Description

[Technical field]

[0001] The present invention relates to a portable recording system, and more particularly to a portable recording system that can be used when inspecting cracks in pipes or investigating the ecology of animals. [Background technology]

[0002] Patent Document 1 discloses a water leak detection system used at the site of a water leak inspection. This water leak detection system is composed of a water leak detector that measures vibrations at a measurement point such as the ground surface where pipes are buried, and an information terminal that presents the results of analyzing the vibration data measured by the water leak detector to the worker. A smartphone can be used as the information terminal, and it is said that the smartphone screen can display buttons labeled "simple measurement" and "take an image of the measurement point." [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Paragraphs (0011), (0014), (0016), (0016), (0043), (0051), and Figures 1 and 6 of JP 2023-001824 A Summary of the Invention [Problem to be solved by the invention]

[0004] Here, a user of the water leak detection system disclosed in Patent Document 1 typically operates the screen of their smartphone when starting, for example, a water pipe leak inspection, and taps a button labeled "Simple Measurement" that appears on the screen to start measurement.

[0005] Next, during the water pipe leak inspection, the user moves on foot while appropriately touching the leak detector's listening probe to the ground surface and measuring vibration data. If a measurement point suspected of having a leak is discovered based on the vibration data, the user again operates the smartphone screen and taps the button labeled "Take an image of measurement point" to capture an image of the site.

[0006] The water leak detection system disclosed in Patent Document 1 is configured to instruct imaging via the smartphone screen, and it is unclear from the description in Patent Document 1 whether the smartphone is held in the hand or in a pocket when vibration data is measured. In either case, however, it is believed that most users set their smartphones to sleep so that the screen is turned off when they are not using it as a user interface, and also set the screen to lock to prevent malfunctions and for security reasons.

[0007] If this is the case, the user will need to operate the smartphone screen, such as unlocking the screen and tapping a specific button, every time they start (and finish) a water pipe leak inspection or discover a measurement point where a leak is suspected. Such operations are troublesome for the user, and may even reduce the efficiency of the leak inspection.

[0008] Therefore, an object of the present invention is to improve the operability for the user when performing a water leak inspection or the like. [Means for solving the problem]

[0009] In order to solve the above problems, the portable recording system of the present invention comprises: A handheld type mobile terminal controller that outputs a recording processing instruction signal to a recording means of the mobile terminal; the portable terminal having the recording means for executing a recording process in accordance with an instruction signal output from the portable terminal controller; Equipped with.

[0011] The mobile terminal controller includes: a recording switch and a first resistor element which are connected in series with each other and are switched when the instruction signal for recording is output; a recording switch and a second resistor element which are connected in series with each other and are switched when the instruction signal for recording is output; are connected in parallel between the signal line transmitting each of the instruction signals and the ground line, The first resistor element and the second resistor element may have different resistance values.

[0012] The mobile terminal controller may also include a sound collection switch that is operated when issuing an instruction to collect sound to a sound collection device that collects an acoustic signal to be transmitted to the mobile terminal.

[0013] The mobile terminal controller includes: A sound collecting device is connected to the mobile terminal to collect the acoustic signal to be transmitted thereto; A sound collection switch that is operated when instructing the sound collection device to collect sound, and a power line for an amplifier that amplifies the acoustic signal; It can also be provided with:

[0014] The mobile terminal includes: The device may be a smartphone, a mobile phone, a PDA, a tablet device, or a notebook personal computer.

[0015] The mobile terminal includes: The portable terminal may also have an input terminal for inputting an instruction signal transmitted from the portable terminal controller.

[0016] Furthermore, the present invention relates to a controller for a portable terminal used in the portable recording system.

[0017] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In each drawing, the same parts are denoted by the same reference numerals.

