  DESCRIPTION OF EMBODIMENTS Preferred embodiments (examples) of the present invention will be described below with reference to the accompanying drawings.

  With reference to FIG. 1, the basic structure of the electric field communication system according to the present invention will be conceptually described. In FIG. 1, 10 is an electric field communication system according to the present invention, and 11 is an object to which the electric field communication system 10 is applied. The object 11 is typically a machine, and may be a device, a device, or the like. A typical machine is a mobile machine such as an automobile. Other mobile machines include, for example, motorcycles, bicycles, flying objects, track vehicles, and water vehicles. The object 11 such as a machine, device, or apparatus can be a machine, device, or apparatus that is installed or equipped in a public facility such as a medical facility or a traffic facility.

The object 11 is an object on which an operation such as driving or input is performed by the person 12. Examples of the person 12 include a driver, an occupant, an operator (operator), a passer-by, and a user. The object 11 includes an operation input unit 11 </ b> A operated by a person 12. The object 11 receives a control command and various data based on the formation of the operation relationship when the person 12 operates the operation input unit 11A. Specifically, the operation or the like (or “operation relation”) of the operation input unit 11A is, for example, an input based on an action using a body such as a hand or a foot of the person 12, or the person 12 with respect to the operation input unit 11A. It is an attitude such as an operation input, or a distance relationship between the operation input unit 11A configured as a sensor means and the person 12 or a movement relationship of the person 12 with respect to the operation input unit 11A. The operation of the operation input unit 11 </ b> A is established as an “operation relationship” in the relationship with the person 12. As described above, an operation relationship including the person 12 is formed between the operation input unit 11A of the object 11 and the person 12, and a physical connection region 13 is created based on the operation relation. It is done. The connection area 13 is “operated (including“ providing information / commands ”)” and “operated” (“information / commands”) between the machine 12, the machine 11, the device 11, the object 11, and the person 12. This is a physical connection area between a machine and the like “including a command etc.” and includes a contact and non-contact relationship. The connection area (operation relation) 13 shown in FIG. 1 is formed between, for example, the operation input unit 11A and the hand of the person 12 who operates this.
In addition, with regard to “operation-related connection areas”, the concept is further expanded in the case of devices such as electric beds installed in medical facilities, etc. Even when the posture (including the state) is taken, an electric bed or the like and a person are connected to each other in an operational relationship.

  Next, in the electric field communication system 10, at least two electric field communication devices 14 and 15 are provided on the object 11 side. The electric field communication devices 14 and 15 are communication means for enabling electric field communication. The electric field communicators 14 and 15 are not configured as a fixer, one of which is installed on the machine side and the other is mounted on the person side, but both are mounted on the object 11 side. (Fixed side electric field communication device). Therefore, the person 12 does not have to carry and carry a special mobile device for electric field communication, that is, a mobile electric field communication device. That is, it is not necessary for a person to prepare and have means for electric field communication.

  The number of electric field communication devices 14 and 15 is arbitrary, and may be three or four.

  The electric field communication devices 14 and 15 can be configured to include a transmission / reception unit for performing electric field communication, a transmission unit for performing only electric field transmission, or a reception unit for performing only electric field reception. The configuration of the electric field communication devices 14 and 15 can be arbitrarily selected according to the use or purpose. In the example shown in FIG. 1, among the electric field communication devices 14 and 15, for example, the electric field communication device 14 is installed in association with the operation input unit 11 </ b> A of the object 11, while the electric field communication device 15 is one of the objects 11. It is installed in relation to other parts of the department. A more detailed internal configuration of the electric field communication devices 14 and 15 will be described with reference to a first embodiment described later.

  Each of the two electric field communication devices 14 and 15 is arranged at a different location between the person 12 and contributes to forming a communication path (connected state or connected state) with the person 12 interposed. The person 12 moves so as to approach the operation input unit 11A of the object 11 from another place, sets the body at a predetermined position (installation position of the electric field communication device 15), and at that position, moves the hand. To take a necessary posture or perform necessary actions with respect to the operation input unit 11A. As described above, the connection region 13 is created between the operation input unit 11A of the object 11 and the hand of the person 12 who operates the object input unit 11A. When the person 12 operates the operation input unit 11A with his / her hand, the body of the person 12 and each of the electric field communication devices 14 and 15 are connected in electric field communication. As a result, the communication path 16 is formed between the two electric field communication devices 14 and 15 with the body of the person 12 interposed. Thus, the electric field communication system 10 is constructed, and the two electric field communication devices 14 and 15 function as a human body detection unit for the person 12.

  The two electric field communication devices 14 and 15 are each connected to a control processing unit 17 built in the object 11. In the electric field communication system 10, when the communication path 16 is formed, the control processing unit 17 of the target 11 has the body of the person 12 in a predetermined position in the positional relationship with the operation input unit 11 </ b> A of the target 11. Can be detected. Furthermore, information (data) or the like related to the person 12 is transmitted from the electric field communication devices 14 and 15 side to the control processing unit 17 of the object 11 as necessary. That is, the control processing unit 17 of the object 11 can receive information (data) related to the person 12. The control processing unit 17 of the target object 11 performs human body detection related to the person 12 through the above processes, further obtains information (data) related to the person 12 as necessary, and then generates and outputs a control command. For example, the operation of the driving device 18 incorporated in the object 11 is controlled.

  In the above, since the electric field communication device 14 is configured to relate to the operation input unit 11A with respect to the two electric field communication devices 14 and 15 configured as the human body detection means, the person 12 is from the side of the machine or the like that is the object 11. The person 12 is required to make a required posture or perform a required action with the operation input unit 11A of the object 11. In other words, the human body detection means composed of the two electric field communication devices 14 and 15 provided on the object 11 side is configured so that the person 12 existing in the operation-related connection region 13 can move the body to the operation input unit. 11A has a unique function and configuration as means for detecting whether or not a required posture or action required from the object 11 side is taken in the operation relationship with 11A.

  According to the configuration of the electric field communication system 10 according to the present invention applied to the object 11, both of the at least two electric field communication devices 14 and 15 are installed as different fixtures at different required locations on the object 11 side. Thus, the person 12 can form a communication path without carrying a special electric field communication mobile device. Further, regarding the person 12 existing in the connection area 13 of the operation relation, whether or not the person 12 is taking the required posture or action that the object 11 side asks the person regarding the operation relation with the operation input unit 11A. Can be detected.

  The above system configuration will be described from another point of view. An electric field communication device (moving side electric field communication device) that should be originally carried on the person 12 side as a mobile device is replaced with a second fixing device (fixed side electric field). As a communication device, the communication device is installed on the object 11 side which is a machine or the like. On the object 11 side, one electric field communication device is originally provided as a fixing device (first fixed electric field communication device). According to this system configuration, when the body of the person 12 is used as a communication path for electric field communication, the person 12 does not need to carry an electric field communication device specially and can be handled only by the body. Have.

  Next, a first embodiment of the electric field communication system according to the present invention will be described with reference to FIG. 2 and FIG. This 1st Embodiment is an example which applied the electric field communication system to control of the engine of a motor vehicle. The content of the engine control is that the engine is not operated from the viewpoint of safety when the driver is sitting in the driver's seat and not touching the steering wheel in the driving posture.

  The configuration of the first embodiment will be described with reference to FIG. The above-described object 11 is an automobile, and more specifically, an engine system 21 mounted on the automobile. The engine system 21 includes an engine 22 that is a driving device of an automobile, a processing unit 23 that gives a control command to each component of an electronic circuit unit of the engine 22, and a control unit 24 that outputs a control signal related to the operation of the engine 22. Built-in. The control unit 24 generates and outputs a control signal required for drive control of the engine 11 based on information related to human detection given from the human detection means of the electric field communication system 10. The processing unit 23 generates a control command based on the control signal given from the control unit 24 and gives it to the engine 22.

  The electric field communication system 10 includes two electric field communication devices 25 and 26. On the other hand, the electric field communication device 25 is attached to a position of a handle 27 of the automobile by being incorporated therein. The handle 27 is an operation input device (steering device) that determines the traveling direction of the automobile. The other electric field communicator 26 is attached to the seat 28 of the driver's seat of the automobile by being incorporated therein. The seat 28 is where the driver sits. In the configuration of the first embodiment, the electric field communication device 25 is configured to have a function (reception function) as an electric field communication receiver, and the electric field communication device 26 has a function (transmission function) as an electric field communication transmitter. It is configured as follows.

  The electric field communication device 25 includes an electrode 25a, an electric field communication receiving unit 25b, a CPU 25c, and an I / F (interface unit) 25d. The electric field communication device 26 includes an electrode 26a, an electric field communication transmission unit 26b, a CPU 26c, and an I / F (interface unit) 26d. The electric field communication device 25 is electrically connected to the control unit 24 of the engine system 21 via the I / F 25d. The electric field communication unit 26 is electrically connected to the control unit 24 of the engine system 21 via the I / F 26d.

