Detailed description of the invention
Embodiment:
The utility model tester mainly comprises the main frame be located on escalator or moving sidewalk step plate and the trigger button box be located on escalator or moving sidewalk scram button 1, main frame comprises the micro controller system that model is 89E564RD, by the rotary encoder that signaling conversion circuit is attached thereto, and take turns the power wheel of coaxial setting with the rotary coding of rotary encoder, power wheel is by jacking system adjustment contact step, and nationality is by operating escalator or the drive of moving sidewalk group portion is lower and rotary coding takes turns synchronous axial system.Described rotary encoder is 10 coders, and rotary coding wheel is arranged on the flexible shaft of larger degree of freedom, so that adjustment during test, ensures that code wheel can be stablized, run exactly.Micro controller system is also connected with PT2272 infrared remote control receiving chip, power supply, operating control (keyboard), LCDs, mini-printer (model RD-DH32 chopping machine, the illustrious and influential Creative Technology Ltd. in Beijing produces) and combined aural and visual alarm; Be illustrated in figure 1 trigger button box constructional drawing.Trigger button box comprises PT2262 Infrared Remote-Control Sending chip 4 and the power supply of the scram button interlock be arranged on escalator or moving sidewalk power circuit, and linking between scram button and Infrared Remote-Control Sending chip 4 is realized by gang switch.Gang switch comprises one and to be electrically connected with Infrared Remote-Control Sending chip 4 and the contact switch 3 controlling its connecting and disconnecting of the circuit, also comprise the compressing tablet 2 that is fixed on the main portable bar of scram button 1, compressing tablet 2 is corresponding with the contact on contact switch 3, compressing tablet 2 is by scram button 1 dipping and heaving, when scram button 1 is pressed, compressing tablet 2 moves downward with the main portable bar of scram button 1, compresses the contact of contact switch 3, and Infrared Remote-Control Sending chip 4 is energized and transmits.PT2262 Infrared Remote-Control Sending chip 4 coordinates with PT2272 infrared remote control receiving chip the transmission realizing signal.Be illustrated in figure 2 described apparatus structure schematic diagram.
Be illustrated in figure 3 installation site schematic diagram during this tester measurement escalator stopping distance.The main frame of tester is arranged on the step plate of escalator, and power wheel directly contacts with step, drives power wheel and rotary coding to take turns uniform movement during escalator operation.Trigger button box is arranged on the scram button 1 of elevator or escalator.
The principle of work of the utility model tester: principle of work as shown in Figure 4, after scram button 1 pressed by escalator, the power-off of staircase power circuit, the interlock Infrared Remote-Control Sending chip 4 of scram button 1 sends ct-off signal this moment, in main frame, infrared remote control receiving chip sends into micro controller system through process after receiving ct-off signal, now rotary encoder starts to count pulse count until elevator stopping, by signaling conversion circuit, corresponding pulse count is sent to micro controller system.Data draw the stopping distance of escalator after micro controller system process, computing, and are transferred to telltale display, and this take off data can also by mini-printer data-printing out.The numerical value specified in elevator surveillance inspection and periodical survey rule can be set to main frame simultaneously, when the stopping distance that this tester is measured exceedes this numerical value, then trigger combined aural and visual alarm and report to the police.
Because the corresponding coder of each pulse rotates a certain angle, the relation of angle and wheel rim girth is utilized just to obtain distance value.Its Computing Principle is as follows: set escalator braking distance as s, the circle wheel radius of rotary coding wheel is r, circle wheel rotates a circle needs n0 pulse (to adopt 10 in the present embodiment for coder, then n0=1024), need n pulse altogether from the power-off of elevator major loop to stop, to be s be for escalator and moving sidewalk braking distance:
In addition this tester can also calculate rear speed, maximum braking acceleration and the average braking acceleration run of escalator braking by obtaining coded data in specified time section (sampling period), obtains the principle of these data as shown in Figure 5.When in escalator operation, tester is in test readiness for action, after elevator scram button 1 is pressed, trigger gang switch, control Infrared Remote-Control Sending chip 4 to transmit, after main frame receives infrared remote control energizing signal, Single-chip Controlling rotary encoder starts counting.Count results sends to micro controller system after conversion, is solidified with the program woven in micro controller system, according to the function of keyboard to set up, can carry out the calculating of corresponding maximum braking acceleration, stopping distance, running velocity, average braking acceleration.
Program curing in above-mentioned micro controller system, software make use of keil uvision2 programmed environment, and program is burnt to micro controller system by serial ports (RS232), and this Software for Design diagram of circuit as shown in Figure 6.After micro controller system initialization, start to detect current value signals, if power circuit power-off detected, impulse singla is sent to micro controller system by coder after treatment, and micro controller system starts to remember pulse count, processes data, calculated braking distance, and result is transferred to telltale, complete test.
Certain above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All modifications done according to the Spirit Essence of the utility model main technical schemes, all should be encompassed in protection domain of the present utility model it.
