Description

Management system and management method 【0001】 The present invention relates to a management system and a management method. 【0002】 Conventionally, as one of the systems for managing the quality of the liquid stored in a tank, for example, a system that measures the residence time of the liquid stored in the tank by timing means and, when this residence time reaches a predetermined time, performs a process of discarding the liquid from the tank by a disposal unit and supplying new liquid from a supply source has been proposed (see, for example, Patent Document 1). 【0003】 Japanese Patent Application Laid-Open No. 2010-197292 【0004】 Here, in the above conventional system, as described above, when the residence time of the liquid stored in the tank reaches a predetermined time, the above process is performed. Therefore, for example, even if the quality of the liquid stored in the tank has not deteriorated, when the residence time reaches a predetermined time, the above process is performed, so there is a risk that the liquid stored in the tank will be wasted. Therefore, there was room for improvement from the viewpoint of improving the efficiency of replacement processes such as the above process. 【0005】 The present invention is for solving the problems in the above prior art, and an object thereof is to provide a management system and a management method capable of improving the efficiency of replacement processes. 【0006】To solve the above-mentioned problems and achieve the objective, the management system described in claim 1 is a management system for managing the quality of a liquid stored in a storage means, comprising: supply means for supplying the liquid from a supplier to the storage means; disposal means for disposing of the liquid stored in the storage means to a disposal site; identification means for identifying the amount of the liquid stored in the storage means used; timing means for timing the dwell time of the liquid in the storage means; determination means for determining whether or not to replace the liquid stored in the storage means with the liquid supplied from the supplier, based on the amount of the liquid used identified by the identification means and the dwell time timing by the timing means; and processing means for performing a replacement process at least once, in which the liquid stored in the storage means is disposed of by the disposal means, and then the liquid is supplied to the storage means by the supply means and stored, based on the determination result of the determination means. 【0007】 The management system according to claim 2 is the management system according to claim 1, wherein the determination means determines whether the amount of liquid used, as determined by the identification means, has reached a predetermined amount after the dwell time measured by the timing means has elapsed for a predetermined time, and the processing means executes the replacement process if it is determined by the determination means that the amount has not reached the predetermined amount. 【0008】 The management system according to claim 3 is the management system according to claim 2, wherein if the processing means determines that the predetermined amount has been reached by the determination means and therefore does not perform the replacement process, the timing means resets and restarts the timing of the dwell time. 【0009】 The management system according to claim 4 is the management system according to any one of claims 1 to 3, wherein the processing means adjusts the number of times the replacement process is performed based on the residence time measured by the timing means and / or the amount of liquid used specified by the identification means. 【0010】The management system according to claim 5 is the management system according to any one of claims 1 to 3, further comprising a temperature measuring means for measuring the ambient temperature around the storage means or the temperature of the liquid stored in the storage means, wherein the processing means adjusts the number of times the replacement process is performed based on the measurement result of the temperature measuring means. 【0011】 The management system according to claim 6 is a management system according to any one of claims 1 to 3, wherein the determination means determines whether the number of times the replacement process has been executed has reached a predetermined number of times within a predetermined period, and the processing means executes the replacement process multiple times if it is determined by the determination means that the predetermined number of times has been reached. 【0012】 The management system according to claim 7 is a management system according to any one of claims 1 to 3, further comprising a quality detection means for detecting the quality of the liquid stored in the storage means, wherein the determination means determines whether or not to replace the liquid stored in the storage means with the liquid supplied from the supply source, based on the detection result of the quality detection means, the amount of liquid used identified by the identification means, and the residence time measured by the timing means. 【0013】 The management system according to claim 8 is the management system according to claim 7, wherein the quality detection means comprises measuring means for measuring the amount of light emitted from the liquid dispensed into a reaction vessel located at a predetermined position, and quality identification means for identifying the quality of the liquid based on the amount of light emitted from the liquid measured by the measuring means. 【0014】The management method described in claim 9 is a management method for managing the quality of a liquid stored in a storage means using a management system, the management system comprising: supply means for supplying the liquid from a source to the storage means; disposal means for disposing of the liquid stored in the storage means to a disposal site; identification means for identifying the amount of the liquid stored in the storage means used; timing means for timing the dwell time of the liquid in the storage means; determination means for determining whether or not to replace the liquid stored in the storage means with the liquid supplied from the source; and the management system for managing the quality of a liquid stored in a storage means The management method comprises a processing means for performing processing on the liquid that is stored, and the management method includes: a first step in which the determination means determines whether or not to replace the liquid stored in the storage means with the liquid supplied from the supply source, based on the amount of liquid used identified by the identification means and the residence time measured by the timing means; and a second step in which the processing means performs a replacement process at least once, based on the determination result of the first step, in which the disposal means discards the liquid stored in the storage means, and then the supply means supplies the liquid to the storage means and stores it. 【0015】 The management system described in claim 1 includes a determination means for determining whether or not to replace the liquid stored in the storage means with liquid supplied from a supplier, based on the amount of liquid used identified by a specific means and the residence time measured by a timing means, and a processing means for performing the replacement process at least once based on the determination result of the determination means. Therefore, compared to the conventional technology (a technology that performs the replacement process based only on the residence time), it is possible to suppress the wasteful disposal of the liquid stored in the storage means and to improve the efficiency of the replacement process. 【0016】According to the management system described in claim 2, the determination means determines whether the amount of liquid used, as determined by the identification means, has reached a predetermined amount after the dwell time measured by the timing means has elapsed for a predetermined time. The processing means then executes a replacement process if the determination means determines that the amount has not reached a predetermined amount and therefore it is determined that replacement should be performed. This allows the replacement process to be executed at an appropriate timing, further improving the efficiency of the replacement process. 【0017】 According to the management system described in claim 3, if the determination means determines that a predetermined amount has been reached and therefore does not require replacement, the processing means resets the timing of the residence time by the timing means and starts timing again without performing the replacement process. This prevents the liquid stored in the storage means from being wasted and further improves the efficiency of the replacement process. 【0018】 According to the management system described in claim 4, the processing means adjusts the number of times the replacement process is performed based on the dwell time measured by the timing means and / or the amount of liquid used specified by the identification means. This allows the number of times the replacement process is performed to be adjusted based on the dwell time and / or the amount of liquid used, and enables the replacement process to be performed effectively. 【0019】 According to the management system described in claim 5, the processing means adjusts the number of times the substitution process is performed based on the measurement results of the temperature measuring means, so that the substitution process can be adjusted based on the ambient temperature around the storage means or the temperature of the liquid stored in the storage means, and the substitution process can be performed effectively. 