  The electric field communication system 10 having the above configuration is supplied with electric power from an in-vehicle battery (not shown) and kept in an active state even when the power switch of the automobile is turned off.

  In the electric field communication system 10 described above, when the driver 29 gets into the car, sits on the seat 28 and holds the handle 27 with his / her hand, as described above, the operation relationship between the driver's 29 hand and the handle 27 is established. Connection region 13 is created. Further, when the handle 27 is gripped to operate the handle 27, the body of the driver 29 is interposed between the electric field communication device 26 provided on the seat seat 28 and the electric field communication device 25 provided on the handle 27. Thus, the communication path 16 in the electric field communication system 10 is generated. When this communication path 16 is generated, electric field communication becomes possible through the body of the driver 29. In the case of this embodiment, it is possible to transmit information (data) or the like from the electric field communication device 26 to the electric field communication device 25 as indicated by an arrow 30.

  According to the electric field communication system 10 described above, when the driver 29 sits on the seat 28 of the automobile and grips the handle 27 for driving, the communication path 16 for electric field communication is formed, and the two electric field communication devices 25, 26 are formed. It is possible to detect the presence of a person in the operation-related connection area 13 based on the person detection means formed by the above. Further, it is understood that the driver 29 sitting on the driver's seat 28 is in the state of holding the handle 27 (driving posture) on the side of the engine system 21 of the vehicle by generating the communication path 16. In addition, it is possible to detect whether or not the driver 29 is taking the driving posture (or driving action) desired for the driver. In other words, when the driver 29 is detected, it can be detected that the driver 29 is grasping the handle 27, and when the driver 29 is not detected, the driver 29 is not grasping the handle 27 or the seat 28 is It turns out that it is not in place.

  Next, operation control of the engine 22 of the automobile will be described with reference to the flowchart of FIG. In FIG. 3, a broken-line block 31 indicates a process when the engine system 21 is in a stopped state, and a broken-line block 32 indicates a process when the engine system 21 is in an operating state.

  In the block 31 in a state where the engine system 21 is stopped, electric power is supplied from the in-vehicle battery to the electric field communication system 10 side, and the electric field communication system 10 is in an active state. In the electric field communication system 10, the electric field communication device 26 having a transmission function is performing polling in a standby state in which the engine 22 is stopped (step S11). Then, in the next stage, it is determined whether or not the communication path 16 is formed in accordance with a predetermined posture (required driving posture) related to driving required from the side of the vehicle when there is a human body approach (determination step S12). ). That is, it is determined whether or not the driver 29 sits on the seat 28 and takes the required driving posture required from the automobile side in that state. If NO in determination step S12, the process returns to step S11. If YES, the process proceeds to the next step S13. In step S13, an operating condition for operating the engine system 21 is established. The operating condition is, for example, that the power switch is automatically turned on, and is a condition for enabling the operation of the engine 22 and driving the automobile. After step S13 is executed, the process proceeds to block 32.

In block 32, first, the engine system 21 starts operation (step S14). Thereafter, the electric field communication device 26 performs polling during operation of the engine 22 (step S15). In the next stage, it is determined whether a human body is detected and the communication path 16 is formed (determination step S16). That is, it is determined whether or not the driver 29 continues to sit on the seat 28 and takes the required driving posture required from the automobile side. If YES in determination step S16, the process returns to step S15. If NO, the process proceeds to the next step S17. If YES in the determination step S16, it means that the driver 29 is sitting on the seat 28 and continuously maintaining the driving posture and driving the automobile. If YES in decision step S16, step S15 and decision step S16 are repeated. If NO in the determination step S16, it means that the driver 29 does not take the driving posture required from the automobile side. Therefore, in the next step S17, a warning to stop the engine system 21 is issued to the driver 29.
Examples of warnings include an emergency warning table on the display panel and a warning sound generated by a sound generator. Thereafter, in determination step S18, it is determined again whether a human body is detected and the communication path 16 is formed. This is because the driver 29 may take a driving posture due to the warning. If YES in the second determination step S18, the process returns to step S15. If NO, the process proceeds to step S19. By returning to step S15, it is assumed that the problem related to the driving posture of the driver 29 has been solved, and the operation of the engine system 21 is continued. When the process proceeds to step S19, the stop condition of the engine system 21 is established assuming that the driver 29 does not maintain the required driving posture. The stop condition is, for example, that the power switch is automatically turned off. As a result, the engine system 21 stops in the next step S20.

