Note that the operating frequency is different between FIG. 1 and FIGS. 2 and 3 . In this case, the control signal is a power feeding start notification signal. Further, the driving energy is the circuit operating energy (power supply) and the ignition energy (power supply) of the electronic circuit 120 (see FIG. 11) of the wireless ignition unit 110, and the control signal is the operation of the electronic circuit 120.

When the drive energy (circuit operation energy) is sufficiently stored, the unit-side controller 110D (see FIG. 11) of the electronic circuit 120 is activated. When the unit-side control device 110D (see FIG. 11) is activated, charging of ignition energy is started based on the received control signal (in this case, the power supply start notification signal). When the charging of the ignition energy is completed, the unit-side control device 110D (see FIG. 11) sends a response signal (in this case, a charging completion signal) to the communication section 110C (see FIG. 11) and the unit-side transmitting antenna 110B (see FIG. 11). 11) in a wireless manner.

● [Communication between wireless ignition operator 40 and wireless ignition unit 110 (Fig. 14)]
Next, referring to FIG. 14, in the configurations shown in FIGS. 1, 4, and 11, the communication operations of the above-described "(e) feeding start notification signal transmission step" and "(f) charging completion signal response step" explain. FIG. 14 shows a wireless ignition operator 40 and a plurality of wireless ignition units 110 (001) to 110 (027) (27 wireless ignition units 110 are used in example 1A of FIG. 1). An example of communication that takes place between them is shown in chronological order. The communication shown in FIG. 14 will be described in order below.

At the start of power feeding, the wireless ignition operating device 40 (operating device-side control device 42 ) transmits driving energy and control signals via the operating device-side transmitting antenna 10 . The control signal in this case is a power supply start notification signal CAR (one of a plurality of control signals), and the power supply start notification signal CAR includes designation information, sleep time information, response repetition number information, and the like. there is

The designation information is identification information assigned to each wireless ignition unit, and different designation information is stored in the ID storage device 132 (see FIG. 11) in each wireless ignition unit 110 . For example, in the ID storage devices 132 of the wireless ignition units 110(001) to 110(027), values 001 to 027 are stored as designation information. The designation information included in the power supply start notification signal CAR includes one or more pieces of designation information that designate the wireless ignition unit 110 corresponding to the fireball to be launched this time. In this example, all of the wireless ignition units 110(001) to 110(027) are designated by designation information.

The sleep time information is the time to put the unit-side control device 110D of the wireless ignition unit 110 designated by the designation information into the sleep state when charging the ignition energy. When the unit-side control device 110D designated by the designation information starts charging the energy for ignition, it shifts to a sleep state during the sleep time based on the sleep time information, and wakes up from the sleep state after the sleep time has elapsed. to resume operation. An appropriate sleep time is set according to the capacity, type, charging time, number, etc. of first power storage unit 110E and second power storage unit 110F shown in FIG.

The response repetition number information is a response signal (charging completion signal) of the unit-side control device 110D of the wireless ignition unit 110 designated by the designation information, which wakes up after the sleep time has elapsed. ) is the number of repetitions of transmission. The response repetition count information is, for example, a number of "1" or more, and an appropriate value is set. When the unit-side control device 110D designated by the designation information wakes up from the sleep state, if the charging of the ignition energy has been completed and the number of repetitions of transmission has not reached the number of repetitions of response, the unit-side control device 110D outputs a charge completion signal. It transmits once, counts the number of transmission repetitions, and shifts to the sleep state again.

Each of the wireless ignition units 110 (001) to 110 (027) that has received the power supply start notification signal CAR stores the designation information included in the received power supply start notification signal CAR in its own ID storage device 132. When the specified information matches, charging of second power storage unit 110F (see FIG. 11) is started, and charging start signal ACK, which is one of the response signals, is transmitted to wireless ignition manipulator 40. . The charging start signal ACK from each of the wireless ignition units 110(001) to 110(027) includes designation information stored in each ID storage device 132 (see FIG. 11). Upon receiving the charging start signals ACK001 to ACK027, the wireless ignition operation device 40 receives the charging start signal from which wireless ignition unit based on the specified information included in the charging start signal ACK. It can be recognized whether it is ACK.

