[0041] In order to make the objectives, technical solutions and advantages of this application more clear, this application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0043] On vehicles, data from a variety of devices must be collected, and accurate collection of device status data, efficient computation, and linked output processing with video surveillance are crucial. This linked output allows for effective judgment of the proper functioning of various devices connected to the vehicle, thereby meeting the growing demand for intelligent and efficient vehicles.

[0044] Especially in the operation of large-scale road maintenance machinery and equipment, due to the characteristics of its working environment and the high load, it is more important to collect data from different connected devices and accurately collect equipment status data, perform efficient calculations and output linked to video monitoring.

[0045] In some embodiments, the monitoring device and display device of large-scale road maintenance machinery are from different manufacturers. To realize the linkage between the monitoring device and the display device, both parties need to provide an interface protocol for interface docking, and one or both parties need to carry out embedded software development to realize the interface docking. Figure 1 As shown, protocol exchange or switches are used to achieve interface docking. For embedded software, due to access restrictions, even if the software is available, it is impossible to directly switch the corresponding monitoring screen and alarm information.

[0046] For example, if a device like an axle temperature sensor generates an alarm and transmits it to a display device, the display device will need to manually launch software based on the alarm information and then switch to the corresponding camera or cameras to retrieve the image. The camera image cannot be directly displayed on the display device, so the video switching linkage function is not available.

[0047] Based on this, reference Figure 2 As shown, the embodiment of the present application provides a vehicle-mounted integrated data processing device, including:

[0048] At least one input interface, at least one output interface and a signal conversion module 2 , at least one input interface is connected to the monitoring device and is configured to collect detection information of the monitoring device 1 .

[0049] In an exemplary embodiment, the monitoring device 1 may be an axle temperature sensor, a switching switch, or the like.

[0050] In an exemplary embodiment, the number of input interfaces may be one or more, such as 2, 3, 4, 5, etc. For example, Figure 2 In the example, T1, T2, ..., T8 are determined by the number of devices that need to collect data or the type of data that needs to be collected. For example, if there are five devices that need to collect data, then five input interfaces are set. For example, if there are five devices that need to collect data, but three of the five devices collect the first type of data and two devices collect the second type of data, then two input interfaces can be set, with one input interface connected to each type of collection device.

[0051] Since the input interface is a physical interface, there is no need to consider the interface protocol compatibility of the detection device. As long as the connection is adaptable, the monitoring information collection of the detection device can be completed.

[0052] At least one output interface is connected to the display device 3 and the alarm device 4 respectively.

[0053] In an exemplary embodiment, the output interface can be one or more. Since the signal conversion module 2 converts different monitoring signals into digital signals, one output interface is sufficient to transmit the digital signals to the display device 3 and the alarm device 4 respectively. However, in order to avoid the inconvenience caused by the multiple digital signals causing crosstalk during the transmission process, or the inconvenience caused by the need to transmit a digital signal to the display device 3 and the alarm device 4 respectively, it can also be set to multiple, for example Figure 2 Among them, O1, O2...O8, etc. are not specifically limited here.

[0054] Similarly, since the output interface is a physical interface, there is no need to consider the interface protocol compatibility of the display device. As long as the connection is adaptable, signals can be transmitted to the display device and the alarm device.

[0055] The signal conversion module 2 is connected to at least one input interface and at least one output interface respectively, and is configured to convert the monitoring information into digital information and determine whether the digital information is alarm information;

[0056] If the digital signal is alarm information, the monitoring screen and alarm information of the monitoring device 1 are switched to the display device 3 through at least one output interface, and the alarm device 4 is controlled to alarm.

[0057] Because different monitoring devices have different signal types, for example, RS485 differential signals or switch signals, different signal types are directly displayed as alarm information on the display device 3. The display device 3 may not necessarily adapt to the signal type, resulting in the alarm information and monitoring screen being unable to be effectively displayed on the display device 3. Similarly, the alarm device 4 is also unable to effectively adapt to the alarm information type. By converting the monitoring information into a digital signal, it can be effectively displayed on the display device 3 and trigger the alarm device 4 to alarm.

