[0035] With the continuous development and advancement of communication technology, signal acquisition and playback equipment has become more important and widely used in various communication scenarios such as satellite communication and radar communication, and the requirements for the sampling rate and signal bandwidth of such equipment have also increased accordingly.

[0036] Generally speaking, in communication application scenarios, signal acquisition and playback equipment mainly collects and records signals within the signal coverage range of certain specific application scenarios, and can also play back the collected signals as needed. Due to the diversity of application scenarios and the large frequency variation range of the signals to be collected, current signal acquisition and playback equipment is difficult to meet signal acquisition needs. In addition, considering the complexity of the environment in which the application scenarios are located, signal acquisition and playback equipment needs to adapt to various complex environments and also requires a stable and safe power supply, which also puts higher requirements on signal acquisition and playback equipment.

[0037] In view of this, an embodiment of the present application provides a signal acquisition and playback device, which, through a specific hardware architecture and corresponding functional modules, can realize the acquisition and playback of various types of signals, and supports the storage of signals and signal processing results, has a stable power supply, and can meet the communication application requirements of high sampling rate and large bandwidth in complex environments.

[0038] According to the signal acquisition and playback device of the embodiment of the present application, the signal acquisition and playback device at least includes a shell, a signal processing module, a control module, a storage module, a display module, a power module and an interface module. The signal processing module is respectively connected to the control module, the storage module, the display module, the power module and the interface module, and the storage module is also connected to the display module, the interface module and the power module; wherein the shell can carry and support each module of the signal acquisition and playback device, which is equivalent to providing a protection function; the signal processing module provides the core functions of the signal acquisition and playback device, and can be used to acquire, process and play back preset signals; the control module is equivalent to a human-computer interaction function module, and the user can use the control module to control the signal acquisition and playback The device sends control instructions, and the control module can point to the corresponding signal control operation based on the control instructions; the storage module provides a storage function for the signal acquisition and playback device, which can be used to store the acquired signals and the result data generated by signal processing; the display module can display the acquired signals, signal processing results, device parameters and other data, so that the data can be displayed in a more intuitive and convenient form; the power module can provide power for the signal acquisition and playback device, thereby ensuring the normal operation of the signal acquisition and playback device; the interface module provides an interface between the signal acquisition and playback device and the external device, so that the signal acquisition and playback device can be applied to more scenarios and cooperate with more external devices to perform corresponding signal processing.

[0039] Figure 1 A block diagram of a signal acquisition and playback device provided in an embodiment of the present application. Figure 1 The signal acquisition and playback device 100 may at least include: a housing 110 , a signal processing module 120 , a control module 130 , a storage module 140 , a display module 150 , a power module 160 and an interface module 170 .

[0040] The signal processing module 120 is respectively connected to the control module 130 , the storage module 140 , the display module 150 , the power module 160 and the interface module 170 , and the storage module 140 is also connected to the display module 150 , the power module 160 and the interface module 170 .

[0041] In some optional implementations, the shell 110 can be used to provide a carrying shell for the signal acquisition and playback device 100; the signal processing module 120 can be used to acquire, process and playback preset signals; the control module 130 can be used to perform signal control operations according to received control instructions; the storage module 140 can be used to store preset signals and signal processing results of preset signals; the display module 150 can be used to display at least one of the preset signals, signal processing results and device parameters; the power supply module 160 can be used to provide power supply for the signal acquisition and playback device 100; the interface module 170 can be used to connect the signal acquisition and playback device 100 to the interface of an external device.

[0042] In some optional implementations, the control module 130 can be used to adjust acquisition parameters such as acquisition frequency and acquisition bandwidth range during signal acquisition; accordingly, the signal processing module 120 is connected to the control module 130, so the signal processing module 120 can perform signal acquisition operations based on the adjusted acquisition parameters such as acquisition frequency and acquisition bandwidth range. In other words, the signal acquisition and playback device of the embodiment of the present application can realize signal acquisition with variable frequency points, and the acquisition bandwidth is adjustable and variable, so that it can be applied to a wider range of communication application scenarios.

[0043] Similarly, the control module 130 can also be used to configure and adjust playback parameters during signal playback; accordingly, the signal processing module 120 is connected to the control module 130, so that the signal processing module 120 can perform signal playback operations based on the set playback parameters.