All the wireless ignition units 110(001) to 110(027) return the charge start signal ACK in response to the power supply start notification signal CAR once, but it is necessary to avoid interference. Therefore, each wireless ignition unit 110 transmits the charge start signal ACK with a standby time corresponding to the value of its own designation information from the timing of receiving the power supply start notification signal CAR, for example. By doing so, the transmission timing of the charging start signal ACK from each wireless ignition unit 110 is shifted, and interference does not occur.

The example shown in FIG. 14 shows an example in which the wireless ignition units 110(001) to 110(027) wait for a standby time according to the value of each designated information, and then transmit the charge start signal ACK. there is For example, the standby time of the wireless ignition unit 110 (001) is set to 1*Td [ms], and the standby time of the wireless ignition unit 110 (002) is set to 2*Td [ms]. . "Td" is a constant for setting the waiting time, and is set to an appropriate value.

By receiving the charge start signal ACK from all the wireless ignition units 110 designated by the designation information included in the power supply start notification signal CAR, the wireless ignition operation device 40 controls all the wireless devices designated by the designation information. It can be recognized that charging has started in the type ignition unit 110 .

After transmitting the charging start signal ACK, the unit-side control devices 110D of the wireless ignition units 110(001) to 110(027) shift to the sleep state. The example of FIG. 14 shows an example in which the sleep time specified by the sleep time information is "T seconds". As shown in FIG. 14, the wireless ignition unit 110 (001) shifts to a sleep state for T seconds after transmitting the charging start signal ACK001. Similarly, after transmitting the charging start signal ACK002, the wireless ignition unit 110 (002) shifts to a sleep state for T seconds, and after transmitting the charging start signal ACK027, the wireless ignition unit 110 (027) sleep state. In the example of FIG. 14, the sleep state is indicated by a dotted line together with "SLP". The example of FIG. 14 shows that when the transmission timings of the charging start signals ACK001 to ACK027 deviate, the transition timings of the wireless ignition units 110 to the sleep state also deviate.

Note that charging after power supply start notification signal CAR is performed for both first power storage unit 110E and second power storage unit 110F by short-circuiting charge switch 135 in FIG. As will be described later, initially, charging switch 135 is opened for preprocessing, and only first power storage unit 110E is charged. By charging the first power storage unit 110E, the operation of the unit-side control device 110D and the like becomes possible, and pre-processing of charging is performed. In the example of FIG. 14, it has been described that the charging of second power storage unit 110F is started after the charging start signal ACK is transmitted. While the wireless ignition unit 110 is in the sleep state, the unit-side control device 110D and the like do not operate, so charging is continued with only the minimum sleep power consumption.

The wireless ignition units 110(001) to 110(027) wake up after the lapse of T seconds after transitioning to the sleep state, and start the second power storage unit based on the detection signal from the power storage state detection circuit 137 in FIG. Check whether charging of 110F is completed. Then, each of the wireless ignition units 110 (001) to 110 (027) outputs the charge completion signals FINC001 to FINC027, which are one of the response signals, when charging of the second power storage unit 110F is completed. Send.

In the example shown in FIG. 14 , wireless ignition unit 110 (001) has completed charging of the second power storage unit at time te001, and wakes up after T seconds have passed since it started transitioning to the initial sleep state. It shows a state in which the charging completion signal FINC001 is transmitted after the charging completion signal FINC001 has been raised. After transmitting the charging completion signal FINC001, the unit-side control device 110D of the wireless ignition unit 110 (001) shifts to the sleep state again. By shifting to the sleep state even after charging is completed, power consumption is avoided as much as possible and the amount of power stored in second power storage unit 110F is maintained. Regarding wireless ignition unit 110 (002) and wireless ignition unit 110 (027), charging to the second power storage unit has not been completed at time te001. It shows an example in which the signal FINC is not transmitted and the sleep state is entered again. In the example shown in FIG. 14, wireless ignition unit 110 (002) has completed charging second power storage unit 110F at time te002. Further, in wireless ignition unit 110 (027), charging of second power storage unit 110F is completed at time te027. The example shown in FIG. 14 shows an example in which the wireless ignition units 110 (002) and 110 (027) transmit the charge completion signal FINC002 and the charge completion signal FINC027 at subsequent wakeups.

