There are some problems associated with this data transmission scheme. Data adoption 485 bus transmitted by the speed is slower; the cable is laid for a long distance due to the excessive nodes, so that the technical difficulties of shielding, construction and the like are increased; the nodes are mutually independent and do not have an intelligent processing mechanism; the data of a plurality of nodes are simultaneously transmitted to the regional controller, so that line congestion is easy to occur, and the timeliness of data processing is reduced; when the data transmitted to the regional controller by the field executor device exceeds the dangerous threshold, the regional controller can only make a decision, but the field executor device cannot intelligently judge the abnormal situation and spontaneously make emergency operation.
In addition, the data transmission range of the existing pipe gallery mainly comprises subsystems, a monitoring backbone network and a monitoring platform, and real-time monitoring and specialized accident treatment on the internal operation condition of the pipe gallery can be realized. However, because multiple users including owners, factories and government monitoring departments have different knowledge demands on the operation condition of the pipe gallery, the prior art is not enough to realize the function of sharing all-dimensional data of the pipe gallery by multiple parties in the design of a data transmission mode.

if the difference is within the difference setting range, in step S460, the measurement data of the preceding stage controller 100c and the present stage controller 100a and the difference are transmitted to the succeeding stage controller 100b;
in step S470, the above-mentioned current level controller is used as a previous level controller, the above-mentioned process is repeated, the monitoring of all the node execution controllers is completed step by step, for example, as shown in fig. 2, when the measured data of each sensor of each node in the pipe gallery 1 is not in the set range of the difference value, the current level controller 100a and the next level controller 100b are transmitted step by step, wherein when the difference value is not in the set range of the difference value or the measured data is not in the set range of the difference value, the previous level controller 100c has another previous level controller 100c in the direction away from the area controller 10, the valves are sequentially screwed down in the order of being far from the area controller 10, and when the measured data is changed from the area controller 10, the valves are checked step by step, i.e. the nodes which are not in the same as the point where the measured data is changed from being close to being in the area controller 10, for example, the water line is not in the set up to be in the set range of the difference value, for example, if the water line is not in the point where the measured data is not in the set up to be in the same as the water line, and if the water line is not in the point where the water line is not in the set, and if the water line is not in the same condition, and if the water line is not in the state, and the water line is not in the condition of being completely different from the water line.
In the above monitoring method, the data is transmitted step by step when the data and the alarm signal are measured, and the data between the two adjacent nodes are compared by the execution controller 100, so that the pseudo alarm signal can be prevented, for example, when a certain area is constructed, the water pressures of a plurality of nodes in the area are lower than the set range, but the difference value of the water pressures of the adjacent nodes is within the difference value set range, and the maintenance is not required at this time.
In addition, in the above-described monitoring method, each preceding controller 100c before the current controller 100a in which an abnormality has occurred can be checked step by step, and the abnormality can be eliminated by the self-check, and even if the abnormality has not been eliminated, the preceding controller 100c in which an abnormality has occurred can be determined, and maintenance of all the preceding controllers 100c is avoided.
