Embodiment 1

[0024] Embodiment 1: as figure 1 As shown, when the old-fashioned engine is connected to the working mode, the acquisition module 8 is connected with the throttle position sensor 5, the direction handle 6 and the reserved input signal 7, and the interface controller 3 does not need to communicate with the engine control system 11 through CAN communication. The degree signal is directly provided by the throttle position sensor 5, which is a voltage analog quantity of 0-5V, and is collected by the ADC module in the MC9S08DZ60 chip. The direction signals that reflect the driver's operation intention include three signals: forward, empty, and backward, which are provided by the direction handle 6 and are 0-24V switching values, which are collected by the acquisition module 8 . The switch input in the acquisition module 8 is BTS723GW, and this chip can be flexibly configured as a switch input of 0-5V, 0-12V, and 0-24V. 7 is the reserved relevant input signal, among which 10 channe...

Embodiment 2

[0025] Embodiment 2: as figure 1 As shown, when the electronic engine is connected to the working mode, the acquisition module 8 does not need to be connected to the throttle position sensor 5, and the throttle opening signal is exchanged by the engine control system 11 with the CAN communication module 4 in the form of CAN messages. The direction signals that reflect the driver's operation intention include three signals: forward, empty, and backward, which are provided by the direction handle 6 and are 0-24V switching values, which are collected by the acquisition module 8 . The switch input in the acquisition module 8 is BTS723GW, and this chip can be flexibly configured as a switch input of 0-5V, 0-12V, and 0-24V. 7 is the reserved relevant input signal, among which 10 channels are reserved for digital input, and 5 channels are reserved for voltage analog input. After the above input signals are processed by the controller processing module 9, the starting accelerator ope...

Abstract

The invention discloses an engine and transmission accelerator linkage connector controller for a track car. The connector controller is arranged between an engine control system and a transmission control system and comprises a CAN communication module, a controller processing module and a CAN communication module, wherein the CAN communication module, the controller processing module and the CAN communication module are connected in series in sequence, and the CAN communication modules and the controller processing module are respectively provided with an external connector. The controller processing module is further connected with a collecting module, and the collecting module is connected with working pattern selecting buttons and is provided with an external connector. The controller is high in generality, capable of being adapt to engines of different types, flexible in configuration and capable of effectively connecting the transmission control system, the engine control system and other control systems of the car into a whole organically.

Description

technical field [0001] The invention relates to the technical field of interface controllers for railway vehicles, in particular to a throttle linkage interface controller for engines and transmissions used in railway vehicles. Background technique [0002] In the power transmission system of rail cars, the throttle linkage control of the engine and transmission is a very important technology to ensure the high efficiency of the transmission system, which will directly affect the matching performance of the engine and transmission, thus affecting the transmission performance of the whole vehicle . At present, there are two types of old-fashioned engines and electronic engines on the market. The former must collect the engine throttle opening signal from the throttle position sensor; the latter can directly obtain the engine throttle opening signal from the engine control system through CAN messages; at the same time, the railway car transmission In order to ensure the safet...
