Description
Integrated control system for electrical construction tools
[0001] The present invention relates to a system for performing integrated control of a plurality of electrical construction tools.
[0002] Patent Document 1 describes a submersible pump device that includes a first submersible pump and a second submersible pump.
[0003] The submersible pump device of Patent Document 1 detects the level of sewage and switches between two operating modes: a mode in which only the first submersible pump operates, and a mode in which the first submersible pump and the second submersible pump operate in parallel.
[0004] JP 2018-168790 A
[0005] However, in the conventional device shown in Patent Document 1, the input voltage of the underwater voltage must be set, and the first and second submersible pumps must have exactly the same specifications, which makes them difficult to use. This is not limited to submersible pumps, but applies to other general electrical tools used in construction work as well.
[0006] Therefore, an object of the present invention is to optimally drive a plurality of electrical work tools in accordance with the desired driving conditions without restricting the selection of the electrical work tools.
[0007] An integrated control system for electrical tools for construction work according to an embodiment of the present invention includes a plurality of electrical tools for construction work and a connection control member. Each of the electrical tools for construction work is provided with a power plug. The connection control member is connected between a power source and the plurality of power plugs provided on the electrical tools for construction work and individually controls electrical connection and disconnection between the power source and each of the plurality of power plugs.
[0008] The connection control member includes a sensor and a communication unit. The sensor detects the power consumption values of the multiple electrical construction tools individually. The communication unit transmits the detected power consumption values to an external device and receives a control signal from the external device that activates or deactivates the electrical construction tools based on the power consumption values. The connection control member controls electrical conduction and electrical interruption between the power source and the multiple power plugs based on the control signal.
[0009] In this configuration, the power supply to the multiple electrical tools is controlled based on the power consumption value detected by the connection control component (a specific example is a multi-power tap). This makes it possible to appropriately operate the multiple electrical tools according to their operating status, regardless of their specifications.
[0010] According to this invention, it is possible to optimally drive a plurality of electrical work tools in accordance with the conditions under which they are to be driven, without restricting the selection of the electrical work tools.

[0012] First Embodiment An integrated control system for electrical tools for construction work according to a first embodiment of the present invention will be described with reference to the drawings.
[0013] 1 is a block diagram showing an example of the configuration of an integrated control system for construction tools according to a first embodiment of the present invention. As shown in FIG. 1, the integrated control system 1 for construction tools (hereinafter referred to as the integrated control system) includes a multi-power strip 10, multiple pumps 81-84, a control terminal 920, and a server device 930.
[0014] The multi-power tap 10 corresponds to the "connection control member" of the present invention. The plurality of pumps 81-84 correspond to the "electrical construction tools" of the present invention. Note that the number of pumps, i.e., the number of electrical construction tools, is not limited to four, as long as it is plural.
[0015] The electrical tools for construction are not limited to pumps, but may be, for example, water treatment equipment, lighting equipment, cleaning equipment, power tools for cutting, polishing, or processing, or portable air conditioning equipment. Furthermore, the electrical tools for construction are electrical tools used at the construction site 91, and in particular, electrical tools used temporarily at the construction site 91. In other words, the main target of the electrical tools for construction in this embodiment is electrical tools used temporarily by rental, lease, or the like.
[0016] A plurality of pumps 81-84 and a multi-power tap 10 are placed at a construction site 91. The pump 81 has a power plug 810. The pump 82 has a power plug 820. The pump 83 has a power plug 830. The pump 84 has a power plug 840.
[0017] The multi-power tap 10 includes a plurality of power jacks 11-14, a power wiring 101, and a power plug 102. The plurality of power jacks 11-14 are connected to the power plug 102 via the power wiring 101, as will be described in detail later.
[0018] A power plug 810 of a pump 81 is connected to power jack 11 of the multi-power tap 10. A power plug 820 of a pump 82 is connected to power jack 12. A power plug 830 of a pump 83 is connected to power jack 13. A power plug 840 of a pump 84 is connected to power jack 14.
