With the development of high and new technology, the progress of the transportation industry has not fallen, and the development of railways in our country has become faster and faster. From the original green leather trains driven by coal burning energy, to new energy sources such as electricity now Powered high-speed rail, nowadays China's transportation is in all directions, and the railway runs through the entire mainland of China. Every day, tens of millions of people use railways as a means of transportation to travel between provinces and cities. Behind the two huge projects of railways and trains, you must not know how many temperature and humidity sensors are used ?
For the manufacture of trains, an ordinary moving car will use hundreds of temperature and humidity sensors , and every part of the train will play its special role during the running of the train. Of course, during the operation of the train, the devices in the control room will generate heat due to long-term power, and the wheels will also generate heat due to friction with the track. The temperature and humidity sensors in these parts will be monitored. The value detected by the temperature and humidity sensor is used to observe whether the train fails during operation. When the temperature detected by a certain temperature and humidity sensor is higher than the set temperature value, the system will feedback the data to the monitor in the train monitoring room. , Remind the trainer to deal with; if the wheel temperature is too high, the train will automatically speed limit, wait for the temperature to drop before proceeding to the next step.
The temperature and humidity in the cabin will also change from high to low due to changes in the number of people. The temperature and humidity sensor will automatically adjust the temperature and humidity in the cabin based on the monitored temperature and humidity value, allowing passengers to ride in a quiet and comfortable environment.
The construction of railway viaducts is generally cast directly with concrete. The strength and hardening results of concrete are related to the temperature and humidity of the concrete. Therefore, one or more temperature and humidity sensors will be embedded in the initial pouring to monitor this piece. The temperature and humidity value of concrete also provides a parameter reference and basis for future railway bridges' firmness and subsequent maintenance and repair.
In fact, in the construction and operation of railways and trains, not only temperature and humidity sensors can be used to their fullest, but also many pressure sensors and speed sensors, etc., play their special roles in the train industry.
