Embodiment
To be applied to automatic switching test system specific embodiments of the present invention is described below.
As shown in Figure 1, automatic switching test system comprises main control computer 106, tested machine 108, test card for computer 109 and realizes the device 107 of main control equipment control multiple devices, wherein, COMPUTER DETECTION is placed in the tested machine, and main control computer connects tested machine by the device of realizing many controlled devices of main control equipment control.
The device of realizing many controlled devices of main control equipment control comprises multiple signals control module 101, relay control module 102, mainboard switch control module 103 and mainboard RESET control module 104 and power supply detection module 105.From the control command input multiple signals control module of main control computer, multiple signals control module 101 is at first isolated its photoelectricity, judges that then this order is which kind of order of the tested machine of which platform of control.If this order is sense command, the multiple signals control module is then wanted gating power detection module 105, and power supply detection module 105 should tested dynamo-electric source status information send main control computer to; If this order is 220V power supply power-on and power-off control commands, 101 of multiple signals control modules are wanted relay gate control module 102, the 220V power supply power-on and power-off of the corresponding tested machine of relay control module 102 controls; If open and close machine control command, 102 of multiple signals control modules are wanted gating mainboard PSW control module 103, and the signal that is sent switching on and shutting down by mainboard PSW control module 103 is to corresponding tested machine; If reset control command, 102 of multiple signals control modules are wanted gating mainboard RESET control module 104, and mainboard RESET control module 104 will be sent reset signal to corresponding tested machine.
And above-mentioned device can be realized by coding and multipath conversion technology.Shown in the coding control structure figure of Fig. 2, export 11 road signals from the control command of main control computer through the D/A transition card, 11 tunnel signal is divided into three groups after photoelectricity is isolated, and one group is that 4 paths that are used for the tested machine of gating are selected signal CHAN A～D; One group is respectively 3 tunnel control signals such as PSW_TRL motherboard power supply control signal, RESET_CTRL reseting controling signal and 12JD_CTRL relay control signal; One group is 4 tunnel decoded signals, and this 4 tunnel decoded signal signal PSW_SEL, gating of being converted to gating PSW switch by code translator reset switch signal RET_SEL, relay gate switch signal 12JD_SEL, be used for the signal 5V_SEL of gating 5V multi-way switch and be used for 5 kinds of CE signals such as signal 5VSB_SEL of gating 5VSB multi-way switch.
When 12JD_SEL signal gating relay multicircuit switch, 12JD_CTRL relay control signal and channel selecting signal are sent into the relay multi-way switch, and export 16 group relay control signals through multipath conversion, this 16 tunnel control signal latchs, photoelectric coupling circuit exports relay to after amplifying, and input signal is 1 relay closes.Relay one closure, the power lead of controlled device has just been connected, and controlled device powers on.
When PSW_SEL signal gating PSW multicircuit switch, PSW_CTRL power control signal and channel selecting signal are sent into the PSW multicircuit switch, and export 16 group system switch controlling signals through multipath conversion, this 16 tunnel control signal is sent into photoelectric coupling circuit and is amplified output.
When the RET_SEL signal gating resets the multipath conversion device, RESET_CTRL reseting controling signal and channel selecting signal are sent into the multipath conversion device that resets, and export 16 group system switch controlling signals through multipath conversion, this 16 tunnel control signal is sent into photoelectric coupling circuit and is amplified output.
When 5V_SEL signal gating 5V multipath conversion device, tested machine motherboard power supply signal 5V from test card for computer sends into 5V multipath conversion device through photoelectrical coupler, multi-way switch will be exported the power state information of tested machine, and deliver to main control computer after the conversion of A/D transition card.
And, when 5VSB_SEL signal gating 5VSB multipath conversion device, power supply signal 5VSB from the tested machine 220V of test card for computer sends into 5VSB multipath conversion device through photoelectrical coupler, multi-way switch will be exported the status information of the motherboard power supply of tested machine, and deliver to main control computer after the conversion of A/D transition card.
Need to prove that 11 road signals of the output of the D/A card of main control computer are respectively 5V or 0V, represent 5V and 0V with 1 and 0 of logic here.
And 4 paths select signal can form tetrad, and it can represent 0000～111116 numeral, so this binary number is changed by multi-way switch, promptly can select one of 16 passages.Such as, tetrad is 0000, then selecting first passage, tetrad is 0100, then selects the five-way road; 1 and 0 state of 3 tunnel control signals control respectively 220V power-on and power-off, the system start-up of corresponding controlled device and close, reset effective and invalid, this expression main control computer sends and will control the mode that tested machine is taked; Output is used to control multi-way switch working chip gating signal to 4 tunnel decoded signals through code translator, if code translator adopts 4-10 decoding, so, the output of 4 decoded signals can be controlled 10 multi-way switchs respectively, can control second multi-way switch such as 0001 after deciphering.
Can obtain according to above analysis, preceding four and back four bit representation main control computers are specified the tested machine of which platform are realized operation in 11 codings, and middle tri-bit encoding represents main control computer specifies which kind of operation controlled device is realized.So this input coding of 11 tunnel can realize adopting any one mode that any controlled device is controlled by this device.Such as 11 codings is 00101000000, then the 220V of the 3rd controlled device of expression control powers on, if system is a power-up state, system will keep the state that powers on, till sending the 220V power supply that coded order 00100000000 turns off this machine, if system is a power-down state, this device is then controlled the relay of controlled device correspondence, connects the power supply of this controlled device; If 11 road codings are 00010010001, then control second controlled device and carry out reset operation.
The present invention can expand to multi-way switch 10, controlling 10 chips with the 4-10 code translator, other parts of system are constant, increase by 5 groups of multi-way switchs again, can control 16 tested machines again, system just can control 32 controlled devices, because every controlled device has 5 kinds of control modes, so also just can realize 32 * 5=160 kind control model.
The present invention realizes by hardware circuit, the reliability of system, stable strong, and cost is low.
The present invention adopts the mode of light-coupled isolation that the circuit of main control computer and tested machine is kept apart, and has avoided crosstalking mutually of system, has improved the anti-interference of system greatly.The present invention can be applied to the computer control field, and above-mentioned only is preferred embodiment of the present invention, all within above-mentioned spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the claim scope of the present invention.