  According to said 1st Embodiment, the electric field communication system 10 which concerns on this invention was applied to operation control of the engine system 21 of a motor vehicle. Thus, when viewed from the side of the automobile, a driver 29 in the driver's seat (seat seat 28) is requested by the automobile side by using human body detection means including electric field communication devices 25 and 26 connected to the engine system 21. It is possible to accurately determine whether or not a required posture is taken, and it can be effectively used for automatic operation of the engine system 21 or the like. In this example, it is applied to the engine system 21 of the automobile, but it is needless to say that it can be applied to other systems mounted on the automobile.

  Next, a first modification of the first embodiment will be described with reference to FIG. FIG. 4 is a modification of the configuration shown in FIG. In this modified embodiment, the electric field communication system 10 is equipped with three electric field communication devices. In FIG. 4, an electric field communication device 41 is further provided in addition to the electric field communication devices 25 and 26 described above. Other configurations are the same as those described in FIG. The electric field communication device 41 is attached in association with the brake pedal 42. Between the brake pedal 42 and the driver's 29 foot, when the driver 29 steps on the brake pedal with that foot, an operation-related connection region 14 is created. The electric field communication device 41 is electrically connected to the control unit 24 of the engine system 21. The electric field communication device 41 has a built-in electric field communication receiving unit and has the same internal configuration as the electric field communication device 25. Therefore, when the driver 29 sitting on the seat 28 and in the driving posture steps on the brake pedal 42, the brake pedal 42 and the driver are added to the communication path 16 in addition to the portion of the path path to the electric field communication device 25. In the connection region 13 of the operation relationship with 29 feet, a portion of the communication path to the electric field communication device 41 is further generated. Data can be transmitted as indicated by an arrow 43 by the portion of the communication path to the electric field communication device 41 in the communication path 16.

  As described above, when the electric field communication system 10 provided for the engine system 21 includes the three electric field communication devices 25, 26, and 41, the electric field communication device is interposed through the body of the driver 29 sitting on the seat seat 28. Two communication paths (connected state or connected state) between two pairs of electric field communication devices between 25 and 26 and between electric field communication devices 25 and 41 can be established. Even in such a configuration, either or both of the communication paths can be selected based on the priority standard corresponding to the operation purpose on the engine system 21 side. The selection means for performing the selection can be provided in the electric field communication device 26 on the transmission side, for example. That is, on the premise of the process of the flowchart described with reference to FIG. 3 in the first embodiment, for example, in the execution of polling of the electric field communication device 26 having a transmission function in standby, the electric field communication system 10 Since the ID of each device is known in advance, the two electric field communication devices 25 and 41 on the receiving side can be polled alternately. Then, by polling the two electric field communicators 25 and 41 on the receiving side alternately, for example, when both are detected, the engine 22 is started, or an electric field having a high priority based on the priority criteria. When the communicator 25 is detected, the electric field communicator 41 is then polled, and the engine 22 is started after detecting the polling. Further, when the polling of the electric field communication device 26 during engine operation is performed, only the electric field communication device 41 on the brake pedal 42 side is periodically polled, and the communication path 16 is formed with the electric field communication device 41. Then, the warning step (S17) and the stop step (S19) corresponding to the subsequent conditions are executed.

  When the communication path 16 is formed between the transmission-side electric field communication device 26 and one or both of the reception-side electric field communication device 25 and the electric field communication device 41, the communication path 16 is The data transmission can be performed from the electric field communication device 26 on the transmission side via the communication destination ID designation.

  In the above description of the embodiment, the electric field communication system 10 is configured to include the three electric field communication devices 25, 26, and 41. However, the electric field communication system 10 may be configured to include more than three electric field communication devices. it can.

  Next, a second modification of the first embodiment will be described with reference to FIG. FIG. 5 shows a configuration in which four electric field communication devices are provided in the electric field communication system 10. As described above, the pair of electric field communication devices 25 and 26 is a human detection means mounted on the seat 28 of the driver's seat for controlling the operation of the engine system 21 of the automobile, and a person (driver 19) is interposed. Then, the connection region 13 having the above-described operation relationship is created between the handle 27 and the driver 29, and the communication path 16 is generated between the electric field communication devices 25 and 26 through the body of the driver 29.