[0058] It is understood that when a monitoring device 1 is provided, a camera or other device with monitoring functions is installed corresponding to the monitoring device 1 to collect corresponding monitoring images in real time. For example, if a hydraulic shaft of a large-scale road maintenance machine has an axle temperature sensor to collect monitoring information, a corresponding camera monitoring device is also installed. The camera and the corresponding axle temperature sensor are connected to at least one input interface to facilitate control of the camera's monitoring image display.

[0059] In some embodiments, the monitoring information includes a switch signal.

[0060] In some embodiments, reference Figure 2 、 Figure 3 As shown, a first acquisition module 21 is connected between the signal conversion module and at least one input interface; the first acquisition module 21 includes at least one first resistor and a latch module 212, at least one first resistor is respectively connected to at least one input interface and the latch module 212, the latch module 212 is connected to the signal conversion module 2, and the latch module 212 is configured to acquire a switch signal;

[0061] The signal conversion module 2 determines whether the switch signal is an alarm signal according to the level of the switch signal.

[0062] In an exemplary embodiment, a switch signal is a discontinuous signal having two states, 1 and 0, representing on and off states, respectively, and is used to indicate the opening and closing of a circuit, or the connection and disconnection of a contact, such as a button or contactor.

[0063] In an exemplary embodiment, the number of first resistors corresponds to the number of switch signals, such as Figure 3 As shown, when there are four switches (buttons, contactors) S1, S2, S3, and S4 inputting four switch signals, four first resistors R1, R2, R3, and R4 are set accordingly.

[0064] In this embodiment, at least one input interface is connected to an external switch (such as a push button switch or a contactor switch). The external switch is typically connected to a power supply (connected to the power supply via a pull-up resistor to provide a high level). The other end of the at least one input interface is connected to an input pin of the latch module 212 via a first resistor. When the external switch is closed, the input pin of the latch module 212 is pulled down to a low level (0); when the external switch is open, the input pin of the latch module 212 is at a high level (1). At this point, the latch module 212 completes the acquisition of the switch signal.

[0065] In an exemplary embodiment, the first resistor limits the current of the input switching signal to prevent the latch module or the signal conversion module from being damaged by excessive current of the switching signal.

[0066] After the latch module 212 completes the acquisition of the switch signal, it inputs the switch signal to the signal conversion module 2. The signal conversion module 2 determines whether the current external switch is open or closed based on the level of the switch signal, thereby determining whether the switch signal is an alarm signal. For example, if the current external switch should be closed and the level of the switch signal is high (1), then the current external switch is determined to be in the open state, and the switch signal is determined to be an alarm signal. If the level of the switch signal is low (0), then the current external switch is determined to be in the closed state, and the switch signal is determined not to be an alarm signal.

[0067] In an exemplary embodiment, the latch module 212 may be a latch chip, such as an ALE8155A chip.

[0068] It should be noted that, in this embodiment, the signal conversion module 2 also converts the switch signal into a digital signal.

[0069] In some embodiments, the monitoring information includes a differential signal.

[0070] In some embodiments, a second acquisition module 22 is connected between the signal conversion module 2 and at least one signal input interface; the second acquisition module includes a first connection line 221, a second connection line 222, a first matching resistor 223, and a first signal transceiver module 224. One end of the first connection line 221 and the second connection line 222 are connected to at least one input interface, and the other end is connected to the first signal transceiver module 224. The first signal transceiver module 224 is connected to the signal conversion module 2, and the first matching resistor 223 is connected between the first connection line 221 and the second connection line 222. The first signal transceiver module 224 is configured to collect differential signals.

[0071] The signal conversion module 2 determines whether the differential signal is an alarm signal according to the voltage difference of the differential signal.

[0072] In an exemplary embodiment, differential signaling is a signal transmission method that transmits signals in a differential form.

[0073] In an exemplary embodiment, there may be one or more first matching resistors 223 .

