[0006]

However, in the measuring device, a new measurement item may be added or the analysis determination method may be changed. Further, some users may want to change the judgment reference value and various conditions, or change the analysis processing procedure and processing speed.

Further, in the case where the control method from the measuring device must be changed in accordance with the change of the specifications of the sampler, or in order to remove a bug in the control program of the measuring device or the sampler or add a new function, The control program itself may need to be updated.

This is a problem that occurs because the combination of the versions of the control programs installed in the ROM of the measuring device and the sampler is different. For example, when it is sufficient to replace the ROM on the measuring device side, Since it is necessary to match the other specification with the specification change, R of the measuring device
When replacing the OM, the ROM on the sampler side may have to be replaced without fail.

Therefore, in the case of replacing the ROM as described above, it is necessary to manage the version of the control program of the currently delivered system and the types of the measuring device and the sampler for each analytical system shipped to the market.
Very difficult to maintain.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the drawings. The present invention is not limited to this. FIG. 2 shows a block diagram of the configuration of a sample analysis system which is an embodiment of the present invention. In the figure, 1
Reference numeral 01 denotes a measuring device, which is a device for performing various measurements and analyzes on a specimen sample such as blood.

Reference numeral 201 denotes a sampler, which is an apparatus in which a large amount of specimen samples are installed and which sequentially conveys the samples one by one to the measurement position of the measuring apparatus. Reference numeral 301 denotes a memory card, which has a control program for the measuring device and a control program for the sampler built therein, and includes data used in the analysis process as necessary. The memory card 301 is preferably composed of a non-rewritable non-volatile memory having a high reliability of data retention, for example, a ROM, but a memory having a RAM structure including a battery may be used.

Reference numeral 110 denotes a control unit of the measuring apparatus 101, which has a CPU 114, a RAM 112, a ROM 113, and an I / O.
The O controller 111, the address control circuit 115, the card detection unit 116, and the card mounting unit 117 are included.

Here, the card mounting portion 117 is a portion for accommodating the memory card 301 and has a contact which makes electrical contact with the memory card 301. The control program is read and data is input through this contact.

The card detection unit 116 is used for the memory card 30.
When 1 is inserted in the card mounting portion 117, the mounting of the card is detected by, for example, an electrical conduction signal. The I / O controller 111 is an interface unit that inputs and outputs data.

The address control circuit 115 has a ROM 113.
And a circuit for switching the connection of the card mounting unit 117 to the CPU. When the memory card 301 is not mounted in the normal card mounting unit 117, the address line of the ROM 115 is enabled to enable access to the ROM 113, and access to the card mounting unit 117 is prohibited. In this case, the CPU 114 will execute the control program of the measuring device built in the ROM 113.

When the memory card 301 is loaded in the card loading section 117, the card loading section 117
To enable access to the memory card 301 and prohibit access to the ROM 113. In this case, the CPU 114 executes the control program of the measuring device built in the memory card 301. The switching of access to the memory card and the ROM can be realized by, for example, inputting an electric signal generated in the card detection unit 116 to the address control circuit 115.

The measuring device 101 is also provided with operation keys 12
1, printer 122, LC for displaying various data
D123, measuring unit 124, fluid unit 125, and mechanism unit 12
6 is provided. For example, in the blood cell measurement system, the mechanism unit 126 is a unit that cleans a tube that sucks blood that is a sample. The fluid part 125 is a part for performing pretreatment for measurement, and suctions, quantifies blood,
Processing such as dilution and addition of reagents is performed. Moreover, the measuring unit 1
Reference numeral 24 is a portion for measuring and classifying the number, size, etc. of particles constituting blood by measuring an electric signal by an electric impedance method or the like. As described above, by providing the mechanism unit 126 and the fluid unit 125 on the measurement device side, the analysis process can be performed by the measurement device alone.

