[0002] In the prior art, elevator control systems are designed according to relevant national standards or local government requirements (local standards) at the time the elevator is first put into use. Furthermore, the elevator control device is often integrated during design. This results in significant costs associated with replacing the elevator control system for subsequent maintenance and upgrades. Furthermore, the integrated design of the elevator control device within the elevator control system makes existing elevator control systems incompatible with new standards and unable to flexibly meet market demands. For example, after an elevator standard update, it was required to detect the opening and closing of elevator doors to prevent accidents that could injure passengers. However, since the existing elevators' integrated design did not meet the new standards, the entire elevator control system would need to be replaced to meet the new standards and prevent accidents. Another example is when a special case requires the elevator control device within the elevator control system to be customized. This customization requires a complete redesign of the elevator control device, and the existing standard elevator control device cannot meet the requirements of the customized elevator. Consequently, the customized elevator control device suffers from poor compatibility. Summary of the Invention

[0037] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] Example 1

[0039] This embodiment provides an elevator control device, such as Figure 1Shown, including:

[0040] Main controller 1; the main controller 1 is mainly used to receive control signals, process the received control signals, and send the processing results to the slave controller 2 or output them from the functional port of the main controller 1, wherein the main controller 1 may include a control chip and a control circuit.

[0041] At least one slave controller 2; wherein the master controller 1 is connected to the at least one slave controller 2; the slave controller 2 is reserved with a plurality of preset ports 3 for realizing the control function expansion or function upgrade of the target elevator. At least one slave controller 2 is connected to the master controller 1, wherein the master controller 1 has a preset basic elevator function table, and its function table can also be updated and modified by connecting to the preset port 3 of the slave controller 2. For example: when the preset port 3 of the slave controller 2 is connected to a temperature sensor, the sensor transmits the collected signal to the slave controller 2, and the slave controller 2 sends the received signal to the master controller 1. The master controller 1 uses the received data information to query the preset function table for the action information that needs to be controlled to execute the elevator, and outputs the control information through the output port of the slave controller 2 or the original output port of the function port of the master controller 1, and controls the elevator to execute the corresponding action.

[0042] Specifically, the master controller 1 and the slave controller 2 can be connected via a bus, wherein the bus includes a data bus and a control bus. By using the bus to control data between the master controller 1 and the slave controller 2 and the external device, the efficiency and integrity of data transmission can be guaranteed.

[0043] Specifically, the preset ports 3 include: a power supply port, an input port, and an output port. There can be at least two preset ports 3, and their functions can be user-defined. For example, the power supply port can be 24V, and the number of preset ports is four. The output port can also be connected to a relay or switch to perform mechanical actions to control the on / off of the controlled device. The input port can be connected to a button or sensor to collect input signals.

[0044] Optionally, the preset port 3 can be a chip pin or a pad. Preferably, the preset port 3 is a connection terminal. By connecting the terminal of the preset port to the input device or the controlled device using an electrical connection wire, the elevator control system can be upgraded relatively simply and quickly. The connection terminal can be installed on the side of the elevator control device circuit board, which facilitates maintenance personnel to repair and upgrade the elevator control device, facilitates functional expansion, and facilitates the connection of control wires. This allows the elevator control device to be easily and quickly compatible with different elevator standards, and can be flexibly changed to quickly adapt to customer needs.

[0045] Specifically, the elevator control device also includes: a parameter setting panel, which is connected to the main controller and is used to display new elevator functions and set new elevator functions. The parameter setting panel is connected to the main controller 1 and transmits data. By setting the parameters of the parameter setting panel, the main controller 1 receives the set parameters, queries the input parameters, checks the function information corresponding to the preset function table in the main controller 1, and finally connects the preset port and waits for the signal response to realize the addition of the elevator function. It is also possible to first connect the slave controller 2 with an electrical connection line, and then set the parameter setting panel and receive the response waiting for the new function. In addition, it is also possible to invert the original fixed function port or perform logical comparison using the logic device set in the main controller to realize the disabling / adding of the elevator function.

[0046] Specifically, the parameter setting panel includes: a display unit for displaying the newly added function parameters of the elevator that need to be set; the display unit of the parameter setting panel can be a liquid crystal screen or a digital tube.

[0047] The key unit is used to set up new elevator functions. The key unit can be a mechanical key or a touch key.

