The positive poles of the vehicle gateway and the 485 relay action unit are electrically connected to the normally open contacts of the first power-on relay J1, and the negative poles of the vehicle gateway and the 485 relay action unit are electrically connected to the negative busbar. When the first power-on relay J1 is turned on, the vehicle gateway and the 485 relay action unit are powered on. Five first branches and five second branches are configured between the positive busbar and the negative busbar.

[0024] Each first branch is respectively provided with a first action output coil, a first controlled power relay and a first vehicle-mounted external device; the output contact pair corresponding to the first action output coil is respectively electrically connected to the positive bus and one end of the coil of the first controlled power relay, the other end of the coil of the first controlled power relay is grounded, the first contact of the first controlled power relay is electrically connected to the positive bus, the second contact of the first controlled power relay on the first branch is electrically connected to the positive electrode of the first vehicle-mounted external device, and the negative electrode of the first vehicle-mounted external device is electrically connected to the negative bus;

[0025] The first vehicle-mounted external device is also provided with a state control terminal, and a second action output coil is provided between the state control terminal and the positive bus or the negative bus: when the second action output coil is located between the state control terminal and the negative bus, the contact pair corresponding to the second action output coil is electrically connected to the control terminal and the negative bus of the first vehicle-mounted external device respectively; when the second action output coil is located between the state control terminal and the positive bus, a second controlled power supply relay is additionally configured, and the contact pair corresponding to the second action output coil is electrically connected to the positive bus and one end of the coil of the second controlled power supply relay respectively, and the other end of the coil of the second controlled power supply relay is grounded; the first contact of the second controlled power supply relay is electrically connected to the positive bus, and the second contact of the second controlled power supply relay is electrically connected to the state control terminal of the first vehicle-mounted external device;

[0026] The car's central control sends an action signal to the second action output coil via the vehicle gateway and the 485 relay action unit, so that the state control terminal obtains the control signal, thereby changing the working state of the first vehicle-mounted external device in the powered-on state; each second branch is respectively configured with a third controlled power relay and a second vehicle-mounted external device. The car's central control sends an action signal to the third controlled power relay via the vehicle gateway to enable or disable the second vehicle-mounted external device;

[0027] A remote control unit and a busbar transfer switch are configured on the vehicle; when the transfer switch is in a normally closed state, the first action output coil, the second action output coil, and the coil of the third controlled power relay are energized respectively, and the vehicle central control adjusts the operating status of the first on-board external device and the second on-board external device through wireless communication via the on-board gateway and the 485 relay action unit; when the movable contact of the transfer switch is actuated, the transfer switch is electrically connected to the remote control unit.

[0028] Preferably, the automobile central control adjusts the working states of the first vehicle-mounted external device and the second vehicle-mounted external device through wireless communication. After the vehicle-mounted ignition is started, the first power-on relay J1 is closed, and the switch is in a normally closed state. The automobile central control drives the first vehicle-mounted external device and the second vehicle-mounted external device through the gateway or directly:

[0029] 1) After the vehicle is started, the IO port configured for the 485 relay action unit outputs a high level, enabling the third controlled power relay on the second branch and the second on-board external device, causing the vehicle's cabin light assembly, camera, warning light, siren, and lift lights to enter and maintain an operating state, indicating the vehicle's current position and outline, and illuminating a designated area near the vehicle through the lift lights.

The first position sensor signal is fed back to the vehicle's central control system through the 485 relay action unit and the on-board gateway.

[0030] 2) Then, the car central control sends a power-on command through the vehicle gateway, and the first action output coil of the 485 relay action unit is actuated, so that the coil of the first controlled power relay of the corresponding first branch is powered on, and the contacts of the first controlled power relay are closed, thereby powering on the front working lights, strobe lights, tilt screen, LED screen and laser lights, and each first vehicle external device enters the initial working state; the car central control edits the content displayed on the LED screen or tilt screen and sends it wirelessly to the LED screen or tilt screen;

