Description

TECHNICAL FIELD

[0001] The present application relates to elevator information collection and processing technology, in particular to elevator floor information automatic identification and display control. BACKGROUND

[0002] The existing elevator floor display, in-car advertising machine, etc. generally obtains floor data from the elevator display interface and then displays, such as the elevator abnormal condition monitoring system disclosed in CN107381265A. When an abnormality occurs during elevator operation, the floor output from the display interface of the elevator control panel is a non-numeric character. The floor data cannot be read from the display interface, so the elevator advertising machine and the floor display do not display the floor at this time or keep the last floor number unchanged. When the elevator resumes normal floor data output, the elevator has often moved many floors or has reached the 1st floor. Therefore, from the user's point of view, from the time the elevator abnormality occurs to the time the elevator returns to normal display, the elevator floor display directly jumps from a high floor to the bottom floor or the top floor. As a result, the user may misunderstand and complain that the elevator directly falls from a high floor to the bottom floor or rushes to the top floor, causing psychological panic among elevator passengers. SUMMARY

[0003] The present application relates to elevator information collection and processing technology, in particular to elevator floor information automatic identification and display control.

[0004] The system comprises a main controller (MCU) and a height sensor. The main controller (MCU) contains a data storage device for permanently storing data. The height sensor is electrically connected to the main controller (MCU). The height sensor is used to collect the height of the elevator car and feed the height data to the main controller (MCU). The data collected and processed by the main controller (MCU) includes a display data collection unit, a data analysis unit, a height information collection unit, a floor height recording unit, a current floor acquisition unit, a new data generation unit, and a data output switching unit.

[0005] Preferably, the main controller (MCU) is connected to a memory, a clock chip, an indicator light, an LED digital tube, a key, a serial interface, and a power supply.

[0006] Preferably, the main controller (MCU) is electrically connected to the original hardware module of the elevator, i.e., the elevator control panel and the elevator information display module.

[0007] Preferably, the main controller (MCU) is a PIC chip from MicroChip. The EEPROM of the chip is a data storage device for permanently storing data.

[0008] Preferably, the step of collecting and processing data by the main controller (MCU) comprises the following steps:

[0009] Step one, the display data collection unit collects data on the elevator control panel and transmits the collected control panel data to the data switching unit and the data analysis unit;

[0010] Step two, the height information collection unit collects height data from the height sensor and transmits the collected height data to the floor height recording unit and the current floor acquisition unit;

[0011] Step three, the data analysis unit parses the collected control panel data according to the protocol to obtain the data content, acquires the current floor data, elevator abnormal state data and related elevator operation data from the data content, transmits the floor data to the floor height recording unit, sends the abnormal state data to the data output switching unit, and sends all parsed data to the new data generation unit;

[0012] Step four, the floor height recording unit matches and stores the floor data obtained from the height data collection unit and the floor height data obtained from the height information collection unit after operation processing in the data storage, and provides the stored floor data, height data, running speed, running direction and related elevator operation data to the outside;

[0013] Step five, the current floor acquisition unit reads out the matched floor and height data from the floor height recording unit according to the received floor height data, obtains the current floor data through operation search, and transmits the floor data to the new data generation unit;

[0014] Step six, the new data generation unit fills the floor data received from the current floor acquisition unit into the data obtained from the data analysis unit to generate new data with floor information, so that when the elevator is abnormal, even if the data output by the elevator control panel does not have floor data, the data generated by the new data generation unit also has accurate floor data;

[0015] Step seven, the data output switching unit judges the elevator abnormal state obtained from the data analysis unit;

[0016] Step eight, if there is no abnormality, the original elevator data obtained from the display data collection unit is directly sent to the elevator information module; if there is an abnormality, the newly generated elevator data obtained from the new data generation unit is sent to the elevator information module.

[0017] In summary, the application has the following beneficial effects: when the elevator is abnormal, the data output by the elevator no longer contains floor information, but the floor data can still be accurately output to the elevator display, avoiding the misunderstanding that the elevator falls from the high floor to the bottom floor due to the floor display jumping when the elevator is abnormal, reducing passenger panic and complaints.
