Detailed Description

The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and it should be understood that the embodiments of the invention described herein are merely illustrative and are not intended to limit the present invention.

Examples

The specific implementation process is as follows:

the camera A/linear distance measuring sensor 5 is used in combination, collected data enable the opening and closing state of the elevator door to be detected easily and accurately to be cm, and the problem that the original elevator door can only detect the opening state and the closing state is thoroughly solved. Meanwhile, the blocking object placed on the elevator door manually can be judged visually, and the possibility of false alarm is eliminated.

After the elevator door is opened, the tablet personal computer starts to wake up from dormancy, all sensors start to work, the high-definition camera A/linear distance measuring sensor 5 starts to measure the opening and closing state of the elevator door and the amplitude value of the opened door, the laser speed measuring sensor 4, the three-axis acceleration sensor and the temperature sensor in the tablet personal computer 3 start to acquire the operation initial value of the elevator, the high-definition camera A, B starts to acquire images, when the light of the elevator car is insufficient, the illumination is automatically started,

the tablet personal computer 3 starts to operate and structurally analyze the internal condition of the lift car, the condition of passengers, the condition of carried articles and the opening and closing condition of the lift door, and if the door is not opened in place or is opened and closed repeatedly under the condition of no shielding, the alarm of 'abnormal lift door' is sent out by uploading. If the elevator car starts to move under the condition that the elevator door is not completely closed, an alarm of 'out of control of elevator' is sent out in an uploading mode. Under the normal condition that the elevator door is opened, along with the entering of passengers and carried articles, the millimeter-level detection precision of the laser speed measurement sensor can detect that the elevator car moves slowly, so that the flat computer sends an alarm of 'car sliding', and people can evacuate through voice prompt.

After the elevator door is normally closed, the tablet personal computer 3 can accurately judge whether the elevator ascends or descends according to data scanned at a high speed by the laser speed measuring sensor 4, can judge the magnitude of the dragging force according to the calculation of the time from zero acceleration to constant speed and from constant speed deceleration to zero of the elevator, can estimate the abrasion condition of the steel rope, and uploads and sends out a steel rope fault alarm if the abrasion condition exceeds an empirical value. The panel computer 3 is according to the car operation in-process, when the unusual vibrations that triaxial acceleration sensor detected with rock, through high definition digtal camera A \ B, get rid of artificial influence such as beating, fighting, goods fall, save triaxial acceleration sensor detected value immediately, the current velocity value that laser speed sensor 4 returned and the position value of unusual vibrations point, if triaxial acceleration sensor detected value exceeds empirical data value, upload and send "guide rail trouble" warning to accurately mark out trouble position point, make things convenient for the dimension maintainer to overhaul. If the detected value of the triaxial acceleration sensor does not exceed the empirical data value but reaches a secondary numerical value according to the empirical data, uploading and sending out a guide rail abnormity early warning, recording and establishing a maintenance detection catalogue, and detecting the next time of elevator maintenance.

When the elevator is in operation, the tablet personal computer 3 carries out structured processing on image data of the high-definition camera A/B and voice data acquired by the digital audio sensor, can acquire contour physical signs of passengers, and can also carry out face recognition and comparison, gait recognition and comparison and voiceprint recognition and comparison under the special requirements of national functional departments such as public security, judicial and supervision. The tablet personal computer 3 can judge whether the passenger has inappropriate behaviors such as jumping and smoking by calculating the outline, the appearance and the physical signs of the passenger, and can start corresponding warm voice to inform and stop. If the passengers fight violently, the alarm of 'abnormal passengers' is sent out in an uploading mode, and the passengers are warned through the strict words of voice. If the passenger falls down, the inquiry mode can be started, and if the passenger does not fall down, the voice prompt is warm. If the falling passenger can not answer or other passengers answer that rescue is needed, an alarm of passenger injury is sent up to inform relevant departments of immediate rescue, and a remote two-way visual intercom can be started to guide other passengers in the lift car to provide emergency treatment. And the panel computer 3 judges that the elevator speed is zero according to the detection value of the three-axis acceleration sensor and the data of the laser speed measuring sensor 4, immediately records the position data value of the current elevator car, uploads and sends out an early warning of elevator car floor fault if the data value exceeds an early warning experience value, records in and establishes a maintenance detection directory, and detects the elevator next time of maintenance. If the data value exceeds the range of the experience value, a 'car floor fault' alarm is sent out in an uploading mode, if the data value exceeds the range of the experience value, the elevator door is opened, a 'car floor blocking' alarm is sent out in an uploading mode, maintenance personnel are informed of emergency rescue, meanwhile, voice warm prompt is given, passengers are required to be pacified to wait for rescue on the spot, and the passengers do not leave forcibly. If the elevator door is not opened at this time, an alarm of 'passengers are trapped' is sent out in an uploading mode, maintenance personnel are informed of emergency rescue, two-way talkback is started, and the trapped people are subjected to psychological pacifying.