[0019] The power plug 102 of the multi-power tap 10 is connected to a power jack 910 that is connected to a commercial power source provided at the construction site 91 .
[0020] The multi-power tap 10 can individually switch between electrical continuity and electrical isolation between each of the multiple power jacks 11-14 and the power plug 102. This allows the multi-power tap 10 to individually switch between electrical continuity and electrical isolation between the power plug 810 of pump 81, the power plug 820 of pump 82, the power plug 830 of pump 83, and the power plug 840 of pump 84 and the commercial power supply.
[0021] The control terminal 920 may be, for example, a desktop PC placed in the management room 92, or may be a tablet PC carried by the manager. The management room 92 is located in a place different from the construction site 91. The server device 930 is located in a place different from the construction site 91.
[0022] The server device 930 may be located in a place different from the management room 92 or may be located in the management room 92 .
[0023] The multi-power tap 10, the control terminal 920, and the server device 930 each have a communication function, which enables data communication among the three. For example, the multi-power tap 10, the control terminal 920, and the server device 930 can communicate data via communication using the Internet, communication using a communication company's network, or direct wireless communication including short-range wireless communication.
[0024] In this configuration, the integrated control system 1 generally realizes the following control.
[0025] The multi-power tap 10 detects the power consumption value of each of the plurality of pumps 81-84 individually.
[0026] The multi-power tap 10 transmits the detected power consumption value to the server device 930 .
[0027] The control terminal 920 sets the conditions for operating or stopping each of the plurality of pumps 81 to 84 based on the power consumption value of each pump. This setting is performed, for example, at the construction site 91 before operating the plurality of pumps 81 to 84.
[0028] The control terminal 920 provides the set operation or stop conditions to the server device 930. The server device 930 stores the operation or stop conditions.
[0029] The server device 930 determines whether to operate or stop the plurality of pumps 81-84 based on the power consumption value and the operation or stop conditions received from the multi-power tap 10.
[0030] The server device 930 generates a control signal based on the determined information on whether the pumps 81 to 84 are operating or stopped, and transmits the control signal to the multi-power tap 10.
[0031] Based on the received control signal, the multi-power tap 10 controls electrical conduction and electrical disconnection between the commercial power source and the power plug 810 of pump 81, the power plug 820 of pump 82, the power plug 830 of pump 83, and the power plug 840 of pump 84.
[0032] For example, a case will be described in which the control signal instructs that only pump 81 be operated and that multiple pumps 82 to 84 be stopped. Based on this control signal, multi-power tap 10 electrically connects the commercial power source to power plug 810 of pump 81, and electrically disconnects the commercial power source from power plug 820 of pump 82, the commercial power source from power plug 830 of pump 83, and the power plug 840 of pump 84.
[0033] This eliminates the need for the integrated control system 1 to directly acquire the load status from the multiple pumps 81-84 (electrical construction tools). Therefore, for example, it is possible to select multiple pumps 81-84 that do not have a function for monitoring the load status. Furthermore, if the load characteristics of the multiple pumps 81-84 (electrical construction tools) are known in advance, there is no need to completely standardize the specifications of each pump.
[0034] Therefore, the integrated control system 1 can optimally drive the multiple pumps 81-84 (electrical construction tools) according to the conditions under which they are to be driven, without restricting the selection of the multiple pumps 81-84 (electrical construction tools).
[0035] In order to achieve the above-described effects, the multi-power tap 10 has, for example, the following configuration: Fig. 2 is an equivalent circuit diagram showing an example of the configuration of the multi-power tap according to the first embodiment of the present invention.
[0036] As shown in FIG. 2, the multi-power tap 10 includes a first smart plug SP1, a second smart plug SP2, a third smart plug SP3, and a fourth smart plug SP4, a power line 101, and a power plug 102.
