For achieving the above object, technical scheme of the present invention is, an electronic product aging testing system, is characterized in that: described test macro is that background system control PLC module connects respectively thermal module, humidity module, temperature adjustment module, moisture adjustment module, Timing module; Timing module connects product to be measured; After signal source module and PLC module communication, be connected on product to be measured.
Described PLC module gathers the temperature in burn-in chamber, humidity information by thermal module, humidity module and regulates the temperature humidity guaranteeing in burn-in chamber in specialized range by temperature adjustment module, moisture adjustment module.
Described background system calculates contrast by the output signal of the input signal of signal source module and product to be measured, judges that product is defective after output signal exceeds threshold.
Described background system is arranged in the pulpit on the control table outdoors that is arranged at aging electronic product room.
Described thermal module, humidity module, temperature adjustment module, moisture adjustment module, Timing module and signal source module are arranged in aging room of electronic product.
An electronic product aging testing system, owing to adopting above-mentioned structure, the invention has the advantages that: 1, room design temperature, humidity range are wide, within the scope of normal temperature～85 ℃, humidity 0%-100%RH is can arbitrary continuation adjustable; 2, system protection is multiple functional, can guarantee safety and stability failure-free operation test; 3, according to the performance of product, carry out signal input and time demand, meet the accuracy of electronic product on-line testing; 4, effectively improve the reliability of electronic product.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation;
Fig. 1 is a kind of electronic product aging testing system of the present invention structural representation;
In Fig. 1,1, background system; 2, PLC module; 3, thermal module; 4, humidity module; 5, temperature adjustment module; 6, moisture adjustment module; 7, Timing module; 8, signal source module; 9, product to be measured.
Embodiment
The present invention includes background system 1 is computing machine, PLC module 2, thermal module 3, humidity module 4, temperature adjustment module 5, moisture adjustment module 6, Timing module 7, signal source module 8.
Background system 1 is supervisory layers.PLC module 2 is key-courses.Thermal module 3, humidity module 4, temperature adjustment module 5 are carried out on-site data gathering jointly with moisture adjustment module 6, Timing module 7, signal source module 8, form field layer.
Specifically as shown in Figure 1, the present invention is that background system 1 control PLC module 2 connects respectively thermal module 3, humidity module 4, temperature adjustment module 5, moisture adjustment module 6, Timing module 7; Timing module 7 connects product 9 to be measured; After signal source module 8 and 2 communications of PLC module, be connected on product 9 to be measured.
PLC module 2 gathers by temperature, humidity information in thermal module 3,4 pairs of burn-in chambers of humidity module and regulates the temperature humidity guaranteeing in burn-in chamber in specialized range by temperature adjustment module 5, moisture adjustment module 6.Background system 1 calculates contrast by the output signal of the input signal of signal source module 8 and product to be measured 9, judges that product is defective after output signal exceeds threshold.Background system 1 is arranged in the pulpit on the control table outdoors that is arranged at aging electronic product room.Thermal module 3, humidity module 4, temperature adjustment module 5, moisture adjustment module 6, Timing module 7 and signal source module 8 are arranged in aging room of electronic product.
Temperature information in background system 1 Real-time Collection aging room of electronic product and temperature parameter, the humidity parameter of humidity information and setting contrast, after exceeding setting range, control temperature adjustment module 5 or moisture adjustment module 6, when the temperature and humidity in electronic warehouse regulates.The output that the stimulus part of the electronic product simultaneously connecting according to background system and electronic product show calculates contrast, carries out the numerical value of conditioning signal input.
Background system 1 centered by computing machine, by communication network, be connected with PLC module 2 and with signal source module 8, form a network.The various information that background system 1 gathers PLC module 2 (temperature in burn-in chamber, humidity and aging in the real time data of electronic product output) preserve and with parameters contrast, carry out respective handling.PLC module 2 is mainly comprised of PLC, the parameter of environmental system is arranged, and information PLC being gathered by communication interface uploads to background system 1.The temperature parameter that thermal module 3 arranges according to PLC, regulate in real time.When thermal module parameter is low, move when the PLC parameters.Real time temperature in the burn-in chamber that temperature adjustment module 5 is set compares, the temperature in environment higher than set parameter time carry out corresponding cooling work.In the humidity parameter 40-60%RH scope that moisture adjustment module 6 arranges according to PLC, compare with the real-time humidity in aging room of electronic product, the humidity in environment lower than set parameter time carry out corresponding humidification work.Timing module 7 according to PLC module all the digestion time of electronic product setting set, regulate.Signal source module 8 carries out the lasting input of various signals according to the product demand in aging, by the numerical value that calculates output signal of interiors of products, contrast and regulate with the numerical value of standardized product.
