Description

[Technical Field]

[0001] The present invention relates to a technique for detecting residual unreacted non-explosive demolition agents. [Background technology]

[0002] Conventionally, for the demolition of concrete structures in civil engineering works (tunnel excavation, land development, road construction, port construction, etc.) and urban redevelopment, explosives such as dynamite have been used for crushing, as shown in Patent Document 1.

[0003] Although this method of crushing explosives is useful and economical, not only is it necessary to obtain a consumption permit, but it also generates sudden high-level noise and ground vibrations in urban areas and nearby residential areas, which significantly limits its use.

[0004] Therefore, for the destruction of each of the above construction works under restrictive conditions such as vibration, a non-explosive demolition agent is used as shown in Patent Document 2. This non-explosive demolition agent uses an ignition device similar to an electric detonator to instantly destroy the material by the expansion pressure caused by the thermite reaction, and unlike explosives, does not generate shock waves.

[0005] However, due to a break in the wiring (leg wire) for supplying the electrical energy required for ignition, a cartridge containing unreacted non-explosive demolition agent (hereinafter referred to as a residual cartridge) may be produced.

[0006] To check the remaining cartridges, (1) As shown in FIG. 18, a method of confirming the presence of the wire (leg) 102 of the cartridge 100 of the non-explosive demolition agent and manually manipulating the wire 102; (2) As shown in FIG. 19, a fluorescent nylon cord 103 is attached when the cartridge 100 is installed, and the nylon cord 103 is manipulated by hand. has become publicly known.

[0009] In the conventional method of manually manipulating the wiring 102 or nylon cord 103 described above, depending on the shredding conditions, if the wiring 102 or the like is cut without being exposed above ground, or if it is buried under the shattered pieces, it may be difficult to check for remaining cartridges.

[0010] In cases where it is difficult to confirm the presence of residual cartridges, if a rock drill is used carelessly, the impact or blow may ignite the ignition device, causing an unintended reaction and making it impossible to ensure the safety of workers.

[0011] The present invention has been made to solve these conventional problems, and its objective is to improve worker safety by making it possible to detect unreacted residual non-explosive demolition agent at work sites regardless of the condition of the wiring (leg wires) or nylon cords.

[0013] (2) Another aspect of the present invention is a method for detecting residual unreacted non-explosive demolition agents by a detection device after burying a non-explosive demolition agent with an RFID tag attached to the object to be demolition, and reacting the non-explosive demolition agent. registering the unique information of the RFID tag in a control display unit of a detection device; After the construction, reading the unique information of the RFID tag with an antenna of the detection device; The method is characterized by having a step in which the control display unit detects the remaining non-explosive demolition agent by comparing the unique information of the RFID tag read by the antenna with the unique information of the registered RFID tag. [Effects of the Invention]

[0016] The following describes a non-explosive demolition agent residue detection device (residue detection method) according to an embodiment of the present invention. This detection device is used to detect residual cartridges during civil engineering work using non-explosive demolition agents, concrete structure demolition work, etc.

[0017] This non-explosive demolition agent is used for demolition in environments with constraints such as vibration, and examples include Lockrack (registered trademark) described in Non-Patent Document 3. This non-explosive demolition agent uses an ignition device like explosives, but it is instantly demolitioned by the expansion pressure caused by the thermite reaction, and unlike explosives, it does not generate shock waves.

[0018] Specifically, the demolition process of the construction work is carried out in accordance with the handling procedures for non-explosive demolition agents. In this case, a cartridge 100 of non-explosive demolition agent with an ignition device attached is inserted into a borehole 106 (see Figures 18 and 19) to be demolished, such as a rock body, and then a filler 105 is buried in the cartridge. After that, the ignition device is ignited with a dedicated igniter to cause the cartridge 100 to react.

[0019] However, as mentioned above, if a borehole in a rock body or the like is buried when the cartridge 100 reacts and the wiring 102 or nylon cord 103 is not exposed above ground, it is difficult to visually check for remaining cartridges, so the detection device is used to detect unreacted remaining cartridges. [Example]

[0020] 1 shows an embodiment of the detection device. The detection device 1 of this embodiment detects remaining cartridges by itself at the work site and notifies the worker of their presence.

[0021] The detection device 1 has an antenna disk 4, a transmitter / receiver unit 5, a power supply unit 6, and a holder 7 for a control display unit attached to a grip pole 2 bent in a crank shape.

