DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a clinical test system according to the present invention. A plurality of automatic analyzers 4 can be connected to the clinical examination system 2 in this embodiment, for example, RS232C, but only one is shown in FIG. The clinical examination system 2 includes a protocol control master file 6 for storing control information of a communication protocol, a text edit master file 8 for storing edit control information of reception data and transmission data, and an automatic analyzer according to a communication protocol designated in advance. 4, and a communication unit 1 as a communication unit that transmits and receives data to and from the communication unit 4.
The data editing unit 14 edits the measurement result information extracted by 0 and stores it in the inspection result information file 12 as the inspection result information.

The clinical test system 2 in this embodiment is
It is realized by a general computer having a communication function. Communication unit 1 which is one of the characteristic components of this embodiment
0 is normally operated by an application called a handler, and this application is loaded into the memory of the computer and executed by the CPU to execute the processing described later. The files 6, 8 and 12 are stored in an external storage device such as a disk device.

FIG. 2 is a diagram showing an example of setting contents of the protocol control master file 6 in the present embodiment, which is an example of setting based on the example of the protocol shown in FIG. The protocol control master file 6 sets “label number” for identifying each processing content in each protocol, “communication direction” represented by transmission or reception, “text content” representing content of data to be received, and delayable time. “Delay time”, “time out”, “retry” of the number of times to retry the receiving operation, and “next process label” data indicating the label number of the process to be performed next when the process ends normally. In addition, in case the data other than the normal end of the process or data other than the text contents to be received is received, the "content" of the data received at that time and the label number of the destination of the process when the data is received , And a plurality of fields of “jump destination label in case of error” (two in FIG. 2). In this embodiment, one record is one process.
Note that the protocol control master file 6 in this embodiment stores only the procedure of a single protocol, and the procedures of other protocols are treated as different protocol control master files. That is, there are as many protocol control master files as there are protocols, and the protocol to be used is specified by specifying the file name. Of course, the control information of a plurality of protocols may be stored in one protocol control master file, and the corresponding control information may be extracted from the control information.

A feature of this embodiment is that information relating to each protocol used for communication between automatic analyzers is preset in the protocol control master file 6 and the text editing master file 8 as parameters, and when data is received, That is, the measurement result information is extracted based on the parameter. The parameters are the control information of the protocol stored in the protocol control master file 6 and the edit control information stored in the text edit master file 8. Further, at the time of data transmission, the inspection request item control information is edited according to the edit control information stored in the text edit master file 8 and the automatic analyzer 4
Is to send to. That is, since various information according to the protocol used for transmission / reception with the automatic analyzer 4 is selected and used, each master file 6,
It is possible to deal with the automatic analyzer 4 that uses different protocols with only one application using 8.

FIG. 4 is a flow chart showing the procedure of the data receiving process performed by the handler in the communication section 10. Hereinafter, the processing of the communication method with the automatic analyzer 4 will be described first with reference to this figure.

First, the automatic analyzer 4 for transmitting and receiving data
The protocol control master file 6 used between and is specified. Since the automatic analyzer 4 to be used is known in advance, the protocol control master file 6 containing the control information of the protocol used by the automatic analyzer 4 can be easily selected. Therefore, if the file name or protocol name is passed to the handler as a parameter in advance, the protocol control master file 6 to be used
Can be specified in advance. The handler first accesses the record with the label number "0001" in the record group of the selected protocol control master file 6, and reads the communication direction and the text content (step 1
01). In this example, "ENQ" is first "received". That is, the communication system is led by the automatic analyzer 4. Therefore, the communication unit 10 is in a reception waiting state until it receives data.

When data is received (step 1)
02), and compares the content with the "text content" (step 103). The received data is the same as the text content "E
If it is NQ ", it is determined to be normal and the" next processing label "
Then, the process proceeds to the processing of the label number "0002" specified in (step 105). If there is a predetermined process to be performed, the process is performed in advance (step 104). If the received data is "EOT", it is determined that there is an error, and the process designated by the "label" of the "error jump destination label" is entered (step 106). In this example, the label number "00
01 ”, that is, the process returns to the beginning. If there is any other data that can be received, the data may be designated after the“ error jump destination label (2) ”as described above.

