DETAILED DESCRIPTION
[0025] In order to make the purpose, advantages and features of the utility model clearer, the following is a further detailed description of a signal processing computer proposed by the utility model in conjunction with the accompanying drawings and specific embodiments. According to the following specific implementation methods, the advantages and features of the utility model will be clearer.
[0026] See also Figure 1-Figure 3 The utility model is a signal processing computer comprising a casing 1, a display 2 and a keyboard 3 installed on the casing 1, a processing module 4, a power module 5 and a heat sink 6 installed in the casing 1, and a waveform acquisition module 7 and a heating device; the display 2, the keyboard 3, the processing module 4 and the heat sink 6 are all electrically connected to the power module 5; the display 2, the keyboard 3 and the heat sink 6 are all electrically connected to the processing module 4; wherein the heat sink 6 is a fan in this embodiment, which can play a role in heat dissipation and temperature reduction by accelerating the air flow speed.
[0027] The power module 5 is connected to the power supply by connecting to an external power adapter, thereby realizing power supply for the whole machine, or using the electric energy stored in itself to power the whole machine; the power adapter includes a protection circuit, an EMI (filtering) circuit, and a power conversion unit; wherein the power conversion unit is mainly used to convert the external 220VAC alternating current into 28VDC direct current. The power module 5 inside the computer converts the external 28VDC direct current into 12VDC, 5VDC, and 3.3VDC voltages, thereby supplying power to each power unit.
[0028] The processing module 4 mainly completes the control of the whole machine and provides external expansion interfaces such as USB and network port. The processing module 4 includes a processor, memory, solid state, DP-LVDS conversion circuit and related expansion interface circuits. The DP-LVDS conversion circuit converts the DP video interface signal output by the processor into an LVDS video interface signal so as to connect the display 2 of the LVDS video interface, thereby outputting specific display information; the USB hub circuit expands one USB2.0 interface of the processor into four USB2.0 interfaces, two of which are used for USB3.1 interfaces, and the other two USB2.0 interfaces are used as independent USB2.0 interfaces for reserved expansion; 2 PCIE3.0x4 interfaces are used to connect the waveform acquisition module 7, and 2*USB2.0, 2*USB3.1 (including USB2.0), 1*GBE, 1*COM, 1*DP / HDMI / VGA and other interfaces are reserved to the outside of the device. Specifically, the processor used is CD-3644, which supports X86 and X64 working modes, ensuring that the WIN7 operating system can run; the memory uses a memory module composed of DDR4 particles; the solid state uses a solid state module composed of FLASH particles.
[0029] The function of the waveform acquisition module 7 is similar to that of an oscilloscope, and is mainly used to realize the acquisition of waveform signals and forward the acquired waveform signals to the processing module 4. The waveform acquisition module 7 is installed in the housing 1 and is electrically connected to the power module 5 and the processing module 4 respectively. Specifically, the waveform acquisition module 7 adopts the existing technology, and the general waveform acquisition module 7 is composed of an analog front end, an ADC unit, an FPGA unit and a calibration circuit. Among them, the analog front end adjusts the external signal voltage to within the acceptable range of the ADC unit, and filters the interference in the external signal; the ADC unit samples the filtered external signal, and transmits the sampling result to the FPGA through the JESD204B interface bus, and the FPGA saves the sampled data to the background storage device, and when the processing module 4 needs it, it is batch-transmitted to the processing module 4 through the PCIE interface. The calibration circuit is mainly used to generate the test case waveform, which is buffered and amplified and then output to the ADC unit. The ADC unit collects the test case waveform and inputs the collected data to the FPGA. The FPGA then compares the test case waveform with the external signal to detect whether the external signal collected by the ADC unit meets the preset characteristic requirements. If it does, it can be forwarded to the processing module 4; if it does not, it is sampled again until it meets the requirements. Specifically, the ADC unit selects the GAD10SL5GMPB type 4 / 2 / 1 channel 10-bit 1.25 / 2.5 / 5.0GSPS sampling rate A / D converter to achieve high-speed sampling of external signals, and the FPGA selects the JFM7K325T.
[0030] The display 2 mainly displays the corresponding signal waveform according to the signal waveform data; specifically, the display screen can be a liquid crystal screen with only a display function, or a touch screen with a display and human-computer interaction function. Specifically, the display 2 includes a display screen 21, a front shell 22 and a rear shell 23 respectively arranged on the front and back of the display screen 21.
[0031] In order to enable the computer to be used normally in a low temperature environment, a heating device is installed on the display 2; specifically, the heating device is a heating film 8; Figure 2 The heating film 8 is attached to the back of the display screen 21 and is electrically connected to the power module 5 through a switch; it can be turned on or off by the switch, which can be either a manual switch or an automatic switch; thus, when the external temperature is lower than the preset threshold, the display 2 is heated, so that the machine can maintain normal operation even in a low temperature environment of -40°C.
[0032] In a specific embodiment of the utility model, when the switch adopts an automatic switch, a temperature sensor can be further provided, and the switch can be electrically connected to the processing module. The external temperature is detected by the temperature sensor. When the external temperature is detected to be lower than a preset threshold, a signal is sent to the processing module. The processing module automatically controls the switch to open, thereby heating the display screen 21 through the heating film 8.

Specifically, the number of blocks is three; two of the blocks are side blocks 13, and the other is a middle block 14; the waveform acquisition module 7 and the processing module 4 are respectively installed between the middle block 14 and the corresponding side blocks 13 on both sides thereof.