[0074] In an exemplary embodiment, the first signal transceiver module 224 includes a first pin and a second pin, the first pin is connected to the first connection line 221 , and the second pin is connected to the second connection line 222 .

[0075] In this embodiment, Figure 3 As shown, at least one input interface is connected to an external monitoring device, such as an axis temperature sensor, and the differential signal is transmitted through the first connection line 221 and the second connection line 222 to reach the first signal transceiver module 224. The first signal transceiver module 224 restores the transmitted signal according to the voltage difference between the first connection line 221 and the second connection line 222, that is, collects the differential signal.

[0076] It can be understood that the first connection line 221 and the second connection line 222 transmit differential signals in parallel.

[0077] Transmitting differential signals via first and second cables 221 and 222 improves interference resistance. In practical applications, electromagnetic interference is ubiquitous. When an interference signal simultaneously impacts both cables, the voltage changes generated by the interference signal on both cables are similar, as the interference experienced by both cables is essentially identical. When calculating the voltage difference, these identical interference components cancel each other out, ensuring signal integrity and accuracy. For example, in industrial environments where large-scale road maintenance machinery operates, there is a significant amount of electromagnetic noise. RS485 signals transmitted differentially can effectively resist this interference, ensuring reliable data transmission.

[0078] The differential signal is transmitted through the first connection line 221 and the second connection line 222. When the differential signal is transmitted, if there is no first matching resistor 223, the differential signal will be reflected, that is, reflection occurs between the first connection line 221 and the second connection line 222, interfering with subsequent signal transmission. Figure 3 R27, R28, and R30 are connected between the first connecting line 221 and the second connecting line 222 to match the line impedance with the output impedance of the monitoring device, absorb differential signal energy, prevent differential signal reflection, and ensure the integrity and accuracy of differential signal transmission.

[0079] In an exemplary embodiment, a diode (eg, Figure 3By using the diodes arranged opposite to each other and utilizing the unidirectional transmission characteristics of the diodes, the differential signal reflection between the first connection line 221 and the second connection line 222 is further prevented.

[0080] In an exemplary embodiment, a lightning protection circuit is connected between the first signal line 221 and the second signal line 222 .

[0081] In an exemplary embodiment, the first signal transceiver module 224 further includes an enable pin. Figure 3 The RE and DE pins in the first signal transceiver module 224 are connected. When the enable pin is at a low level, the first signal transceiver module 224 is in a receiving state and can receive data on the first connection line 221 and the second connection line 222; when the enable pin is at a high level, the first signal transceiver module 224 is in a sending state and can send data to the signal conversion module through the first connection line 221 and the second connection line 222.

[0082] The first signal transceiver module 224 transmits the differential signal to the signal conversion module 2. The differential signals transmitted on the first connecting line 221 and the second connecting line 222 have equal amplitudes but opposite polarities. For example, when the voltage on line A is +3V and the voltage on line B is -3V, the voltage difference between them is 6V. The signal conversion module determines the signal state by monitoring the voltage between the differential signals. If the voltage on line A is higher than that on line B, it represents a logical state, such as a normal differential signal. If the voltage on line A is lower than that on line B, it represents another logical state, such as a differential signal that is an alarm signal. Alternatively, if the voltage on line A is higher than that on line B and the voltage difference of the differential signal is 6V, it represents a logical state, such as a normal differential signal. If the voltage on line A is lower than that on line B, or the voltage difference of the differential signal is not 6V, it represents another logical state, such as a differential signal that is an alarm signal.

[0083] In an exemplary embodiment, the differential signal is an RS485 signal.

[0084] In an exemplary embodiment, the first signal transceiver module 224 may be a signal transceiver chip.

[0085] In some embodiments, the alarm device 4 includes a first alarm device and a second alarm device.

[0086] In some embodiments, reference Figure 3 As shown, the signal conversion module 2 is connected to at least one output interface with a relay module 23. The relay module 23 includes a first relay J1 and a second relay J2. The first relay J1 is connected to the signal conversion module 2 and the first alarm device, respectively. It is understood that the first relay is connected to the first alarm device via at least one output interface J1.