The data receiving process is carried out along the flow of this process. Continuing the description based on the example shown in FIG. 2, after "ENQ" is received, the "next process label" is displayed. The designated label number "0002" is processed. That is, the communication unit 10 receives “2” after receiving the data.
After "00 ms" has elapsed, "ACK" is "transmitted." This processing is based on the delay time, the text content, and the data specified in the communication direction. When the item control request from the automatic analyzer 4 is received, the inspection item requested to the automatic analyzer 4 is selected and transmitted as item control information (inspection request item control information). After receiving "ACK", in response, "ACK" is returned.
It is possible to make a plurality of inspection requests to the automatic analyzer 4 by repeating the processing from 3 "to" 0005 ". Details of this transmission processing will be described later. In the setting example shown in FIG. A timeout is set for processes with a communication direction other than "0001" and "reception", so each reception process retries 5 times if it does not receive within 3 seconds after transmission, and data is received during that time. It is necessary to receive it.The processing when a timeout occurs is set in the jump destination label at the time of error.

When the automatic analyzer 4 wants to send the measurement result information to the clinical test system 2, the label number "000".
In the process of "3", the data whose text content is "measurement result" is sent. When the communication unit 10 receives the "measurement result",
The processing is moved to the label number designated as the “error destination label (1)”, that is, “0006”, and the reception of the measurement result information is started. Then, the communication unit 10 uses the label number “0
By receiving the data whose text content is "EOT" in the process of "006", the process of the label number "0001", that is, the process of receiving the measurement result information is repeated until the initial state is restored.

In this way, the communication unit 10 sends and receives data based on the control information of the protocol stored in the protocol control master file 6, so the clinical examination system 2 requests the examination according to the specified protocol. It is possible to easily obtain the measurement result information of the contents. In the present embodiment, if one application that can selectively use the control information of the protocol is prepared, the control information of the protocol adapted to the automatic analysis device is included even if a new automatic analysis device is added. All that is required is to create the protocol control master file 6.

Next, a data extraction process performed when the communication unit 10 receives the measurement result information in the above process will be described. This process is a process performed by the handler in the communication unit 10, and the measurement result information is extracted from the received data by operating by referring to the text edit master file 8. The data editing unit 14 stores the inspection result information in the inspection result information file 12 by editing and processing the extracted measurement result information.

FIG. 5 is a diagram showing the contents of the text editing master file 8 in this embodiment. This is a data format received by the communication section 10 shown in FIGS. 6 (a) and 6 (b). It is an example of the setting content based on. Figure 5
Group No. “0001” in FIG. 6 has setting contents corresponding to FIG. 6A, and Group NO “0002” has setting contents corresponding to FIG. 6B. The group No. “0003” and thereafter will be described later.

FIG. 6A shows fixed length received data including a fixed number of fixed length measurement result information. FIG.6 (b) is
The variable-length reception data includes at least one piece of fixed-length measurement result information.

In FIG. 5, the text edit master file 8 has a "group NO", which is an identification number assigned to each data format to be transmitted and received, a "start position" indicating the start address of each data field, and its size (number of bytes). ) And the like, "size" indicating each item, "item NO" uniquely attached to each data, and "content" indicating the content of the data. Since the data format used for transmission / reception to / from the automatic analyzer 4 is known in advance, the content of the text edit master file 8 is preset based on this data format.
Further, the text edit master file 8 has special meanings other than the storage position and the size depending on the setting values of the "start position" and "size" columns, respectively, but the meaning will be described later.

FIG. 7 is a flow chart showing the procedure of the data extraction processing in this embodiment, and the data extraction processing in the communication section 10 will be described below with reference to this drawing.

