Abstract

The invention discloses cab integrated radio communication equipment adopting a listing command mode, wherein a host machine is formed by a control part and a radio station part; the control part of the host machine comprises a main control unit which is formed by a micro processor, the main control unit is connected with the radio station part through a recommended standard (RS)-232 communiation interface, and the main control unit is communicated with an operating display terminal through an RS-422 communiation interface; a master control program signaling mode which is operated in the main control unit adopts the listing command mode; and the main control unit and a man-machine interface (MMI) have agreement on basic software, the MMI does not need to be informed of the number of functional items before an operator needs to use the corresponding function, the main control unit receives a listing inquiry command and then collects all the functional items to generate a list to be fed back to the MMI through the listing command, and multi-packet delivery is supported for the feedback of the listing command. The equipment is suitable for various applications of all the railway bureaus with various line differences; and when additional requirement is generated, the master control program is only needed to be upgraded in a universal series bus flash disk mode for satisfying the requirement, so the equipment is simple to operate and has high efficiency, and the workload of maintenance personnel is reduced.

Description

technical field

[0001] The invention relates to railway wireless dispatching communication equipment, in particular to a locomotive comprehensive wireless communication equipment adopting a list command mode.

[0002] Background technique

[0003] The locomotive integrated wireless communication equipment is referred to as CIR. With the construction of my country's railway GSM-R network, CIR is gradually replacing the 450M general-purpose locomotive radio. The device integrates two working modes of GSM-R and 450M. These two working modes carry voice and data services respectively. For voice services, there are many states due to historical reasons, such as B1, B2, C, and GSM-R. etc., while the function items of the data service include dispatching command transmission, FFSK / GPRS column tail information transmission, train number verification information transmission, self-inspection information transmission, early warning information transmission, etc.

Examples

Embodiment approach

[0016] Such as figure 1 , figure 2 As shown, the operation display terminal (MMI) is only logically connected with the main control unit (see figure 1 Dotted line) for information exchange, and other units of CIR are transparent to the operation display terminal (MMI).

[0017] Firstly, the main control unit and the operation display terminal (MMI) agree on the basic software protocol, which is compatible with the basic communication protocol framework of wireless train dispatching stipulated by the railway transportation base. When the operator needs to use the corresponding function, the MMI unit does not need to know the number of function items. By sending a list query command, the main control unit collects all the function items and generates a list and returns it to the MMI through the list command. When the list command returns, it supports Send multiple packets (up to 255 packets, and the size of a single packet can be adjusted to a maximum of 1024 bytes). Thi...

example 2

[0021] Example 2: Check the startup system service status, select "(61) Query system service startup status" and press the OK button, the operation result is shown as follows: "FTP service is off; TELNET service is off".

example 3

[0022] Example 3: To set GPS navigation parameters, select "(96) GPS navigation parameters" and enter the corresponding parameters and press the OK button. The operation results are as follows: "GPS navigation mode: master control; database loading mode: automatic; positioning accuracy : 15 meters".