[0048] Optionally, a slave control chip is provided in the slave controller 2, and the chip can be fixedly connected or detachably connected. A chip holder or chip slot is also provided in the slave controller 2 for installing the slave control chip. When the user needs to upgrade the functions of the elevator system, the functions can be expanded by installing a new slave controller chip in the reserved chip slot / seat. This makes it easier to upgrade the elevator control device, which is beneficial for compatibility with elevator control devices with different requirements. By adding slave control chips and chip slots / seats to achieve functional expansion of the elevator control device, replacing the slave control chip can also save maintenance costs, solving the problem in the prior art of requiring the replacement of the entire elevator control device due to insufficient functional ports of the elevator control device. The slave control chip can be a control chip that has been burned at the factory, and the elevator functions built into the pre-burned control chip can meet the elevator function needs of most users. The user can add / call it through the parameter setting panel. If the pre-programmed function set cannot meet the user's needs, the user can also realize the required new elevator functions by replacing the slave control chip (the slave control chip that realizes the new elevator function needs to be customized by the user from the elevator manufacturer or developed and tested by the user before it can be used, so as to ensure the stability of the subsequent elevator operation).

[0049] Optionally, maintenance personnel can also temporarily burn the slave control chip in the slave controller. When the function information stored in the slave control chip is cleared due to misoperation, maintenance personnel can burn the slave control chip through the preset port of the slave controller, thereby simplifying the maintenance steps and saving maintenance costs when performing elevator control system maintenance.

[0050] Specifically, the main controller 1 is equipped with function ports for implementing pre-installed elevator functions. These ports are defined based on elevator requirements when the elevator leaves the factory, and the corresponding functions are fundamental to elevator operation. The function ports of the main controller 1 also include an analog-to-digital conversion interface, which collects digital signals via a bus and converts them into analog signals, or vice versa, for transmission.

[0051] At least one slave controller is connected to the master controller, and the port of the slave controller connected to the master controller is used as the preset port. When the elevator function upgrade or elevator compatibility setting is required, the corresponding control / controlled device is connected through the preset port, and then the combination upgrade is performed according to the preset function, so that the elevator control device can be compatible with the requirements of different elevator standards and can also flexibly meet market demand.

[0052] Example 2

[0053] This embodiment provides an elevator control method, such as Figure 2 As shown, including:

[0054] S10, obtaining a new function signal; wherein the new function signal is obtained by the user through the parameter setting panel and sent to the main controller; the main controller obtains the new function signal set by the user through the parameter setting panel, and the new function signal can be a coded value that needs to be identified by the main control chip. The identification result corresponds to the function stored in the preset function table of the main controller. For example, when P4C1.40 is set to a specific value, the corresponding functions are stopping at the nearest floor, inhibiting internal calls, inhibiting external calls, and exiting parallel group control. The coded value can be a decimal code value or a hexadecimal code value, and the code value can be defined according to user needs.

[0055] S11, querying the preset function table in the main controller based on the new function signal to obtain function information corresponding to the new function signal; wherein the preset function table is preset by the elevator manufacturer, and the preset function table can also be upgraded online as needed.

[0056] S12: Send the function information to the slave controller, so that the function information is output from the preset port of the slave controller and the target elevator is controlled according to the newly added function. Function information can also be understood as signal response information. The function information set by the master controller is sent to the slave controller. By detecting whether there is a preset port response in the slave controller that meets the corresponding function information, it can be determined whether the set new function needs to be implemented. Upgrading the elevator in this way can ensure that the operating elevator is compatible with the new standard. This method also allows for flexible operation and saves maintenance costs. This solves the problem in the prior art that the integrated design of the elevator controller makes it impossible to upgrade and modify elevator functions and cannot meet existing customer needs for elevators.

[0057] Optionally, the S11 also includes:

[0058] The function ports of the master controller and / or the enabled states of the preset input ports of the slave controller corresponding to the function information in the preset function table are detected according to the preset function table to obtain function information of the corresponding ports; and a logical operation is performed based on the function information of the corresponding ports to determine the function information corresponding to the newly added function signal. The logical operation includes a logical relationship based on any combination of AND, OR, and NOT.