[0087] The second relay J2 is connected to the signal conversion module 2 and the second alarm device respectively. It is understandable that the second relay J2 is also connected to the second alarm device through at least one output interface.

[0088] The signal conversion module 2 is configured to: determine whether the switch signal is alarm information, output a control signal to the first relay J1 and control the first alarm device to alarm; determine whether the differential signal is alarm information, output a control signal to the second relay J2 and control the second alarm device to alarm.

[0089] In an exemplary embodiment, the first alarm device and the second alarm device may be sound and light alarms.

[0090] In an exemplary embodiment, a current limiting resistor is connected between the first relay, the second relay, and the signal conversion module to prevent a large current from flowing into the first relay J1 and the second relay J2, thereby providing protection.

[0091] In this embodiment, using the first relay J1 as an example, the signal conversion module 2 determines that the switching signal is an alarm signal and connects it to one end of the current-limiting resistor R10 via a wire. The other end of R10 is connected to the first relay J1. The first relay J1 is also connected to the first alarm device via at least one output interface. Figure 3 The first alarm device is indicated by L18.

[0092] Similarly, the signal conversion module 2 determines that the differential signal is an alarm signal in the second relay J2, and connects it to one end of the current limiting resistor R13 through another wire. The other end of R13 is connected to the second relay J2. At the same time, the second relay J2 is connected to the second alarm device through at least one output interface. Figure 3 The second alarm device is indicated by L17.

[0093] It should be noted that L18 and L17 are only schematic diagrams of the first alarm device and the second alarm device, and the first relay J1 and the second relay J2 are both connected to the first alarm device and the second alarm device through at least one output interface.

[0094] The monitoring efficiency of the monitoring device is improved by respectively giving alarms through different alarm devices, which helps to quickly confirm which monitoring device or type of monitoring device the source of the alarm signal appears on.

[0095] In some embodiments, a signal output module 24 is connected between the signal conversion module 2 and at least one output interface; the signal output module 24 includes a third connection line 241, a fourth connection line 242, a second matching resistor 243 and a second transceiver module 244, one end of the third connection line 241 and the fourth connection line 242 is connected to the signal conversion module 2, and the other end is connected to at least one output interface, the second signal transceiver module 244 is connected between the signal conversion module 2 and at least one output interface, and the second matching resistor 243 is connected between the third connection line 241 and the fourth connection line 242; the second signal transceiver module 244 is configured to send digital signals.

[0096] In an exemplary embodiment, the digital signal may be a differential signal.

[0097] In an exemplary embodiment, there may be one or more second matching resistors 243 .

[0098] In an exemplary embodiment, the third connection line 421 and the fourth connection line 242 transmit digital signals in parallel.

[0099] In this embodiment, Figure 3 As shown, the signal conversion module 2 determines that the switch signal or differential signal is an alarm message, and converts the alarm message into a digital signal. The digital signal is transmitted through the third connection line 241 and the fourth connection line 242 to reach the second signal transceiver module 244. The second signal transceiver module 244 converts the digital signal according to the voltage difference between the third connection line 241 and the fourth connection line 242, and transmits the digital signal to the display device 3 and the alarm device 4 through at least one output interface, and controls the monitoring screen and alarm information of the monitoring device 1 to switch to the display device.

[0100] Transmitting digital signals via third and fourth cables 241 and 242 improves interference resistance. In practical applications, electromagnetic interference is ubiquitous. When an interference signal simultaneously impacts both cables, the voltage changes generated by the interference signal on both cables are similar, as the interference experienced by both cables is essentially identical. When calculating the voltage difference, these identical interference components cancel each other out, ensuring signal integrity and accuracy. For example, in industrial environments where large-scale road maintenance machinery operates, subject to significant electromagnetic noise, RS485 signals transmitted using differential transmission can effectively resist this interference, ensuring reliable data transmission.

