Description

Technical Field

[0001] The utility model belongs to the technical field of intelligent control and relates to an elevator control module, in particular to an elevator interactive system control module based on index and voice interactive functions. Background Art

[0002] With the continuous growth of my country's urban population, the number of high-rise residential buildings is also increasing rapidly, and elevators are becoming more and more widely used. According to public data from the China Elevator Association, as of the end of 2018, the total number of registered elevators in China reached 6.2783 million. Driven by both stock and increment, the number of elevators in my country will exceed 10 million in 2023. Traditional elevators use contact control methods such as button control, but the buttons are prone to aging and damage after a long time of use, and the contact control method also has the risk of spreading bacteria and viruses. For example, during the epidemic prevention and control period, in order to prevent the spread of viruses through elevator buttons, each residential community needs to disinfect the elevator every day, and hand disinfectants, disinfectant tissues and other items are also placed in the elevator. In order to avoid direct contact with the elevator buttons, people will also use keys, toothpicks and other items to assist in touching the buttons. Although it has a certain effect, if it is in public places such as hospitals and shopping malls, due to the large number of people and complex usage, the use of elevators will be more worrying.

[0003] At present, the contactless elevators on the market mainly include intelligent interactive elevators based on machine vision such as face recognition and gesture recognition. These elevators are basically used around the floors of the community. When using them, it is necessary to enter the information of the residents and the floor they are on. The information entry process is cumbersome, which is not conducive to the operation and use of residents on floors other than the floor they are on. When using them, they still cannot free their hands and there is a possibility of accidental contact. In addition, some elevator manufacturers have begun to develop voice-activated elevators, but through investigation, it is found that the existing voice-activated elevators are basically implemented by implanting ready-made offline modules. There are misidentification and missed recognition phenomena during peak hours, and there is no floor indexing function. The recognition speed is slow and it is inconvenient to use. Utility Model Content

[0004] The utility model aims at the above-mentioned technical schemes of visual intelligent interactive elevators, which are highly dependent on the amount of input information and are not conducive to operation by people without information; the existing voice elevators have the disadvantages of wrong recognition, missed recognition, no floor indexing function, and slow recognition speed. The utility model proposes an intelligent elevator interactive system control module, which can achieve rapid response to multiple calls, improve recognition speed, realize floor indexing function, and further meet the elevator needs of different groups of people.

[0005] The intelligent elevator interactive system control module provided in this application adopts the following technical solutions:

[0006] The intelligent elevator interactive system control module comprises an elevator base, an outer car, an inner car, a power module arranged in the outer car, an elevator call button arranged on the inner wall of the inner car, and a tractor connected to the inner car; characterized in that the control module also comprises:

[0007] An infrared induction switch, connected to the power module and fixedly arranged on the outer car;

[0008] An index control unit, which is arranged on the inner wall of the inner car and connected to the infrared sensor switch, and is used for inputting floor or shop information;

[0009] A voice control unit, connected in parallel with the index control unit and having an output connected to an elevator call button;

[0010] An external microphone is arranged on the outer wall of the outer car and is connected to the index control unit and the voice control unit respectively;

[0011] The control cabinet is composed of a main control board, a PLC and a frequency converter, one end of which is connected to the elevator call button control, and the other end of which is connected to the traction device control.

[0012] By adopting the above technical solution, passengers are identified through infrared sensing switches, and the elevator is notified to go to the corresponding floor. While waiting for the elevator, the index control unit and the voice control unit are started, and the passenger communicates with the voice board through the external microphone. When the passenger can only say the name of the store, the index control unit can be used to compare the information stored in the library. The voice control unit will quickly inform the floor where the store is located and notify the elevator to go to the corresponding floor. When the passenger directly says the floor he wants to go to, the index control unit can be skipped. After the voice control unit receives the floor information, it notifies the elevator to go to the designated floor. There is no contact between the passenger and the elevator throughout the whole process, and the elevator ride is completed in the question and answer process.

[0013] Furthermore, the infrared sensing switch is integrated with an infrared switch and an incoming call trigger switch, and is centrally arranged on the top of the outer car. Its sensing angle is 120° and its sensing distance is not less than 3 meters.