Each of the wireless ignition units 110(001) to 110(027) wakes up again after T seconds have elapsed after the second transition to the sleep state, and confirms the state of charge of the second power storage unit 110F. In the example shown in FIG. 14, during the second wakeup, wireless ignition unit 110 (001) (charging completed at time te001), wireless ignition unit 110 (002) (charging completed at time te002) However, charging of second power storage unit 110F is completed. Therefore, the wireless ignition unit 110 (001) and the wireless ignition unit 110 (002) transmit the charge completion signal FINC001 and the charge completion signal FINC002 respectively at the time of the second wakeup, and shift to the sleep state. Note that wireless ignition unit 110 (027) has not yet completed charging second power storage unit 110F at the time of the second wakeup (charging is completed at time te027). Therefore, the wireless ignition unit 110 (027) shifts to the sleep state without transmitting the charge completion signal FINC even when waking up for the second time.

In the example shown in FIG. 14, the wireless ignition unit 110 (001) transmits the charge completion signal FINC001 during the first wakeup, and transmits the charge completion signal FINC001 during the second and subsequent wakeups. to do is not necessary. However, in order for the wireless ignition manipulator 40 to reliably recognize that charging of all the wireless ignition units 110(001) to 110(027) has been completed, the charge completion signal is also generated at the second and subsequent wakeups. FINC001 is being sent. In particular, the wireless ignition unit 110 that has completed charging early is considered to be in an environment that is advantageous for wireless charging (close to the operating device side transmitting antenna 10, etc.), and even if the power consumption due to the transmission of the response signal increases, Since it is considered that the charge amount will be replenished immediately, there is no particular problem even if it is transmitted every wakeup. However, when the capacity of the second power storage unit 110F is relatively small, etc., the wireless ignition unit 110 that has once transmitted the charge completion signal FINC does not transmit the charge completion signal FINC when waking up thereafter. You may do so.

In the example shown in FIG. 14, charging of the second power storage unit 110F in each of the wireless ignition units 110(001) to 110(027) is completed by the time of the third wakeup. In this case, each wireless ignition unit 110 wakes up after a lapse of T seconds from the start of transition to the sleep state, confirms the state of charge of second power storage unit 110F, and if charging is completed transmits a charge completion signal FINC. At this time, when the wireless ignition manipulator 40 confirms that the charging completion signals FINC001 to FINC027 have been received from all the wireless ignition units 110(001) to 110(027) specified by the specified information, the power feeding operation is started. finish.

If "3" is set in the response repetition count information included in the power feeding start notification signal CAR, the wireless device that does not transmit the charging completion signal FINC at this time (the time of the 3rd wakeup) If the ignition unit 110 is present, the operation may be terminated as an error, or the operation may be restarted from the transmission of the power feeding start notification signal CAR. By performing communication shown in the example of FIG. It can be confirmed from all the wireless ignition units 110(001) to 110(027) designated by the designated information that the second power storage unit 110F has been charged.

● [Processing procedure for operations shown in FIG. 14 (FIGS. 13, 15, and 16)]
A processing procedure of the wireless ignition operation device 40 and the wireless ignition unit 110 for realizing the operation shown in FIG. 14 will be described with reference to the block diagram of FIG. 13 and the flow charts of FIGS. Steps S101 to S159 shown in FIGS. 15 and 16 are processes executed by the wireless ignition manipulator 40 according to the operation program, and steps S201 to S259 are performed by the respective wireless ignition units 110 (001) to 110 (027). is the processing executed according to the operation program.

FIG. 15 shows the pre-processing for charging shown in FIG. 14, and FIG. 16 shows the charging process (charging process for second power storage unit 110F) shown in FIG. First, the processing procedure of the pre-processing shown in FIG. 15 will be described.

● [Procedure for preprocessing (Fig. 15, Fig. 13)]
In step S101, the operating device-side control device 42 (see FIG. 13) of the wireless ignition operating device 40 starts wireless power supply operation, and the process proceeds to step S102. In FIG. 13 , an operating machine-side control device 42 wirelessly transmits driving energy via a communication unit 43 , a relay device 30 , and an operating machine-side transmitting antenna 10 . In each wireless ignition unit 110, the charging switch 135 and the ignition switch 138 (see FIG. 13) are opened as an initial state in which no power is supplied. In each wireless ignition unit 110, the received driving energy is charged in the first power storage unit 110E.

