Description

[0001] The present invention relates to a control apparatus for spinning machine,

[0001] The present invention relates to a spinning machine control apparatus, and more particularly, to a spinning machine control apparatus using a TDMA protocol for collecting operational information and various information of a spinning machine using a TDMA protocol.

Since the beginning of development, spinning machines have been realized by electronic devices, hydraulic devices, air pressure, etc. in order to shorten the process, continuous operation, large capacity winding, and high speed. That is, the spinning machine is treated as a high-precision machine tool equipped with a high-level computer.

The spinning process using a spinning machine can be carried out by blowing & opening, carding, combing, drawing, roving, ring spinning, winding, The yarn is delivered through a baling & packing process, which is done through all automation systems. For example, all processes such as auto feeding, auto-doffing, automatic cotrol, and automatic transfortation are linked to automated facilities.

On the other hand, a plurality of spinning machines are usually grouped into a spinning process. In this case, the administrator or the user needs to separately control the spinning machines, check the operation status, and collect various information. In this case, if the number of the entire spinning machines is not large, the manager can access each spinning machine and collect the spinning machine status or information. However, this also has a problem that it is difficult to efficiently access the spinning machine and the work time . Especially, when the number of spinning machines is large, it takes much time to manage the spinning machines. In some cases, the management cost is increased because a plurality of managers are needed.

Accordingly, a method of managing a spinning machine using a communication protocol has been sought. For example, the wireless local area communication (WiFi) protocol can be used.

However, the WLAN protocol is ineffective because a large amount of data is required to be allocated for a large bandwidth, so that a collision occurs every spinning machine. It is also vulnerable to noise.

Korean Unexamined Utility Model Publication No. 2000-0000914 (Jan. 15, 2000, spinning control system) Korean Patent Registration No. 10-01463540000 (May, 1998, 11, Method and system for monitoring spinning machine motion)

It is therefore an object of the present invention to provide a spinning-machine control device which enables communication units provided for each spinning machine to effectively collect and manage the operation state and various information of the spinning machine through the TDMA communication system .

It is another object of the present invention to provide a spinneret control device that enables a message to be transmitted without collision when a message is transmitted between spinning machines.

According to an aspect of the present invention for achieving the above object, there is provided an image forming apparatus comprising: a master spinner; At least one slave spinner for receiving a control command or transmitting operation information during a predetermined network cycle with the master spinner; And a communication unit that is provided in the master spinner and the slave spinner, so that transmission and reception of the control command and the operation information are performed through the TDMA communication method.

Here, the network cycle includes 32 slots (slot 0 to slot 31), the slot includes 32 frames (Frame 0 to Frame 31), and the frame is further divided into 32 subframes SF0 to SF31).

The subframe includes a lock time, a preamble, a control, a payload, and an end of file (EOF).

Each of the subframes is 512 bits, the lock time is 200 bits, the preamble is 100 bits, the control is 50 bits, The payload consists of 110 bits and the end of file (EOF) consists of 52 bits.

In addition, the time required for the network cycle is 0.5 seconds (sec).

On the other hand, in the present invention, when one of the individual spinning machines is set, the master spinning machine establishes a communication path with the portable terminal device via the network.

According to the spinning machine control apparatus of the present invention, the following effects are obtained.

Since the plurality of spinning machines transmit and receive the information on the control command and the operation state by using the TDMA communication method, the present invention has a strong effect on the message collision and noise generated in the general wireless local area communication method.

In a state where one master spinning machine and a plurality of slave spinning machines are set, the master spinning machine can control only a desired slave spinning machine.

In addition, the administrator can monitor the operating state of the slave textile machine in real time. Therefore, an effect of effectively performing the spinning process can be expected.

Hereinafter, embodiments of a spinning machine control apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an example in which a plurality of spinning machines are grouped into one group in order to explain a spinning machine control apparatus of the present invention. FIG.

As shown, a plurality of spinning machines 100, 110, 120, and 130 form a group. Here, the group means that all of the spinning machines 100, 110, 120 included in the group 130 are connected to the communication network. Therefore, there is no space limitation. For example, if they are physically and spatially separated and are located at different positions, they should be regarded as being included in one group if they are connected to a communication network. In addition, if it is bound to a communication network via a repeater, it is possible to form a plurality of spinning machines located in a much wider area as a single group.

Communication units 102, 112, 122, and 132 are installed in each of the spinning units (i.e., 'individual spinning units') 100, 110 and 120 forming the group. The communication units 102, 112, 122 and 132 use the TDMA communication scheme and these communication units 102, 112, 122 and 132 are connected to the spinnaker 100 (110, 120) (Not shown), or may be installed in connection with an existing control panel (not shown).

As will be described below, the display unit 114 is configured in the master spinner 100. Although it is assumed that the display unit 114 is configured only for the master spinning machine 100 for the purpose of description of the present embodiment, the display unit is also configured in all the spinning machines 110 and 120 (130) other than the spinning machine.

The network cycle using the TDMA communication scheme is shown in FIG.

Referring to FIG. 2, the TDMA communication protocol has a network cycle repeated at regular intervals, and the time required for the network cycle is approximately 0.5 seconds. Of course, the required time can be changed.

The network cycle consists of a total of 32 slots (slot 0 to slot 31). Each slot is composed of 32 frames (Frame 0 to Frame 31), and each frame is composed of 32 subframes (SF0 to SF31).

