An equipment control controller 6 for controlling the operation of each equipment 7 is attached to each equipment 7, and each equipment control controller 6 stores a current state of an event occurring in each equipment 7 in a built-in memory. Is provided, and there is a master station controller 5 for communication that puts these equipment control controllers 6 and monitoring means 6a together.

The line management computer 1 manages the entire manufacturing line, reads the events occurring in each facility from the built-in memory of the monitoring means 6a, and creates a message to be notified to the operator. The message transmitter main body 2 transmits the message created by the line management computer 1, and the radio wave transmitter 3 radio wave transmits the message transmitted by the message transmitter main body 2. The message receiver 4 has a structure that can be carried by an operator,
As shown in FIG. 2, there are a liquid crystal display unit 12 and a speaker 13. Reference numeral 14 is a power switch, 15 is a liquid crystal reset switch, and 16 is a voice reset switch.

The operation of this embodiment will be described with reference to FIGS.

First, the monitoring means 6a is instructed of an event to output data. In this embodiment, when trouble occurs,
Event numbers 1, 2, 3, and 4 are assigned to these events by instructing simultaneous operation / simultaneous stop, material shortage, and model switching timing.
Attach.

Next, as shown in FIG. 3, a reference data table corresponding to the above-mentioned event number is created and stored in the line management computer 1. In this table, event number 1 is
Since a trouble has occurred, the message No. 1 is composed of a trouble name, a processing method, and the like. Event number 2 is an instruction for simultaneous operation and simultaneous stop. 2 consists of instructions for simultaneous operation and simultaneous stop. Event No. 3 is message NO. Because the material is insufficient. 3 is composed of the insufficient material name, and the remaining amount of the material when the material shortage is notified can be arbitrarily set according to the working condition. Event number 4 is the model switching time, so message number. Reference numeral 4 denotes a model switching time, and the timing at which the model switching time is notified can be arbitrarily set according to the working conditions.

Next, a transmission destination setting table as shown in FIG. 4 is created and stored in the line management computer 1. Based on FIG. 4, the transmission type, the equipment number, and the transmission destination are set for each event number. The transmission type indicates whether the transmission destination is an individual, a group, or all, the equipment number indicates the equipment number that the transmission destination operator is in charge of, and the transmission destination indicates the person in charge of the equipment where the event has occurred.

The above-mentioned instructions, preparations, and settings determine the work efficiency of the production line to be managed, but since they can be improved in sequence based on work experience, the operator's burden is reduced, and the optimum conditions are set. It is possible to manage the production line.

FIG. 5 is a flow chart showing the operation of this embodiment.

In step # 1 of FIG. 5, while the production line is in operation, the line management computer 1 monitors each equipment control controller 6 via the communication master station controller 5 of FIG. The memory of the means 6a is sequentially accessed to read out the event occurrence status signal in each equipment 7, and step #
Make a few decisions.

In step # 2, it is judged whether or not the signal is on, and if not, step # 2
Returning to step 1, the memory of the next monitoring means 6a is accessed, and if it is on, the process proceeds to step # 3.

In step # 3, it is determined whether the same signal as the signal that has been turned on has been turned off when the previous reading was performed. If it is off, it means that the event indicated by the turned-on signal has newly occurred, and the process proceeds to step # 4 and thereafter in order to create a message and set the destination. In this case, the signal turned on is turned off when the operator finishes processing the instruction of the message and resets the equipment.

In step # 4, the event generation equipment number and the event number are determined from the read signal, and the process proceeds to step # 5.

In step # 5, the message corresponding to the event number is extracted from the control data of FIG. 3, and the process proceeds to step # 6.

In step # 6, the event occurrence equipment number determined in step # 4 is written in the extracted message, and the process proceeds to steps # 7 and 8.

In steps # 7 and 8, the occurrence event number columns of the destination setting table of FIG. 4 are sequentially read for each transmission type and destination, and the event occurrence equipment number is within the equipment number range of the table. The column is determined, the transmission type and the destination of the determined column are extracted, and these are set as the transmission type and the destination to be transmitted, and the process proceeds to steps # 9 and 10.

In steps # 9 and 10, the extracted transmission type and transmission destination to be transmitted are combined with the message corresponding to the previously extracted event number,
The message is sent to the message transmitter main body 2, and the message transmitter main body 2 transmits the message by radio wave to the transmission type and the destination via the radio wave transmitter 3. When the transmission is completed, the process returns to step # 1. In this case, in this embodiment,
Although a call code for each person in charge was provided in the message receiver 4 (reception means), selection was made for each transmission type and destination.
It can also be performed by individually setting the frequency.