[0022] More specifically, as shown in FIG. 2, an antenna disk 4 is rotatably attached to the tip of the grip pole 2, and a transmitter / receiver unit 5 is attached in front of the antenna disk 4.

[0023] 3, the holder 7 is attached to the crank 3 of the grip pole 2, and the power supply unit 6 is attached to the tip of the crank 3. The power supply unit 6 is connected to the transmitter / receiver 5 so as to be able to supply power and transmit and receive data, while the control display unit 8 is attached to the holder 7 as shown in FIG.

[0024] The control and display unit 8 is configured by a portable computer, and can be, for example, a handheld terminal such as that described in Non-Patent Document 1. After being attached to the holder 7, it is connected to the power supply unit 6 to perform the function of detecting and displaying remaining cartridges.

[0025] Here, the unique information (unique code) of the RFID tag 10 (see Figure 6) of each cartridge 100 used for crushing in the construction work is registered in the control display unit 8 using the tag data registration machine 11 of Figure 5.

[0026] That is, unique numeric data (serial number) is recorded as unique information on each RFID tag 10. In this embodiment, the remaining cartridge is detected by reading the unique information on the dedicated tag (RFID tag 10) using the automatic recognition function of RFID, i.e., radio waves.

[0027] The RFID tag 10 is a disk-shaped tag made of synthetic resin that contains a long-waveband read-only IC chip and a circular coil, and is driven by the power induced in the circular coil when it receives an alternating magnetic field generated by the antenna disk 4. At this time, a master clock is obtained from the alternating magnetic field, and the unique information written during the manufacturing process is sent back to the antenna disk 4 by switching the modulation current on and off.

[0028] In this embodiment, the back side of the RFID tag 10 is an adhesive surface, and as shown in Figures 6(a) and 6(b), during the construction work, the adhesive surface is attached to a cartridge 100 of non-explosive demolition agent. However, if the cartridge 100 ignites, it will be destroyed by the high heat generated, and the automatic recognition function will stop.

[0029] On the other hand, if the cartridge 100 remains without igniting, the automatic recognition function is maintained and it is detected by the detection device 1. The detection device 1 mainly includes an antenna disk 4, a transmitter / receiver unit 5, a power supply unit 6, a control display unit 8, and the registration device 11.

[0030] <Configuration example of main parts 4-6, 8, 11> 7 to 9, an example of the configuration of the antenna disk 4, the transmitter / receiver 5, the power supply 6, the control table 8, and the registration device 11 will be described. Here, the antenna disk 4 and the transmitter / receiver 5 are connected by a high-frequency coaxial cable, and as shown in FIG. 7, an RF (radio frequency) signal is transmitted between the two 4 and 5.

[0031] The transmitter / receiver unit 5 and power supply unit 6 are connected via a USB (registered trademark) cable, and the control and display unit 8 is connected to the power supply unit 6 via the USB cable after being attached to the holder 7. This allows DC power to be supplied from the power supply unit 6 via the USB cable to the transmitter / receiver unit 5, and also enables serial data communication between the two units 5 and 8. In this case, the control and display unit 8 can also be used as a backup power source.

[0032] When registering the unique information of the RFID tag 10, the registration device 11 and the control display unit 8 are connected by a USB cable. As a result, the unique information of the RFID tag 10 is transmitted and received by serial communication between the registration device 11 and the control display unit 8, as shown in FIG.

[0033] (1) Antenna disc 4 The antenna disk 4 includes a circular spider net coil 4a housed in a synthetic resin case, as shown in Fig. 9. This circular spider net coil 4a is made by winding a synthetic resin-coated copper wire 4c around an acrylic frame 4b.

[0034] The circular spider net coil 4a is adjusted to tune to a long wave frequency, and generates an alternating magnetic field when it receives a long wave high frequency signal (RF signal) from the transmitter / receiver 5.

[0035] Therefore, when an RFID tag 10 is present within the communication distance (up to 60 cm), the circular spider net coil 4a receives unique information from the RFID tag 10, which has obtained power from the alternating magnetic field. This allows the unique information of the RFID tag 10 to be read, and a modulated wave (RF signal) containing the unique information of the RFID tag 10 is sent to the transmitter / receiver 5.

[0036] (2) Transmitter / receiver 5 As shown in FIG. 7, the transmitter / receiver 5 includes an RFID reader (transmitter / receiver module) 5a, a serial data conversion circuit 5b, an antenna matching circuit 5c, a read display LED / buzzer drive circuit 5d, a buzzer 5e, and an LED 5f.