[0018] Fig. 1 is a schematic diagram of a portable recording system according to an embodiment of the present invention. Fig. 1 shows a sound collection device 10, a portable terminal controller 20, a connecting device 30, a smartphone 40, a connection line 50, and a connection line 60, which will be described below. In this embodiment, the portable recording system will be described as being used as a water leakage inspection system.

[0019] The smartphone 40 can be connected to a server (not shown) that stores various data via a network such as the Internet. The smartphone 40 can also be connected, by wire or wirelessly, to headphones or earphones (not shown) that the user wears when working.

[0020] The sound collector 10 collects an acoustic signal to be output to a smartphone 40. The sound collector 10 corresponds to the "water leak detector" disclosed in Patent Document 1. However, the sound collector 10 differs from a water leak detector in that the sound collector 10 includes an amplifier 12 that amplifies the acoustic signal so that the acoustic signal (vibration data) is less affected by noise during transmission through the connection line 50.

[0021] The mobile terminal controller 20 outputs a recording process instruction signal (for example, a signal for switching between starting and ending recording) to the smartphone 40. The mobile terminal controller 20 is a handy type so that the user can operate it with one hand.

[0022] The mobile terminal controller 20 is equipped with, for example, a sound recording switch 22 located in a position operable by the user's thumb when outputting an instruction signal for recording, a video recording switch 24 located in a position operable by the user's thumb when outputting an instruction signal for recording, and a sound collection switch 26 located in a position operable by the user's index finger when instructing the sound collection device 10 to collect sound.

[0023] The connecting device 30 connects the mobile terminal controller 20 and the smartphone 40. The connecting device 30 corresponds to the "device main body" disclosed in Patent Document 1 in that the smartphone 40 is attached to the connecting device 30. However, the connecting device 30 differs from the device main body in that it does not include an amplifier that amplifies the acoustic signal (vibration data) or a power source for the sound collection device 10.

[0024] The coupling device 30 includes an attachment portion 31, a connection portion 32, a selector switch 33, an LED lamp 34, a USB Type-C terminal 35, an A / D converter 36, a signal processing portion 37, and a strap holder 38, which will be described below.

[0025] The mounting unit 31 is a portion to which the smartphone 40 is detachably mounted. Therefore, the mounting unit 31 allows the smartphone 40 to be entirely or partially replaced (for example, parts replacement such as battery replacement, display replacement, etc.).

[0026] The connection unit 32 is a portion to which the connection line 60 is connected. The connection unit 32 can be electrically connected to the smartphone 40, and is for supplying power to the sound collection device 10 using a battery of the smartphone 40 as a power source, and for supplying the smartphone 40 with an acoustic signal collected by the sound collection device 10 and / or various instruction signals.

[0027] The changeover switch 33 switches the on / off state of the portable recording system. When the changeover switch 33 is in the on state, power is supplied to the sound collection device 10, and when the changeover switch 33 is in the off state, the supply is stopped. However, the target of the on / off state switching may be, for example, a function of the portable recording system.

[0028] The LED lamp 34 is turned on when the changeover switch 33 is in the on state. The LED lamp 34 is not the main function of the portable recording system, but if the illuminance of the LED lamp 34 is varied according to the remaining battery power of the smartphone 40, the user can easily know the approximate charging time.

[0029] The USB Type-C terminal 35 is electrically connected to a USB Type-C terminal that the smartphone 40 itself has. When the smartphone 40 is attached to the connecting device 30, the USB Type-C terminal is blocked and cannot be used, but the USB Type-C terminal 35 can serve as a substitute. Therefore, for example, it is possible to charge the battery of the smartphone 40 through the USB Type-C terminal 35 without removing the smartphone 40 from the connecting device 30.

[0030] The A / D converter 36 converts the acoustic signal transmitted through the connection line 60 from an analog signal to a digital signal. Just to be clear, this acoustic signal is collected by the sound collection device 10, amplified by the amplifier means 12, and then input to the A / D converter 36 via the connection line 50, the mobile terminal controller 20, and the connection line 60.

