Problems solved by technology

The whole test process needs to change the voltage 3 times, power on 38 times, power off 38 times, the number of times of power on and off is very large, if several products are added at the same time, it is easy to cause power on and off.
[0005] 3. Voltage conversion is required in the process
The control required by the debugger for the power-on test is "manual", which is unreliable, unstable, and imprecise
Especially during the 0.5h period of power outage, there will be a waste of manpower
If multiple products are arranged to conduct power-on tests at the same time due to node reasons, there may be a phenomenon of neglecting the other, resulting in untimely power-on and power-off, and untimely voltage conversion, resulting in problematic bottlenecks

Abstract

The invention discloses an intelligent power-on system, comprising: a relay control module, a main control module, a PID feedback module, a power supply module, an AD / DA conversion module and a DC regulated power supply; wherein, the main control module includes a display module, Input module and single-chip microcomputer; the single-chip microcomputer transmits the preset voltage signal in the preset digital signal to the AD / DA conversion module, and the AD / DA conversion module converts the preset voltage signal into an analog voltage signal of 0-5V, and converts the 0-5V The analog voltage signal is transmitted to the control port of the DC stabilized power supply; the DC stabilized power supply outputs a 0-35V DC voltage according to the 0-5V analog voltage signal, and outputs the 0-35V DC voltage to the PID feedback module; the PID feedback module takes the The one-seventh voltage signal of the 0-35V DC voltage is sent back to the AD / DA conversion module and converted into a digital signal, and the AD / DA conversion module transmits the digital signal to the single-chip microcomputer. The invention improves the reliability and production efficiency of product power-on.

Description

technical field [0001] The invention belongs to the technical field of long-term power-on test of products, and in particular relates to an intelligent power-on system. Background technique [0002] Most of the complete machine models require a long-term cumulative power-on test to verify the performance of the product, and the power-on test generally has the following characteristics: [0003] First, the duration is long; the power-on time is usually 300h, or longer, to verify the reliability of the product and ensure the quality of the product. For example, the power-on test requires a cumulative power-on time of 300h, power-on at 28V for 150h, and power-on at 33V for 75h. [0004] 2. Frequent on-off times; 8h is a working cycle. At the end of each cycle, the power is off for 0.5h, and a functional test is performed every 4h. The whole test process needs to change the voltage 3 times, power on 38 times and power off 38 times. [0005] Third, the process requires voltage...
