Embodiment
In order to realize testing fast and efficiently the POE module in communication equipment, the present invention proposes a kind of novel POE test fixture, its central scope is: cascaded up by I2C by each POE modular jack, when testing, be equivalent to multiple tested POE model calling by the mode of cascade, by the tested POE module (i.e. main POE module) of band management control module MCU perform to itself and and the detection of operating state of other tested POE modules (namely from tested POE module) of its cascade, without the need to additionally increasing control detection module.Main POE module in charge carries out TCP, and all of the port comprising principal and subordinate's module carries out powered device PD detection and power supply management, can realize the compatibility that POE module way is how many.
The invention provides a kind of POE industrial installation device for testing, comprise supply module, at least one road POE socket cascade module and power receiving equipment link block: described POE socket cascade module, comprising at least one for connecting the POE modular jack of tested POE module; Different according to the structure of industrial installation device for testing, the way of the POE socket cascade module that it comprises is different, and POE modular jack included by the POE socket cascade module of every road is also different, and namely connected tested POE module is different; And each POE modular jack all supports the tested POE module of 4 road port/12, road port/8 road ports.The present invention does not limit the number of the way of POE socket cascade module and the POE modular jack included by the POE socket cascade module of every road.Described supply module, is connected with POE socket cascade module, for powering for tested POE module and powered device PD; Described power receiving equipment link block, for providing interface channel for described tested POE module and power receiving equipment.
Below in conjunction with drawings and Examples, the solution of the present invention is further described.
See Fig. 1, it is the POE industrial installation device for testing structured flowchart in the embodiment of the present invention 1.POE industrial installation device for testing in this example comprises supply module, a road POE socket cascade module, power receiving equipment link block; Wherein a road POE socket cascade module comprises 4 POE modular jacks, and 1 POE modular jack connects main tested POE module, 3 POE modular jacks connections from tested POE module, and each POE modular jack is formed by the cascade of I2C bus.Because each POE modular jack all supports the tested POE module of 4 road port/12, road port/8 road port, POE industrial installation device for testing so in this example adopts 19 cun of standard 1U cabinets in the design process, limit by Cabinet Size, the power receiving equipment link block RJ45 interface provided in the panel of each industrial installation device for testing only has 48, namely can only test 48 road POE ports at every turn, that is, in the tested POE module of maximum 48 road ports can only tested in a road POE socket cascade module of synchronization; Now POE modular jack all connects the tested POE module of 12 road ports.
In addition, in order to judge the operating state of tested POE module in test process more intuitively, in the POE current supply circuit of this example, have also been devised indicating lamp module, described indicating lamp module connects the tested POE module in supply module and POE socket cascade module respectively; POE port one_to_one corresponding in each indicator light in described indicating lamp module and each tested POE module, when in the POE socket cascade module of described master tested POE module controls place, tested POE module is to supplying power for powered device, described each indicator light is used for whether completing by the current supply circuit of power receiving equipment the test result information that lighting indicates corresponding POE port.Operating personnel can not pass through serial ports, directly observe this status indicator lamp and judge that whether tested each road of POE module port of powering is in running order.If power supply port is working properly, then lights corresponding port indicator light, if operation irregularity, then glimmer with alarm.The indicator light of each POE module is independent, and selects direct insertion indicator light, and convenient operation personnel pipe is observed, in order to avoid cause erroneous judgement.This example is also provided and is shown test results by test terminal, tested POE module will be led by universal asynchronous receiving-transmitting UART interface connecting test terminal, collect POE port information and the test result information of all tested POE modules in the POE socket cascade module of place, test result information is outputted to test terminal and shows.
Supply module in this example comprises 48V power supply and 12V power supply; Wherein, 48V power supply is mainly used in as tested POE module for power supply, can select to be tested tested POE module by main tested POE module polls mode, thus the requirement reduced power supply power, also can test all tested POE module in place cascade POE jack module simultaneously.12V power supply is for for being the device on whole POE industrial installation device for testing and some chip power supplies in POE module, and belong to system power supply, power consumption is lower.
See Fig. 2, it is the POE industrial installation device for testing structured flowchart in another embodiment of the present invention.POE industrial installation device for testing in this example comprises supply module, two-way POE socket cascade module, power receiving equipment link block; Wherein every road POE socket cascade module comprises 4 POE modular jacks, and 1 POE modular jack connects main tested POE module, 3 POE modular jacks connections from tested POE module, and each POE modular jack is formed by the cascade of I2C bus.Because each POE modular jack all supports the tested POE module of 4 road port/12, road port/8 road port, the detection of the POE test fixture maximum support 96 road POE module so in this example; But adopt 19 cun of standard 1U cabinets in the design process, limit by Cabinet Size, the power receiving equipment link block RJ45 interface provided in the panel of each industrial installation device for testing only has 48, namely can only test 48 road POE ports at every turn, that is, in the tested POE module of maximum 48 road ports can only tested in a road POE socket cascade module of synchronization; Now POE modular jack all connects the tested POE module of 12 road ports.Therefore, in order to realize testing more fast and efficiently, industrial installation device for testing have also been devised selector switch module in this example, comprise button diverter switch and relay, for switching between two-way POE socket cascade module and power receiving equipment link block, thus 48 POE module testings in a road POE socket cascade module automatically switch to the test to 48 POE modules in a remaining road POE socket cascade module after completing.
In order to ensure long-term stability, the reliably working of whole industrial installation device for testing, need the durability considering POE modular jack in the design process, so can consider in this example to be optimized the structure of socket and material.
POE industrial installation device for testing in this example, both may be used for fixedly being welded the test of POE module, also may be used for the POE module testing of plug-in, for these two kinds of POE modules, only need the POE socket on industrial installation device for testing to be replaced by the socket corresponding with POE module.Therefore, the POE test fixture in this example is raised the efficiency for the batch production of the communication equipment of band POE function, improves first-pass yield, is with a wide range of applications.