[0031] The signal processor 37 outputs the acoustic signal converted by the A / D converter 36 to the smartphone 40 on condition that the sound collection switch 26 is on, but outputs it as is when the sound recording switch 22 or the video recording switch 24 is off, and outputs it after superimposing a corresponding instruction signal when it is on. Note that the signal processor 37 does not output the acoustic signal when the sound collection switch 26 is off.

[0032] The strap holder 38 is connected to a strap that enables the user to hang the connecting device 30 around the neck or shoulder. The strap holder 38 is not the main function of the portable recording system, but since the strap holder 38 is hung around the neck or the like only when necessary during work such as a water leakage test, it is only necessary to simply check the screen of the smartphone 40 attached to the connecting device 30.

[0033] The smartphone 40 is a mobile terminal that receives various signals output from the sound collection device 10 and the mobile terminal controller 20 via the connecting device 30 and processes the signals accordingly. As is well known, the smartphone 40 includes, for example, an imaging means 42 such as a camera, a sound collection means 44 such as a microphone, an instruction receiving / display means 46 such as a touch panel liquid crystal display, and a communication means 48 for connecting to a network.

[0034] The imaging means 42 can capture an image of a site where a water leak is suspected, as in Patent Document 1. The sound collection means 44 can input an acoustic signal collected by the sound collection device 10. The instruction reception / display means 46 can display the waveform of the input acoustic signal and a piping map of the inspection target, provide a viewfinder display when capturing an image with the imaging means 42, and receive instructions from the user. The communication means 48 can transmit and receive various data to and from a server, headphones, etc. (not shown).

[0035] The smartphone 40 is one aspect of a mobile terminal, and mobile terminals including mobile phones, PDAs, tablet terminals, and notebook personal computers that are equipped with the imaging means 42 and the like are also included in the mobile terminals referred to here.

[0036] The connection line 50 connects the sound collector 10 and the mobile terminal controller 20. The connection line 50 includes the signal line 27, the ground line 28, and the power line 29 described above. The connection line 50 may be provided with a grip like the "grip 22" in Patent Document 1. The connection part of the connection line 50 to the mobile terminal controller 20 may be detachable like the connection part 32, but is not limited to this. This makes it possible to replace only the desired parts as needed.

[0037] The connection line 60 connects the mobile terminal controller 20 and the coupling device 30. The connection line 60 also includes the signal line 27, the ground line 28, and the power line 29 described above.

[0038] Fig. 2 is a circuit diagram of the mobile terminal controller 20 shown in Fig. 1. The mobile terminal controller 20 includes a signal line 27 for transmitting each instruction signal, a ground line 28 connected to earth, and a power line 29 for supplying power to the sound collection device 10. For ease of understanding, Fig. 2 also includes connection lines 50 and 60 connected to the mobile terminal controller 20.

[0039] One end of the sound recording switch (element) 22, one end of the video recording switch (element) 24, and one end of the sound collecting switch (element) 26 are connected to a signal line 27 in parallel with one another.

[0040] The other end of the recording switch element 22 is connected to one end of the first resistor element 23, the other end of the video recording switch element 24 is connected to one end of the second resistor element 25, and the other end of the sound collection switch element 26 is connected to a first terminal of the amplification means 12.

[0041] The resistance values ​​of the first resistor element 23 and the second resistor element 25 are different by, for example, a factor of two. Therefore, when the audio recording switch element 22 is turned on and when the video recording switch element 24 is turned on, the level of the signal passing through the signal line 27 differs by, for example, a factor of two, and therefore the smartphone 40 can identify which button has been operated.

[0042] The other end of the first resistor element 23, the other end of the second resistor element 25, and the second terminal of the amplifier means 12 are connected in parallel to a ground line .

[0043] In the above, the present embodiment has been described with reference to a water leakage inspection system as an example of a portable recording system. It can also be used as an animal ecology research system. [Brief description of the drawings]