[0044] In some optional implementations, the power module 160 supports multiple power supply modes, which may include multiple power supply links, and one power supply mode corresponds to one or more power supply links. Among them, the power supply mode may include an internal battery power supply mode and an external power supply power supply mode, etc., which is not limited in the embodiments of the present application. When supplying power, some of the power supply links can be used to provide power supply for the signal acquisition and playback device, and different power supply modes or different power supply links can be switched for different scenarios.

[0045] That is to say, the power supply module 160 can realize the power supply to the signal acquisition and playback device through a variety of power supply modes. Therefore, even if one of the power supply modes fails, the remaining power supply modes can still be used to realize power supply. In addition, if a certain power supply mode corresponds to multiple power supply links, even if some of the power supply links corresponding to the power supply mode fail, as long as there are remaining non-faulty power supply links, the signal acquisition and playback device can still be powered based on the power supply mode. By setting multiple power supply modes and redundant power supply links, the power supply flexibility and power supply stability can be further improved, so that the signal acquisition and playback device can operate more stably, safely and effectively.

[0046] In some optional implementations, the storage module 140 may include a storage hard disk, a storage card (such as a secure digital card (SD card)), a disk, etc., for storing data such as collected signals and some signal processing results.

[0047] In summary, in the embodiment of the present application, the signal acquisition and playback device at least includes a shell, a signal processing module, a control module, a storage module, a display module, a power module and an interface module. The signal processing module is connected to the control module, the storage module, the display module, the power module and the interface module respectively, and the storage module is also connected to the display module, the interface module and the power module; wherein the shell can carry and support the various modules of the signal acquisition and playback device, which is equivalent to providing a protection function; the signal processing module provides the core functions of the signal acquisition and playback device, and can be used to acquire, process and play back preset signals; the control module is equivalent to a human-computer interaction function module, and the user can use the control module to control the signal acquisition and playback device Send control instructions, and the control module can point to the corresponding signal control operation based on the control instructions; the storage module provides a storage function for the signal acquisition and playback device, which can be used to store the acquired signals and the result data generated by signal processing; the display module can display the acquired signals, signal processing results, equipment parameters and other data, so that the data can be displayed in a more intuitive and convenient form; the power module can provide power for the signal acquisition and playback device, thereby ensuring the normal operation of the signal acquisition and playback device; the interface module provides an interface between the signal acquisition and playback device and the external device, so that the signal acquisition and playback device can be applied to more scenarios and cooperate with more external devices to perform corresponding signal processing.

[0048] The signal acquisition and playback device of the embodiment of the present application is described in detail below.

[0049] In some optional implementations, the housing is used to carry and place various modules of the signal acquisition and playback device to protect these modules and alleviate the impact of external forces on these modules. The housing can be made of a variety of materials, and the shape and size of the housing can be set according to actual needs, experience, simulation data, etc., and the embodiments of the present application are not limited to this.

[0050] Exemplarily, the shell may include four side panels, a top panel and a bottom panel. By assembling the side panels, the top panel and the bottom panel, a rectangular cavity structure may be formed to place functional modules such as a signal processing module and a control module in the cavity.

[0051] For example, the housing may include an upper-opening cavity structure and a top plate, and a closed cavity structure is obtained by assembling the top plate onto the upper-opening cavity structure, so that functional modules such as a signal processing module and a control module can be placed in the cavity. The upper-opening cavity structure and the top plate can be obtained by production methods such as computerized numerical control (CNC) processing and machining.

[0052] In some optional implementations, the control module includes a membrane keypad and a connector, the membrane keypad includes a plurality of function keys, and the connector is used to connect the membrane keypad and the signal processing module. The membrane keypad is a polyester film (PET film) with contacts, which is used as a switch on circuit boards such as printed circuit boards (PCB) and flexible printed circuits (FPC), and acts as a touch switch between the device user and the device, transmitting various operation instructions (such as control instructions) issued by the device user. Compared with traditional silicone keys, membrane keypads have a better feel and longer life.

[0053] Exemplarily, the control module includes a membrane keypad and a flat cable (i.e., a connector). The membrane keypad can be attached to the housing by adhesive backing, and the membrane keypad is composed of a panel, a top adhesive, an upper circuit, an isolation layer, a lower circuit, and a bottom adhesive in order from the outside to the inside. The panel is mainly used to set logos and buttons, and the upper circuit and the lower circuit are used to turn on or off the circuit according to the state of the button; the flat cable is mainly used to connect the membrane keypad and the signal processing module, and is used to transmit corresponding signals between the two, so as to transmit the operation instructions given by the user through the membrane keypad to the signal processing module, so that the signal processing module can perform corresponding operations (for example, frequency adjustment, signal acquisition, signal playback, etc.) according to the operation instructions.

[0054] Furthermore, for example, main functional keys such as frequency adjustment keys, operation type keys, power keys, storage operation keys, and auxiliary keys such as confirmation keys and return keys can be set on the membrane keypad; for a certain key, when the key is not pressed, the switch is in a normal state, and its upper and lower contacts are in a disconnected state, and the isolation layer isolates the upper and lower circuits; when the key is pressed, the contacts of the upper circuit deform downward, overlap with the lower circuit and make the circuit conductive, and the conductive circuit sends a corresponding signal to an external connection instrument (such as a signal processing module), thereby realizing its corresponding function; when the finger is released, the contacts of the upper circuit bounce back, the circuit is disconnected, and the loop triggers a signal.

[0055] It should be noted that the above keys provided on the membrane keypad are merely examples, and the embodiments of the present application do not limit this.

[0056] In some optional implementations, the display module may include a display screen and a supporting structure, wherein the supporting structure is used to fix the display screen inside the shell; wherein the display screen can be used to display some information (such as collected signals, signal processing results, etc.).

[0057] Exemplarily, the display screen may be a liquid crystal display screen, an organic light-emitting display screen (ie, an organic light-emitting diode (OLED) screen), a full-color screen, etc., and the embodiments of the present application are not limited thereto.

[0058] Exemplarily, the display screen can display preset signals collected in real time or replay preset signals that have been collected and stored, and can also display signal processing results for preset signals (such as upsampling results, downsampling results, filtering results, etc.). In addition, some device parameters (such as battery power, etc.) can also be displayed through the display screen. Among them, the preset signal can include various communication signals, such as Global Navigation Satellite System (GNSS) signals, etc., and the embodiments of the present application are not limited to this.

[0059] In some optional implementations, the support structure may include a first mounting component and a second mounting component, the first mounting component is used to assemble the display screen to the support structure, and the second mounting component is used to fix the support structure assembled with the display screen in the housing.

[0060] Exemplarily, the first installation component and the second installation component may include screws, detachable buckles, etc., which are not limited in the embodiments of the present application.

[0061] That is to say, the first installation component is mainly used to assemble the display screen and the support structure together, and the second installation component is used to fix the assembled display screen and the support structure as a whole to the inside of the shell. Correspondingly, when assembling and installing, the display screen can be first fixed to the support structure based on the first installation component, and then the support structure with the display screen fixed can be installed on the shell. Through this setting method, it is convenient to complete the assembly of the display module in a smaller space, alleviating the impact of the shell size limitation on the installation of the display module.

[0062] Figure 2 A schematic diagram of a display module provided in an embodiment of the present application. Figure 2 The display module 150 includes a display screen 1510 and a support structure 1520 , and the support structure 1520 includes a first mounting component 1521 and a second mounting component 1522 ; wherein the second mounting component 1522 is located at the upper position of the entire support structure 1520 .

[0063] like Figure 2 As shown, the display screen 1510 can be installed on the support structure 1520 through the first installation component 1521, so that the two form an integral structure. Further, the aforementioned integral structure can be installed inside the shell through the second installation component 1522. Based on this installation method, even if the lower side of the display module 150 is close to the bottom of the shell and the operable space is small, the installation operation with the shell is less affected by the above-mentioned operating space because the second installation component 1522 is relatively high. Therefore, the second installation component can still be used to more conveniently install the display module 150 in the shell, without increasing the difficulty of installation and assembly due to space limitation, and without increasing the shell size to avoid space limitation, resulting in increased equipment cost.

[0064] Furthermore, the normal operation of the signal acquisition and playback device requires the power supply provided by the power module. In some optional implementations, the power module includes a first power submodule and a second power submodule; wherein the first power submodule includes at least one battery unit and provides power to the signal acquisition and playback device based on the battery unit; the second power submodule uses an external power supply to provide power to the signal acquisition and playback device, and charges the battery unit in the first power submodule.