[0037] The module 5a generates a long-wave band high frequency signal to generate an alternating magnetic field, and outputs the unique information of the RFID tag 10 sent from the circular spider net coil 4a in "ASCII" format to the conversion circuit 5b. At the same time, it outputs an audio frequency detection signal to the drive circuit 5d, which then sounds the buzzer 5e and lights up the LED 5f in red.

[0038] The conversion circuit 5b receives the ASCII format signal output from the module 5a and converts it into a USB signal that can be read by a general-purpose computer such as a personal computer. The converted USB signal is sent as serial data to the control display unit 8 via the power supply unit 6.

[0039] When the control display unit 8 receives this serial data, it receives the unique information of the RFID tag 10 read by the circular spider net coil 4a of the antenna disk 4. The power supplied from the power supply unit 6 via the USB cable is distributed to each unit 5a to 5f, and impedance matching with the antenna disk 4 is achieved by the matching circuit 5c.

[0040] (3) Power supply section 6 The power supply unit 6 includes a constant voltage circuit 6a, a power on / off / source switch 6b, a battery (dry cell) 6c, a voltage monitoring circuit 6d, and an LED 6e. The battery 6c requires four alkaline dry cell batteries as the main power source for driving the detection device 1, and is housed in a battery case (not shown). The power supply unit 6 also includes a USB port P1 for sending and receiving serial data to and from the control display unit 6, and a USB port P2 for using the control display unit 6 as a backup power source.

[0041] Here, when the SW 6b is turned ON, the battery 6c is used as the power source, and DC voltage is supplied to the transmitter / receiver 5 via the constant voltage circuit 6a. In this case, the green LED 6e attached to the case of the power supply unit 6 is lit via the voltage monitoring circuit 6d. However, if the output voltage of the battery 6c falls below a specified voltage, the voltage monitoring circuit 6d turns off the green LED 6e to notify the user that power is being consumed.

[0042] On the other hand, when the SW 6b is turned OFF, no DC voltage is supplied from the battery 6c to the transmitter / receiver 5. However, if a USB cable is connected to the USB port P2, the battery 8a of the control display unit 8 is used as a backup power source, DC voltage is supplied to the transmitter / receiver 5 bypassing the constant voltage circuit 6a, and the yellow LED 6e attached to the case of the power supply unit 6 lights up. In this case, the voltage monitoring circuit 6d does not function, and the yellow LED 6e is not turned off even if the output voltage of the battery 8a falls below the specified voltage.

[0043] (4) Control display unit 8 The control display unit 8 is, for example, a handheld terminal with a 6-inch screen (see, for example, Non-Patent Document 1), and is equipped with the hardware resources (for example, CPU, RAM, ROM, SSD, HDD, etc.) and software resources (OS, applications, etc.) of a normal computer.

[0044] A table (not shown) for registering tag data is constructed in the storage device (RAM, SSD, HDD, etc.) of the control display unit 8. In this table, unique information of the RFID tag 10 of each cartridge 100 used for the crushing work is registered as tag data.

[0045] Usually, after the OS (Operating System) of the control display unit 8 is started, a dedicated application for the detection device 1 is automatically started. (A) The tag data in the table can be referenced to confirm the unique information of the RFID tag 10 of each cartridge used in the construction work; (B) By comparing the unique information of the RFID tag 10 read by the circular spider net coil 4a with the tag data registered in the table, it is possible to detect the remaining cartridge.

[0046] (5) Tag data registration machine 11 The tag data register 11 is connected to the control display unit 8 via a USB cable when registering the unique information of the RFID tag as described above, and includes an antenna 12 and a transmitter / receiver unit 13 as shown in FIG.

[0047] The antenna 12 is configured in a similar manner to the antenna disk 4 and includes a circular spider net coil 4a (see Figure 9) that is adjusted to tune to long-wave band frequencies, and generates an alternating magnetic field when it receives a long-wave band high-frequency signal from the transmitter / receiver 13.

[0048] Therefore, when the RFID tag 10 is held over the circular spider net coil 4 a, the RFID tag 10 obtains power from the alternating magnetic field, and receives the unique information from the RFID tag 10 , which then transmits the unique information to the transmitter / receiver 13 .

[0049] The transceiver 13 is configured almost the same as the transceiver 5 (except for the matching circuit 5c), and includes an RFID reader (transceiver module) 13a, a serial data conversion circuit 13b, a read display LED / buzzer drive circuit 13c, a buzzer 13d, and an LED 13e.

