Description

Technical Field

[0001] The present invention relates to an elevator safety monitoring and intelligent alarm system, and in particular to an elevator safety monitoring and intelligent alarm system applied in the elevator field. Background Art

[0002] Existing elevators have made significant progress in safety monitoring and intelligent alarm. For example, by installing sensors and monitoring equipment, real-time monitoring of various elevator operating parameters can be achieved, including elevator speed, load, door system, track vibration, elevator position, etc. Elevator Internet of Things technology integrates elevator data sensors, video monitoring, fault alarm system and other information into the management platform or software through wired or wireless protocols. The above technologies realize remote monitoring, automatic alarm, remote control, diagnostic maintenance, data mining and other functions of elevators.

[0003] These systems can detect abnormal situations in time and ensure the normal operation of the elevator by automatically alarming or taking corresponding safety measures.

[0004] In order to solve the problem of timely and accurate elevator alarms, a certain elevator in the market uses a voice recognition alarm information design, which has a certain market share.

[0005] The specification of Chinese invention patent CN113879931B discloses a method for monitoring elevator safety. A sound receiving component is provided in the elevator, and the method includes the following steps: the sound receiving component monitors the elevator car in real time and outputs the initial audio information; pre-screens the initial audio information to obtain the language audio information; extracts the call for help language from the language audio information; and triggers the safety alarm according to the call for help language extraction result. By using the word order classification extraction, keyword recognition and modal particle re-screening recognition operations in conjunction with the sound receiving component provided in the elevator, the call for help of the person trapped in the elevator is recognized and the alarm is triggered accordingly, which solves the problem that when the interactive alarm device in the elevator is damaged, or the person trapped in the elevator is an elderly person or a child who does not know how to use the interactive alarm device in the elevator, the elevator system cannot recognize the person's call for help, which causes a great safety hazard.

[0006] Existing elevators lack real-time, accurate data acquisition and feedback systems, making it difficult to capture changes in the elevator's operating status in a timely manner. In addition, safety protection measures are not in place, and the lack of necessary emergency facilities also limits the timely handling of accidents. These defects need to be addressed urgently to ensure the safe operation of elevators. Summary of the invention

[0008] In order to solve the above problems, the present invention provides an elevator safety monitoring and intelligent alarm system, including a device end and a system end, the device end includes an elevator shaft and an elevator body, a traction device matching the elevator body is installed on the top of the elevator shaft, an internal monitoring unit is installed in the elevator body, and a plurality of distributed protection beams corresponding to the floor positions are installed in the elevator shaft; a voice sensor, an acceleration sensor, an environmental monitoring sensor and a communication module are arranged in the internal monitoring unit;

[0009] A bottom beam is installed at the bottom of the elevator body, and a pair of damping plates matching the distributed protection beams are installed at the side ends of the bottom beam and the elevator body;

[0010] The side end of the distributed protection beam is slidably connected with a buffer beam, and a plurality of cylinders are connected between the buffer beam and the distributed protection beam. The buffer beam includes a main beam, and an upper protection plate and a side protection plate are respectively provided at the upper end and the side end of the main beam; buffer columns are connected between the upper protection plate and the side protection plate and the main beam;

[0011] There are multiple through holes on the side guard plate, a laser transmitter matching the position of the through holes is installed on the outer wall of the main beam, a laser receiver matching the laser transmitter is installed on the bottom beam, and the laser receiver is connected to the internal monitoring unit signal;

[0012] The system end includes a data processing terminal connected to the elevator body and multiple distributed protection beams, and the data processing terminal is provided with a monitoring module, a data processing module, a control module, an alarm module and an equipment management module;

[0013] The data processing module is used to analyze the monitoring data of the internal monitoring department and the pre-calculation of the speed of each point when the elevator is displaced; the monitoring data includes voice information and environmental parameters inside the elevator; the data processing terminal determines whether the operation of the elevator body is abnormal based on the monitoring data; the control module is provided with an auxiliary deceleration mode, a buffer mode and an auxiliary parking mode corresponding to the distributed protection beam.

[0014] In the above-mentioned elevator safety monitoring and intelligent alarm system, it is convenient to monitor the elevator operation status through the internal monitoring unit and give an alarm in time, and it is easy to coordinate the distributed protection beams to protect the elevator.

[0015] As a further improvement of the present application, two guide cavities are opened in the main beam, the buffer column includes a fixed column embedded in the main beam, a piston column is inserted in the fixed column, a buffer spring is installed at the bottom of the piston column, and an air pump for inflating the guide cavity is embedded in the elevator shaft.

