Embodiment 1

[0029] see figure 1 , this embodiment discloses a master-slave monitoring circuit suitable for subway engineering vehicles, which may include: a first relay, a second relay, a third relay, a time relay, a master-slave selection switch group, a first reconnection electrical connection and Second reconnection cable.

[0030] The positive pole of the control power supply (the positive bus bar of the control power supply) is connected to the negative pole of the control power supply (the negative bus bar of the control power supply) through the first normally open contact H11 of the first relay connected in series, the diode, and the time relay coil J. The positive pole of the control power supply is connected to the negative pole of the control power supply through the master-slave selection switch group connected in series and the second relay coil J2. The second normally open contact H12 of the first relay and the normally closed contact D of the time relay are connected in pa...

Embodiment 2

[0041] see image 3 , this embodiment discloses another master-slave monitoring circuit suitable for subway construction vehicles. It further includes: a fourth relay, one end of the coil of the fourth relay is connected to the first reconnection cable, and the other end is connected to the negative pole of the control power supply.

[0042] When the first reconnection cable is powered on, the coil J4 of the fourth relay is powered on. By monitoring the fourth relay, it can be monitored whether an engineering vehicle has selected the main operating terminal. Furthermore, the master-slave selection conflict fault caused by reselecting the master operation terminal can be avoided. The fourth relay can also use a relay whose model is HH53P11.

[0043] The design applicable to the subway construction vehicle disclosed by the application has the following advantages:

[0044] Realize the monitoring of the master-slave selection state of multiple construction vehicles marshalling...

Abstract

The invention discloses a primary-secondary monitoring circuit applied to metro engineering vehicles. The positive pole of a control power supply is connected with the negative pole through a first relay normally-opened contact, a diode and a time replay. The positive pole of the control power supply is connected with the negative pole through a primary and secondary selective switch assembly and a secondary replay coil, the first relay normally-opened contact is in parallel connection with the normally-closed contact of the time relay, and the other end of the primary and secondary selective switch assembly is connected with a first relay coil. A first reconnection cable is connected with the diode of each engineering vehicle, after a second replay normally-opened contact is in series connection with a first relay normally-closed contact, one end is connected with the first reconnection cable, and the other end is connection with a second reconnection cable. One end of a third relay coil is connected with the second reconnection cable, and the other end of the third relay coil is connected with the negative pole of the control power supply. The diode is combined with a relay, the state that whether the second reconnection cable is connected with the power supply is monitored, and whether the fault situation that a plurality of operation ends are selected to be the main operation ends exits is determined.

Description

technical field [0001] The application relates to the technical field of urban rail transit, and more specifically, relates to a master-slave monitoring circuit suitable for subway construction vehicles. Background technique [0002] Master-slave selection is a necessary operation for all rail vehicles during operation. In order to ensure the safe running of the rail transit vehicle, the driver's operation of the vehicle can only be performed when an operating terminal is selected as the main operating terminal. When two or more operating ends are selected as the main operating ends, the rail vehicle should immediately take protective action. [0003] At present, due to the different characteristics of electric locomotives and urban rail vehicles, the methods of monitoring master-slave have their own characteristics: [0004] When multiple electric locomotives are reconnected and running, the driver's key electrical signal is generally fed back to the network control syste...