The frequency of the laser light flashing state switches between set frequency discrete values; the state control terminal of the inverted screen implements sequential control through the contacts of the second action output coil and the coil of the second controlled power relay. The vehicle central control sends an action command through the vehicle gateway to rotate and raise the powered inverted screen and display content to the target behind the vehicle; second position sensors are respectively provided at the extreme positions of the inverted and raised positions of the inverted screen. The second position sensors are respectively electrically connected to the third sensor input terminal and the fourth sensor input terminal of the 485 relay action unit, and output a second position sensor signal for indicating the current position of the inverted screen. The second position sensor signal is fed back to the vehicle central control through the 485 relay action unit and the vehicle gateway; the laser light and the inverted screen respectively provide warning signals for nearby vehicles;

[0032] 4) When the first and second on-board external devices need to be shut down, the vehicle central control first sets the status control terminal through the 485 relay action unit, causing the laser light to exit the flashing state and the tilting screen to return to its initial horizontal tilting position. The 485 relay action unit then sets the first action output coil, causing the front working lights, strobe lights, tilting screen, LED screen, and laser lights to stop working. The 485 relay action unit then feeds back the current position of the tilting screen to the vehicle central control via the on-board gateway. The 485 relay action unit then sets the third controlled power relay to reset and stop the second on-board external device. The 485 relay action unit then feeds back the current position of the lift light to the vehicle central control via the on-board gateway. When the positions of the tilting screen and the lift light are correct, the vehicle is turned off, the first energized relay J1 is de-energized, and the system reset is complete.

[0035] (2) It provides a logic for the coordinated use of on-board devices and presets the linkage logic between multiple on-board external devices to avoid the inconvenience of turning on / off devices one by one;

DETAILED DESCRIPTION

[0045] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] External in-vehicle devices often have independent switches. Some in-vehicle devices require a dedicated APP to edit their content. The current operator can edit the content after downloading the APP, but after the operator is replaced, when the displayed content needs to be edited, the APP needs to be downloaded again, making it very inconvenient to adjust the content of the in-vehicle device. In addition, the in-vehicle device is usually not integrated with the vehicle's onboard computer, resulting in a low overall level of intelligence for the in-vehicle device. In view of this, Figure 1 As shown, on the one hand, the present invention provides a multi-mode vehicle-mounted equipment application vehicle system, including:

[0047] Several first vehicle-mounted external devices 100 are arranged on the top or side surface of the vehicle, and each of the first vehicle-mounted external devices 100 is equipped with a first controlled power relay; the first controlled power relay is used to reliably supply power to the first vehicle-mounted external devices 100.

[0048] The vehicle-mounted gateway 200 is used for wireless communication with the vehicle's central control system. The vehicle-mounted gateway interacts with the vehicle's central control system through wireless communication, which can simplify wiring harness layout.

[0049] The 485 relay action unit 300 is communicatively connected to the vehicle gateway 200, and the output contacts of the 485 relay action unit 300 are respectively electrically connected to the coils of the first controlled power relays of the plurality of first vehicle-mounted external devices 100; the 485 relay action unit 300 can realize state control of each first controlled power relay, that is, the low-level signal at the vehicle central control controls the high-level signal at the first controlled power relay.

[0050] The vehicle-mounted battery 400 is provided in the vehicle and is used to provide power to the first vehicle-mounted external devices 100 , the vehicle-mounted gateway 200 and the 485 relay action unit 300 ;

[0051] Among them, the 485 relay action unit 300 receives the input signal of the car central control through the vehicle gateway 200, maintains or changes the state of the output contact, and activates the first controlled power relay, thereby turning on, changing or turning off the working state of several first vehicle-mounted external devices 100.

[0052] The positive pole of the vehicle battery 400 is connected to the positive busbar, and the negative pole is connected to the negative busbar. A first power relay J1 is provided on the main line of the positive busbar. The normally open contact of the first power relay J1 is provided on the positive busbar. The coil of the first power relay J1 is electrically connected to the vehicle ignition via a knob switch. The power input terminals of the vehicle gateway 200 and the 485 relay action unit 300 are electrically connected to the normally open contact of the first power relay J1 and the negative busbar, respectively. When the normally open contact of the first power relay J1 is closed, the vehicle gateway 200 and the 485 relay action unit 300 are powered on.

