Detailed Description
An elevator fault monitoring system provided by an embodiment of the present invention is shown in fig. 1, and fig. 1 is a structural block diagram of an elevator fault monitoring system provided by an embodiment of the present invention.
An elevator fault monitoring system, the system comprising:
a door magnetic state monitor 11 for monitoring the open/close state of the car door and generating a car door state change signal;
the elevator running state monitor 12 is used for acquiring the current running state of the car body and generating a car body motion signal;
and the processor 13 is used for receiving the car door state change signal generated by the door magnetic state monitor and determining whether the elevator has a fault or not based on the car door state change signal and the car body movement signal.
The door magnetic state monitor 11 in this embodiment is a device independent from the car door, that is, the door magnetic state monitor can still be used normally when being taken down independently, thus facilitating installation, disassembly and maintenance. The door magnetic state monitor 11 can be arranged on the side where the car doors will contact when the two car doors are closed, and the door magnetic state monitor 11 can be a distance sensor, or a proximity sensor, or a combination of magnetic devices and reed pipes. The magnetic state monitor 11 in the embodiment of the present invention includes, but is not limited to, the above-mentioned devices and their combinations.
When the door magnetic state monitor 11 is a distance sensor, the distance sensor determines whether the two car doors are in a closed state by emitting infrared rays or light or ultrasonic waves to an object and the time difference reflected by the object, and when the measured time difference is smaller, the two doors are in the closed state; when the measured time difference is larger and larger, the two doors are in an opening state. Wherein, the closing state in the embodiment of the present invention means: the car door is in the process of closing or has finished closing the state of the car door; being in the open state means: the car door is in the process of opening or has fully opened the state of the car door.
When the door magnetic state monitor 11 is a proximity sensor, the proximity sensor can monitor the movement of the other door, thereby determining whether the car door is in a closed or open state.
When the door magnetic state monitor 11 is a combination of a magnetic device and a reed switch, if the reed switch is conducted under the action of a magnetic field generated by the magnetic device, it indicates that the distance between the magnetic device and the reed switch is reduced at the moment, and it is determined that the car door is closed or closed; if the reed switch is disconnected under the action of the magnetic field generated by the magnetic device, the distance between the magnetic device and the reed switch is increased, and the car door is determined to be opened in the process or be completely opened at the moment.
An elevator operating condition monitor 12 includes an acceleration sensor by which the state of motion of the elevator is monitored. The elevator running state monitor 12 is arranged in the carriage body, is independent of the carriage body, and can be fixed on the wall of the carriage body through an adhesive or magnetic device or fixed on the top of the carriage body. The design avoids the situation that the device for monitoring the running state of the elevator is embedded into the elevator in the prior art and is mixed with the circuit of the elevator, and the running state monitor 12 of the elevator is independently arranged in the car body, so that the elevator running state monitor is convenient to mount and dismount and is convenient to maintain.
And the processor 13 is arranged on the elevator running state monitor 12, determines whether the elevator has a fault or not according to the received car door state change signal generated by the door magnetic state monitor 11 and the car body movement signal, and generates a fault signal.
According to the embodiment of the invention, the door magnetic state monitor 11 and the elevator running state monitor 12 are arranged independently of the car door and the car body of the elevator instead of being embedded into the car body in an embedded manner, so that the devices can be simply and conveniently assembled, disassembled and maintained, and the problem of complicated operation when the devices are embedded in the embedded manner due to the fact that elevator manufacturers are numerous and the arranged interfaces are different is also solved.
Fig. 2 shows a magnetic state monitor 11, where fig. 2 is a block diagram of a magnetic state monitor 11 combining a magnetic device and a reed switch.
The door magnetic state monitor 11 comprises a magnetic device 111 and a reed pipe 112 which are respectively arranged on one sides which can be contacted when the two car doors are closed.
The door magnetic state monitor 11 is used for determining that the car door is in a closed state when the reed switch 112 is in a conducting state; and also for determining that the elevator car door is in an open state when the reed switch 112 is in an open state.
As shown in fig. 3, fig. 3 is a structural diagram of a door magnetic state monitor 11 according to an embodiment of the present invention. The magnetic device 111 and the reed switch 112 may be placed at two points as in fig. 3. In practice, the positions of the door magnetic state monitor 11 include, but are not limited to, these two positions, and the origin in fig. 3 only represents the positions where the magnetic device 111 and the reed pipe 112 are placed, and does not represent the relative size relationship thereof.
