The purpose of the underground area is to improve the cityscape, to preserve the road structure, and to facilitate traffic by collecting electricity, gas, water supply facilities, communication facilities, and sewage facilities.

However, the underground district plays an important role in running the city, and at the same time, it is located in the underground environment where the environment is poor. Therefore, there is a problem that a lot of manpower and budget are required for maintenance and management of the underground area.

Therefore, various systems have been developed to efficiently manage the underground sphere.

First, in order to manage and manage the underground facilities, we systematically manage information about various facilities (underground and underground water, telecommunication cables, power lines, water pumps, ventilators, etc.) A geographical information management system based on Geographic Information Systems (GIS) has been developed.

In order to monitor the situation inside the underground, various sensors were installed inside the underground, and an underground monitoring system was developed to confirm the alarms transmitted from the sensors in real time.

However, in the case of the above-mentioned system, the alarm transmitted from the sensor installed in the underground is located at a deep place (30 m or more), and in many cases it is a malfunction due to the poor position of the underground which is several hundred meters to several tens of kilometers in length It is not easy for the manager to make an accurate judgment on the alarm occurrence situation, and if the alarm occurrence situation is mistaken, serious damage occurs.

The present invention is further characterized in that a motion speed adjusting means 6 is further provided and is formed at the lower end of the actuator 3 so as to form a plurality of fitting holes 6a in the actuator 3, The movement speed of the actuator 3 can be adjusted by inserting a weight adjusting pin 6b for adjusting the weight of the actuator in the hole.

That is, the weight adjusting pin 6b is inserted into the fitting hole 6a. If one weight adjusting pin is provided, the working rod is light and thus it is possible to flow rapidly. When the three weight adjusting pins are installed, Slow flow is possible.

The movement speed control means controls whether the movement of the actuator 3 is fast or slow. If the actuator 3 moves too fast, the sensitivity increases. If the actuator 3 moves too slowly, So that the user can selectively control the movement of the actuator 3.

That is, if the user wants to increase the sensitivity, only one weight control pin 6b is inserted and coupled, and if the sensitivity is to be lowered, up to three weight control pins 6b are inserted and coupled.

It is needless to say that the number of the fitting holes 6a and the weight adjusting pins 6b may be varied according to need. In the embodiment of the present invention, three fitting holes 6a and three weight adjusting pins 6b ), So that the explanation can be made more convenient.

In addition, according to the present invention, when dust is detected as a reference or more and a notification condition occurs, the control unit 3000 displays the notification status through the automatic communication signal output unit 1000 so as to promptly solve the problem, The first switching transistor sw1 and the second switching transistor sw2 are connected in parallel to the power supply line 1110. The power supply unit 1110 includes a power supply unit 1110, a first switching transistor, a second switching transistor, a third switching transistor, a fourth switching transistor, A second circuit connection switch (sw2), and a communication control section (1120).

The power source unit 1110 applies power to its own power source.

The first switching transistor Q1 switches the circuit according to a switching signal input to the base.

The second switching transistor Q2 operates in accordance with the operation of the first switching transistor and switches the power source output from the power source unit.

The third switching transistor Q3 switches the circuit according to a switching signal input to the base.

The fourth switching transistor Q4 is provided on the other side of the output terminal of the power supply unit to switch the power supply unit output from the power supply unit.

The relay switch RL1 is coupled to the output terminal of the fourth switching transistor and generates a magnetic force when the fourth switching transistor is switched.

The first circuit connection switch sw1 performs a function of energizing the circuit by pulling the iron piece by the relay switch.

The second communication signal output power switch sw2 serves to induce a communication signal to be output through the communication signal output unit 1150 by supplying power to the communication signal output control unit 1140 while the iron wire is pulled by the relay switch do.

The communication controller 1120 switches the third switching transistor and the fourth switching transistor to switch the relay switch so that the first circuit connection switch and the second communication signal output power switch are switched, A first circuit connection switch configured to switch the first switching transistor and the second switching transistor while turning off the switching transistor and the fourth switching transistor and to turn off the relay switch and simultaneously to be interlocked with the first switching transistor and the second switching transistor And maintains the communication state by continuing the switching state of the second communication signal output power switch.