[0053] like Figure 1 The 485 relay action unit 300 shown includes a plurality of first action output coils, a second action output coil, and a pair of output contacts corresponding to the first action output coils and the second action output coils; a plurality of independent first branches are arranged between the positive bus and the negative bus, and a first controlled power relay and a first vehicle-mounted external device 100 are respectively arranged on the plurality of first branches, the first contact of the first controlled power relay on the first branch is electrically connected to the positive bus, the second contact of the first controlled power relay on the first branch is electrically connected to the positive electrode of the first vehicle-mounted external device 100, and the first vehicle-mounted external device The negative electrode of the device 100 is electrically connected to the negative busbar, and a pair of output contacts corresponding to the first action output coil is electrically connected to the positive busbar and one end of the coil of the first controlled power relay, respectively. The other end of the coil of the first controlled power relay is grounded. When the vehicle central control sends a control signal through the vehicle gateway 200, the vehicle gateway 200 inputs the control signal into the first action output coil. The first action output coil drives the corresponding output contact pair to change state, thereby energizing the coil of the first controlled power relay on the first branch, further actuating the contacts of the first controlled power relay, and powering on the first vehicle-mounted external device 100.

[0054] Figure 1 The vehicle communication shown has three levels. The first level is the car central control; the second level is the vehicle gateway, inverted screen and LED screen, which are wirelessly connected to the car central control; the third level is the 485 relay action unit 300, which is connected to the vehicle gateway through a 485 communication cable.

[0055] The first vehicle-mounted external devices 100 are front working lights, strobe lights, inverted screens, LED screens or laser lights.

[0056] like Figure 2 Combine Figure 3 To illustrate the above content, there are five first branches between the positive busbar and the negative busbar, including:

[0057] On the first first branch, the contact of the first action output coil KG1 is electrically connected to the coil of the first controlled power relay J6, the contacts of the first controlled power relay are electrically connected to the positive bus and the positive pole of the strobe light respectively, and the negative pole of the strobe light is electrically connected to the negative bus;

[0058] On the second first branch, the contact of another first action output coil KG2 is electrically connected to the coil of the first controlled power relay J7. The contact of the first controlled power relay J7 is electrically connected to the positive bus and the positive pole of the laser lamp respectively.

[0062] like Figure 2 Combine Figure 3 As shown, a plurality of first vehicle-mounted external devices 100 are additionally provided with a state control terminal 101, and a second action output coil is provided between the state control terminal 101 and the positive bus or the negative bus;

[0063] When the second action output coil is located between the state control terminal 101 and the negative busbar, the corresponding contact pair of the second action output coil is electrically connected to the control terminal and the negative busbar of the first onboard external device 100. The laser light's control terminal 101 and the negative busbar are each electrically connected to a corresponding contact pair of the second action output coil KG3. The vehicle's central control sends an action switching command to the second action output coil KG3 via the onboard gateway and 485 relay action unit 300, changing the laser light's output mode, such as the flashing frequency.

[0064] When the second action output coil is located between the state control terminal 101 and the positive bus, a second controlled power relay is also configured. The contact pair corresponding to the second action output coil is electrically connected to the positive bus and one end of the coil of the second controlled power relay, and the other end of the coil of the second controlled power relay is grounded. The first contact of the second controlled power relay is electrically connected to the positive bus, and the second contact of the second controlled power relay is electrically connected to the state control terminal 101 of the first vehicle-mounted external device 100. Figure 2 Combine Figure 3 As shown, the output contact pair corresponding to the second action output coil KG7 is electrically connected to the positive bus and the coil of the second controlled power relay J11 respectively, and the contacts of the second controlled power relay J11 are electrically connected to the common end, the rising end or the falling end of the falling screen respectively, and the current posture of the falling screen is changed or maintained through the input of the second action output coil KG7.

[0065] like Figure 4 As shown, the vehicle is also equipped with several second-onboard external devices, including a camera, warning lights, sirens, lift lights, and a cabin light assembly. To centrally control each of these second-onboard external devices, four second branches are provided between the positive busbar and the negative busbar. Each of these second branches is equipped with a third controlled power relay and a second-onboard external device. One end of the coil of the third controlled power relay is electrically connected to the positive busbar, the other end of the coil of the third controlled power relay is grounded, the first contact of the third controlled power relay is electrically connected to the positive busbar, the second contact of the third controlled power relay is electrically connected to the positive electrode of the second-onboard external device, and the negative electrode of the second-onboard external device is electrically connected to the negative busbar.

