Description

Error message system and how to send error messages {FAULT MESSAGE SYSTEM AND METHOD FOR TRANSMITTING FAULT MESSAGES}

The present invention relates to a plurality of manufacturing units distributed in a space and having means for generating and displaying an error message, a fault alarm box configured to receive and send an error message, and to receive an error message. The present invention relates to an error message system including at least one receiving device and a method for transmitting an error message.

As circuit devices for transmitting alarms and processing data, circuit devices are known in which data from a plant is transmitted by a controller to a separate alarm controller via a bus system and from that individual alarm controller to a network operator's network via a modem. . The data is then sent to the manager's mobile phone (German patent publication no. 196 54 859 C1). The provision of alarm controllers, including data memory, program memory and speech synthesizers, connected displays and keyboards in all plants is expensive, especially when a large number of plants are distributed in space. In addition, all data can only be sent to a network worker via a modem that is connected separately, and the network worker must send the data back to the destination.

An object of the present invention is an error message system that has a simple structure, can be easily installed, can be adapted to different manufacturing units, and can provide excellent error messages, especially when the manufacturing units are distributed and arranged in space. To provide. It is also an object of the present invention to provide a method of operating such an error message system.

According to the invention, the first object mentioned above is that a plurality of manufacturing units are arranged to form at least one group, each manufacturing unit being connected with a transmission unit for wireless transmission of an error signal, each group being a data receiving unit And a data receiving unit is connected to the error alarm box, and the error alarm box is connected to the processing computer.

Assigning a transmission unit to each manufacturing unit for sending an error signal to the data receiving unit allows the manufacturing unit to be simply integrated into the error message system. This advantage is especially noticeable when the error message system is subsequently extended by another manufacturing unit.

By combining the manufacturing units to form a group, the manufacturing units can be covered according to the technical aspect. Therefore, it is preferable to combine the production units of the individual production lines to form one group in each case. By assigning data receiving units to each group, errors can be assigned to individual groups very quickly.

According to a preferred aspect, the data receiving unit is provided with means for displaying an error signal, preferably a lamp. Since the manufacturing units are distributed and arranged in space, the display means of such a data receiving unit serves to grasp the current state, in particular, to quickly grasp the error location.

The connection of the error alarm box to the processing computer allows the error message to be sent for recording and evaluation, which is different from that sent by the error alarm box to the receiving device, e. It has nothing to do with it.

In view of the spatial separation between the processing computer and the manufacturing unit, it has been found desirable to connect the error alarm box to the processing computer via a network connection so that the processing computer location can be freely selected within the network. In particular, it has turned out that it is desirable to configure the network connection as a LAN connection.

According to another manufacturing control and manufacturing plan, it is desirable to connect the processing computer to another computer through another network.

In order to adapt the error message system to the respective field of application, it has proved desirable to process the error signal in an error alarm box. For this purpose, the error alarm box has a data editing unit. Accordingly, when an error message is transmitted by an error alarm box, it is possible to accurately define the error message.

The second object of the present invention is that the manufacturing unit forms at least one group, error signals of the manufacturing units of the group are transmitted to the data receiving unit, and the data receiving unit transmits the error signal of each group to the error alarm box and , Is achieved by sending an error message to the processing computer by the error alarm box.

The advantage of this method is that if an error signal of a group of manufacturing units is transmitted to one data receiving unit each, an error can be assigned to each group in a very simple manner.

According to one preferred embodiment, the visual representation of the error signal in the individual data receiving unit, preferably using a lamp, allows the error to be assigned to the individual group in an improved manner, or to visualize the group by the error. It can be improved. This makes it possible for the person in charge to find the error location quite simply, especially when a large number of manufacturing units are combined to form a large number of groups, for example a manufacturing line.

It is also desirable to edit the error signal prior to conversion to the error message. This allows you to specify exactly where an error message exists. The transfer of error messages from the error alarm box to the processing computer allows further recording, analysis and adjustment of only the actual error message without the need for further processing of the error message.

If the error message causes the manufacturing unit to take the necessary method of eliminating the error, during the course of this method, for example during the test, the error signal can be regenerated and transmitted to the error alarm box. In order to prevent such a signal from being detected as an error message, it is desirable that the error signal is converted into an error message only if the error signal is present in the error alarm box for a predetermined time. This prevents unnecessary error messages from being received and displayed in the receiving device of the manufacturing unit manager because the manufacturing unit manager is already working on eliminating the error. This error signal is not sent to the processing computer so that only error messages that reflect the actual error are detected.

