The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Electric locomotive of the present invention comprises controller, the pressure switch being connected with controller by first interface and the brake cylinder being connected with pressure switch;
Wherein, first interface be in electric locomotive for the I/O mouth of Bonding pressure switch and controller, controller can be connected with first interface by bus.
Fig. 1 shows the diagram of circuit of the brake control method of the disclosed a kind of electric locomotive of the embodiment of the present invention, and as shown in Figure 1, the method can comprise:
Step 101: obtain the level of first interface, and determine the type of described level;
When electric locomotive is switched to after standby braking mode by normal brake application pattern, electric locomotive is in air brake state, operating personal can be controlled by controlling air brake handle the pressure of equalizing reservoir, and equalizing reservoir is connected with brake cylinder, the pressure of brake cylinder and the pressure of equalizing reservoir equate; That is to say, operating personal can be controlled indirectly by air brake handle the pressure of brake cylinder, thereby applies air-making power for electric locomotive;
Pressure switch can detect the pressure of the brake cylinder of the electric locomotive under air brake state, and compare with the first preset pressure, when the pressure of the brake cylinder of the electric locomotive under air brake state is less than the first preset pressure, pressure switch generates the first level, when the pressure of the brake cylinder of the electric locomotive under air brake state is more than or equal to the first preset pressure, pressure switch generates second electrical level.
It should be noted that, the type of the first level and second electrical level does not have concrete restriction, and when the first level is high level, second electrical level is low level; When the first level is low level, second electrical level is high level.
Wherein, the first preset pressure is the standard that whether can open electric braking, when the pressure of brake cylinder is less than the first preset pressure, can open electric braking, and electric locomotive can not have an accident; And when the pressure of brake cylinder is more than or equal to the first preset pressure, forbid opening electric braking, if open by force electric braking, electric locomotive may have an accident.
It should be noted that, the first preset pressure can be set according to operator's practical experience, at this, does not limit its occurrence, and for example, the first preset pressure can be 90KPa.
Step 102: when described level is the first level, open electric braking, apply electric braking force to allow for electric locomotive;
Step 103: when described level is second electrical level, close electric braking, to forbid that electric locomotive is applied to electric braking force.
When level is the first level, illustrate that the pressure of brake cylinder is less than the first preset pressure, open electric braking, now, electric locomotive can adopt air brake and electric braking simultaneously;
When level is second electrical level, illustrate that the firm pressure of braking is more than or equal to the first preset pressure, close electric braking, now, electric locomotive only can adopt air brake.
It should be noted that, after opening electric braking, operating personal can be that electric locomotive applies electric braking force by controlling electric braking handle; And after closing electric braking, electric braking handle will be fixed, operating personal can not be that electric locomotive applies electric braking force by controlling electric braking handle.
In embodiments of the present invention, when electric locomotive is switched to after standby braking mode by normal brake application pattern, can, guaranteeing, on the trouble-proof basis of electric locomotive, to be used in conjunction with air brake and electric braking, reach the object of saving the energy.
For the ease of understanding, with an application example, describe, pressure switch detects the pressure of the brake cylinder of the electric locomotive under air brake state, when the pressure of brake cylinder is more than or equal to 90KPa, pressure switch is closed, and first interface is high level, and controller cuts out electric braking; When the pressure of brake cylinder is less than 90KPa, pressure switch is opened, and first interface is low level, and controller is opened electric braking.
When electric locomotive is switched to after standby braking mode by normal brake application pattern, controller is determined when level is the first level, open electric braking, now, electric locomotive can use air brake and electric braking simultaneously, that is to say, operating personal not only can apply electric braking force to electric locomotive by controlling electric braking handle, can also to electric locomotive, apply air-making power by controlling air brake handle, so, when the pressure of brake cylinder surpasses the first preset pressure, also may cause electric locomotive et out of order.
Therefore, in order further to improve the safety of electric locomotive, the present invention also provides a kind of brake control method of electric locomotive, and as shown in Figure 2, the method can comprise:
