A plurality of types of batteries 70 having different battery voltages can be attached to and detached from the battery mounting unit 40. The battery 70 includes a battery for a power tool and a dry battery pack. Further, the battery 70 may be a rechargeable battery.

In the present embodiment, the "battery voltage" is a value set to indicate the type of the battery 70. As such a battery voltage, for example, each value of "18V", "14.4V", and "10.3V" indicating the type of a battery for a power tool, and a dry battery pack capable of mounting eight AA batteries can be installed. A value of "12V" indicating the type of

The case where the battery can be attached to the battery will be described as an example (however, Ea> Eb). The types of batteries 70 that can be mounted on the battery mounting unit 40 are not limited to two types, and three or more types of batteries 70 may be mounted.

FIG. 3 is a perspective view showing an example of the battery mounting portion 40. As shown in FIG. 3, the battery mounting portion 40 has a guide portion 41 that guides the battery 70. The first battery 70A and the second battery 70B have a common configuration for mounting on the battery mounting unit 40. That is, the first battery 70A has a rail portion 71A guided by the guide portion 41. Further, the second battery 70B has a rail portion 71B guided by the guide portion 41. The rail portion 71A and the rail portion 71B can have, for example, the same shape and dimensions. With this configuration, the first battery 70A or the second battery 70B is mounted on the battery by sliding the rail portion 71A of the first battery 70A or the rail portion 71B of the second battery 70B along the guide portion 41 of the battery mounting portion 40. It is removable to the part 40.

The battery mounting unit 40 is electrically connected to the battery 70 by mounting the battery 70 of either the first battery 70A or the second battery 70B. That is, when the battery 70 is mounted on the battery mounting unit 40, power can be supplied from the battery 70 to the buried object exploration device 100 including the detection unit 20 via the battery mounting unit 40. Further, when the battery 70 is mounted on the battery mounting unit 40, a voltage signal indicating the voltage of the battery 70 can be supplied to the control unit 60 via the battery mounting unit 40. That is, in the present embodiment, for example, when the battery 70 is mounted on the battery mounting portion 40 and the power is turned on by the power button 31, power is supplied from the battery 70 to the buried object exploration device 100 to obtain a voltage. The signal is supplied to the control unit 60. In the following description, when referring to the battery 70 mounted on the battery mounting unit 40, it is referred to as "mounted battery 70".

The display unit 50 shown in FIGS. 1 and 2 displays image information. The display unit 50 displays, for example, the detection result of the detection unit 20. In addition, the display unit 50 displays setting information for making various settings of the buried object exploration device 100. As the display unit 50, various displays such as a liquid crystal display and an organic EL display can be applied. The display unit 50 may be a touch panel provided with a touch sensor. In this case, the touch panel has a configuration in which the operation unit 30 and the display unit 50 are combined.

The control unit 60 comprehensively controls the buried object exploration device 100. The control unit 60 includes a processing device including a CPU (Central Processing Unit) and a storage device including a RAM (Random Access Memory) or a ROM (Read Only Memory). The control unit 60 is arranged, for example, in the internal space of the housing 10.

The control unit 60 can control under the control conditions according to the mounted battery 70 mounted on the battery mounting unit 40 among the plurality of types of batteries 70. For example, in the present embodiment, the user sets in advance information about the battery voltage of the mounted battery 70, and the control unit 60 controls under the control conditions according to the set information. Therefore, when the user makes the setting according to the mounted battery 70, the control unit 60 can control under the control conditions according to the mounted battery 70. The control unit 60 includes an input unit 61, an output unit 62, a processing unit 63, and a storage unit 64. The input unit 61 acquires an input signal. The input signal acquired by the input unit 61 includes, for example, a detection signal from the detection unit 20, an operation signal from the operation unit 30, a voltage signal indicating the voltage of the mounted battery 70, and the like. The voltage supplied from the mounted battery 70 is reduced to a predetermined voltage by, for example, a pressure reducing circuit (not shown). In this case, the predetermined voltage is set to a value lower than, for example, the battery voltage of the battery 70 that can be mounted on the battery mounting unit 40. The output unit 62 outputs a control signal from the processing unit 63. The voltage supplied from the mounted battery 70 may be boosted and supplied.

The processing unit 63 performs various processes based on, for example, information included in an input signal input to the input unit 61, information stored in the storage unit 64, and the like. The processing unit 63 includes a detection control unit 63a, a display control unit 63d, an end operation control unit 63c, and a battery setting control unit 63b.