[0037] The first smart plug SP1, the second smart plug SP2, the third smart plug SP3, and the fourth smart plug SP4 and a portion of the power supply wiring 101 are housed in the housing 100. The other portion of the power supply wiring 101 and the power supply plug 102 are disposed outside the housing 100. The power supply wiring 101 is composed of a pair of wiring, a first power supply wiring 1011 and a second power supply wiring 1012.
[0038] The first smart plug SP1 includes a power jack 11, an AC-DC converter 210, a microcomputer 211, a current detection circuit 212, a voltage detection resistor 213, a communication unit 214, an antenna 215, a relay switch 31, a power supply wiring 111, and a power supply wiring 112. The power supply wiring 111 is connected to the first power supply wiring 1011, and the power supply wiring 112 is connected to the second power supply wiring 1012. The current detection circuit 212 and the voltage detection resistor 213 correspond to the "sensor" of the present invention.
[0039] The second smart plug SP2 includes a power jack 12, an AC-DC converter 220, a microcomputer 221, a current detection circuit 222, a voltage detection resistor 223, a communication unit 224, an antenna 225, a relay switch 32, a power supply wiring 121, and a power supply wiring 122. The power supply wiring 121 is connected to the first power supply wiring 1011, and the power supply wiring 122 is connected to the second power supply wiring 1012. The current detection circuit 222 and the voltage detection resistor 223 correspond to the "sensor" of the present invention.
[0040] The third smart plug SP3 includes a power jack 13, an AC-DC converter 230, a microcomputer 231, a current detection circuit 232, a voltage detection resistor 233, a communication unit 234, an antenna 235, a relay switch 33, a power supply wiring 131, and a power supply wiring 132. The power supply wiring 131 is connected to the first power supply wiring 1011, and the power supply wiring 132 is connected to the second power supply wiring 1012. The current detection circuit 232 and the voltage detection resistor 233 correspond to the "sensor" of the present invention.
[0041] The fourth smart plug SP4 includes a power jack 14, an AC-DC converter 240, a microcomputer 241, a current detection circuit 242, a voltage detection resistor 243, a communication unit 244, an antenna 245, a relay switch 34, a power supply wiring 141, and a power supply wiring 142. The power supply wiring 141 is connected to the first power supply wiring 1011, and the power supply wiring 142 is connected to the second power supply wiring 1012. The current detection circuit 242 and the voltage detection resistor 243 correspond to the "sensor" of the present invention.
[0042] The first smart plug SP1, the second smart plug SP2, the third smart plug SP3, and the fourth smart plug SP4 have the same circuit element connection configuration. Therefore, the circuit element connection configuration will be described using the first smart plug SP1 as an example, and descriptions of the second smart plug SP2, the third smart plug SP3, and the fourth smart plug SP4 will be omitted.
[0043] The relay switch 31 is inserted (connected in series) into the power supply wiring 112 .
[0044] The AC-DC converter 210 has an AC side terminal and a DC side terminal. The AC side terminal is connected to the power supply wiring 111. The DC side terminal is connected to the microcomputer 211 and the communication unit 214. Although not shown, the power supply terminal of the operational amplifier of the current detection circuit 212 is also connected to a DC type terminal. As a result, the AC-DC converter 210 supplies DC power for driving the microcomputer 211, the communication unit 214, and the operational amplifier of the current detection circuit 212.
[0045] The current detection circuit 212 includes a current detection resistor and an operational amplifier. The current detection resistor is inserted (connected in series) into the power supply wiring 112. More specifically, the current detection resistor is connected closer to the second power supply wiring 1012 than the position where the relay switch 31 is inserted into the power supply wiring 112. Input terminals of the operational amplifier are connected to both ends of the current detection resistor, and the output terminal of the operational amplifier is connected to the microcomputer 211.
[0046] One end of the voltage detection resistor 213 is connected to the power supply wiring 111. The other end of the voltage detection resistor 213 is connected to the microcomputer 211.
[0047] A data output terminal of the microcomputer 211 is connected to the communication unit 214. A relay control signal output terminal of the microcomputer 211 is connected to the relay switch 31. An antenna 215 is connected to the communication unit 214.