[0059] The main controller obtains a new function signal, wherein the new function signal can be obtained from a parameter setting panel; according to the obtained new function signal, the main controller searches for function information corresponding to the new function signal, and then controls the target elevator according to the function information. Through the above method, it is possible to be compatible with the requirements of different elevator standards and flexibly meet market demand.

[0060] Example 3

[0061] This embodiment provides an elevator control device, such as Figure 3 As shown, the device includes:

[0062] A parameter setting keyboard 4 is connected to the main controller 1 and is used to set the newly added function parameters using the keys provided on the parameter setting keyboard 4. Furthermore, a parameter display is provided on the parameter setting keyboard 4 for displaying the corresponding coded values ​​of the newly added parameters. The display can be an LCD screen or a digital tube display.

[0063] The main controller 1 is mainly used to receive control signals and send action execution signals. In addition, the controller can also perform analog / digital conversion to facilitate data collection.

[0064] Slave controller 2 is used to upgrade the elevator control device and has multiple control ports reserved for connecting input / output devices. These ports can be used to collect signal instructions from input devices and send these instructions to master controller 1 for processing. Master controller 1 then sends output signals to control the target elevator. Optionally, the functional ports of master controller 1 also include input ports and output ports. The elevator input responses received by master controller 1 may include: stopping at the nearest floor, immediate emergency stop, leveling correction, correction to terminal station, door opening request, door closing request, door opening prohibited, door closing prohibited, internal call prohibited, external call prohibited, exiting the parallel group control state, fault reset request, triggering a Class A fault, triggering a Class B fault, triggering a Class C fault, triggering a Class D fault, and other instructions.

[0065] The elevator control function expansion performed by the elevator control device in this embodiment is specifically as follows:

[0066] The user sets the function code value to be added on the parameter setting keyboard 4. The function value is equivalent to the newly added function signal. The code value data corresponds to the coding value of the preset function table preset in the main controller 1, and the corresponding function information can be executed according to the coding value.

[0067] Optionally, when the main controller 1 receives a new function signal set by the parameter setting keyboard 4, the new function signal set at this time is to set the preset function input port, and it is necessary to detect whether there is an input signal at the preset function input port. If there is an input signal in the preset function input port, the new function of the elevator set by the parameter setting keyboard 4 is output through the preset output port of the controller 2. Function information corresponding to the coding value is output, and the elevator executes the new function action according to the function information.

[0068] For example, Figure 4 As shown, when the control parameters set by the parameter setting keyboard 4 are: P4C1.40 = 0x0701 and the corresponding preset function input port IN_01 is valid, the function information corresponding to the code value is output from the preset output port of the controller 2, and the function information is: the running elevator stops at the nearest floor, prohibits internal calls, prohibits external calls, and exits parallel group control are effective at the same time.

[0069] Optionally, the output action of the preset function output port can also be set and controlled by the parameter setting keyboard 4; wherein, a relay or electronic switch is also connected to the preset function output port to realize the control of the newly added output function of the elevator through mechanical action (on / off).

[0070] For example, Figure 5As shown, the control parameters set using the parameter setting keyboard 4 are: P4C1.50 = 0x2280, P4C1.51 = 0, which means that when the elevator is overloaded, the elevator door is opening, and the elevator door is fully opened, the preset function output port OUT_01 is valid, otherwise it is invalid. When the control parameters set on the parameter setting keyboard 4 are P4C1.50 = 0, P4C1.51 = 0x2280, it means that when any of the conditions of elevator overload, elevator door opening, and elevator door fully opened is valid, the preset function output port OUT_01 is valid, otherwise it is invalid. The function information corresponding to the preset function output port can be: elevator class A fault, elevator class B fault, elevator class C fault, elevator class D fault, elevator leveling, elevator normal waiting, elevator normal operation, elevator door opening, elevator door closing, elevator door fully opened, elevator door fully closed, elevator fire status, elevator parking status, elevator overload, elevator maintenance, door opening inching operation, etc.

[0071] Optionally, a simple "AND, OR" logic triggering function is set through the parameter setting keyboard 4 using the function port of the main controller 1 (original input point, original output point, A / D input and D / A output) and the preset port 3 of the slave controller 2, and this new function is used to control the corresponding preset output port of the slave controller 2 to output the function information corresponding to the coding value.