First, the communication unit 10 always reads out the group No. "0000" of the text edit master file 8 first (step 201) and determines the type of received data (step 202). The determination is made by comparing the field value of the received data of the field of the size "2" from the start position "1" with the setting value of the item NO.

If the data shown in FIG. 6A is received, the value of 2 bytes from the beginning of the received data is "SI".
Is. On the other hand, according to the text edit master file 8, “SI” exists and it is the group number “000”.
Therefore, the received data can be determined to be the data corresponding to the group No. “0001” in the text edit master file 8.

Thus, when the type of data is known,
After that, the group number of the text edit master file 8
Each data is extracted from the received data based on the edit control information related to "0001" (step 20).
3). According to the edit control information, the storage position of the measurement result information and the like can be specified. That is, specifically, data of 5 bytes from the start position “3”, that is, “00001” in FIG. 6A is sequence data, data of 6 bytes from the start position “8”,
That is, “0001.1” in FIG.
Data of 6 bytes from the start position “14”, that is, “0002.2” in FIG. 6A.
Is result 2 data, 6 from start position “20”
Byte data, that is, “000” in FIG.
3.3 ″ is extracted as the data of the result 3. In this way, it is possible to obtain the measurement result information having a fixed length of 3 constants included in the received data.
Group No. “000” of text edit master file 8
The edit control information related to "1" includes a record in which the start position is blank and the size is "1", but this record causes the data received by the handler to have a fixed number of fixed lengths. It can be recognized that the data includes result information.

Next, if variable-length data including at least one fixed-length measurement result information shown in FIG. 6B is received for a fixed number of fixed-length data, the beginning of the received data The value of 2 bytes from is "A". On the other hand, according to the text edit master file 8, "A" exists and it is the item number of the group number "0002". Therefore, the received data can be determined to be the data corresponding to the group No. “0002” in the text edit master file 8.

Thus, when the type of data is known,
After that, the group number of the text edit master file 8
Each data is extracted from the received data based on the edit control information related to "0002". According to the edit control information, each measurement result information is extracted by obtaining the head storage position and data length of the measurement result information from the text edit master file 8. That is, the sequence data can be extracted as 4-byte data from the start position “3” as in the above, but the received data can be obtained by finding a record in which the subsequent start position is blank and the size is “2”. It is possible to recognize that the data is variable-length data including at least one piece of fixed-length measurement result information. Then, by finding a record in which the start position is “7” and the size is blank, the start storage position of the measurement result information is “7”,
It is possible to recognize that the data length of the measurement result information included in the received data is 5 bytes by obtaining the size "5" of the record in which the start position following this is blank.

Therefore, data of each "5" bytes from the start position "7" in FIG. 6B, specifically "004.4", "005.5", "006.6".
Can be extracted as measurement result information. The process of extracting measurement result information from the received data is the value obtained by subtracting the number of control characters, the size of sequence data, etc. from the received data length obtained in the data reception process as the total data length of the actually extracted measurement result information. Repeat until just before crossing. The maximum number of the measurement result information obtained repeatedly can be obtained from the value of the size in which the start position following the record including the data length of the measurement result information described above is blank. In the example shown in FIG. 5, it is “20”.

As described above, by effectively using the columns of "start position" and "size" in the text editing master file 8, it is possible to obtain edit control information having a meaning other than the storage position and size. The measurement result information contained in the data received by the specified protocol can be extracted. The setting position of each edit control information set in the text editing master file 8 may be the record position shown in FIG. 5 because it may be arranged with the handler using the text editing master file 8. No need.

Further, assuming that the received data is variable-length data including a plurality of variable-length measurement result information that is delimited by delimiters and connected, as shown in FIG. The "start position" in is replaced with the "start delimiter position" included in the received data, and the "size" is replaced with the "maximum length" between delimiters to set delimiter information, and this delimiter information may be used as edit control information. .