[0065] From this, it can be seen that the first power supply submodule supports one power supply mode, and the second power supply submodule supports another power supply mode, that is, the signal acquisition and playback device can adopt two power supply modes. The first power supply mode is powered by a battery (corresponding to the first power supply submodule), and the second power supply mode is powered by a power supply outside the device (corresponding to the second power supply submodule).

[0066] In some optional implementations, the first power submodule includes a plurality of battery cells, which can be connected in parallel to form a parallel power supply structure. Moreover, any one of the battery cells in the parallel power supply structure can meet the power supply of the signal acquisition and playback device. Therefore, through this parallel structure, when a certain battery cell cannot provide power supply (such as insufficient power or failure, etc.), any remaining battery cell can provide power supply in time. Based on this power supply method, the operating time of the device can be improved, thereby ensuring that the signal acquisition and playback device can work continuously and stably.

[0067] In some optional implementations, in order to timely detect the working status of the power module and ensure the stable operation of the power module, some sensors can also be set to obtain corresponding sensor data, and judge whether the working status of the power module is normal through the sensor data, so as to perform corresponding processing in time to make the power module operate safely and stably.

[0068] In some optional implementations, the power module further includes at least one sensor, which is used to detect operating parameters of the battery unit, wherein the operating parameters include some parameters generated by the battery unit during operation or some parameters of the environment in which the battery unit is located.

[0069] Further, after detecting the working parameters of the battery unit, a reminder message can be generated based on the working parameters and / or the working mode of the power module can be controlled. For example, after detecting the working parameters, the sensor can generate some control instructions (such as interrupt charging control instructions, switching power supply mode control instructions, switching power supply link control instructions, etc.) according to the working parameters, and send these control instructions to the signal processing module, the control module or the display module, etc., and these modules generate and send operation instructions (such as interrupt charging execution instructions, switching power supply mode execution instructions, switching power supply link execution instructions, etc.) to the power module based on the received control instructions, so as to control the corresponding working mode of the power module through these operation instructions. In addition, the sensor can also generate some reminder instructions (such as temperature too high reminder message, temperature too low reminder message, etc.) according to the working parameters, and send these reminder instructions to the signal processing module, the control module or the display module, etc., so as to be able to timely adjust the working mode of the relevant functional modules or send warning signals to the user, so as to ensure that the signal acquisition and playback device can operate stably and safely.

[0070] Exemplarily, the power module includes at least one temperature sensor, which is arranged near the first power submodule to detect the temperature corresponding to the battery cell in the first power submodule, which can be the operating temperature of the battery cell (i.e., the temperature of the battery cell itself) or the temperature of the environment in which the battery cell is located. If the temperature is detected to be lower than the first threshold value (such as -20°), considering the impact of low temperature on battery performance, the battery cell is no longer used to power the signal acquisition and playback device, but the second power submodule is used to power it; if the temperature is detected to be higher than the second threshold value (such as 40°), considering that charging the battery in a high temperature environment may bring potential safety hazards, therefore, if the battery cell is in a charging state, the battery cell is stopped from being charged to avoid dangers caused by excessive temperature.

[0071] Furthermore, in response to the detection that the temperature exceeds the first threshold or the second threshold, a corresponding reminder message (such as a high temperature reminder message, etc.) can be generated and displayed to the user through a display module, etc., so that the user can intervene in time to reduce the possibility of failure and danger.

[0072] Exemplarily, the power module includes at least one humidity sensor, which detects the humidity of the environment in which the power module is located to avoid dangers caused by excessive humidity (such as short circuit risks). If the detected humidity exceeds a preset threshold range, a preset operation (such as automatic power off) can be performed, and a corresponding reminder message can also be issued.

[0073] In some optional implementations, in order to protect the battery module, the battery module can be fixed in the housing by some fixing structures. For example, the fixing structure may include a protective frame and screws for connecting the protective frame to the housing, and the battery module is located in the protective frame. As for the protective frame, it can be made of various materials (such as polyethylene, metal, etc.), can be obtained by assembling multiple accessories, or can directly generate an integrated frame structure, which is not limited in the embodiments of the present application.

