[0049] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0050] The control method provided by the embodiments of the present application can be applied to an application environment as shown in Figure 1 . Among them, the car intercom controller 102 communicates with the button controller 104, and the self - inspection button 106 is controlled by the button controller 104. The car intercom controller 102 sends a self - inspection trigger signal to the button controller 104, and the self - inspection trigger signal is used to instruct the button controller 104 to drive the electromagnet power supply circuit in the self - inspection button 106 to close; among them, when the electromagnet is energized, it magnetically attracts the button body set at intervals, so that the button body presses down the button switch, and the button switch generates a downward pressure feedback signal; when the car intercom controller 102 does not receive the downward pressure feedback signal within the first preset time, it determines that the button switch has a fault and outputs the determination result to the terminal 108. Among them, the terminal 108 can be but is not limited to various personal computers, laptop computers, smart phones, tablet computers, portable wearable devices. The portable wearable device can be a smart watch, a smart bracelet, a head - mounted device, etc.

[0051] In one embodiment, as shown in Figure 2 , a control method is provided. Taking the application of this method to the car intercom controller 102 in Figure 1 as an example, the method includes the following steps:

[0052] Step S202: Send a self-check trigger signal to the button controller; the self-check trigger signal is used to instruct the button controller to drive the electromagnet power supply circuit to close; when the electromagnet is powered on, it magnetically attracts the button body set at intervals, causing the button body to press down the button switch, and the button switch generates a downward pressure feedback signal.

[0053] Among them, the downward pressure feedback signal means that when the button body presses down the button switch, the button switch is in the on state at this time, and a high-level signal will be generated in the circuit. Specifically, in a specific embodiment, the high-level signal can be obtained by a current sensor connected in series in the button switch circuit. The self-check trigger signal is an enable signal output by the above-mentioned car intercom controller, which is used to instruct the button controller to drive the electromagnet power supply circuit to close. Specifically, for example, the self-check trigger signal can be a digital signal output by the car intercom control, specifically as Figure 3 shown. Exemplarily, the duration of both the high level and the low level is 100 milliseconds. It should be noted that the duration of the high and low levels of the digital signal here is only for illustrative purposes, and those skilled in the art can make adaptive configurations according to the actual application scenario, and are not limited here.

[0054] As Figure 4 shown, the car intercom controller can input the self-check trigger signal to the button controller through the signal input port at the call indicator light 414. Under the control of the self-check trigger signal, the button controller controls the drive electromagnet 404 power supply circuit to close. When the electromagnet is energized, it generates a magnetic field and has magnetic force. At this time, it magnetically attracts the magnetic parts such as the armature 416 in the button body, thereby pressing down the button switch 408. And when the button switch 408 is in the on state, it outputs a downward pressure feedback signal to the car intercom controller.

[0055] Step S204: If the downward pressure feedback signal is not received within the first preset time, it is determined that the button switch has failed.

[0056] Among them, the first preset time is the determination criterion in the time dimension for determining whether the car intercom controller receives the downward pressure feedback signal. In a specific embodiment, the first preset time can be 200 milliseconds. The first preset time can be the first preset time period starting from when the car intercom controller sends the self-check trigger signal. The situation where the button switch fails can be that after the button body completely presses down the button switch under the control of the self-check trigger signal, the button switch is not turned on, that is, there is no downward pressure feedback signal output at this time; further, the situation where the button switch fails can also be that the button body does not completely press down the button switch under the control of the self-check trigger signal. At this time, due to problems such as poor contact release of the button switch, it is also in the off state and no downward pressure feedback signal is output.

[0057] In the above embodiments, the self-check of the control completion button based on the car intercom controller is completed, improving the troubleshooting efficiency.

[0058] In one embodiment, as Figure 5 shown, in the case where the downward pressure feedback signal is not received within the first preset time, the steps for determining that the button switch fails include:

[0059] Step S502, iteratively execute the step of sending a self-check trigger signal to the button controller in the case where the downward pressure feedback signal is not received within the first preset time for sending the self-check trigger signal, until the end condition is met. The end condition is that the downward pressure feedback signal is received within the first preset time for sending the self-check trigger signal or the number of iterations is greater than the preset number of times.

[0060] Specifically, in the case where the downward pressure feedback signal is not received within the first preset time, the car intercom controller outputs a self-check trigger signal to the button controller again. At this time, the button controller drives the electromagnet power supply circuit to close again under the control of the self-check trigger signal. Among them, when the electromagnet is energized, the button body set with a magnetic suction interval is magnetically attracted, so that the button body presses the button switch, and the button switch generates a downward pressure feedback signal. If the downward pressure feedback signal is still not received within the first preset time, the step of sending a self-check trigger signal to the button controller is repeatedly executed. Taking this as a cycle, cyclic control is performed until the number of iterative cycles is greater than the preset number of times or during the cycle, the downward pressure feedback signal is received within the first preset time after a certain self-check trigger signal is sent, and the cycle ends.

