Designed system measurement mechanism (as shown in Figure 2) of the present invention is employing two laser sensors 2, the mode of support is utilized to be fixedly mounted on lift car 1 top, measure the gauge 4 (transverse distance is equivalent to the X-axis of coordinate) of both sides respectively; In the vertical direction, utilize the mode of support to fixedly mount a laser range sensor 3 at lift car 1 top, record the lift car gauge value (fore-and-aft distance is equivalent to the Y-axis of coordinate) of each squareness.This device can facilitate the data value and vertical angle value that show elevator gauge in real time like this, can identify the non-compliant particular location of elevator gauge (by X-axis, Y-axis coordinate points is set up) very soon simultaneously.
The core of lower computer laser distance measuring system is micro controller system, complete that laser break-make controls by it, all hardware information monitoring in each squareness and corresponding gauge data sampling thereof and process, cell pressure and system, interval time of measurement arranged, setting that idle pulley or hardware debug mode measure wait time, with the multiple function such as upper computer data communication.
As shown in Figure 3, the initialization of main program primary responsibility completion system, and accept the data of sending from serial ports, carries out judging according to the content of data, processes, the work such as storage the diagram of circuit of lower computer system main program.After chip microcontroller initialization, from serial ports buffer area, extract desired data, analyzing and processing data, call sub-function module according to demand to perform corresponding function.
3, lower computer system Initializing Designing Program scheme
In the initialization procedure of lower computer system, generally need setting and timer, interruption, special function register that serial ports is relevant, set the initial condition of each I/O mouth, to needing the register of initialize to carry out initialize in internal memory, opening and interrupting allowing, starting timer, beginning main program cycle.
Before surveying work carries out, initialization is carried out to many parameters of measurement operation, as measurement pattern sets to 0, serial ports 1 switching mark position 0, the reception character count of each laser sets to 0, measure failure flags position 0, it is 3s that long distance laser range sensor restarts wait time, measures fail count and sets to 0.
The initialization design of serial port: in the communication of native system, serial port 1 and serial port 2 all need to be used to, the register that needs used mainly contains: Serial Port Control register SCON, serial port buffer register SUBF, background register AUXR, Timer Controlling register TCON, and Timer/Counter mode control register TMOD.
The initialization design of timer 1: timer 2 is used to the Baud rate generator of serial port 1 and serial port 2, timer 1 is then mainly used to the timing function realizing a 10ms, is convenient to arrange Measuring Time spacing, measure wait time equal time amount.Be 12T pattern by timer 1 clock setting in the design, therefore need T1x12 reset.
4, the data acquisition of lower computer system and transmission program design plan
In lower computer system, micro controller system realizes communicating with three lasers by MAX485, gather the gauge data measured and squareness data, each laser data information has its respective data format, and micro controller system can be converted into ASCII character form by unified for these data.In addition, choose P1.3/ADC3 mouth as A/D switching channel for measuring the information of voltage of battery, and it is equally also converted into ASCII character form.After data collection task completes, by MAX232 chip, send it in MCGS configuration software, by the unified process computing carrying out data of upper computer, and by result display on the touchscreen.

In measurement process, system is mainly in Three models: idle pulley, measurement pattern and hardware debug mode.Lower computer needs the main information sent upper computer to comprise all hardware information of battery voltage information, distance measurement information and measuring system, and the take off data of all lasers is all converted into ASCII character form to be sent to through serial port 2 from micro controller system that MCGS configuration software is unified carries out data processing.Its concrete program flow diagram as shown in Figure 4.As micro controller system receives the end mark of data cached group from serial ports 2 after program starts, then control survey laser sensor is opened and is measured, if do not receive the end mark of buffer memory array in this serial ports 2, then auto-returned principal function, when interval time of measurement reaches, then corresponding reading battery voltage information, in micro controller system, this signal is converted to 16 ary codes forms and sends from serial ports 2 by A/D conversion, the information that further reading 3 laser sensors are measured, the 16 ary codes forms that are converted into send from serial ports 2, serial ports 2 sends end mark to master system, open timer 1, remove serial ports 1 buffer memory array, return the transmission that principal function completes information.
5, master system software design scheme
In the present invention, select MCGS configuration software to carry out engineering design, for the platform that component safety and stability, rapidity and an accuracy have both, allow operator to process easily and manage in real time and historical data, realize elevator gauge data science is reasonably analyzed.When carrying out the engineering design of upper computer, the angle more needing to stand in user is to carry out making rational planning for of interface and operation.Distance sum between the distance of two laser range sensor 2 sounding rod end faces and two sensors to respective respective carter 4, the difference of predetermined gauge when installing with elevator, the required gauge deviation measured that Here it is.Therefore the processing sequence of data is:
1) two laser sensors 2 can be uploaded to upper computer by lower computer to the distance of track 4 and perpendicularity after data transfer.
2) staff measures and typing bench mark track space, generates the spacing d between laser range sensor two sounding rod end faces by the automatic computing of MCGS configuration software
0,
3) staff can select manual measurement pattern or automatic measurement pattern voluntarily, and indicates measuring sequence number.
4) enter elevator gauge and measure real time data interface, MCGS configuration software backstage is corresponding according to dynamic elevator gauge d=d
1× 2+d
0; Itself and elevator is installed time the difference of predetermined gauge dx be exactly the required gauge deviation delta d=d-dx measured, computing draws elevator gauge d, squareness distance h and elevator gauge deviation delta d data, and in display screen interface display, staff can check and preserve data.
5) measure terminate after enter take off data interface, have " closedown laser ", " derivation take off data ", " returning " three operation available below interface.If select " derivation take off data " option, staff can edit the file name of export, and data file is exported to the form of excel form in the USB flash disk be connected with USB interface and go.
Upper computer man-machine interface operating process of the present invention as shown in Figure 5.Namely user enters user's login interface after opening system, namely test program initialization interface is entered into by the mode inputting username and password, open laser sensor, initialization interface comprises three windows, system hardware messagewindow, checks historical data window and newly-built measurement gauge action pane.System hardware messagewindow can consult the information such as corresponding ardware model number, working parameter in this system; Check historical data window, the related data of the pre-test that can recall, the position of guide rail gauge deviation can be inquired about, be convenient to find maintenance point; Newly-built measurement gauge action pane can carry out new measurement once, after entering this window, the gauge bench mark that will measure need be set, select the pattern measured further as required and carry out the setting of corresponding sequence number, measure afterwards, the information of measurement after treatment, finally show that guide rail gauge deviation and squareness also show on a display screen, preserve these data simultaneously, then enter into take off data and derive window.The operation such as derivation, copy of data can be carried out by this window.
