However, it is assumed that the system includes a terminal device that does not have an RTC and cannot implement the communication function. In this case, event information including time information cannot be collected from at least some of the plurality of terminal devices included in the system. For this reason, there is a problem that the event occurrence times in the terminal devices may not be compared based on the event information collected from the plurality of terminal devices.

  An object of the present invention is to provide an information collection system, an information collection method, and a terminal device that can collect event information of events that occur in a plurality of terminal devices and specify the occurrence time of each event. .

  An information collection system according to a first aspect of the present invention is an information collection system including a terminal device and a server that can communicate with each other, and the terminal device is device time information indicating a device time that is a time in the terminal device.

A first storage unit that associates the event identification information, the device identification information, and the first device time information and stores them in a first storage unit; and the device identification information received by the first reception unit; Second device time information and second storage means for associating and storing the first clock time information in a second storage unit, wherein the first clock time information is the event identification by the first receiving means. It is the clock time information corresponding to the information reception timing.

  According to the first aspect, when an event occurs, the terminal device has event identification information of the event that has occurred, device identification information of the terminal device, first device time information corresponding to the event occurrence timing, and event identification information. The second device time information corresponding to the transmission timing is transmitted to the server. The server associates the event identification information, the device identification information, and the first device time information and stores them in the first storage unit. The server also associates the device identification information, the second device time information, and the first clock time information corresponding to the reception timing of the event identification information, and stores them in the second storage unit. In this case, the server can associate the second device time information corresponding to the transmission timing of the event identification information in the terminal device with the first clock time information corresponding to the reception timing of the event identification information in the server. For this reason, the server can specify the clock time at the time of occurrence of the event from the first device time information corresponding to the event occurrence timing based on the relationship between the second device time information and the first clock time information. Therefore, the server can specify the clock time when an event occurs in each terminal device, even if each terminal device individually stores the device time information.

  In the first aspect, the server identifies a target terminal device in a second receiving unit that receives a browsing request including device specifying information that can specify the terminal device from a request source device, and the first storage unit. A first acquisition unit configured to acquire the event identification information and the first device time information stored in association with the device identification information, wherein the target terminal device is received by the second reception unit; The terminal device specified by the device specifying information included in the browsing request, and the second device time information stored in the second storage unit in association with the device identification information for identifying the target terminal device And based on the first clock time information, the first device time information acquired by the first acquisition means is identified by the event identification information. Conversion means for converting to second clock time information indicating the clock time when the event occurred, the event identification information acquired by the first acquisition means, and the second clock time information converted by the conversion means You may provide the 2nd transmission means to transmit to the said request origin apparatus. In this case, for example, a client that can communicate with the server can browse the event that occurred in the terminal device and the clock time at which the event occurred by sending a browse request to the server. That is, the client can browse the clock time when an event occurs in the terminal device even when the terminal device cannot directly acquire the clock time.

  In the first aspect, the server obtains the clock time information by first determination means for determining whether or not processing for changing the clock time information stored in the clock time storage unit has been executed, and the first determination means. When it is determined that the process to be changed is performed, a correction corresponding to the difference between the clock time before change indicated by the clock time information before change and the clock time after change indicated by the clock time information after change is performed. And a first correction unit that performs the first clock time information stored in the second storage unit. In this case, the server corrects the first clock time information stored in the second storage unit when the process of changing the clock time information is executed. For this reason, the server can specify the clock time at which the event occurred from the first device time information based on the relationship between the corrected second device time information and the first clock time information. Therefore, even when the process of changing the clock time information is executed, the server can accurately specify the clock time at which the event occurred based on the changed clock time information.

  In the first aspect, the server determines whether the latest event identification information stored in the first storage unit indicates a power-off operation of the terminal device in response to reception by the first receiving unit. 2 determining means and the second determining means, when it is determined that the latest event identification information indicates the power-off operation, the event identification information received by the first receiving means, the terminal device Second acquisition means for acquiring start information indicating a power-on operation of the first device and the first device time information corresponding to the generation timing of the start information, and the generation timing of the start information acquired by the second acquisition means The first device time information corresponding to the time, the second device time information received by the first receiving means, and the clock time corresponding to the reception timing of the activation information Based on the information, calculation means for calculating start clock time information which is the clock time information corresponding to the generation timing of the start information, the start clock time information calculated by the calculation means, and the second memory A second correction unit that corrects the first apparatus time information stored in the first storage unit based on a difference from the first clock time information stored in the unit. When the terminal device is turned off and then turned on, the device time is not updated while the power is off. On the other hand, the server calculates startup clock time information and corrects the first device time information based on the calculated startup clock time information and the first clock time information. Thus, the server can specify the clock time at which the event has occurred even when there is a period in which the device time is not updated in the terminal device.

  In the first aspect, the first transmission unit may transmit the collection target information at any timing in a predetermined cycle. In this case, when a plurality of events occur within a predetermined period, the terminal device can transmit information corresponding to the plurality of events to the server at the same timing. For this reason, the terminal device can suppress the transmission frequency of information compared with the case where information is transmitted to the server each time an event occurs.

Among the second device time information, the latest second device time information, the device identification information, and the first clock time information may be associated and stored in the second storage unit. In this case, when the server repeatedly receives information from the terminal device, the server updates the second device time information stored in the second storage unit with the latest second device time information. Further, the server updates the first clock time information stored in the second storage unit with the clock time information acquired from the clock time storage unit at the reception timing of the latest information. Thereby, the server can specify the clock time when the event occurs in each terminal device based on the latest second device time information and the first clock time information.

