Description

Technical Field

[0001] The present invention relates to a technique for detecting unreacted remaining non-explosive crushing agents.

Background Art

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

[0003] Although such a crushing method using explosives is useful and economical, not only is a procedure for obtaining consumption permission required, but also in the case where there are houses in the urban area or in the vicinity, instantaneous high-level noise, ground vibration, etc. occur, and its use is greatly restricted.

[0004] Therefore, for the crushing of each of the above works in an environment with restrictive conditions such as vibration, the non-explosive crushing agent shown in Patent Document 2 is used. This non-explosive crushing agent instantaneously crushes by the expansion pressure due to the thermite reaction using a firing tool similar to an electric detonator, and unlike explosives, no shock wave is generated.

[0005] However, due to disconnection of wiring (leg wire) for supplying electric energy required for ignition, etc., a cartridge of unreacted remaining non-explosive crushing agent (hereinafter referred to as a remaining cartridge) may occur.

[0006] As a method for confirming the remaining cartridge, (1) As shown in FIG. 18, a method of confirming the presence of the wiring (leg wire) 102 of the cartridge 100 of the non-explosive crushing agent and manually operating the wiring 102, (2) As shown in FIG. 19, a method of attaching a fluorescent nylon cord 103 at the time of installing the cartridge 100 and manually operating the nylon cord 103 is known.

[Modes for carrying out the invention]

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

[0017] This non-explosive crushing agent is used for crushing in environments with constraints such as vibration, and examples include Rockrack (registered trademark) described in Non-Patent Document 3. Although this non-explosive crushing agent uses an ignition device similar to explosives, it crushes instantaneously due to the expansion pressure caused by the thermite reaction, and unlike explosives, it does not generate shock waves.

[0018] Specifically, the crushing process of the aforementioned construction work is carried out according to the handling procedure for the non-explosive crushing agent. In this case, a cartridge 100 of the non-explosive crushing agent, to which an igniter is attached, is inserted into a borehole 106 (see Figures 18 and 19) of the target to be crushed, such as a rock mass, and a packing material 105 is embedded therein. After that, the igniter is ignited using a dedicated igniter to react with the cartridge 100.

[0019] However, as mentioned above, if the borehole in the rock or other material is buried when cartridge 100 reacts and the wiring 102 or nylon cord 103 is not exposed above ground, it is difficult to visually confirm the presence of residual cartridges. Therefore, the detection device is used to detect unreacted residual cartridges. [Examples]

[0020] In Figure 1, 1 shows an embodiment of the detection device. In this embodiment, the detection device 1 itself detects residual cartridges at the work site and notifies the worker of their presence.

[0021] The detection device 1 has an antenna disk 4, a transmitting / receiving unit 5, a power supply unit 6, and a holder 7 for the control display unit attached to a crank-shaped bent grip pole 2.

[0022] To explain in more detail, as shown in Figure 2, an antenna disc 4 is rotatably attached to the tip of the grip pole 2, and a transmitting / receiving unit 5 is attached in front of the antenna disc 4.

[0023] On the other hand, as shown in Figure 3, the holder 7 is attached to the crank portion 3 of the grip pole 2, and the power supply unit 6 is attached to the tip side of the crank portion 3. This power supply unit 6 is connected to the transmitting / receiving unit 5 so that power can be supplied and data can be transmitted and received, while the holder 7 is fitted with a control display unit 8 as shown in Figure 4.

[0024] The control display unit 8 is comprised of a portable computer, and can use, for example, the handheld terminal described in Non-Patent Document 1. After being mounted in the holder 7, it is connected to the power supply unit 6 to perform the function of detecting and displaying the remaining cartridge.

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

[0026] In other words, each RFID tag 10 has its own unique numerical data (sequential number) recorded as unique information. In this embodiment, the remaining cartridge is detected by reading the unique information of the dedicated tag (RFID tag 10) using the RFID's automatic recognition function, i.e., radio waves.

[0027] The RFID tag 10 consists of a synthetic resin disc-type tag containing a long-wave band read-only IC chip and a circular coil, and is driven by the power induced in the circular coil by the alternating magnetic field generated by the antenna disk 4. At this time, it obtains a master clock from the alternating magnetic field and switches the modulation current on and off to return the unique information written during the manufacturing process to the antenna disk 4.

