Description

Technical Field

[0001] The invention relates to the technical field of elevator safety, and in particular to a household elevator sound and light alarm system and a control method. Background Art

[0002] In today's society, with the accelerating process of population aging, the application of home elevators in the residential field has shown a significant growth trend. As a vertical transportation tool specifically serving single family users, home elevators have their own unique usage characteristics compared to public elevators widely used in large public buildings, such as relatively small number of passengers and low frequency of use.

[0003] However, precisely because home elevators are mainly used in non-public home environments, once a malfunction occurs that traps people, how to ensure that the trapped people can send out distress signals in a timely and effective manner and receive rescue becomes a crucial issue.

[0004] Traditional home elevator emergency call solutions mostly use a five-party call function configuration. In this solution, with the help of the alarm button of the car intercom, the trapped person can establish contact with the intercom sub-machines at multiple locations such as the top of the elevator car, the elevator machine room, the bottom of the elevator shaft, and the monitoring center, and then make a call for help. However, this traditional solution has many disadvantages. In terms of hardware configuration, it is necessary to install multiple intercoms at different locations of the elevator, which not only increases the purchase cost of the equipment, but also during the on-site construction process, due to the complex wiring work involved, a large number of communication lines need to be laid, which undoubtedly greatly increases the difficulty and cost of construction, and also prolongs the installation period of the elevator.

[0005] In order to solve the problems existing in the configuration of the traditional five-party call function, a new solution has emerged in recent years - the one-button external call function. This solution integrates a mobile network module into the elevator intercom system, so that the car intercom can directly communicate with the mobile phone to realize external calls for help. The advantage of this solution is that it successfully eliminates the tedious wiring work and reduces the cost and construction difficulty to a certain extent. However, this solution also has an obvious defect, that is, it is highly dependent on mobile network signals. In actual use, once the network signal is poor, such as in some remote areas or areas with weak signal coverage inside buildings, the elevator's one-button external call function will not work properly, resulting in the trapped personnel unable to contact the outside world in time, thereby greatly increasing the risk of trapped personnel and the difficulty of rescue.

[0006] To sum up, the existing home elevator emergency call solutions all have their own limitations, and it is difficult to meet the needs of home elevators for safe and reliable emergency call functions in various complex environments. Therefore, there is an urgent need for a new and more effective home elevator sound and light alarm system and control method to fill this technical gap in order to ensure the life safety and user experience of home elevator users. Summary of the invention

[0007] The purpose of the present invention is to provide a sound and light alarm system and control method for a home elevator, which not only eliminates the cumbersome wiring of the traditional five-party call system, reduces the configuration cost and construction difficulty, but also overcomes the defect that the one-button external call function cannot call for help when the network signal is poor, and provides a reliable new way to call for help. By retaining the traditional voice call function with the outside in the car and adding sound and light alarm reminders, outsiders can learn about the situation of people trapped in the car through various channels, such as seeing flashes, hearing rings, or receiving mobile network calls, so as to implement rescue more quickly, effectively improving the rescue efficiency and reliability of home elevators when people are trapped, ensuring the safety of users, and allowing users to use elevators with more peace of mind.

[0008] The present invention is achieved through the following technical solutions:

[0009] A household elevator sound and light alarm system, comprising:

[0010] Alarm button: Installed in a conspicuous and easy-to-operate place in the car, such as a conspicuous corner of the car operation panel. Its main function is to trigger the emergency call function of the car intercom. When the trapped person presses it, the entire alarm process is started.

[0011] Car intercom: It has an intercom module, which can communicate with other relevant personnel (such as monitoring center personnel and the intercom terminal corresponding to the preset rescue personnel's mobile phone APP) through voice intercom; it also has a communication module, which can connect to the mobile communication network (such as supporting 4G, 5G and other standards) to realize mobile intercom communication. It also establishes a communication connection with the car top control panel to transmit the alarm button trigger signal and the phone connection signal to the car top control panel.

[0012] Car top control panel: It is installed on the top of the elevator car, and its communication interface is connected to the main control panel and the car intercom. It is responsible for receiving the alarm button trigger signal and the phone connection signal from the car intercom, and accurately forwarding these signals to the main control panel. In addition, the car door lock switch is connected to its MCU to monitor the opening and closing status of the car door in real time, and transmit the status information to the system to provide a basis for subsequent rescue judgment.