The magnetic device 111 can be a magnet or other device capable of generating a magnetic field, and the reed pipe 112 and the magnetic device 111 are respectively arranged on the two car doors and can be arranged at the same height from the ground.
In fig. 3, when two doors are in a close state, the distance between the reed pipe 112 and the magnetic device 111 is close, the action of the magnetic field generated by the magnetic device 111 on the reed pipe 112 is enhanced, at this time, two reeds in the reed pipe 112 generate different polarities, when the magnetic force exceeds the elastic force of the reeds themselves, the two reeds attract and conduct a circuit, at this time, the processor 114 in the door magnetic state monitor 11 detects this condition, and thus it is determined that the two car doors are in a close state at this time, where the close state represents that the car doors are in a closing process or are completely closed.
When the two doors are in a separated state, the distance between the reed pipe 112 and the magnetic device 111 is pulled, the magnetic field generated by the magnetic device 111 has smaller and smaller effect on the reed pipe 112, when the magnetic effect on the two reeds in the reed pipe 112 is lower than the elastic force of the reeds, the two reeds can be separated, so that the circuit is disconnected, and the processor 114 in the door magnetic state monitor 11 detects the disconnection condition of the reed pipe, so as to determine that the two car doors are in an opened state at the moment, wherein the opened state represents that the car doors are in the opening process or are completely opened.
The door magnetic state monitor 11 is further configured to transmit the generated car door state change signal to the processor 13 through the bluetooth communication module 113.
The door magnetic state detector 11 will detect the car door state change signal of the car door through the processor 114 in fig. 2, and then will perform data interaction with the bluetooth communication module 121 of the elevator operation state monitor 12 in fig. 4 through the bluetooth communication module 113 shown in fig. 2, and will transmit the car door state change signal to the processor 13 of the elevator operation state monitor 12, and the processor 13 will make the judgment whether there is a fault in the elevator. Fig. 4 is a block diagram of an elevator operation status monitor according to an embodiment of the present invention.
As known to those skilled in the art, since the elevator is made of metal and belongs to a closed space, and the internal signals are weak in general, in the embodiment of the present invention, the door magnetic state monitor 11 and the elevator operating state monitor 12 perform data interaction through respective bluetooth communication modules, i.e., the bluetooth communication module 113 in fig. 2 and the bluetooth communication module 121 in fig. 4, so that in the case of poor signals, the door magnetic state monitor 11 can still transmit the car door state change signal to the processor 13 of the elevator operating state monitor 12.
In addition, the lithium battery 115 is arranged in the door magnetic state monitor 11 to supply power to the whole door magnetic state monitor 11, so that the door magnetic state monitor 11 can continuously work under the condition that the door magnetic state monitor is not electrically connected with a car door or a carriage body of the elevator, and flexible installation, disassembly and maintenance of the door magnetic state monitor 11 are further ensured.
The processor 13 is specifically configured to determine that the elevator has a fault when the car door state change signal indicates that the car door is in the open state, the motion signal indicates that the car body does not stop moving within a first preset time, or the motion signal indicates that the car body is in the stationary state, and the acceleration of the car body is suddenly increased and decreased, or the motion signal indicates that the car body is in the stationary state for a time period shorter than a second preset time period.
In fig. 4, the elevator running state monitor 12 further includes an acceleration sensor 122 and a timer 123, the acceleration sensor 122 detects the acceleration of the current running of the elevator, the timer 123 records the time, the acceleration and the time are transmitted to the processor 13, and the processor 13 can calculate the speed of the current movement according to the acceleration and the time.
When the state change signal of the car door generated by the door magnetism state monitor 11 indicates that the car door is in an open state, if the motion signal of the elevator operation state monitor 12 indicates that the car door does not stop moving within a first preset time, for example, when the door magnetism state monitor 11 is a combination of the magnetic device 111 and the reed switch 112, the conductive signal of the reed switch 112 is switched from on to off during the opening process of the door, and indicates the process that the elevator door is opening, at this time, the car body of the elevator may not be completely stopped at a specified floor, and the operation needs to be continued, and the operation includes an upward movement toward a high floor or a downward movement toward a low floor. When the car door of the elevator is fully open, the elevator car, if still running, indicates that there is a malfunction in the elevator. The first preset time may be a time from the opening of the elevator car door to the complete stopping of the elevator, which is set by a person skilled in the art according to historical experience, or may be a time length from the beginning of the opening to the complete opening of the elevator car door, which is set by the person skilled in the art at the time of factory shipment.