Reference numeral 210 is a control unit of the sampler 201, which includes a CPU 212, a RAM 213, a ROM 214 and an I.
It is composed of the / O controller 211. In addition, the sampler 201 also includes a fluid portion 221 and a mechanism portion 22.
It consists of two. The fluid section 221 of the sampler is a section for performing suction of blood as a sample, cleaning of the suction line, and the like. The mechanical unit 222 is a unit in which a rack on which a plurality of specimen samples are placed is installed and moved from the rack to a position where the samples are measured one by one.

The sampler having the above-mentioned structure conveys the installed samples to the measuring position of the measuring device 101 in order to stir the blood, suck the blood and wash the suction line.
C based on the control program stored in the RAM 213
The PU 215 controls these operations.

The control program of the sampler stored in the RAM 213 is the ROM 113 of the measuring device 101.
Alternatively, it is built in the memory card 301 and is transmitted from the measuring device 101 to the sampler 201 through the communication cable 401 after the power supply of the analysis system is turned on. The ROM 214 has a built-in minimum program (boot program) for starting the sampler and communicating with the measuring device after the power is turned on.

A communication cable 401 is a medium for connecting the measuring device 101 and the sampler 201 and transmitting control information and response information of the sampler. As the communication cable 401, for example, an RS232C cable is used. When various combinations of the measuring device 101 and the sampler 201 are conceivable according to the measurement purpose, scale, etc., such a communication cable is provided between these devices as separate and independent configurations as in this embodiment. 401
It is preferable to connect with.

The unit configuration in which the measuring apparatus 101 and the sampler 201 are separated and independent allows one sampler 201 to be used for another measuring system.
This is because it is possible to use a sampler that accommodates a small number of samples or a sampler that accommodates a large number of samples for one measurement system.
Therefore, when looking at various analysis systems as a whole,
Cost can be reduced by sharing the sampler as described above.

Further, the measuring device 101 and the sampler 201
By mounting a CPU on each of these and performing distributed processing, it is possible to simplify each control program, speed up processing, facilitate function expansion, and facilitate maintenance. However, in the case of a system in which the measuring device 101 and the sampler 201 are integrally configured, the printed circuit board of each device may be directly connected to the bus instead of the communication cable 401.

Next, in the sample analysis system of the present invention, an operation of updating the control program of the measuring device and the sampler will be described as an embodiment for updating the information of the measuring device and the sampler. Here, the update means an upgrade of the control program for the purpose of removing bugs of the control program and adding / changing the specifications. In addition, as additions / changes to specifications, display messages, measurement items and functions, analysis processing sequences, etc.
There are changes.

First, FIG. 3 shows a work procedure for mounting a memory card, which is carried out by a user when introducing a new control program for the measuring device and the sampler into the sample analysis system of the present invention. The memory card 3 is the control program of the measuring device and sampler to be upgraded.
01 is already built in.

In FIG. 3, the user first turns off the power source of the sample analysis system (step S11). Next, remove the cover of the memory card insertion slot (step S
12). The user confirms whether or not there is already a memory card in the insertion slot (step S13), and if there is, removes the inserted memory card by pressing the eject button (step S14) and proceeds to step S15. If there is no memory card, the process proceeds to step S15, and a new memory card is inserted into the insertion slot. Next, the cover is closed and the work is completed (step S16).

The above is the procedure for mounting the memory card by the user. After that, just by turning on the power of the user, the control program for the measuring device 101 built in the memory card is started, and the memory card is loaded. The control program for the sampler 201 which is built in is transferred to the sampler 201, and the sampler 201 is operated by the transferred new control program.

Next, the operation flow of the measuring device and the sampler will be described. FIG. 4 shows a main flow of the measuring apparatus 101. In step S21,
When the power of the measuring apparatus 101 is turned on, step S22
At, memory selection processing is performed.

The memory selection process is a part for deciding which one of the ROM and the memory card is installed as the control program of the operation to be performed, which is, as described above, determined by the card. The address control circuit receives the signal from the detection unit 116 and makes a hardware selection.