In step S102, the manipulator-side control device 42 waits until a certain period of time elapses, and after the certain period of time elapses, the process proceeds to step S103. Manipulator-side control device 42 waits while first power storage unit 110E (see FIG. 13) of wireless ignition unit 110 is charged (for a certain period of time). The wireless ignition unit 110 charges the first power storage unit 110E with driving energy for a certain period of time, and when the first power storage unit 110E is sufficiently charged, the unit-side control device 110D (see FIG. 13) is activated. operation is started.

In step S<b>103 , the controller-side control device 42 determines that the wireless ignition unit 110 can be preprocessed, and sets the wireless ignition unit 110 . Specifically, the controller-side control device 42 transmits an ignition delay time signal (one of the control signals) including designation information and an ignition delay time to each wireless ignition unit 110 . The ignition delay time is the delay time from when the unit-side control device 110D receives an ignition command signal (one of the control signals) to when the ignition is actually executed. The designation information is identification information stored in the ID storage device 132 (see FIG. 13) of each wireless ignition unit 110, as described above. By transmitting an ignition delay time signal, the operating device-side control device 42 can set which wireless ignition unit is to be ignited and with what delay time. The delay time can also be used as a time for shifting the charge start signal ACK shown in FIG. 14 or the transition to the sleep state. After performing the setting in step S103, the manipulator-side control device 42 advances the process to step S104.

In step S201, unit-side control device 110D receives the ignition delay time signal, and advances the process to step S202.

In step S202, the unit-side control device 110D extracts the specified information that matches the specified information stored in its own ID storage device 132 from the specified information included in the received ignition delay time signal. Then, the unit-side control device 110D acquires the ignition delay time associated with the extracted designation information, sets it as its own ignition delay time, and advances the process to step S203. If the received ignition delay time signal does not contain designation information that matches its own designation information, the unit-side control device 110D recognizes that ignition is not designated in this process, and returns to step S201. can be

In step S104, the operating device-side control device 42 transmits a check request signal (one of the control signals) including designation information to the wireless ignition unit 110, and proceeds to step S105. The check request signal is a signal requesting each wireless ignition unit 110 to perform self-diagnosis or the like.

In step S203, the unit-side control device 110D receives the check request signal, and proceeds to step S204.

In step S204, if the unit-side control device 110D includes specified information that matches the specified information stored in its own ID storage device 132 in the specified information included in the check request signal, the unit-side control device 110D is set in advance. Self-diagnosis such as continuity check is performed. Then, the unit-side control device 110D transmits a check result signal (one of the response signals) including the check result (normal or abnormal) and designation information, and advances the process to step S250 shown in FIG.

In step S105, the manipulator-side control device 42 receives the check result signal from each wireless ignition unit 110, and advances the process to step S106.

In step S106, the manipulator-side control device 42 receives check result signals from all the wireless ignition units 110 designated by the designation information, and all the check results included in all the check result signals are normal. It is determined whether or not. If all check results are normal (Yes), the process proceeds to step S150 shown in FIG. 16. If even one check result is abnormal (No), the process proceeds to step S107.

In step S107, the manipulator-side control device 42 returns the process to step S105 until the time is up, and until all the check results from all the wireless ignition units 110 specified by the specified information are normal, the step The processing of S105 to S107 is repeated. When the time is up in step S107 (Yes), the controller-side control device 42 advances the process to step S108.

In step S108, the manipulator-side control device 42 performs error processing and stops the operation. If the process proceeds to step S108, if at least one of the wireless ignition units 110 specified by the specified information has not transmitted a check result signal, or if at least one of the transmitted check result information This is when the timeout is reached when the check result of is abnormal. In this case, in order to give priority to safety, it is preferable to stop the progress of the subsequent processing.

In step S106, the operating device-side control device 42 receives check result signals from all the wireless ignition units 110 designated by the designation information, and if the check results of all the check result signals are normal ( Yes) and all the unit-side control devices 110D designated by the designation information in step S205 have transmitted the check result signal, the process proceeds to the charging process shown in FIG. The charging process referred to here is a charging process by wireless power supply to the second power storage unit 110F that stores energy for ignition. After the pre-processing shown in FIG. 15, the charging process shown in FIG. 16 is started.

● [Charging process procedure (Fig. 16, Fig. 14, Fig. 13)]
In step S150 shown in FIG. 16, the controller-side control device 42 starts the wireless power supply operation, and advances the process to step S151. The operator-side control device 42 wirelessly transmits driving energy via the communication unit 43 , the relay device 30 , and the operator-side transmission antenna 10 . However, if the wireless power feeding operation started in step S101 continues as it is, this control is unnecessary.

