Server H controls the data processing operations of the system when these peripheral devices are operated. However, computer networks are well-known for use in point-of-sale systems. These computer networks typically use standard computer components at each node of the point-of-sale system (see Figure 1). Some systems further include a complex and expensive server and hardware for implementing a software network communication management system to control communication connections with each node of the system. In addition, each-node typically needs to match network communication software and hardware, which increases the cost of the entire system. This network phasing (t0p0gy), which is accustomed to the standard computer data network, generates serious costs and processing expenses, which causes a burden on the point of sale system. (Printed by C. Please read the notes on the back and fill in this page.) In: X Traditional PC-based point-of-sale system, which is used to receive most peripheral components required for reception. The number of standard input / output ports is obviously limited significantly. Today, many different structures exist to overcome this shortage of input / output ports. However, these solutions typically require the addition of specialized hardware 'like special port concentrator units or% cards. These hardware add-ons not only increase the cost of the entire system, but also increase the burden on software developers. 'Software developers must write special application software, which will not cause — — Page 4 This paper Chinese National Standards (CNS) A4 Examination (by Xunfu and public works) ----- 4 4 07 7 2 A7 V. Description of the invention (2 ~ Input / output address and interrupt request (IRQ) number dual use of data conflict problem under the previous topic, Write the address of this plus non-standard input / wheel out port. Another problem related to the conventional point of sale system is that different peripheral devices have different interface requirements. Therefore, a single peripheral device can be directly connected to a computer Other peripheral devices may require a separate interface box to convert their output data into a format suitable for the computer. Furthermore, each input device requires a single software identification number and interrupts the communication between the computer and the device. This In order to generate considerable hardware costs, and each peripheral device added to the system requires more physical space. Therefore, 'there still exists in the field of point of sale system and other suitable The special requirements of the system choose the needs of the computer network. The purpose of the present invention is to improve the decentralized computer network used together with the network system. 15 Another purpose of the present invention is to provide A decentralized computer network that allows most peripherals to connect to the limited number of input / output ports available 5 10

Explanation of the invention (6) The related disadvantages have been discussed previously. Figure 2 generally illustrates a block diagram of a decentralized computer network formed in accordance with the present invention. Referring to Figure 2, the computer network includes a conventional computer network server 2 for executing application software that controls the entire system. The server 2 is best able to cooperate with the traditional 5 [winner is made by IBM or its equivalent. The server 2 communicates with a decentralized network through an i-serial communication port. It is better to integrate an RS-232 port to the server 2. The decentralized computer network of the present invention further includes a main controller 4 /, preferably a hardware base. The main controller 4 is used as a contact point of the interface 10 of the decentralized computer network to communicate with the server 2 and receive instructions from the server 2. It is best that the main controller 4 uses an RS-232 The communication cable is connected to the server 2. The main controller preferably converts the received serial communication from the server 2 into a multipoint branch line communication protocol, and more preferably an RS-485 protocol for distribution along the network. On the other hand, other serial communication formats already familiar to the 15 artists are used in the main controller 4 to convert the serial protocol used for communication connection with the server 2 to use with the computer network Agreement on communication connection with other nodes. The main controller 4 further performs protocol management functions including error detection / correction, data converging arbitration, data buffering, and hardware peripheral drivers. By using the functions in these main controllers 4 instead of the server 2, the server 2 relieves the burdensome communication network control work 'and therefore can operate in a faster and more efficient state. Such use is close to an RS-485 system, for example, a serial data communication or a data rate of 1, 15 200 baud or higher can be achieved.

Description of Invention (//) Meets the power requirements of the point of sale system. The operation of the input / output unit to control the input is the best environmental control, which can upgrade the system and enhance the system's plasticity. = In a preferred embodiment of the present invention, each input / output controller is preferably capable of supporting most peripheral devices at the point of sale by using a universal code cable and peripheral expansion technology. The peripheral device expansion technology is described and described in US Patent Application Serial No. 08 / 011,461 filed on January 26, 1993 by the same inventor (now abandoned). The previous application is for reference only. See "Monthly Reference No. 7 ®", which shows a conventional technology system where a point of sale is connected to a personal computer (PC) workstation (see Figure 1). Using this technology, each peripheral device needs a separate interface card. Therefore, the number of devices supported by a particular personal computer workstation is limited by the number of available slots in that workstation to receive interface cards. In addition, adding or removing an interface card requires partial disassembly of the computer, resetting the software, and restarting the system, thereby increasing the downtime of the system. In FIG. 8, according to one of the peripheral expansion technologies shown in the present invention, the input peripheral device 40 (such as a bar code reader, a point of sale control, 'electronic chip scale' magnetic strip reader, etc.) is preferably The keyboard cock 34 connected to the input / output controller 6 in a daisy wreath structure, and the output peripheral f 38 (such as a pole display, video monitor, printer, etc.) are preferably connected to the input / output control.器 6 的 串 tical port 36. Furthermore, only two input / output bees named keyboard port 36 and serial port 38 are used to support many peripheral devices.

In the keyboard chain of this device, an RS-232 input eight peripheral device 40 (or other peripheral device that does not need to output data in keyboard format) can best use a smart keyboard wedge interface to cooperate with the point of sale system. The 5-keyboard wedge-shaped interface converts the serial data format of the input device 40 into a standard keyboard data format. Generally speaking, the actual location of the input peripheral device is not critical. However, <Because the traditional 101-key computer keyboard does not have a wedge-shaped interface (Because its input is already in the standard keyboard data format> / It is best connected as the last component of such a device chain./ The wedge interface 10 can be part of the device's network connection (that is, external to the input Peripheral device 40) | Or it can be optionally integrated into the input device 40, as shown in Fig. 9 1 Please refer to Fig. 9 f.
