Description

Manhole Opening Watcher

The present invention relates to a manhole open alarm device, and more particularly to a manhole open monitoring system for guiding a manager by detecting the fact that the manhole is opened through a proximity sensor. Conventional manhole opening alarm device can only be installed by contacting with a micro switch of mechanical operation or installed from the inside of the manhole from the inside of the manhole to the outside of the manhole. Due to the inflow of rainwater or soil due to the nature of manholes installed on the top, there is a problem that the mechanical connection is fixed or the optical sensor is not smoothly operated and the detection function is lost at night.

  Unlike the installation environment of security devices of general buildings, the manhole environment buried on the road is not only poor due to the inflow of foreign matters, but also located on the road, resulting in communication failure due to unauthorized opening, unidentified fire, vehicle Even though the manhole cover was left open due to the impact, it was an obstacle to the development of an appropriate manhole alarm system despite the occurrence of life and vehicle accidents.

 Therefore, the present invention detects an open state as a proximity sensor when the manhole cover is opened to solve the above problems, posts an open state to the main control, transmits voice and text messages to the stored phone number, and opens and closes the manhole cover. It is possible to provide a manhole opening monitoring system that does not have any fear of breakage of the detection device and can operate even in the inflow of soil due to rainy weather and performs 24-hour real-time manhole opening monitoring without distinguishing between day and night.

The configuration and operation of the manhole opening monitoring system according to the present invention will be described with reference to FIGS. 1 and 2 as follows.

  First, the configuration of the manhole open monitoring device of FIG. 1 is basically composed of a main control device 200 and an open detection device 100, and is connected to a management PC 300 capable of managing the manhole open monitoring device by a separate program. It is configured to work together.

                   First, the configuration of the manhole to which the open detecting device 100 is installed will be described with reference to FIG. 5.

The manhole retractor 1 has a circular shape, the upper part of which is embedded in the road in equilibrium with the ground, covered with the manhole cover 2, and has a space configured to accommodate various cables therein. Manhole retraction (1) is composed of lid lining (8), packing lining (9), inner cover lining (10), dust receiving passage (4), rubber packing ring (PACKING RING) (5) and manhole cover (2) has a rubber packing ring (5) between the manhole opening (1), so they do not directly contact each other.

The configuration of the open monitoring device 100 for detecting the opening of the manhole cover 2 of the above configuration is as follows.

                  The open detection device 100 is composed of the same number of independent circuits as the proximity sensor 11 as many as the number of manholes accommodated in the main control device 200, each of the independent circuits are sensor ports ( SENSOR PORT) (66).

  The opening detecting device 100 is a device for detecting the opening of the manhole cover 2, the main sensor proximity sensor 11 is installed in each manhole, respectively, the arbitrary set on the lid seat jaw (8) After drilling the position is fixed to the plane and irregularities, and constitutes a circuit with the sensor port (66) of the main control device (200).

                In order to detect the manhole cover 2 efficiently, the proximity sensor 11 is perforated with a lid base jaw 8 of the manhole, and is embedded in a plane and irregularities, and is fixed to a high frequency oscillation type proximity sensor 11 that detects only metal objects. ) And a capacitive proximity sensor 11 capable of detecting all objects can be applied.

 In the example in which the proximity sensor 11 is installed and applied to the lid lining 8, only the manhole cover 2 made of metal should be detected without being affected by soil and other foreign substances. This is achieved by providing a high frequency oscillation type proximity sensor 11 capable of detecting only a metal body.

An embodiment of applying the proximity sensor 11 according to this embodiment together with another installation position for efficient detection of the proximity sensor 11 of the open detecting device 100 is as follows.

                In installing the proximity sensor 11, the packing settlement part 9, which is also circular, is drilled and fixed to be flush with the plane, but the proximity sensor 11 is in contact with the rubber packing ring 5 of the manhole cover 2. In addition, while detecting as a proximity sensor 11, it is achieved as a capacitive proximity sensor 11 capable of detecting all objects including metals and non-metal objects. When opening the manhole cover (2) also the rubber packing ring (5) embedded in the lid is also detached to detect the opening of the lid.

                Various foreign substances introduced between the manhole cover 1 and the manhole cover 2 are inserted into and fixed to the manhole cover 2 by a rubber packing ring 5 fixed to the proximity sensor 11 by the weight of the manhole cover 2. Since it is in close contact with each other, it is not detected and is not detected. When the rubber packing ring 5 is released from the manhole cover 2, it is detected as open.

Another embodiment of the open sensing device 100 will be described with reference to FIG. 7.