[0061] Step S504, if the number of iterations is greater than the preset number of times, it is determined that the button switch fails.

[0062] Among them, the preset number of times refers to the determination criterion for determining whether the cycle ends and is also the reference data for determining whether the button switch fails. In a specific embodiment, the preset number of times can be three. It should be noted that in order to obtain more accurate self-check results, those skilled in the art can set it according to actual needs and are not limited herein.

[0063] To better assist those skilled in the art to understand this process, an example is given here with the preset number of times being three times, but this example does not limit the actual setting of the preset number of times. The car intercom controller first outputs a self-check trigger signal to the button controller, and the button controller controls the button body to press the button switch under the indication of the self-check trigger signal. At this time, if the car intercom controller does not receive the pressing feedback signal within the first preset time, the car intercom controller then outputs the self-check trigger signal to the button controller for the second time. If the car intercom controller still does not detect the pressing feedback signal, the car intercom controller continues to output the self-check trigger signal for the third and fourth times. At this time, if the preset number of times is set to three times, then when it comes to the fourth time, if the car intercom controller still does not receive the pressing feedback signal within the first preset time, it is determined that the button switch is faulty.

[0064] In the above embodiment, after the first button self-check is performed based on the self-check trigger signal, when the car intercom controller does not receive the pressing feedback signal within the first preset time, cyclic self-check is performed, thereby ensuring the accuracy of the self-check result.

[0065] In one embodiment, as Figure 5 shown, the control method further includes:

[0066] Step S506, if a pressing feedback signal is received within the first preset time when the self-check trigger signal is sent and the iteration count is less than the preset number of times, it is determined that the button switch is normal.

[0067] Exemplarily, the preset number of times can be set to three times. At this time, after the car intercom controller sends the self-check trigger signal to the button controller for the second time, if the car intercom controller receives the pressing feedback signal within the first preset time, it is determined that the button switch is normal, and at this time, there is no need to perform the third and fourth self-checks; for another example, if the car intercom controller does not receive the pressing feedback signal after the second self-check, at this time, the car intercom controller sends the self-check trigger signal to the button controller for the third time. If the pressing feedback signal is received within the first preset time, it is determined that the button switch is normal at this time.

[0068] In the above embodiment, after the first button self-check is performed based on the self-check trigger signal, when the car intercom controller does not receive the pressing feedback signal within the first preset time, cyclic self-check is performed, thereby ensuring the accuracy of the self-check result.

[0069] In one embodiment, as Figure 6 shown, the control method further includes:

[0070] Step S602, in the case of receiving a pressing feedback signal within the first preset time, obtain the duration of the pressing feedback signal.

[0071] Among them, the duration of the downward pressure feedback signal refers to the time when the button switch is continuously pressed by the button body. For example, in the usage scenario of an elevator car intercom, when a passenger uses the car intercom, they need to continuously press the switch button of the car intercom for the elevator car intercom to work continuously. At this time, the duration of the downward pressure feedback signal is the time when the button switch is continuously pressed by the button body.

[0072] Step S604, if the duration of the downward pressure feedback signal is greater than a second preset time, stop sending the self-check trigger signal to the button controller and control the operation of the car intercom. The second preset time is greater than the first preset time.

[0073] Among them, the second preset time is a time dimension standard for determining the state of the button switch. In a specific embodiment, the second preset time can be 500 milliseconds.

[0074] Specifically, when the duration of the downward pressure feedback signal is greater than the second preset time, it is determined that the downward pressure of the button switch is triggered by the user's pressing at this time. At this time, the self-check process is exited, the self-check trigger signal is no longer sent to the button controller, and the operation of the car intercom is controlled.

[0075] In the above embodiment, by detecting the duration of the downward pressure feedback signal and comparing the detection result with the second preset time, the result of the self-check can be determined more accurately.

[0076] In one embodiment, as Figure 6 shown, the control method further includes:

[0077] Step S602, when a downward pressure feedback signal is received within the first preset time, obtain the duration of the downward pressure feedback signal.

[0078] Step S606, if the duration of the downward pressure feedback signal is less than the second preset time, determine that the button switch is normal. The second preset time is greater than the first preset time.

[0079] Specifically, when the duration of the downward pressure feedback signal is less than the second preset time, that is, the button body rebounds within the second preset time and the button switch is in an open circuit state, it is determined that the button self-check is successful at this time, that is, it is determined that the button switch is normal.

[0080] In the above embodiment, by detecting the duration of the downward pressure feedback signal and comparing the detection result with the second preset time, the result of the self-check can be determined more accurately.

[0081] In one embodiment, as Figure 7 shown, the control method further includes:

[0082] Step S702, when it is determined that the button switch fails, generate and send an alarm message to the terminal.