The detection control unit 63a controls the detection operation in the detection unit 20. The detection control unit 63a can perform the same control of the detection operation regardless of the type of the mounted battery 70. The battery setting control unit 63b makes settings related to the battery voltage of the mounted battery 70. The battery setting control unit 63b sets the battery voltage of the mounted battery 70 based on the input result by the operation unit 30. In the present embodiment, the battery setting control unit 63b sets whether the mounted battery 70 is the first battery 70A or the second battery 70B based on the input result by the operation unit 30. Further, the battery setting control unit 63b sets, for example, an exchange threshold value (first threshold value) and an end threshold value (second threshold value) for the voltage of the mounted battery 70 based on the set battery voltage of the mounted battery 70. In the present embodiment, the battery setting control unit 63b has a replacement threshold value and an end threshold value for the voltage of the mounted battery 70 based on whether the set mounted battery 70 is the first battery 70A or the second battery 70B. To set. Hereinafter, the voltage, replacement threshold value, and termination threshold value of the mounted battery 70 will be described.

FIG. 4 is a graph schematically showing an example of the relationship between the voltage of the first battery 70A and the second battery 70B and the remaining capacity. In FIG. 4, the remaining capacity (unit: the unit is) the value obtained by dividing the capacity of the batteries (first battery 70A, second battery 70B) at a certain time point by the fully charged capacity of the battery at a certain time point and multiplying by 100. %).

As shown in FIG. 4, when the remaining capacity is 100%, the voltage of the first battery 70A and the voltage of the second battery 70B are higher than the voltage Ea and the voltage Eb corresponding to the battery voltage, respectively. There is. Discharge is performed from this state, and as the discharge capacity increases, the voltages of the first battery 70A and the second battery 70B gradually decrease, and become lower than the values of the voltages Ea and Eb, respectively. When further discharging is performed, for example, the voltage gradually decreases until the discharge capacity reaches a predetermined value, but when the discharge capacity exceeds the predetermined value, the voltage drops sharply and reaches the final voltage. In order to protect the battery, the end threshold value E3 is set when the voltage of the first battery 70A and the voltage of the second battery 70B are higher than the end voltage, and when the end threshold value E3 is reached, the end operation of the buried object exploration device 100 is performed. Do. The exchange thresholds E1 and E2 are set in order to prevent the end operation from being suddenly started.

The exchange threshold values E1 and E2 are threshold values set to guide the user to replace the battery. When the voltage drops to the exchange thresholds E1 and E2, respectively, due to the discharge of the first battery 70A and the second battery 70B, the user is instructed to replace the battery. The replacement threshold is set for each type of battery 70. In other words, the replacement threshold is set for each battery voltage. The exchange threshold values E1 and E2, and the guidance information can be stored in the storage unit 64.

The end threshold value E3 is a threshold value set for performing the end operation of the buried object exploration device 100. That is, when the voltage drops to the end threshold value E3 due to the discharge of the first battery 70A and the second battery 70B, the end operation control unit 63c performs the end operation of the buried object exploration device 100. The end threshold value E3 can be stored in the storage unit 64. The end threshold value E3 is set to a value at which the voltages of the first battery 70A and the second battery 70B do not drop to the end voltage even when the end operation of the buried object exploration device 100 is performed. The end threshold value E3 may be set to a value common to a plurality of types of batteries.

In the present embodiment, for the first battery 70A, an exchange threshold value E1 and an end threshold value E3 are set between the fully charged voltage value and the final voltage value. Further, for the second battery 70B, an exchange threshold value E2 and an end threshold value E3 are set between the fully charged voltage value and the end voltage value.

When the mounted battery 70 is set to the first battery 70A, the battery setting control unit 63b sets the replacement threshold value to the replacement threshold value E1 (first mode) set for the first battery 70A. Further, when the mounted battery 70 is set to the second battery 70B, the battery setting control unit 63b sets the replacement threshold value to the replacement threshold value E2 (second mode) set for the second battery 70B. As described above, in the present embodiment, the type of the battery 70, that is, the replacement threshold value corresponding to the battery voltage is preset as the control condition. The control unit 60 controls under the control conditions according to the type of the mounted battery 70.

The end operation control unit 63c controls the end operation of the buried object exploration device 100. The end operation control unit 63c causes a predetermined end operation to be performed when the power button 31 is pressed while the power of the buried object exploration device 100 is on. Further, the end operation control unit 63c causes the end operation to be performed when the voltage of the mounted battery 70 becomes equal to or less than the above end threshold value.

The display control unit 63d controls the display operation of the display unit 50. The display control unit 63d can display the detection result of the detection unit 20 on the display unit 50. Further, the display control unit 63d can set a setting screen for setting the mounted battery 70 on the display unit 50. In this case, various information included in the setting screen can be stored in the storage unit 64.

FIG. 5 is a diagram showing an example of the contents displayed on the display unit 50. In FIG. 5, a case where the mounted battery 70 is set to be the first battery 70A or the second battery 70B is shown as an example. As shown in FIG. 5, the display control unit 63d arranges the first information C1 for selecting the first battery 70A and the second information C2 for selecting the second battery 70B on the display unit 50. It is displayed with. The first information C1 and the second information C2 each include information about the value of the battery voltage. Further, the display control unit 63d causes the display unit 50 to display a frame F surrounding one of the first information C1 and the second information C2. Of the first information C1 and the second information C2, the information enclosed in the frame F is the information currently selected. For example, when the movement buttons 33a and 33b of the operation unit 30 are pressed, the information selected by the frame F is switched between the first information C1 and the second information C2.

For example, when the decision button 34 of the operation unit 30 is pressed while the first information C1 is selected by the frame F, the battery setting control unit 63b sets that the mounted battery 70 is the first battery 70A. .. That is, the battery setting control unit 63b sets the exchange threshold value to the first mode (exchange threshold value E1).

Further, when the decision button 34 of the operation unit 30 is pressed while the second information C2 is selected by the frame F, the battery setting control unit 63b sets that the mounted battery 70 is the second battery 70B. .. That is, the battery setting control unit 63b sets the exchange threshold value to the second mode (exchange threshold value E2).

The display control unit 63d causes the display unit 50 to display guidance information for guiding the battery to be replaced when the voltage of the mounted battery 70 becomes equal to or lower than the above exchange threshold values E1 and E2. FIG. 6 is a diagram showing another example of the content displayed on the display unit 50. As shown in FIG. 6, the display control unit 63d can display the guidance information I1 to guide the replacement of the battery 70 on the display unit 50 when the voltage of the mounted battery 70 drops to the replacement threshold value. For example, when the exchange threshold value E1 of the first mode is set as the exchange threshold value, the display control unit 63d causes the display unit to display the guidance information I1 when the voltage of the mounted battery 70 drops to the exchange threshold value E1. Further, when the exchange threshold value E2 of the second mode is set as the exchange threshold value, the display control unit 63d causes the display unit to display the guidance information I1 when the voltage of the mounted battery 70 drops to the exchange threshold value E2. .. FIG. 6 shows an example in which the guide information I1 is arranged in the central portion of the display unit 50, but the present invention is not limited to this. The guidance information I1 may be arranged on the peripheral edge of the display unit 50.

The display control unit 63d can display the information on the battery voltage of the mounted battery 70 on the display unit 50 together with the information for guiding the mounted battery 70 to be replaced. That is, the display control unit 63d can display the battery voltage (type) of the mounted battery 70 and the battery replacement guide in association with each other on the display unit 50. FIG. 7 is a diagram showing another example of the content displayed on the display unit 50. In FIG. 7, a case where the exchange threshold value E2 of the second mode is set will be described as an example. When the voltage of the mounted battery 70 drops to the replacement threshold value E2 of the second battery 70B, the display control unit 63d replaces the battery when the mounted battery 70 is the second battery 70B, as shown in FIG. The guidance information I2 to be guided can be displayed on the display unit 50. Similarly, when the exchange threshold value E1 of the first mode is set, when the voltage of the mounted battery 70 drops to the exchange threshold value E1 of the first battery 70A, the same guidance information is displayed on the display unit 50. It is possible. That is, the display control unit 63d can display on the display unit 50 guidance information for guiding the battery to be replaced when the mounted battery 70 is the first battery 70A.

In this way, by setting whether the mounted battery 70 is the first battery 70A or the second battery 70B and setting the replacement threshold value according to the setting result, the guidance information is displayed at an appropriate timing. ..

FIG. 8 is a diagram showing another example of the content displayed on the display unit 50. As shown in FIG. 8, when the voltage of the mounted battery 70 drops to the end threshold value E3, the display control unit 63d displays guidance information I3 to guide the battery to be replaced after the end operation is performed. It can be displayed at 50. The display control unit 63d causes the display unit 50 to display the guidance information I3 before the end operation by the end operation control unit 63c is performed. In this case, the end threshold value of the battery 70 is set to a value that enables the display unit 50 to display the guidance information I3.