DETAILED DESCRIPTION

[0036] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0037] The first implementation method:

[0038] Figure 1-6 An elevator safety monitoring and intelligent alarm system is shown, comprising an equipment end and a system end, wherein the equipment end comprises an elevator shaft and an elevator body, a traction device matching the elevator body is installed on the top of the elevator shaft, a guide rail is installed in the elevator shaft, and a guide slider matching the guide rail is installed on the outer wall of the elevator body; an internal monitoring unit 1 is installed in the elevator body, and a plurality of distributed protection beams 2 corresponding to the floor positions are installed in the elevator shaft;

[0039] The internal monitoring unit 1 is provided with a voice sensor, an acceleration sensor, an environmental monitoring sensor and a communication module; the internal monitoring unit 1 is used to collect environmental parameter information and voice information of personnel asking for help in the elevator, and the communication module is used to upload the collected data to the system end;

[0040] A bottom beam 11 is installed at the bottom of the elevator body, and a pair of damping plates 12 matching the distributed protection beam 2 are installed at the bottom beam 11 and the side ends of the elevator body;

[0041] The side end of the distributed protection beam 2 is slidably connected with a buffer beam 3, and a plurality of cylinders 21 are connected between the buffer beam 3 and the distributed protection beam 2. The buffer beam 3 includes a main beam 31, and an upper protection plate 32 and a side protection plate 33 are respectively provided at the upper end and the side end of the main beam 31; a buffer column 34 is connected between the upper protection plate 32 and the side protection plate 33 and the main beam 31;

[0042] A plurality of through holes are provided on the side protection plate 33, a laser transmitter matching the position of the through holes is installed on the outer wall of the main beam 31, a laser receiver matching the laser transmitter is installed on the bottom beam 11, and the laser receiver is connected to the internal monitoring unit 1 by signal; a protection frame 4 is connected to the lower end of the buffer beam 3; when the laser receiver is aligned with the laser transmitter for more than a set time, the elevator is judged to be stable at the stop; when the elevator passes the laser transmitter, the alignment time of the laser transmitter and the laser receiver can be used to assist in judging the moving speed of the elevator; when the elevator is stopped, the number of intermittent alignments between the laser receiver and the laser receiver within a set time can be used to assist in judging the vibration state of the elevator;

[0043] The system end includes a data processing terminal connected to the elevator body and multiple distributed protection beams 2, and the data processing terminal is provided with a monitoring module, a data processing module, a control module, an alarm module and an equipment management module;

[0044] The data processing module is used to analyze the monitoring data of the internal monitoring unit 1 and the pre-calculation of the speed of each point when the elevator moves; the monitoring data includes voice information and environmental parameters in the elevator. The data processing module recognizes the voice information and, if it recognizes a person's distress message, it also determines that the elevator is operating abnormally;

[0045] The control module is provided with an auxiliary deceleration mode, a buffer mode and an auxiliary parking mode corresponding to the distributed protection beam 2;

[0046] In the auxiliary deceleration mode, the buffer beam 3 moves outward by a distance L1 to hold the damping plate 12 at the side end of the elevator body tightly;

[0047] In the buffer mode, the buffer beam 3 is displaced outward by a distance L2 to provide buffering through the upper protection plate 32 at the lower side of the elevator body;

[0048] In the auxiliary parking mode, the buffer beam 3 is displaced outward by a distance L3, so that the lower side of the elevator body is buffered and protected by the upper protective plate 32, and the side protective plate 33 is used to hold the damping plate tightly to stabilize the elevator body.

[0049] This embodiment can monitor the operation status of the elevator body, such as acceleration, environmental parameters, etc., in real time through the arrangement of the internal monitoring unit 1 and the distributed protection beam 2, so as to give an alarm in time when the elevator is operating abnormally;

[0050] The distributed protection beam 2 adopts the design of the buffer beam 3 and the upper protection plate 32 and the side protection plate 33 thereon to form a multi-directional buffer protection, so as to slow down or buffer the elevator according to the type of abnormal operation state of the elevator, and effectively reduce the damage caused by the abnormal operation of the elevator.

[0051] When an abnormality occurs in the elevator itself, the system can intelligently judge and trigger the corresponding deceleration, buffering or auxiliary parking mode to reduce the possibility of accidents and the extent of damage.

[0052] The data processing terminal on the system side can analyze the monitoring data of the elevator in real time. Once an abnormality is found, the alarm module is immediately triggered and the distributed protection beam 2 is controlled to start the corresponding working mode to deal with the abnormal situation.