[0069] In the fourth second branch, the first and second contacts of another third controlled power relay J2 are electrically connected to the positive busbar and the positive pole of the cabin light assembly, respectively, while the negative pole of the cabin light assembly is electrically connected to the negative busbar. The cabin light assembly specifically includes the cabin light, the left cabin light strip, and the right cabin light strip.

[0070] Each second onboard external device is also directly controlled by the 485 relay actuation unit 300. For example, the output level of the IO port of the 485 relay actuation unit 300 energizes the coil of the third controlled power relay J2, thereby powering each second onboard external device to a power-on or power-off state. In the present invention, the second onboard external device is a cabin light assembly, a camera, a warning light, a siren, or a lift light; the lift light is also communicatively connected to the onboard gateway 200.

[0071] like Figure 2 and Figure 3 To avoid situations where anomalies in the vehicle gateway 200 or 485 relay action unit 300 prevent wireless input through the vehicle's central control, this solution also provides a backup method for manually adjusting the vehicle's external devices. Specifically, the system is further configured with a remote control unit 500 and a bus switch 600. The normally open contact of the first power relay J1 is also electrically connected to the bus switch 600, which electrically connects the positive terminal of the vehicle battery 400 to the remote control unit 500. The remote control unit 500 is independently provided with a number of normally open remote switches K, which are electrically connected to the non-ground terminal of the coil of the first controlled power relay, the non-ground terminal of the coil of the second controlled power relay, or the status control terminal 101 of the first vehicle-mounted external device 100.

The positive electrodes of the vehicle gateway 200 and the 485 relay action unit 300 are electrically connected to the normally open contacts of the first power-on relay J1, and the negative electrodes of the vehicle gateway 200 and the 485 relay action unit 300 are electrically connected to the negative busbar. When the vehicle ignition is turned on, the vehicle gateway 200 and the 485 relay action unit 300 are powered on. Five first branches and five second branches are configured between the positive busbar and the negative busbar.

[0085] Among them, each first branch is respectively configured with a first action output coil, a first controlled power relay and a first vehicle-mounted external device 100; the output contact pair corresponding to the first action output coil is respectively electrically connected to the positive bus and one end of the coil of the first controlled power relay, the other end of the coil of the first controlled power relay is grounded, the first contact of the first controlled power relay is electrically connected to the positive bus, the second contact of the first controlled power relay on the first branch is electrically connected to the positive pole of the first vehicle-mounted external device 100, and the negative pole of the first vehicle-mounted external device 100 is electrically connected to the negative bus.

[0087] The car central control sends an action signal to the second action output coil via the vehicle gateway 200 and the 485 relay action unit 300, so that the state control terminal 101 receives the control signal, thereby changing the working state of the first vehicle-mounted external device 100 in the powered-on state. Each second branch is respectively configured with a third controlled power relay and a second vehicle-mounted external device. The car central control sends an action signal to the third controlled power relay via the vehicle gateway 200 to enable or disable the second vehicle-mounted external device.

[0088] A remote control unit and a busbar transfer switch are configured on the vehicle. When the transfer switch is in a normally closed state, the first action output coil, the second action output coil, and the coil of the third controlled power relay are energized respectively. The vehicle central control adjusts the operating status of the first onboard external device 100 and the second onboard external device via wireless communication via the onboard gateway and the 485 relay action unit. When the movable contact of the transfer switch is actuated, the transfer switch is electrically connected to the remote control unit. The remote control unit includes a plurality of normally open remote control switches. The normally open remote control switches are electrically connected to the non-grounded end of the coil of the first controlled power relay, the non-grounded end of the second controlled power relay, or the state control end of the first onboard external device 100. The normally open remote control switches are used to energize the coil of the first controlled power relay, the coil of the second controlled power relay, or drive the state control end of the first onboard external device 100, so as to realize manual input when the onboard gateway 200 or the 485 relay action unit 300 is abnormal. At this time, the normally open remote control switches adjust the operating status of the first onboard external device 100 and the second onboard external device.