[0048] With this configuration, the first smart plug SP1 operates, for example, as follows.
[0049] When the power plug 810 of the pump 81 is inserted into the power jack 11, the pump 81 is in the on state, and the relay switch 31 is in the conductive state, the current detection circuit 212 generates an output voltage corresponding to the current flowing through the power jack 11.
[0050] The microcomputer 211 detects the current consumption value of the pump 81 connected to the power jack 11 from the output voltage of the current detection circuit 212. In addition, a voltage detection resistor 213 is connected to the microcomputer 211, and the applied voltage value of the pump 81 connected to the power jack 11 is detected from the potential of the voltage detection resistor 213.
[0051] The microcomputer 211 detects the current consumption value and the applied voltage value at a predetermined sampling period, and outputs the detected values as power consumption information to the communication unit 214. The communication unit 214 transmits the power consumption information to the server device 930 via the antenna 215.
[0052] For example, if the rated voltage of the pump 81 is always constant, the power consumption information only needs to include the current consumption value. However, it is preferable that the power consumption information include both the current consumption value and the applied voltage value.
[0053] When the microcomputer 211 receives the control signal for electrical continuity from the server device 930, it controls the relay switch 31 to a conductive state, thereby supplying power to the pump 81 from the commercial power source.
[0054] When the microcomputer 211 receives the control signal for electrical disconnection from the server device 930, it controls the relay switch 31 to the disconnected state (open state), thereby cutting off the power supply to the pump 81.
[0055] The second smart plug SP2, the third smart plug SP3, and the fourth smart plug SP4 are controlled in the same manner as the first smart plug SP1.
[0056] In general, the second smart plug SP2 detects the current consumption value and applied voltage value of the pump 82 connected to the power jack 12, generates power consumption information of the pump 82, and transmits it to the server device 930. When the second smart plug SP2 receives an electrical conduction control signal from the server device 930, it controls the relay switch 32 to a conductive state. When the second smart plug SP2 receives an electrical interruption control signal from the server device 930, it controls the relay switch 32 to an interruption state (open state). This controls the supply of power from the commercial power source to the pump 82 and the interruption of the power supply to the pump 82.
[0057] The third smart plug SP3 detects the current consumption value and applied voltage value of the pump 83 connected to the power jack 13, generates power consumption information of the pump 83, and transmits it to the server device 930. When the third smart plug SP3 receives an electrical conduction control signal from the server device 930, it controls the relay switch 33 to a conductive state. When the third smart plug SP3 receives an electrical interruption control signal from the server device 930, it controls the relay switch 33 to a cutoff state (open state). This controls the supply of power from the commercial power source to the pump 83 and the interruption of the power supply to the pump 83.
[0058] The fourth smart plug SP4 detects the current consumption value and applied voltage value of the pump 84 connected to the power jack 14, generates power consumption information of the pump 84, and transmits it to the server device 930. When the fourth smart plug SP4 receives an electrical conduction control signal from the server device 930, it controls the relay switch 34 to a conductive state. When the fourth smart plug SP4 receives an electrical interruption control signal from the server device 930, it controls the relay switch 34 to a cutoff state (open state). This controls the supply of power from the commercial power source to the pump 84 and the interruption of the power supply to the pump 84.
[0059] Such an integrated control system 1 is used, for example, in the following environment.
[0060] Fig. 3 is a diagram showing an example of a usage environment of the integrated control system according to the first embodiment of the present invention. As shown in Fig. 3, the integrated control system 1 is used at a building construction site. The building corresponds to the construction site 91, and a building away from the building corresponds to the management office 92. Although not shown in the figure, the server device 930 is located in a different location.
[0061] The top of the building under construction has no roof. Therefore, when it rains, water accumulates at the top. This water interferes with the construction work, so drainage is necessary.
[0062] Therefore, multiple pumps 81-84 are placed at the top where water tends to accumulate, and the accumulated water is drained appropriately. In this case, the number of pumps required varies depending on the state of the water pool, how the water accumulates, and the drainage capacity of the pump, and there is an appropriate number of pumps in operation.
