When the power supply control unit 21 determines that the scheduled end time has not elapsed (step S101: No), timer monitoring is performed (step S100), and the scheduled end time has elapsed for each time set by the timer. Whether or not is continued (step S101).

  When the power supply control unit 21 determines that the scheduled end time has elapsed (step S101: Yes), the timer monitoring ends, and then the determination unit 22 confirms whether the sample analysis in the measurement mechanism 40 has ended. (Step S102). When the analysis is not completed (step S102: No), the analysis of the sample is continued (step S103). When the analysis is confirmed to be completed (step S102: Yes), the determination unit 22 outputs the analysis result to the output unit 17. It is confirmed whether it is output by (step S104). When the output of the analysis result has not ended (step S104: No), the analysis result is output (step S105), and when the output of the analysis result has ended (step S104: Yes), the determination unit 22 Further, it is confirmed whether or not the post-analysis cleaning has been completed (step S106). The post-analysis cleaning is cleaning by the cleaning mechanism 12 of the reaction vessel 5. If the post-analysis cleaning is not completed (step S106: No), the post-analysis cleaning of the reaction vessel 5 is performed by the cleaning mechanism 12 (step S107).

  When the post-analysis cleaning has been completed (step S106: Yes), the determination unit 22 acquires the latest access time of the user to the automatic analyzer 1 stored in the storage unit 19 (step S108). The determination unit 22 further determines whether or not a predetermined time has elapsed from the acquired latest access time (step S109). When the determination unit 22 determines that the predetermined time has not elapsed since the latest access time (step S109: No), it waits until the predetermined time has elapsed, and after the determination unit 22 determines that the predetermined time has elapsed since the latest access time ( In step S109: Yes), the output unit 17 outputs that the automatic analyzer 1 is turned off (step S110). By notifying the user of automatic power off, the user is given an opportunity to determine whether or not the power can be turned off. After outputting the power off, it is confirmed whether or not the user has accessed within a predetermined period (step S111). If there is no access (step S111: No), the power control unit 21 turns the automatic analyzer 1 on. Turn off (step S112). When there is a user access (step S111: Yes), the automatic power-off process ends, and the user manually turns off the automatic analyzer 1.

  Since the automatic analyzer 1 according to the first embodiment can automatically power off regardless of whether there is an instruction to the user by performing the above automatic power off process, the witness time required for the power off process of the automatic analyzer 1 is set. It can be greatly shortened. In addition, since the automatic power-off process can be canceled even after the automatic power-off process is started, it is possible to easily cope with the case where an additional analysis process or re-examination occurs.

  Further, as shown in FIG. 3, after completion of post-analysis cleaning is confirmed (step S206: Yes), or after post-analysis cleaning of the reaction vessel 5 is performed by the cleaning mechanism 12 (step S207), automatic A process of automatically turning off the power after a predetermined time required until the power of the analyzer 1 is turned off is exemplified as a modification of the first embodiment. In this modification, after completion of post-analysis cleaning, which is the final step of post-analysis processing, the power supply control unit 21 checks whether or not a predetermined period has elapsed since the post-analysis cleaning (step S208). The automatic analyzer 1 is automatically turned off. Also according to this modification, the automatic analyzer can be turned off without requiring the presence of the user, and the user's restraint time can be greatly reduced.

After being transported to the automatic analyzer 1B by the sample transport system 33 and rotated by the rack rotating mechanism 33e, it is pushed out by an unillustrated push-out unit and is carried to the rack pull-in unit 24B. An information reading device 10B is installed at the entrance of the rack pull-in portion 24B. The information reading device 10B reads the sample information again from the sample information recording medium attached to the sample container 9a, and outputs the read sample information to the central controller 34. . After the rack 9 is transported into the rack pull-in part 24B, the sample is aspirated by the sample dispensing device 20. The specimen is discharged into a reaction container (not shown) accommodated in the reaction table 4, and the reagents in the first reagent container 2 and the second reagent container are respectively transferred to the reaction container by the first reagent dispensing device 6 and the second reagent dispensing device. The sample is dispensed and analyzed in the automatic analyzer 1B. The control unit 15 of the automatic analyzer 1B receives instructions from the central controller 34 to control the operation of the entire automatic analyzer 1B, and receives measurement data including measurement items, measurement results, and the like in the automatic analyzer 1B. 34.