The device identification information indicates an identifier for identifying each sewing machine 3. The transmission cycle indicates a transmission interval in the case where collection target information described later is periodically transmitted to the server 2. The master device time information is a counter variable indicating the time in the sewing machine 3 (hereinafter referred to as “device time”). The apparatus time is, for example, a cumulative energization time counted up with the factory shipment time of the sewing machine 3 as “0”. The device time indicated by the master device time information is periodically and repeatedly updated at a predetermined time interval (1 second). Hereinafter, the identifier indicated by the device identification information of the master table 34A is referred to as “device identifier of the master table 34A”.

When an event occurs, the CPU 31 acquires master device time information from the master table 34A. The CPU 31 associates the acquired master device time information with the event identification information of the event that has occurred as the first device time information, and stores it in the third table 33A as the event history information.

  Hereinafter, the identifier indicated by the event identification information in the third table 33A is referred to as “event identifier in the third table 33A”. The device time indicated by the first device time information in the third table 33A is rephrased as “first device time in the third table 33A”. When specifically describing the contents of the event history information, it is expressed as “event identifier / first device time”.

  Although details will be described later, the CPU 31 transmits the collection target information to be transmitted to the server 2 based on the event history information stored in the third table 33 </ b> A in the transmission area 521 of the storage unit 52 of the removable medium 5.

The CPU 31 collects the collection target information 341 including the event history information (“sewing start / 300010”, “sewing end / 300030”, “temporary stop / 300050”) stored in the third table 33A in the storage unit 52 of the removable medium 5. Generated in the transmission area 521. The CPU 31 sets the file identifier “11111 — 300060” including the device identifier “11111” and the master device time (second device time) “300060” of the master table 34A in the collection target information 341. The control unit 53 of the removable medium 5 transmits the collection target data generated in the transmission area 521 of the storage unit 52 to the server 2.

  Information stored in the storage unit 24 of the server 2 will be described. Master clock time information is stored in the master table 24A. The master clock time information is information indicating the current time (hour, minute, second, hereinafter referred to as “clock time”).

Hereinafter, the clock time indicated by the master clock time information of the master table 24A is referred to as “master clock time of the master table 24A”.

  Note that the CPU 21 executes a time management function as one of the functions of the OS. The time management function periodically communicates with an NPT server (not shown) connected to the network 8 and periodically acquires standard time information indicating the standard time. The CPU 21 stores the acquired standard time information in the storage unit 24. Although details will be described later, the CPU 21 executes processing for setting the master clock time of the master table 24A to the standard time (server third processing, see FIG. 10). That is, after the master clock time in the master table 24A is set to the standard time, the CPU 21 updates the master clock time in a cycle of 1 second until the next master clock time is set to the standard time.

  In the first table 24B and the second table 24C, various information included in the received collection target information 341 when the collection target information 341 transmitted from the sewing machine 3 is received by the server 2 is stored. In the first table 24B, device identification information and event history information (event identification information and first device time information) are stored in association with each other. As the device identification information, information indicating the device identifier portion of the received collection target information file name is stored. As event history information, event history information included in the received collection target information is stored. Hereinafter, the device identifier indicated by the device identification information of the first table 24B, the clock time indicated by the first device time information, and the identifier indicated by the event identification information are respectively referred to as “device identifier of the first table 24B”, In other words, “the first clock time of the first table 24B” and “the event identifier of the first table 24B”.

  In the second table 24C, device identification information, second device time information, and first clock time information are stored in association with each other. As the device identification information and the second device time information, information indicating the device identifier and the second device time portion of the received file name of the collection target information is stored. The first clock time information indicates a clock time corresponding to the reception timing of the collection target information. As the first clock time information, master clock time information acquired from the master table 24A when the collection target information is received is stored. Hereinafter, the device identifier indicated by the device identification information in the second table 24C, the device time indicated by the second device time information, and the clock time indicated by the first clock time information are respectively referred to as “device of the second table 24C”. In other words, “identifier”, “second device time in second table 24C”, and “first clock time in second table 24C”.

  For example, FIG. 2 illustrates a case where the collection target information 341 transmitted from the removable medium 5 is received by the server 2 when the master clock time of the master table 24A is “10:31:03”. The CPU 21 extracts the device identifier portion “11111” from the file name of the received collection target information. The CPU 21 associates the device identification information indicating the extracted device identifier with the event history information (“sewing start / 300010”, “sewing end / 300030”, “temporary stop / 300050”) included in the collection target information, respectively. One table is stored in the table 24B. The CPU 21 extracts the second device time portion “300060” from the file name of the received collection target information. The CPU 21 associates the device identification information indicating the extracted device identifier and the second device time information indicating the extracted second device time, and stores them in the second table 24C. The CPU 21 acquires the master clock time “10:31:03” of the master table 24A. The CPU 21 stores the first clock time information indicating the acquired master clock time in the second table 24C in further association with the device identification information and the second device time information.

  In FIG. 2, only event history information (device time information and event identification information) associated with the device identification information of the device identifier “11111” is stored in the first table 24B. Further, only the second device time information and the first clock time information associated with the device identification information of the device identifier “11111” are stored in the second table 24C. On the other hand, the server 2 may receive the collection target information transmitted from the sewing machine 3 different from the sewing machine 3 whose device identification information is “11111”. In this case, first device time information and event identification information associated with device identification information different from the device identifier “11111” are stored in the first table 24B. Further, second device time information and first clock time information associated with device identification information different from the device identifier “11111” are stored in the second table 24C.

