DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wide-area comprehensive information collection system for collecting and transmitting life infrastructure information centering on various disaster prevention information in an area such as a municipal government, a plurality of municipalities, or prefectures. It is.

[0002]

2. Description of the Related Art FIG. 8 is a diagram showing a conventional information collecting system. For example, in the case of controlling the opening and closing of a sluice installed in a certain river while monitoring it at a remote location, conventionally, at the place where the sluice is installed, along with an observation device B for observing the water level, the state of the gate, etc., A monitoring device A is provided at a remote management office. A dedicated communication line C is connected between the two.
The monitoring device A sends a control signal to the observation device B side as necessary while acquiring observation data from the observation device B via the communication line C, and adjusts the opening and closing of the gate.

[0003] Such systems are not limited to water gate monitoring and control, and similar systems are individually employed in other information collection systems such as monitoring and control of snow removal equipment and road monitoring. In many cases, the cost is high even if the need for a monitoring system is high.

[0004]

However, in the above-mentioned conventional information collection system, a monitoring device A, an observation device B, and a dedicated communication line C are separately required for a floodgate, a snow removal facility, a road monitor, and the like. There was a problem that the initial equipment cost would be enormous. In addition, due to the low commonality between equipment, it is necessary to establish a separate maintenance and inspection system, and it is also necessary to upgrade the system individually, which increases the cost of maintenance and operation. Was.

[0005] Regarding the monitoring and control of snow removal equipment,
The number of snow removal pumps increased to several hundreds per municipality, making it impossible to perform economical remote monitoring and centralized monitoring, making it impossible to accurately control water discharge and stop water according to snow conditions. . In addition, monitoring and control of floodgates requires only one facility.
Since there were several dozen per municipalities, there was a problem that economical remote monitoring and centralized monitoring were not possible, and it was not possible to respond quickly even if a sudden change in water level occurred.

An object of the present invention is to solve such a problem, that is, to collect information on various objects to be monitored and control equipment at a significantly lower initial installation cost and maintenance and operation cost. It is assumed that.

[0007] In addition, economical remote monitoring, centralized monitoring and control of a large number of snow removal facilities and floodgates can be performed.
An object of the present invention is to enable quick response to a sudden change in water level, accurate water discharge according to the snow condition, and control of water stoppage.