[0014] By adopting the above technical solution, when someone approaches the infrared sensing switch, the infrared sensing switch will output a 12V voltage to power the incoming call trigger switch. At the same time, the relay on the incoming call trigger switch is closed once, and the relay is incorporated into the elevator call button, which is equivalent to pressing the button once, thereby realizing the automatic elevator call function.

[0015] Furthermore, an internal microphone is provided on the inner wall of the inner car, and the internal microphone is connected to the index control unit and the voice control unit respectively.

[0016] By adopting the above technical solution, passengers communicate with the voice board through the external call microphone in the elevator hall and say the floor they want to go to. If multiple people call the elevator continuously and the external call microphone misses the elevator call information, they can enter the elevator and continue to call the elevator through the internal call microphone.

[0017] Furthermore, the index control unit is composed of a development board and a voice module with a relay output function.

[0018] By adopting the above technical solution, the development board inputs dialect command entries and burns them into the system. In actual use, the system can recognize the dialect after comparison, which can meet the elevator needs of local elderly people.

[0019] Furthermore, the voice control unit is an ASR voice recognition development module.

[0020] By adopting the above technical solution, the voice control unit is an intelligent interactive dialogue voice relay module that supports RS485 and RS232 interfaces. After the voice control unit is used in conjunction with the index control unit, the voice recognition rate can reach 98%, which can further reduce the missed recognition rate.

[0021] Furthermore, the PLC model is Mitsubishi FX3U series.

[0022] By adopting the above technical solutions, the PLC adopts the third-generation micro programmable controller, strengthens the instruction function, and provides up to 209 application instructions. A high-speed adapter is added to achieve high-speed counting of up to 8 channels and up to 200KHZ, which can ensure the rapid processing of the voice module input information.

[0023] Furthermore, the inverter model is Mitsubishi FR-E700 multi-function inverter.

[0024] By adopting the above technical solution, precise control of the elevator traction motor can be achieved, with a power range of 0.1-55KW, and it has the advantages of high efficiency, low noise, and high reliability.

[0025] In summary, the present invention includes at least one of the following beneficial technical effects:

[0026] (1) The utility model connects the index control unit and the voice control unit to form a combination. Since the two control units each have a set of audio recording devices, the function of quickly responding to multiple calls can be realized, which greatly improves the recognition speed.

[0027] (2) The utility model can realize the whole process of non-contact between passengers and elevators, and complete the elevator riding process during the question-and-answer session, completely freeing the hands, reducing the risk of virus transmission when touching buttons in public places, and at the same time making it convenient for passengers who carry items in both hands when riding the elevator.

[0028] (3) In the present invention, the trigger mode, variable redefinition, and control mode can be used to sequentially input the names of merchants or stores on each floor to realize the floor indexing function, which complements the voice control function.

[0029] (4) The index control unit in the utility model is composed of a voice module with a development board and a relay output function. The development board inputs dialect command entries and burns them into the system. In actual use, the system can recognize the dialect after comparison, which meets the needs of local elderly people to take the elevator and further meets the needs of multiple groups of people.

After reading the present invention, modifications to various equivalent forms of the present invention by those skilled in the art fall within the scope defined by the claims attached to this application.

