Description
Technical Field
The utility model belongs to the technical field of rail vehicle power supply control, especially, relate to a control two novel circuits of marshalling railcar battery.
Background
In the past, the subway vehicle in the project mostly adopts six marshalling modes, once the marshalling is fixed, parts cannot be disassembled and replaced in the whole life cycle, because the six marshalling vehicles have enough space under the vehicle, two groups of storage batteries are generally arranged, each group of storage batteries is provided with a charger, and the control mode is that the charger charges the storage batteries of the group.
The two-group vehicle grouping mode is more flexible in the grouping mode compared with a six-group vehicle grouping mode, but due to the fact that space under the vehicle is limited, space and weight requirements for installed equipment are met, and higher requirements are placed on functions and control modes of a storage battery system.
Disclosure of Invention
The utility model aims at providing a novel two marshalling vehicle battery control circuit under the prerequisite that does not reduce the system function to reach the purpose that reduces space and weight.
In order to achieve the above object, the utility model provides a two marshalling railcar battery control circuit, its characterized in that: each vehicle of the two grouped vehicles is provided with a charger, one vehicle is provided with a group of storage batteries, a temperature sensor and a voltage sensor are connected between a controller on the first charger and a storage battery, the charger is controlled to charge the storage battery through temperature and voltage, and meanwhile, the controller sends the temperature and voltage parameters to the second charger through a network; the output lines of the two chargers are respectively provided with diodes in the same direction, the storage battery pack supplies power to direct current loads on the vehicles through a bus between the two vehicles, and when a network fails, the two chargers charge the storage battery according to a preset value.
Preferably, the controller on the second charger and the storage battery pack only have one interface connected with the current sensor for collecting monitoring current data.
Preferably, a current sensor is respectively connected between the controller on the first charger and the storage battery pack and on an output line of the first charger.
Preferably, the two groups of storage battery chargers are connected with the storage battery pack through a bus between the two vehicles to charge the storage battery pack.
The utility model discloses a two fill the machine and set up a set of battery, have temperature sensor interface and voltage sensor interface through controller and storage battery, through the temperature, voltage control fills the machine and charges for storage battery, and simultaneously, this controller sends these temperatures, voltage parameter for another platform through the network and fills the machine, makes this platform fill the machine and charge for storage battery according to the same parameter, under the prerequisite of guaranteeing system function, has reduced storage battery's quantity, has reduced the vehicle weight, has reduced occupation space. Meanwhile, control and power supply cables are reduced, the cost is reduced, and the cost performance of the vehicle is improved.
Drawings
Fig. 1 is a logic diagram of the control circuit of the present invention.
Detailed Description
Referring to fig. 1, a charger is respectively arranged on a vehicle a and a vehicle B, a storage battery is arranged on the vehicle B, and the two chargers output in parallel to supply power to a train direct-current load and charge the storage battery. A voltage sensor, a current sensor 1 and a diode are arranged on a circuit at the output end of a charger of the B vehicle, a current sensor 2 is arranged on a circuit for supplying power to a storage battery pack, and voltage information and current information can be transmitted to a controller of the charger through the sensors for output control of the charger. A temperature sensor is arranged in the storage battery pack, and temperature information is sent to a charger controller to be used for output control of the charger. The charger controller of the vehicle B transmits information such as voltage, current, temperature and the like to the charger controller of the vehicle A through a train network, and the charger controller of the vehicle A is also connected with a current sensor 1 and a diode and is controlled according to the same parameters so as to ensure that the same voltage is used for supplying power to a train load and charging a storage battery pack; and under the condition of train network failure, the chargers of the train A and the train B supply power to the train load and charge the storage battery pack according to preset parameters.