【0020】 According to the management system described in claim 6, the determination means determines whether the number of times the substitution process has been executed has reached a predetermined number of times within a predetermined period, and the processing means determines that substitution should be performed because the determination means has determined that the predetermined number of times has been reached. Therefore, if the number of times the substitution process has been executed has reached a predetermined number of times, the substitution process can be performed additionally, making it easier to manage the quality of the liquid stored in the storage means. 【0021】According to the management system described in claim 7, the determination means determines whether or not to replace the liquid stored in the storage means with the liquid supplied from the supplier, based on the detection result of the quality detection means, the amount of liquid used identified by the identification means, and the residence time measured by the timing means. This allows the replacement process to be performed at a more appropriate timing and further improves the efficiency of the replacement process. 【0022】 According to the management system described in claim 8, the quality detection means includes a measuring means for measuring the amount of light emitted from a liquid dispensed into a reaction vessel placed at a predetermined position, and a quality identification means for identifying the quality of the liquid based on the amount of light emitted from the liquid measured by the measuring means. Therefore, the quality of the liquid can be detected relatively accurately, and the detection accuracy can be improved. 【0023】 The management method described in claim 9 includes a first step in which a determination means determines whether or not to replace the liquid stored in the storage means with liquid supplied from a supplier, based on the amount of liquid used identified by the identification means and the residence time measured by the timing means, and a second step in which a processing means performs a replacement process at least once based on the determination result of the first step. Therefore, compared to the conventional technology (a technology that performs a replacement process based only on residence time), it is possible to suppress the wasteful disposal of liquid stored in the storage means and to improve the efficiency of the replacement process. 【0024】 This is a plan view showing an overview of an analytical apparatus according to an embodiment of the present invention.

This first disposal channel 125a is constructed using, for example, known piping, and as shown in Figure 2, is provided between the first storage unit 111 and the first disposal destination, and is connected to the first storage unit 111 and the first disposal destination, respectively, by fasteners, etc. 【0088】 (Configuration - Management System - First Disposal Unit - First Disposal Valve) The first disposal valve 125b is for switching whether or not to send the liquid W1 in the first disposal passage 125a to the first disposal destination. This first disposal valve 125b is configured using, for example, a known electric valve or solenoid valve, and as shown in Figure 2, it is installed in the first disposal passage 125a and connected to the first disposal passage 125a by a fixing device or the like. 【0089】 (Configuration - Management System - First Disposal Unit - First Disposal Pump) The first waste pump is for sending the liquid W1 in the first waste passage 125a from the first storage unit 111 to the first disposal destination. This first waste pump is configured using, for example, a known pump, and is installed in the first waste passage 125a and connected to the first waste passage 125a by a fixing device or the like. 【0090】 (Configuration - Management System - Second Disposal Unit) The second disposal unit 126 is for disposing of the cleaning dilution solution W3 stored in the third storage unit 113 to a second disposal destination (not shown), and as shown in Figure 2, it is equipped with a second disposal passage 126a, a second disposal valve 126b, and a second disposal pump (not shown). 【0091】Here, "second disposal destination" refers to the means by which the cleaning dilution solution W3 is disposed of, such as a known waste tank. 【0092】 (Configuration - Management System - Second Disposal Unit - Second Disposal Channel) The second disposal channel 126a is a flow path for sending the cleaning dilution solution W3 from the third storage unit 113 to the second disposal destination. This second disposal channel 126a is constructed using, for example, known piping, and as shown in Figure 2, is provided between the third storage unit 113 and the second disposal destination, and is connected to the third storage unit 113 and the second disposal destination respectively by fasteners, etc. 【0093】 (Configuration - Management System - Second Disposal Unit - Second Disposal Valve) The second disposal valve 126b is for switching whether or not to send the cleaning dilution solution W3 in the second disposal passage 126a to the second disposal destination. This second disposal valve 126b is configured using, for example, a known electric valve or solenoid valve, and as shown in Figure 2, it is installed in the second disposal passage 126a and connected to the second disposal passage 126a by a fixing device or the like. 【0094】 (Configuration - Management System - Second Disposal Unit - Second Disposal Pump) The second waste pump is for sending the cleaning dilution solution W3 in the second waste passage 126a from the third storage unit 113 to the second disposal destination. This second waste pump is configured using, for example, a known pump, and is installed in the second waste passage 126a and connected to the second waste passage 126a by a fixing device or the like. 【0095】 (Configuration - First Control Unit) The first control unit 130 is a first control means that controls each part of the analyzer 1. Specifically, the first control unit 130 is a computer configured with a CPU, various programs interpreted and executed on the CPU (including basic control programs such as the OS, and application programs that are launched on the OS and realize specific functions), and internal memory such as RAM for storing various data (the same applies to the control unit body of the second control unit 140, which will be described later). 【0096】 Furthermore, the first control unit 130, in terms of functional concept, includes a specification unit 131, a determination unit 132, and a processing unit 133, as shown in Figure 3. 【0097】 The identification unit 131 is an identification means for identifying the amount of liquid W1 stored in the first storage unit 111 that is being used. 【0098】 Here, "amount of liquid W1 used" in this embodiment refers to the amount of liquid W1 stored in the first storage unit 111 that is relayed to the third storage unit 113 via the first relay unit 122 (more specifically, the amount used to replenish the washing diluent W3). 【0099】 The determination unit 132 is a determination means for determining whether or not to replace the liquid W1 stored in the first storage unit 111 with liquid W1 supplied from the supplier, based on the amount of liquid W1 used identified by the identification unit 131 and the residence time measured by the timing unit described later. 【0100】 The processing unit 133 is a processing means for performing a replacement process at least once based on the determination result of the determination unit 132. 【0101】 Here, "replacement process" refers to the process in which the liquid W1 stored in the first storage unit 111 is discarded by the first waste unit 125, and then the liquid W1 is supplied to the first storage unit 111 by the supply unit 121 for storage. 【0102】 Although the specific unit 131, the determination unit 132, and the processing unit 133 are components of the "management system" within the scope of the claim, for the sake of explanation, they will be described as being provided in the first control unit 130. 【0103】 Further details of the processing performed by this first control unit 130 will be described later. 【0104】 (Configuration - Second Control Unit) Returning to Figure 1, the second control unit 140 is a second control means that communicates with the first control unit 130 and controls the first control unit 130. As shown in Figure 1, the second control unit 140 is electrically connected to the first control unit 130 via wiring 2 and includes an operation unit, a communication unit, an output unit, a timing unit, a control unit body, and a storage unit (all of which are not shown). 【0105】Of these, the operation unit is an operating means that receives operation input to the second control unit 140. 【0106】 The communication unit is a communication means for communicating with the first control unit 130 and an external device (not shown) (for example, a host device for a Laboratory Information System (LIS)). 【0107】 The output unit is an output means that outputs various types of information based on the control of the second control unit 140, and is configured using, for example, known display means, printing means, or audio output means. 【0108】 The timing unit is a timing means for timing the dwell time, and is configured, for example, using a known timing device. 【0109】 Here, "residence time" refers to the time during which the liquid W1 remains in the first storage section 111. 