Here, the first frame among the frames constituting each slot is a start frame transmitted by the master, and indicates the start time of the network cycle. And the frame from the second frame to the 31st frame is a frame used by each slave to transmit and receive data.

3 is a block diagram of a TDMA control command protocol according to the present invention.

The TDMA control command protocol is stored in a subframe and includes a lock time, a preamble, a control, a payload, and an end of file (EOF) as shown in the figure. Each of these protocols has 200 bits, 100 bits, 50 bits, 110 bits, and 52 bits. The total is 512 bits (bits).

Here, the control protocol can perform a 1: N broadcast function with a plurality of slaves, and include slave ID information and commands to transmit commands to specific slaves. The payload also includes spinning machine information.

A series of processes of controlling the individual spinning machines and collecting information using the spinning machine control device constructed as above will be described with reference to FIGS. 4 and 5. FIG.

1, in which a plurality of spinning machines are grouped into one group, reference numeral 100 is referred to as master spinning machine in each individual spinning machine, and remaining 110, 120, and 130 are slave spinning machines do. Of course, this is only one example, so it is natural that another spinner can be a master spinner.

FIG. 4 is a flowchart illustrating a process in which a master spinning device controls a slave spinning device according to the present invention.

First, one of the plurality of individual spinning machines is set as master spinning machine 100 (SlOO).

The master spinning machine 100 sets the remaining spinning machines 110, 120 and 130 as slave spinning machines. At this time, the master spinning device 100 assigns a slot number to each slave spinning device to be set (s110). Accordingly, each of the slave spinning machines 110, 120, and 130 has a unique ID.

The first command for the spinning process is applied while the master spinning machine 100 and the slave spinning machines 110, 120, and 130 are set.

Then, the master spinner 100 transmits a start command to the slave spinters 110, 120 and 130 through the first frame (Frame 0) of the slot 0 to synchronize with the slave spinters 110, 120 and 130 (S120).

When the synchronization is completed, the network cycle shown in FIG. 2 repeats at a predetermined cycle, that is, a cycle of 0.5 seconds, and the data is transmitted (s130). That is, the master spinning machine 100 transmits the necessary data to the slave spinning machines 110, 120, and 130 in the 31st frame in the second frame of the slot 0 together. As an example of the data, it may be a control command for controlling the slave spinning machines 110, 120 and 130.

This process is also applied to the other slave spinning machines 110, 120, and 130. That is, data is transmitted for each of the slave spinning machines 110, 120, and 130 using the first frame and the frames thereafter.

On the other hand, the master spinning machine 100 may select a specific slave spinning machine and control only the slave spinning machine. In other words, it is only necessary to transfer data by loading only the slot number of the slave spinning object to be controlled. Of course, in this case, the master spinning machine 100 should include the corresponding slave ID and control command in the control subframe and also include spinner information in the payload subframe.

In this case, one master spinning machine 100 can smoothly control a plurality of slave spinning machines 110, 120, and 130, and since the control method uses a TDMA communication method, More effective control becomes possible.

FIG. 5 is a flowchart showing a process of collecting information on the operation state of a slave spinning machine and a master spinning machine according to the present invention.

The master spinning machine 100 can control the driving state of the slave spinning machines 110, 120, and 130 and various information such as information, etc., in a state where the master spinning machine 100 and the plurality of slave spinning machines 110, 120, It needs to be collected. This is to know whether the spinning process is properly performed in the group.

For this purpose, the master spinning machine 100 and the slave spinning machines 110, 120 and 130 are first set (S150).

At this time, if the master spinner 100 is set as described above among the plurality of individual spinters, the master spinner 100 sets a communication path through a series of networks with the portable terminal device (not shown) (s160).

Then, each of the slave spinning machines 110, 120, and 130 transmits its information to the master spinning machine 100 through the slot allocated by itself through the TDMA communication scheme in a state where the network cycle is periodically executed (s170). The information to be transmitted includes both the process information currently being executed during the whole spinning process, and information on the occurrence of an error.

In this manner, the master spinning machine 100 can receive all the information transmitted from the slave spinning machines 110, 120, and 130. The master spinner 100 can know the status of each of the slave spinners 110, 120 and 130 and the master spinner 100 can notify the manager or user of the information . The information notification can be confirmed through the display unit 114 installed in the master spinning machine 100 (s180).

Of course, the administrator can also confirm the driving state or the error state of the slave spinning machines 110, 120, and 130 through the portable terminal device connected to the master spinning machine 100. That is, when the master spinning machine 100 is set as described above, only the master spinning machine 100 establishes a communication path with the portable terminal device via the network. At this time, the portable terminal device may be various types of portable devices such as a cellular phone and a notebook computer.

Therefore, the master woven machine 100 can provide various kinds of information of the slave textile machines 110, 120 and 130 to the portable terminal device (s190), and even when the manager is absent from the field, It is possible to check the operation states of the slave textile machines 110, 120,

As described above, the present embodiment provides a technical point that a master spinning machine and a remaining slave spinning machines can exchange information by using a TDMA communication method in a spinning mill where a plurality of spinning machines are provided.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It will be apparent that modifications, variations and equivalents of other embodiments are possible. Therefore, the true scope of the present invention should be determined by the technical idea of the appended claims.