[0083] In the above embodiment, after the button switch fails, the car intercom controller timely generates an alarm message and sends it to the terminal, so as to timely notify the duty personnel to conduct fault troubleshooting, ensure the normal operation of the elevator, and ensure the safety of passengers at the same time.

[0084] In one embodiment, as Figure 8 shown, a button self-checking method is provided, which is applied to the button controller 104 as Figure 1 shown. The method includes:

[0085] Step S802, obtain the self-check trigger signal sent by the car intercom controller;

[0086] Among them, the self-check trigger signal is similar in meaning to the self-check trigger signal in the above embodiment, and will not be elaborated here.

[0087] Step S804, according to the self-check trigger signal, drive the electromagnet power supply circuit to close; wherein, when the electromagnet is energized, it magnetically attracts the button switch, so that the button switch generates a downward pressure feedback signal;

[0088] Step S806, receive and send the downward pressure feedback signal to the car intercom controller, so that the car intercom controller determines that the button switch fails if it does not receive the downward pressure feedback signal within the first preset time after sending the self-check trigger signal.

[0089] In the above embodiment, the button controller completes the self-check of the button through the control based on the self-check trigger signal, improving the fault troubleshooting efficiency.

[0090] In one embodiment, as Figure 9 shown, obtaining the self-check trigger signal sent by the car intercom controller includes:

[0091] Step S902, receive and verify the self-check trigger signal sent by the car intercom controller;

[0092] Step S904, when the verification passes, obtain the self-check trigger signal sent by the car intercom controller.

[0093] Specifically, in a specific embodiment, the button controller detects the high and low level widths of the self-check trigger signal through a signal detection device integrated on the circuit board, that is, determines the duration of the high and low levels of the digital signal corresponding to the self-check trigger signal. For example, in a specific embodiment, the self-check trigger signal required by the button controller is a digital signal with high and low level durations of 100 milliseconds respectively. At this time, the button controller receives the self-check trigger signal output by the car intercom. If the self-check trigger signal meets the above requirements for the duration of the high and low levels, it is determined that the self-check trigger signal passes the verification. At this time, the button controller directly obtains the self-check trigger signal for subsequent button control operations.

[0094] In the above embodiment, by verifying the self-check trigger signal output by the car intercom and only adopting it after the verification passes, it avoids button self-check based on an incorrect self-check trigger detection signal, ensuring the accuracy of the button self-check result.

[0095] It should be understood that although the steps in the flowcharts involved in the above-described embodiments are sequentially shown according to the arrows, these steps are not necessarily executed in the order indicated by the arrows.

[0128] As Figure 4As shown in the figure, the alarm button includes: a button housing 402, an electromagnet 404, a return spring 406, a button switch 408, a button body 410, a circuit board 412, a call indicator light 414, a magnetic part such as an armature 416, and a bottom cover 418.

[0129] The self-checking process of the alarm button is as follows:

[0130] Step 1, the car intercom controller initiates a self-check.

[0131] Step 2, the car intercom controller sends a self-check trigger signal, that is, a digital signal for starting the self-check, to the button controller by controlling the duration of the high and low levels of the input ports such as the call indicator.

[0132] Step 3, the button controller determines in real time whether the input digital signal is the correct self-check trigger signal by monitoring the signal input of the call indicator input port.

[0133] Step 4, if the button controller receives the correct self-check trigger signal, it controls the button body to press down. The specific process of controlling the button body to press down is as follows: the button controller controls the electromagnet circuit to be energized, thereby generating magnetism, and then attracts the armature fixed on the button body through the magnetism to make the button body descend. When the button body descends, the button switch is turned on.

[0134] Step 5, if the car intercom controller does not receive the downward pressure feedback signal generated after the button switch is turned on within the first preset time, repeat steps 2 to 4. If the downward pressure feedback signal is still not received after repeating 3 times, it is determined that the button self-check fails, that is, it is determined that the button is faulty, and the self-check state is exited.

[0135] Step 6, after the car intercom controller receives the downward pressure feedback signal, it waits for the button body to rebound.

[0136] Step 7, if the button body does not rebound within the second preset time, at this time it is determined that the downward pressure action of the button body is triggered by the passenger, the self-check is cancelled, and the car intercom controls the intercom to enter the intercom call state.

[0137] Step 8, if the button body rebounds within the second preset time, the button switch self-check is successful, that is, it is determined that the button switch is normal, and the self-check state is exited.

[0138] Among them, after the intercom enters the intercom call state in step 8, the specific state of the car intercom indicator light is as follows:

[0139] After pressing the button body, the car intercom is in the state of calling and connecting to the monitoring center, and the call indicator light is on.

[0140] After the monitoring center host answers the call, the call indicator light is on.

[0141] After hanging up or in the standby state, both indicator lights are turned off.

[0142] In the above embodiment, through the control of the car intercom controller, the self-check of the alarm button is completed, thereby improving the efficiency of troubleshooting.