【0110】 Although the timing unit is a component of the "management system" within the scope of the claim, for the sake of explanation, it will be described as being located in the second control unit 140. 【0111】 The control unit body is the main body of the second control unit 140. 【0112】 The storage unit stores programs and various data necessary for the operation of the first control unit 130 and the second control unit 140, and is configured using a known rewritable recording medium. For example, a rewritable non-volatile recording medium such as flash memory can be used. 【0113】 Furthermore, the memory unit includes an execution count table 141 as shown in Figure 4. 【0114】 The execution count table 141 is an execution count information storage means that stores execution count information. 【0115】 Here, "execution count information" refers to information indicating the number of times the replacement process is performed. 【0116】Furthermore, as shown in Figure 4, the execution count table 141 stores the items "liquid usage information," "dwell time information," and "execution count information" in an interrelated manner with the information corresponding to each item. 【0117】 Of these, the information corresponding to the item "Liquid Usage Information" is liquid usage information indicating the amount of liquid W1 stored in the first storage unit 111 that has been used. For example, as shown in Figure 4, this includes the amount of liquid W1 used, such as "5L or more and less than 10L". 【0118】 Furthermore, the information corresponding to the item "Dwelling Time Information" is dwelling time information indicating the duration of stay, and for example, as shown in Figure 4, this includes "less than 24 hours," which is a duration of stay. 【0119】 Furthermore, the information corresponding to the item "Execution Count Information" is the execution count information, and for example, as shown in Figure 4, it corresponds to the execution count "0 times," etc. 【0120】 With the analytical device 1 described above, the sample in the reaction vessel C3 can be automatically analyzed in the reaction line 81. 【0121】 Furthermore, since the analyzer 1 is equipped with a management system 120, compared to the conventional technology described above (a technology that performs the replacement process based solely on residence time), it is possible to suppress the wasteful disposal of the liquid W1 stored in the first storage section 111 and to improve the efficiency of the replacement process. 【0122】 (Control Processing) Next, the control processing performed in the analytical apparatus 1 configured as described above will be explained. 【0123】 The control process is the process for controlling the analyzer 1, and is broadly divided into the first control process and the second control process. The first and second control processes will be explained below. In the following explanation, the steps in the processes shown in Figures 5 and 6 will be abbreviated as "S". 【0124】 Furthermore, although the timing of executing the control processing (specifically, the first management processing and the second management processing) is arbitrary, in this embodiment, it will be described as being started after the power of the analyzer 1 is turned on. 【0125】 Furthermore, while the prerequisites for the control process are arbitrary, in this embodiment they are as follows. 【0126】 In other words, when the control process is activated, the amount of liquid W1 stored in the first storage unit 111 is full, the amount of cleaning concentrate W2 stored in the second storage unit 112 is full, and the amount of cleaning diluent W3 stored in the third storage unit 113 is zero. 【0127】 Furthermore, when the control process is activated, the supply valve 121b, the first relay valve 122b, the discharge valve 124b, the first waste valve 125b, and the second waste valve 126b are in the closed state, and the first relay pump 122c, the second relay pump 123b, the discharge pump, the first waste pump, and the second waste pump are not operating. 【0128】 Furthermore, regarding the method of replenishing the cleaning concentrate W2 in the second storage section 112, when the time to replenish the cleaning concentrate W2 arrives (for example, after a predetermined period of time has elapsed), the operator replenishes it by injecting the cleaning concentrate W2 contained in the replenishment tank through the opening (not shown) of the second storage section 112. 【0129】 (Control Processing - First Management Processing) First, the first management processing will be explained. 【0130】 The first management process is a process for managing the first storage unit 111, the second storage unit 112, and the third storage unit 113. 【0131】 When the first management process is activated, as shown in Figure 5, the first control unit 130 in SA1 determines whether or not the timing for replenishing the liquid W1 to the first storage unit 111 (hereinafter referred to as the "first replenishment timing") has arrived. 【0132】 The method for determining whether or not this first replenishment timing has arrived is arbitrary, but in this embodiment, the determination is made based on whether or not the water level of the liquid W1 stored in the first storage unit 111 is detected to be below a threshold by a detection sensor (not shown; for example, a float sensor, etc.; hereinafter referred to as the "first detection sensor") provided in the first storage unit 111. 【0133】 If the water level of the liquid W1 is detected to be below the threshold, it is determined that the first replenishment timing has arrived. If the water level of the liquid W1 is not detected to be below the threshold, it is determined that the first replenishment timing has not arrived. 【0134】 Then, the first control unit 130 transitions to SA2 if it determines that the first replenishment timing has arrived (SA1, Yes), and transitions to SA3 if it determines that the first replenishment timing has not arrived (SA1, No). 【0135】 In SA2, the first control unit 130 performs a process to replenish the liquid W1 in the first storage unit 111 (hereinafter referred to as the "first replenishment process"), and then proceeds to SA1. 【0136】 The processing details of this first supplementation process are arbitrary, but in this embodiment, the following processing is performed. 【0137】 Specifically, first, the first control unit 130 switches the open / closed state of the supply valve 121b to the open state, thereby sending the liquid W1 from the supply source to the first storage unit 111 via the supply passage 121a. 【0138】 Then, when the first detection sensor detects that the water level of the liquid W1 stored in the first storage unit 111 has reached the maximum water level (the water level when the first storage unit 111 is full), the first control unit 130 switches the open / closed state of the supply valve 121b to the closed state, thereby stopping the supply of liquid W1 from the source. 【0139】 In SA3, the first control unit 130 determines whether the timing for replenishing the washing diluent W3 to the third storage unit 113 (hereinafter referred to as the "second replenishment timing") has arrived. 【0140】The method for determining whether or not this second replenishment timing has arrived is arbitrary, but for example, it may be determined based on whether or not the water level of the cleaning diluent W3 stored in the third storage unit 113 is detected to be below a threshold by a detection sensor (not shown; for example, a float sensor, etc.; hereinafter referred to as the "second detection sensor") provided in the third storage unit 113, or whether or not replenishment instruction information instructing to replenish the cleaning diluent W3 in the third storage unit 113 has been received via the operation unit of the second control unit 140. 【0141】 If the amount of liquid W1 is detected to be below the threshold, or if the input of the replenishment instruction information is received, it is determined that the second replenishment timing has arrived. If the amount of liquid W1 is not detected to be below the threshold, or if the input of the replenishment instruction information is not received, it is determined that the second replenishment timing has not arrived. 【0142】 Then, the first control unit 130 transitions to SA4 if it determines that the second replenishment timing has arrived (SA3, Yes), and transitions to SA5 if it determines that the second replenishment timing has not arrived (SA3, No). 【0143】 In SA4, the first control unit 130 performs a process to replenish the third storage unit 113 with the cleaning diluent W3 (hereinafter referred to as the "second replenishment process"), and then proceeds to SA1. 【0144】 The processing details of this second supplementary process are arbitrary, but in this embodiment, the following processing is performed. 【0145】 Specifically, first, the first control unit 130 switches the open / closed state of the first relay valve 122b to the open state and drives the first relay pump 122c and the second relay pump 123b, respectively, thereby sending liquid W1 from the first storage unit 111 to the third storage unit 113 via the first relay path 122a, and sending cleaning concentrate W2 from the second storage unit 112 to the third storage unit 113 via the second relay path 123a. The liquid W1 and cleaning concentrate W2 sent in this way mix in the third storage unit 113 to generate cleaning dilution solution W3, which is then replenished in the third storage unit 113. 