[0101] The digital signal is transmitted through the third connection line 241 and the fourth connection line 242. When the digital signal is transmitted, if there is no second matching resistor 243, the digital signal will be reflected, that is, reflection will be generated between the third connection line 241 and the fourth connection line 242, which will interfere with subsequent signal transmission. Figure 3R31, R32, and R33 are connected between the third connecting line 241 and the fourth connecting line 242, which can match the line impedance with the impedance of the display device 3, absorb digital signal energy, prevent digital signal reflection, and ensure the integrity and accuracy of digital signal transmission.

[0102] In an exemplary embodiment, a diode (eg, Figure 3 By using the diodes arranged opposite to each other and utilizing the unidirectional transmission characteristics of the diodes, reflection of digital signals between the third connection line 241 and the fourth connection line 242 can be further prevented.

[0103] In an exemplary embodiment, a lightning protection circuit is connected between the third signal line 241 and the fourth signal line 242 .

[0104] In an exemplary embodiment, the second signal transceiver module 244 further includes an enable pin. Figure 3 The RE and DE pins in the second signal transceiver module. When the enable pin is low, the second signal transceiver module 244 is in a receiving state and can receive data from the signal conversion module 2; when the enable pin is high, the second signal transceiver module 244 is in a sending state and can send data to at least one signal output interface through the third connection line 241 and the fourth connection line 242.

[0105] Signal conversion module 2 determines the signal status by monitoring the voltage between the differential signals. If the signal is an alarm signal, it transmits the alarm signal to second signal transceiver module 244 via third connection line 241 and fourth connection line 242. Second signal transceiver module 244 recovers the alarm signal based on the voltage difference between third connection line 241 and fourth connection line 242, and further transmits the alarm signal to display device 3 via at least one output interface. Signal conversion module 2 further controls the monitoring device 1 to switch the monitoring screen and alarm information to display device 3 via at least one output interface.

[0106] In some embodiments, an indicator light module 25 is further included, one end of which is connected to at least one indicator light, and the other end is connected to the first acquisition module 21, the second acquisition module 22, the relay module 23 and the signal output module 24 respectively through the signal conversion module 2, and is configured to display whether the signal conversion module, the first acquisition module, the second acquisition module, the relay module and the output module are working normally.

[0107] In an exemplary embodiment, the signal conversion module 2 includes a logic gate circuit.

[0108] In this embodiment, when the signal conversion module 2, first acquisition module 21, second acquisition module 22, relay module 23, and signal output module 24 are functioning normally, the logic gate circuit controls the corresponding logic switches (S15, S16, S17, S18, and S19) to close, and the indicator lights function normally. For example, when the first acquisition module 21 is functioning normally, the logic gate circuit controls the logic switch S16 to open, and the indicator lights connected to the first acquisition module 21 do not function properly. This allows for determining that the first acquisition module 21 is not functioning properly in acquiring digital signals, facilitating maintenance and repair.

[0109] In some embodiments, a power supply module 26 is further included, the input end of the power supply module 26 is connected to the vehicle power supply, and the output end of the power supply module is respectively connected to the signal conversion module 2, the first acquisition module 21, the second acquisition module 22, the relay module 23 and the signal output module 24; the power supply module 26 includes a rectifier bridge 261, a filter capacitor 263 and a first step-down module 262 connected in sequence, the rectifier bridge 261 is connected to the vehicle power supply and is configured to convert alternating current into direct current voltage; the input end of the first step-down module 262 is connected to the rectifier bridge 261, and the output end of the first step-down module 262 is configured to output direct current as a first working voltage; the filter capacitor 262 includes a first pole and a second pole, the first pole is connected between the rectifier bridge 261 and the first step-down module 262, and the second pole is grounded.

[0110] In an exemplary embodiment, the rectifier bridge 261 may be connected to a vehicle power supply via at least one input interface.

[0111] In an exemplary embodiment, the rectifier bridge 261 may be a bridge circuit composed of four diodes.

[0112] In this embodiment, a rectifier bridge 261 converts the AC power from the vehicle power supply into DC power, facilitating power supply to the signal conversion module 2, the first acquisition module 21, the second acquisition module 22, the relay module 21, and the signal output module 24. After voltage conversion, the DC power is filtered by a filter capacitor 263 to remove high-frequency and low-frequency ripple. The filtered DC power is then stepped down by a first step-down module 262 to output a first operating voltage sufficient to power the signal conversion module 2, the first acquisition module 21, the second acquisition module 22, the relay module 23, and the signal output module 24.