By generating an augmentation signal in the presence of an error message and generating an error message only when the threshold is reached, the predetermined time in the error alarm box can be determined in a very simple manner. The predetermined time can be arbitrarily set according to the magnitude of the threshold and the amplification width of the signal.

During the elimination of errors in the manufacturing unit, a phenomenon often occurs in which an error signal is generated for a relatively short time and transmitted to an error alarm box, and the error signal is generated with the corresponding signal level and converted into an error message. According to another embodiment, the occurrence of such an error message can be prevented by detecting an error signal following the error message by the error alarm box when the previous error signal has been attenuated for a predetermined time.

It is also desirable to transmit the error message sent by the error alarm box to the receiving device of the processing computer and the person in charge after different time elapses. Thus, if an error message is sent from the error alarm box to the processing computer in just 5 seconds for accurate recording, then a transmission is made, for example, one minute later to the receiving device of the person in charge.

Hereinafter, the present invention will be described in detail with reference to Examples.

1 is a block diagram of an error message system according to the present invention.

2 is a diagram illustrating signal variation of a manufacturing unit and an error alarm box.

3 is a diagram illustrating a second signal variation of a manufacturing unit and an error alarm box.

The error message system shown in FIG. 1 is composed of a plurality of manufacturing units 1 forming a plurality of groups I-III as a manufacturing line. The manufacturing unit is provided with means 2 for displaying an error signal. Each of the manufacturing units 1 includes a transmission unit 3 for wirelessly transmitting an error signal to the data receiving unit 4 assigned to each group I-III. The data receiving unit 4 has a lamp 5 which visually displays the error signal. The error signal is then sent by the data receiving unit 4 to the error alarm box 6. As will be described below, if an error message is generated from an error signal of the data editing unit 6a of the error alarm box 6, the error message is sent to the person in charge of the manufacturing unit 1, in particular a technician who can take countermeasures. Is sent in SMS form to the mobile radiotelephone 7.

At the same time, the error message is transmitted to the processing computer 9 via the network 8 configured as a LAN so as to include initialization data and / or recording data, whereby the error message is stored in the database for evaluation. This database may be allocated to the processing computer 9 or to a separate data memory 10 which is connected to the processing computer 9 via another network 11. The network 11 comprises another computer 12 capable of recalling such data from the data memory 10 or the processing computer 9.

2, the error signal generated by the manufacturing unit is shown in the upper diagram. The intermediate diagram shows how the error signal sent from the manufacturing unit 1 is edited in the data editing unit 6a of the error alarm box 6, the lower diagram being generated by the error alarm box 6. Shows an error message. The upper diagram shows that an error occurs at time t1 and an error signal is generated by the manufacturing unit 1. The error signal transmitted to the error alarm box 6 is thus edited in the error alarm box as an error signal having an enhanced level. At time t2 the error signal reaches a threshold, which is then converted into an error message according to the diagram below.

An error signal is generated by an error generated in the manufacturing unit 1 at time points t3 and t5. Since the time to time t4 and time t6, respectively, is not sufficient to reach the limit, such an error signal cannot be converted into the corresponding error message. These short error signals are a common occurrence in test operations for maintenance or repair work and therefore do not represent a true error.

The diagram shown in FIG. 3 shows the signal variation according to the preceding event. The upper diagram shows the error signal generated by the manufacturing unit 1. The middle diagram shows the editing of the error signal sent from the manufacturing unit 1 in the error alarm box 6, and the lower diagram shows the generated error message.

The error generated in the manufacturing unit 1 at the time point t1 generates an error signal. The error signal transmitted to the error alarm box 6 is thus edited in the error alarm box as an error signal having an enhanced level. At time t2 the error signal reaches a threshold, which is then converted into an error message according to the diagram below. At time t3, the error signal is no longer present in the manufacturing unit 1. Therefore, the error signal of the error alarm box 6 is reduced from the limit value to 0 during a predetermined time up to t5. Error signals arriving during this time t4 are not detected in the error alarm box 6. This makes it possible to filter the error signal of the manufacturing unit 1, which is generated continuously for a short time and indicates that it is a test run, so that only genuine errors can be transmitted as error messages to the receiving device of the person in charge and the processing computer. Thus, looking at the intermediate diagram, only the error of the manufacturing unit 1 at time t6 will generate an error signal of the error alarm box 6.