[0028] In this embodiment, the back surface of the RFID tag 10 is adhesive, and as shown in Figures 6(a) and 6(b), during the construction work, the adhesive surface is attached to the cartridge 100 of the non-explosive crushing agent. However, if the cartridge 100 ignites, the high heat generated will destroy the tag, 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 detected by the detection device 1. The detection device 1 mainly consists of an antenna disk 4, a transmitting / receiving unit 5, a power supply unit 6, a control display unit 8, and the registration device 11.

[0030] ≪Example of the structure of main sections 4-6, 8, and 11≫ Based on Figures 7 to 9, an example configuration of the antenna disk 4, transceiver unit 5, power supply unit 6, control table unit 8, and the registration device 11 will be explained. Here, the antenna disk 4 and the transceiver unit 5 are connected by a high-frequency coaxial cable, and as shown in Figure 7, RF (radio frequency) signals are transmitted between the two units 4 and 5.

[0031] The transmitting / receiving unit 5 and the power supply unit 6 are connected via a USB® cable, and the control display unit 8 is connected to the power supply unit 6 via the USB cable after being mounted in the holder 7. This allows DC power to be supplied from the power supply unit 6 to the transmitting / receiving unit 5 via the USB cable, and enables serial data communication between 5 and 8. At this time, the control display unit 8 can also be used as a backup power supply.

[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 shown in Figure 8, the unique information of the RFID tag 10 is transmitted and received between the two devices 8 and 11 via serial communication.

[0033] (1) Antenna disk 4 The antenna disk 4 includes a circular spiderweb coil, as shown in Figure 9, housed in a synthetic resin case. This circular spiderweb coil 4a is constructed by winding synthetic resin-coated copper wire 4c around an acrylic mold 4b.

[0034] Furthermore, the circular spiderweb coil 4a is tuned to longwave frequencies and generates an alternating magnetic field when it receives a longwave high-frequency signal (RF signal) from the transmitting / receiving unit 5.

[0035] Therefore, if an RFID tag 10 is present within the communication range (~60cm), the circular spiderweb coil 4a receives unique information from the RFID tag 10, which has been powered by the alternating magnetic field. As a result, the unique information of the RFID tag 10 is read, and a modulated wave (RF signal) containing the unique information of the RFID tag 10 is sent to the transmitting / receiving unit 5.

[0036] (2) Transmitter / receiver unit 5 As shown in Figure 7, the transmitting / receiving unit 5 includes an RFID reader (transmitting / receiving module) 5a, a serial data conversion circuit 5b, an antenna matching circuit 5c, a reading indicator LED / buzzer drive circuit 5d, a buzzer 5e, and an LED 5f.

[0037] Module 5a generates long-wave high-frequency signals to create an alternating magnetic field, while simultaneously outputting the unique information of the RFID tag 10 sent from the circular spiderweb coil 4a to the conversion circuit 5b in "ASCII" format. At the same time, it outputs an audible frequency detection signal to the drive circuit 5d, which causes the buzzer 5e to sound and the LED 5f to light up red.

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

[0039] The control display unit 8 receives this serial data, thereby receiving the unique information of the RFID tag 10 read by the circular spiderweb coil 4a of the antenna disk 4. 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 switching switch 6b, a battery (dry cell) 6c, a voltage monitoring circuit 6d, and an LED 6e. This battery 6c requires four alkaline dry cell batteries as the main power source to drive the detection device 1 and is housed in a battery case (not shown). The power supply unit 6 also has a USB port P1 for sending and receiving serial data with the control display unit 6, and a USB port P2 for using the control display unit 6 as a backup power source.

[0041] When SW6b is turned ON, the battery 6c is used as the power source, and a DC voltage is supplied to the transmitting / receiving unit 5 through the constant voltage circuit 6a. In this case, the green LED 6e mounted on the case of the power supply unit 6 lights up via the voltage monitoring circuit 6d. However, if the output voltage of the battery 6c falls below the specified voltage, the voltage monitoring circuit 6d turns off the green LED 6e to indicate power depletion.

[0042] On the other hand, when SW6b is turned OFF, no DC voltage is supplied from battery 6c to the transmitting / receiving unit 5. However, when the USB cable is connected to USB port P2, the battery 8a of the control display unit 8 is used as a backup power source, and DC voltage is supplied to the transmitting / receiving unit 5 by bypassing the constant voltage circuit 6a, causing the yellow LED 6e mounted on the case of the power supply unit 6 to light up. In this case, the voltage monitoring circuit 6d does not function, and the yellow LED 6e will not turn off even if the output voltage of battery 8a falls below the specified voltage.