The proximity sensor 11 is installed, but the inner lid inner jaw (10) also made of a circular shape and fixed to be flat and uneven to be fixed as the proximity sensor (11), but the metal manhole cover (3) Since it is necessary to detect the open fact is achieved by installing a high-frequency oscillation type proximity sensor 11 that can detect only the metal body of the proximity sensor.

             Also open the manhole cover (2) and then open the manhole cover (3) to leave, immediately detect the open state, through the manhole cover (1) and the manhole cover (2) flow into the manhole cover (3) Various foreign matters such as earth and sand are not detected because the high frequency oscillation type proximity sensor 11 detects only metal.

                  As can be seen in the above embodiment, the method for drilling and installing the proximity sensor 11 in the perforated manhole retractor 1 includes a lid anchor jaw 8, a packing anchor jaw 9, and an inner lid that form a plane with the manhole lid. Since the proximity sensor 11 is buried in the flat jaw 10 unevenly, there is no direct contact with the manhole cover of the middle, so there is no risk of breakage.

                     In addition, since the operating voltage of the proximity sensor 11 configured in the open sensing device 100 is 10v to 30v, the range of the operating voltage is very wide, and the allowable voltage drop width is also very large, so that the main device 200 and the open sensing device 100 are provided. A long distance that can be separated from the main control unit 200 can detect the opening of the lid of the manhole located at a long distance.

                     In FIG. 2, the main controller 200 for controlling the overall operation of the opening detecting apparatus 100 includes a ROM 52 which stores a U-PROCESSOR 50 and a predetermined operation program. RAM (53) for temporarily storing data generated during the execution of the operation program, FLASH MEMORY (54) for allocating to program storage (PROGRAM STORAGE) and data storage (DATA STORAGE), sequential operation It consists of a timer (timer) 51 and the main control unit 200 is a LAN modem (61) for interworking with a computer, a telephone modem (TELEPHONE MODEM) 62 connected to a landline telephone MOBILE MODEM (63) connected to the PC, USB PORT (64) for data input, DISPLAY CENTER (65) for visually displaying alarm status, open of sensing device Sensor port (SENSOR PORT) (66) And it is composed of a buzzer 67, the speaker 68 to audibly inform the alarm state.

                                 In particular, the main control unit 200 is stored one or more telephone numbers, the telephone number is the telephone number of the administrator to be able to know the facts of the manhole cover open alarm and when the circuit abnormalities can be changed.

In addition, referring to FIG. 4, an embodiment of the main controller 200 will be described.

When the number of monitoring manholes is large, each alarm state cannot be posted due to the limit of the panel area of the main controller 200, so that the auxiliary control device 250 can be posted as shown in FIG. While controlling the open detection device 100, only the telephone modem (TELEPHONE MODEM) 62 and the mobile modem (MOBILE MODEM) 63 is configured by deleting.

This configuration is to allow only the main controller 200 to notify the administrator of the fact of alarm through each modem, and unnecessary communication other than the one telephone modem 62 and the mobile modem 63, respectively. This is to prevent unnecessary expenses by excluding the subscription.

Also,

 The above configuration is to post the alarms of each manhole visually and audibly, as well as on the management PC, and can be confirmed by double notification to receive text and voice messages, so that the alarm can not be recognized It is in accordance with the essential purpose of the present invention to prevent accidents.

Next, referring to FIG. 7, the operation of the open monitoring function of the manhole opening monitoring device will be described in detail.

When the opening of the manhole cover 2 is sensed in the opening detecting device, the opening detecting device 100 achieves the transmission of the sensing data according to the opening detection to the main controller 200. The open sensing device 100 is connected to the main controller 200 through a data transmission line to perform the data transmission.

 The open sensing data transmitted from the open sensing device 100 is input through the sensor port 66, which is a sensing data input unit, and the input sensed data is processed by the U-PROCESSOR 50. Visually posts to the display center (LEDS) 65, the display unit (65) according to the command, and the acoustic alarm with the speaker (67) and buzzer (68). Post it.

 At the same time, the alarm status is transmitted as voice and text messages to a designated telephone number through a telephone modem 62 and a mobile modem 63. Managers who receive this alarm status will take prompt action upon opening the manhole.

The operation of the alarm and the main control unit 200 as described above can be linked with the integrated management PC connected to the LAN PORT (61) and USB port (USB PORT) (64), and the alarm facts to the management PC Stored.

Looking at an embodiment of the additional configuration with respect to the operation of the main controller 200

 If the number of monitoring manholes is large, an auxiliary control device 250 is provided between the open detection device 100 and the main control device 200 as shown in FIG. 4 to control the open detection device 100, and the main control device ( Alerts not posted due to the limit of the posting area of 200) are to be posted to each of the auxiliary control device 250, but these alarms are transmitted to the main control device 200 to respond and text through the two modems (62, 63) Notification of the message is made in the main control unit 200.