  After the dispensing for the sample in the sample container 9a held in the rack 9 in the automatic analyzer 1B is completed, the rack 9 is returned from the rack pull-in part 24B to the sample transport system 33 and is supplied to the sample loading / unloading port 30. Transported and discharged.

  The central controller 34 is a personal computer that controls the entire automatic analysis system 100, and includes an input unit 16, an output unit 17, a storage unit 19, a sample transport control unit 35, a power supply control unit 21, and a determination unit 22. . The input unit 16 inputs various information including analysis items and the like related to the analysis operation to the automatic analysis system 100. For example, a keyboard or a mouse is used. The output unit 17 outputs automatic power-off of the automatic analyzers 1 </ b> A and 1 </ b> B, and outputs various information such as analysis contents, analysis results, and alarms related to the analysis operation in the automatic analysis system 100. The central control device 34 is a route (pre-processing device and automatic analyzer) for transporting the rack 9 based on rack information and sample information read by an information reader (not shown) installed in the sample loading / unloading port 30. Based on the determination, the sample transport control unit 35 controls the transport of the rack 9 by the sample transport system 33. The storage unit 19 stores the scheduled end time set for each automatic analyzer and the access time of the user to each automatic analyzer. The determination unit 22 determines the end of post-analysis processing of the automatic analyzers 1A and 1B, acquires the latest access time from the storage unit 19, and determines whether a predetermined time has elapsed from the access time. The power supply control unit 21 detects each automatic operation when the scheduled end time stored in the storage unit 19 elapses and the user does not access within a predetermined period from when the output unit 17 outputs power off of each automatic analyzer. Control the analyzer to be turned off individually.

  Next, automatic power-off processing of the automatic analyzer 1 according to the second embodiment will be described with reference to FIGS. FIG. 5 is a display example of the scheduled end time setting screen of the automatic analyzer 1A. FIG. 6 is a flowchart of the automatic power-off process of the automatic analyzers 1A and 1B in the automatic analysis system 100 according to the second embodiment.

  As shown in FIG. 6, in the automatic power-off process of the automatic analysis system 100 according to the second embodiment, first, the power supply control unit 21 first determines the scheduled end time and power-off of each automatic analysis device stored in the storage unit 19. Information is acquired (step S300). The power-off information is information about whether the user has selected standby or power-off on the scheduled end time setting screen shown in FIG. After obtaining the information, the timer is monitored by a timer (not shown) (step S301), and at every predetermined time (step S301: Yes), the power supply control unit 21 checks whether the scheduled end time of each automatic analyzer has elapsed. Processing is performed (step S302). When the power supply control unit 21 determines that the scheduled end time has not elapsed (step S302: No), timer monitoring is performed (step S301), and the scheduled end time has elapsed for each time set by the timer. Whether or not is continued (step S302).

  When the power supply control unit 21 determines that the scheduled end time has passed (step S302: Yes), the power supply control unit 21 controls the automatic analyzer for an unanalyzed sample of the automatic analyzer that is the target of the power-off process. The unit 15 and the sample transport control unit 35 are inquired (step S303). Here, for example, when the scheduled end time of the automatic analyzer 1A has elapsed, the power supply control unit 21 obtains the sample information and analysis information of the sample waiting for dispensing in the rack pull-in unit 24A from the control unit 15 of the automatic analyzer 1A. In addition to the acquisition, the sample transport control unit 35 acquires the sample information of the sample scheduled to be transported to the automatic analyzer 1A. Based on the acquired information, the determination unit 22 determines whether or not the analysis of the automatic analyzer 1A has ended (step S304). If it is determined that the analysis has not been completed (step S304: No), the analysis is continued (step S305). When it is determined that the analysis is completed (step S304: Yes), the determination unit 22 confirms whether the analysis result is output from the output unit 17 (step S306), and the output of the analysis result is not completed. (Step S306: No), the analysis result is output (Step S307). When the output of the analysis result has been completed (step S306: Yes), the determination unit 22 further confirms whether or not the post-analysis cleaning has been completed (step S308). If post-analysis cleaning is not completed (step S308: No), post-analysis cleaning is performed (step S309).