In step S151, the manipulator-side control device 42 transmits to the wireless ignition unit 110 a power feeding start notification signal CAR including designation information, sleep time information, and response repetition number information, as described with reference to FIG. The process proceeds to step S152.

The operator-side control device 42 executing the processes of steps S150 and S151 includes designation information that enables designation of a specific wireless ignition unit 110 from among a plurality of wireless ignition units 110, and controls the control device. It corresponds to the designated power supply start unit 42A (see FIG. 13) that transmits the power supply start notification signal CAR, which is one of the signals, via the operator-side transmitting antenna 10. FIG.

In step S250, the unit-side control device 110D receives the power supply start notification signal CAR as described with reference to FIG. 14, and proceeds to step S251.

In step S251, the unit-side control device 110D extracts the specified information that matches the specified information stored in its own ID storage device from the specified information included in the received power supply start notification signal CAR. Then, the unit-side control device 110D sets its own sleep time based on the sleep time information associated with the extracted designation information, and sets its own sleep time based on the response repetition count information included in the power supply start notification signal CAR. Sets the number of response repetitions for . Then, the unit-side control device 110D controls the charge switch 135 (charging control section, see FIG. 13) from the open state to the short-circuit state, and advances the process to step S252. Unit-side control device 110D starts charging second power storage unit 110F by controlling charging switch 135 (charging control unit) to be in a short-circuited state. In step S251, the unit-side control device 110D sets a number counter that counts the number of repeated responses to "1".

When the unit-side control device 110D executing the processes of steps S250 and S251 receives the power supply start notification signal CAR, the designation information included in the received power supply start notification signal CAR is changed to the designation stored in itself. It corresponds to the charging execution unit 131A (see FIGS. 11 and 13) that charges the second power storage unit 110F when the information matches.

In step S252, the unit-side control device 110D waits until the response timing, and when the response timing has arrived (Yes), the process proceeds to step S253. In waiting until the response timing, the engine waits for the delay time included in the ignition delay time signal received in step S201 of FIG. After the delay time associated with the designation information has passed, the unit-side control device 110D advances the process to step S253.

In step S253, the unit-side control device 110D transmits a charging start signal ACK (charging start signal ACK including designation information), which is one of the response signals, as described with reference to FIG. 14, and proceeds to step S254. proceed.

In step S152, the controller-side control device 42 performs reception processing of the charging start signal ACK, and advances the processing to step S153A. Since the charging start signal ACK is transmitted from each wireless ignition unit 110 with a time difference, the response waiting time depends on the response delay time of the wireless ignition unit 110 that finally transmits the charging start signal ACK. is set.

In step S153A, the operating device-side control device 42 determines whether or not the charging start signal ACK has been received from all the wireless ignition units designated by the designation information. When the charging start signal ACK has been received from all the wireless ignition units 110 specified by the specified information (Yes), the operating machine-side control device 42 advances the process to step S154 to start all the wireless ignition units specified by the specified information. If even one of the ignition units 110 has not received the charge start signal ACK (if there is even one wireless ignition unit that cannot confirm the charge start signal ACK) (No), proceed to step S153B. proceed.

When the process proceeds to step S153B, the manipulator-side control device 42 determines whether or not the response waiting time has elapsed for all the wireless ignition units 110 designated by the designation information. If the response waiting time has elapsed (Yes), the controller-side control device 42 proceeds to step S160, ends (stops) the power supply operation, and performs error processing, and if the response waiting time has not elapsed (No). returns the process to step S152 and waits for reception of the charging start signal ACK. When the response waiting time elapses, the controller-side control device 42 has even one wireless ignition unit for which the charging start signal ACK cannot be confirmed among all the wireless ignition units 110 specified by the specified information. , the process proceeds to step S160.

When the process proceeds to step S154, the manipulator-side control device 42 starts an internal timer that counts time in order to recognize the limit of waiting for subsequent reception (recognizes time up), and proceeds to step S155. proceed.

In step S254, unit-side control device 110D transitions to a sleep state, sleeps for the set sleep time, and continues charging second power storage unit 110F.

In step S255, the unit-side control device 110D automatically wakes up when the sleep time (T seconds) has elapsed after transitioning to the sleep state, and proceeds to step S256.