【0146】Then, when the second detection sensor detects that the water level of the cleaning diluent W3 stored in the third storage unit 113 has reached its maximum level, the first control unit 130 switches the open / closed state of the first relay valve 122b to the closed state and stops the operation of the first relay pump 122c and the second relay pump 123b, respectively, thereby stopping the discharge of liquid W1 from the first storage unit 111 and stopping the discharge of cleaning concentrate W2 from the second storage unit 112. 【0147】 In SA5, the first control unit 130 determines whether or not the timing for sending the cleaning dilution solution W3 to the cleaning unit 83 (hereinafter referred to as the "sending timing") has arrived. 【0148】 The method for determining whether or not this dispatch timing has arrived is arbitrary, but for example, it may be determined based on whether or not dispatch instruction information instructing the dispatch of the cleaning diluent W3 to the cleaning unit 83 has been received via the operation unit of the second control unit 140, or whether or not dispatch instruction information has been received from an external device. 【0149】 If the above transmission instruction information is accepted or received, it is determined that the transmission timing has arrived. If the above transmission instruction information is not accepted or received, it is determined that the transmission timing has not arrived. 【0150】 Then, the first control unit 130 proceeds to SA6 if it determines that the transmission timing has arrived (SA5, Yes), and proceeds to SA7 if it determines that the transmission timing has not arrived (SA5, No). 【0151】 In SA6, the first control unit 130 performs a process of sending the cleaning dilution solution W3 to the cleaning unit 83 (hereinafter referred to as the "sending process"), and then proceeds to SA1. 【0152】 The processing details for this transmission process are arbitrary, but in this embodiment, the following processing is performed. 【0153】Specifically, first, the first control unit 130 switches the open / closed state of the discharge valve 124b to the open state and drives the discharge pump, thereby discharging the cleaning dilution solution W3 from the third storage unit 113 to the cleaning unit 83 via the discharge passage 124a. 【0154】 Then, after a predetermined time has elapsed since the discharge of the cleaning dilution solution W3, the first control unit 130 switches the open / closed state of the discharge valve 124b to the closed state and stops the drive of the discharge pump, thereby stopping the discharge of the cleaning dilution solution W3 from the third storage unit 113. 【0155】 In SA7, the first control unit 130 determines whether or not the timing for discarding the cleaning dilution solution W3 from the third storage unit 113 (hereinafter referred to as the "discarding timing") has arrived. 【0156】 The method for determining whether or not this disposal timing has arrived is arbitrary, but for example, it may be determined based on whether or not disposal instruction information is input via the operation unit of the second control unit 140 instructing that the cleaning dilution solution W3 be disposed of from the third storage unit 113, or whether or not disposal instruction information has been received from an external device. 【0157】 If the above disposal instruction information is accepted or received, it is determined that the disposal timing has arrived. If the above disposal instruction information is not accepted or received, it is determined that the disposal timing has not arrived. 【0158】 Then, the first control unit 130 proceeds to SA8 if it determines that the disposal timing has arrived (SA7, Yes), and proceeds to SA9 if it determines that the disposal timing has not arrived (SA7, No). 【0159】 In SA8, the first control unit 130 performs a process to discard the cleaning dilution solution W3 from the third storage unit 113 (hereinafter referred to as the "disposal process"), and then proceeds to SA1. 【0160】 The details of this waste disposal process are optional, but in this embodiment, the following processes are performed. 【0161】Specifically, first, the first control unit 130 switches the open / closed state of the second waste valve 126b to the open state and drives the second waste pump, thereby sending the cleaning dilution solution W3 from the third storage unit 113 to the second waste destination via the second waste passage 126a. 【0162】 Then, when the second detection sensor detects that the water level of the cleaning diluent W3 stored in the third storage unit 113 has reached the minimum level (the water level when the amount stored in the first storage unit 111 is zero) (or when a predetermined time has elapsed since the cleaning diluent W3 was discharged), the first control unit 130 switches the open / closed state of the second waste valve 126b to the closed state and stops the driving of the second waste pump, thereby stopping the discharge of the cleaning diluent W3 from the third storage unit 113. 【0163】 In SA9, the first control unit 130 determines whether or not the timing for ending the first management process (hereinafter referred to as the "first termination timing") has arrived. 【0164】 The method for determining whether or not this first termination timing has arrived is arbitrary, but for example, it may be determined based on whether or not input of first termination instruction information to terminate the first management process has been received via the operation unit of the second control unit 140, or whether or not first termination instruction information has been received from an external device. 【0165】 If the input of the first termination instruction information is accepted or the first termination instruction information is received, it is determined that the first termination timing has arrived. If the input of the first termination instruction information is not accepted or the first termination instruction information is not received, it is determined that the first termination timing has not arrived. 【0166】 Then, if the first control unit 130 determines that the first termination timing has arrived (SA9, Yes), it terminates the first management process. On the other hand, if it determines that the first termination timing has not arrived (SA9, No), it proceeds to SA1 and repeats the process from SA1 to SA9 in the same manner thereafter. 【0167】This first management process enables the automatic replenishment of liquid W1 to the first storage unit 111, the replenishment of cleaning diluent W3 to the third storage unit 113, the delivery of cleaning diluent W3 to the cleaning unit 83, and the disposal of cleaning diluent W3 from the third storage unit 113, making it possible to easily manage the first storage unit 111, the second storage unit 112, and the third storage unit 113. 【0168】 (Control Processing - Second Management Processing) Next, we will explain the second management processing. 【0169】 The second management process is a process for managing the quality of the liquid W1 stored in the first storage unit 111, and is a process corresponding to the "management method" in the claims. 【0170】 In this embodiment, the second management process is executed in parallel with the first management process. 【0171】 When the second management process is activated, as shown in Figure 6, the first control unit 130 in SB1 starts timing the dwell time using the timing unit. 【0172】 The method for setting the start timing of this timing is arbitrary, but for example, a specific time (such as midnight) may be set, or the time immediately after the start of the analysis device 1 (second management process) may be set. 【0173】 Furthermore, while the method for measuring this dwell time is optional, in this embodiment, the dwell time is continuously measured regardless of whether the power supply of the analyzer 1 is ON or OFF while the second management process is being executed. 【0174】 However, this is not limited to the above. For example, if the power supply of the analyzer 1 is ON, the dwell time may be measured continuously, and if the power supply of the analyzer 1 is OFF, the dwell time measurement may be interrupted. 【0175】 In SB2, the first control unit 130 determines whether a predetermined time (for example, 48 hours) has elapsed, as measured by the timing unit. 【0176】Here, "the residence time has exceeded the predetermined time" in this embodiment refers to the situation where the residence time has exceeded the predetermined time while the power supply of the analyzer 1 is ON (including the case where the power supply of the analyzer 1 is turned OFF midway through), and also includes the situation where the residence time has exceeded the predetermined time when the power supply of the analyzer 1 is turned OFF midway through, and then the power supply of the analyzer 1 is turned ON afterward. 【0177】 Furthermore, the method for setting the above predetermined time is arbitrary, but for example, it may be set based on information indicating a reference time (hereinafter referred to as "reference time information") that is received as input via the operation unit of the second control unit 140 before the processing of SB2 (for example, before the start of the second management processing). Alternatively, it may be set based on reference time information received from an external device. Alternatively, it may be set based on a default value that is pre-stored in the storage unit of the second control unit 140. 【0178】 The first control unit 130 then waits until it is determined that the predetermined time has elapsed (SB2, No), and if it is determined that the predetermined time has elapsed (SB2, Yes), it proceeds to SB3. 【0179】 In SB3, the identification unit 131 identifies the amount of liquid W1 stored in the first storage unit 111 that is being used. 