  When the post-analysis cleaning has been completed (step S308: Yes), the power supply control unit 21 checks whether or not the information acquired in step S300 has been selected to be turned off (step S310). If standby is selected (step S310: No), the process proceeds to step S316, and the automatic analyzer 1A enters a standby state as instructed by the user. When the power-off is selected (step S310: Yes), the determination unit 22 acquires the latest access time of the user's automatic analyzer 1A stored in the storage unit 19 (step S311). It is determined whether or not a predetermined time has elapsed since the latest access time (step S312). If the determination unit 22 determines that the predetermined time has not elapsed since the latest access time (step S312: No), the determination unit 22 waits until the predetermined time has elapsed, and after the determination unit 22 determines that the predetermined time has elapsed from the latest access time ( In step S312: Yes, the output unit 17 outputs that the automatic analyzer 1A is turned off (step S313). By notifying the user of automatic power off, the user is given an opportunity to determine whether or not the power can be turned off. By finally giving an opportunity to determine whether or not the power can be turned off, even if the necessity for maintenance, reanalysis, etc. occurs later, it can be easily dealt with. After the output of power off, the power control unit 21 confirms whether or not the user has accessed within a predetermined period (step S314). If there is no access (step S314: No), the power control unit 21 performs automatic analysis. The apparatus 1A is turned off (step S315). When there is a user access (step S314: Yes), the power is turned off manually by the user instead of the automatic power-off process, and the automatic power-off process is performed again after the maintenance and reanalysis processes are completed. Also good.

  Thereafter, the power control unit 21 checks whether or not the power-off process has been completed for all automatic analyzers (step S316), and if the power-off process has not been performed for all automatic analyzers (step S316: No), the process is repeated from step S302 for the automatic analyzer that has not been turned off. When the power-off process is completed for all the automatic analyzers (step S316 :: Yes), the automatic power-off process of the automatic analysis system 100 is terminated.

  Since the automatic analysis system 100 according to the second embodiment can automatically turn off the power of each automatic analyzer individually, the trouble of turning off the power by reciprocating to the installation location of each automatic analyzer can be eliminated. Therefore, the user's restraint time can be shortened. In addition, the scheduled end time can be set for each automatic analyzer considering the operating status, and the power can be automatically turned off from the automatic analyzer after the scheduled end time has elapsed, thus enabling efficient reduction of power consumption. .

(Embodiment 3)
Embodiment 3 is an automatic analysis system 200 including an automatic analyzer that analyzes a plurality of identical analysis items, and a sample transport system that transports a rack that holds a sample container in each of the automatic analyzers, and its power source. Off method. FIG. 7 is a plan view showing a schematic configuration of the automatic analysis system 200 of the third embodiment. The automatic analysis system 200 according to the third embodiment has the same configuration as the automatic analysis system 100 according to the second embodiment, except that the automatic analysis devices 1A and 1B of the automatic analysis system 100 according to the second embodiment are the same type.

  The automatic power-off process of the automatic analysis system 200 according to the third embodiment will be described with reference to FIG. FIG. 8 is a flowchart of the automatic power-off process of the automatic analyzers 1A and 1B in the automatic analysis system 200 according to the third embodiment.

Confirmation (step S403). Here, for example, when the scheduled end time of the automatic analyzer 1A elapses, it is confirmed whether or not the automatic analyzer 1B is in operation (whether the power-off process has ended). When the automatic analyzer 1B is in operation (step S403: Yes), the sample transport control unit 35 stops the sample transport to the automatic analyzer 1A (step S404). Here, if the scheduled end time is set later and there is an active automatic analyzer in the system, the sample is distributed to the automatic analyzer that has the scheduled end time in operation late, The automatic analyzer can be turned off without delaying the set scheduled end time. This enables efficient reduction of power consumption because the number of automated analyzers to be operated can be adjusted by automatic power-off processing when the number of samples analyzed per day varies with time and the amount of processing at each time can be ascertained. Is possible.

