Abstract
The invention relates to a power-loss time-delay relay-type alert control method. The power-loss time-delay relay-type alert control method comprises the following steps: carrying out circuit layout; continuously pressing an alert button so as to enable an emergency braking device to keep in a non-trigger state; releasing the alert button to begin power-loss delay, so that an intermediate relay is out of power so as to enable the emergency braking device to be in a triggering state; emergently braking a train. According to the power-loss time-delay relay-type alert control method, the high frequency power loss and power receiving of the intermediate relay in a short period of time can be prevented so as to guarantee the service life of a whole alert circuit, and the emergency braking can be started in time after the alert button is released at a scheduled time, so that the reliability is high.
Description
Technical field
The present invention relates to the vigilant control method of a kind of dead electricity slug relay's type, be applicable to guideway vehicle.
Background technology
According to the knowledge of the applicant, vigilant loop is all housed on guideway vehicle, can prevent driver in operational process, doze off, careless or meet accident, and remind driver to want normal driving, conventionally driver one leave driver controller after 3 seconds by emergency braking.In existing vigilant loop, conventionally adopt the DMRR relay of connecting with acknowledgment button, can be after acknowledgment button unclamps 3 seconds will dead electricity, then trigger emergency braking.But DMRR relay adopts electronic type time delay, its life-span is shorter, in addition driver occurs that in driving procedure hand trembles phenomenon unavoidably, so just cause relay at short notice dead electricity, electric, high-frequency action like this, to aggravate to shorten its life-span, and easily cause fault rate to increase.
Summary of the invention
Technical matters to be solved by this invention is: overcome the problem that prior art exists, provide a kind of dead electricity slug relay's type vigilant control method, adopt intermediate relay, ensure the service life in vigilant loop, reliability is high.
The technical scheme that the present invention solves its technical matters is as follows:
Dead electricity slug relay type is watched out for control method, comprises the following steps:
The first step, will go between is electrically connected with train positive bus-bar; At leading-out terminal connect successively acknowledgment button and the resistance 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; Determine equivalent resistance and the equivalent inductance of resistance, capacitance and intermediate relay according to voltage between positive and negative busbar and default delay time;
Second step, in the time of 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 not triggering state; Meanwhile, electric capacity is in charge condition;
The 3rd step, in the time that acknowledgment button is released, acknowledgment button automatically resets and being connected of disconnection and train positive bus-bar; Electric capacity starts electric discharge lasting delay time, makes the coil of intermediate relay in delay time, keep obtaining the normal open switch of electricity condition adhesive intermediate relay, and outside emergency braking apparatus continues maintenance and do not trigger state in delay time;
The 4th step, in the time that delay time finishes, the coil losing electricity of intermediate relay, makes the normal open switch of intermediate relay return back to normally open, now outside emergency braking apparatus enters triggering state, makes train emergency braking.
The present invention further perfect technical scheme 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 it is 15V that minimum work keeps voltage; Delay time is 3 seconds.
The present invention can avoid intermediate relay at short notice high-frequency dead electricity, electric, ensure service life in whole vigilant loop, can guarantee again can start in time emergency braking 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.
The specific embodiment
With reference to the accompanying drawings and in conjunction with the embodiments the present invention is described in further detail.But the invention is not restricted to given example.
Embodiment
First, connect up by Fig. 1: will go between and be electrically connected with train positive bus-bar; At leading-out terminal connect successively acknowledgment button DMS and the resistance DMZ 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, determine equivalent resistance and the equivalent inductance of resistance DMZ resistance, electric capacity DMC capacity and intermediate relay DMR according to voltage between positive and negative busbar and default delay time: 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 it is 15V that minimum work keeps voltage.
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 respectively a switch.The end of incoming cables A1 via line T2 of intermediate relay DMR coil is electrically connected with the lead-in wire T1 that is 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 that is connected to negative busbar.Intermediate relay DMR normal open switch comprises contact 13-14,23-24,31-32,41-42.
Then, in the time of 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 not triggering state; Meanwhile, electric capacity DMC is in charge condition.
In the time that acknowledgment button DMS is released, acknowledgment button DMS automatically resets and being connected of disconnection and train positive bus-bar; Electric capacity DMC starts electric discharge lasting delay time, makes the coil of intermediate relay DMR in delay time, keep obtaining the normal open switch of electricity condition adhesive intermediate relay DMR, and outside emergency braking apparatus continues maintenance and do not trigger state in delay time.In the present embodiment, delay time is 3 seconds.
In the time that delay time finishes, the coil losing electricity of intermediate relay DMR, makes the normal open switch of intermediate relay DMR return back to normally open, and now outside emergency braking apparatus enters triggering 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 requirement of the present invention.
