接下来以具体实施例说明本申请的技术方案。Next, the technical solution of the present application is described with specific embodiments.
实施例1Example 1
如图1所示，本实施例的多通道输出与监控的程控电源板，包括电源输入接口100、电源输出模块200、采样模块300和电源输出接口400。As shown in FIG. 1 , the multi-channel output and monitoring programmable power supply board of this embodiment includes a power input interface 100 , a power output module 200 , a sampling module 300 and a power output interface 400 .
本实施例的多通道输出与监控的程控电源板，主要用于对一些外部被测设备检测时供电以及对电压电流的监控。在进行检测时，该电源板会被插在一个底板上，底板为主要进行测试用的一块主板，底板上设置有和电源输入接口100匹配的插槽，通过电源输入接口100插入后，底板为该电源板供电，电源板的电源输出接口400则用于和需要检测的外部被测设备连接，通过该电源输出接口400为外部被测设备供电，同时完成相应的测试操作。The multi-channel output and monitoring program-controlled power board of this embodiment is mainly used for supplying power to some external devices under test and monitoring voltage and current during the detection. During the detection, the power board will be inserted into a base plate, which is a main board mainly used for testing. The base plate is provided with a slot matching the power input interface 100. After the power input interface 100 is inserted, the base plate supplies power to the power board. The power output interface 400 of the power board is used to connect to the external device under test that needs to be detected, and the external device under test is powered through the power output interface 400, and the corresponding test operation is completed at the same time.
上述的外部被测设备在本实施例中主要是硬盘，例如固态硬盘等需要进行外接测试的设备。In this embodiment, the external device under test is mainly a hard disk, such as a solid state disk, or other device that needs to be externally tested.
其中，所述电源输出模块200和所述电源输入接口100之间除了供电线路外，还通过I2C总线连接，并根据所述I2C总线传输的指令进行输出电压的控制。如前述所述，该电源板是插在一个底板上的，底板上设置有控制芯片和总线等电子单元，因为本实施例的电源输出模块200通过I2C总线和底板连接，因此可以接收到来自底板的控制信号，因为针对硬盘的偏拉测试时，存在通过调整电压，来测试硬盘是否处于正常工作状态的操作，同时针对不同的硬盘，其所需要提供的电压也不同，而本申请通过I2C总线实现了通过简单的程序就可以控制电源板进行电压的变化。Among them, in addition to the power supply line, the power output module 200 and the power input interface 100 are also connected through the I2C bus, and the output voltage is controlled according to the instructions transmitted by the I2C bus. As mentioned above, the power board is inserted into a base plate, and the base plate is provided with electronic units such as a control chip and a bus. Because the power output module 200 of this embodiment is connected to the base plate through the I2C bus, it can receive the control signal from the base plate. Because when testing the bias pull of the hard disk, there is an operation of adjusting the voltage to test whether the hard disk is in a normal working state. At the same time, for different hard disks, the voltage required to be provided is also different. The present application realizes that the power board can be controlled to change the voltage through a simple program through the I2C bus.
而为了控制电压和电流采样精度，具体而言，所述电源输出模块还通过电源通道开关设置不同的电流采集档位和所述采样模块300连接；所述电源通道开关用于控制所述电源输出模块的各路电源输出通道输出的电流的档位，不同档位能测试的最大电流不同，所述电源通道开关控制所述电源输出模块的各路电源输出通道输出到硬盘的通路的导通和关断。In order to control the voltage and current sampling accuracy, specifically, the power output module also sets different current collection gears and is connected to the sampling module 300 through a power channel switch; the power channel switch is used to control the gear of the current output by each power output channel of the power output module, and different gears can test different maximum currents. The power channel switch controls the conduction and disconnection of the path of each power output channel of the power output module output to the hard disk.
例如为M.2接口固态硬盘提供3.3V±10％电压，为SATA接口固态硬盘提供5V±10％电压，为U.2接口固态硬盘提供12V±10％或者3.3V±10％电压。For example, a 3.3V±10% voltage is provided for an M.2 interface solid-state drive, a 5V±10% voltage is provided for a SATA interface solid-state drive, and a 12V±10% or 3.3V±10% voltage is provided for a U.2 interface solid-state drive.
需要说明的是，本实施例所展现的一个电源输出模块有两个电源输出通道，但是因为电源输出模块内部存有寄存器，所以可以控制两个通道中产生不同的输出电压，实现多路电压的区别控制，使得测试过程更加灵活。It should be noted that the power output module shown in this embodiment has two power output channels, but because the power output module has registers inside, it is possible to control the two channels to generate different output voltages, thereby achieving differentiated control of multiple voltages, making the test process more flexible.
