Abstract

PURPOSE:To prevent the mispacking of a package without increasing the scale of a device nor increasing the cost by deciding whether the packing combination of packages is allowed or not based on the information received from the packed package. CONSTITUTION:When a package 5 is packed into a port 11 or 12, an information processing part 2 reads the BLANK information received from the package 5 and each signal of the PKG type and sends them to a control part 3 after coding them. The BLANK information shows the presence or absence of the package packing, and the PKG type shows the type of the packed package. Then the part 3 sends an enable EN signal to the packed package 5 when the allowed packing combination is coincident with either one of those packing information. If no coincidence is obtained, the packed package 5 is not enabled and an alarm generating part is started for production of an alarm to show the mispacking. As a result, the mispacking is prevented without increasing the scale of a device nor increasing the cost.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a unit-type package mounting system, and in particular, to changing the combination of package mounting on a unit having a plurality of slots for package mounting within preset conditions. The present invention relates to a unit-type package mounting system that allows for

[Conventional technology]

In conventional unit-type package mounting systems of this type, software recognizes identification (ID) signals sent from each package to determine whether or not the package is mounted in the slot of the unit according to the mounting combination conditions. A method of determining this is adopted.

[Problem to be solved by the invention]

The above-mentioned software-based recognition method in the conventional package mounting system cannot determine whether the mounting state is correct or incorrect unless the software system is in an operating state, so a drawback is that it is often impossible to quickly confirm the presence or absence of incorrect mounting at the time of package mounting. There is. Furthermore, in devices that do not need to be equipped with a software system, installing software solely for the purpose of preventing incorrect implementation will result in the device becoming larger and larger.
There is a problem of high prices.

[Means to solve the problem]

The package mounting system of the present invention is a unit-type package mounting system in which a plurality of packages can be attached to and detached from the unit, and the package has blank information indicating that it has been mounted when attached to the unit and its own package type. The unit has a signal circuit that transmits package type information to be displayed and receives an enable signal given from the unit, and the unit receives the blank information and the package type information transmitted by the mounted package and displays the package type information. Logic that determines whether or not the combination of both information is a preset permissible combination, and if it is a permissible combination, gives an enable signal to the mounted package, and if it is not a permissible combination, issues an alarm signal indicating incorrect mounting. It has a gate circuit.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a flow diagram showing an embodiment of the present invention.

The unit 1 has ports 11 and 12 for signal connection for each slot for package mounting, and also has an information processing section 2, a control section 3, and an alarm issuing section 4. Package 5 that can be attached to and detached from the slot of unit 1 is blank (BLANK).
It has an information circuit 51, a package (PKG) type circuit 52, and an enable (EN) signal processing circuit 53.

In this embodiment, there are two types of packages 5 (PKGA
and PKGB), on the one hand, PKGA has a capacity of two ports, and on the other hand, PKGB has a capacity of one point. It is also assumed that this system can handle the capacity of two ports at the same time.

According to this package mounting combination condition, five mounting combinations shown in Table 1 are allowed.

When the package 5 is mounted on the first table port 11 or 12, the BLANK information and PKG type signals sent from the package 5 are manually input to the information processing section 2. The information processing section 2 and the control section 3 are composed of logic gate circuits,
The information processing unit 2 receives the BLΔN from the mounted package 5.
Each signal of K information and PKG type is read, coded, and sent to the control unit 3 as mounting information. The BLΔNK information indicates whether a package is mounted, and the PKG type indicates the type of package mounted. In this embodiment, each port requires only one bit, so encoding in the information processing unit 2 is omitted. Even if the data is sent to the control B3 in 4-bit parallel format, there will be no significant difference in the circuit scale, but if the number of ports and the types of pancakes increase, it is better to encode the data in the information processing unit 2 to prevent an increase in the circuit scale. When the mounting information given from the information processing 82 matches any of the mounting information of the five allowed mounting combinations as shown in Table 1, the If they do not match, the installed package 5 is not enabled and the alarm issuing section 4 is activated to issue an alarm indicating incorrect mounting.

For example, if you first install a PKGA package on port 1 and then a PKGB package on port 2, the package for port 2 (PKCB) will not match any of the implementation combinations in Table 1. It is determined to be incorrect implementation. Furthermore, if a PKCB package is mounted on port 1 and then a PKGA package is mounted on port 2, the conditions in Table 1 are not met, so the port 2 package (PKGA) is determined to be incorrectly mounted.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to instantly determine whether a mounting combination is permissible based on information from the mounted packages, and to prevent incorrect mounting before or during system startup. can be determined. Furthermore, even in systems that do not have software installed, it is possible to prevent incorrect mounting without increasing the size and price of the device.

Claims (1)

[Claims] In a unit-type package mounting system in which multiple packages can be attached to and detached from a unit, the package transmits blank information indicating that it has been mounted when attached to the unit and package type information indicating its own package type. The unit further includes a signal circuit for receiving an enable signal given from the unit, and the unit receives the blank information and the package type information transmitted by the mounted package, and the combination of the two pieces of information is set in advance. It has a logic gate circuit that determines whether or not the combination is an allowable combination, and if the combination is an allowable combination, gives an enable signal to the mounted package, and if the combination is not an allowable combination, issues an alarm signal indicating incorrect mounting.
