Native system can be controlled four stepper motor work simultaneously, thereby respectively four groups of 12 bicycles is filled wind, alleviates.Quicken to alleviate, sew, sensitivity, stabilize, partly alleviate automatic ventilation test.
The operation of native system experimentation is carried out according to instruction code.Instruction code is seen attached list.
With 1 group of 1 position is example:
Before beginning test, testing crew is opened native system power supply and host power supply, can begin test.
1, testing crew is pressed " 1.0.0.# " and the DIAL key on the intercom, voice system feedback " the I group resets, and can start working ".
2, press " 1.1.1.# " key and DIAL key, voice system feedback " 1 group begins to fill wind ", behind the wait certain hour, pressure reaches 500KPa and promptly feeds back " 1 group is filled wind and finishes ".
3, press " 1.1.2.# " and DIAL key, voice suggestion " 1 group begins leak-test " pressurize 1 minute, Brake pipe pressure descends and is no more than 10KPa, voice answering " 1 group of leak-test is qualified ", if descending, Brake pipe pressure surpasses 10KPa, then voice answering " 1 group of leak-test is defective " needs check system to sew situation.
4, during sensitivity test, press " 1.1.3.# " and DIAL key, voice suggestion " 1 group begins sensitivity test ", decompression 40KPa, braking action must take place in the various brake of bicycle before brake pipe reduces pressure 40KPa; Pressurize voice suggestion after 1 minute " 1 fen clock time of 1 group of sensitivity test arrives ".And in one minute natural remission must not take place.
5, press " 1.1.4# " and DIAL key, then voice suggestion " 1 group begins to alleviate test ", various valve all should be alleviated in 45 seconds and finish.
6, press " 1.1.5.# " and DIAL key, brake hard must not take place, and confirm that piston travel is up to specification in then voice suggestion " 1 group begins stable test " decompression 140KPa.
7, press " 1.1.6.# " and DIAL key, voice suggestion " 1 group begins emergency braking tests ", the brake pipe 140KPa (100KPa) that reduces pressure is preceding, and brake must play the brake hard effect.After waiting for about 30 seconds, microcomputer is answered " 1 group of emergency braking tests finishes ".
8, press " 1.1.7.# " and DIAL key, voice suggestion " 1 group begins to quicken to alleviate the threshold test ".Computer controlled automatic revolving valve handgrip is put one, and brake pipe fills wind to level pressure, and the revolving valve handgrip is put four decompression 100KPa, moves to three pressurizes then, treat pressure stability after the revolving valve handgrip put two, checking cylinder begins to alleviate.
9, press " 1.1.8.# " and DIAL key, behind voice suggestion " 1 group begins semi-automatic graduated release valve test " the pressure decompression 50KPa, voice suggestion " 1 group of decompression 50KPa ", testing crew should draw the graduated release valve handgrip to unclamp after second to standard-sized sheet position 3-5, cylinder pressure air to be braked has been arranged (after about 20 seconds) microcomputer control step driven by motor revolving valve handgrip to five more automatically, reduce pressure and return three pressurizes behind the 50KPa, waits for after 30 seconds, computing machine gives voice suggestion " 1 group of semi-automatic graduated release valve is tested and finished ".
10, after Total Test finished, by " 1.0.9.# " and DIAL key, then voice suggestion " battery of tests ends " was also deposited content of the test and result.
Heavy, backward mode of operation that the present invention has replaced makes high-tech become advanced yield-power.A goods repair shop (12) is only just passable with this cover system, has saved working time and table of equipment number and maintenance facility expense.This system applies in system-wide, can guarantee safety in production and produce tremendous economic and social benefit.