<Sewing machine main processing>
The sewing machine main process will be described with reference to FIGS. When the operation of turning on the power of the sewing machine 3 is performed via the operation unit 38, the CPU 31 starts the sewing machine main process by reading and executing the program stored in the storage unit 34. The sewing machine main process is executed until an operation for turning off the power of the sewing machine 3 is performed via the operation unit 38.

  As shown in FIG. 3, the CPU 31 acquires the master device time of the master table 34A. The CPU 31 associates the first device time information indicating the acquired master device time with the event identification information indicating the power-on identifier, and stores it in the third table 33A (S1).

  The CPU 31 starts updating the master device time in the master table 34A (S11). Thereafter, during execution of the sewing machine main process, the CPU 31 repeats a process (not shown) in which 1 is added to the master device time at a cycle of 1 second. The sewing machine main process is started each time the sewing machine 3 is turned on. For this reason, at the start of the sewing machine main process, the master device time in the master table 34A is updated by the previously executed sewing machine main process and becomes an arbitrary value.

  The CPU 21 determines whether the occurrence of an event has been detected (S13). For example, the CPU 21 determines that the occurrence of sewing start and sewing end events has been detected in response to the rotation start and end of the upper shaft motor 36A and the cloth feed motor 36B. For example, the CPU 21 determines that a power-off event has occurred in response to a power-off operation on the operation unit 38. When it is determined that the occurrence of an event has not been detected (S13: NO), the CPU 31 advances the process to S19 (described later). When it is determined that the occurrence of an event has been detected (S13: YES), the CPU 31 advances the process to S15. The CPU 31 acquires the master device time of the master table 34A. The CPU 31 associates the first device time information indicating the acquired master device time with the event identification information indicating the identifier of the event that has occurred, and stores it in the third table 33A (S15). The CPU 31 advances the process to S17.

  The CPU 31 determines whether the event detected by the process of S15 is an event for turning off the power of the sewing machine 3 (S17). When it is determined that the event is an event for turning off the power of the sewing machine 3 (S17: YES), the CPU 31 advances the process to S21 (described later). When it is determined that the event is not an event for turning off the power of the sewing machine 3 (S17: NO), the CPU 31 advances the process to S19. The CPU 31 determines whether or not a time corresponding to the transmission cycle of the master table 34A has elapsed since the collection target information was transmitted by the process of S25 described later (S19). When it is determined that the time corresponding to the transmission cycle has not elapsed (S19: NO), the CPU 31 returns the process to S13. When it is determined that the time corresponding to the transmission cycle has elapsed (S19: YES), the CPU 31 advances the process to S21. When the process of S19 is first executed after the sewing machine main process is started, it is determined that the time corresponding to the transmission cycle has elapsed.

  The CPU 31 acquires event history information (event identification information and first device time information) stored in the third table 33A (S21). The CPU 31 acquires the device identifier of the master table 34A. The CPU 31 acquires the master device time of the master table 34A as the second device time (S23). The CPU 31 generates collection target information including the event history information acquired by the process of S21 in the transmission area 521 of the storage unit 52 of the removable medium 5 (S25). The CPU 31 sets the name including the device identifier and the second device time acquired by the processing of S23 as the file name of the generated collection target information (S25). As a result, the control unit 53 of the removable medium 5 transmits the collection target information stored in the transmission area 521 of the storage unit 52 and the retransmission area 522 described later to the server 2 that is a device having the set address information. . The CPU 31 deletes the information stored in the third table 33A (S29). The CPU 31 advances the process to S51 (see FIG. 4).

  If the device identification information and the event history information are not stored in the third table 33A, that is, if no event has occurred after transmission of the collection target information, the CPU 31 collects the collection target information that does not include the event history information. Is generated. The generated collection target information is empty collection target information in which a file name including the device identifier and the second device time is set.

  When the server 2 receives the collection target information transmitted from the sewing machine 3, the CPU 21 of the server 2 sends reception response information (ACK) for notifying that the collection target information has been received to the removable medium 5. Send back. In response to receiving the ACK from the server 2, the control unit 53 of the removable media 5 stores the ACK in the reception area of the storage unit 52 and transmits a notification signal to the sewing machine 3.

  The CPU 31 determines whether a notification signal output from the control unit 53 of the removable medium 5 has been detected. When the notification signal is detected, the CPU 31 further determines whether ACK is stored in the reception area of the storage unit 52 of the removable medium 5. CPU31 determines whether ACK is memorize | stored in the receiving area of the memory | storage part 52 within a predetermined period, after collection object information is transmitted to the server 2 by the process of S25 (refer FIG. 3). When ACK is stored within a predetermined period, the CPU 31 determines that the collection target information has been successfully transmitted (S51: YES). On the other hand, when the ACK is not stored in the reception area of the storage unit 52 within the predetermined period, the CPU 31 determines that the collection target information has not been successfully transmitted (that is, failed) (S51: NO).

  When it is determined that the collection target information has been successfully transmitted (S51: YES), the CPU 31 deletes the collection target information stored in the transmission area 521 of the storage unit 52 of the removable medium 5 (S53). CPU31 advances a process to S57. On the other hand, when it is determined that transmission of the collection target information has failed (S51: NO), the CPU 31 moves the collection target information stored in the transmission area 521 of the storage unit 52 of the removable medium 5 to the retransmission area 522. (S55). CPU31 advances a process to S57.

  CPU31 determines whether the event detected by the process of S15 (refer FIG. 3) is an event which turns off the power supply of the sewing machine 3 (S57). When it is determined that the event is an event for turning off the power (S57: YES), the CPU 31 ends the sewing machine main process. In this case, the collection target information transmitted by the processing of S25 includes event history information including power-off event identification information. CPU31 returns processing to S13 (refer FIG. 3), when it determines with it not being an event which turns off a power supply (S57: NO).

