And step S20, when the water temperature is lower than the preset freezing temperature, controlling a drain valve of the hydraulic module to be opened so as to drain the water in the water way.

The preset freezing temperature is specifically a critical water temperature which is preset and used for distinguishing whether a waterway of the hydraulic module has a freezing risk or not. When the water temperature is lower than the preset freezing temperature, the waterway is indicated to have a freezing risk; when the water temperature is greater than or equal to the preset freezing temperature, the water way does not have the freezing risk.

When the drain valve is opened, the drain port of the water channel is opened, and water in the water channel is drained from the water channel. The drain valve can be always kept in an open state, can be closed after being opened for a preset time and can be intermittently opened.

According to the control method of the hydraulic module provided by the embodiment of the invention, when the water temperature of the water channel is lower than the preset freezing temperature, the method indicates that the water channel has a freezing risk, and at the moment, the water in the water channel is discharged by opening the drain valve, so that the freezing of the water channel is fundamentally avoided, the situation that the water channel does not have heat supply for a long time can be effectively prevented, and the risk of pipeline damage in the hydraulic module is effectively reduced.

Specifically, a first water temperature of the water path can be detected at a first moment, a second water temperature can be detected at a second moment at intervals of a preset duration, and if the first water temperature and the second water temperature are both smaller than a preset freezing temperature, the water temperature can be considered to be smaller than the preset freezing temperature, and the duration is greater than or equal to the preset duration. Or, water temperature detection is carried out at certain time intervals within a preset time length to obtain water temperatures of a plurality of water paths, the water temperatures are all smaller than the preset freezing temperature, the water temperatures are considered to be smaller than the preset freezing temperature, and the duration is longer than or equal to the preset time length.

The waterway is prevented from freezing through the drainage operation when the water temperature is maintained below the preset freezing temperature for a long time, so that the accuracy of the waterway freezing risk is improved, and the accuracy of the waterway anti-freezing control is improved.

Further, in this embodiment, when the hydroelectric module is in the power-off state, the battery may be controlled to supply power to the water replenishing valve, and the water replenishing valve is closed when the power is supplied. Specifically, when the water temperature is greater than or equal to the preset freezing temperature in the power-on state or the power-off state of the hydraulic module, the water replenishing valve is in the power-off state, the drain valve is opened at the moment, and the waterway is in the water replenishing state; when the hydraulic module is in a power-off state and the water temperature is greater than or equal to the preset freezing temperature, the battery supplies power to the water replenishing valve, the water replenishing valve is automatically switched from an open state to a closed state when switched from the power-off state to the power-on state, and external water is injected into the waterway through the water replenishing port of the waterway to replenish water for the waterway. In this embodiment, when the water conservancy module cuts off the power supply, the spare battery through the water conservancy module supplies power and realizes the moisturizing in water route and block control to guarantee that the moisturizing valve can realize the water in the water route with the cooperation of drain valve completely fast under the water conservancy module outage state.

In this embodiment, through the above manner, after the hydraulic module is powered on, rapid water replenishment in the water channel is realized through the cooperation of the drain valve and the water replenishment valve, so as to ensure that the water amount in the water channel after the hydraulic module is powered on is ensured to rapidly enter a normal working state.

It should be noted that, in other embodiments, the battery is controlled to stop supplying power to the drain valve, and at the same time, the battery is controlled to maintain supplying power to the water replenishing valve for a preset time period and then stop supplying power.

Further, step S300 includes: when the hydraulic module is in a power-on state, executing the steps of controlling the battery to stop supplying power to the drain valve and controlling the battery to stop supplying power to the water replenishing valve of the hydraulic module, and controlling the battery to start a charging state; wherein the external power source charges the battery in the charging state. In this embodiment, after the hydraulic module is powered back on, the battery is charged by an external power supply in addition to the water replenishing to the water path, so that the battery has sufficient electric quantity when the hydraulic module is powered off next time, and the electric quantity required by the control of the drain valve and the water replenishing valve in the power-off state is ensured, thereby further effectively preventing the water path from being frozen.

Further, in this embodiment, after step S300, the method further includes: acquiring the duration of the battery stopping supplying power to the water replenishing valve; and when the duration is longer than the preset duration, controlling a water pump of the hydraulic module to be started so as to discharge the air in the water way. The duration here is specifically timed from when the battery starts to stop supplying power to the water replenishing valve. When the duration is longer than the preset duration, the water pump arranged on the water path is started, the air exhaust port is arranged on the water path, and when the water pump is started, air in the water path is exhausted from the air exhaust port.

In this embodiment, open through the water pump when the moisturizing reaches a certain duration and carry out evacuation control again, be favorable to avoiding in the water route the water yield too little to cause the water pump to damage avoid the air to stay in the water route and influence the normal operating of moisturizing efficiency and water conservancy module.
