Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a distributed inspection system, and provides a new system that can easily accommodate changes or additions to measurement targets.

Various measurement systems have been proposed to automatically measure and process multiple measurement targets.

By the way, conventional systems of this type are generally designed according to the measurement target, and when adding or changing the measurement target, hardware or software must be changed or added. , which had the disadvantage of lacking flexibility.

The present invention solves these conventional drawbacks, and will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention, in which 10 is a module, 100 is a storage unit, and 200 is a setting device.

One module has a temperature measurement function using a thermocouple, a temperature measurement function using a resistance thermometer, an analog output signal sending function, an analog function signal sending function, a digital input signal processing function, a digital output signal sending function, a communication function, etc. something that has a function and is configured as a single-functional form or
It is constructed as a combined functional form. In FIG. 1, the detailed configuration of module 1° is omitted, and only the parts relevant to this description are shown. 11 internal bus interfaces, 1
2 is a ROM N+ in which the CPU 13 stores unique information necessary to set the operating conditions of the module.
4 is a RAM for temporarily storing operating conditions set based on information stored in the ROM 13; 15 is for transmitting and receiving signals between the module and an external device 4 (measurement target, control target, etc.); A useless input/output interface,
A bus 16 commonly connects these constituent blocks. A plurality of n modules 10 constructed in this manner are housed in a common storage unit 100 and connected via a bus.

The storage unit 100 has a communication function, a calculation function, etc. in addition to a management function for the stored modules.
FIG. 1 shows parts related to the present invention. 110
120 is an external bus interface, 120 is an internal bus interface, 130 is a CPU, 14oid: ROM in which unique information necessary for setting the operating conditions of the storage unit is stored, 150 is stored in ROM + 40 RAM 160, which is used to temporarily store operating conditions set based on information, is a bus that commonly connects each of these constituent blocks. Although a plurality of m storage units 100 configured in this manner may be connected via a bus, FIG. 1 shows an example of one unit.

The setting device 200 has a function of setting the operating conditions of the storage unit 1oo and the module 1o stored in the storage unit 100, and can arbitrarily create an operation program for the entire /stem. This setting device 20
0 is external bus interface 210, CPU 220
, a display section 240 such as a keyboard 230XCRT, an operating condition setting program storage section 25o1, and an internal bus 260 that commonly connects these constituent blocks. The setting device 200 configured in this manner is connected to the storage unit 10 via the external bus B to form a system.

The operation of the system configured in this way will now be explained.

First, a setting program stored in the program storage section 250 of the setting device 200 is driven, and further, a target for setting operating conditions is specified. As a result, the contents of the information stored in the condition setting ROM 13 or +40 of the designated setting target are read out and displayed on the display unit 240 in a format that is easy for the operator to understand.

In this way, the operator operates the keyboard 250 while looking at the measurement function, measurement range, number of measurement channels, and other operation information displayed on the display section 240 to set the necessary operating conditions, and the set conditions Set condition R
Temporarily stored in AM 14 or 150. After the necessary operating conditions are set in this way, a series of operations will be executed according to the set operating conditions.

According to such a system configuration, the difference in the functions of each module and storage unit can be indicated by the content of the information stored in the condition setting ROM, so that the operating condition setting program of the setting device can be fixed. Additionally, when adding a module or storage unit with new functions, it is only necessary to store the specified information in the condition setting ROM of the module or storage unit to be added, which is much simpler than conventional systems. can be achieved.

In the above embodiment, an example in which one storage unit is connected has been described, but it is also possible to connect a plurality of storage units.

Further, as shown in FIG. 2, a plurality of storage units 100 are connected to a relay device 300 via a bus,
00 may be connected to the setting device 200 via a bus.

According to such a configuration, the system can be configured using more modules. In this case, each relay device 300 is also provided with a block for setting operating conditions similar to the storage unit 1oo and the module.

Further, in the above embodiment, an example has been described in which the set operating conditions are distributed and temporarily stored in each setting target, but it is also possible to temporarily store the set operating conditions in a concentrated manner in the setting device.

As described above, according to the present invention, it is possible to realize a new distributed measurement system that can easily respond to changes or additions of measurement targets, and the practical effects are significant.