其中，电源输出接口400和电源输出模块200具有相同数量的电源输出通道，每个电源输出通道用于和外部被测设备连接。图1中的电源输出模块设置有两个电源输入通道，因此其通过两根连接线和采样模块300连接，则电源输出接口400也有两个对外的电源输出通道供外部的被测设备连接。The power output interface 400 and the power output module 200 have the same number of power output channels, each of which is used to connect to an external device under test. The power output module in FIG1 is provided with two power input channels, so it is connected to the sampling module 300 via two connecting wires, and the power output interface 400 also has two external power output channels for connecting to an external device under test.
可以理解，一个连接通道对应测试用的一个被测设备，则采样模块300会分别采集每个连接通路上，本实施例中，所述采样模块连接于所述电源输出模块和所述电源输出接口之间，以进行电路数据的采样。It can be understood that one connection channel corresponds to one device under test for testing, and the sampling module 300 will collect data on each connection path respectively. In this embodiment, the sampling module is connected between the power output module and the power output interface to sample circuit data.
其中，采样模块300通过并联的方式，连接在电源输出模块和电源输出接口之间的输出通道上，以探测该输出通道上的参数。如图2所示，为采样模块300内部结构图，该采样模块300包括电流采样模块310和同步采样模数转换器320。The sampling module 300 is connected in parallel to the output channel between the power output module and the power output interface to detect the parameters on the output channel. As shown in FIG2 , it is an internal structure diagram of the sampling module 300 , and the sampling module 300 includes a current sampling module 310 and a synchronous sampling analog-to-digital converter 320 .
其中，该电流采样模块310中包括多个放大器311，所述放大器311用于放大所述电源输出模块的各个电源输出通道的电流。因为电路是一个回路，所以采样模块可以直接采集这些通路上的电流作为测试时的电流。The current sampling module 310 includes a plurality of amplifiers 311, and the amplifiers 311 are used to amplify the current of each power output channel of the power output module. Because the circuit is a loop, the sampling module can directly collect the current on these paths as the current during the test.
所述同步采样模数转换器用于接收所述电流采样模块310放大后的各个电源输出通道的电流，并进行模数转换，将得到的电流或者电压转换成数字信息，完成数据采集。The synchronous sampling analog-to-digital converter is used to receive the current of each power output channel amplified by the current sampling module 310, and perform analog-to-digital conversion to convert the obtained current or voltage into digital information to complete data collection.
其中，所述电流采样模块310和所述电源输出模块之间的电路上设置有检流电阻，所述放大器通过开尔文方式连接所述检流电阻。所述电源输出模块和所述同步采样模数转换器之间通过电压检测线路连接，所述电压检测线路上通过开尔文接法连接到待测单元，用于检测所述被测设备的电压信号。A current sensing resistor is provided on the circuit between the current sampling module 310 and the power output module, and the amplifier is connected to the current sensing resistor via a Kelvin connection. The power output module and the synchronous sampling analog-to-digital converter are connected via a voltage detection circuit, and the voltage detection circuit is connected to the unit under test via a Kelvin connection to detect the voltage signal of the device under test.
其中，上述的电源输出模块可以有多个，且随着电源输出模块的增加，采样模块也需要相应增加，然后在设置足够数量的电源输出接口就可以实现电源板的扩充，使得一个电源板可以同时为更多的硬盘进行供电，这样在测试时，可以同时进行更多的硬盘的同步测试。Among them, there can be multiple power output modules mentioned above, and as the power output modules increase, the sampling modules also need to be increased accordingly. Then, by setting a sufficient number of power output interfaces, the power board can be expanded, so that one power board can supply power to more hard disks at the same time. In this way, more hard disks can be tested simultaneously during testing.
为了更好的理解本实施例的电源板，如图3所示，为本实施例多通道输出与监控的程控电源板的电路示意图。In order to better understand the power board of this embodiment, as shown in FIG3 , it is a circuit diagram of the programmable power board with multi-channel output and monitoring of this embodiment.
图3中的电源板中设置有两个电源输出模块，该两个电源输出模块之间并联，同时为了检测两个电源输出模块提供的四条电源输出通路，因此设置了两个电流采样模块310。The power board in FIG. 3 is provided with two power output modules, which are connected in parallel. In order to detect four power output paths provided by the two power output modules, two current sampling modules 310 are provided.