[0063] The integrated control system 1 is effective when discharging water by operating an appropriate number of pumps 81-84 in this manner.
[0064] Figure 4 is a graph showing an example of the relationship between rain conditions, puddle water levels, and the operating status of multiple pumps. Rain conditions can be classified into light rain and heavy rain. In Figure 4, light hatching indicates periods of light rain, and dark hatching indicates periods of heavy rain.
[0065] The pumps 81-84 are always powered on so that they operate when power is supplied. The pumps 81-84 can control their operating state according to the load. Specifically, the pumps 81-84 can achieve intermittent power consumption, increasing the duty ratio of their on-time when the load is high and decreasing the duty ratio of their on-time when the load is low.
[0066] As shown in the period PRD1 in Figure 4, during light rain, accumulated water can be drained by normal operation of only the pump 81. In this case, the first smart plug SP1 provides waveforms of applied voltage values and consumed current values corresponding to normal operation of the pump 81. The first smart plug SP1 generates a time characteristic of power consumption from the time characteristics of the applied voltage values and consumed current values, and transmits this to the server device 930 as power consumption information.
[0067] The server device 930 receives the power consumption information and detects from pre-stored conditions that the pump 81 is operating normally. Since the pump 81 is operating stably in normal operation, the server device 930 determines that the pump 81 should continue to operate as is and that there is no need to operate the other pumps 82-84.
[0068] Based on the result of this determination, the server device 930 transmits a control signal for electrical continuity to the first smart plug SP1.
[0069] The first smart plug SP1 receives the control signal for electrical conduction and maintains the relay switch 31 in a conductive state.
[0070] Next, as shown in period PRD2 in Figure 4, when light rain changes to heavy rain, the accumulated water cannot be drained by normal operation of only the pump 81 (water level rises). In this case, the first smart plug SP1 obtains waveforms of applied voltage values and consumed current values corresponding to overload operation of the pump 81. The first smart plug SP1 generates a time characteristic of power consumption from the time characteristics of the applied voltage values and consumed current values, and transmits this to the server device 930 as power consumption information.
[0071] The server device 930 receives the power consumption information and detects from pre-stored conditions that the pump 81 is being driven under overload. In order to reduce the load on the pump 81, the server device 930 determines to maintain the driving of the pump 81 and also drive the pump 82.
[0072] Based on the result of this determination, the server device 930 transmits a control signal for electrical continuity to the second smart plug SP2.
[0073] The second smart plug SP2 receives the control signal for electrical conduction and switches the conduction state of the relay switch 32.
[0074] The third smart plug SP3 and the fourth smart plug SP4 receive an electrical disconnection control signal, and the relay switch 33 and the relay switch 34 are maintained in the disconnected state.
[0075] As a result, as shown in the period PRD3 in FIG. 4, the pumps 81 and 82 are driven simultaneously, achieving a higher drainage capacity.
[0076] 4 , the accumulated water is drained by the normal operation of the pumps 81 and 82. In this case, the first smart plug SP1 and the second smart plug SP2 provide waveforms of applied voltage values and consumed current values corresponding to the normal operation of the pumps 81 and 82. The first smart plug SP1 and the second smart plug SP2 generate a time characteristic of power consumption from the time characteristics of the applied voltage values and consumed current values, and transmit this to the server device 930 as power consumption information.
[0077] The server device 930 receives the power consumption information and detects from pre-stored conditions that pumps 81 and 82 are operating normally. Since pumps 81 and 82 are operating stably in normal operation, the server device 930 determines that pumps 81 and 82 should continue to be operated as is and that there is no need to operate the other pumps 83 and 84.
[0078] Based on this determination result, the server device 930 sends an electrical conduction control signal to the first smart plug SP1 and the second smart plug SP2, and sends an electrical disconnection control signal to the third smart plug SP3 and the fourth smart plug SP4.