  For example, FIG. 2 illustrates a case where transmission of the collection target information 341 (file name “11111_300060”) fails (S51: NO). In this case, as shown in FIG. 5, the collection target information 341 is moved from the transmission area 521 to the retransmission area 522 in the storage unit 52 of the removable medium 5 (S55). Thereafter, a case where event history information (sewing start / 300075, sewing end / 300105) is added to the third table 33A is illustrated. In this case, at the timing when the master device time information of the master table 34A becomes “300120” (S19: YES), the collection target information 342 including the event history information stored in the third table 33A (file name “11111_300120”) Is generated in the transmission area 521 of the storage unit 52 of the removable medium 5 (S25). Since the collection target information 342 is stored in the retransmission area 522 of the storage unit 52, the collection target information 341 and 342 is transmitted to the server 2 (S25).

<Server processing>
6, 9, and 10, processing executed by the CPU 21 of the server 2 (server first processing (see FIG. 6), server second processing (see FIG. 9), server third processing (see FIG. 10). )). When an operation to turn on the power of the server 2 is performed, the CPU 21 reads and executes the program stored in the storage unit 24 to start the server first process to the server third process. The server first process to the server third process are executed in parallel. Note that the CPU 21 updates the master clock time in the master table 24A at a cycle of 1 second by a process (not shown) while the server 2 is powered on.

<Server first process>
The server first process will be described with reference to FIG. The CPU 21 determines whether the collection target information transmitted from the sewing machine 3 has been received (S61). When it is determined that the collection target information has not been received (S61: NO), the CPU 21 returns the process to S61. The CPU 21 continues to determine whether the collection target information has been received. When it is determined that the collection target information has been received (S61: YES), the CPU 21 advances the process to S63.

  In the removable medium 5, when the collection target information is stored in the transmission area 521 and the retransmission area 522 of the storage unit 52, a plurality of collection target information is transmitted to the server 2 by the process of S25 (see FIG. 5). . In this case, the CPU 21 determines that a plurality of collection target information has been received by the process of S61.

  The CPU 21 acquires the second device time included in the file name of the received collection target information (S63). When it is determined that the plurality of collection target information has been received by the process of S61, the CPU 21 has the largest value among the second device times acquired from the respective file names of the plurality of collection target information, that is, the latest The second device time is acquired (S63). In the sewing machine 3, the master device time of the master table 34A is incremented by 1 every 1 second. The second device time is the first transmission cycle after the event occurs, and the master when the collection target information corresponding to the occurred event is transmitted from the sewing machine 3 (hereinafter referred to as “first transmitted”). Corresponds to the device time. For this reason, the latest second apparatus time is acquired from the file name of the latest collection target information at the timing of the first transmission among the received collection target information.

  When the received collection target information is one, the second device time included in the file name of the collection target information corresponds to the latest second device time. The collection target information in which the latest second device time is set as a part of the file name is referred to as “latest collection target information”.

  The CPU 21 acquires the master clock time of the master table 24A (S65). The CPU 21 acquires a device identifier included in the file name of the latest collection target information. Hereinafter, of the event history information of the first table 24B, the device identification information indicating the device identifier acquired from the file name of the latest collection target information is referred to as “target device identification information”. The event history information associated with the target device identification information is referred to as “target event history information”.

  The CPU 21 selects target event history information from the first table 24B. The CPU 21 selects the largest value among the selected target event history information, that is, the event identification information associated with the latest first device time information. When event history information is stored in the first table 24B in the order of occurrence of events, the latest event identification information corresponds to the event identification information included in the last event history information. The CPU 21 determines whether the latest event identification information indicates that the power is off (S67). When it is determined that the latest event identification information indicates other than power-off (S67: NO), the CPU 21 advances the process to S79.

  The CPU 21 associates the acquired target device identification information with the second device time information indicating the latest second device time acquired by the process of S63, and stores it in the second table 24C (S79). The CPU 21 further associates the first clock time information indicating the master clock time acquired by the process of S65 and stores it in the second table 24C (S79). When the target device identification information is already stored in the second table 24C, the CPU 21 indicates the latest second device time acquired by the processing of S63 in the stored target device identification information. The second table 24C is updated by associating the time information and the first clock time information indicating the master clock time acquired by the process of S65 (S79). CPU21 advances a process to S81.

  CPU21 selects the collection object information received by the process of S61 one by one. The CPU 21 stores the event history information included in the selected collection target information in the first table 24B in association with the target device identification information (S81). The CPU 21 determines whether all the collection target information received by the process of S61 has been selected (S83). When it is determined that the collection target information that has not been selected remains (S83: NO), the CPU 21 returns the process to S81. The CPU 21 further selects any collection target information that has not been selected, and repeats the process of S81. CPU21 returns a process to S61, when it determines with all the received collection object information having been selected (S83: YES).

  For example, as illustrated in FIG. 5, a case where collection target information 341 (file name “11111_300060”) and 342 (file name “11111_300120”) is transmitted from the removable medium 5 is illustrated. In this case, the CPU 21 acquires second device time information indicating the latest second device time “300120” (S63). The CPU 21 acquires the master clock time “10:32:02” of the master table 24A (S65).

  The CPU 21 determines that the latest event identification information among the target event history information in the first table 24B does not indicate a power-off event (S67: NO). The CPU 21 sets the target device identification information “11111”, the second device time information indicating the latest second device time “300120” acquired by the processing of S63, and the master clock time “10: acquired by the processing of S65. The first clock time information indicating “32:02” is associated and stored in the second table 24C (S79).