[0074] In summary, the battery module can provide a stable and safe power supply for the signal acquisition and playback equipment, and can also detect its working status through some sensors, so as to intervene in some specific situations in time and further improve the stability and safety of power supply.

[0075] In some optional implementations, the signal acquisition and playback device may further include: a heat dissipation module, the heat dissipation module includes an air cooling sub-module and / or a liquid cooling sub-module; wherein the air cooling sub-module is a sub-module that performs heat dissipation based on air cooling, and the liquid cooling sub-module is a sub-module that performs heat dissipation based on liquid cooling.

[0076] Air cooling mainly uses air as a medium to cool objects that need to be cooled (such as signal acquisition and playback equipment). It can dissipate heat by increasing the surface area of ​​the object to be cooled, or by speeding up the rate at which air flows through the object per unit time. It can also combine these two methods to dissipate heat together. Liquid cooling mainly uses flowing liquid to transfer the heat generated by the object to be cooled to the outside of the object to ensure that it works within a safe temperature range.

[0077] It can be seen from this that the heat dissipation of the signal acquisition and playback device can be processed by air cooling and / or liquid cooling, thereby keeping the signal acquisition and playback device in a good working condition and ensuring that it can perform the corresponding signal processing normally.

[0078] In some optional implementations, the air cooling submodule includes a partition structure arranged in the shell, the partition structure is used to isolate the signal processing module from the top plate of the shell, and the partition structure includes at least one fan and an air duct; a first vent and a second vent are provided on the shell; wherein the fan is used to draw air from outside the shell into the air duct through the first vent, use the inhaled air to absorb heat generated by the signal acquisition and playback device, and discharge the air after absorbing the heat out of the shell from the second vent.

[0079] Exemplarily, the shell is divided into two parts, an upper part and an lower part, by a partition structure, a first vent is set on the upper shell, a second vent is set on the lower shell, and a corresponding fan and air duct are set on the partition structure. After the fan is turned on, cold air is sucked into the upper shell from the outside through the first vent, enters the air duct through the fan, and enters the lower shell through the air duct. After fully absorbing the heat generated by the signal processing module in the lower shell, it flows out of the shell from the second vent, thereby realizing effective heat dissipation of the signal acquisition and playback equipment.

[0080] Figure 3 This is a schematic diagram of a heat dissipation module of a signal acquisition and playback device provided in Example 1 of the present application. Figure 3 The signal processing module 120 is arranged on the bottom plate of the housing 110, the first vent 1131 and the second vent 1161 are arranged on the side plate of the housing 110, and a partition structure 1810 is arranged inside the housing 110, and a fan 1820 and an air duct 1830 are arranged on the partition structure 1810. Cold air enters the upper part of the housing 110 through the first vent 1131, enters the lower part of the housing 110 through the fan 1820 and the air duct 1830, absorbs the heat of the signal processing module 120, and is discharged from the second vent 1161.

[0081] Figure 4This is a schematic diagram of a heat dissipation module of a signal acquisition and playback device provided in Embodiment 2 of the present application. Figure 4 A first vent 1131 and a second vent 1161 are respectively provided on the two side panels of the shell, a partition 1811 is provided on the PCB board (not shown in the figure), and a fan 1820 and an air duct 1830 with a special-shaped structure are provided on the partition 1811.

[0082] It should be noted that the above positions, quantities, etc. of the first vent, the second vent, the fan, and the air duct are all examples, and the embodiments of the present application do not limit this. In actual operation, the first vent is equivalent to an air inlet, the second vent is equivalent to an air outlet, and the positions of the above vents need to be reasonably set to ensure that the cold air from the outside can smoothly enter the interior of the shell, and the hot air after absorbing heat can be smoothly discharged. In addition, the direction of the air duct set up based on the top plate and other structures inside the shell should also be scientific and reasonable, so as to avoid the formation of air flow short circuits or dead corners as much as possible, so that the air can flow evenly over the surface of the heat dissipation unit in the shell to take away the heat. In addition, the size, power, etc. of the fan should also be reasonably configured to provide sufficient air volume to maintain air circulation.

