The storage module 17 can be an EEPROM (Electrically Erasable Programmable Read-Only Memory) or any other suitable device. It is used to store information (or data) such as parameter settings, operation records, and fault codes of the elevator controller 100, ensuring that the equipment can retain important data and maintain normal operation after power failure or restart.

[0077] The elevator controller 100 integrates logic control, drive control, and encoder decoding onto a single circuit board (control board 10). It uses a decoding chip 111 (which can be an FPGA) to perform decoding control, achieving a single physical interface and enabling decoding of all types of encoders. Furthermore, it reduces the number of elevator control circuit boards from the traditional four (one logic control board, one motor control board, one PG card, and one power board) to two (control board 10 and power board 20), improving production efficiency, maintainability, and reducing costs. The communication between logic control and drive control is changed from inter-circuit communication (between the logic control board, motor control board, and PG card) to communication within the circuit board itself. Figure 2The communication within the control board 10 significantly improves the communication anti-interference capability. Furthermore, by using a decoding chip 111 (which can be an FPGA) to build the decoding circuit, the signal filtering time and filtering method can be implemented by setting system parameters, greatly improving the anti-interference performance of the elevator integrated controller and enhancing its adaptability to field applications.

[0078] In summary, the elevator controller 100 provided in this application embodiment can decode signals from different types of encoders, avoiding the complexity of configuring different decoding cards for different encoders and improving system compatibility. By tightly integrating the control board and power board, interference problems caused by too many communication links are reduced. Furthermore, since the decoding and processing of encoder signals are completed internally on the control board, compared to hardware decoding cards with fixed filtering parameters, it may be more advantageous for optimizing the signal processing and coping with different interference environments.
