Example 2
Different from embodiment 1, in this embodiment, a mode of observing an indicator light with naked eyes is not used to identify PoE devices with power supply failure, in this embodiment, all PoE devices to be tested are arranged at two ends of a power receiving load in parallel, each first switch is arranged on a corresponding branch, and a mode of determining whether all PoE devices to be tested successfully supply power to the power receiving load is, for example:
a current sensor is arranged on a trunk circuit where the power receiving load is located, if the current value detected by the current sensor reaches a preset threshold value, all the PoE equipment to be detected successfully supplies power to the power receiving load, otherwise, all the PoE equipment to be detected successfully supplies power to the power receiving load; or the like, or a combination thereof,
and an electrical signal detector is arranged on each branch, if the electrical signal detector on each branch detects an electrical signal, all PoE equipment to be tested successfully supplies power to the powered load, otherwise, all PoE equipment to be tested successfully supplies power to the powered load. In this embodiment, in order to indicate the orientation of the PoE device that was not successfully powered, the production testing system further includes a second portal module electrically connected to each power receiving module through a third switch (switch N2 in fig. 1) and configured to be electrically connected to a Ping tester (the Ping tester may be replaced by another instrument signal generator) through a data interface; and carrying out Ping test on the IP address of the PoE equipment by using the Ping test machine, if the IP address Ping of the PoE equipment is on, the PoE equipment is successfully powered, otherwise, the PoE equipment is a power failure fault point. Generally, the PoE device itself has an indicator lamp indicating the Ping connected state, thereby identifying whether the power supply of the PoE device is successful or not.
In less than all PoE devices under test (e.g. PoE device N in fig. 1) 11 To N ij ) If the power supply to the power receiving load is successful, the main control module controls the second port module to send the data of the Ping test machine to each PoE device (namely PoE device N) corresponding to the first power receiving module 11 To N 1j ) If PoE device N 11 To N 1j If the IP addresses of the first network port module are all Ping, the second network port module is controlled to send the data of the Ping test machine to the PoE devices (namely, poE device N) corresponding to the second power receiving module 21 To N 2j ) Meanwhile, the first network port module is controlled to send the data of the instrument signal generator to each PoE device (namely PoE device N) corresponding to the first power receiving module 11 To N 1j ). In order to realize that the main control module controls different data to be sent to different power receiving electronic modules, a unit switch (not shown) is also arranged to be connected with the first internet access module except the second switch N1 to be respectively connected with different power receiving electronic modules, and the main control module controls the circulation condition of the data of the instrument signal generator to each power receiving electronic module through the control unit switch; similarly, a unit switch (not shown) is further provided in addition to the third switch N2 for connecting to the second portal module to connect to different power receiving modules, and the main control module controls the flow of the data of the Ping test machine to each power receiving module through the control unit switch.
The method for testing whether the PoE equipment is successfully powered one by utilizing the Ping testing machine comprises the following steps: the first switch is an electronic controllable switch, and the main control module is configured to control the first switch to be switched on or switched off; taking the first power receiving module in fig. 1 as an example, the switch N1 is first controlled to be closed, and then the switch K is controlled 11 Closed, other switch K 12 -K 1j Disconnection, if PoE equipment N 11 Ping is on, the power supply is judged to be successful, otherwise, the power supply is failed; then, the switch K is controlled 11 、K 13 -K 1j Switch off, control switch K 12 And closing, and circulating until all PoE equipment connected with the first power receiving electronic module is traversed.
If the PoE device is not Ping-enabled, the PoE device is replaced with a new PoE device until all the PoE devices of the power receiving electronic unit are Ping-enabled, and then as in embodiment 1, the power receiving electronic unit is connected to the first port module for data testing, and simultaneously the next power receiving electronic unit is connected to the second port module for Ping testing.
Example 3
The difference from embodiment 2 is that, if the IP addresses of all PoE devices corresponding to a first power receiving module are not all Ping-pass, the main control module controls the second port module to send data of the Ping test machine to all PoE devices corresponding to a next power receiving module, so as to screen out all Ping-pass power receiving modules; and the master control module controls the first network port module to sequentially send the data of the instrument signal generator to all the PoE equipment corresponding to all the screened Ping-through power receiving electronic modules, and performs a Ping test again after replacing all the PoE equipment at the power failure fault points in the power receiving electronic modules which are not all Ping-through until all the PoE equipment of the power receiving electronic modules are all Ping-through.
Compared with embodiment 2, in this embodiment, it is not necessary to sequentially update the power receiving electronic modules one by one until all power supply succeeds, but all power receiving electronic modules in Ping are screened out (not taking the power receiving electronic modules as a unit), and the cross-submodule selects the PoE device with unsuccessful power supply, such as the PoE device N 13 、N 22 、N 35 、N 41 And then, performing power supply test on the updated new equipment, and after the success, performing data test on all power receiving electronic modules which are not all Ping powered on when the primary screening is completed.
Example 4
Unlike the previous embodiments, in the initial stage of the test, the power receiving module is used as the test unit in the present embodiment, for example, the switch K is closed first 11 、K 12 To K 1j And connecting the PoE device with the Ping test machine, and if the PoE device N is connected with the PoE device N 11 、N 12 To N 1j When Ping is on, the circuit between the pin and the testing machine is cut off, the pin and the instrument signal generator are connected, and the switch K is closed 21 、K 22 To K 2j And the testing device is connected with the Ping testing machine, namely the next testing unit performs power supply testing, and the previous testing unit performs data testing, so that the testing efficiency is improved.
If, for example, K 24 If not, replacing the PoE equipment with new PoE equipment and communicating the PoE equipment with a Ping test machine until the newly replaced PoE equipment is Ping communicated;
or, mixing K 24 Recording the data to a list which is not Ping passed, then directly carrying out Ping test on the next test unit until all test units are Ping tested, screening all Ping passed test units to enter a data test stage, screening PoE equipment which is not Ping passed to update, carrying out Ping test on the PoE equipment, and preferentially carrying out data test on all Ping passed test units.
Example 5
In one embodiment of the invention, the power receiving modules of the production and measurement system are configured in a building block type building mode, wherein the power receiving modules of the production and measurement system can be built by different power receiving modules, and the different power receiving modules are provided with different numbers of first switches, namely can be connected with different numbers of PoE equipment; if the failure rate of the performance test of the PoE equipment obtained by the test is greater than a preset first proportional value, the small-specification power receiving sub-module (receiving a smaller number of PoE equipment) can be replaced to reduce the probability that all PoEs (power over Ethernet) received by the power receiving sub-module are not successfully powered; if the fault rate of the PoE device performance test obtained through the test is smaller than the preset second ratio value, large-size power receiving sub-modules (connected with a larger number of PoE devices) can be replaced to increase the number of PoE devices synchronously used for power supply test and data test at a time, wherein the first ratio value is larger than or equal to the second ratio value, and the fault rate of the PoE device performance test can be the ratio of the number of PoE devices which do not pass the Ping test to the total number of the PoE devices which do the Ping test, or the ratio of the number of the PoE devices which do not pass the whole production performance test to the total number of the PoE devices which do the production test.