[0050] The module 13a generates a long-wave band high frequency signal to generate an alternating magnetic field, and outputs the unique information of the RFID tag 10 sent from the circular spider net coil 4a in "ASCII" format to the conversion circuit 13b. At the same time, it outputs an audio frequency detection signal to the drive circuit 13c, which then sounds the buzzer 13d and lights up the LED 13e.

[0051] The conversion circuit 13b receives the ASCII format signal output from the module 13a, converts the input signal into a USB signal that can be read by a general-purpose computer such as a personal computer, and transmits the converted USB signal to the control display unit 8 as serial data.

[0052] The transmitted serial data is received by the control display unit 8, which then receives the unique information of the RFID tag 10 read by the circular spider net coil 4a of the antenna 12. The unique information of the RFID tag received at this time is automatically registered as tag data in the table by the dedicated application.

[0053] The tag data register 11 is supplied with power by converting an AC power supply 21 into DC power using an AC adapter 20, and the power is distributed to each of the units 13a to 13e.

[0054] <<Remaining cartridge detection procedure>> The detection of the remaining cartridge by the detection device 1 is performed as follows: S01: Tag data registration S02: Attaching RFID tag 10 S03: Use of non-explosive demolition agents S04: Preparation for detection S05: Search for residual cartridges The process is carried out in the following steps. Each step (S01 to S05) will be described in detail below.

[0055] (1) Tag data registration (S01) When registering tag data in the control display unit 8, first, the power of the registration device 11 is turned on, and as shown in FIG. 10, it is connected to the control display unit 8 via a USB cable.

[0056] Next, the control display unit 8 is powered on, the dedicated application is started, and the monitor 8b (see FIG. 12) displays the initial screen 30 of FIG. 14(a). Here, the registration screen 30a in the initial screen 30 is selected, and the screen transitions to the registration screen 31 of FIG. 14(b).

[0057] In this state, when the RFID tag 10 attached to the cartridge 100 used in the construction work is held over the registration device 11, the unique information of the RFID tag 10 is transmitted as serial data to the control display unit 8 as described above.

[0058] When the control display unit 8 receives this, a list of the unique information of the RFID tag 10 is displayed on the display unit of the registration screen 31. After this list is displayed, by selecting the registration button 31b, the unique information of the RFID tag 10 is automatically registered as tag data in the table.

[0059] At this time, the tag data in the table can be deleted by selecting Reset 31c on the registration screen 31. Also, the tag data in the table can be displayed and checked by selecting the registration status confirmation screen 30b on the initial screen 30. After registering the tag data (S01), the user selects the TOP screen 31d to return to the initial screen, and then selects Exit 30d to close the dedicated application and proceed to S02 and subsequent steps.

[0060] (2) Attaching RFID tag 10 (S02) 11(a) and 11(b), when attaching the RFID tag 10, the backing 10a is peeled off in advance and attached to the upper end of the cartridge 100. At this time, it is preferable to reinforce the RFID tag 10 with tape (not shown) to prevent it from falling off when attached.

[0061] (3) Use of non-explosive demolition agents (S03) The demolition process of the construction work is carried out in accordance with the handling procedure for the non-explosive demolition agent. That is, as described above, the cartridge 100 of the non-explosive demolition agent with the ignition device attached is inserted into the borehole 106 of the rock body or the like to be demolished, while being careful not to drop the RFID tag 10. Filling 105 is embedded therein. In this state, the ignition tool is ignited by a dedicated igniter to make the cartridge 100 react.

[0062] (4) Preparation for detection (S04) When detecting residual cartridges, please prepare in advance. - Mounting and connecting the control display unit 8 (S04-1) Activation of the detection device 1 (S04-2) Start-up of control display unit 8 (S04-3) Perform the following work.

[0063] S04-1: The installation and connection work for the control and display unit 8 will be explained with reference to Fig. 12. Here, as shown in Fig. 12(a), the control and display unit 8 for which tag data registration has been completed is installed in the holder 7. Then, as shown in Fig. 12(b), the control and display unit 8 and the USB port P2 of the power supply unit 6 are connected with a USB cable. At this time, if the battery 8a of the control and display unit 8 is used as the power source, the USB port P1 on the power supply unit 6 side is used.

[0064] S04-2: The startup state of the detection device 1 will be described with reference to Fig. 13. In Fig. 13(a) and (b), 6e-1 indicates a yellow LED 6e provided in the power supply unit 6, and 6e-2 indicates a green LED 6e provided in the power supply unit 6, and Fig. 13(a) shows the LEDs 6e-1 and 6e-2 in an unlit state.

