The components and specific connection structure of all parts in the full circuit are not limited, and in a specific embodiment of the present application, as shown in fig. 2, a schematic diagram of one circuit control principle to which the method described in the present application is applied is shown, in which S1 is a change-over switch, and the change-over switch S1 can be automatically controlled and further has a manual gear. The different positions comprise three different positions, such as a change-over switch in 1# automatic, 2# automatic or manual (1 # manual or 2# manual), wherein 1# automatic indicates that the automatic control is mainly connected with the No. 1 water pump; when the change-over switch is at different positions, the situation of the paths in the full circuit is different, for example, when the 1# is automatic, the line connected by L1-03 is the path, the line connected by L1-109 is the path, the line connected by L1-209 is the path, and other lines are in the open circuit. It should be noted that fig. 2 is only an illustration of one circuit control schematic diagram, and the method described in the present application may also be applied to other circuits for controlling the operation of the water pump and collecting signals thereof.

Specifically, for example, with reference to fig. 2, any one point selected from the points 03, 109, and 209 is taken as a first available point, the upper ends of the points 03, 109, and 209 are all connected to the L1 line, the point 101 is taken as a second available point, the upper end of the point 101 is connected to the L1 line, any one of the points 05, 111, and 211 is taken as a third available point, the upper ends of the points 05, 111, and 211 are all connected to the L1 line, the upper ends corresponding to the first available point, the second available point, and the third available point are connected in parallel, and the common point of the parallel connection is on the L1 line, so that it is necessary to determine the path conditions in which the three available points are connected to the L1 line.

And for the wet node, when the node type is the wet node, connecting the wet node which is not connected to the water pump with a zero line, and acquiring access information and open circuit information of the full circuit when the change-over switch is in different positions in the power-on state after connection. When the remote monitoring end performs signal acquisition on a node, the signal acquisition on the trunk node needs to be compared with a previous state, and the path condition of the node at the previous position of the change-over switch is compared with the path condition of the node at the current position, so as to obtain whether the node is a path node and is an upper end point or a lower end point, and acquire the signal of the node. And for the wet node, the node at the end which is not connected with the water pump needs to be connected with a zero line, so that the circuit condition in the whole circuit can be acquired by electrifying, and the information comprising the broken circuit of the circuit formed between the nodes and the circuit formed between the nodes is the circuit and the information of the upper end point and the lower end point is included.
