It is the third-generation main computer input device after the keyboard and mouse. From the most direct pictures, photos, films to various drawings, graphics, and document materials, they can all be input into the computer by a barcode scanner, and then the processing, management, use, storage, or output of these image information can be realized.

[0003] The existing barcode scanner circuits generally have only one-way data transmission function. Once the one-way data transmission function is damaged, it cannot be used normally, and the use effect is poor. Content of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings that the existing barcode scanner circuits generally have only one-way data transmission function, and cannot be used normally once the one-way data transmission function is damaged, and the use effect is poor, and a barcode scanner circuit with a multi-channel data transmission function is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A barcode scanner circuit with a multi-channel data transmission function includes:

[0007] A power supply U for supplying power to the overall circuit. The positive pole of the power supply U is connected to a first switch K1;

[0008] A bridge rectifier DC for circuit rectification to obtain direct current and avoid the influence of alternating current waves on use. One pin of the bridge rectifier DC is connected to the first switch K1;

[0009] A barcode scanning camera for performing two-dimensional code scanning and information collection. The positive pole line of the barcode scanning camera is connected to the bridge rectifier DC, and three data transmission channels are connected to the negative pole line of the barcode scanning camera;

[0010] An IC chip for data processing, control, and transmission. The three data transmission channels are all connected to the IC chip. An LED indicator light is connected to the IC chip, and the LED indicator light is connected to the negative pole of the power supply U to form a loop. A terminal display, a barcode scanner display screen, and a wireless transmitter are connected to the IC chip, and the wireless transmitter is wirelessly connected to a mobile terminal.

[0011] Preferably, the three data transmission channels are sequentially connected to the terminal display, the barcode scanner display screen, and the wireless transmitter through the IC chip.

[0012] Preferably, the data transmission channel includes a second switch K2, a resistor R, two DTE converters, two DCE converters, a diode Z, and a buzzer B. The second switch K2 is connected to the resistor R. The two DTE converters and the two DCE converters are connected between the resistor R and the diode Z. The diode Z is connected to the buzzer B.

[0013] Preferably, the two DTE converters and the two DCE converters are connected in series in the circuit, and the sequential connection order is DTE converter, DCE converter, DCE converter, DTE converter. The DTE converter is used to transmit binary data signals, while the DCE is a device capable of sending and receiving data in the form of analog or digital signals through a network. The DCE converts the data from the DTE into a format that can be transmitted on the data circuit and sends the converted signal to another DCE on the network. The main function of the DCE is to achieve signal transformation, encoding, and decoding. At the sending end, it transforms the binary data signals sent by the DTE into line signals suitable for channel transmission requirements, and if necessary, encodes the binary data sequence sent by the DTE before the transformation to improve its anti-interference ability or transmission efficiency. At the receiving end, the opposite transformation is performed to restore the line signals received from the channel into binary data signals. If there is an encoding process at the sending end, a corresponding decoding process is also required at the receiving end to restore the original binary data sequence.

[0014] Preferably, one pin of the bridge rectifier DC is grounded to GND.

[0015] In the present utility model, the beneficial effects of the bar code scanner circuit with a multi-channel data transmission function are as follows:

[0016] In this solution, the three data transmission channels sequentially transmit data to the terminal display, the bar code scanner display, and the wireless transmitter through the IC chip. The wireless transmitter transmits the data to the mobile terminal wirelessly. The mobile terminal is a bar code scanning mobile phone. Three second switches K2 are provided on the three data channels, and the three second switches K2 can be turned on simultaneously or selectively.

[0017] This solution collects data information, performs binary conversion, data transmission, and signal amplification through two DTE converters and two DCE converters, and then transmits it to the IC chip. The IC chip sends the three-way data to the terminal display, the bar code scanner display, and the wireless transmitter respectively. If any one of the three data channels fails, the corresponding buzzer B will give an alarm, and it can be turned off through the second switch K2 without affecting normal use.

[0018] The utility model is provided with three data transmission channels, which can transmit data in three paths. Moreover, if any one of the three data channels fails, it can be closed through the second switch K2 without affecting normal use. Description of the Drawings