[0065] 13(b), when the SW6b of the power supply unit 6 is turned on, the LED 6e-2 lights up, power is supplied from the battery 6c to the transmitter / receiver 5, and the detection device 1 starts up. If the LED 6e-2 does not light up even when the SW6b is turned on, the dry cells of the battery 6c have run out, so replace the dry cells.

[0066] On the other hand, when the battery 8a of the control display unit 8 is used as the power source, by switching the SW6b to OFF and connecting via USB to the USB port P1, the detection device 1 can be started using the battery 8a as a backup power source. In this case, the yellow LED 6e-1 lights up at the same time as the detection device 1 starts up.

[0067] S04-3: When the power to the control display unit 8 is turned on, the dedicated application is automatically started after the OS starts, and the initial screen 30 is displayed. At this time, by selecting the search screen 30c from the initial screen 30, the screen transitions to the search screen 32 of Fig. 14(c), and the process proceeds to the search for remaining cartridges in S05.

[0068] (5) Inspection of residual cartridges (S05) The principle (method) of searching for remaining cartridges will be described with reference to FIGS. During crushing work, as shown in Figure 15(a), a cartridge 100 equipped with an ignition device is inserted into a borehole 106 for crushing a rock mass or other object, and a filler 105 is embedded in the hole. In this state, the ignition device is ignited by a dedicated igniter, causing the cartridge 100 to react.

[0069] However, if the ignition device is not activated and the cartridge 100 remains unfired, the RFID tag 10 attached to the top surface of the cartridge 100 will not be destroyed and will remain in that state, as shown in Figure 15(b).

[0070] At this time, the alternating magnetic field generated by the circular spider net coil 4a of the antenna disk 4 penetrates about 40 to 50 cm into the ground directly below it (see the arrow in Figure 16). However, if there is no RFID tag 10 directly below it (see Figure 16(a)) or if the RFID tag 10 is destroyed, the unique information cannot be read and the detection device 1 does not react.

[0071] On the other hand, when the detection device 1 is moved and a residual cartridge is found directly below the range of the antenna disk 4, as shown in Figure 16(b), the RFID tag 10, which is powered by the alternating magnetic field, functions and returns unique information to the antenna disk 4.

[0072] As a result, the unique information of the RFID tag 10 is read by the antenna disk 4 and sent to the transceiver 5. At this time, as shown in Figure 17(b), the LED 5f is lit in red by the drive circuit 5d, and a 3.1 kHz buzzer sound is output from the buzzer 5e for about one second to notify the user that a remaining cartridge has been detected. Note that Figure 17(a) shows the state in which the LED 5f is not lit.

[0073] Furthermore, the control display unit 8 receives the unique information of the RFID tag 10 read by the circular spider net coil 4 a of the antenna disk 4 via the transmitter / receiver unit 5 and the power supply unit 6 .

[0074] At this time, the control display unit 8 compares the unique information of the received RFID tag 10 with the unique information of the tag data registered in advance in S01. If the comparison results in a match between the two unique information, the matching unique information is displayed on the display unit 32a of the exploration screen 32 in Fig. 14(c). This allows the user to understand that the cartridge 100 used in the construction work remains as a residual cartridge in the rock body or other object to be crushed.

[0075] As a result, by sequentially searching with the alternating magnetic field of the antenna disk 4, it is possible to detect the remaining cartridge even if the wiring 102, nylon cord 103, etc. are cut without being exposed above ground, or even if they are buried under debris.

[0076] Therefore, the detection device 1 can detect remaining cartridges regardless of the state of the wiring 102 and nylon cord 103, thereby ensuring the safety of workers. Note that selecting reset 32b in Figure 14(c) erases the collation results, while selecting the top screen 32c returns to the initial screen 30.

[0077] The present invention is not limited to the above embodiment, and modifications can be made within the scope of the claims. For example, the battery 8a of the control display unit 8 does not need to be used as a backup power source. In this case, turning on the SW6b supplies power from the battery 6c, while turning off the SW6b stops the power supply, eliminating the need for the USB port P1 in the power supply unit 6. Alternatively, by replacing the battery 6c from an alkaline battery with a lithium-ion battery, which is a secondary battery, and adding a charging port, the hassle of battery replacement can be eliminated. Furthermore, the present invention can be used not only for the lock rack of Non-Patent Document 3, but also for detecting residual cartridges of crushing agent of Non-Patent Document 4, which is a similar product.
