Convert to voice instruction text.
  • the system management unit 1103 transfers the voice data to all the automatic analyzers when the voice instruction text instructs "emergency stop" for all the automatic analyzers in the automatic analysis system (step 903).
  • "emergency stop” as an operation instruction for all the automatic analyzers managed by the management server 601, designation of the device name can be omitted.
  • "emergency stop” is defined as an operation instruction, and the value of that cell is valid regardless of the device state.
  • the system management unit 1103 checks whether or not the automatic analyzer to be operated is specified (step 904). If the device name is not specified, the last operation identifier column 1002 and the last operation date/time column 1003 of the management table 705 are read to find the automatic analyzer operated at the latest date/time by the access source mobile device. If the corresponding mobile device is found, the automatic analyzer is set as a candidate for operation (step 905). As a result, the user can omit the utterance of the name of the automatic analyzer when continuously performing voice input to the same automatic analyzer, thereby improving the user's convenience. At this time, if the last operation date and time is earlier than the current date and time by a certain amount of time or more, it may be considered that there is no continuous voice input, and the automatic analyzer may not be set as an operation target candidate.
  • step 906 it is checked whether the instructed operation can be executed from the equipment status of the automatic analyzer (step 906).
  • the system management unit 1103 obtains the device status of the automatic analyzer from the management table 705, then refers to the determination table to obtain the device status and the cell value corresponding to the operation instruction indicated by the voice instruction text. . If the cell value is valid, go to step 908 . On the other hand, if the cell value is "-" (non-execution), the operation instruction is impossible or meaningless, and there is a possibility that the user has mistakenly specified the automatic analyzer to be operated.
  • the system management unit 1103 acquires the device status of other automatic analyzers from the device status column 1004 of the management table 705, and similarly determines the validity of the operation instruction using the determination table. Since the automatic analyzer whose cell value is valid can execute the operation instruction, there is a possibility that the automatic analyzer is the one intended to be operated by the user. Therefore, for example, if the automatic analyzer for which the cell value is valid is No. 3, the system management unit 1103 recommends through the mobile communication unit 1101 such as "Are you sure you are not mistaken for No. 3?" step 907) and return to step 900;
  • the system management section 1103 checks whether the user has the authority to operate the automatic analyzer (step 908). From the operable mobile device identifier column 1006 of the management table 705, the cell of the relevant automatic analyzer is examined. On the other hand, if the identifier of the access source mobile device is not included, it is determined that there is no operation authority, and the process returns to step 900 . At this time, the mobile communication unit 1101 transmits data indicating that there is no operation authority to the access source mobile device, and the access source mobile device displays a result such as "There is no operation authority for the third device.” Sound output is good.
  • the system management unit 1103 checks whether or not another mobile device 107 has locked the operation target candidate automatic analyzer (step 909). It can be confirmed from the lock status column 1005 of the management table 705 whether or not the candidate automatic analyzer for operation is locked. If the operation target candidate automatic analysis device is unlocked or locked by the access source mobile device itself, it is determined that it is operable and the process proceeds to step 910 . If it is locked by another mobile device, it is determined that the operation is disabled and the process returns to step 900 .
  • the mobile communication unit 1101 transmits data indicating that it is locked by another mobile device to the access source mobile device, and the access source mobile device reads, "Other mobile devices are locked and cannot be operated.” It is recommended to display the results on the screen or output them by voice.
  • the method by which the user locks or unlocks a specific automatic analyzer is explicitly specified by the user, for example, "Unit 1, start locking” or "Unit 1, unlock”. Alternatively, it may be set such that the transfer destination automatic analysis device is locked for a certain period of time from the time when the voice data for a specific voice instruction is transferred to the automatic analysis device.
  • the system management unit 1103 selects the automatic analysis apparatus to be operated in the management table 705. After recording that the lock status is locked by the access source mobile device, the voice data is transferred from the device communication section 1104 to the operation section 102 of the identified automatic analyzer (step 910), and the process returns to step 900.
  • step 902 If no voice data is received from the mobile device 107 in step 902, it is checked whether there is a termination instruction from the administrator of the automatic analysis system (step 911). If there is a termination instruction, this program is terminated, and if there is no termination instruction, the process returns to step 900 .
  • the voice data from the user is transferred from the management server 601 to the automatic analyzer 100, and the voice input processing sequence of the first embodiment is executed for each automatic analyzer 100.
  • flexible voice input processing can be performed by setting the determination table 303 corresponding to the usage situation in the automatic analyzer 100 .
  • the determination table 303 held by the management server 601 in this case, it is assumed that the valid cell of the determination table 303 held by the management server 601 is set with the threshold of the degree of certainty of speech recognition).
  • the voice instruction text recognized by the management server 601 is sent to the automatic analyzer. You may make it transmit. In this case, it is possible to lighten the computational load required for voice input processing in each automatic analyzer.
