Technical Field
The utility model relates to a cable environment stress screening test equipment specifically is a cable temperature circulation real-time test platform.
Background
The cable environmental stress screening test is an important link of complex product cable production, and mainly applies random vibration, temperature cyclic stress and the like on the cable to identify and eliminate early failure caused by product processes and elements, so as to find and eliminate defects of bad parts, components and processes. The cable temperature cycle test generally needs 80 hours, the time is long, the labor intensity is high, the real-time test of the product cable in the temperature cycle test process cannot be realized at the present stage, and the test process is very complex.
Disclosure of Invention
The utility model discloses a solve the unable real-time problem of going on of current cable temperature cycle test, provide a cable temperature cycle real-time test platform.
The utility model discloses an adopt following technical scheme to realize: cable temperature cycle real-time test platform, including the integration workstation, the integration workstation is connected to determine module and relay subassembly respectively, determine module and relay subassembly all locate the bottom plate subassembly on, the bottom plate subassembly is equipped with a plurality of groups of wiring port able to programme, every group wiring port number able to programme is two, wiring port able to programme is connected to the cable that awaits measuring, the cable that awaits measuring is arranged in the warm damp heat test incasement that becomes, the warm damp heat test incasement that becomes is equipped with temperature sensor, temperature sensor even gets back to the integration workstation.
When the cable temperature cycle real-time test bench works, after a plurality of cables to be tested are connected to each group of programmable wiring ports, temperature cycle stress is applied to the cables by using the temperature-to-humidity-heat test box, namely the temperature changes circularly in a certain range, the programmable wiring port is used for marking the group number of the cable to be tested, and feeds back to the integrated workstation, the integrated workstation controls different relay arrays of the selective relay assembly, selects different core wires of cables of different groups for testing, the detection assembly provides a constant current power supply required by detection and applies the constant current power supply to the cables, and meanwhile, collecting the resistance information of the cable core wire, converting the resistance information into a voltage signal, and transmitting the voltage signal back to the integrated workstation, wherein the integrated workstation judges whether the resistance value of the cable core wire to be tested meets the standard according to a set voltage signal standard value, so that whether the connection value and the insulation value of the cable to be tested are qualified or not is determined.
According to the working process, the detection assembly comprises a corresponding power supply module, a control unit module, a data acquisition unit, a conversion circuit, a comparison circuit, a photoelectric isolation module and the like, transmission circuits are arranged between the detection assembly and the programmable wiring port and between the detection assembly and the relay assembly, the integrated workstation samples and processes data through a set program, and a processing result can be output in a form of displaying or printing a test report form through a display screen and storing the data in a hard disk. The above circuit design and programming can be easily implemented by those skilled in the art according to the description of the operation process.
The utility model has the advantages as follows: the experiment for monitoring the temperature cycle of the cable in real time is realized by using the reasonably designed test equipment. The utility model discloses the automation level is high, and the cost of labor is low, and scalability is strong, can test the different complicated cable of multiunit simultaneously to real-time supervision and record and output test data in the longer cable temperature cycle experiment of time.

Fig. 1 is a schematic structural view of the present invention;
in the figure: the system comprises a working station 1, a detection component 2, a relay component 3, a bottom plate component 4, a programmable wiring port 5, a programmable wiring port 6, a cable to be tested 7, a temperature-humidity-heat test box 8 and a temperature sensor 9.
Detailed Description
Cable temperature cycle real-time test platform, including integration workstation 1, integration workstation 1 is connected to determine module 2 and relay assembly 3 respectively, determine module 2 and relay assembly 3 all locate on bottom plate subassembly 4, bottom plate subassembly 4 is equipped with a plurality of groups wiring port 5 able to programme, 5 quantity of wiring port 5 able to programme of every group are two, wiring port 5 able to programme is connected to the cable 7 that awaits measuring, the cable 7 that awaits measuring is arranged in temperature change damp heat test box 8, be equipped with temperature sensor 9 in the temperature change damp heat test box 8, temperature sensor 9 links back to integration workstation 1.
In the specific implementation process, the integrated workstation 1 can be realized by adopting a PC, and the detection component 2 is realized by adopting PCI-1752, PLC-818HD and the like. The constant current power supply adopts a +5VDC, +12VDC, 100mA constant current power supply. The program has the capability of dynamically defining the control logic, only corresponding control logic configuration files need to be defined in different tests, the control logic configuration file of each set of cable is an independent file, and the program automatically detects the cable group number according to the connection state of hardware and executes different control actions on the corresponding control logic. And even if the cable group is increased, the program is not required to be modified, and the detection can be finished only by increasing the corresponding control logic file and according with the format requirement.