[0053] Second implementation method:

[0054] Figure 1-9 As shown, two guide cavities 35 are opened in the main beam 31, and the buffer column 34 includes a fixed column embedded in the main beam 31, a piston column is inserted in the fixed column, the piston column and the fixed column are relatively sealed and slide relative to each other, a buffer spring is installed at the bottom of the piston column, and an air pump for inflating the guide cavity 35 is embedded in the elevator shaft.

[0055] The protection frame 4 includes a positioning beam 41 and a plurality of buffer inserts 42. A flow guide channel is provided in the positioning beam 41 and is fixedly connected to the inner wall of the elevator shaft.

[0056] One end of the buffer insert 42 located outside the buffer beam 3 is connected to a shunt block 43, a coordination tube 44 is provided between the plurality of shunt blocks 43, an electromagnetic three-way valve is provided in the shunt block 43, the input end of the electromagnetic three-way valve is communicated with the coordination tube 44, and the two output ends are respectively communicated with the two guide chambers 35; a plurality of telescopic buffer arms 45 are connected between the coordination tube 44 and the positioning beam 41, and a buffer airbag communicated with the guide channel is provided in the telescopic buffer arm 45; the output end of the air pump is connected with the positioning beam 41 and the coordination tube 44;

[0057] When the distributed protection beam 2 detects that the acceleration of the elevator body exceeds the set speed, the distributed protection beam 2 triggers the auxiliary deceleration mode. When the auxiliary deceleration mode is working: all the distributed protection beams 2 in the running direction of the elevator position are selected, and the cylinder 21 drives the buffer beam 3 to move outward a set distance L1, so that the side protection plate 33 is close to the damping plate 12. When the acceleration of the elevator body is reduced to within the set value range, the distributed protection beam 2 at a set distance from the elevator body in the running direction of the elevator body is selected and set to the buffer mode.

[0058] When the data processing module determines that the elevator body is operating abnormally, the buffer mode is triggered. In the buffer mode, a distributed protection beam 2 at an appropriate distance from the elevator is selected and the floor matching it is set as the arrival floor. Then, the cylinder 21 at the position of the distributed protection beam 2 is controlled to drive the buffer beam 3 to move outward a set distance L3, so that the upper protection plate 32 is located on the lower side of the elevator body. At this time, an air pump is used to inflate the telescopic buffer arm 45 and the buffer column 34 at the upper protection plate 32, and at the same time, the elevator body is controlled to decelerate; the airbags in the buffer column 34 and the telescopic buffer arm 45 are inflated to improve the buffer protection effect.

[0059] The data processing module triggers the auxiliary parking mode when it determines that the elevator body is unstable at the stop. When the displacement or vibration frequency of the elevator body when parked exceeds the set value range, it is determined that the parking is unstable. When the auxiliary parking mode is working, the cylinder 21 drives the buffer beam 3 to move outward a set distance L3, and then uses an air pump to inflate the buffer column 34 at the upper protective plate 32 and the side protective plate 33 and the coordinated pipe 44, so that the side protective plate 33 holds the damping plate 12 tightly.

[0060] After the elevator body selects the arrival floor, the distributed protection beam 2 at the arrival floor position starts the buffer mode. After the elevator body arrives and the monitoring data is normal, the distributed protection beam 2 is reset. If the monitoring data is abnormal, it switches to the auxiliary parking mode.

[0061] The data processing terminal calculates the speed of the elevator body when it passes through each distributed protection beam 2 according to the running distance of the elevator body; when the speed measured at any distributed protection beam 2 during the movement of the elevator does not match the calculated speed, it is judged that the elevator body is running abnormally.

[0062] This embodiment enables the data processing terminal to accurately analyze the monitoring data of the elevator. According to the different operating states of the elevator body, the system can intelligently switch the auxiliary deceleration mode, buffer mode and auxiliary parking mode to provide all-round protection and emergency treatment; such as selecting the appropriate distributed protection beam 2 for deceleration, buffering or auxiliary parking operation to ensure the safety and reliability of the elevator operation, and the air pump works in coordination in each working mode to further improve the buffer protection effect.

[0063] When the data processing module determines that the elevator body is operating abnormally, it can automatically select the arrival floor and start the buffer mode to make full preparations for the elevator to stop smoothly.

[0064] In summary, the system of this solution highly integrates the elevator's safety monitoring, data processing and analysis, and alarm functions in order to analyze the elevator's abnormal operation, and coordinately distributes the protective beam 2 to respond to different elevator abnormal operation states, thereby realizing elevator safety monitoring, intelligent alarm, and safety protection.

[0065] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