[0079] The first smart plug SP1 and the second smart plug SP2 receive the control signal for electrical conduction, and maintain the conductive state of the relay switch 31 and the relay switch 32.
[0080] The third smart plug SP3 and the fourth smart plug SP4 receive an electrical disconnection control signal, and the relay switch 33 and the relay switch 34 are maintained in the disconnected state.
[0081] Next, as shown in period PRD4 in Figure 4, when heavy rain changes to light rain, normal operation of both pumps 81 and 82 results in excess drainage capacity. In this case, the first smart plug SP1 and the second smart plug SP2 obtain waveforms of applied voltage values and current consumption values corresponding to light load operation (operation with a lower on-duty than normal operation) of pumps 81 and 82. The first smart plug SP1 and the second smart plug SP2 generate time characteristics of power consumption from the time characteristics of applied voltage values and current consumption values, and transmit this to the server device 930 as power consumption information.
[0082] The server device 930 receives the power consumption information and detects from pre-stored conditions that the pumps 81 and 82 are operating under light load. The server device 930 determines that the pump 81 can also discharge water, and determines to continue operating the pump 81 and to stop the pump 82.
[0083] Based on this determination result, the server device 930 sends an electrical conduction control signal to the first smart plug SP1, and sends an electrical disconnection control signal to the second smart plug SP2, the third smart plug SP3, and the fourth smart plug SP4.
[0084] The first smart plug SP1 receives the control signal for electrical conduction and maintains the relay switch 31 in a conductive state.
[0085] The second smart plug SP2, the third smart plug SP3, and the fourth smart plug SP4 receive an electrical disconnection control signal, and the relay switch 32, the relay switch 33, and the relay switch 34 are maintained in the disconnected state.
[0086] As a result, only the pump 81 operates normally, as shown in the period PRD5 in FIG. 4, and proper drainage is performed.
[0087] In this way, the integrated control system 1 can optimally control the operation of the multiple pumps 81-84 according to the operation and drainage states of the multiple pumps 81-84 without having to monitor the operation and drainage states of the multiple pumps 81-84 on-site.
[0088] By monitoring the power consumption information, the integrated control system 1 can detect an abnormal state, such as when a running pump is unplugged from the multi-power tap 10. Specifically, when a running pump is unplugged from the multi-power tap 10, the power consumption suddenly drops to zero, and this state continues. By detecting this phenomenon, the server device 930 can detect that the pump has been unplugged from the multi-power tap 10.
[0089] When the server device 930 detects that the pump has been unplugged from the multi-power tap 10, it transmits an alarm to, for example, the control terminal 920. This allows the administrator operating the control terminal 920 to know that the pump has been unplugged from the multi-power tap 10.
[0090] Furthermore, there is a risk that another load may be connected after the pump is unplugged from the multi-power tap 10. For this reason, the multi-power tap 10 can be controlled to maintain the electrical disconnection state after detecting that the pump has been unplugged (after notifying of an abnormality) regardless of whether a control signal is sent.
[0091] Furthermore, the multi-power tap 10 may be provided with a switch for canceling the electrically disconnected state, so that the power tap can be restored to a conductive state when the load is intentionally swapped.
[0092] The multi-power tap 10 can also detect that the pump has been unplugged based on power consumption information detected by the multi-power tap itself.
[0093] 5 is an equivalent circuit diagram showing an example of a derivative configuration of a multi-power tap. As shown in FIG. 5, the multi-power tap 10X differs from the multi-power tap 10 described above in that the AC-DC converter 210, the microcomputer 211X, the communication unit 214, and the antenna 215 are combined into one unit that is shared by multiple power jacks 11-14.
[0094] In this configuration, the microcomputer 211X assigns an identification ID to each of the power jacks 11-14 and transmits power consumption information, thereby enabling the multi-power tap 10X to achieve the same control as the multi-power tap 10.
[0095] Furthermore, the multi-power tap 10X has fewer components than the multi-power tap 10, which allows for, for example, miniaturization.
