Main frame is connected with GSM-R data processing module TCU by RS422 type serial ports;
The train that controlled train tail apparatus is installed has to operate on the rail transportation circuit of GSM-R digital mobile communication network covering, and main frame and driver's control box connect by the data wireless transmission equipment of being made up of Ground Application node, GSM-R network, OCU, TCU.
The invention has the beneficial effects as follows:
1. the present invention proposes the notion of controlled decompression air draft, realizes the wireless transmission of the synchronous decompression air draft information between train locomotive driver's control box and the controlled train tail apparatus main frame, carries out the decompression brake operating by the controlled train tail apparatus main frame.Thereby the controllability that has realized last vehicle of train braking system decompression amount has realized the braking of reducing pressure synchronously of last vehicle of train and train locomotive, reaches to accelerate whole train braking speed, reduce the train longitudinal impulse, shorten the train braking distance, improve the purpose of whole train braking effect.
2. the present invention introduces railway digital mobile communication technology GSM-R technology, has realized that the data wireless transmission equipment of being made up of Ground Application node, GSM-R network, vehicle-carrying communication unit OCU, GSM-R data processing module TCU realizes the wireless transmission of the synchronous air draft information that reduces pressure between the main frame of train locomotive driver's control box and controlled train tail apparatus.
Description of drawings
Fig. 1 is that controlled train tail apparatus is formed structure chart.
Among the figure: driver's control box 1, data wireless transmission equipment 2, main frame 3.
Embodiment
The invention will be further described below in conjunction with accompanying drawing:
A kind of controlled train tail apparatus comprises: driver's control box 1, data wireless transmission equipment 2 and main frame 3.
