7 is an internal configuration diagram of a battery exchange station according to an embodiment of the present invention.

Referring to FIGS. 6 and 7, the battery exchange station 10 is installed in the form of a platform in which the horizontal frame and the vertical frame constituting the external appearance are substantially 'A' shaped. Here, the vertical frame serves as a supporter for the upper horizontal frame from the floor, and the horizontal frame includes a battery 230 charging device and a moving device for the battery exchange robot 25, and the like.

A plurality of battery charging stations 30 are installed in the interior of the horizontal frame and a plurality of battery charging stations 30 can charge the recovered batteries 230 and a battery 231, Function. At least one battery charging station 30 of the battery charging station 30 maintains a state in which the battery is not mounted to provide a space for storing the recovered battery 230 of thegrounding station 100. [

The battery exchange control unit 20 shown in FIG. 6 includes a battery exchange computer 21, a battery exchange robot controller 22, and a battery charge management controller 23.

The battery exchange computer 21 is connected to the central control unit 400 to transmit information on the number of batteries held in the battery exchange station 10, the charge status of each battery, and the status of the exchange progress, Position and exchange predicted time, and travel schedule information of the streetcars 100 are received. The battery exchange computer 21 recognizes the position information or the arrival time information of the streetcars 100 in operation and confirms the battery state of the streetcars 100 and whether or not the battery is to be replaced and outputs the information to the battery exchange robot controller 22 And transmits a standby mode.

The battery exchange robot controller 22 controls the operation of the battery exchange robot 25 to transfer the cushioning battery 230 located in the battery charging cradle 30 to the battery charging cradle 30 close to the battery exchange position of the floor cradle 100 do. The battery exchange robot controller 22 controls the battery exchange robot 25 to recover the discharged battery 230 of the streetcars 100 and to supply the charged battery 230 231 are mounted on the streetcars 100.

A plurality of battery exchange robots 25 can be inserted into the battery exchange station 10 during the passenger's getting-on / off time so that the batteries installed in the driven vehicle 300 and the driven vehicle 200 can be exchanged at the same time.

The battery 230 recovered from the streetcars 100 may be recharged by being mounted on the charging station 30 of the battery exchange station 10 and mounted on the streetcars 100 after being charged to be reused. The battery charge management controller 23 can predict the battery exchange demand and control the charge rate of the battery 231 being charged in accordance with the running schedule of the streetcars 100. [ For example, in the commuting time zone where the cushioning battery 231 is in high demand, the charging base 30 is set to the rapid charging mode so that the battery can be charged quickly and the operation of the streetcars 100 is interrupted, The battery 231 can be charged by setting the charging stand 30 to the slow charging mode in the afternoon when demand is low. In addition, when the running of the streetcars 100 is completely stopped, the charging of the battery may be suspended and the charging of the battery may be resumed at the midnight power time.

The battery charge management controller 23 can control the charge setting and charging mode of the charging stand 30 to optimize the power use of the battery exchange station 10. [

8 is a configuration diagram of an on-vehicle control unit according to an embodiment of the present invention.

The on-vehicle controller 150 controls electrical components such as a steering wheel, a driving motor, a braking device, a door device, and the like, and a battery and power connection means provided on the road surface.

 The on-vehicle control unit 150 includes an onboard computer 151, a train data transmission device 152, and a battery management system 153.

The onboard computer 151 monitors the operation state of the on-street tram by comparing the stall state of the driver and the stall rate received from the speed sensor with the set rail safe speed. The onboard computer 151 also determines the stop and departure situation at the landing and depot premises in connection with the inverse computer 510. The position can be grasped using a GPS device or wireless communication with the repeater 520, It is determined whether or not it coincides with the operation schedule of the streetcars.

The tram data transmission device 152 wirelessly transmits information such as the position and speed of the tram, the charged state of the tram, the abnormality of the driving and braking device, and the number of passengers to the local control unit 500 or the central control unit 400 do.

The battery management system 153 grasps the charge capacity of the battery mounted on the road surface train, and sets a priority order of battery usage among a plurality of batteries. It also manages the abnormal discharge monitoring of the battery and the power distribution of the vehicle electrical equipment such as an air conditioner.

For example, if the charging power of the battery 230 of the driving vehicle 200 is low and the charging power of the battery 330 of the driven vehicle 300 is high, if the battery exchange station 10 is located at a close distance, The management system 153 may consume the battery 230 of the driving vehicle 200 preferentially and cause the battery exchange station 10 to replace only the battery 230 of the driving vehicle 200. [

If the charging power of the battery 230 of the driving vehicle 200 is low and the charging power of the battery 330 of the driven vehicle 300 is high and the battery exchange station 10 is located remotely, Controls the battery use condition such that the ratio of the charging power of the battery 330 of the driven vehicle 300 to that of the driven vehicle 300 is matched by preferentially consuming the battery 330 of the driven vehicle 300. [ Thereafter, the battery exchange station 10 may exchange both the driving vehicle 200 and the batteries 230 and 330 of the driven vehicle 300.

If the charging state of the batteries 230 and 330 of the driven vehicle 200 and the driven vehicle 300 is low and it is difficult for the battery exchange station 10 to operate normally, it is possible to prevent a situation where the movement of the streetcars on the rails is interrupted , It is possible to switch to the emergency operation mode in which electric power is supplied only to the device related to the movement of the streetcars 100. [ In the emergency operation mode, it is possible to selectively reduce or shut off the electric power supply to the auxiliary electric equipment such as the lighting of the streetcars 100 or the air conditioner. The traveling distance of the road surface tram can be increased through the emergency operation mode and the road surface can be moved to the battery exchange station 10.

In the example of the present invention, each function is described as being processed by a separate apparatus or computer, but it is technically obvious that each computer and apparatus may be constituted by one system apparatus or connected by a network.
