A kind of elevator is closed the door kinetic energy dynamic testing method, and it passes through pressure and speed in dynamic test door closing procedure, obtains, by computing, kinetic energy of closing the door.By distinguishing and calculating to the speed in door closing procedure, pressure, displacement and time relationship, obtain the door kinetic energy test value in elevator door closing procedure.
Description
Technical field
The present invention relates to elevator detection method is and in particular to a kind of kinetic energy dynamic test system of closing the door being applied to elevator horizontally sliding door.
Background technology
Measure under average door closing speed or not should be greater than 10J when calculating in the kinetic energy of closing the door of regulation in 8.7.2.1.2 in GB7588.
In GB7588,8.7.2.1.1.3 specifies door leaf in the case of protection device inefficacy,[0002]The kinetic energy of defined can not be more than 4J.
GB7588 specify to power-actuated non-automatic door, under user of service's continuous control and monitoring, by lasting pressing button or the like（Ongoing operation runs and controls）When closing door, when pressing[0002]When the kinetic energy calculating or measuring is more than 10J, average closing door speed the fastest not should be greater than 0.3m/s（8.7.2.1.2）.
Existing domestic standard and regulation elevator slide door is not closed the door kinetic energy dynamic survey method of testing detailed rules and regulations regulation.
External TUV and Dalian Dalian Jin Shi development in science and technology company limited have one kind to close the door kinetic-energy testing instrument DTML-JC, it be using spring-compressed during energy conversion principle, the kinetic energy of door is converted to the decrement of spring, the kinetic energy closed the door is tested by the decrement calculating spring.Computing formula is E=1/2kx2But, according to standard, this kinetic energy is measurement or value of calculation under average door closing speed, and must be in whole track of closing the door using this test instrunment, and pointwise measures, so many points of N theoretically should be had on track of entirely closing the door, not only test job amount is huge, and precision it cannot be guaranteed that.
The another drawback of DTML-JC is whether the kinetic energy that can not describe under average speed is more than 10J.
DTML-JC can not test the corresponding door closing speed when kinetic energy is more than 10J, therefore can not differentiate whether the kinetic energy of this point meets the requirements.
Content of the invention
The purpose of the present invention overcomes the deficiencies in the prior art, provide a kind of be suitable for a kind of dynamic test, be can to test any point entirely closed the door in stroke to close the door the method for kinetic energy.
In order to solve the problems of background technology, the present invention is to employ the following technical solutions：It comprises including signal processor, and signal processing system includes to force signal and speed（Or displacement）The collection of signal and process, force signal is accepted and is passed to force transducer by the Force receiver with door directly contact；Speed（Or displacement）Signal is moved by Force receiver and is passed to velocity sensor（Or displacement transducer）Obtain, signal processor is to force signal, speed（Or displacement）Signal moved after being processed in elevator door instantaneous kinetic energy, the motion of Force receiver relies on the guiding mechanism restriction being connected with Force receiver, and guidance system is fixed on doorframe.
By Force system by stress thin slice, force transducer, base and connection（Or conducting system）Composition, main member is that the thin slice between pluggable door undertakes, and force sensor directly can be connected with thin slice or is connected with thin slice by movement conduction mechanism, and thin slice is connected with sliding bottom, and base is connected with by draught control mechanism.
Base and the connected mode by draught control mechanism, can be to be directly connected to, or be connected by intermediate transfer chain；Intermediate transfer chain can be gear, rack-and-pinion, turbine and worm, and belt connects.
Test starts, and door closing force is by force mechanism of closing the door（Close the door PTO）Power is transported to force transducer, speed（Or displacement）Export speed（Or displacement）Sensor, then by force transducer, speed（Displacement）The signal output of sensor, to sampled-data system, carries out data processing, preserves display.

By figure line sliding, speed v=dl/dt, instantaneous kinetic energy and mean kinetic energy E of corresponding point can be inquired about, see signal Fig. 3.
The present invention is compared with prior art compared with advantage.
Once test completes close the door kinetic energy and the velocity amplitude of every bit and the collection analysises of force data amount to every bit in stroke of entirely closing the door, the data measured more meets reality, not only automatically obtain the instantaneous value of kinetic energy, maximum, minima in whole door closing procedure, it is obtained in that average speed by calculating, thus calculate the kinetic energy of closing the door under average speed, and data has preservation reproduction function, can look into the kinetic energy of closing the door taking any point in stroke of closing the door；Data testing accuracy is higher.
Compared with spring balance method of testing, test data is stable, will not be different because of tester, and big difference in test result.
This instrument employs indirectly testing method of testing, substantially reduces apparatus structure size and weight.