[0013] Main control board: installed in the control box of the elevator control system, maintains a stable communication connection with the car top control board, and receives the alarm button trigger signal, phone connection signal and car door lock signal from the car top control board. When the MCU of the main control board receives the alarm button trigger signal, it drives the flash buzzer to ring and flash continuously through the output port, and sends out sound and light alarm information. At the same time, the main control board is also connected to the hall call module through the communication line to receive the button call signal from the hall call module to determine whether there are external personnel to come to rescue.

[0014] Flash buzzer: driven and controlled by the main control board, installed at the user-specified location so that the flash and sound can be clearly seen outside the car. Its main function is to provide eye-catching flash and sound reminder information when someone is trapped in the elevator and the alarm is triggered, attracting the attention of people around and informing them that someone in the car needs help.

[0015] Car door lock switch: installed at the door lock mechanism of the car door and connected to the car top control board. When the car door is opened, the switch state changes, and the car top control board transmits this signal to the main control board. The main control board determines that the car door has been opened, which means that rescuers may have arrived and opened the car door to rescue the trapped people. At this time, the main control board can disconnect the drive of the flashing buzzer and release the sound and light alarm.

[0016] Hall call module: installed on the operation panel outside the elevator hall door, used to provide a button call signal. When an outsider hears or sees the elevator sound and light alarm, comes to the elevator hall and presses or long presses any hall call button on a certain floor, the hall call module transmits the button call signal to the main control board. After receiving the signal, the main control board believes that rescuers have arrived at the elevator to carry out rescue, and thus disconnects the drive of the flash buzzer and releases the sound and light alarm.

[0017] Power module: Provides power support for all components of the entire system and has the function of power supply during power outages. Under normal mains power supply conditions, it can stably supply power to all components of the system; when encountering a power outage, it can automatically switch to emergency power supply mode to ensure that the sound and light alarm system can still work normally for at least 1 hour during a power outage, giving priority to ensuring the power supply of components related to the sound and light alarm to cope with the situation where people may be trapped in the elevator during a power outage.

[0018] As a further improvement of the technical solution of the invention, the communication module of the car intercom supports multiple mobile communication network standards.

[0019] As a further improvement to the technical solution of the invention, the flash frequency and sound volume of the flash buzzer are adjustable.

[0020] As a further improvement of the technical solution of the invention, the communication between the main control board and the car top control board adopts a wired or wireless method.

[0021] As a further improvement to the technical solution of the invention, the power module preferentially supplies power to components related to the sound and light alarm during a power outage.

[0022] As a further improvement of the technical solution of the invention, a method for controlling sound and light alarms of a home elevator comprises:

[0023] When someone in the car presses the alarm button, the car intercom immediately activates the mobile network function of the communication module to make an external call and try to contact the mobile phone of the preset rescue personnel (such as family members, property management personnel, etc.). At the same time, the car intercom transmits the alarm button trigger signal to the car top control board through the internal communication line. After receiving the signal, the car top control board quickly forwards it to the main control board. After receiving the alarm button trigger signal, the main control board drives the flash buzzer to start ringing continuously and flashing at a specific frequency, sending out an audible and visual alarm signal to attract the attention of people around.

[0024] There are several situations for releasing the sound and light alarm:

[0025] If the mobile network call is successfully connected, the car intercom transmits the call connection signal to the main control board through the car top control board. After receiving the signal, the main control board determines that the rescue personnel have learned that there are people trapped in the car, and then disconnects the drive of the flash buzzer, cancels the sound and light alarm, and waits for the rescue personnel to further arrange the rescue work.

[0026] If an outsider hears the sound and light alarm and rushes to the elevator, and opens the elevator car door, the car door lock switch state changes, and the system receives a signal that the car door is opened. The car top control board transmits the signal to the main control board, which determines that the rescue personnel have arrived and opened the car door, and then disconnects the drive of the flash buzzer, releases the sound and light alarm, and the trapped people are rescued.

[0027] If an outsider hears or sees the sound and light alarm, comes to the elevator hall and presses or long presses any hall call button on a certain floor, the hall call module transmits the button elevator call signal to the main control board. After receiving the signal, the main control board believes that the rescue personnel have arrived near the elevator, and then disconnects the drive of the flash buzzer and releases the sound and light alarm. Then the rescue personnel can further operate to open the car door for rescue.

[0028] In summary, the present invention has the following beneficial effects:

[0029] The household elevator sound and light alarm system and control method of the present invention not only eliminates the cumbersome wiring of the traditional five-party call system, reduces the configuration cost and construction difficulty, but also overcomes the defect that the one-button external call function cannot call for help when the network signal is poor, and provides a new reliable external call for help.