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

[0044] The storage device (RAM, SSD, HDD, etc.) of the control display unit 8 has a table (not shown) for registering tag data. This table contains the unique information of the RFID tag 10 of each cartridge 100 used for crushing in the construction work, registered as tag data.

[0045] Normally, after the OS (Operation System) of the control display unit 8 starts up, a dedicated application for the detection device 1 is automatically launched. According to this dedicated application, (A) By referring to the tag data in the table, the unique information of each RFID tag 10 used in the construction can be confirmed. (B) By comparing the unique information of the RFID tag 10 read by the circular spiderweb coil 4a with the tag data registered in the table, residual cartridges can be detected.

[0046] (5) Tag data registration machine 11 As described above, the tag data registration device 11 is connected to the control display unit 8 by a USB cable when registering the unique information of the RFID tag, and as shown in Figure 8, it includes an antenna 12 and a transmitting / receiving unit 13.

[0047] Antenna 12 is configured in substantially the same way as antenna disk 4 and includes a circular spidernet coil 4a (see Figure 9) tuned to longwave frequencies, which generates an alternating magnetic field when it receives a longwave high-frequency signal from the transmitting / receiving unit 13.

[0048] Therefore, when the RFID tag 10 is held over the circular spiderweb coil 4a, the RFID tag 10, which has been powered by the alternating magnetic field, receives unique information and sends this unique information to the transmitting / receiving unit 13.

[0049] The transmitting / receiving unit 13 is configured in substantially the same way as the transmitting / receiving unit 5 (excluding the matching circuit 5c) and includes an RFID reader (transmitting / receiving module) 13a, a serial data conversion circuit 13b, a reading indicator LED / buzzer drive circuit 13c, a buzzer 13d, and an LED 13e.

[0050] The module 13a generates a long-wave high frequency to create an alternating magnetic field, while simultaneously outputting the unique information of the RFID tag 10 sent from the circular spiderweb coil 4a to the conversion circuit 13b in "ASCII" format. At the same time, it outputs an audible 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 by the module 13a. Here, it 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 control display unit 8 receives the serial data transmitted here, thereby receiving the unique information of the RFID tag 10 read by the circular spiderweb 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] Furthermore, the AC power supply 21 is converted to DC by the AC adapter 20, which then supplies power to the tag data registration device 11, and distributes it to each of the parts 13a to 13e.

[0054] ≪Procedure for detecting residual cartridges≫ The detection of residual cartridges by the detection device 1 is performed as follows: S01: Tag data registration S02: Attaching RFID tag 10 S03: Use of non-explosive crushing agent S04: Pre-preparation for detection S05: Searching for residual cartridges The procedure is carried out in the following steps. The details of each step (S01~S05) are explained below.

[0055] (1) Tag data registration (S01) When registering tag data to the control display unit 8, first power on the registration device 11 and connect it to the control display unit 8 using a USB cable, as shown in Figure 10.

[0056] Next, the power to the control display unit 8 is turned on, and the dedicated application is launched to display the initial screen 30 shown in Figure 14(a) on the monitor 8b (see Figure 12). Here, the registration screen 30a is selected from the initial screen 30 to transition to the registration screen 31 shown in Figure 14(b).

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

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

[0059] At this time, selecting Reset 31c on the registration screen 31 will cancel the tag data in the table. Alternatively, selecting the registration status confirmation screen 30b on the initial screen 30 will display and allow you to check the tag data in the table. After registering the tag data (S01), select the TOP screen 31d to return to the initial screen, select Exit 30d to close the dedicated application, and proceed to S02 and beyond.

[0060] (2) Attachment of RFID tag 10 (S02) When attaching the RFID tag 10, peel off the backing paper 10a beforehand and attach it to the upper end of the cartridge 100, as shown in Figures 11(a) and (b). At that time, it is preferable to reinforce it with tape (not shown) to prevent the RFID tag 10 from falling off during attachment.

[0061] (3) Use of non-explosive demolition agent (S03) The crushing process of the aforementioned construction work is carried out according to the handling procedure for the non-explosive crushing agent. That is, as described above, the cartridge 100 of the non-explosive crushing agent with an ignition device attached is inserted into the borehole 106 of the target to be crushed, such as a rock mass, taking care not to let the RFID tag 10 fall out. The packing material 105 is then embedded there. With the device in this state, the ignition device is ignited using a special igniter to react with cartridge 100.