In step S256, unit-side control device 110D determines whether or not charging to second power storage unit 110F is completed based on the detection signal from power storage state detection circuit 137 (see FIG. 13), and charging is completed. If it is determined that the charging is completed (Yes), the process proceeds to step S257, and if it is determined that the charging is not completed (No), the process proceeds to step S258.

When the process proceeds to step S257, the unit-side control device 110D transmits a charge completion signal FINC (one of response information) including its own designation information, and proceeds to step S258.

A series of operations in steps S254, S255, S256, and S257 is a series of sleeps in which the device shifts to a sleep state, wakes up after the sleep time has elapsed, and transmits a charge completion signal FINC when charging is completed. Corresponds to the charging operation. Further, unit-side control device 110D executing the processes of steps S256 and S257, when charging to second power storage unit 110F is completed, sends charge completion signal FINC including designation information stored therein, It corresponds to the charging response executing section 131B (see FIGS. 11 and 13) that transmits via the unit-side transmitting antenna.

When proceeding to step S258, the unit-side control device 110D increments the number counter C, and advances the process to step S259.

In step S259, the unit-side control device 110D determines whether or not the value of the number counter C is equal to or greater than the number of response repetitions based on the response repetition number information included in the power supply start notification signal CAR received in step S250. judge. The unit-side control device 110D terminates the charging process if the response repetition count is greater than or equal to (Yes), and returns the process to step S254 if the response repetition count is less than the response repetition count (No), and enters the sleep state for T seconds again. to Although not shown, the unit-side control device 110D may perform the processing from step S250 when it receives the power supply start notification signal CAR again.

In step S259, the unit-side control device 110D starts charging the second power storage unit 110F by operating the charging control unit (charging switch 135) (putting it in a short-circuit state), and then performs a series of sleep charging operations. It is executed the number of times specified by the response repetition number information included in the power feeding start notification signal CAR.

In step S155, the controller-side control device 42 performs reception processing of the charging completion signal FINC, and proceeds to step S156.

In step S156, the operating device-side control device 42 determines whether or not the continuous charging time has elapsed. If not (No), the process returns to step S155. The charging continuation time is a time set based on the value of sleep time (T seconds)*response repetition count information. That is, it is the time until the wireless ignition unit 110 determines in step S259 that "number of times counter C≧number of repetitions of response". Therefore, for example, when the number of response repetitions is "three", the wireless ignition unit 110 is in the sleep state/wake-up three times and until charging completion confirmation is performed, the operating device-side control device 42 is kept in step S155. to monitor the charging completion signal FINC.

In step S157, the operating device-side control device 42 determines whether or not the charge completion signal FINC has been received from all the wireless ignition units 110 designated by the designation information. If the controller-side control device 42 has received the charge completion signal FINC from all the wireless ignition units 110 designated by the designation information (Yes), the process proceeds to step S159. If there is at least one wireless ignition unit 110 that has failed to receive the charge completion signal FINC among the wireless ignition units 110 specified by the specification information (No), the controller-side control device 42 proceeds to step S158. Proceed with processing.

The controller-side control device 42 executing the processes of steps S155, S156, and S157 receives the response from the wireless ignition unit 110 to the power feeding start notification signal CAR and one of the response signals, which is the completion of charging. is received from all the wireless ignition units 110 specified by the specified information included in the power feeding start notification signal CAR, via the operating device side receiving antenna. 42B (see FIG. 13).

When the process proceeds to step S158, the manipulator-side control device 42 sets the number of retransmissions of the power supply start notification signal CAR (although not shown, the number of retransmissions of the power supply start notification signal CAR is stored) to the set number of retransmissions. It is determined whether or not the above is satisfied. If the number of retransmissions is equal to or greater than the set number of retransmissions (Yes), the controller-side control device 42 proceeds to step S160, and if the number of retransmissions is less than the set number of retransmissions (No), returns the process to step S151. The set number of retransmissions is a number set in advance by an operator or the like, and is set to, for example, one or more times. By this step S158, the charging process shown in FIG. 16 can be repeated up to the set number of retransmissions until charging of all the wireless ignition units 110 designated by the designation information is completed.

When the process proceeds to step S159, the controller-side control device 42 terminates the wireless power supply operation (stops transmission of driving energy), and terminates the charging process. After that, although the description is omitted, the operator-side control device 42 transmits an ignition command signal including designation information to the wireless ignition unit 110 to perform ignition.