  The CPU 21 selects the collection target information 341 and associates the target device identification information (“11111”) with each of the event history information (sewing start / 300010, sewing end / 300030, temporary stop / 300050), and the first table. 24B is stored (S81). Next, the CPU 21 selects the collection target information 342, associates the target device identification information (“11111”) with each of the event history information (sewing start / 300075, sewing end / 300105), and stores them in the first table 24B. (S81).

  On the other hand, as shown in FIG. 6, when it is determined that the latest event identification information indicates that the power is off (S67: YES), the CPU 21 advances the process to S69. The CPU 21 extracts event identification information indicating the power-on identifier from the event history information included in all the collection target information received by the process of S61. The CPU 21 acquires first device time information associated with the extracted event identification information (S69). The CPU 21 calculates the clock time when the power-on event occurs as follows (S71).

Hereinafter, the latest second device time acquired by the process of S63 is referred to as “Ct (on)”. Ct (on) corresponds to the apparatus time when the collection target information including event identification information indicating the power-on identifier is transmitted from the sewing machine 3. The master clock time acquired by the process of S65 is expressed as “Tr (on)”. Tr (on) corresponds to the clock time when the collection target information including the event identification information indicating the power-on identifier is received. The first device time indicated by the first device time information acquired by the process of S69 is referred to as “Ce (on)”. Ce (on) corresponds to the apparatus time when a power-on event occurs in the sewing machine 3. The clock time when the power-on event occurs is expressed as “Te (on)”. In this case, Te (on) is calculated by the following equation (1).
Te (on) = Tr (on) − (Ct (on) −Ce (on)) (1)

  The CPU 21 acquires the first clock time associated with the target device identification information in the second table 24C (S73). The CPU 21 calculates the apparatus time indicating the time elapsed from when the power source of the sewing machine 3 is turned off until it is turned on (S75).

Hereinafter, the first clock time acquired by the process of S73 will be referred to as Tr (off). Tr (off) indicates the clock time when the collection target information including event identification information indicating the power-off identifier is received. The device time indicating the time elapsed from when the power of the sewing machine 3 is turned off to when it is turned on is denoted as C (off-on). In this case, C (off-on) is calculated by the following equation (2).
C (off-on) = Te (on) -Tr (off) (2)

  The CPU 21 subtracts the calculated C (off-on) from the first device time of the target event history information in the first table 24B. Thereby, the CPU 21 updates the first device time information of the target event history information (S77). CPU21 advances a process to S79. A description of the processing of S79, S81, and S83 is omitted.

  A specific example will be described with reference to FIGS. The case where the collection target information 343 (file name “11111_300060”) is transmitted from the sewing machine 3 is illustrated. The collection target information 343 includes event identification information indicating a power-on identifier. The CPU 21 acquires “300060” (= Ct (on)) as the latest second device time (S63). The CPU 21 acquires “10:31:03” (= Tt (on)) as the master clock time of the master table 24A (S65).

The CPU 21 determines that the latest event identification information in the target event history information of the first table 24B indicates that the power is off (S67: YES). The CPU 21 acquires first device time information (“300005”) (= Ce (on)) associated with the power-on event identification information from the event history information included in the collection target information 343 (S69). The CPU 21 calculates Te (on) as follows based on the equation (1) (S71).
Te (on) = “10:31:03” − (300060-300005)
= "10:31:03" -55 = "10:30:08"

The CPU 21 acquires the first clock time “9:31:03” (= Tr (off)) associated with the target device identification information (“11111”) in the second table 24C. The CPU 21 calculates C (off-on) based on the equation (2) as follows (S73).
C (off-on) = “10:30:08” − “9:31:03”
= 3605 (= "01:00:05")

  The CPU 21 subtracts the calculated “3605” from the first device times “298410”, “298500”, “300000” of the target event history information in the first table 24B. Thereby, as shown in FIG. 8, the CPU 21 updates the first device time of the target event history information to “294805”, “294895”, and “296395”, respectively (S77).

  The CPU 21 sets the target device identification information “11111”, the latest second device time “300060” acquired by the processing of S63, and the first clock time “10:31:03” acquired by the processing of S65. Is stored in the second table 24C (S79). Further, the CPU 21 associates the event history information (power on / 300005, sewing start / 300010, sewing end / 300030) included in the received collection target information with the device identification information (111111), respectively, in the first table. 24B is stored (S81).

<Server second process>
The server second process will be described with reference to FIG. CPU21 determines whether the browsing request information transmitted from PC6 was received via the network 8 (S91). The browsing request information is information for requesting browsing of the event history information stored in the server 2. CPU21 returns a process to S91, when it determines with not having received browsing request information (S91: NO). The CPU 21 continuously monitors the reception of browsing request information.

  When the user of the PC 6 inputs an instruction to the PC 6 to request browsing of event history information related to an event that occurred in the desired sewing machine 3, a CPU (not shown) of the PC 6 sends the browsing request information to the server 2 via the network 8. Send. The browsing request information includes information (hereinafter referred to as “device specifying information”) that can specify the sewing machine 3 for which browsing of the event history information is desired by the user. The device specifying information is, for example, device type information (see FIG. 2) indicating the type of each sewing machine 3, group identification information for identifying a group in which the sewing machine 3 is divided into a plurality of pieces, and the like. If it is determined that the browsing request information has been received via the network 8 (S91: YES), the CPU 21 of the server 2 advances the process to S93.

