一种新型的ABS电磁阀响应时间的检测装置
摘要：
本发明涉及电磁阀的测试技术领域，旨在提供一种新型的ABS电磁阀响应时间的检测装置，该装置包括设在汽车轮缸上的电磁阀，这8个电磁阀相互独立互不影响，分别并联接入各自的汽轮轮缸中；各自的电磁阀电流传感器也并联接入相应的电磁阀，所述8个电磁阀电流传感器与电流采集卡相连，将获得的电流信号分别通过电流采集卡输入到后台的电脑系统中分析。而本发明是通过采集电磁阀的开启或关闭时电流变化的时间来判断阀的好坏，电流采集时间可达5微秒（μs），通过实验数据分析，该装置次品检测率可达到100%。
摘要（英）：

The invention relates to the technical field of electromagnetic valve detection, and the purpose of the invention is to provide a novel ABS electromagnetic valve response time detection device. The device comprises eight electromagnetic valves arranged on automobile wheel cylinders, and the eight electromagnetic valves are independent from one another, not affecting one another, and are respectively connected in parallel with the respective automobile wheel cylinders; electromagnetic valve current sensors are also respectively connected in parallel with the electromagnetic valves, the eight electromagnetic valve current sensors are connected with a current acquisition card, and acquired current signals are respectively inputted into a background computer system via the current acquisition card to be analyzed. By acquiring current changes as the electromagnetic valves are opened or closed, the device judges whether the valves are in the good or bad condition, the current acquisition time can be up to 5 microseconds (Mu s), and by analyzing experimental data, the defective product detection rate of the device can reach 100 percent.