【0180】 The method for determining the amount of liquid W1 to be used is arbitrary, but for example, it may be determined as follows. 【0181】 In other words, the identification unit 131 may acquire analysis count information indicating the number of analyses performed by the analyzer 1 via the operation unit or receiving unit of the second control unit 140, acquire liquid usage amount information indicating the amount of liquid W1 required for one analysis in the analyzer 1 via the operation unit or receiving unit of the second control unit 140, and then identify the analysis count information by multiplying the amount of liquid usage information obtained by the second control unit 140 by the amount of liquid usage information obtained. 【0182】Alternatively, the identification unit 131 may acquire processing count information indicating the number of times a startup process or shutdown process is executed by the analyzer 1 via the operation unit or receiver unit of the second control unit 140, acquire liquid usage amount information indicating the amount of liquid W1 used in the replacement of liquid W1 in the piping performed during the startup process or shutdown process via the operation unit or receiver unit of the second control unit 140, and identify the device by multiplying the number of processing counts acquired by the liquid usage amount acquired by the liquid usage amount information. 【0183】 Alternatively, the identification unit 131 may acquire measurement count information via the operation unit or receiving unit of the second control unit 140, which indicates the number of times the concentration of the target substance in the sample was measured when the sample was reacted with the reagent in the analyzer 1, acquire liquid usage amount information via the operation unit or receiving unit of the second control unit 140, which indicates the amount of liquid W1 used in the above measurement, and identify the sample by multiplying the number of measurements acquired in the measurement count information by the amount of liquid usage acquired in the liquid usage amount information. 【0184】 Alternatively, the identification unit 131 may be identified based on the detection result of a first detection sensor provided in the first storage unit 111 (the water level of the liquid W1 stored in the first storage unit 111). More specifically, the identification unit 131 may be identified by calculating the difference between the detection result of the first detection sensor during the processing of SB1 (or the highest water level in the first storage unit 111) and the detection result of the first detection sensor during the processing of SB3, and multiplying the calculated difference by the cross-sectional area of ​​the first storage unit 111. 【0185】 In SB4, the determination unit 132 determines whether or not to replace the liquid W1 stored in the first storage unit 111 with the liquid W1 supplied from the supplier, based on the amount of liquid W1 used identified in SB3 and the residence time measured by the timing unit. 【0186】 The method for determining whether or not to perform this substitution is arbitrary, but in this embodiment, the determination is made based on whether or not the amount of liquid W1 used, as identified in SB3, has reached a predetermined amount (for example, 5 L) after a predetermined residence time has elapsed in SB2. 【0187】If the above-mentioned predetermined amount is reached, it is determined that no substitution will be performed; if the above-mentioned predetermined amount is not reached, it is determined that substitution will be performed. 【0188】 Then, if the determination unit 132 determines that a substitution is to be performed (SB4, Yes), it proceeds to SB5. On the other hand, if it determines that a substitution is not to be performed (SB4, No), it proceeds to SB7 without performing the substitution process. 【0189】 The method for setting the above predetermined amount is arbitrary, but for example, it may be set based on information indicating the standard usage amount of liquid W1 (hereinafter referred to as "standard usage amount information") that is received via the operation unit of the second control unit 140 before the processing of SB4 (for example, before the start of the second management processing). Alternatively, it may be set based on standard usage amount information received from an external device. Alternatively, it may be set based on a default value that is pre-stored in the storage unit of the second control unit 140. 【0190】 Furthermore, the processing of SB4 described above will be explained as the processing corresponding to the "first step" in the claims. 【0191】 In SB5, the processing unit 133 adjusts the number of times the replacement process is executed based on the residence time measured by the timing unit and the amount of liquid W1 used identified in SB3. 【0192】 The method for adjusting the number of executions is arbitrary, but in this embodiment, from the execution count information stored in the execution count table 141, execution count information corresponding to the dwell time measured by the timing unit at the time of processing SB5 (or when it is determined in SB2 that the predetermined time has elapsed) and the amount of liquid W1 used as specified in SB3 is extracted, and the number of executions of the extracted execution count information is adjusted as the number of executions to be adjusted. 【0193】 For example, if the residence time measured by the timing unit during processing SB5 is 48 hours (specifically, the time immediately after a predetermined period has elapsed while the power of the analyzer 1 is ON), and the amount of liquid W1 used as specified in SB3 is 5L, then the number of executions may be adjusted to 1. 【0194】Furthermore, for example, if the residence time measured by the timing unit during processing SB5 is 80 hours (specifically, the time immediately after the predetermined time of SB2 has elapsed when the power supply of the analyzer 1 was turned OFF midway through, and the amount of liquid W1 used as specified in SB3 is 5 L), the number of executions may be adjusted to 3. 【0195】 This SB5 process allows for adjusting the number of substitution operations based on the residence time and the amount of liquid W1 used, thereby enabling effective substitution. 【0196】 In SB6, the processing unit 133 performs the replacement process based on the number of executions adjusted in SB5. 【0197】 The details of this substitution process are arbitrary, but in this embodiment, it is performed as follows. 【0198】 Specifically, first, the processing unit 133 switches the open / closed state of the first waste valve 125b to the open state and drives the first waste pump, thereby sending the liquid W1 from the first storage unit 111 to the first waste destination via the first waste passage 125a. 【0199】 Next, the processing unit 133, when the first detection sensor detects that the water level of the liquid W1 stored in the first storage unit 111 has reached the minimum level (or when a predetermined time has elapsed since the liquid W1 was discharged), switches the open / closed state of the first waste valve 125b to the closed state and stops the operation of the first waste pump, thereby stopping the discharge of liquid W1 from the first storage unit 111. 【0200】 Next, the processing unit 133 switches the open / closed state of the supply valve 121b to the open state, thereby sending the liquid W1 from the supply source to the first storage unit 111 via the supply passage 121a. 【0201】 Next, if the first detection sensor detects that the water level of the liquid W1 stored in the first storage unit 111 has reached its maximum level, the first control unit 130 switches the open / closed state of the supply valve 121b to the closed state, thereby stopping the supply of liquid W1 from the source. 【0202】The first control unit 130 then executes the above-described series of processes a number of times adjusted by SB5. 【0203】 By performing SB4 and SB6 in this manner, the substitution process can be executed at the appropriate timing, thereby improving the efficiency of the substitution process. 【0204】 Furthermore, the processing of SB6 described above will be explained as the processing corresponding to the "second step" in the claims. 【0205】 In SB7, the processing unit 133 resets the dwell time measurement by the timing unit (i.e., returns the dwell time to zero). 【0206】 Specifically, if it is determined in SB4 that a replacement should be performed, the processing unit 133 executes the replacement process in SB6 and then resets the dwell time measurement by the timing unit. Then, as will be described later, if the first control unit 130 determines in SB8 (described later) that the second termination timing (described later) has not yet arrived, it re-measures the dwell time in SB1 and then executes the processes from SB2 to SB8 again. 【0207】 This makes it possible to properly execute multiple substitution operations. 【0208】 Furthermore, if it is determined in SB4 that no replacement is necessary, the processing unit 133 resets the dwell time measurement by the timing unit without performing the replacement process. Then, as will be described later, if the first control unit 130 determines in SB8 (described later) that the second termination timing (described later) has not yet arrived, it re-measures the dwell time in SB1 and then executes the processes from SB2 to SB8 again. 【0209】 This prevents the liquid W1 stored in the first storage unit 111 from being wasted, and makes it possible to improve the efficiency of the replacement process. 【0210】 In SB8, the first control unit 130 determines whether or not the timing for ending the second management process (hereinafter referred to as the "second termination timing") has arrived. 