Further, the battery setting control unit 63b can set the exchange threshold value E1 of the first mode as the exchange threshold value when no input is performed in the operation unit 30, that is, the default exchange threshold value. As a result, for example, when the mounted battery 70 is the second battery 70B, the guidance information is displayed at a timing that is too early as compared with the case of the second mode. Therefore, the user can be made aware at an early stage that the type of the mounted battery 70 (second battery 70B) and the setting in the buried object exploration device 100 are different.

FIG. 9 is a flowchart showing the operation flow of the buried object exploration device 100. The operation of the buried object exploration device 100 is performed under the control of the control unit 60. When the first battery 70A or the second battery 70B is attached to the battery mounting unit 40 of the buried object exploration device 100 and the power button 31 of the operation unit 30 is pressed, the control unit 60 starts up the buried object exploration device 100. I do. After the startup process is completed, the display control unit 63d of the control unit 60 causes the display unit 50 to display information for setting whether the mounted battery 70 is the first battery 70A or the second battery 70B. , The user is made to select the battery voltage of the mounted battery 70 (step S10).

When the battery voltage of the mounted battery 70 is selected, the battery setting control unit 63b sets the mode of the replacement threshold value of the battery 70 to the first mode or the second mode according to the selection (step S20). That is, when the mounted battery 70 is set to be the first battery 70A, the battery setting control unit 63b sets the replacement threshold value to the replacement threshold value E1 in the first mode. When the mounted battery 70 is set to be the second battery 70B, the battery setting control unit 63b sets the replacement threshold value to the replacement threshold value E2 in the second mode.

After the replacement threshold is set, the display control unit 63d detects whether or not the voltage of the mounted battery 70 is equal to or lower than the replacement threshold (step S30). When the display control unit 63d detects in step S30 that the voltage of the mounted battery 70 is larger than the replacement threshold value (No in step S30), the display control unit 63d causes the display control unit 63d to repeatedly perform the operation of step S30. On the other hand, when the display control unit 63d detects in step S30 that the voltage of the mounted battery 70 is equal to or lower than the replacement threshold value (Yes in step S30), the display control unit 63d guides the mounted battery 70 to be replaced. The guidance information to be displayed is displayed on the display unit 50 (step S40).

After that, the display control unit 63d detects whether or not the voltage of the mounted battery 70 is equal to or lower than the end threshold value (step S50). When the display control unit 63d detects in step S40 that the voltage of the mounted battery 70 is larger than the end threshold value (No in step S50), the display control unit 63d causes the display control unit 63d to repeatedly perform the operation of step S50. On the other hand, when the display control unit 63d detects in step S30 that the voltage of the mounted battery 70 is equal to or lower than the end threshold value (Yes in step S50), the display control unit 63d performs the end operation of the buried object exploration device 100. Let it be done (step S60). Prior to step S60, the display control unit 63d may display guidance information to guide the display unit 50 to replace the mounted battery 70 after the end operation is performed.

As described above, the buried object exploration device 100 according to the present embodiment can be equipped with a detection unit 20 for detecting a buried object buried in a predetermined object and a plurality of types of batteries 70 having different battery voltages. Control is performed under control conditions according to the battery mounting unit 40 capable of supplying power to at least the detection unit 20 with the battery 70 mounted, and the mounted battery 70 mounted on the battery mounting unit 40 among a plurality of types of batteries 70. A control unit 60 for performing the operation is provided.

FIG. 33 is a graph schematically showing another example of the relationship between the voltage and the remaining capacity of the first battery 70A and the second battery 70B. As shown in FIG. 33, the end threshold value E4 is set for the first battery 70A, and the end threshold value E5 is set for the second battery 70B. In the example shown in FIG. 33, the end threshold value E4 of the first battery 70A is higher than the replacement threshold value E2 of the second battery 70B, but the present invention is not limited to this. For example, the end threshold value E4 of the first battery 70A may be equal to or less than the replacement threshold value E2 of the second battery 70B.

For example, when the mounted battery 70 is set to the first battery 70A and the voltage of the mounted battery 70 drops to the end threshold value E4, the end operation control unit 63c performs the end operation of the buried object exploration device 100. Further, for example, when the mounted battery 70 is set to the second battery 70B and the voltage of the mounted battery 70 drops to the end threshold value E5, the end operation control unit 63c performs the end operation of the buried object exploration device 100.