In addition, the integrated management PC 400 can also be linked to the PC in the remote area via a dedicated line. The operation of this PC is operated by a separate program.

 Referring to Figure 8 describes the performance of the alarm monitoring function of the manhole opening monitoring system.

              The main controller 200 performs an alarm monitoring function when power is supplied.

              For example, when receiving 20 manholes in the main control unit 200, as described above, the sensor 11 of each manhole continuously transmits the lid closing detection data to the 20 sensor ports 66 of the main control unit 200. This indicates the normal state of the manhole.

Looking closely at the above process,

                       The U-PROCESSOR asks the 20 sensor ports 66 in the same order, "Is the 20 manhole?" Which is the last manhole number of the receiving manhole. Sensor port 11 outputs a “No” signal, and the input of this output is a U-processor.

(U-PROCESSOR) (50) asks “Port 1 alarm?”. At this time, since all 20 manhole covers 2 are closed, “No” is output. As the input of this output, the U-PROCESSOR 50 sequentially increases the port number, that is, the next 2 Ask manhole. If “No. 20 manhole?” Is displayed again, “No” signal is displayed. If “No. 2 port alarm occurs?”, And if “No” is output again, port number is sequentially increased, and the process proceeds to 19 as described above.

                     When the sensor port 66, which is the last accommodating manhole, asks “20? Is the manhole 20?”, The output is “Yes” and is terminated.

                  In this continuous open monitoring state, when the lid 2 of the 15th manhole is opened and the open sensing data output from the proximity sensor 11 of the 15th manhole is input to the 15th sensor port 66, the question cycle “ 15 port alarm occurrence? And the signal "Yes" is output by the open detection data, the following alarm fact is posted on the main control unit 200.

1.The corresponding alarm alarm LED blinks 15 times.

2. Alarm buzzer sounds.

3. Broadcasting “No. 15 manhole opening alarm” to the speaker

4. Post number 15 on the display unit

 In addition, a voice message of “15 manhole opening alarm generation” is transmitted to a telephone number stored through a telephony modem 62 of the main controller 200, and a telephone stored through a mobile modem 63. Send a text message of "No. 15 manhole opening alarm" to the number.

                      The reset of the alarm state may be made according to the recovery command of the U-PROCESSOR 50 according to the operation of the administrator, and also by the closing of the manhole cover 2.

Next, a circuit fault monitoring function will be described with reference to FIG.

                     In the normal state of the open monitoring state as described above, the breakage of the short-circuit or the detection sensor 11 is different from the open and closed states of the manhole cover 2, and as shown in FIG. Since the sensing device 100 cannot transmit / receive between the sensor ports 66 of the main control device 200, the U-PROCESSOR 66 does not have an input of the corresponding sensor port 66. Status alarm occurs ”.

 For example, if there is a short circuit in the 13th manhole or the detection sensor 11 is broken, ask the “13th manhole circuit condition alarm?”

                    As shown in FIG. 8, the signal “Yes” is outputted, and the main controller 200 posts the following alarm fact.

1. Alarm LED blinks for circuit no.15

2. Alarm buzzer sounds.

3. Broadcasting "No. 15 manhole circuit alarm" to the speaker

4. Post number 15 on DISPLAY UNIT

          In addition, the voice message of "an alarm occurrence of a manhole circuit abnormality no. 15" is transmitted to the telephone number stored through the telephone modem (TELEPHONE MODEM) 62 of the main controller 200,

The mobile phone transmits a text message of "15 manhole circuit abnormality alarm" to the stored telephone number through the mobile modem 63.

The reset of the alarm state may be performed according to the recovery command of the U-PROCESSOR 50 according to the operation of the administrator, and also according to the recovery of the circuit and the detection sensor 11.

Meanwhile, in the detailed description of the present invention, a specific embodiment has been described.

 Various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the claims below but also by the equivalents of the claims.

As described above, the present invention has a simple proximity sensor-type sensing device considering the characteristics of the manhole, which is difficult to install a separate device due to the inflow of groundwater and frequent inundation into rainy weather and a lot of soil inflow and difficult installation of a separate power source. Even when the manhole cover is opened or closed, there is no risk of breakage without contact, and the manhole cover is not damaged by opening and closing. The manhole cover can be monitored in real time for 24 hours in real time. This can prevent the accident risk of traffic vehicles because it can quickly recover by receiving the alarm of the manhole cover which is opened due to the impact of the vehicle as well as the protection of major communication facilities such as optical cables.