  On the other hand, when the automatic analyzer 1B is subjected to the power-off process (step S403: No), the power controller 21 controls the sample analyzer 15A and the sample transport control for the unanalyzed sample in the automatic analyzer 1A. The unit 35 is inquired (step S405). The inquiry is obtained from the control unit 15 of the automatic analyzer 1A, the sample information of the sample waiting to be dispensed in the rack pull-in unit 24A and the analysis status of the automatic analyzer 1A, and transferred from the sample transfer control unit 35 to the automatic analyzer 1A.

Based on the acquired information, the determination unit 22 determines whether or not the analysis of the automatic analyzer 1A is completed (step S406). If it is determined that the analysis has not been completed (step S406: No), the analysis is continued (step S407). Thereafter, the determination unit 22 checks whether or not the analysis result is output from the output unit 17 (step S408). If the output of the analysis result is not completed (step S408: No), the analysis result is output. (Step S409). When the output of the analysis result has been completed (step S408: Yes), the determination unit 22 further confirms whether or not the post-analysis cleaning has been completed (step S410). If post-analysis cleaning is not completed (step S410: No), post-analysis cleaning is performed (step S411).

  When the post-analysis cleaning has been completed (step S410: Yes), the power supply control unit 21 determines whether the information acquired in step S400 is selected to be turned off (step S312). If standby is selected (step S312: No), the process proceeds to step S418, and the automatic analyzer 1A enters a standby state as instructed by the user. When the power-off is selected (step S412: Yes), the determination unit 22 acquires the latest access time of the user to the automatic analyzer 1A stored in the storage unit 19 (step S413). Thereafter, the determination unit 22 determines whether or not a predetermined time has elapsed from the acquired latest access time (step S414). If the predetermined time has not elapsed since the latest access time (step S414: No), the predetermined unit is determined. Wait until the time elapses, and after determining that the predetermined time has elapsed since the latest access time (step S414: Yes), the output unit 17 outputs that the automatic analyzer 1A is turned off (step S415). By notifying the user of automatic power off, the user is given an opportunity to determine whether or not the power can be turned off. After the output of power off, the power control unit 21 checks whether or not the user has accessed within a predetermined period (step S416). If there is no access (step S416: No), the power control unit 21 performs automatic analysis. The apparatus 1A is turned off (step S417). When there is a user access (step S416: Yes), the power is turned off manually by the user instead of the automatic power-off process, and the automatic power-off process is performed again after the maintenance and reanalysis processes are completed. Also good.

  Thereafter, the power control unit 21 checks whether or not the power-off process has been completed for all automatic analyzers (step S418), and if the power-off process has not been performed for all automatic analyzers (step S418: No), the process is repeated from step S402 for the automatic analyzer that has not been turned off. When the power-off process is completed for all the automatic analyzers (step S418 :: Yes), the automatic power-off process of the automatic analysis system 200 ends.

  Since the automatic analysis system 200 according to the third embodiment can automatically turn off the power of each automatic analyzer individually, the trouble of reciprocating operation to the installation location of each automatic analyzer can be eliminated. Not only can the user's restraint time be shortened, but the number of automatic analyzers to be operated can be adjusted by automatic power-off processing when the number of analysis processes per day can be predicted in advance.

The sample information of the sample waiting to be dispensed and the analysis information (number of analysis items) of each sample are acquired, and the time required for dispensing is calculated for each automatic analyzer (step S503). The sample transport control unit 35A controls to stop the transport of the rack 9 to the automatic analyzer having the calculated required dispensing time (step S504). Thereafter, the power supply control unit 21 performs power-off processing of the automatic analyzer 1A and the automatic analyzer 1B in parallel (steps S505 and S506).

  Next, the power-off process of the automatic analyzer 1A will be described with reference to FIG. The determination unit 22 confirms whether or not the analysis is completed in the automatic analyzer 1A (step S600). Here, when the time required for dispensing the sample waiting in the rack pull-in unit 24A of the automatic analyzer 1A is larger than the automatic analyzer 1B, it is confirmed whether or not the analysis of all the samples in the rack pull-in unit 24A is completed. If it is small, in addition to the sample waiting in the rack pull-in part 24A of the automatic analyzer 1A, the automatic analyzer 1A also analyzes the sample not transported in the sample loading / unloading port 30 and the sample transport system 33. As it is done, the end of the analysis is confirmed. When the analysis is not completed (step S600: No), the analysis of the sample is continued (step S601).
