detailed description

The present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

As shown in Figure 1, it is a structural schematic diagram of an embodiment of an elevator calling device of the present invention, including: at least two elevator buttons (for example, 110 in Figure 1), a controller 120, a control line 130, and a serial communication bus 140, all of which Described elevator button (for example, 110 among Fig. 1) comprises button control module (for example, 111 among Fig. 1), logic control circuit (for example, 112 among Fig. 1);

The controller 120 and each elevator button (for example, 110 in FIG. 1 ) are sequentially connected in series through the control line 130, and connected end to end, and the button control modules (for example, 111 in FIG. 1 ) are respectively connected through the serial The communication bus 140 is connected to the controller 120;

The button control module and the logic control circuit are respectively connected to the control line inlet terminal (for example, 131 in Fig. 1), the button control module is connected to the logic control circuit, and the logic control circuit is connected to the control line outlet ( For example, 132 in Fig. 1);

The controller 120 sends identification information to the button control module of each elevator button through the serial communication bus 140, and sends the start signal to the adjacent control line inlet terminal 131;

The button control module is used to set the logo when receiving the startup signal and the logo information; the logic control circuit is used to send the startup signal to the outlet of the control line when the logo of the elevator button is successfully set.

Wherein, in Fig. 1, only the label of the first elevator button is marked, and because the other elevator buttons are the same as the first elevator button, they are not marked. The elevator buttons referred to in this embodiment are the elevator buttons in series. The first elevator button is adjacent to the controller, and the button control module and the logic control circuit are both connected to the controller. The end-to-end connection is the connection between the last elevator button and the controller. The controller can be a car controller or a control box control board.

The incoming and outgoing ends of the control line are for the elevator buttons, whether the controller and the elevator buttons are connected through control lines, or the elevator buttons and elevator buttons are connected through control lines, one of the input ends of the elevator buttons is connected to the control line incoming line One of the output ports of the elevator button is connected to the outlet of the control line. For the first elevator button, 131 is the incoming end of the control line, and 132 is the outgoing end of the control line. For the second elevator button, 133 is the incoming end of the control line, and 134 is the outgoing end of the control line.

Each elevator button is connected to its own control line incoming terminal and control line outgoing terminal. For example, the button control module 111 and the logic control circuit 112 of the first elevator button 110 are respectively connected to the control line inlet terminal 131, the button control module 111 is connected to the logic control circuit 112, and the logic control circuit 112 is connected to the control line outlet terminal 132.

The controller sends the start signal to the adjacent control line inlet end 131, that is, sends the start signal to the button control module and logic control circuit of the first elevator button.

The button control module sends a start signal to the logic control circuit when the identification is set successfully, and the logic control circuit sends a start signal to the control line outlet according to the start signal transmitted by the control line terminal and the start signal sent by the button control module.

In the elevator calling device of this embodiment, since the controller and the elevator buttons are connected in series through the control wires in turn, and connected end to end, the button control modules are respectively connected to the controller through the serial communication bus; the button control modules and the logic control circuits are respectively connected to the control wires On the incoming line end, the button control module is connected to the logic control circuit, and the logic control circuit is connected to the outgoing line end of the control line. Therefore, the controller can send the identification information to the button control module of each elevator button, and each elevator button can be controlled by the logic control circuit to sequentially set the identification information until the initialization of the elevator buttons is completed. Therefore, it can not only solve the complicated wiring of high floors, but also save costs. And by connecting the last elevator button with the controller through the end-to-end connection, it is easy to judge whether the initialization is completed or not.

In one of the embodiments, an initialization process of an elevator calling device is disclosed.

The controller sends identification information to the button control module of each elevator button through the serial communication bus, and sends the start signal to the adjacent control line inlet end (that is, the start signal is sent to the button control module and logic control module of the first elevator button). circuit); when the controller receives the write success information by the serial communication bus, it sends the next identification information to the button control module of each elevator button, wherein each identification information is different; the identification information can be ID information, physical address information The purpose is to distinguish different elevator buttons, so different elevator buttons are set with different identification information.