Alternatively, when the motion signal of the elevator operation status monitor 12 indicates that the car of the elevator is in a stationary state, if the car suddenly has a large upward or downward acceleration, the passenger can feel that the elevator suddenly moves upward or downward for a small distance and stops, and then the elevator is also indicated to have a fault.
Or, when the time that the motion signal of the elevator operation state monitor 12 represents that the car body of the elevator is in the stationary state is less than a second preset time, which is a time period from the complete opening of the elevator door to the beginning of closing, a person skilled in the art can set the second preset time according to actual conditions, or set the value when the elevator leaves the factory. If the car door of the elevator is closed within the second preset time, the problem of the elevator is also shown.
Or the elevator is infrared sensing passenger, if the car door of the elevator senses that people enter or exit and the signal is no problem, if the car door of the elevator is closed, the elevator is in failure.
The fault detection method for the opening of the elevator car door provided by the embodiment of the invention comprises but is not limited to the methods.
The processor 13 is further configured to, when the car door state change signal indicates that the car door is in the closed state, indicate that the car body moves at a speed lower than a first preset speed or higher than a second preset speed, where the first preset speed is lower than the second preset speed, or indicate that the car body moves in one direction and suddenly moves in another direction, or indicate that the car body moves in one direction and the acceleration starts moving at a value exceeding the first preset acceleration, and determine that the elevator has a fault.
When the state change signal of the car door generated by the door magnetic state monitor 11 indicates that the car door is in a closed state, if the motion signal of the elevator operation state monitor 12 indicates that the car body of the elevator moves at a very low speed or at a very high speed, the elevator is indicated to have a fault.
Or, if the motion signal of the elevator running state monitor 12 indicates that the car of the elevator is moving upward/downward, the sudden acceleration is in the opposite direction, i.e. the elevator falls/goes upward for a certain distance, indicating that the elevator has a fault.
Or, if the motion signal of the elevator running state monitor 12 indicates that the car of the elevator is moving, and suddenly moves at a large acceleration, that is, the elevator suddenly accelerates, it also indicates that the elevator has a fault.
The method for detecting the fault when the door of the elevator car is closed provided by the embodiment of the invention comprises but is not limited to the methods.
The elevator running state monitor 12 further comprises a display screen 124; and the display screen 124 is used for displaying the current running state of the elevator.
As shown in fig. 4, the elevator operation status monitor 12 further includes a display screen, and when the elevator operation status monitor 12 is disposed on the elevator car wall, not only can an area be set to display the operation status of the elevator in real time, but also the display screen can be used for advertising, so that the value of the elevator operation status monitor 12 is maximized.
The elevator running state monitor 12 further comprises a communication module 125; the communication module 125 is configured to generate a fault signal when the processor determines that the elevator has a fault, and transmit the fault signal to the elevator monitoring cloud platform 50 through the gateway.
As shown in fig. 5, fig. 5 is a structural diagram of an elevator fault monitoring system according to an embodiment of the present invention. In fig. 5, when the processor determines that the elevator has a fault, the communication module 125 of the elevator operation status monitor 12 communicates with the gateway, in an embodiment of the present invention, the communication module 125 may be the LoRaWAN communication module in fig. 4, the gateway may be the LoRaWAN communication gateway 30 in fig. 5, the communication module 125 first communicates with the LoRaWAN communication gateway 30, and then the LoRaWAN communication gateway 30 transmits a fault signal to the elevator monitoring cloud platform 50 through the LoRaWAN network cloud platform 40 in fig. 5. And the transmission of the fault signal is completed through the whole process.
The gateway is arranged on the roof of the building where the elevator is located.
