At present, freight locomotive crews have to perform long slope traction tasks, which require long operation time, many safety risks, and many traction and braking regulations. They must prevent the locomotive from stopping on the uphill slope and losing control on the downhill slope. Therefore, the crew's operating skills are particularly high.

[0003] At present, locomotive crew members mainly judge whether the locomotive can brake and whether it can be relieved through experience, the position of the locomotive, and the wind pressure displayed on the locomotive instrument panel. This method has certain limitations. First, because the crew members need to deal with multiple information sources at the same time, they are prone to negligence and may not be able to judge the braking status in a timely and accurate manner, thus affecting driving safety. Secondly, this method relies on the crew members' operating skills and experience. For novice or inexperienced crew members, they may not be able to accurately judge the braking status of the locomotive, which increases safety risks.

[0004] Therefore, the problems or shortcomings of the existing technology in this field limit the safe operation of freight locomotives, and a technical solution is urgently needed to solve these problems. Summary of the invention

[0043] During the operation of freight locomotives, especially when going down long slopes, accurate operation of the braking system is crucial. At present, freight locomotive crews have to perform long slope traction tasks, which require long operation time, many safety risks, and many traction and braking regulations. They must prevent the locomotive from stopping on the uphill slope and losing control on the downhill slope. Therefore, the crew's operating skills are particularly high.

[0044] At present, locomotive crew members mainly rely on experience, the locomotive's running position, and the wind pressure displayed on the locomotive instrument panel to judge whether the locomotive can brake or relieve the pressure. This method has certain limitations.

Second, this method relies on the crew's operating skills and experience. For novice or inexperienced crew, they may not be able to accurately judge the braking status of the locomotive, increasing safety risks.

[0046] Therefore, the problems or shortcomings of the existing technology in this field limit the safe operation of freight locomotives, and a new technical solution is needed to solve these problems.

[0077] In a possible implementation, a specific implementation of a method for using a locomotive brake relief voice prompt device is provided as follows:

[0078] 1. Basic Function Implementation

[0079] 1. Hardware Installation:

[0080] Install an intelligent voice announcer (supporting IP65 protection level) on the side wall of the locomotive cab control console;

[0081] The LKJ junction box is connected to the spare data port of the TAX box, and an independent channel is allocated to collect LKJ real-time data;

[0082] The computer platform is deployed in the equipment cabinet of the driver's cab and communicates with the data terminal box via the CAN bus.

[0083] 2. Data configuration:

[0084] Preset route database, including slope, speed limit, and braking section coordinates (such as a continuous downhill slope with a slope of >3% and a length of >2km);

[0085] Set the braking trigger condition: when the speed is ≥45km / h and the slope is ≥4%, the wind pressure is less than 650kPa for 10 seconds;

[0086] Voice content template: "There is a long downhill slope 1 km ahead, please ease the brakes to a wind pressure of 700kPa."

[0087] 3. Operational verification:

[0088] When the locomotive enters the preset braking section, the computer platform compares the real-time position with the line data and triggers a voice prompt;

[0089] After the crew member operates, the system detects that the wind pressure has recovered to above the threshold and records the "operation completed" status.

[0090] 2. Multi-mode voice prompt expansion

[0091] 1. Classification of alarms:

[0092] Level 1 reminder (pre-judgment stage): gentle voice reminder "Pay attention to the braking area ahead";

[0093] Second level prompt (operation window): urgent voice "immediately release the brake to 700kPa";

[0094] Level 3 alarm (out of limit but no operation): buzzer alarm and send fault code to the ground center simultaneously.

[0095] 2. Multi-language support: The voice library has built-in Chinese, English and minority languages, which are automatically switched according to the crew ID.

[0096] 1. Linkage display:

[0097] When the voice prompt is given, the HMI screen highlights the braking section map and target wind pressure value;

[0098] After the operation is completed, the HMI generates an "operation compliance score" (such as full marks if the response time is ≤ 5 seconds).

[0099] 2. Data Analysis:

[0100] The data storage module records the crew response time and operation results for each prompt;

[0101] The brake trigger threshold is optimized through machine learning algorithms to reduce false alarm rates.

[0102] 4. Design for adaptability to harsh environments

[0103] 1. Anti-interference design:

[0104] The voice announcer has a built-in noise reduction chip, which automatically increases the volume to 120dB when the noise is greater than 85dB;

[0105] The computer platform uses an industrial-grade motherboard with a wide temperature range (-40℃~70℃) to adapt to high-cold or high-temperature lines.

[0106] 2. Redundant communication:

[0107] A dual-channel data link is added between the LKJ junction box and the TAX box, which automatically switches to the backup channel when the main link fails.

[0108] The locomotive brake relief voice prompt device provided in some embodiments of the present application can greatly improve the safety of freight locomotives. Through real-time monitoring and control, it can prevent crew members from making mistakes due to fatigue, distraction or negligence, ensure the accurate operation of the braking system, prevent problems such as stopping on the uphill road and losing control on the downhill road, and improve driving safety.

[0109] In addition, the voice prompt device can also help novice or inexperienced crew members accurately judge the braking status of the locomotive and reduce safety risks. The intelligent voice announcer can broadcast the status information of the locomotive in real time, provide voice prompts, and improve user experience. In addition, the voice prompt device can also be used to remind crew members to perform necessary operations and improve operational accuracy.

[0110] In general, the voice prompt device provided in some embodiments of the present application has broad application prospects in the field of railway transportation technology, has huge market demand, and is expected to promote technological progress and industrial development in related fields.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