  CPU21 acquires the apparatus specific information contained in the received browsing request information (S93). CPU21 specifies the apparatus identification information of the sewing machine 3 specified based on the acquired apparatus specific information (S95). Hereinafter, the apparatus identification information specified by the process of S95 is referred to as “target apparatus identification information”, and the same paraphrase as in the case of the first server process is performed. The device time indicated by the first device time information included in the target event history information and the identifier indicated by the event identification information are respectively represented as “first device time of target event history information” and “event of target event history information”. In other words, “identifier”. In the second table 24C, the second device time and the first clock time associated with the target device identification information are referred to as “target second device time” and “target first clock time”, respectively.

  The CPU 21 acquires the target second device time and the target first clock time from the second table 24C (S97). The CPU 21 acquires the first device time of the target event history information from the first table 24B (S99). CPU21 selects the 1st apparatus time acquired by the process of S99 one by one. The CPU 21 converts the selected first device time into the second clock time as follows based on the target second device time and the target first clock time acquired by the process of S97 (S101).

Hereinafter, the target second device time acquired by the process of S97 is expressed as “Ct”, and the target first clock time is expressed as “Tr”. The first device time selected from the target event history information acquired by the process of S99 is denoted as “Ce”. The second clock time is expressed as “Te”. In this case, Te is calculated by the following equation (3).
Te = Tr− (Ct−Ce) (3)
The CPU 21 associates the event identification information associated with the first device time selected in the target event history information with the second clock time information indicating the calculated Te (second clock time), and browse response information. Is stored in the RAM 23.

  The CPU 21 determines whether the conversion by the process of S101 has been executed for all the first device times of the target event history information (S103). CPU21 returns a process to S101, when it determines with the 1st apparatus time not converted by the process of S101 remaining in object event history information (S103: NO). The CPU 21 selects, from the target event history information, the first device time at which conversion by the process of S101 has not been executed, and repeats the process of S101. If it is determined that all of the first device time of the target event history information has been converted by the process of S101 (S103: YES), the CPU 21 advances the process to S105. CPU21 transmits the browsing response information memorize | stored in RAM23 to PC6 which transmitted browsing request information (S105). The CPU 21 returns the process to S91.

For example, in FIG. 5, a case where browsing request information including device specifying information specifying device identification information of the device identifier “11111” is transmitted from the PC 6 and received by the server 2 (S91: YES) is illustrated. The CPU 21 specifies target device identification information (“11111”). The CPU 21 acquires the target second device time “300120” (= Ct) and the target first clock time “10:32:02” (= Tr) (S97). The CPU 21 sets the first device time (“300010” (sewing start), “300030” (sewing end), “300050” (sewing start), “300075” (sewing end), “300105” (temporary) of the target event history information. (Stop) (= Ce)) is acquired (S99). The CPU 21 calculates the second clock time as follows by applying the equation (3) (S101).
“10:32:02”-(300120-300010)
= "10:32:02" -110 = "10:30:12" (sewing start)
“10:32:02”-(300120-300030)
= "10:32:02" -90 = "10:30:32" (sewing complete)
“10:32:02”-(300120-300050)
= "10:32:02" -70 = "10:30:52" (sewing start)
“10:32:02”-(300120-300075)
= "10:32:02" -45 = "10:31:17" (sewing start)
“10:32:02”-(300120-300105)
= "10:32:02" -15 = "10:31:47" (pause)
The CPU 21 transmits browsing response information including event identification information and second clock time information to the PC 6 that has transmitted the browsing request information (S105).

<Server third process>
The server third process will be described with reference to FIG. The CPU 21 determines at regular intervals whether the standard time indicated by the standard time information stored in the storage unit 24 matches the master clock time in the master table 24A. When the standard time matches the master clock time, the CPU 21 determines that the master clock time information does not need to be changed (S111: NO). In this case, the CPU 21 returns the process to S111. When the standard time and the master clock time are different, the CPU 21 determines that the master clock time information needs to be changed (S111: YES). In this case, the CPU 21 advances the process to S113.

  The CPU 21 acquires the standard time indicated by the standard time information stored in the storage unit 24 as the changed clock time (S113). The CPU 21 acquires the master clock time of the master table 24A as the pre-change clock time. The CPU 21 calculates a correction value by subtracting the pre-change clock time from the acquired post-change clock time. The CPU 21 corrects the first clock time in the second table 24C with the calculated correction value as follows (S115).

Hereinafter, the clock time before change is expressed as “Tm”, and the clock time after change is expressed as “Ts”. The first clock time before correction in the second table 24C is expressed as “Tb”, and the corrected first clock time is expressed as “Ta”. In this case, Ca is converted by the following equation (4).
Ta = Tb + (Ts−Tm) (4)

  The CPU 21 changes the master clock time (pre-change clock time) of the master table 24A to the changed clock time, and updates the master clock time information (S117). CPU21 returns a process to S111.

  The process of S115 will be specifically described. As shown in FIG. 2, the master clock time (clock time before conversion) of the master table 24A is “10:31:03” (= Tm), and the standard time (clock time after conversion) is “11:31:03. ”(= Ts). In this case, Ts−Tm (“11:31:03” − “10:31:03”) is calculated as “1:00:00”. Accordingly, the first clock time “10:31:03” in the second table 24C is corrected to “11:31:03” obtained by adding “10:00:00” (S115).

  In FIG. 2, since only the first clock time information associated with the device identification information (“11111”) is stored in the second table 24C, only one first clock time information to be corrected is included. became. On the other hand, when a plurality of first clock time information associated with a plurality of device identification information is stored in the second table 24C, all the first clock time information is to be corrected.