可以看到，电流采样模块310和电源输出模块之间的电路中设置有电源通道开关，该电源通道开关可以控制输出的实际电压输出通路的开关。同时电流采样模块310和电源输出模块之间的线路中，设置有多个检测电阻R1，用于检测工作时的工作电流，如图3所示，放大器的两个引脚分别跨设于检测电阻的两端，这样可以采集到电阻带来的压降，然后放大，发送给模数转换器。It can be seen that a power channel switch is provided in the circuit between the current sampling module 310 and the power output module, and the power channel switch can control the switch of the actual voltage output path. At the same time, a plurality of detection resistors R1 are provided in the circuit between the current sampling module 310 and the power output module, which are used to detect the working current during operation. As shown in FIG3 , the two pins of the amplifier are respectively arranged across the two ends of the detection resistor, so that the voltage drop caused by the resistor can be collected, and then amplified and sent to the analog-to-digital converter.
当电源通道打开时，电流通过检流电阻流入负载，检流电阻两端会因为该电流产生一个电压降，将电压降放大并除以电阻值即可监控电流，同时，数模转换器可以采样负载电压，将两者一起传输到处理器中进行运算转换相乘即可得到实时功率。When the power channel is turned on, current flows into the load through the current-sense resistor. A voltage drop is generated across the current-sense resistor due to the current. The current can be monitored by amplifying the voltage drop and dividing it by the resistance value. At the same time, the digital-to-analog converter can sample the load voltage and transmit both to the processor for calculation, conversion and multiplication to obtain real-time power.
其中电流检测放大器的极低偏移电压Vos保证了在小信号输入时放大后的信号偏差尽可能小，极大的提高了采集精度，同时通过开尔文接线法检测负载端的电压信号，避免了由于电源通道中的电流而造成的线路损耗降低检测精度，两者通过ADC输出通道同步输出到输出接口中通过连接外部处理器来监控电压与电流，并以此计算实时功率，达到实时监控的目的。The extremely low offset voltage Vos of the current detection amplifier ensures that the deviation of the amplified signal is as small as possible when a small signal is input, which greatly improves the acquisition accuracy. At the same time, the voltage signal at the load end is detected by the Kelvin wiring method, which avoids the line loss caused by the current in the power supply channel and reduces the detection accuracy. The two are synchronously output to the output interface through the ADC output channel. The voltage and current are monitored by connecting to an external processor, and the real-time power is calculated based on this to achieve the purpose of real-time monitoring.
从图3的电路结构可知，其可以支持同时进行四个硬盘的测试，若是需要进行扩展，则可以通过添加新的电源输出模块、电流采样模块310、采样模数转换器来进行扩充，并且将新添加的和原本的模块器件进行如图3所示的并联即可完成扩展。As can be seen from the circuit structure of Figure 3, it can support the testing of four hard disks at the same time. If expansion is required, it can be expanded by adding a new power output module, a current sampling module 310, and a sampling analog-to-digital converter, and the newly added and original module devices can be connected in parallel as shown in Figure 3 to complete the expansion.
在一个可选的实施例中，采样模块和电源输入接口还通过控制接口连接，采样模块通过所述控制接口接收来自上位机的控制命令，如图3所示，该控制接口可以是电源输入接口下方标记的ADC控制接口。In an optional embodiment, the sampling module and the power input interface are also connected through a control interface, and the sampling module receives control commands from the host computer through the control interface. As shown in Figure 3, the control interface can be the ADC control interface marked below the power input interface.
因此，本实施例中的电源板结构进行硬盘测试时，可以同时进行两个硬盘的测试，测试时，本实施例的电源板插在底板上，由底板为电源板供电，同时电流从电源输入端流入电源输出端，进入被测试的硬盘中，底板通过I2C总线控制电源输出模块的输出电压，以进行测试过程的控制，同时因为通电后，硬盘和与之连接的电源输出通道形成回路，所以采样模块310可以直接采集到电流值，并通过内置的放大器放大电流值，而且电压检测线路上通过开尔文接线法连接，用于检测所述被测设备的电压信号。由此本实施例的电源板实现多个硬盘并行测试的同时，又可以实现在测试时对电流电压的采样，实现实时监控的效果。Therefore, when the power board structure in this embodiment performs hard disk testing, two hard disks can be tested at the same time. During the test, the power board of this embodiment is inserted into the base plate, and the base plate supplies power to the power board. At the same time, the current flows from the power input end to the power output end and enters the hard disk being tested. The base plate controls the output voltage of the power output module through the I2C bus to control the test process. At the same time, because the hard disk and the power output channel connected to it form a loop after power is turned on, the sampling module 310 can directly collect the current value and amplify the current value through the built-in amplifier, and the voltage detection circuit is connected through the Kelvin wiring method to detect the voltage signal of the device under test. Therefore, the power board of this embodiment can realize the parallel testing of multiple hard disks, and can also realize the sampling of current and voltage during the test, so as to achieve the effect of real-time monitoring.