【0211】The method for determining whether or not this second termination timing has arrived is arbitrary, but for example, it may be determined based on whether or not input of second termination instruction information to terminate the second management process has been received via the operation unit of the second control unit 140, or whether or not second termination instruction information has been received from an external device. 【0212】 If the input of the second termination instruction information is accepted or the second termination instruction information is received, it is determined that the second termination timing has arrived. If the input of the second termination instruction information is not accepted or the second termination instruction information is not received, it is determined that the second termination timing has not arrived. 【0213】 Then, if the first control unit 130 determines that the second termination timing has arrived (SB8, Yes), it terminates the second management process. On the other hand, if it determines that the second termination timing has not arrived (SB8, No), it proceeds to SB1 and repeats the process from SB1 to SB8 in the same manner thereafter. 【0214】 This second management process makes it possible to suppress the wasteful disposal of the liquid W1 stored in the first storage unit 111, compared to the conventional technology described above (a technology that performs the replacement process based solely on residence time), and to improve the efficiency of the replacement process. 【0215】 (Effects of the Embodiment) As described above, according to the embodiment, a determination unit 132 determines whether or not to replace the liquid W1 stored in the first storage unit 111 with liquid W1 supplied from the supplier, based on the amount of liquid W1 used identified by the identification unit 131 and the residence time measured by the timing unit, and a processing unit 133 performs the replacement process at least once based on the determination result of the determination unit 132. Therefore, compared to the conventional technology (a technology that performs the replacement process based only on the residence time), it is possible to suppress the wasteful disposal of liquid W1 stored in the first storage unit 111 and to improve the efficiency of the replacement process. 【0216】Furthermore, the determination unit 132 determines whether the amount of liquid W1 used, as determined by the identification unit 131, has reached a predetermined amount after the dwell time measured by the timing unit has elapsed for a predetermined period of time. If the determination unit 132 determines that the amount has not reached a predetermined amount and the processing unit 133 determines that replacement is necessary, it executes the replacement process. This allows the replacement process to be executed at an appropriate timing, further improving the efficiency of the replacement process. 【0217】 Furthermore, if the processing unit 133 determines that the liquid W1 stored in the first storage unit 111 has reached a predetermined amount and therefore does not perform the replacement process, it resets the timing of the residence time by the timing unit and starts timing again. This prevents the liquid W1 stored in the first storage unit 111 from being wasted and further improves the efficiency of the replacement process. 【0218】 Furthermore, the processing unit 133 adjusts the number of times the replacement process is executed based on the residence time measured by the timing unit and / or the amount of liquid W1 used identified by the identification unit 131. Therefore, the number of times the replacement process is executed can be adjusted based on the residence time and the amount of liquid W1 used, and the replacement process can be executed effectively. 【0219】 Furthermore, the management method includes a first step in which the determination unit 132 determines whether or not to replace the liquid W1 stored in the first storage unit 111 with liquid W1 supplied from the supplier, based on the amount of liquid W1 used identified by the identification unit 131 and the residence time measured by the timing unit, and a second step in which the processing unit 133 performs the replacement process at least once based on the determination result of the first step. Therefore, compared to the conventional technology (a technology that performs the replacement process based only on the residence time), it is possible to suppress the wasteful disposal of liquid W1 stored in the first storage unit 111 and to improve the efficiency of the replacement process. 【0220】 [III] Modifications of the Embodiments The embodiments of the present invention have been described above, but the specific configurations and means of the present invention can be arbitrarily modified and improved within the scope of the technical idea of ​​each invention described in the claims. Such modifications will be described below. 【0221】(Regarding the problems to be solved and the effects of the invention) First, the problems to be solved and the effects of the invention are not limited to those described above. The present invention may solve problems not described above, produce effects not described above, solve only some of the problems described, or produce only some of the effects described. 【0222】 (Regarding distribution and integration) Furthermore, the electrical components described above are functional concepts and do not necessarily need to be physically configured as shown in the diagram. In other words, the specific forms of distribution and integration of each part are not limited to those shown in the diagram, and all or part of them can be functionally or physically distributed or integrated in any unit according to various loads and usage conditions. 【0223】 (Regarding shape, numerical values, structure, and time series) With regard to the components illustrated in the embodiments and drawings, the shape, numerical values, or the interrelationship of the structure or time series of multiple components can be arbitrarily modified and improved within the scope of the technical concept of the present invention. 【0224】 (Regarding the liquid) In the above embodiment, the liquid managed by the management system 1 was described as ion-exchanged water stored in the first storage unit 111, but it is not limited to this, and may be, for example, the washing diluent W3 stored in the third storage unit 113. 【0225】 In this case, in the second management process, the processes SB1 to SB8 may be performed on the washing dilution solution W3 stored in the third storage unit 113. 【0226】 (Regarding the analytical device) In the above embodiment, the analytical device 1 was described as being equipped with a chip removal external 92, but it is not limited to this, and for example, the chip removal external 92 may be omitted. 【0227】 (Regarding the reaction vessel) In the above embodiment, it was explained that the reaction vessel 80 has one reaction line 81, but this is not limited to this, and for example, there may be two or more. In this case, it is desirable that the reagent dispensing unit 60 and the sample dispensing unit 70 be configured to dispense into multiple reaction lines 81. 【0228】 Furthermore, although the above embodiment described the reaction line 81 as a transport-type reaction line, it is not limited to this, and for example, it may be a fixed-type reaction line. 【0229】 (Regarding the state detection unit) In the above embodiment, the state detection unit 103 was described as an imaging means, but it is not limited to this, and may be a pressure sensor or a light sensor (for example, an infrared sensor). 【0230】 (Regarding the management system) In the above embodiment, it was explained that the management system 120 is applied to the analyzer 1, but it is not limited to this, and may be applied to, for example, a reagent preparation device or a sample measuring device. 【0231】 Furthermore, although the above embodiment described the management system 120 as comprising a supply unit 121, a first relay unit 122, a second relay unit 123, a delivery unit 124, a first waste unit 125, and a second waste unit 126, it is not limited to this configuration. 【0232】 For example, when the liquid W1 stored in the first storage unit 111 is used in the washing unit 83, the management system 120 may omit the first relay unit 122, the second relay unit 123, and the second waste unit 126, and the discharge path 124a of the discharge unit 124 may be provided between the first storage unit 111 and the washing unit 83. 【0233】 In this case, steps SA3, SA4, SA7, and SA8 of the first management process may be omitted. 【0234】 Furthermore, for example, the management system 120 may further include a temperature measuring unit. This temperature measuring unit is a temperature measuring means for measuring the ambient temperature around the first storage unit 111 or the temperature of the liquid W1 stored in the first storage unit 111, and is configured, for example, using a known temperature sensor, and may be provided around or inside the first storage unit 111. 【0235】 In this case, for example, the execution count table 141 shown in Figure 7 may store the items "measured temperature information", "liquid usage information", "residence time information", and "execution count information" in relation to the information corresponding to each item. 【0236】 Of these, the information corresponding to the item "Measured Temperature Information" is the measured temperature information that indicates the temperature measured by the temperature measurement unit. For example, as shown in Figure 7, this includes the temperature measured by the temperature measurement unit, such as "less than 30 degrees". 