[0089] The car central control adjusts the working status of the first vehicle-mounted external device 100 and the second vehicle-mounted external device through wireless communication. After the vehicle-mounted ignition is started, the first power-on relay J1 is closed, and the switch is in the normally closed state. The car central control drives the first vehicle-mounted external device 100 and the second vehicle-mounted external device through the gateway or directly:

[0090] 1) After the vehicle is started, the IO port configured for the 485 relay action unit 300 outputs a high level, enabling the third controlled power relay on the second branch and the second on-board external device, causing the vehicle's cabin light assembly, camera, warning light, siren, and lift lights to enter and maintain an operating state, indicating the vehicle's current position and outline, and illuminating a designated area near the vehicle through the lift lights. First position sensors are respectively provided at the horizontal lowering limit position and the raising limit position of the lift lights. The output end of the first position sensor is electrically connected to the first sensor input end and the second sensor input end of the 485 relay action unit 300, respectively, and outputs a first position sensor signal indicating the current lift light position. The first position sensor signal is fed back to the vehicle's central control system through the 485 relay action unit 300 and the on-board gateway 200.

[0091] 2) Then, the vehicle central control sends a power-on command through the vehicle gateway 200, and the first action output coil of the 485 relay action unit 300 is actuated, so that the coil of the first controlled power relay of the corresponding first branch is powered on, and the contacts of the first controlled power relay are closed, thereby powering on the front working lights, strobe lights, tilt screen, LED screen, and laser lights, and each first vehicle-mounted external device 100 enters the initial working state; the vehicle central control also directly communicates with the LED screen or tilt screen through the vehicle wireless WIFI network, edits the content displayed on the LED screen or tilt screen, and wirelessly sends it to the LED screen or tilt screen;

[0092] 3) The laser light and the inverted screen are respectively provided with a state control terminal 101; the state control terminal 101 of the laser light is electrically connected to the negative busbar through the contact pair of the second action output coil, and the car central control sends a laser light action instruction through the vehicle gateway 200, so that the first action output coil of the 485 relay action unit 300 is intermittently actuated, so that the laser light enters a flashing state, and the frequency of the laser light flashing state switches between the set frequency discrete values; the state control terminal 101 of the inverted screen realizes sequential control through the contacts of the second action output coil and the coil of the second controlled power relay, and the car central control passes The vehicle gateway 200 issues an action command, causing the powered-on tilting screen to rotate and rise, and display content to the target behind the vehicle; second position sensors are respectively provided at the tilting and raising extreme positions of the tilting screen. The second position sensors are respectively electrically connected to the third sensor input terminal and the fourth sensor input terminal of the 485 relay action unit 300, and output a second position sensor signal indicating the current position of the tilting screen. The second position sensor signal is fed back to the vehicle's central control via the 485 relay action unit 300 and the vehicle gateway 200; the laser light and the tilting screen respectively provide warning signals to nearby vehicles;

[0093] 4) When the first and second onboard external devices 100 and 200 need to be turned off, the vehicle central control first sets the state control terminal 101 via the 485 relay action unit 300, causing the laser light to exit the flashing state and the tilting screen to return to its initial horizontal tilting position. The 485 relay action unit 300 then sets the first action output coil, causing the front working lights, strobe lights, tilting screen, LED screen, and laser light to stop operating. The 485 relay action unit 300 then reports the current position of the tilting screen to the vehicle central control via the onboard gateway 200. The 485 relay action unit 300 then sets the third controlled power relay, resetting and stopping the second onboard external device. The 485 relay action unit 300 reports the current position of the lift light to the vehicle central control via the onboard gateway 200. When the positions of the tilting screen and the lift light are correct, the vehicle is turned off, and the first energized relay J1 is de-energized, completing the system reset. If the first action output coil or the second action output coil cannot be set through the 485 relay action unit 300, it is necessary to operate the bus switch 600, change to the remote control operation unit 500 operation mode, and turn off the corresponding vehicle-mounted external device.