[0083] Furthermore, in addition to the air-cooling submodule, a liquid-cooling submodule may be provided in the housing to dissipate heat by liquid cooling. For example, at least one liquid-cooling pipeline is provided on the signal processing module, and corresponding liquid inlets and outlets are provided on the housing. Coolant is injected into the liquid-cooling pipeline through the liquid inlet, and the coolant flows along the liquid-cooling pipeline, takes away the heat in the device, and then is discharged through the liquid outlet. The flow rate of the coolant may be set according to the heat dissipation requirements, and the embodiments of the present application are not limited thereto.

[0084] In some optional implementations, in order to expand the functions and application scenarios of the signal acquisition and playback device, an interface module can be set in the signal acquisition and playback device, and multiple interfaces can be configured based on the interface module to achieve interconnection between the signal acquisition and playback device and multiple external devices, so that the signal acquisition and playback device can process the data transmitted by the external device, or the external device can further process the signal collected by the signal acquisition and playback device or the signal processing results generated.

[0085] In some optional implementations, the interface module includes at least one of the following: a signal acquisition interface, a signal playback interface, a universal serial bus interface (such as a USB interface), a network cable interface, an expansion interface, an auxiliary interface, and a power interface.

[0086] Among them, the signal acquisition interface is mainly used for signal acquisition, for example, it can be used to collect various types of radar video signals and their corresponding flag signals; the signal playback interface is mainly used for signal playback, for example, it can be used to convert digital video signals into analog signals, and decode the corresponding flag signals therefrom, and the converted signals have sufficient driving capability to drive the radar display terminal, thereby realizing the restoration of radar signals; the universal serial bus interface can be used to connect some external devices to realize data interaction; the network cable interface is used to realize the connectivity of the network cable; the expansion interface can be used to connect some expansion peripherals to further improve the application scenarios; the auxiliary interface is an interface used to realize some auxiliary functions (such as clock functions, etc.); the power interface can be used to connect an external power supply.

[0087] In some optional implementations, the signal acquisition interface is connected to the first end of the first RF line, and the second end of the first RF line is connected to the signal processing module; the signal playback interface is connected to the first end of the second RF line, and the second end of the second RF line is connected to the signal processing module.

[0088] In some optional implementations, the first radio frequency line and the second radio frequency line may be prepared using radio frequency cables with high shielding performance, which can effectively resist external signal interference, thereby enabling accurate data transmission.

[0089] Exemplarily, the signal acquisition interface and the signal processing module can be connected via a first RF line, so that the signal collected by the signal acquisition interface is transmitted to the signal processing module based on the first RF line so that the signal processing module can perform corresponding processing on the signal; correspondingly, the signal playback interface and the signal processing module can be connected via a second video line, so that some processing results generated by the signal processing module (such as the collected signal or the signal processing result obtained by processing the collected signal, etc.) are sent to the signal playback interface based on the second RF line, so that signal playback and other processing can be performed through the signal playback interface.

[0090] It should be noted that since the first RF line and the second RF line can be bent and have various shapes, the positions of the signal acquisition interface and the signal playback interface can be reasonably arranged according to the shell size and the distribution positions of various functional modules in the device, without having to consider too much about the limitations caused by the need to connect the signal acquisition interface / signal playback interface and the signal processing module.

[0091] In some optional implementations, the number and type of expansion interfaces can be set according to signal processing requirements, experience, etc. For example, the expansion interfaces can include some serial ports, multi-purpose connection ports, etc., which are used to expand the types of devices that can be connected to the signal acquisition and playback device.

[0092] In some optional implementations, the auxiliary interface includes at least one of the following: a clock input interface, a clock output interface, an input event trigger interface, an output event trigger interface, and a pulse interface.

[0093] For example, the clock input interface is used to receive an external clock signal.

[0094] For example, the clock output interface is used to output the clock signal of the signal acquisition and playback device.

[0095] For example, the input event trigger interface is used to enable the signal acquisition and playback device to perform a preset operation in response to an input event.

[0096] For example, the output event triggering interface outputs a preset signal in response to an output event generated by the signal acquisition and playback device.

[0097] For example, the pulse interface is used to receive some external pulse signals (such as heartbeat signals, etc.).

[0098] It should be noted that the above interface types and numbers included in the interface module are merely examples and are not limited to this in the embodiments of the present application.

[0099] In some optional implementations, the signal processing module can be implemented based on a PCB board, in other words, the signal processing module can include a PCB board. Various electronic components can be arranged in the PCB board, and corresponding connection circuits can be laid out to achieve corresponding signal processing functions.

