Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a control system applied to, for example, managing a digital data recorder with a microcomputer.

[Summary of the invention]

In this invention, an address pointer memory for storing a pointer corresponding to an address of data stored in a data memory of a controlled device is provided in the controlled device, the content specified by the pointer is predetermined, and communication is started. Sometimes,
A pointer is sent to the control device, and the control device can read or change the contents of the data memory based on the pointer information.The control device can control different types of controlled devices, and the control device can control different types of controlled devices. software can be versatile.

[Conventional technology]

2. Description of the Related Art Data recorders are known that convert measured data into digital data and record this digital data on a magnetic tape using a rotating head.

As a more special type of digital data recorder, an electrocardiogram holter has been proposed, in which a patient carries an ultra-small recorder at all times to record the patient's electrocardiogram waveform over a long period of time.

In this type of data recorder, in addition to recorded data, additional data such as recording date and time is stored in the recorder's memory. When a microcomputer is used to manage such a data recorder and analyze recorded data, it becomes necessary for the microcomputer to read additional data.

[Problem to be solved by the invention]

In conventional data recorders, when the microcomputer knows the address where the additional data is stored, the additional data can be read without any problem. However, if the address where the additional data is stored in a different model is unknown, there is a problem in that the microcomputer cannot read the additional data. Therefore, it was necessary to prepare software for controlling the data recorder for each model.

Therefore, an object of the present invention is to provide a control system in which the software of a control device can have versatility for a controlled device such as a data recorder.

[Means to solve the problem]

This invention provides an address pointer memory (4) that stores pointers corresponding to addresses of data stored in a data memory (5) of a controlled device (1).
1), the content specified by the pointer is predetermined, and at the start of communication, the pointer is sent to the control device (2), and the content of the data memory (5) is determined based on the pointer information. This is a control system that allows the control device (2) to read or change the information.

[Effect]

Address x of address pointer memory 4 of controlled device 1
1 to X4 respectively store addresses of the data RAM 5 in which data of the promised contents are stored. At the start of communication, the control device 2 reads the contents of this address pointer memory 4, and then the control device 2 can read the required data from the data RAM 5 or change the data.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, 1 is a controlled device such as an electrocardiographic Holter, and 2 is a control device. In the case of an electrocardiographic Holter, the controlled device 1 includes electrodes for detecting electrocardiographic waveforms, a signal processing system that processes detection signals from electrodes to form recording signals;
A head/tape running mechanism and the like are provided for recording recording signals. A CPU 3 is provided for controlling the operation of the controlled device 1, and the CPU 3 is coupled to an address pointer memory 4 and a data RAM 5 via a bus. Further, 6 is the serial number I10.

A serial number 1108 provided in the control device 2 and a serial number 1106 of the controlled device 1 are connected via a cable 7. The controlled device 2 is composed of a microcomputer 9. In connection with the microcomputer 9, a floppy disk drive 10, a keyboard 11 and a
An RT display 12 is provided. The software of the microcomputer 9 is read and installed by the floppy disk drive 10.

The control device 2 is used to manage the controlled device 1 . In other words, the control device 2 reads additional data stored in the controlled device 1 and the microcomputer 9
Additional data may be stored in the memory of the CRT display 12 or displayed on the CRT display 12. Also, the microcomputer 9
It is possible to change additional data.

As shown in FIG. 1, when the controlled device 1 and the control device 2 are connected by the cable 7, for example, when the micro combiator 9 of the control device 2 is turned on, communication starts. Ru. First, the contents of the address pointer memory 4 of the controlled device 1 are sent to the control device 2 .

As shown in FIG. 2, the address pointer memory 4 has, for example, four addresses xi to x4, and data y1 to y4 are stored in each address. This data y1
to y4 are addresses of the data RAM 5. That is, as shown in FIG. 3, recording date and time data is stored at address y1 of the data RAM 5. data RA
The other addresses y2, y3 and y4 of M5 contain the patient's I
The D number, error rate, and ID number of the set are each stored.

As in this example, the address x1 of the address pointer memory 4 corresponds to the recording date and time data, and the addresses X2, X3
and x4 is the patient's ID number, the error rate, and the set I
It was agreed in advance that each number corresponds to the D number.
Both the controlled device 1 and the controlled device 2 are known.

After receiving the pointer information from the address pointer memory 4, the control device 20 microcomputer 9 reads or changes any additional data required. This process can be performed by the microcomputer 9 selectively specifying a desired address among the addresses yl to y4 of the data RAM 5. Further, under the control of the microcomputer 9, additional data read from the data RAM 5 of the controlled device 1 is displayed on the CRT display 12.

Even if the controlled device is a different model and the address of the additional data on the data RAM is different, the contents of the address pointer memory 4 are first transferred to the microcomputer 9 of the control device 2, as described above. By reading the data, additional data can be read, displayed, changed, etc. without any problems.

〔Effect of the invention〕

According to this invention, an address pointer memory indicating an address where additional data of the controlled device is stored is provided, and the controlled device reads this address pointer when communication between the controlled device and the controlled device is started. There is no need to change the software of the control equipment depending on the model of the equipment. Therefore, software for managing control devices such as data recorders and analyzing recorded data can have versatility.