【0237】 Furthermore, in SB5 of the second management process, the processing unit 133 may adjust the number of times the replacement process is executed based on the measurement results of the temperature measurement unit. 【0238】 In detail, the processing unit 133 extracts execution count information from the execution count table 141 in Figure 7 that corresponds to the temperature measured by the temperature measurement unit, the residence time measured by the timing unit during the processing of SB5, and the amount of liquid W1 used as identified by SB3, and adjusts the number of executions of the extracted execution count information as the number of executions to be adjusted. 【0239】 This process allows the number of replacement operations to be adjusted based on the measurement results from the temperature measurement unit, making it possible to perform the replacement process effectively. 【0240】 However, this is not limited to this. For example, in SB5, the processing unit 133 may adjust the number of times the replacement process is executed based solely on the measurement results of the temperature measurement unit. In this case, the execution count table 141 shown in Figure 7 may store the items "measured temperature information" and "execution count information" in relation to the information corresponding to each item. 【0241】 Furthermore, for example, the management system 120 may further include a quality detection unit. The quality detection unit is a quality detection means for detecting the quality of the liquid W1 stored in the first storage unit 111. 【0242】The specific configuration of this quality detection unit is arbitrary, but for example, from the viewpoint of accurately detecting the quality of liquid W1, the quality detection unit may be configured to include a photometric unit 101, which is a measuring means for measuring the amount of light emitted from liquid W1 dispensed into a reaction vessel C3 located at a predetermined position, and a quality identification means for identifying the quality of liquid W1 based on the amount of light emitted from liquid W1 measured by the photometric unit 101, and may be located near the reaction line 81. This makes it possible to identify the quality using the photometric unit 101 (measuring means) provided in the analyzer 1, thereby enabling accurate detection of the quality of liquid W1 while suppressing costs. 【0243】 The term "liquid W1 dispensed into reaction vessel C3" refers, for example, to a process in which liquid W1 is supplied from the first storage unit 111 to the washing tank (not shown) of the reagent dispensing unit 60, the reagent dispensing unit 60 aspirates the liquid W1 and dispenses it into reaction vessel C3, and then the substrate (substrate solution) is dispensed into the reaction vessel C3 by the substrate dispensing unit 84, or / or a process in which a washing diluent W3 containing liquid W1 is dispensed from the washing unit 83 into reaction vessel C3, and then the substrate is dispensed into reaction vessel C3 by the substrate dispensing unit 84. 【0244】 Alternatively, the quality detection unit may be configured using, for example, a known quality detection sensor (for instance, a quality detection sensor capable of detecting the quality of liquid W1 based on the amount of light emitted by liquid W1), and may be provided in the first relay valve 122b or the discharge valve 124b. 【0245】 In these cases, for example, in SB4 of the second management process, the determination unit 132 may determine whether or not to replace the liquid W1 stored in the first storage unit 111 with liquid W1 supplied from the supplier, based on the detection result of the quality detection unit (specifically, the result of whether or not the quality of liquid W1 meets a specific standard (for example, that the amount of light emitted by liquid W1 is below a threshold)), the amount of liquid W1 used as determined in SB3, and the residence time measured by the timing unit. 【0246】In detail, first, the determination unit 132 determines whether the amount of liquid W1 used, as identified by SB3, has reached a predetermined amount after the residence time measured by the timing unit has elapsed for a predetermined period of time. Here, the determination unit 132 determines that no replacement will be performed if the predetermined amount has been reached, and if the predetermined amount has not been reached, it further determines whether the quality of liquid W1 detected by the quality detection unit meets a specific standard. Then, the determination unit 132 determines that no replacement will be performed if the quality of liquid W1 meets the specific standard, and determines that replacement will be performed if the quality of liquid W1 does not meet the specific standard. 【0247】 This process allows the displacement process to be adjusted based on the ambient temperature around the first storage section 111 or the temperature of the liquid W1 stored in the first storage section 111, thereby enabling the displacement process to be carried out effectively. 【0248】 (Regarding control processing) In the above embodiment, the control processing was described as including the first management processing. However, it is not limited to this, and for example, if the operator manually performs the tasks related to the first replenishment processing, the second replenishment processing, the dispatch processing, and the disposal processing, the first management processing may be omitted. 【0249】 (Regarding the first management process) In the above embodiment, it was explained that the first control unit 130 performs the first replenishment process, the second replenishment process, the dispatch process, and the disposal process, but it is not limited to this. For example, an operator may manually perform the tasks related to the first replenishment process, the second replenishment process, the dispatch process, or the disposal process. 【0250】 In this case, the processing corresponding to the manual work described above among the processes SA1 to SA8 may be omitted. 【0251】 (Regarding the second management process) In the above embodiment, it was explained that in SB5, the processing unit 133 adjusts the number of times the replacement process is executed based on the residence time measured by the timing unit and the amount of liquid W1 used specified in SB3. However, it is not limited to this, and for example, the number of times the replacement process is executed may be adjusted based on only one of either the residence time measured by the timing unit or the amount of liquid W1 used specified in SB3. 【0252】In this case, either the liquid usage information or the residence time information stored in the execution count table 141 may be omitted. 【0253】 Furthermore, although the above embodiment described that the processing unit 133 performs the replacement process based on the number of executions adjusted in SB5, it is not limited to this. 【0254】 For example, the processing unit 133 may perform the replacement process with the same number of executions regardless of the residence time measured by the timing unit and the amount of liquid W1 used specified in SB3. In this case, the execution count table 141 and the processing of SB5 may be omitted. 【0255】 Furthermore, for example, the determination unit 132 determines whether the number of times the replacement process has been executed within a predetermined period (for example, one week, one month, or one year) has reached a predetermined number (for example, 10 times). If the determination unit 132 determines that the predetermined number has been reached and the processing unit 133 decides to perform the replacement, the processing unit 133 may perform the replacement process multiple times (for example, three times). On the other hand, if the determination unit 132 determines that the predetermined number has not been reached and the processing unit 133 decides not to perform the replacement, the processing unit 133 does not need to perform the replacement process. 【0256】 In this case, the processing unit 133 may, immediately after (or immediately before) performing the replacement process multiple times, notify the output unit of the second control unit 140 of a warning indicating that the number of executions has reached a predetermined number. 【0257】 This process allows for additional substitution operations to be performed if the number of substitution operations has reached a predetermined number, making it easier to control the quality of the liquid W1 stored in the first storage unit 111. 【0258】(Note) The management system of Note 1 is a management system for managing the quality of a liquid stored in a storage means, comprising: a supply means for supplying the liquid from a supplier to the storage means; a disposal means for disposing of the liquid stored in the storage means to a disposal site; a specification means for identifying the amount of the liquid stored in the storage means used; a timing means for timing the time the liquid remains in the storage means; a determination means for determining whether or not to replace the liquid stored in the storage means with the liquid supplied from the supplier, based on the amount of the liquid used identified by the specification means and the time the timing means timing; and a processing means for performing a replacement process at least once, in which the liquid stored in the storage means is disposed of by the disposal means, and then the liquid is supplied to the storage means by the supply means and stored, based on the determination result of the determination means. 