<Main functions and effects of this embodiment>
As described above, in the information collection system 1, when an event occurs (S13: YES), the CPU 31 of the sewing machine 3 collects information to be collected (event identification information, device identification information, first device time information, and first information). 2 device time information) is transmitted to the server 2 (S25). The CPU 21 of the server 2 receives the collection target information (S61). The CPU 21 associates the event identification information, the device identification information, and the first device time information and stores them in the first table 24B (S81). Further, the CPU 21 associates the device identification information, the second device time information, and the first clock time information corresponding to the reception timing of the event identification information, and stores them in the second table 24C (S79). In this case, the CPU 21 can associate the second device time information corresponding to the transmission timing of the collection target information in the sewing machine 3 with the first clock time information corresponding to the reception timing of the collection target information in the server 2. Therefore, the CPU 21 can specify the clock time at which the event occurred from the first device time information corresponding to the event occurrence timing based on the relationship between the second device time information and the first clock time information. Therefore, the server can specify the clock time at which an event relating to the sewing process has occurred in each sewing machine 3 even when each sewing machine 3 individually stores the apparatus time information.

  When the CPU 21 receives the browsing request information (S91: YES), the CPU 21 converts the first device time of the target event history information into the second clock time based on the equation (3) (S101). CPU21 transmits the browsing response information containing event identification information and 2nd apparatus time information to PC which transmitted browsing request information (S105). In this case, the PC 6 acquires the event that occurred in the sewing machine 3 and the clock time at which this event occurred by sending the browsing request information to the server 2, and displays them on a display unit (not shown) in association with each other. be able to. For this reason, even when the user of the PC 6 does not have the function of directly acquiring the current time, the user can view the clock time when the event occurs in the sewing machine 3 in association with the event.

  When the master clock time of the master table 24A is different from the standard time (S111: YES), the CPU 21 corrects the master clock time with the standard time and simultaneously corrects the first clock time information stored in the second table 24C. (S115). Therefore, the CPU 21 specifies the clock time at which the event has occurred from the first device time information in the first table 24B based on the relationship between the corrected first clock time information in the second table 24C and the second device time information. it can. Therefore, even when the master clock time is changed, the CPU 21 can accurately specify the clock time at which the event has occurred based on the changed master clock time.

  When the power of the sewing machine 3 is once turned off and then turned on, the master device time is not updated while the power is off. On the other hand, the CPU 21 calculates a device time indicating a time elapsed from when the power source of the sewing machine 3 is turned off based on the equations (1) and (2) (S75). The CPU 21 can correct the first device time by subtracting the calculated device time from the first device time of the target event history information in the first table 24B (S77). Thereby, even when there is a period in which the master device time is not updated in the sewing machine 3, the CPU 21 can accurately specify the clock time at which the event has occurred.

  The CPU 31 of the sewing machine 3 generates collection target information based on the event history information stored in the third table 33A. The CPU 31 sets a file name including the device identifier and the second device time as the file name of the generated collection target information (S25). In this case, the CPU 31 can store the event history information directly related to the generated event in the third table 33A, distinguishing it from the device identifier and the second device time. Further, by setting the device identifier and the second device time as collection target information as a file name, information indicating these can be easily notified to the server 2.

  When it is determined that the time corresponding to the transmission cycle of the master table 34A has elapsed (S19: YES), the CPU 31 transmits the collection target information to the server 2 (S25). Thus, when a plurality of events occur within the transmission cycle, the CPU 31 can transmit the collection target information corresponding to the plurality of events to the server 2 at the same timing. For this reason, CPU31 can suppress the transmission frequency of collection object information compared with the case where collection object information is transmitted to the server 2 whenever an event generate | occur | produces.

  When it is determined that the transmission of the collection target information has failed (S51: NO), the CPU 31 moves the collection target information that has failed to be transmitted from the transmission area 521 of the storage unit 52 of the removable medium 5 to the retransmission area 522 ( S55). The CPU 31 transmits the collection target information stored in the transmission area 521 and the retransmission area 522 of the storage unit 52 to the server 2 in the next transmission cycle (S25). In this case, if the transmission of the collection target information to the server 2 fails, the CPU 31 can execute the retry transmission of the collection target information after a time corresponding to the transmission cycle. Therefore, for example, even when the communication state between the server 2 and the sewing machine 3 temporarily deteriorates, the CPU 31 can transmit the collection target information to the server 2. The retry transmission of the collection target information is executed at any timing in the transmission cycle. For this reason, it can suppress that the transmission frequency of a retry increases according to the collection object information which failed in transmission to the server 2 increasing.

  When it is determined that the plurality of collection target information has been received from the sewing machine 3 (S61: YES), the CPU 21 of the server 2 determines the latest among the second device times acquired from the respective file names of the plurality of collection target information. The second device time is acquired (S63). The CPU 21 associates and stores the acquired information indicating the second device time and the first clock time in the second table 24C. In this case, when the collection target information is repeatedly received from the sewing machine 3, the CPU 21 can update the second device time information stored in the second table 24C with the latest second device time information. Further, the CPU 21 can update the first clock time information stored in the second table 24C with the master clock time information acquired from the master table 24A at the reception timing of the latest collection target information. Therefore, the CPU 21 can accurately specify the clock time at which the event occurred in each sewing machine 3 based on the latest second device time information and the first clock time information.

