[0031] The trolley lifting frame 2 is provided with a vehicle-side wireless communicator 24, and the pool-side wireless communicator 42 and the vehicle-side wireless communicator 24 are wirelessly connected to the trolley wireless communicator 32. The vehicle-side wireless communicator 24 also includes a Bluetooth sensor, and through Bluetooth wireless communication, the pool-side wireless communicator 42 or the vehicle-side wireless communicator 24 can establish contact with the trolley wireless communicator 32 and provide route guidance.

[0032] The sewage suction truck 1 is provided with a power take-off controller 13 and a master controller 5. The power take-off controller 13 is an existing technology that can control the power take-off to obtain power from the engine and drive the vacuum pump to operate, and will not be described in detail here. The vehicle-side wireless communicator 24 and the pool-side wireless communicator 42 are wirelessly connected to the master controller 5, so that the vehicle-side wireless communicator 24 and the pool-side wireless communicator 42 can also establish wireless communication with the master controller 5, which is convenient for coordination with other control actions. The output end signal of the master controller 5 is connected to the power take-off controller 13 and the lifting frame controller 21, so that the power take-off controller 13 and the lifting frame controller 21 are also uniformly controlled by the master controller 5.

[0034] The sewage storage tank 11 is provided with a tank high-level sensor 12 , and the signal of the tank high-level sensor 12 is connected to the main controller 5 , so that the main controller 5 can monitor the storage amount of feces and sewage in the sewage storage tank 11 according to the alarm signal of the tank high-level sensor 12 .

[0035] A sewage suction solenoid valve 44 is provided between the pool side docking interface 41 and the sewage storage tank 4, and the sewage suction solenoid valve 44 signal is connected to the pool side wireless communicator 42, so that the main controller 5 can control the switch of the sewage suction solenoid valve 44 through the pool side wireless communicator 42 when sewage suction is started and ended, thereby cooperating with the sewage suction operation more conveniently.

[0036] The sewage suction vehicle 1 is provided with a lifting frame high position sensor 22 and a lifting frame low position sensor 23, and the signals of the lifting frame high position sensor 22 and the lifting frame low position sensor 23 are connected to the main controller 5, so that the main controller 5 can determine the position of the trolley lifting frame 2 according to the signals of the lifting frame high position sensor 22 and the lifting frame low position sensor 23, and send out the next signal accordingly.

[0037] In addition, the pool side wireless communicator 42, the interface clamping controller 43, the pool low level sensor 45 and the sewage suction solenoid valve 44 of this embodiment are also circuit-connected to a pool side power supply device, which can be connected to the mains or powered by solar energy.

[0038] like Figure 2 As shown, the sewage suction method of the sewage suction vehicle 1 without an operator operating the sewage suction system includes the following steps.

[0039] In the first step, after the sewage suction vehicle 1 stops, the master controller 5 sends a descending signal to the lifting frame controller 21, and the lifting frame controller 21 controls the trolley lifting frame 2 to descend to a low position. The master controller 5 can start the sewage suction operation control by turning on a mechanical button, etc. In addition, for the embodiment provided with the lifting frame low position sensor 23, after the trolley lifting frame 2 descends to a low position, the lifting frame low position sensor 23 triggers a signal and sends it to the master controller 5, and then the master controller 5 sends a stop signal to the lifting frame controller 21, and the trolley lifting frame 2 can stay in a low position.

[0040] In the second step, the master controller 5 sends a wireless signal to the pool side wireless communicator 42. The sending of the wireless signal can be executed simultaneously with the sending of the stop signal to the lifting frame controller 21 or after a slight delay. The pool side wireless communicator 42 communicates wirelessly with the trolley wireless communicator 32 and continuously sends a docking route signal.

[0041] In the third step, the trolley wireless communicator 32 sends a movement signal to the trolley movement controller 33 according to the docking route signal, and the trolley movement controller 33 controls the docking trolley 3 to detach from the trolley lifting frame 2 and move toward the pool side docking interface 41.

[0042] The fourth step, when the docking route signal ends, the vehicle-side docking interface 31 and the pool-side docking interface 41 form a docking. The trolley wireless communicator 32 sends a stop signal to the trolley movement controller 33, and the trolley movement controller 33 stops control. The pool-side wireless communicator 42 sends a clamping signal to the interface clamping controller 43, and the interface clamping controller 43 controls the pool-side docking interface 41 to clamp with the vehicle-side docking interface 31, and feeds back a clamping completion signal to the pool-side wireless communicator 42. For this embodiment, the pool-side wireless communicator 42 can simultaneously send an opening signal to the sewage suction solenoid valve 44, and the sewage suction solenoid valve 44 opens. The pool-side wireless communicator 42 wirelessly sends the clamping completion signal to the main controller 5, and the docking work is completed.

[0043] In the fifth step, the main controller 5 sends an opening signal to the power take-off controller 13 , and the power take-off controller 13 controls the power take-off and starts the sewage suction, so that the feces and sewage in the sewage storage tank 4 can be continuously sucked into the sewage storage tank 11 on the sewage suction vehicle 1 .

[0044] Step 6. After the sewage suction is completed, the master controller 5 sends a stop signal to the power take-off controller 13, and the power take-off controller 13 releases the power take-off and stops the sewage suction. For this embodiment, the completion of sewage suction can be achieved by the alarm signal triggered by the pool low-level sensor 45 or the tank high-level sensor 12. At the same time, the master controller 5 sends a wireless signal to the pool-side wireless communicator 42, and the pool-side wireless communicator 42 sends an unclamping signal to the interface clamping controller 43. The interface clamping controller 43 controls the unclamping and feeds back the unclamping completion signal to the pool-side wireless communicator 42. For this embodiment, the pool-side wireless communicator 42 also sends a closing signal to the sewage suction solenoid valve 44 at the same time, and the sewage suction solenoid valve 44 is closed. Then the pool-side wireless communicator 42 sends the unclamping completion signal to the master controller 5.

[0045] In the seventh step, the main controller 5 sends a wireless signal to the vehicle-side wireless communicator 24, and the vehicle-side wireless communicator 24 communicates wirelessly with the vehicle wireless communicator 32 and continuously sends a return route signal.

[0046] In the eighth step, the trolley wireless communicator 32 sends a movement signal to the trolley movement controller 33 according to the return route signal, and the trolley movement controller 33 controls the docking trolley 3 to move toward the trolley lifting frame 2.

[0047] Step 9. When the return route signal ends, the docking trolley 3 returns to the trolley lifting frame 2, and the trolley charging device 25 recharges the docking trolley 3. The trolley wireless communicator 32 sends a stop signal to the trolley movement controller 33, and the trolley movement controller 33 stops control. The vehicle-side wireless communicator 24 wirelessly sends a trolley arrival signal to the main controller 5. The main controller 5 sends a lifting signal to the lifting frame controller 21 according to the trolley arrival signal, and the lifting frame controller 21 controls the trolley lifting frame 2 to be lifted to a high position. For the lifting frame high position sensor 22 set in this embodiment, after the trolley lifting frame 2 is lifted to a high position, the lifting frame high position sensor 22 triggers a signal and sends it to the main controller 5. The main controller 5 controls the lifting frame controller 21 to stop, and the trolley lifting frame 2 stops at a high position. At this point, the sewage suction work is completed.

[0048] In this embodiment, the docking of the interface, the opening and closing of the sewage suction, the control of the height of the feces and sewage in the sewage storage tank 4, etc., are all automated control operations, which reduces the use of manpower, reduces the labor cost, and improves the sewage suction efficiency.