When the button control module receives the identification information, it judges whether the start signal is received through the control line inlet end, if received, it judges whether the identification is successful, if the identification is unsuccessful, then the identification is set according to the identification information, and the control signal is sent to the control The logic control circuit sends a start signal to the button control module and the logic control circuit of the next elevator button through the outlet end of the control line, wherein the logic control circuit of the last elevator button sends a start signal to the elevator button through the outlet end of the control line The controller sends a start signal; if the mark is successful or the start signal is not received, the mark setting will not be performed;

Initialization is complete when the controller receives a start signal.

In this embodiment, since the last elevator button is connected to the controller, the controller can judge whether the initialization is completed by whether the start signal is received.

When the sent identification information is ID information, the controller controls the tag information sent each time to be information obtained by adding 1 to the tag information sent last time, wherein the tag information sent for the first time is 1. In this way, when the initialization is completed, you can know how many elevator buttons there are, so as to avoid the user's subsequent detection of the number of buttons.

In one of the embodiments, each of the elevator buttons further includes an input module and an output module, and the input module and the output module are respectively connected to the button control module;

Output module for lift buttons for:

When the button control module of the elevator button is detected to send a write success message to the controller, the button light is turned on;

When the input signal of the input module of the elevator button is detected and the button light is on, turn off the button light;

The input module is used for generating an input signal when triggered.

In this embodiment, during the initialization process, the button light is turned on every time the write success message is sent, so as to detect whether the output module of the button is normal. Detect whether the input module is triggered by turning off the button light, so as to detect whether the input module of the button is normal. The input module is also used to send the input signal to the controller to control the elevator to reach the floor corresponding to the input signal.

In one of the embodiments, when the logic control circuit is an AND gate or an NOR gate, the start signal is a high level signal.

The judgment of whether to carry out the identification setting of the next button is realized through the AND gate or the same-OR gate, which greatly saves the cost.

In one of the embodiments, the writing success information includes an analog trigger signal that triggers the start of the next elevator button;

The controller is also used to send the analog trigger signal to the elevator control system when receiving the writing success information, so as to control the elevator to run to the floor corresponding to the next elevator button.

In this embodiment, while initializing, it is also possible to detect whether the elevator is running normally.

The various technical features in the above embodiments can be combined arbitrarily, as long as there is no conflict or contradiction between the combinations of features, but due to space limitations, they are not described one by one, so the various technical features in the above embodiments can be combined arbitrarily It also belongs to the scope disclosed in this specification.

The present invention is also described by taking one of the application examples.

After the elevator calling device (such as the control box) is assembled, if it is necessary to initialize the elevator calling device before leaving the factory, the product factory inspection can be combined, which saves production man-hours and completes product inspection and initialization settings simultaneously.

As shown in Figure 2, it is a structural schematic diagram of an application example of an elevator calling device of the present invention, including: at least two elevator buttons 210, a control box control panel 220, a control line 230, and a serial communication bus 240, and the elevator button 210 includes a button A control module 211 and an AND gate circuit 212 .

The control panel of the control box enters the initialization setting and inspection mode, and the control panel of the control box sends out the information of setting ID as 1 through the serial communication bus, and at the same time, the control panel of the control box gives a high-level signal.

Since only the first button receives a high-level signal, the first button writes the ID as 1 as its own ID, and replies to the operation box control board to write a successful message, and at the same time lights up the button light. And send a high-level signal to the AND gate, because both input terminals of the AND gate circuit are high-level, then output a high-level signal to the control line outlet, that is, send a high-level signal to the button control module of the second elevator button and AND gate circuit.

When the control box control board receives the ID writing success message replied by the elevator button, it will send the next ID information, wherein the ID information is the value of the first ID information plus 1. At the same time, the second elevator button also receives a high level, so the next button can also complete the ID setting.

