Locomotive driver display unit with low temperature preheating function

Abstract

The invention discloses a locomotive driver display unit with a low-temperature pre-heating function. The locomotive driver display unit is provided with a display module with a liquid crystal display and an automatic temperature controlling module for providing the thermal insulation function for the display module, wherein the automatic temperature controlling module is provided with a temperature sensor, a heating film, a relay and a single chip micro-computer; the temperature sensor is used for sensing environmental temperature and generating and outputting a temperature signal; the heating film is fixed on the liquid crystal display; the relay is connected with the heating film and used for controlling works of the heating film; the single chip micro-computer is connected with the temperature sensor and the relay and used for controlling connection and disconnection of the relay according to the temperature signal uploaded by the temperature sensor and the pre-set temperature threshold so as to control the works of the heating film; and the single chip micro-computer is provided with an on-chip register. According to the invention, the event that application of the driver display unit is not beyond application conditions is ensured; various requirements, especially temperature environment requirements, can be satisfied; device failure and function loss occurring frequently are greatly reduced; and the practical service life of the driver display unit is greatly increased.

Description

technical field [0001] The invention relates to a locomotive driver display unit, in particular to a locomotive driver display unit with a low-temperature preheating function. Background technique [0002] The locomotive driver's display unit (DDU) is a platform for information interaction between the locomotive driver and the on-board equipment, and is an important part of the locomotive network monitoring and management system. With the rapid development of railways, the requirements for the quality of on-board electronic products are becoming more and more stringent, and the application environment conditions are also getting higher and higher. At present, most of the traditional driver display units can no longer meet the needs of future railways. Therefore, it is urgent to design a A locomotive driver display unit capable of maintaining high-efficiency and high-quality work under severe conditions such as high cold and low temperature, so as to provide effective informa...

Problems solved by technology

[0004] Because the existing display unit does not judge whether the use conditions of the driver display unit are satisfied, the driver display unit is often put into work when the working conditions are not met. Because the ambient temperature is too low, the power supply and other functions in the unit The template does not work properly, so there will often be device failures and even loss of functionality, seriously shortening the actual life of the unit