The LoRaWAN communication gateway 30 designed in the embodiment of the invention is arranged on the roof of a building where an elevator is located, and a small house can be arranged on the roof and is specially used for placing the communication gateway 30. As shown in fig. 5, a building includes several units, and the elevator of each unit finally transmits a fault signal to the elevator monitoring cloud platform 50 through the LoRaWAN communication gateway 30 on the roof. Therefore, unified management can be realized, resources are saved, and signal transmission is facilitated.
The elevator running state monitor 12 in the embodiment of the present invention further includes a lithium battery 126, which is specially used for providing electric quantity for all components of the elevator running state monitor 12, so as to ensure normal operation thereof, so that the elevator running state monitor 12 can continuously work without being electrically connected with the car door or the car body of the elevator, and further, flexible installation, disassembly and maintenance of the elevator running state monitor 12 are ensured.
The system further comprises a distance sensor 10; the distance sensor 10 is configured to monitor whether a distance difference exists between an actual stop position of the car body and a preset stop position of the car body after the car door is opened.
The distance sensor 10 may be disposed on the top of the elevator car or on the floor. When setting, an angle may be set so that infrared rays or ultrasonic waves or light emitted from the distance sensor 10 can be irradiated at an oblique angle.
Taking the distance sensor 10 disposed on the top of the elevator car body as an example, as shown in fig. 6, the distance sensor 10 emits infrared rays or ultrasonic waves or light to a certain extent, and when the elevator car door is opened, the infrared rays or the ultrasonic waves or the light are emitted to the normal ground b by the distance sensor 10, at this time, the distance sensor 10 records the time difference between the emitted signal and the received signal, and if the time difference is equal to the preset time difference, then, the position representing the actual stop of the elevator car body is not different from the preset position, that is, the elevator car body is at a horizontal position with the ground. The preset time difference may be measured through a plurality of experiments when the distance sensor 10 is placed by a person skilled in the art. Fig. 6 is a position diagram of a distance sensor according to an embodiment of the present invention.
When the elevator car door is opened, when the distance sensor 10 emits infrared rays or ultrasonic waves or light to a normal ground a, the time difference between the emitted signal and the received signal measured by the distance sensor 10 is smaller than the preset time difference, the elevator car body is lower than the ground, and the position representing the actual stop of the elevator car body is different from the preset stop position by the distance difference.
When the elevator car door is opened, when the distance sensor 10 emits infrared rays or ultrasonic waves or light to a normal ground c, the time difference between the emitted signal and the received signal measured by the distance sensor 10 is greater than the preset time difference, the elevator car body is higher than the ground, and the position representing the actual stop of the elevator car body and the preset stop position also have the distance difference.
The principle of the scheme of arranging the distance sensor 10 at the bottom of the car body is similar to that of the scheme of arranging the distance sensor at the top of the car body, and the same is true of the method for determining whether the distance difference exists between the actual stopping position and the preset position of the elevator car body.
In practical applications, a person skilled in the art can set different positions of the distance sensor 10 according to practical situations, as long as it can be measured whether the actual parking position of the car body is consistent with the preset parking position.
The processor 13 is further configured to determine that the elevator has a fault when the door magnetic state monitor 11 represents that the car door is opened, and the elevator operation state monitor 12 represents that the car body is stationary, and an actual position monitored by the distance sensor 10 is not equal to a preset position.
When the elevator car door is opened and the car body is stationary, the distance difference exists between the position where the car body is actually stopped and the preset stopping position represented by the distance sensor 10, namely the processor can also determine that the elevator has a fault when the bottom of the car body and the ground of the floor are not on the same horizontal plane.
According to the embodiment of the invention, the door magnetic state monitor 11 and the elevator running state monitor 12 are directly fixed on the car door or the car body wall through adhesion or magnetic materials, so that the door magnetic state monitor 11 and the elevator running state monitor 12 can be simply and conveniently installed, detached and maintained, the real-time performance and convenience for measuring whether the elevator has faults or not are further ensured, and the trouble of regularly arranging operation and maintenance personnel for maintenance is saved; the door magnetic state monitor 11 and the elevator running state monitor 12 are communicated through the Bluetooth module, so that the problem of poor signals in the elevator is avoided; the elevator fault signal is transmitted to the elevator monitoring cloud platform 50 through the LoRaWAN communication module 125 and the LoRaWAN gateway 30, so that the signal is effectively transmitted.