[0035] Example 1

[0036] like Figure 1-3As shown, the intelligent elevator interactive system control module includes an elevator base 1, an outer car 2 fixedly set on the elevator base 1, an inner car 3 that moves up and down in the outer car 2, a power module is arranged inside the outer car 2, a call button 9 is arranged outside the outer car 2, a tractor 11 is arranged on the top of the elevator, and the inner car 3 is lifted and lowered by the tractor 11, and an infrared sensor switch 5 is fixedly arranged on the outer car 2; an index control unit 6 is arranged on the inner wall of the inner car 3 and connected to the infrared sensor switch 5; a voice control unit 7 is connected in parallel with the index control unit 6 and the output is connected to the call button 9; an external call microphone 4 is arranged on the outer wall of the outer car and is connected to the index control unit 6 and the voice control unit 7; a control cabinet 10 is arranged on the top of the elevator, and the control cabinet 10 is composed of a main control board, a PLC and a frequency converter. Specifically, the PLC Mitsubishi FX3U series adopts the third-generation micro programmable controller, which strengthens the instruction function and provides up to 209 application instructions. A high-speed adapter has been added to achieve high-speed counting of up to 8 channels and up to 200KHZ, which can ensure the rapid processing of the voice module input information. The inverter model is Mitsubishi FR-E700 multi-function inverter, which can achieve precise control of the elevator traction motor, with a power range of 0.1-55KW, and has the advantages of high efficiency, low noise, and high reliability. One end of the control cabinet 10 is connected to the elevator call button 9 for control, and the other end is connected to the traction device 11 for control. The power module is connected to the infrared sensor switch 5, the index control unit 6, and the voice control unit 7 for power supply.

[0037] Example 2

[0038] like Figure 1 As shown, in order to enhance the recognition effect of infrared sensing, in this embodiment, the infrared sensing switch 5 is integrated with the infrared switch and the incoming call trigger switch. Specifically, the infrared sensing switch 5 is centrally arranged on the top of the outer car 2, and its sensing angle is 120°, and the sensing distance is not less than 3 meters. When someone approaches the infrared sensing switch 5, the infrared sensing switch 5 outputs a 12V voltage to power the incoming call trigger switch, and at the same time, the relay on the incoming call trigger switch is closed once, and the relay is incorporated into the elevator call button, which is equivalent to pressing the button once, realizing the automatic elevator call function.

[0039] like Figure 2 As shown, in order to prevent the external microphone 4 from missing the elevator call information when multiple people continuously call the elevator outside the elevator, in this embodiment, an internal microphone 8 is arranged on the inner wall of the inner car 3, and the internal microphone 8 is respectively connected to the index control unit 6 and the voice control unit 7. If the external microphone 4 misses the elevator call information, the user can enter the elevator and continue to call the elevator through the internal microphone 8.

[0040] like Figure 3As shown, in order to meet the needs of local elderly people to take the elevator, the index control unit 6 in this embodiment is composed of a voice module with a development board and relay output function. Specifically, the voice control unit is an ASR voice recognition development module that supports RS485 and RS232 interfaces. After the voice control unit is used in conjunction with the index control unit, the voice recognition rate can reach 98%, which can further reduce the missed recognition rate. The development board enters the dialect command terms and burns them into the system. In actual use, the system can recognize the dialect after comparison.

[0041] like Figure 3 As shown in the figure, the working principle of the intelligent elevator interactive system control module is as follows: when a passenger approaches the elevator entrance, the infrared sensor switch recognizes the passenger on the floor, the infrared switch is activated, and a 12V voltage is output to the incoming call trigger switch (the incoming call trigger switch is connected in parallel with the floor call button). The trigger switch is closed once, which is equivalent to pressing the floor call button once, realizing the automatic call function and notifying the elevator to reach the corresponding floor. While waiting for the elevator, the voice control unit and the index control unit are activated at the same time to ask the passenger about the store or company he wants to go to. The passenger communicates with the voice control unit through the elevator hall's external call microphone and says the floor or shop he wants to go to. The voice control unit informs the passenger of the floor by comparing the floor information burned in the chip, and notifies the elevator system to go to the designated floor; if the passenger clearly knows the floor he wants to go to, he can skip the index control unit and directly say the floor he wants to go to. The voice control unit receives the floor information and notifies the elevator to go to the designated floor. If multiple people call the elevator continuously, the external call microphone misses the call information and can enter the elevator and continue to call the elevator through the internal call microphone. The voice control control unit and the index control unit are connected in parallel to the control panel in the control cabinet, and the corresponding points of the control panel are connected to the I / O port of the PLC. Finally, the frequency converter receives the signal from the PLC to control the start and stop and running speed of the traction motor. The utility model can be embedded in a new elevator control system or installed in an existing elevator system. Passengers have no contact with the elevator throughout the whole process, and the elevator riding process can be completed in the question-and-answer session, which can completely free the hands of passengers.