As described above, by setting parameters based on each protocol in the text editing master file 8 in advance, one general-purpose application can be created, and measurement can be performed from received data in various data formats. Result information can be extracted.

By the way, in the present embodiment, the transmission of the inspection request item control information is performed by presetting the format of the data to be transmitted to the text editing master file 8 in addition to the above-mentioned measurement result information receiving processing. It can also be used for processing. That is, in step 103 in FIG. 4, when the communication unit 10 receives the item control request from the automatic analyzer 4, the communication unit 10 selects the inspection item to request to the automatic analyzer 4 and sets it as item control information (inspection request item control information). The transmission processing of the inspection request item control information will be described here.

The item control request sent from the automatic analyzer 4 specifies the format of the transmission data, that is, the format of the control text, to which the inspection request item control information is to be transmitted. Therefore, if it is a transmission request of the inspection request item control information in the format of the control text 1, the group No. “000” in the text editing master file 8 shown in FIG.
The number of bytes of the CH (channel) to be set is obtained by referring to the number of control CHs and the number of control CH bytes of 3 ". As with this parameter, the start position is blank and the actual data is set in the size. The inspection request item control information is edited based on the parameters, the transmission data shown in FIG. 6C is created, and the transmission data is transmitted to the automatic analyzer 4.
Each record included in each control text is set by the agreement with the handler, as in the case of receiving.

As described above, according to the present embodiment, if one general-purpose application is prepared by using the protocol control master file 6 and the text editing master file 8 described above, various protocols can be used. It is possible to easily send and receive data to and from the corresponding automatic analyzer 4.

In the above embodiment, the edit control information used when receiving data from the automatic analyzer 4 and the edit control information used when transmitting data to the automatic analyzer 4 are stored in the same text edit master file 8. However, they may be provided separately for reception and transmission.

Further, although the present invention is applied to the field relating to a clinical examination system, it is not limited to this field and can be applied to other fields utilizing a system which needs to support a plurality of communication protocols. There is no end.

[0045]

According to the invention described in claim 1, since the information about each communication protocol used for the communication between the automatic analyzers is set in advance in the protocol control master file as the control information, it is actually used. When the automatic analyzer to be specified is specified, it becomes possible to select and use the control information of the protocol according to it when transmitting / receiving data. In other words, if one general-purpose application that can selectively use the control information of the communication protocol is prepared, the control information to be used is switched even when connecting to each automatic analyzer that uses a different communication protocol. Only by doing so, it is possible to respond quickly. Further, even when a new automatic analyzer is added, it is only necessary to add the control information, and it is not necessary to create a new application.

According to the second aspect of the present invention, since the edit control information corresponding to the format of the received data is set in the text editing master file for reception in advance, the format of the actually received data is determined. However, by selecting and using the edit control information corresponding to it, the measurement result information can be extracted quickly and easily.
In other words, if you prepare one general-purpose application that can selectively use the editing control information stored in the text editing master file for reception, even if you receive data of various data formats, the data format can be immediately received. By using the editing control information corresponding to the recognized data format, the measurement result information can be extracted. Further, even when a new data format is added, it is only necessary to add the edit control information and there is no need to create a new application.
In particular, according to the invention of claim 3, when fixed length data including a fixed number of fixed length measurement result information is received, according to the invention of claim 4, at least one fixed length measurement result. When variable-length data including information is received, according to the invention of claim 5, when variable-length data including a plurality of variable-length measurement result information separated by delimiters and connected is received. , Respectively, it is possible to correspond.

According to the sixth aspect of the invention, the editing control information corresponding to the format of the data for editing and transmitting the inspection request item control information is set in advance in the text editing master file for transmission. By selecting and using the editing control information corresponding to the actually requested data format, it becomes possible to quickly and easily create and transmit the transmission data including the inspection request item control information.
Therefore, even when a new data format is added, it is only necessary to add the edit control information, and it is not necessary to create a new application.