[0113] In an exemplary embodiment, filter capacitor 263 may include a large-capacity electrolytic capacitor and a small-capacity ceramic capacitor connected in parallel. The electrolytic capacitor is used to filter low-frequency ripple. Its first terminal is connected between the rectifier bridge and the first step-down module, and its second terminal is grounded. The ceramic capacitor is used to filter high-frequency ripple. Its first terminal is connected between the rectifier bridge and the first step-down module, and its second terminal is grounded. The electrolytic capacitor and ceramic capacitor together make the DC power smoother and more stable.

[0114] In an exemplary embodiment, the first buck module 262 may be a buck chip, such as an LTC3114 chip.

[0115] In an exemplary embodiment, an inductor is connected between the first step-down module 262 and the filter capacitor 263 for energy storage and further filtering.

[0116] In some embodiments, the power module 26 further includes a second step-down module 264 , the input end of the second step-down module 264 is connected to the output end of the first step-down module 262 , and the output end of the second step-down module 264 is configured to output the first operating voltage as a second operating voltage.

[0117] In an exemplary embodiment, the second buck module 264 can also be a buck chip, such as an LTC3114 chip.

[0118] In this embodiment, the first working voltage is not necessarily adapted to all modules in the signal conversion module 2, the first acquisition module 21, the second acquisition module 22, the relay module 23 and the signal output module 24. The first working voltage is further reduced to the second working voltage by the second step-down module 264 to adapt to one or more of the signal conversion module 2, the first acquisition module 21, the second acquisition module 22, the relay module 23 and the signal output module 24.

[0119] Exemplarily, the operating voltage of the signal conversion module 2, the first acquisition module 21, and the second acquisition module 22 is the first operating voltage, and the operating voltage of the relay module 23 and the signal output module 24 is the second voltage.

[0120] In an exemplary embodiment, the first operating voltage is 12V and the second operating voltage is 5V.

[0121] In some embodiments, one end of the first connecting line 221 connected to the first signal transceiver module 224 is connected to a first current limiting resistor 271, and the other end of the first current limiting resistor 271 is connected to the power supply module 16; one end of the second connecting line 222 connected to the first signal transceiver module 224 is connected to a second current limiting resistor 272, and the other end of the second current limiting resistor 272 is grounded.

[0122] In this embodiment, by connecting first and second current-limiting resistors 271 and 272 to first and second connection lines 221 and 222, respectively, the current flowing into the first signal transceiver module 224 and the signal conversion module 2 is limited, thereby preventing excessive current from damaging the first signal transceiver module 224 and the signal conversion module 2. When an abnormally high voltage or high current appears on the first and second connection lines 221 and 222, the first and second current-limiting resistors 271 and 272 can limit the current to a range that the first signal transceiver module and the signal conversion module can withstand, thereby protecting the circuit safety.

[0123] For the convenience of description, the above devices are described as being divided into various modules according to their functions. Of course, when implementing this application, the functions of each module can be implemented in the same or multiple hardware.

[0125] For example, the vehicle can be a large-scale road maintenance machinery and equipment, and the vehicle-mounted integrated data processing device is physically connected to the monitoring device (such as an axle temperature sensor), and is also physically connected to the display device and the alarm device. When an alarm signal such as the axle temperature being too high appears, the alarm signal and the monitoring screen of the monitoring device are switched to the display device, and the alarm device is controlled to alarm.

[0126] It can also be a household vehicle, where the on-board integrated data processing device is physically connected to a monitoring device (such as an infrared sensor), and is also physically connected to a display device and an alarm device. When it detects that the distance between an object and the sensor is less than a certain threshold, an alarm signal is generated, and the alarm signal and the monitoring screen of the monitoring device are switched to the display device, and the alarm device is controlled to sound an alarm.