[0072] For example, the control parameters set using parameter setting keyboard 4 are:

[0073] P4C1.60=1290 means using the two function ports IN12 and IN90 of the main controller 1;

[0074] P4C1.61=0105 means using two preset ports NEW_IN01 and NEW_IN05 of slave controller 2;

[0075] Through the logical operation of P4C1.60=1290 and P4C1.61=0105, a new intermediate variable MID_01 is generated. According to any result of this intermediate variable, the function information P4C1.62 corresponding to the code value is output from the preset output port of the controller 2. The function information that can be executed by P4C1.62 can be as follows Figure 6 shown.

[0076] Optionally, new functions are generated through some original elevator states and newly added intermediate variables, where the newly added variables can be set through the parameter setting keyboard 4, and the functional information corresponding to the coding value is output from the preset output port of the controller 2 through the logical operation of "AND, OR, NOT", thereby realizing the new function of the elevator.

[0077] For example, the control parameters set using parameter setting keyboard 4 are:

[0078] P4C1.70=0x0080 means using “elevator door opening” as the first elevator status condition: A;

[0079] P4C1.71=0xFDFF means using the inverse of “elevator door open position” as the second elevator status condition: B;

[0080] P4C1.72=0xBFFF means using the inversion of “elevator maintenance” as the third elevator status condition: C;

[0081] P4C1.73=0x0000 means the fourth elevator status condition is not used;

[0082] P4C1.74=0xFF03 means using the inverse of the intermediate variable MID_03 as the first intermediate variable condition: D;

[0083] P4C1.75=0x0000 means not using the second intermediate variable condition;

[0084] P4C1.76=0x0000 means the third intermediate variable condition is not used;

[0085] P4C1.77=0x0000 means that the fourth intermediate variable condition is not used;

[0086] Among them, the high byte is FF, which means the condition is negated.

[0087] The four conditions A, B, C, and D defined in P4C1.70 to P4C1.77 participate in the operation selected in P4C1.78, and the operation result is output from the preset output port NEW_OUT01 of the slave controller 2. The result of the execution of P4C1.78 is as follows Figure 7 shown.

[0088] Based on the aforementioned optional custom functions, this embodiment allows elevator control by changing the read / write elevator control parameters. The elevator control system can implement corresponding custom expansion functions simply by setting the elevator parameters according to requirements and rules. The elevator master control program selects corresponding variables based on these parameters and performs calculations and control according to specified logical functions. It then outputs the calculation results to intermediate variables, to the preset port 3 of the slave controller 2, and to influence the specified internal state of the elevator.

[0089] Optionally, in order to prevent the customized functions from being modified arbitrarily, after the above customized function test is passed, these parameters need to be protected by password control. That is, a customized function password is set using the parameter setting keyboard 4. Only by using this password can the elevator control device modify the corresponding parameters and change the corresponding customized function, thereby ensuring the safe operation of the elevator control device.

[0090] In this embodiment, the elevator control device's hardware and software cores remain unchanged (no controller replacement is required). Only functional ports and slave controllers are added to the hardware. Simultaneously, the elevator control device's software is expanded, thus not affecting or modifying the elevator's existing functionality. This simply expands upon the original elevator functionality to accommodate elevator standards and user needs that vary over time and location. Furthermore, in this embodiment, the elevator's existing fixed functions are designed to take precedence over all custom functions (for example, if an elevator door is permanently prohibited from opening in a non-leveling area, even if a custom input signal is provided to allow the door to open in a non-leveling area, this will not function). Therefore, the functions of this embodiment further enhance elevator safety on top of the existing basic functions.

[0091] Advantages of this embodiment:

[0092] While retaining existing elevator functions and complying with existing elevator standards, simple expansion of elevator functions can be used to address upgrades or revisions to elevator inspection standards at different times. When using the elevator control device provided by this implementation, even for elevators already in operation, new national, local, and industry standards can be addressed through simple custom function expansion, eliminating the need to replace the elevator control system or allow elevators that do not meet the new standards to continue operating.

[0093] Furthermore, in actual operation, elevator customers usually need to customize some non-standard functions for the elevator. The elevator control device provided in this embodiment can flexibly meet the requirements of elevator customers, thereby saving design costs.

[0094] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention. Such modifications and variations are all within the scope defined by the appended claims.
