Application of low/high Temperature Test Chamber in high-low temperature resistance test of ETC vehicle operating system

The ETC vehicle application system is an electronic payment system, which is widely used in expressways and other scenarios to realize electronic toll collection and automatic deduction of vehicle tolls. Since the system needs to operate in different climates and environments, such as high temperature or low temperature environments, high-low temperature resistance tests are required to test the performance and reliability of the electronic components of the system at different temperatures. This kind of test can test the stability and durability of key components such as the motherboard, memory, display, card reader, and communication module of the system, so as to ensure the stability and reliability of the system at different temperatures. In addition, the high-low temperature resistance test can also test the power consumption, heat dissipation, and anti-interference performance of the electronic components of the system at different temperatures, so as to ensure the normal operation and long-term use of the system in different climates and environments.

The high-low Temperature Test Chamber can be used to test the performance and reliability of ETC equipment in different temperature environments in the high-low temperature resistance test of the ETC (electronic toll collection) vehicle application system. The following are the test steps of the high-low Temperature Test Chamber in the high-low temperature resistance test of the ETC vehicle application system:

1. Preparation: Check whether the Test Chamber and temperature controller are working normally, and set the temperature range and heating and cooling rate of the Test Chamber according to the test requirements. Prepare the ETC equipment, paying attention to its size and location.

2. Sample installation: install the ETC equipment to be tested on the vehicle, and place the vehicle in the test box. Pay attention to the position and direction of the vehicle to ensure the accuracy of the test results.

3. Test operation: Turn on the Test Chamber and temperature controller, and set the temperature range and heating and cooling rate of the Test Chamber. Raise the temperature of the Test Chamber to the set temperature range, keep it for a period of time, and then cool down to the set temperature. During the test, record the temperature changes inside the Test Chamber, and pay attention to observe the performance changes of the ETC equipment.

4. Evaluation of test results: After the test, take out the ETC equipment and observe whether there is any change or damage in its appearance and function. At the same time, test and evaluate parameters such as signal strength and communication distance. Through the evaluation of the test results, the tolerance and stability of ETC equipment in high-low temperature environments can be judged.

Beichao reminds you: ETC equipment should be inspected and tested before the test to ensure its normal operation. During the test, the temperature range and heating and cooling rate inside the Test Chamber should be strictly controlled to ensure the accuracy and reliability of the test. At the same time, the Test Chamber should be cleaned and maintained after the test to prolong its service life.