  When data is written in the transmission area 521 of the storage unit 52, the control unit 53 of the removable medium 5 transmits the collection target information stored in the transmission area 521 and the retransmission area 522 to the server 2. For this reason, the CPU 31 of the sewing machine 3 can transmit the collection target information to the server 2 by writing data in the transmission area 521 of the storage unit 52. In addition, when data is received, the control unit 53 of the removable medium 5 stores the data in the reception area of the storage unit 52. The CPU 31 can receive the data transmitted from the server 2 by reading the data from the reception area of the storage unit 52. In this case, even when the sewing machine 3 itself does not have a communication function, the server 2 can collect collection target information related to an event that has occurred in the sewing machine 3.

<Modification>
The present invention is not limited to the above embodiment, and various modifications can be made. The sewing machine 3 can be changed to another device (for example, a printer, a scanner, a machine tool, etc.) capable of storing the history of events. The sewing machine 3 may incorporate a communication function in advance. For example, the sewing machine 3 may include a communication I / F (LAN card, Wi-Fi communication modem, etc.) that can communicate with the server 2 via the network 8 in advance. In this case, the collection target information is transmitted to the server 2 after being stored in the storage unit 34 or the RAM 33 of the sewing machine 3 without using the removable medium 5.

  It goes without saying that the device that transmits the browsing request information is not limited to the PC 6. For example, the browsing request information may be a tablet terminal, a smartphone, or the like. The device identification information specified by the device specifying information is not limited to one, and may be plural. A correspondence table capable of specifying the device identification information based on the device specifying information may be stored in the storage unit 24 of the server 2. When executing the process of S95, the CPU 21 of the server 2 may refer to the table stored in the storage unit 24 and specify the device identification information based on the device specifying information. The CPU 21 transmits the target event history information, the target second device time information (Ct) acquired by the process of S97, and the target first clock time information (Tr) to the PC 6 that has transmitted the browsing request information. Good. The PC 6 may calculate the second clock time information using the equation (3) based on the received Ct, Tr and the second device time information (Ce) included in the target event history information. The PC 6 may cause the display unit to display the calculated second clock time information together with the corresponding event identification information.

  The server 2 may have a display unit and an operation unit. CPU21 may perform the process of S93-S103 of a server 2nd process, when operation for instruct | indicating the display of event history information is performed via the operation part. The CPU 21 may display a screen indicating the generated browsing response information on the display unit.

  When executing the process of S111, the CPU 21 determines at regular intervals whether the standard time matches the master clock time. On the other hand, for example, the OS may set “1” in the notification flag at the timing when the standard time information is acquired from the NPT server. When “1” is not set in the notification flag, the CPU 21 may determine that the master clock time information does not need to be changed (S111: NO). On the other hand, when “1” is set in the notification flag, the CPU 21 may determine that the master clock time information needs to be changed (S111: YES).

  The CPU 21 is turned on after the power of the sewing machine 3 is turned off based on the first device time associated with the power-on event identification information, the clock time when the power-on event occurs, and the first clock time. The device time indicating the time elapsed until the time was calculated (S75). The CPU 21 updates the first device time of the target event history information based on the calculated device time (S77). On the other hand, for example, when the CPU 21 receives collection target information including event identification information indicating a power-off event from the sewing machine 3, the CPU 21 adds the first device time information in the first table 24B one by one every 1 second. May be executed. When the CPU 21 receives the collection target information including the event identification information indicating the power-on event from the sewing machine 3, the CPU 21 may end the above process.

  The CPU 31 generates collection target information of file names including the device identification information and the second device time (S25). On the other hand, the CPU 31 may generate collection target information including event identification information, first device time information, device identification information, and second device time information. That is, the file name including the device identification information and the second device time information may not be set in the collection target information.

  When it is determined that the transmission cycle has arrived based on the cycle stored in the master table 34A (S19: YES), the CPU 31 transmits the collection target information (S25). On the other hand, the timing at which the collection target information is transmitted may be any transmission cycle after the event has occurred. That is, the CPU 31 does not have to transmit the collection target information in the transmission cycle that comes immediately after the occurrence of the event, and may transmit the collection target information at any timing in the subsequent transmission cycle. Further, the CPU 21 may transmit the collection target information at the timing when the event occurs. Specifically, the CPU 21 may transmit the collection target at the timing when the event occurs each time an event occurs by skipping and executing the processing of S19.

  When it is determined that the transmission of the collection target information has failed (S51: NO), the CPU 31 moves the collection target information from the transmission area 521 to the retransmission area 522 in the storage unit 52 of the removable medium 5 (S55). When the next transmission cycle arrives, the control unit 53 of the removable medium 5 responds to a newly occurring event when the collection target information is stored in the retransmission area 522 of the storage unit 52, and the transmission area The collection target information stored in 521 and the collection target information stored in the retransmission area 522 are transmitted (S25). In contrast, the CPU 31 may transmit common collection target information including event history information included in the collection target information stored in the retransmission area 522 and event history information corresponding to a newly generated event. .

  When it is determined that the transmission of the collection target information has failed (S51: NO), the CPU 31 moves the collection target information stored in the transmission area 521 of the storage unit 52 of the removable medium 5 to the retransmission area 522 ( S55). On the other hand, when it is determined that the transmission of the collection target information has failed, the CPU 31 may leave the collection target information stored in the transmission area 521 in the storage unit 52 of the removable medium 5 as it is. . That is, the retransmission area 522 may not be provided in the storage unit 52 of the removable medium 5. Even in this case, when the next transmission cycle comes, the collection target information stored in the transmission area 521 of the storage unit 52, that is, the collection target information that has failed to be transmitted is transmitted to the server 2. .