In addition, the present invention is characterized in that it comprises a circuit board 1131 for operation, a wire piece 1132 for connection to a power supply for operating a communication signal control unit, a first resilient holding means 1133, a second resilient holding means 1134, (1133a), and a manual operation switch (1135).

The circuit-operating piece 1131 contacts the first circuit connection switch sw1 and relays the power delivered from the second switching transistor to continue the flow of power.

The communication signal output control unit power connection iron piece 1132 is designed to operate in conjunction with the circuit operation iron piece 1131. When the circuit operation iron piece 1131 is turned on, power is supplied to the communication signal output control unit 1140 Thereby inducing the communication device to operate.

The first elastic holding means 1133 is provided at the lower end of the circuit operation steel plate 1131 so that the first circuit connection switch sw1 and the circuit operation wire 1131 are always kept in the off state when the relay switch is not operated .

The second elastic holding means 1134 is installed on the upper portion of the first circuit connecting switch sw1 and is spaced apart from the first elastic holding means by a predetermined distance. When the relay switch is operated, the circuit breaker 1131 is pulled to be coupled with the first resilient holding means 1133 while the first resilient holding means is overlapped, and at the same time, the first circuit connecting switch sw1 is switched So that even if the operation of the relay switch is stopped, the state of attaching the circuit breaker 1131 continues to maintain the power supply state through the first switching transistor and the second switching transistor. At this time, when the circuit breaker 1131 is operated by the operation of the relay switch, the communication piece 1132 is automatically operated to output the communication signal to the outside.

The gap maintaining means 1133a guides the second elastic holding means 1134 and the first elastic holding means 1133 to be engaged with each other while maintaining a constant gap without being directly coupled to each other when the first elastic holding means 1134 and the first elastic holding means 1133 are engaged, 1133 and the second resilient holding means 1134 can be more smoothly separated from each other by the action of the gap maintaining means at the time of disassembly. If the gap maintaining means is not present, the first elastic holding means 1133 and the second elastic holding means 1134 are directly attached to each other, so that mutual separation becomes difficult later. Accordingly, in the present invention, the first elastic holding means 1133 and the second elastic holding means 1134 can be easily separated by further providing the gap holding means 1133a.

The manual operation switch 1135 is connected to a wire for circuit operation and a wire for connection to a communication signal output control unit. When the user operates the wire to interrupt the operation of the communication signal, So that the operation of the communication signal output unit is stopped so that the communication signal is no longer output.

Hereinafter, the operation of the communication signal automatic output unit 1000 will be described.

First, a control relation for outputting a communication signal will be described. In the control unit, a power is applied to the third switching transistor and the fourth switching transistor to operate the relay switch RL1. Accordingly, the first circuit connection switch sw1 and the communication signal output power switch sw2 are turned on by the operation of the relay switch, and the power is applied to the communication signal output control unit 1140 to display the communication signal.

When the first circuit connection switch sw1 is operated, the control unit interrupts the operation of the third switching transistor and the fourth switching transistor to cut off the operation of the relay switch, and simultaneously operates the first switching transistor and the second switching transistor.

On the other hand, if the operator turns off the first circuit connecting switch and the communication signal output power switch in the middle of outputting the communication signal, the control unit recognizes this, and then the third switching transistor and the fourth switching transistor are operated, It is possible to keep the closed circuit while moving the iron piece and at the same time return the power outputted to the communication signal control part 1140 to continuously operate the communication signal output part 1150.

That is, according to the present invention, if the notification factor is not solved, the communication signal is continuously output to induce the notification factor to be solved.

That is, when a switching signal is applied to the third switching transistor, the fourth switching transistor, the first switching transistor, and the second switching transistor in the control unit, the communication signal is automatically output by returning the power source again, It is possible to induce the operator to reliably solve the cause of the communication signal.

If it is no longer necessary to output a communication signal, the control unit no longer applies a power supply signal to the first switching transistor, the second switching transistor, the third switching transistor, and the fourth switching transistor. ) Can be manually operated by a user to interrupt the communication signal.