[0100] Exemplarily, a PCB board may include pads, vias, mounting holes, wires, components, connectors, fillings, electrical boundaries, etc., and the above structures are used to jointly implement preset signal processing functions (such as signal acquisition function, signal playback function, etc.).

[0101] In some optional implementations, the shell includes a bottom plate, a top plate, and four side plates, and the PCB board is disposed on the bottom plate.

[0102] Exemplarily, the shell forms a cubic cavity through a bottom plate, a top plate and four side plates, and fixes the PCB board on the bottom plate to protect the PCB board.

[0103] In some optional implementations, the base plate includes a first area covered with an oxide film (such as an aluminum oxide film) and a second area where the metal layer is exposed, and a thermal pad is provided between the second area and the PCB board. The thermal pad can improve the heat dissipation effect of the PCB board on the one hand, and on the other hand, the thermal pad can also be grounded, thereby effectively alleviating the electromagnetic compatibility (EMC) problem.

[0104] In some optional implementations, an oxide film may be coated on the surface of the bottom plate through an oxidation process, and the oxide film may act as a protective film. Further, on this basis, the preset area may be processed by etching or other processes to remove the oxide film in the preset area and expose the metal layer below, thereby forming the aforementioned second area, and the other areas of the bottom plate where the metal layer is not exposed are the aforementioned first areas.

[0105] In some optional implementations, the second area can be in a rectangular, square, circular, or other shape, and the installation position of the PCB on the bottom plate can also be determined based on the second area. In other words, the second area can be used as a reference position for installing the PCB, so that the PCB can be installed quickly and accurately, and the uniformity of the position of the PCB on the bottom plate can also be ensured.

[0106] Figure 5 A schematic diagram of a base plate provided in an embodiment of the present application. Figure 5 , a second area 1111 is provided on the bottom plate 1110, and other areas except the second area 1111 belong to the first area. The first area is coated with an oxide film, and the second area 1111 exposes the metal layer.

[0107] like Figure 5 As shown, the PCB board 1210 can be fixed on the base plate 1110, so that the components with more heat dissipation in the PCB board 1210 correspond to the corresponding positions of the second area 1111, and a thermal conductive gasket (not shown in the figure) is arranged between the second area 1111 and the PCB board 1210. The thermal conductive gasket further enhances the heat dissipation speed of the PCB board 1210 and improves the heat dissipation effect.

[0108] It should be noted that the size of the second area and its position on the bottom plate can be determined according to the heat dissipation and distribution position of the corresponding components in the PCB board. For example, the position and size corresponding to the components with more heat dissipation in the PCB board can be determined, and according to the corresponding area of ​​the PCB board on the bottom plate, the area corresponding to these components on the bottom plate can be determined, and then this part of the area is determined as the second area, and the oxide film coated on the surface of this part of the area is stripped off to expose the metal layer, or the exposed area is subjected to conductive treatment to obtain the metal layer, and some structures such as thermal conductive pads can be set between the metal layer and the PCB board, and structures such as shielding covers can also be set in the second area. Among them, the shielding cover is a tool for shielding electronic signals, which is used to shield the influence of external electromagnetic waves on the internal circuit and the electromagnetic waves generated inside from radiating outward, thereby further improving the stability of the circuit.

[0109] In some optional implementations, a first side panel among the four side panels of the shell is provided with multiple connectors corresponding to the interface module, the first side panel includes a third area covered with an oxide film and multiple fourth areas exposing the metal layer, and the fourth area is an area for fixing the connector on the first side panel.

[0110] In some optional implementations, a special-shaped structure can also be set on the side panel according to the shape of the interface. On the one hand, it can make the interface fit better with the side panel, and on the other hand, it can avoid exposure of the module inside the shell due to the shape of the interface, thereby minimizing the impact of external foreign matter such as dust entering the shell on device performance.

[0111] In some optional implementations, multiple connectors corresponding to the interface module are provided on the first side panel, and accordingly, the PCB board and the first side panel are fixed via a first mounting structure, and the first side panel on which the PCB board is fixed and the top panel are fixed via a second mounting structure.

[0112] Exemplarily, the first mounting structure and the second mounting structure may include screws, detachable buckles, etc., which is not limited in the embodiments of the present application.