FIG. 5 shows the contents of this memory selection process. When the memory card 301 is inserted, electrical continuity occurs in the card detection unit 116. For example, 'L'
The level signal is sent to the address control circuit 115. In step S41, the address control circuit 115 determines the presence / absence of this'L 'level signal, and determines which one should be selected.

That is, when the'L 'level signal is input, the memory card is selected (step S42), and when the'L' level signal is not input, the ROM is selected. (Step S4
4).

Here, selecting the memory card 301 means, for example, in the address control circuit 115, validating the address line connected to the memory card 301 side and invalidating the address line connected to the ROM 113 side. Means

Similarly, selecting the ROM 113 enables the address line connected to the ROM 113 side in the address control circuit 115 to enable the memory card 30.
This means invalidating the address line connected to the 1 side. The above operation is not executed by the CPU by software, but is executed by hardware.

Here, the ROM 113 and the memory card 3
The control program stored in 01 is stored so as to start from the same address. After this, step S43
Alternatively, in step S45, the CPU executes the control program.

Next, step S23 of the main flow of FIG.
In, a self-check is performed, for example, a memory check, a checksum check of a set value used in analysis, or a check as to whether or not the operation of the mechanical section is normal. In step S24, it is waited whether a transfer request for the sampler control program is sent from the sampler 201 side. In step S25,
If there is a transfer request, the process proceeds to step S26, and the transfer routine of the sampler control program is activated.
It is preferable that the main body of the transfer routine is operated as a task different from the interrupt processing or the main flow.

If there is no transfer request even after waiting for a certain period of time, the process proceeds to step S27 and the fluid section 125 of the measuring device is automatically washed. In this embodiment, it is described that the fluid part is automatically cleaned after the transfer routine of the control program for the sampler is started. However, both the automatic cleaning of the fluid part and the transfer of the control program are concurrently performed as separate tasks. It is preferable to proceed.

Next, in step S28, it is checked whether or not the transfer of the control program is normally completed,
When the processing is normally completed, the automatic cleaning of the sampler fluid portion (step S30) and the analysis processing using the sampler (step S31) are executed. When the transfer of the control program is not normally completed, it is considered that there is no sampler, and the analysis process (step S29) is performed only by the measuring device. At this time, since an error has occurred on the sampler side, it is advisable to display a message on the LCD 123 to the effect that analysis will be performed manually.

Here, step S30 and step S31
The above process is executed in synchronization with the sampler 201 by appropriate data communication. The automatic cleaning in step S30 is a pretreatment for the analysis processing performed in step S31. In step S31, a series of processes of moving the specimen sample placed on the sampler, agitating the sample blood, aspirating, and analyzing the blood components in the measuring device are performed until the analysis of all the samples is completed.

Step S29 is a case where the transfer of the control program for the sampler is not successful, but it also includes the case where there is no sampler. By taking the procedure as shown in FIG. 5, one measuring device alone is used. Manual analysis can be performed for each sample.

Next, the processing on the sampler side will be described. FIG. 6 shows a main flow of processing on the sampler side. First, when the power is turned on (step S51), various data for self-check and sample supply are initialized at the same time as the measuring device (step S52). Next, in step S53, a program transfer request is sent to the measuring device through the communication cable, and the process proceeds to step S54.

In step S54, the process of receiving the control program for the sampler is performed. The received control program is stored in the area starting from a predetermined address position on the RAM 213. This receiving process will be described later.

In step S55, if the reception of the control program is completed normally, the process proceeds to step S56. If not, the process ends. That is, the sampler is in the same state as when it was separated from the measuring device, and the analysis process using the sampler is not executed.

In step S56, the received control program shifts control to the received control program in order to perform the processes of steps S57 and S58 below. The processes from step S51 to step S56 after the power is turned on are performed by the boot program installed in the ROM of the sampler. That is, in the boot program, the address of the instruction to be executed next is forcibly skipped to a predetermined start address on the RAM 213 where the received control program is stored. As a result, the processes of steps S57 and S58 described below are executed by the received control program.