【0259】 The management system in Appendix 2, in the management system described in Appendix 1, determines whether the amount of liquid used, as determined by the identification means, has reached a predetermined amount after the dwell time measured by the timing means has elapsed for a predetermined time, and the processing means executes the replacement process if it is determined by the determination means that the amount has not reached the predetermined amount. 【0260】 In the management system described in Appendix 3, if the processing means determines that the predetermined amount has been reached by the determination means and therefore does not perform the replacement process, it resets the timing of the dwell time by the timing means and starts timing again without performing the replacement process. 【0261】 The management system in Appendix 4 is a management system described in any one of Appendix 1 to 3, wherein the processing means adjusts the number of times the replacement process is performed based on the residence time measured by the timing means and / or the amount of liquid used identified by the identification means. 【0262】The management system described in Appendix 5 is a management system described in any one of Appendix 1 to 3, and includes a temperature measuring means for measuring the ambient temperature around the storage means or the temperature of the liquid stored in the storage means, and the processing means adjusts the number of times the replacement process is executed based on the measurement result of the temperature measuring means. 【0263】 The management system in Appendix 6 is a management system described in any one of Appendix 1 to 3, wherein the determination means determines whether the number of times the replacement process has been executed within a predetermined period has reached a predetermined number of times, and the processing means executes the replacement process multiple times if it is determined by the determination means that the predetermined number of times has been reached. 【0264】 The management system described in Appendix 7 is a management system described in any one of Appendix 1 to 3, and includes a quality detection means for detecting the quality of the liquid stored in the storage means, and the determination means determines whether or not to replace the liquid stored in the storage means with the liquid supplied from the supply source based on the detection result of the quality detection means, the amount of liquid used identified by the identification means, and the residence time measured by the timing means. 【0265】 The management system described in Appendix 8, in the management system described in Appendix 7, comprises a measuring means for measuring the amount of light emitted from the liquid dispensed into a reaction vessel located at a predetermined position, and a quality identification means for identifying the quality of the liquid based on the amount of light emitted from the liquid measured by the measuring means. 【0266】The management method in Appendix 9 is a management method for managing the quality of liquid stored in a storage means using a management system, the management system comprising: a supply means for supplying the liquid from a supplier to the storage means; a disposal means for disposing of the liquid stored in the storage means to a disposal site; a specification means for specifying the amount of the liquid stored in the storage means used; a timing means for measuring the retention time of the liquid in the storage means; a determination means for determining whether or not to replace the liquid stored in the storage means with the liquid supplied from the supplier; and the storage means The management method comprises a processing means for performing processing on the liquid, and includes a first step in which the determination means determines whether or not to replace the liquid stored in the storage means with the liquid supplied from the supply source, based on the amount of liquid used identified by the identification means and the residence time measured by the timing means; and a second step in which the processing means performs a replacement process at least once, based on the determination result of the first step, in which the disposal means discards the liquid stored in the storage means, and then the supply means supplies the liquid to the storage means and stores it. 【0267】 (Effects of the Appendix) The management system described in Appendix 1 includes a determination means for determining whether or not to replace the liquid stored in the storage means with liquid supplied from the supplier, based on the amount of liquid used identified by the specific means and the residence time measured by the timing means, and a processing means for performing the replacement process at least once based on the determination result of the determination means. Therefore, compared to the conventional technology described above (a technology that performs the replacement process based only on the residence time), it is possible to suppress the wasteful disposal of liquid stored in the storage means and to improve the efficiency of the replacement process. 【0268】According to the management system described in Appendix 2, the determination means determines whether the amount of liquid used, as determined by the identification means, has reached a predetermined amount after the dwell time measured by the timing means has elapsed for a predetermined period of time. The processing means then executes the replacement process if the determination means determines that the amount has not reached a predetermined amount and therefore it is determined that replacement should be performed. This allows the replacement process to be executed at an appropriate timing, further improving the efficiency of the replacement process. 【0269】 According to the management system described in Appendix 3, if the determination means determines that a predetermined amount has been reached and therefore no replacement is necessary, the processing means does not perform the replacement process. Instead, it resets the timing of the residence time measured by the timing means and starts timing again. This prevents the liquid stored in the storage means from being wasted and further improves the efficiency of the replacement process. 【0270】 According to the management system described in Appendix 4, the processing means adjusts the number of times the replacement process is performed based on the dwell time measured by the timing means and / or the amount of liquid used specified by the identification means. Therefore, the number of times the replacement process is performed can be adjusted based on the dwell time and / or the amount of liquid used, and the replacement process can be performed effectively. 【0271】 According to the management system described in Appendix 5, the processing means adjusts the number of times the substitution process is performed based on the measurement results of the temperature measuring means. This allows the substitution process to be adjusted based on the ambient temperature around the storage means or the temperature of the liquid stored in the storage means, and the substitution process can be performed effectively. 【0272】 According to the management system described in Appendix 6, the determination means determines whether the number of replacement operations has reached a predetermined number within a predetermined period, and the processing means determines that replacement should be performed because the determination means has determined that the predetermined number has been reached. Therefore, if the number of replacement operations has reached a predetermined number, the replacement operation can be performed additionally, making it easier to manage the quality of the liquid stored in the storage means. 【0273】According to the management system described in Appendix 7, the determination means determines whether or not to replace the liquid stored in the storage means with the liquid supplied from the supplier, based on the detection result of the quality detection means, the amount of liquid used identified by the identification means, and the residence time measured by the timing means. This allows the replacement process to be executed at a more appropriate timing, further improving the efficiency of the replacement process. 【0274】 According to the management system described in Appendix 8, the quality detection means includes a measuring means for measuring the amount of light emitted from a liquid dispensed into a reaction vessel placed at a predetermined location, and a quality identification means for identifying the quality of the liquid based on the amount of light emitted from the liquid measured by the measuring means. Therefore, the quality of the liquid can be detected relatively accurately, and the detection accuracy can be improved. 【0275】 According to the management method described in Appendix 9, the determination means includes a first step of determining whether or not to replace the liquid stored in the storage means with liquid supplied from the supplier, based on the amount of liquid used identified by the identification means and the residence time measured by the timing means, and a second step of the processing means performing a replacement process at least once based on the determination result of the first step. Therefore, compared to the conventional technology (a technology that performs a replacement process based only on residence time), it is possible to suppress the wasteful disposal of liquid stored in the storage means and to improve the efficiency of the replacement process. 【0276】1.