[0113] Figure 6 This is a schematic diagram of a signal acquisition and playback device provided in Example 1 of the present application. Figure 6 The shell of the signal acquisition and playback device includes a bottom plate 1110 , a top plate 1120 , a first side plate 1130 , a second side plate 1140 , a third side plate 1150 and a fourth side plate 1160 , wherein the first side plate 1130 is provided with an interface module 170 .

[0114] like Figure 6 As shown, during the installation and assembly process, the bottom plate 1110, the second side plate 1140, the third side plate 1150 and the fourth side plate 1160 can be first installed into an open cavity structure (the bottom plate 1110 and the above three side plates can also be pre-generated integrated structures, in which case there is no need to perform the above assembly); in addition, the PCB board 1210 is fixed to the first side plate 1130 using a first installation structure (not shown in the figure), and in this process, the corresponding interface of the interface module 170 needs to be connected to the corresponding interface on the PCB board 1210 to ensure that the PCB board 1210 can receive or send accurate data to smoothly perform the corresponding signal processing function; then the first side plate 1130 fixed with the PCB board 1210 is assembled with the open cavity structure into an upper open cavity, and the top plate 1120 is assembled with the upper open cavity using a second installation structure (not shown in the figure) to form a closed cavity structure (i.e., a signal acquisition and playback device).

[0115] In contrast, if the bottom plate 1110 and the four side plates are assembled into a cavity structure with an upper opening, the PCB board and some interface modules need to be installed inside the cavity, and the operating space is relatively limited, especially when connecting the corresponding interface of the interface module 170 with the corresponding interface on the PCB board 1210. In this case, the shell size may need to be increased, which will increase the cost of the equipment. Figure 6 When assembled and installed in the manner shown, the limitation of the shell on the operable space can be removed, so there is no need to increase the size of the shell, thereby eliminating the need to increase the equipment cost.

[0116] Figure 7a , Figure 7b , Figure 7c and Figure 7d This is a schematic diagram of a signal acquisition and playback device provided in Embodiment 2 of the present application, showing the signal acquisition and playback device from different perspectives.

[0119] Among them, several interfaces are arranged on the first side panel 1130 of the shell, including a signal acquisition interface 1701, a signal playback interface 1702, a clock input interface 1703, a clock output interface 1704, an input event trigger interface 1705, an output event trigger interface 1706, a pulse interface 1707, an expansion interface 1708, a network interface 1709, a USB interface 1710 and a power interface 1711, and, for the expansion interface 1708, an interface special-shaped structure 1712 adapted to the outer contour of the expansion interface 1708 is arranged on the first side panel 1130, so that the expansion interface 1708 can be more closely installed and assembled on the first side panel 1130, while avoiding exposing the internal functional modules, so as to avoid dust and other foreign objects from entering the shell and affecting the functional modules therein; in addition, a first ventilation port 1131 and a buckle 1132 for fixing the first side panel 1130 and the top panel 1120 are also arranged on the first side panel 1130.

[0120] Reference Figure 7bA display screen 1510 is provided on the third side panel 1150 opposite to the first side panel 1130. The display screen 1510 is connected to the first end of the flat cable (not shown in the figure), and is connected to the signal processing module and other functional modules through the second end of the flat cable; in addition, a membrane keypad 1310 is also provided on the third side panel 1150. The membrane keypad 1310 is provided with a switch key, a frequency up key, a frequency down key, a confirmation key, a return key, a collection key, a playback key, a collection status indicator light, a playback status indicator light, a disk working status indicator light, and a switch status indicator light. Users can issue corresponding control instructions through the membrane keypad 1310 according to their needs, so that the corresponding functional module responds to the control instructions and performs matching signal processing operations.

[0121] Reference Figure 7c , from the first side panel as the main perspective, the side panel on the left side is the fourth side panel 1160, and the side panel on the right side is the second side panel 1140. In addition, the fourth side panel 1160 is provided with a second vent 1161, which cooperates with the first vent 1131 and the like to achieve heat dissipation of the signal acquisition and playback device.

[0122] Reference Figure 7d The bottom of the shell is composed of a base plate 1110, and the base plate 1110 is provided with base plate vents 1112 for heat dissipation and ventilation. The base plate vents 1112 can be used to further dissipate heat for the signal acquisition and playback device to improve the heat dissipation effect.