In step S57, the fluid part 221 of the sampler is automatically cleaned to prepare for the next process. In step S58, a sample supply process is performed. That is, each processing of transporting the sample installed on the rack on the sampler to the measurement position, stirring the sample transported to the measurement position, and sucking blood to the sample is performed in this order.

The aspirated blood is collected in the fluid part 2 of the sampler.
From 21, it is conveyed to the fluid part of the measuring device through the connected tube, and is subjected to predetermined processing and analyzed. The above is the main flow of the sampler. As described above, the processes of steps S57 and S58 are performed in synchronization with the measurement device side by data communication.

Next, the receiving process on the sampler side will be described. FIG. 7 shows a flowchart of the reception process of the sampler. In step S61, the control program transferred from the measuring apparatus 101 is received. Here, the receiving operation and the above-mentioned transfer operation on the measuring device side may be performed by a procedure including error control such as a BASIC procedure or an HDLC procedure that is usually used. Also, the data transfer rate is
The normally used 19200 bps or 9600 bps may be used, but if a large number of transmission errors occur, transmission control may be performed so as to automatically reduce the transfer rate.

Next, in step S62, it is checked whether the received contents are correct. This is for example
This can be done by checking the checksum of all received data. If the received content is correct in step S63, the ACK data indicating the normal reception is returned to the measuring apparatus 101 (step S6).
4) If all data transfer is completed (step S)
71) and the reception process ends. If the received contents are not normal in step S63, NAK indicating a reception error is returned (step S65).

Next, the control program retransmitted from the measuring device is received (step S66). Step S6
In 7, S68 and S70, the received contents are checked in the same manner as in Steps S62, S63 and S64, and if normal, ACK is returned. If the received contents are not normal in step S68, NAK is returned (step S68).
69), the reception of the control program is abandoned, and the process ends.

Although the above flow shows the embodiment in which only the control program of the sampler program is transferred, it may be transferred if there are other necessary data and the like. Further, as the receiving process on the sampler side, the embodiment in which the control program is retransmitted is requested only once, but the present invention is not limited to this, and if the reception is not successful, the data transfer is repeated a predetermined maximum number of times. You may do it.

Next, the analysis processing flow on the measuring device side will be described. FIG. 8 shows the flowchart. In step S81, a standby state in which analysis processing can be started is entered, and a key input from the user is awaited. If a key input such as quality control, automatic cleaning, or printing is performed here, the menu process is executed (step S86). When the shutdown key is input, the shutdown process, that is, the cleaning of the fluid portion is performed (step S82).

After this, the power is further turned off by the user.
Based on the operation (step S83), if the power OFF operation is performed, the process ends. When a key input for starting the analysis process is made, the analysis process using the sampler or the analysis process using only the measuring device is started (step S84).

If the transfer to the control program to the sampler is normally performed, so-called automatic analysis processing using the sampler is executed, and if the transfer is not normal, the measuring device is used. It is ready for manual analysis. Next, in step S85, the analyzed result is output to the printer 122 or the like, and thereafter, the process returns to the standby state (step S81). The above is the analysis processing flow on the measuring device side.

In the sample analyzer shown in the above embodiment, the measuring device is
It operates by the control program in the built-in ROM 113, and when a memory card is inserted, it operates by the control program in the memory card.

Therefore, since the control program in the memory card does not operate after being read into the RAM 112 each time, there is no restriction on the memory capacity. That is, even if the size of the control program becomes large due to the addition of functions or the like, the control program can be operated without hardware changes such as board replacement.

Further, when a trouble occurs in this sample analysis system, a trouble check memory card is simply inserted into the measuring device to perform an operation (test operation) necessary for maintenance which is not included in a normal analysis process. Therefore, maintenance can be easily performed on site.

Only by doing so, the user can easily update the information such as the control program and data required for analysis.

It is possible to make changes, add functions, or change processing procedures.
