Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to an electric vehicle alarm linkage device with voice prompts. Background Art

[0002] In recent years, the increasing number of spontaneous combustion incidents involving electric vehicles, particularly in residential buildings, has caused significant casualties and property damage. According to incomplete statistics, 90% of electric vehicle fires resulting in casualties occur indoors, in hallways, hallways, stairwells, and elevator cabins. Fires caused by electric vehicles entering elevators have become a serious threat to public life and property safety, garnering widespread public concern and the attention of relevant departments. Consequently, banning electric vehicles from entering elevator cabins has become a consensus and a fundamental demand.

[0003] The commonly used solution at present is to install an electric vehicle identification device in the elevator car. When an electric vehicle is detected entering the car or the designated area at the elevator lobby door, the identification device outputs a control signal (dry contact or communication form). By connecting this output in series with the output point of the elevator light curtain or the door opening button, the elevator door is kept in the fully open state and the elevator stops running.

[0004] However, when the elevator light curtain malfunctions or the door-opening button is stuck, the elevator door cannot close and cannot operate normally. To improve operating efficiency, a forced door-closing function is generally provided. That is, when the elevator door cannot close and operate due to a light curtain malfunction or a stuck door-opening button, the elevator door will be forced to close at a low speed after a period of time, accompanied by a warning sound, to ensure the elevator's operating efficiency. Therefore, regardless of whether the control point of the electric vehicle identification device is connected in series with the output point of the elevator light curtain or the elevator door-opening button, as long as the elevator's forced door-closing function is in effect, the door cannot be kept open at all times, and electric vehicles cannot be successfully prevented from entering the elevator car. However, if the forced door-closing function is disabled, when the light curtain malfunctions (for example, dust on the surface of the light curtain's photosensitive element) or the door-opening button is stuck, the elevator door will continue to close and cannot operate, reducing the elevator's operating efficiency. Therefore, it is necessary to provide an electric vehicle alarm linkage device with voice prompts to solve the above-mentioned existing problems, so that it can accurately and efficiently identify and effectively control the behavior of electric vehicles entering the elevator car, while not affecting other functions and operations of the elevator.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-2 The utility model provides a technical solution: an electric vehicle alarm linkage device with voice prompts, comprising an electric vehicle identification device installed in an elevator car and a main control board 1 for controlling the elevator, one end of the main control board 1 is respectively connected to an interface board 2 for connecting to the electric vehicle identification device, a display board 3 for displaying reminders, and a voice board 4 for voice alarms, one end of the display board 3 is connected to an alarm light for flashing, and the interface board 2 is connected to a release switch for temporarily releasing the electric vehicle control mode.

[0021] The electric vehicle identification device performs image acquisition and processing through a surveillance camera installed in the elevator, and then sends the acquired image information to a processor that obtains the image information. The electric vehicle identification device uses common knowledge technology in this field, such as the electric vehicle identification method, device and system disclosed in the patent document application number 201910505713.6, and the electric vehicle identification device disclosed in the document, so it will not be described in detail here.

[0022] Specifically, the interface board 2 is provided with a radio frequency connector for connecting the electric vehicle identification device, and the radio frequency connector is provided with a linkage point for linkage with the electric vehicle identification device. One end of the linkage point is connected to one end of the release switch, and the other end of the release switch is connected to the radio frequency connector. The release switch is installed in the elevator car driver's panel and is used to temporarily release the electric vehicle control mode, which will automatically recover after a certain period of time.

[0023] The output point of the electric vehicle identification device is connected through a linkage point. When the electric vehicle identification device installed in the elevator car detects that an electric vehicle has entered the car or the designated area at the elevator lobby door, the elevator door will be kept open and the elevator will stop running. This is unrelated to the output point of the elevator light curtain and the door opening button, and is not affected by the elevator's forced door closing function. While ensuring that electric vehicles can be successfully prevented from entering the car, it has no impact on other functions and actions of the elevator.

[0024] The display panel 3 is provided with a control interface for connecting an alarm light. One end of the alarm light is connected to a resistor R1, and the other end of the resistor R1 is connected to the control interface. The resistor R1 is used to provide voltage division protection for the alarm light. When an electric vehicle enters the elevator car, the alarm light flashes to give a visual warning.

[0025] The interface board 2, main control board 1, and voice board 4 are each equipped with an RS485 interface. Each of these RS485 interfaces is equipped with two data processing units U1. These two units U1 are connected in parallel, facilitating data communication between the interface board 2, main control board 1, and voice board 4 via the RS485 interface. Unit U1 is a microprocessor that receives data via the RS485 interface. The received data is first sent to unit U1 for processing, and then the corresponding operation is performed based on the processing results. The two parallel units U1 improve the speed and reliability of data processing. If one unit U1 fails, the other unit U1 can take over its work, ensuring the normal operation of the system. Furthermore, the two units U1 can also process data in parallel, increasing the speed of data processing.

[0026] The voice board 4 is provided with a calculation unit U2, and one end of the calculation unit U2 is connected to a buzzer, so as to provide voice prompts through the buzzer and give auditory warnings to people.

[0027] The main control board 1 is provided with a connector CAR for connecting to the voice board 4 and the interface board 2. A plug-in JP7 for controlling on / off is connected between pins 2 and 4 of the connector CAR. A resistor R2 is connected between pins 3 and 4 of the connector CAR. Pin 4 of the connector CAR is connected to a plug-in JP3 via a resistor R3. The other two ends of the plug-in JP3 are respectively connected to pins 1 and 3 of the connector CAR. The resistor R2 is used for current limiting and voltage division to provide overvoltage protection for the branch circuit connected to the resistor R2.

[0028] In order to speed up the system's response to abnormal situations, it also includes a communication board for transmitting the electric vehicle control status to the monitoring center. One end of the communication board is electrically connected to the main control board 1. The communication board can transmit the elevator's operating status and fault information to the monitoring center in real time. Maintenance personnel can remotely diagnose and handle elevator problems through the monitoring center, thereby improving the efficiency of electric vehicle control.

[0029] like Figure 2 As shown, when an electric vehicle is detected entering the elevator car or the designated area at the elevator lobby entrance, the elevator determines whether it is in fully automatic operation. If the elevator is in fully automatic operation, it confirms whether the electric vehicle control release switch is in the release position. If not, the elevator enters electric vehicle control mode. This mode includes: the elevator door remains open and stops operation; a voice alarm message is broadcast repeatedly; an audible and visual alarm is continuously emitted; a display prompt is continuously displayed; and a remote alarm is sent to the monitoring center. Once in electric vehicle control mode, the elevator continuously checks whether the electric vehicle has exited the car. If the electric vehicle has not exited the car, the elevator remains in electric vehicle control mode. If the electric vehicle has exited the car, the elevator releases and exits electric vehicle control mode, the audible and visual alarms, the voice and display prompts are discontinued, and normal operation resumes. If the elevator is not in fully automatic operation, or the electric vehicle control temporary release switch is in the release position and the automatic exit time has not yet been reached, the elevator is prohibited from entering or exiting electric vehicle control mode. The audible and visual alarms, the voice and display prompts are discontinued, and normal operation resumes.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