When the process proceeds to step S160, the manipulator-side control device 42 terminates the wireless power feeding operation (stops transmission of drive energy), and proceeds to step S161.

In step S161, the manipulator-side control device 42 performs error processing and stops the operation. When the process proceeds to step S161, retransmission of the power supply start notification signal CAR is repeated for the set number of retransmissions, and at least one of the wireless ignition units 110 designated by the designation information is charged even after the charging continuation time elapses. This is the case where the completion signal FINC has not been transmitted (or at least one has not transmitted the charge start signal ACK even though the response waiting time has elapsed). In this case, in order to give priority to safety, it is preferable to stop the progress of subsequent processing (ignition processing).

● [Charging process in case of electronic circuit 120B shown in FIG. 12]
Unlike the electronic circuit 120 shown in the example of FIG. 11, the electronic circuit 120B shown in the example of FIG. The difference is that In the electronic circuit 120B shown in the example of FIG. 12, the ignition switch 138 is in an open state as an initial state in which there is no power supply.

In the case of the electronic circuit 120B shown in the example of FIG. 12, the pre-processing shown in FIG. 15 is the same, so the explanation is omitted. Note that in the case of the electronic circuit 120B shown in the example of FIG. 12, the flow of the charging process flowchart shown in FIG. 16 is the same, but in the following steps, the processing contents are changed as follows.

In step S251, the unit-side control device 110D sets its own sleep time and sets its own response repetition count, but the control of the charging switch 135 from the open state to the short-circuit state is omitted. In the electronic circuit 120B shown in the example of FIG. 12, the charging switch 135 and the second power storage unit 110F are omitted, and the first power storage unit 110E serves both as the first power storage unit 110E and the second power storage unit 110F. Since charging of first power storage unit 110E has started without controlling , charging of ignition energy has also started.

In step S256, unit-side control device 110D stores first power storage unit 110E (the power storage unit for circuit operation energy and the power storage unit for ignition energy) based on the detection signal from power storage state detection circuit 137 (see FIG. 12). It is determined whether or not the charging of the battery (which is also used as a battery) has been completed. If the unit-side control device 110D determines that the charging is completed (Yes), the process proceeds to step S257, and if it determines that the charging is not completed (No), the process proceeds to step S258.

The unit-side control device 110D executing the processes of steps S256 and S257, when the designation information included in the received power supply start notification signal CAR matches the designation information stored therein, charge response execution unit 131B, which transmits a charge completion signal including the designation information stored therein via the unit-side transmission antenna when charging to the unit (in this case, first power storage unit 110E) is completed. (see FIG. 12).

In step S259, unit-side control device 110D includes a series of sleep charging operations in power supply start notification signal CAR after charging of the power storage unit (in this case, first power storage unit 110E) is started. Executes the number of times specified in the response repetition count information.

● [Effects of the present invention, etc.]
Using one transmission antenna on the operation side, it is possible to wirelessly instruct ignition from a plurality of wireless ignition units, so there are no long and many wired cables mixed up, and connection errors and stray currents are picked up. Risk can be further reduced. Further, each wireless ignition unit does not contain a battery, and is operated and ignited by the driving energy from the transmission antenna on the operator side immediately before ignition, so that higher safety can be ensured.

In addition, since the wireless ignition unit to be ignited can be designated by the designation information, it is possible to avoid malfunction and interference and ensure higher safety. In addition, by putting the unit-side control device in a sleep state while the wireless ignition unit is being charged, unnecessary power consumption can be suppressed and charging can be performed in a shorter time.

In addition, even if a charge completion signal is not sent to all wireless ignition units specified in the specified information, the process is stopped and ignition is not performed, ensuring higher safety. can do.

Also, the wireless ignition unit 110 can be suitably implemented as the electronic circuit 120 shown in the example of FIG. 11 or the electronic circuit 120B shown in the example of FIG.

By configuring with receiving antennas for the X-axis, Y-axis, and Z-axis, it is possible to efficiently receive the transmitted driving energy or control signal regardless of the direction of the magnetic field. The unit-side receiving antenna 110A is more preferably composed of a three-axis receiving antenna. 117Z only) or a two-axis receiving antenna. In the case of the UHF radio wave system shown in the example of FIG. 1, the unit-side receiving antenna 110A is configured by a planar antenna (for example, a rectenna). not a thing