[0030] By retaining the traditional voice call function between the cabin and the outside and adding sound and light alarm reminders, outsiders can learn about the situation of people trapped in the cabin through various channels, such as seeing flashes, hearing sounds, or receiving mobile network calls, so that rescue can be implemented more quickly. This effectively improves the rescue efficiency and reliability when a home elevator entraps people, ensures the safety of users, and allows users to use elevators with greater peace of mind.

[0031] The power module has the function of power supply during power outages, ensuring that the sound and light alarm system can still work normally for at least 1 hour during a power outage, further enhancing the reliability of the system under special circumstances and ensuring that trapped people can receive rescue attention in a timely manner during a power outage.

Then the rescue personnel can further operate to open the car door for rescue.

[0054] Example:

[0055] System component installation and connection

[0056] The alarm button is installed in a conspicuous and easy-to-operate position on the car operating panel and is connected to the car intercom through a dedicated line to ensure that the signal can be accurately transmitted when pressed, triggering the emergency call function of the car intercom.

[0057] The car intercom is installed at a suitable position inside the car. Its intercom module establishes a stable connection with other related intercom sub-machines, the communication module is connected to the mobile communication network, and is connected to the car top control panel through high-quality communication cables to ensure stable and fast transmission of the alarm button trigger signal and the telephone connection signal.

[0058] The car top control panel is installed on the elevator car top, and its communication interface is connected to the car intercom and the main control panel through shielded communication cables to prevent signal interference and ensure accurate signal transmission. The car door lock switch is connected to the MCU of the car top control panel. The connection line must ensure the accuracy and timeliness of signal acquisition in order to monitor the state changes of the car door in real time.

[0059] The main control board is installed in the control box of the elevator control system, and is connected to the car top control board through a reliable communication line (wired or wireless, depending on actual needs and elevator environment), receives the signal forwarded from the car top control board, and is connected to the flash buzzer through the output line. The control line must have sufficient power driving capability to ensure that the flash buzzer can sound and flash normally. At the same time, the main control board is connected to the hall call module through a dedicated communication line to receive the signal from the hall call button to ensure the stability of signal transmission.

[0060] The flash buzzer is installed at the location specified by the user. Its installation angle and position must ensure good visibility and audibility. The connection line with the main control board must meet the electrical safety standards to ensure that the main control board can effectively drive it to work and send out strong sound and light alarm signals.

[0061] The car door lock switch is installed at the door lock mechanism of the car door. The connection line with the car top control panel must have good anti-interference and stability. When the car door is opened or closed, it can accurately feedback the door status information to the system, providing a reliable basis for rescue judgment.

[0062] The hall call module is installed on the operation panel outside the elevator hall door, establishes a stable communication connection with the main control board, and transmits the button elevator call signal to the main control board. Its installation must comply with the design specifications and electrical safety requirements of the elevator operation panel.

[0063] The power module is installed in the elevator room or a suitable power supply location, connected to the mains and equipped with the emergency power supply function. It supplies power to all components of the system through the distribution line, and automatically switches to the emergency power supply mode in the event of a power outage, giving priority to ensuring the normal operation of the sound and light alarm system for at least 1 hour. The capacity and performance of the power module must meet the power demand of the system during a power outage, and its switching circuit must be fast and reliable to ensure that it can quickly switch to the emergency power supply in the event of a mains power outage.

[0064] System operation process

[0065] During normal operation, the power module provides stable power supply to each component, each communication line remains unobstructed, and each sensor (such as the car door lock switch) is in a monitoring state but no abnormal signal is output.

[0066] When someone is trapped in the car, the passenger presses the alarm button, and the car intercom immediately activates the mobile network communication module to make an external call, trying to contact the preset rescue personnel (such as family members, property management personnel, etc.) by mobile phone. At the same time, the car intercom transmits the alarm button trigger signal to the car top control board through the communication line, and the car top control board quickly forwards the signal to the main control board. After receiving the signal, the main control board drives the flash buzzer to ring continuously and flash at a specific frequency through the output port, sending out an audible and visual alarm signal. At this time, the flashing and ringing of the flash buzzer are clearly visible and audible at the installation location, attracting the attention of people around.

[0067] During the alarm process:

[0068] If the mobile network call is connected, the car intercom will transmit the call connection signal to the car top control board, and the car top control board will forward the signal to the main control board. After receiving the signal, the main control board will disconnect the drive of the flash buzzer and release the sound and light alarm, because at this time the rescue personnel have learned that there are people trapped in the car and can make subsequent rescue arrangements.

