[0022] Working principle: when in use, the type of cleaning robot usually has two water tanks, one for storing clean water and one for storing sewage. Clean water is used for cleaning the floor, and sewage is sucked in by the suction cup. Real-time liquid level sensors are installed in the sewage tank and the clean water tank to monitor the water level in real time. This type of cleaning robot often needs to scan the environment before performing the cleaning task. When performing cleaning, the clean water will gradually be consumed, and the sewage will gradually increase. By setting a threshold value through the controller, when the clean water is lower than the set value or the sewage is higher than the set value, the cleaning robot will suspend the task and go to the set water supply and drainage point. At the water supply point, there will be a water faucet with an electromagnetic valve. The electromagnetic valve is controlled by a remote IO module, which communicates with the controller of the robot body through wireless communication. At the same time, a flow sensor is installed on the upper part of the electromagnetic valve to detect the flow of clean water. In this case, the flow sensor, the electromagnetic valve (which needs power in the open state), and the IO module all need to be powered. If wired power supply is used, it is too troublesome and the application scenario is limited. Therefore, a battery is added. The IO module sends the battery power to the controller through wireless network. When the battery power is low, an alarm will be sent. Request manual battery replacement. The sewage flow sensor on the sewage discharge mechanism also uses this method. A sewage liquid level sensor is installed on the sewage tank. When the sewage reaches the set value, the controller issues a drainage task and goes to the drainage point. After going to the drainage point, the in-place sensor of the sewage discharge port detects that it has arrived, and the electromagnetic valve at the bottom of the sewage tank will be opened to discharge the sewage to the sewage discharge mechanism. The sewage discharge mechanism is connected to the sewer. The sewage discharge mechanism is provided with a flow sensor, which is powered by a battery and transmits data to the robot controller through a wireless network. The amount of sewage discharged into the sewer can be calculated.
[0023] The water draining or adding also has the function of automatic ending, when the water volume reaches the set value, the liquid level sensor transmits the signal to the controller, the controller controls the IO module through the wireless network, controls the electromagnetic valve to close, the water adding task is completed, and the cleaning task is resumed. When the sewage is drained, the sewage liquid level sensor detects that the sewage liquid level is lower than the set value, and the set value is usually the sewage is drained, the controller will close the electromagnetic valve at the bottom of the sewage tank according to the detected liquid level sensor signal, and the cleaning task is resumed.
[0024] Through the liquid level sensor and the volume of the water tank, the increase and decrease of the sewage and clean water can be calculated, and through the flow sensor of the clean water tap and the flow sensor of the sewage mechanism connected to the sewer, it can be calculated whether the water adding and draining is consistent with the increase and decrease of the water in the water tank of the cleaning robot. Through this calculation method, it can be judged whether the water tank and related parts have leakage, and whether the water adding and draining is aligned with the hole, to prevent the problem of water on the site.
[0025] At the same time, in order to ensure the operation of water adding and draining, it is necessary to ensure that it is in place, and a position sensor is installed at the lower part of the sewage drain valve, the position sensor selects a photoelectric switch, which must be triggered by the reflection of the reflective sheet. When the cleaning robot reaches the sewage mechanism, the sensor beside the drain valve port irradiates the reflective sheet connected to the sewage mechanism of the sewer, and confirms that it is in place, then the controller confirms that it is in place, and opens the sewage electromagnetic valve. This step of adding clean water also uses this method, a photoelectric switch is installed near the faucet, and when the photoelectric switch irradiates the reflective sheet on the vehicle body, the position is confirmed and the clean water valve is started.

Therefore, the embodiments should be considered in all respects as illustrative and not restrictive, and the scope of the present application is defined by the appended claims rather than the foregoing description, and it is intended to encompass all changes falling within the meaning and scope of equivalents of the claims. Any reference signs in the claims should not be considered as limiting the claims involved.
