The following describes a water outlet control method and device for a fire fighting truck, the fire fighting truck and an electronic device built based on the water outlet control method for the fire fighting truck provided by the invention with reference to fig. 1 to 8.
Fig. 1 illustrates a water outlet control method for a fire fighting truck according to an embodiment of the present invention, where the fire fighting truck includes a water outlet driving member, at least two water outlets, and at least two water outlet valve assemblies; the water outlet driving piece is respectively connected with at least two paths of water outlets, and the water outlet valve assembly is arranged between each path of water outlet and the water outlet driving piece; the method can comprise the following steps:
step 101: respectively acquiring the working state of each water outlet valve component;
the working state of the outlet valve assembly in this embodiment mainly refers to an opening state, a closing state, and a fault state of the outlet valve assembly, and the fault state may be caused by the clamping of the outlet valve assembly or may be caused by the damage to the valve body of the outlet valve assembly.
In this embodiment, the execution main body of the water outlet control method for the fire fighting truck may be a controller, the controller may be a vehicle controller of the fire fighting truck itself, or may be a controller added to implement the control function.
Step 102: judging whether the water outlet valve assemblies work normally or not based on the working states of the water outlet valve assemblies to obtain a judgment result;
in this embodiment, if each of the outlet valve assemblies is in a normal operating state, it may be determined that the outlet valve assembly is operating normally, for example, each of the outlet valve assemblies is not in a failure state, that is, each of the outlet valve assemblies is in an open state or a closed state, which indicates that the outlet valve assembly is operating normally.
If an abnormal operating condition of the outlet valve assembly exists, such as a fault condition of the outlet valve assembly, the water valve assembly can be judged to be abnormal.
Step 103: matching a water outlet mode determining mode of the fire fighting truck based on the judgment result, and selecting the water outlet mode of the fire fighting truck through the water outlet mode determining mode;