[0069] If an outsider hears the sound and light alarm and rushes to the elevator and opens the car door, the car door lock switch state changes, and the car door opening signal is transmitted to the car top control board. The car top control board notifies the main control board, and the main control board disconnects the drive of the flashing buzzer and releases the sound and light alarm, indicating that the trapped person has been rescued.

[0070] If an outsider hears or sees the sound and light alarm, comes to the outside of the elevator hall and presses or long presses any hall call button on a certain floor, the hall call module transmits the button elevator call signal to the main control board. After receiving the signal, the main control board believes that the rescue personnel have arrived near the elevator, disconnects the drive of the flashing buzzer, cancels the sound and light alarm, and waits for the rescue personnel to further operate to open the car door for rescue.

[0071] The home elevator sound and light alarm system and control method of the present invention effectively solve the problems existing in the traditional home elevator rescue scheme, which not only reduces the cost and construction difficulty, but also improves the reliability and rescue efficiency of calling for help when people are trapped. At the same time, it can still ensure the ability of trapped people to call for help in the event of a power outage, and has significant innovation and practicality.

[0072] The household elevator sound and light alarm system and control method proposed by the present invention have many significant beneficial effects:

[0073] Cost and construction advantages:

[0074] Compared with the traditional five-party calling system, the present invention eliminates the need for complicated wiring work. There is no need to lay a large number of communication lines for connecting multiple intercoms at various locations in the elevator, which directly reduces the cost of wiring materials, such as cables, wire ducts, etc. At the same time, the labor costs required for wiring construction are reduced, including the labor costs of wiring workers and other costs that may be incurred during the construction process, such as the cost of repairing minor damage to the elevator shaft or car structure caused by wiring. In addition, since the number of intercoms is reduced, the equipment procurement cost is further reduced, and the configuration cost and construction difficulty of the home elevator alarm system are greatly reduced as a whole, making the installation of home elevators more convenient and efficient, which is conducive to shortening the installation cycle of the elevator and reducing the time cost of users waiting to use the elevator.

[0075] Reliable emergency support:

[0076] The defect that the one-button external call for help function cannot call for help when the network signal is poor has been overcome. The present invention adds an audible and visual alarm reminder function on the basis of retaining the function of the mobile network communication module of the car intercom to make external calls. When the mobile network signal is normal, the car intercom can make a call for help normally; when the network signal is poor or the call cannot be connected, the flash buzzer continues to ring and flash, which can attract the attention of other people in the house or nearby neighbors, and provides trapped people with a reliable way to call for help that does not rely on network signals. This multi-channel call for help method greatly increases the probability of trapped people sending out distress signals and being discovered in various complex environments, effectively ensures that trapped people can get rescue in time, and reduces the physiological and psychological risks faced by trapped people who are trapped in the car for a long time due to failed calls for help.

[0077] Efficient rescue response:

[0078] By retaining the traditional voice call function between the cabin and the outside and adding an audible and visual alarm reminder, the possibility of outsiders being informed of the situation of people trapped in the cabin is greatly increased. Outsiders may learn of the situation of people trapped in the cabin by hearing the sound of the flash buzzer, seeing the flash, or receiving a mobile network call. Once outsiders notice it, whether they are family members, property staff or nearby neighbors, they can respond more quickly and implement rescue. For example, when someone hears the audible and visual alarm and rushes to the elevator and opens the cabin door, or triggers the release of the audible and visual alarm and further implements rescue operations outside the hall by pressing the elevator call button, the trapped people can be rescued faster, significantly improving the rescue efficiency when the home elevator is trapped, and reducing the time trapped people are trapped, thereby maximizing the protection of users' lives, improving users' sense of security and satisfaction with the use of home elevators, and allowing users to use elevators with more peace of mind.

[0079] Power outage emergency reliability:

[0080] The power module has the function of power supply during power outages, and can ensure that the sound and light alarm system can work normally for at least 1 hour in the event of a power outage. This feature is particularly important when a sudden power outage causes people to be trapped in the elevator. Even in the power outage, the trapped person can still trigger the sound and light alarm by pressing the alarm button to attract outside attention and ask for help. Compared with some elevator alarm systems that do not have the power outage emergency function, the present invention can continue to play a role in the special and more common emergency situation of power outages, further enhancing the reliability of the entire home elevator system under special working conditions, and providing a strong guarantee for the life safety of trapped persons during power outages, avoiding the dangerous situation of trapped persons having no way to seek help due to power outages.

Specific examples are used herein to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention. At the same time, for those skilled in the art, according to the embodiments of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