[0096] Second Embodiment An integrated control system for electrical tools for construction work according to a second embodiment of the present invention will be described with reference to the drawings.
[0097] 6A and 6B are external perspective views of a power adapter used in an integrated control system for electrical tools for construction work according to a second embodiment of the present invention.
[0098] As shown in Figures 6(A) and 6(B), the power adapter 10A includes a cylindrical housing 100A, a power jack 11, and a power plug 102. The housing 100A has an end face E1 at one end and an end face E2 at the other end. The power jack 11 is formed on the end face E1. The power plug 102 is formed on the end face E2. The power adapter 10A corresponds to the "connection control member" of the present invention.
[0099] The housing 100A contains the circuit configuration of the first smart plug SP1 described above.
[0100] Thus, the power adapter 10A includes a pair of the power jack 11 and the power plug 102.
[0101] Such a power adapter 10A is used, for example, as follows: Figure 7 is a perspective view showing an example of use of the power adapter according to the second embodiment of the present invention.
[0102] 7, the power adapter 10A is connected to the electric drum 910A. The power plug 810 of the pump 81 is connected to the power adapter 10A. That is, the pump 81 is connected to the electric drum 910A through the power adapter 10A.
[0103] Then, the control terminal 920 is used to register in advance "which type of electrical work tool (e.g., a pump) is connected to which power strip of the electric drum 910A." This allows the integrated control system 1A to control each electrical work tool in conjunction with other tools at the optimal timing, achieving the same effects as the integrated control system 1.
[0104] The power adapter 10A can also be built into the electric drum 910A.
[0105] Third Embodiment An integrated control system for electrical tools for construction work according to a third embodiment of the present invention will be described with reference to the drawings.
[0106] 8A and 8B are external perspective views of a power adapter used in an integrated control system for electrical tools for construction work according to a third embodiment of the present invention.
[0107] 8A and 8B, power adapter 10B differs from power adapter 10A according to the second embodiment in the shape of power jack 11B and a locking mechanism (not shown). The rest of the configuration of power adapter 10B is the same as that of power adapter 10A, and a description of similar parts will be omitted.
[0108] The power jack 11B is shaped so that it can rotate when a power plug is inserted into it.
[0109] A locking mechanism (not shown) is provided inside housing 100B of power adapter 10B. The locking mechanism is controlled by the control terminal 920 via a microcomputer to lock the power plug inserted into power jack 11B and prevent it from being removed from power jack 11B. The locking mechanism is controlled by the control terminal 920 via a microcomputer to unlock the power plug inserted into and locked in power jack 11B, allowing it to be removed from power jack 11B.
[0110] Such a power adapter 10B is used, for example, as follows: Fig. 9 is a perspective view showing an example of use of the power adapter according to the third embodiment of the present invention.
[0111] As shown in Figure 9, the building that serves as the construction site has multiple floors (three floors in this example), and electric drums, power adapters, and construction electrical tools are placed on each floor. Specifically, they are as follows: On the first floor, electric drum 910B, power adapter 10B1, and construction electrical tool 81X are placed; on the second floor, electric drum 920B, power adapter 10B2, and construction electrical tool 82X are placed; and on the third floor, electric drum 930B, power adapter 10B3, and construction electrical tool 83X are placed.
[0112] The power plug 810 of the construction tool 81X is connected to and locked with the power adapter 10B1, which is connected to the electric drum 910B.
[0113] The power plug 820 of the construction electric tool 82X is connected to and locked with the power adapter 10B2, which is connected to the electric drum 920B.
[0114] The power plug 830 of the construction electric tool 83X is connected to and locked with the power adapter 10B3, which is connected to the electric drum 930B.
[0115] This configuration makes it possible to link specific construction electrical tools to power adapters, preventing unauthorized personnel from switching between them. Therefore, as shown in Figure 9, when various construction electrical tools are connected to multiple electric drums across multiple floors, remote control can be performed without any problems even if a specific construction electrical tool is being used across floors.