[0062] (4) Preparations for detection (S04) When detecting residual cartridges, the following preparations are necessary: • Mounting and connection of the control display unit 8 (S04-1) • Activation of the detection device 1 (S04-2) • Activation of the control display unit 8 (S04-3) Perform the following task.

[0063] S04-1: The installation and connection procedure for the control display unit 8 will be explained based on Figure 12. Here, as shown in Figure 12(a), the control display unit 8, after tag data registration is complete, is attached to the holder 7. Then, as shown in Figure 12(b), the control display unit 8 and the USB port P2 of the power supply unit 6 are connected with a USB cable. When the battery 8a of the control display unit 8 is used as the power source, the USB port P1 is used on the power supply unit 6 side.

[0064] S04-2: The startup state of the detection device 1 will be explained based on Figure 13. In Figures 13(a) and 13(b), 6e-1 indicates a yellow LED 6e provided on the power supply unit 6, and 6e-2 indicates a green LED 6e provided on the power supply unit 6. Figure 13(a) shows the state in which LEDs 6e-1 and 6e-2 are not lit.

[0065] When the SW6b on the power supply unit 6 is turned ON, the LED6e-2 lights up as shown in Figure 13(b), power is supplied from the battery 6c to the transmitting / receiving unit 5, and the detection device 1 starts up. If the LED6e-2 does not light up even when the SW6b is turned ON, the dry cell battery in the battery 6c is depleted, so replace the dry cell battery.

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

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

[0068] (5) Exploration of residual cartridges (S05) The principle (exploration method) for detecting residual cartridges will be explained based on Figures 15 to 17. During the crushing process, as shown in Figure 15(a), a cartridge 100 with an ignition device attached is inserted into a borehole 106 of the rock or other object to be crushed, and a packing material 105 is embedded therein. In this state, the ignition device is ignited using a dedicated igniter to cause the cartridge 100 to react.

[0069] However, if the cartridge 100 remains without the ignition device being activated and without ignition, the RFID tag 10 attached to the upper surface of the cartridge 100 remains undamaged and in its original state, as shown in Figure 15(b).

[0070] At this time, the alternating magnetic field generated by the circular spiderweb coil 4a of the antenna disk 4 penetrates to a depth of about 40-50 cm into the ground directly below it (see 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 damaged, its unique information cannot be read, and the detection device 1 does not react.

[0071] On the other hand, as the detection device 1 is moved, if a residual cartridge is found directly beneath the range of the antenna disk 4, as shown in Figure 16(b), the RFID tag 10, which has been powered by the alternating magnetic field, will function and return 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 transmitting / receiving unit 5. At this time, as shown in Figure 17(b), the drive circuit 5d causes the LED 5f to light up red, and the buzzer 5e emits a 3.1KHz buzzer sound for about 1 second to inform the user that a residual cartridge has been detected. Note that Figure 17(a) shows the state where 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 spiderweb coil 4a of the antenna disk 4 via the transmitting / receiving 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 unique information of both matches as a result of the comparison, the matching unique information is displayed on the display unit 32a of the exploration screen 32 in Figure 14(c). This makes it possible for the user to understand that the cartridge 100 used in the construction remains as a residual cartridge in the rock mass or other object to be crushed.

[0075] As a result, by sequentially searching with the alternating magnetic field of the antenna disk 4, residual cartridges can be detected even if the wiring 102, nylon cord 103, etc., are cut while not exposed to the ground, or if they are buried by fragments.

[0076] Therefore, the detection device 1 makes it possible to detect residual cartridges regardless of the condition 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 results of the comparison, while selecting TOP screen 32c returns to the initial screen 30.

[0077] It should be noted that the present invention is not limited to the embodiments described above, and can be implemented with modifications within the scope of each claim. 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, when the SW6b is turned on, power is supplied from the battery 6c, and when the SW6b is turned off, the power supply is stopped, and the USB port P1 on the power supply unit 6 becomes unnecessary. Alternatively, replacing the alkaline batteries in the 6c with rechargeable lithium-ion batteries and adding a charging port would eliminate the hassle of changing batteries. Furthermore, the present invention can be used not only for the lock rack described in Non-Patent Document 3, but also for detecting residual cartridges of crushing agents as described in Non-Patent Document 4, as a similar product.
