Volume size and POE switch tests jig 100 be inserted into quantity be determined.Controller can be but not limited to microcontroller or
Person's PLC programmable controller.
Specifically, the temperature of the temperature sensor real-time detection POE switch tests jig 100 by temperature control device 28,
And it is sent to controller, to which controller can control the rotating speed of each radiator fan motor according to temperature height, reach heat dissipation speed
The effect of rate dynamic control.Heat radiation performance simultaneously, effectively reduces energy consumption.
Test cabinet 200 further includes the Air Filter 29 being installed on metal cabinet 22 in one of the embodiments, dust-proof
Net 29 is matched with vent locations.It is appreciated that Air Filter 29 can be metal dust net, and can also be plastic dust net, it can
To be determined according to heat dissipation performance, the cost of manufacture etc. of test cabinet 200;Its shape can be but not limited to circle or rectangular,
Concrete shape can be determined according to the shape of ventilation hole.It can prevent dust from largely entering test cabinet by the way that Air Filter 29 is arranged
200 internal controls influence test and heat dissipation performance.
1 to Figure 13 is please referred to Fig.1, the embodiment of the present invention also provides a kind of POE switch test equipments 300, including above-mentioned
Test cabinet 200 and at least one above-mentioned POE switch tests jig 100.
The use it is appreciated that above-mentioned test cabinet 200 and POE switch tests jig 100 can form a complete production network, such as
It is fixed on test cabinet 200 to load a certain number of POE switch tests jigs 100.In this way, being exchanged by set of POE
Machine test equipment 300 can quickly carry out above-mentioned test.The low manufacture cost of POE switch test equipments 300, test effect
Rate is high, and scalability is preferable.
For example, as shown in figure 12, when test separate unit is tested POE interchangers 20, for being tested the port of POE interchangers 20 not
The scene of (VLAN) in the same LAN.Each port of tested POE interchangers 20 can be connected with cable (such as schemes
Middle double arrowed line) to any one signal port of a POE switch tests jig 100, another signal port passes through cable
Monitoring terminal 30 is connected to be tested such as PC machine or Ethernet send and receive packets instrument.Such as POE interchangers 20 are tested with 8
When a port, 8 POE switch tests jigs 100 can be selected, i.e., is inserted into 8 POE switch tests jigs 100 respectively and arrives
On 8 horizontal slotting guide rails on metal bracket 24.
For another example for be tested the ports of POE interchangers 20 in the same LAN (VLAN) scene, be tested POE
The a port of interchanger 20 can be connected to a signal port of a POE switch tests jig 100, quilt by cable
Remaining port for surveying POE interchangers 20 is sequentially connected the signal port of each POE switch tests jig 100 by cable.Specifically
, be tested POE interchangers 20 for example with 8 ports when, connection type as shown in fig. 13 that may be used and tested:By end
Mouth 1 and 2,3 and 4,5 and 6,7 and 8 is arranged at the same LAN (VLAN).In this way, being controlled by being inserted into 5 POE switch tests
It can carry out test on 5 horizontal slotting guide rails on tool 100 to metal bracket 24.Test process for example can be by PC machine or with
Too net give out a contract for a project instrument be dealt into the other end PC machine or Ethernet send and receive packets instrument hair, packaging (ping) test can test it is tested
The ethernet link performance of POE interchangers 20;Using the POE switch tests for including above-mentioned POE switch tests jig 100
Equipment 300, you can not only test Ethernet data switching performance to reach simultaneously, but also the mesh of electric power signal load capacity can be tested
's.
4 are please referred to Fig.1, the embodiment of the present invention also provides a kind of POE switch tests system 400, including above-mentioned each implementation
Tested POE interchangers 20, monitoring terminal 30 in example and above-mentioned POE switch test equipments 300.
By applying above-mentioned POE switch test equipments 300, POE switch tests system 400 can be in batches to tested
POE interchangers 20 are tested, and the production test cost of tested POE interchangers 20 can be greatly reduced.
Each technical characteristic of above example can be combined arbitrarily, to keep description succinct, not to above-described embodiment
In each technical characteristic it is all possible combination be all described, as long as however, the combination of these technical characteristics be not present lance
Shield is all considered to be the range of this specification record.
Several embodiments of the invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Range.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