By analogy, when the ID value of the last button is successfully set and the message is sent back to the control panel of the control box, when the control panel of the control box sends out the set ID value of the next button, the last button judges that its own ID has been set and gives a set signal , the control board will receive the signal and confirm that all the buttons have completed the ID setting.

When the setting of the first button is completed, the light of the first button will be lit, and so on. When all the buttons are successfully lit, it means that the setting of all button IDs has been completed, and the output lighting functions of all buttons are normal.

After the output function inspection of all buttons is completed, the input function of the buttons is checked. All the buttons have completed the ID setting, and all the buttons are currently in the lighted state. At this time, the inspector only needs to press the button, and the control panel of the control box will receive the input signal of the button. When the control panel receives the input signal of the button, the feedback signal will make the button go out.

When the button is off, it means that the button can be input successfully, and the ID setting is correct. Therefore, the inspector only needs to operate all the buttons once, and then completes the inspection of whether the input of all the buttons and the set ID function are normal. After all the buttons are operated , all the buttons are turned off, and operate the control panel to exit the initialization setting and inspection mode.

The above solution can semi-automatically complete the setting of product delivery inspection and initialization at the same time. In addition, the elevator button may also include a resistor, one end of the resistor is connected to the incoming end of the control line, and the other end of the resistor is grounded.

The present invention also provides an elevator system, which includes the elevator calling device of the above-mentioned embodiments. I won't list them one by one here.

In one of the embodiments, it also includes an elevator control system, the elevator control system is used to start the self-learning mode of the elevator during initialization, and controls the elevator to run from the bottom to the top at a preset speed;

The successful writing information includes the identification setting information of the elevator button;

The controller is also used to send the elevator button information and identification setting information to the elevator control system when receiving the successful writing information;

The elevator control system receives and stores the elevator button information, identification setting information and their associated relationship.

In this embodiment, the elevator control system is connected with the elevator calling device. In this embodiment, the initial setting of the control box can be completed simultaneously during the self-learning process of the elevator. At the same time, the data recorded by the elevator control system is also conducive to the operation of elevator installation and engineering debugging. Any bad button positions can be located.

For example, after the assembly of the control box is completed, if it is ensured that the control panel of the control box, the serial button, the connection of the serial bus, and the connection of the setting ID control line are all normal, then the initial setting of the control box can be combined with the installation and commissioning of the elevator. During the self-learning process, the initialization setting of the control box is completed at the same time.

After the elevator enters the self-learning mode, the control panel of the operation box also enters the self-learning initialization setting mode at the same time, and the elevator will run from the bottom floor to the top floor at a slow speed.

When the elevator is at the lowest floor, the control panel of the control box sends out a message to set the ID to 1, and the principle is the same as above.

When the button is set successfully, it will give the simulated pressing signal of the button to the operation box control board, and then the control board will pass the button information to the elevator control system, so the elevator control system can record the ID setting of the button.

When the elevator runs from the bottom floor to the top floor, all the buttons in the control box have completed the ID setting, and at the same time, the elevator control system also records all the button settings.

When the elevator completes self-learning, the initialization of the control box is also completed. Since the elevator control system records the setting information of all buttons, the elevator control system can clearly know the initialization of the control box after the elevator self-learning is completed. Therefore, the initial setting of the control box can be completed during the self-learning process of the elevator. At the same time, the data recorded by the elevator control system is also conducive to the operation of elevator installation and engineering debugging, and can locate any bad button position.

The scheme of the invention can deal with the problem of complex wiring of elevators on high floors and super high floors, and at the same time, it is easy to operate. The ID setting of the serial button can be completed through the elevator self-learning, which can effectively solve the difficulty of setting the ID of the serial button, so that the control box can easily solve the distribution of the button ID number while the button wiring and assembly are simple, which is very convenient The operation of production assembly and engineering debugging reduces the probability of assembly errors caused by complex wiring. Only the serial bus is needed to connect all the buttons in series, which greatly reduces the material, labor and management costs of the control box.

The above-mentioned embodiments only express several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but should not be construed as limiting the patent scope of the present invention. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent for the present invention should be based on the appended claims.
