Description
Technical field
The present invention relates to a kind of network phone system (IP phone system), and be particularly related to method of testing and the device that applies to network phone system in a kind of.
Background technology
Due to popularizing of network technology, can realize novel telephonic communication technology by network.And the networking telephone (IP phone) is namely to utilize network to transmit data and audio-visual service, and it has low, the low advantage of setting up cost, easily expanding of conversation cost, is therefore adopted by international business gradually.
Please refer to Figure 1A and Figure 1B, its illustrate is existing network telephone system schematic diagram.Networking telephone host computer system 100 comprises a networking telephone main frame 110 and an electronic installation (electronic device) 120.Basically, electronic installation 120 is for choosing outfit, and it optionally is connected to networking telephone main frame 110, makes networking telephone main frame 120 possess more I/O ports and Presentation Function.
Basically, networking telephone main frame 100 itself has expansion port 112 and can be connected other peripheral unit with 114.And electronic installation 120 can also be connected to networking telephone main frame 110, and electronic installation 120 still has more signal ports, and for example DVI image port one 21,122 and USB port 123,124,125,126, can insert more peripheral unit.
Please refer to Fig. 2, its illustrate is the power supply supply schematic diagram of network phone system.In network phone system 100, it is first that the plug 132 of power supply unit (power adapter) 130 inserts alternating current, and provide direct voltage (for example 48V) to networking telephone main frame 110, and networking telephone main frame 110 is connected to electronic installation 120 via cable (spine cable) 116.Wherein, eight signal line are arranged in cable 116, comprising: 5V holding wire (SP_Vbus_5V), two nothings are used holding wire (none), ground signalling line (GND), signal lines (SP_Vbus_Det), single-wire signal line (1-wire), 48V holding wire (SP_48V) and 48V inverse signal line (SP_48V_Ret).
Basically, electronic installation 120 is the power supply unit of oneself not, so the supply of its power supply all relies on networking telephone main frame 110 and provides the 48V direct voltage to electronic installation 120 via the binary signal line in cable 116 (SP_48V and SP_48V_Ret).
Moreover electronic installation 120 inside also comprise a microcontroller 128 and direct current transducer 127.Direct current transducer 127 receives 48V holding wires (SP_48V) and 48V inverse signal lines (SP_48V_Ret), and be converted to multiple direct voltage (for example+5V ,+3.3V ,+1.8V) other circuit element (not illustrating) in supplies electrons device 120 uses.Moreover microcontroller 128 receives 5V holding wire (SP_Vbus_5V), signal lines (SP_Vbus_Det), single-wire signal line (1-wire) and controls.Wherein, microcontroller 128 is that the 5V that utilizes 5V holding wire (SP_Vbus_5V) to provide is used as its power supply, and utilizes the voltage level on signal lines (SP_Vbus_Det) to judge that whether networking telephone main frame 110 inserts.
Because 130 electric energy that can supply of power supply unit are limited, and networking telephone main frame 110 and electronic installation 120 all can connect a plurality of peripheral cells, so networking telephone main frame 110 must carry out power management effectively.
For instance, power supply unit 130 provides the electric energy of 25W to networking telephone main frame 110, and the expansion port 112 of networking telephone main frame 110 connects first peripheral unit (not illustrating) that consumes electric energy 5W, and expansion port 114 connects second peripheral unit (not illustrating) that consumes electric energy 8W.So the multipotency of networking telephone main frame 100 provides 12W (25W-5W-8W=12W) to electronic installation 120, so networking telephone main frame 110 can utilize electric energy instruction that single-wire signal line (1-wire) the transmits 12W microcontroller 128 to the electronic installation 120.
Perhaps, the expansion port 112 of networking telephone main frame 110 connects first peripheral unit (not illustrating) that consumes electric energy 8W, and expansion port 114 does not connect peripheral unit.So the multipotency of networking telephone main frame 100 is carried 17W (25W-8W=17W) to electronic installation 120, so networking telephone main frame 110 can utilize single-wire signal line (1-wire) to transmit the microcontroller 128 of 17W electric energy instruction to the electronic installation 120.
Perhaps, the expansion port 112,114 of networking telephone main frame 110 does not all connect peripheral unit.So the multipotency of networking telephone main frame 100 is carried 25W to electronic installation 120, so networking telephone main frame 110 can utilize single-wire signal line (1-wire) to transmit the microcontroller 128 of 25W electric energy instruction to the electronic installation 120.
When the microcontroller 128 of electronic installation 120 received different electric energy instructions via single-wire signal line (1-wire), microcontroller 128 must carry out suitable adjustment, otherwise can cause the electronic installation 120 can't normal operation.For instance, when microcontroller 128 receives the instruction of 25W electric energy, can with all DVI port ones 21,122 and USB port 123,124,125,126 all start.When microcontroller 128 receives the instruction of 17W electric energy, the DVI port one 21 of opening section, 122 and USB port 123,124,125,126 only.
By above-mentioned explanation as can be known, because the power supply of electronic installation 120 is controlled by networking telephone main frame 110, therefore, the microcontroller 128 of electronic installation 120 need to be controlled DVI port one 21,122 and USB port 123,124,125,126 according to the electric energy instruction that networking telephone main frame 110 sends.
By above explanation as can be known, electronic installation 120 in the process of production test, the networking telephone main frame 110 of must will arranging in pairs or groups.And, need many extra peripheral units, plug the expansion port 112,114 in networking telephone main frame 110 in the process of test, the electric energy instruction that makes networking telephone main frame 110 produce various numerical value.And the tester namely judges according to the electric energy instruction of different numerical value whether electronic installation 120 correctly controls DVI port one 21,122 and USB port 123,124,125,126.
Yet above-mentioned test process is very complicated and expend time in, and the tester need to constantly plug peripheral unit in the expansion port 112,114 of networking telephone main frame 110 just can carry out the test of electronic installation 120.Therefore, the how more efficient test of carrying out electronic installation 120 is the purpose that the present invention wants to reach.
