Often downloading data is to carry out in garage, just can only lean on train storage battery power supply in storehouse without high pressure, and the time of support is relatively
Short, it is possible to cannot to have downloaded.
2, preserved by the onboard memory chip within electronic brake control unit
It is generally of FLASH or ferroelectric memory chip inside the electronic control unit of brakes, stores for data.
The subject matter of this mode is as follows:
(1) storage chip capacity is the least, general only 1M～8M byte, is only used for recording before and after fault or particular event one
The data of section time, it is impossible to Coutinuous store service data, due to finite capacity, the time interval of data storage can not be the least.
(2) download data to need to pass through serial communication interface, it is also desirable to train powers on, the problem having aforesaid operations inconvenience equally.
3, part municipal rail train is stored by braking maintenance terminal
The brakes of part municipal rail train has the CAN running through full row, is provided with maintenance terminal at drivers' cab, safeguards eventually
The data that end obtains full train braking system by CAN store.The subject matter of this mode is as follows:
(1) it is only limitted to the municipal rail train with full row CAN, is not suitable for there is no the municipal rail train of CAN, machine
The rail vehicle such as car, EMUs.
(2) due to the restriction of full row CAN baud rate, the data of full train braking system are all carried out by CAN
Transmission, the transmission cycle necessarily causing packet is relatively big, and the time interval that data store is relatively big, and electronic brake control unit
Some internal status datas are not delivered in bus, it is impossible to store.
