The microcomputer network control technology of Locomotive Brake System, because it has response, command speed is fast, Stress control is smart
Degree is high, control piper quantity is few and can realize the advantages such as network data slitless connection with locomotive microcomputer, has obtained extensively
Application.But, the fault in terms of the microcomputer network control device once generating electronic equipment of brakes or network communication, will
Make locomotive produce punishment braking, i.e. locomotive braking system can automatically control Train Stopping, before brake fault does not eliminate, locomotive
Can not run.This situation can only wait that other locomotives come to the rescue, and causes working line to block.
Summary of the invention
The purpose of the present invention overcomes the deficiency of above-mentioned prior art exactly, it is provided that a kind of standby control of Locomotive Brake System
Device processed.
The object of the present invention is achieved like this: a kind of Locomotive Brake System standby control device, it is characterised in that
By cutting out cock, alternate brake valve, equalizing reservoir, relay valve, air relief valve, Pressure gauge form, wherein:
Cut out cock, equipped with the microswitch that can send signal to the microcomputer of locomotive control, it is achieved brakes exists
The conventional conversion controlled between device and standby control device；
Alternate brake valve, three working positions of its joystick control the pressure of equalizing reservoir and change: retarder location, equalize wind
Cylinder is arranged to air by service braking decompression rate；Alleviating position, locomotive blast main fills wind to equalizing reservoir；Pressurize position, cuts off equilibrium

Technical scheme, occurs electronic equipment or network at locomotive braking system because of its microcomputer network control device
Communication aspect fault and he causes punishment braking time, by simple handover operation, its microcomputer network control device can be shielded
Fall, recover the properly functioning of locomotive.
Accompanying drawing explanation
Fig. 1 is the Locomotive Brake System standby control principle of device schematic block diagram of the embodiment of the present invention.
Detailed description of the invention
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
The a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under not making creative work premise, broadly falls into the scope of protection of the invention.
Referring to accompanying drawing, the Locomotive Brake System standby control device of the present embodiment by cutting out cock, alternate brake valve,
Equalizing reservoir, relay valve, air relief valve, Pressure gauge form.
Cut out cock for realizing brakes conversion between conventional control device and standby control device, control standby
With controlling whether device puts into.Equipped with microswitch on cutting out cock, locomotive microcomputer utilizes this signal to produce interrelated logic control.
When emergency brake system needs to put into, microswitch signal entrance locomotive microcomputer:
1. cut off microcomputer and control the power supply of brakes；
2. release locomotive traction block；
3. put at locomotive microcomputer display screen display alternate brake, and record on-position.
The pressure that alternate brake valve controls equalizing reservoir with three working positions of its joystick changes:
1. retarder location, equalizing reservoir connection air, equalizing reservoir pressure, is braked to air by service braking decompression rate row
Valve handle controls the decompression amount of equalizing reservoir in the time of retarder location.
2. alleviating position, equalizing reservoir connection blast main, blast main fills wind to 600kPa to equalizing reservoir.
3. pressurize position, cuts off equalizing reservoir and blast main, the path of air, and equalizing reservoir pressure keeps constant.
Equalizing reservoir controls pressure signal according to the working position of alternate brake valve joystick to relay valve transmission.
Relay valve be used for according to equalizing reservoir pressure produce a certain proportion of Brake pipe pressure, such as 1 to 1, i.e. play stream
The effect of amount amplifier.
Blast main is passed the pressure of equalizing reservoir by air relief valve, limits the maximum pressure of equalizing reservoir.Such as blast main
Pressure is 900kPa, and after air relief valve reduces pressure, equalizing reservoir maximum pressure is 600kPa.
Pressure gauge: display equalizing reservoir force value.
It is as follows that the alternate brake of the present embodiment controls logic.
Alternate brake valve controls the force value change of equalizing reservoir；Relay valve, according to the decompression amount of equalizing reservoir, produces phase
Deng brake pipe pressure reduction；Brake pipe pressure reduction enters distributing valve module, and distributing valve module response brake pipe decompression amount produces 2.5
Effect pipe pressure (i.e. effect pipe pressure is 2.5 times of brake pipe pressure reduction) than 1；Effect pipe pressure enters checking cylinder relaying mould
Block, checking cylinder trunk module response effect pipe pressure produces the brake-cylinder pressure of 1 to 1, and brake-cylinder pressure enters brake cylinder and makes train
Produce braking action.
Last it is noted that above example is only in order to illustrate technical scheme, it is not intended to limit；Although
With reference to previous embodiment, the present invention is described in detail, it will be understood by those within the art that: it still may be used
So that the technical scheme described in foregoing embodiments to be modified, or wherein portion of techniques feature is carried out equivalent；
And these amendment or replace, do not make appropriate technical solution essence depart from various embodiments of the present invention technical scheme spirit and
Scope.