When the elevator car runs up and down, if the speed exceeds the preset maximum value at any time, the alarm of 'car overspeed' is sent out in an uploading mode. If the acceleration time is too long or the normal speed value is not reached all the time, an alarm of 'car stall' is sent out in an uploading mode. If the acceleration of the elevator car is too large, the acceleration reaches the gravity acceleration value and continues, and then the alarm of 'car falling' is sent out in an uploading mode. If the elevator car does not decelerate when running to the highest deceleration point or the deceleration time is too long, the elevator car passes the highest point, and an alarm of 'car rushing to the top' is sent out by uploading. If the elevator car does not decelerate when running to the lowest deceleration point or the deceleration time is too long, the elevator car passes the lowest point, and then an alarm of 'car squat bottom' is sent out. If the elevator car runs, the deceleration time is too long, or the deceleration is not stable, large or small, the early warning of 'band-type brake abnormity' is uploaded and sent out, and if the early warning is frequent, the alarm is upgraded to 'band-type brake fault' for warning.

In case the elevator reports to the police, the high in the clouds can be very first time with alarm information propelling movement for the maintenance personnel, also can record the time that the maintenance personnel arrived the scene simultaneously. And under the condition of no fault alarm, maintaining the elevator by adopting a timing maintenance mode, and uploading and sending a maintenance overtime alarm if the maintenance personnel does not perform maintenance operation after the maintenance period exceeds the normal maintenance period.

The maintenance process is as follows: in a normal maintenance period, a maintenance worker enters the elevator, the mobile phone is connected with the tablet personal computer through WIFI, after registration and authentication are carried out, the tablet personal computer 3 displays a directory needing maintenance and an operation guiding step for detecting each directory, the maintenance worker can complete the detection of the directory after strictly operating according to the guiding, and the tablet personal computer 3 clears the maintenance cycle timing. If the operation is not performed as required, the detection of the directory cannot be completed. Therefore, the standardization of maintenance is realized, and the maintenance quality is ensured.

When all the alarm data are uploaded, the unique identification information of each elevator is added according to the block chain principle, and cloud identification is facilitated.

When the elevator runs to the correct position and stops, the door is opened normally to the correct position, the door is closed normally to the correct position after the personnel leave, and after 20 seconds of delay, the tablet personal computer 3 enters a low-power-consumption dormant state to wait for starting the working cycle next time. When the tablet computer 3 enters a sleep state, the report data is sent to the cloud control center at regular time. If the cloud does not receive the reported data of the tablet computer 3 regularly, the fault is marked as 'child lost connection'. And if the reported data received by the cloud end is lost, marking the reported data as a fault of 'network drop at the child end'.

The above embodiments describe in detail the method of generating the warning and alarm signals by the step judgment operation. The early warning and the alarm signal name of mark in the above can not be used for limiting the utility model discloses a scope of protection. Operation method is judged based on the step in the above, and the early warning and the alarm information that reachs all belong to the utility model discloses a protection scope.
