Abstract
Control method watched out for by the dead electricity slug relay type that the present invention relates to, comprise: arrange circuit, continuing to press acknowledgment button makes emergency braking apparatus keep non-trigger state, unclamp acknowledgment button and start dead electricity time delay, intermediate relay dead electricity makes emergency braking apparatus enter trigger state, train emergency braking.The present invention can avoid intermediate relay at short notice high-frequency dead electricity, electric, ensure the service life in whole vigilant loop, can guarantee again can start emergency braking in time after acknowledgment button unclamps the schedule time, reliability is high.
Description
Technical field
The present invention relates to a kind of dead electricity slug relay type and watch out for control method, be applicable to guideway vehicle.
Background technology
According to the knowledge of the applicant, guideway vehicle is all equipped with vigilant loop, can prevents driver from dozing off in operational process, careless or meet accident, and remind driver to want normal driving, usual driver one leaves driver controller after 3 seconds by emergency braking.Usually the DMRR relay of connecting with acknowledgment button is adopted in existing vigilant loop, can will dead electricity after acknowledgment button unclamps 3 seconds, then trigger emergency braking.But DMRR relay adopts electronic type time delay, and its life-span is shorter, in addition there is hand shaking phenomenon unavoidably in driver in driving procedure, so just cause relay at short notice dead electricity, electric, high-frequency action like this, its life-span is shortened in aggravation, and easy causing trouble rate increases.
Summary of the invention
Technical matters to be solved by this invention is: overcome prior art Problems existing, provides a kind of dead electricity slug relay type to watch out for control method, adopts intermediate relay, and ensure the service life in vigilant loop, reliability is high.
The technical scheme that the present invention solves its technical matters is as follows:
Control method watched out for by dead electricity slug relay type, comprises the following steps:
The first step, will go between is electrically connected with train positive bus-bar; To connect successively acknowledgment button and resistance at the leading-out terminal of lead-in wire, the coil of parallel capacitance, backward diode and intermediate relay respectively between resistance leading-out terminal and train negative busbar; The normal open switch of intermediate relay is connected with outside emergency braking apparatus; Acknowledgment button is runback bit-type normal open switch; According to equivalent resistance and the equivalent inductance of voltage between positive and negative busbar and default delay time determination resistance, capacitance and intermediate relay;
Second step, when train operation, continue to press acknowledgment button, make the coil of intermediate relay obtain the normal open switch of electric adhesive intermediate relay, outside emergency braking apparatus keeps non-trigger state; Meanwhile, electric capacity is in charge condition;
3rd step, when acknowledgment button is released, acknowledgment button automatically resets and disconnects and the connection of train positive bus-bar; Electric capacity starts to discharge and continues delay time, the coil of intermediate relay is kept in delay time electricity condition the normal open switch of adhesive intermediate relay, outside emergency braking apparatus continues to keep non-trigger state in delay time;
4th step, at the end of delay time, the coil losing electricity of intermediate relay, make the normal open switch of intermediate relay return back to normally open, now outside emergency braking apparatus enters trigger state, makes train emergency braking.
The perfect further technical scheme of the present invention is as follows:
Preferably, between positive and negative busbar, voltage is DC110V; Resistance is 470 ohm; Capacitance is 220 μ F; The equivalent resistance of intermediate relay is 5000 ohm, and equivalent inductance is 55H, and minimum work keeps voltage to be 15V; Delay time is 3 seconds.
The present invention can avoid intermediate relay at short notice high-frequency dead electricity, electric, ensure the service life in whole vigilant loop, can guarantee again can start emergency braking in time after acknowledgment button unclamps the schedule time, reliability is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
With reference to the accompanying drawings and the present invention is described in further detail in conjunction with the embodiments.But the invention is not restricted to given example.
Embodiment
First, connect up by Fig. 1: will go between is electrically connected with train positive bus-bar; To connect successively acknowledgment button DMS and resistance DMZ at the leading-out terminal of lead-in wire, the coil of parallel capacitance DMC, backward diode D1601 and intermediate relay DMR respectively between resistance DMZ leading-out terminal and train negative busbar; The normal open switch of intermediate relay DMR is connected (not shown) with outside emergency braking apparatus; Acknowledgment button DMS is runback bit-type normal open switch.
Meanwhile, according to equivalent resistance and the equivalent inductance of voltage between positive and negative busbar and default delay time determination resistance DMZ resistance, electric capacity DMC capacity and intermediate relay DMR: in the present embodiment, between positive and negative busbar, voltage is DC110V; Resistance DMZ resistance is 470 ohm; Electric capacity DMC capacity is 220 μ F; The equivalent resistance of intermediate relay DMR is 5000 ohm, and equivalent inductance is 55H, and minimum work keeps voltage to be 15V.
In addition, as shown in Figure 1, the leading-out terminal of resistance DMZ, the end of incoming cables of electric capacity DMC, diode D1601, intermediate relay DMR is also in series with a switch respectively.The end of incoming cables A1 via line T2 of intermediate relay DMR coil is electrically connected with the lead-in wire T1 being connected to resistance DMZ leading-out terminal, and the leading-out terminal A2 via line T3 of intermediate relay DMR coil is electrically connected with the lead-in wire T4 being connected to negative busbar.Intermediate relay DMR normal open switch comprises contact 13-14,23-24,31-32,41-42.
Then, when train operation, continue to press acknowledgment button DMS, make the coil of intermediate relay DMR obtain the normal open switch of electric adhesive intermediate relay DMR, outside emergency braking apparatus keeps non-trigger state; Meanwhile, electric capacity DMC is in charge condition.
When acknowledgment button DMS is released, acknowledgment button DMS automatically resets and disconnects the connection with train positive bus-bar; Electric capacity DMC starts to discharge and continues delay time, the coil of intermediate relay DMR is kept in delay time electricity condition the normal open switch of adhesive intermediate relay DMR, outside emergency braking apparatus continues to keep non-trigger state in delay time.In the present embodiment, delay time is 3 seconds.
At the end of delay time, the coil losing electricity of intermediate relay DMR, make the normal open switch of intermediate relay DMR return back to normally open, now outside emergency braking apparatus enters trigger state, makes train emergency braking.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of application claims.
