[0043] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above drawings are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily need to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0045] Figure 1 It is a flowchart of an optical disc quantity detection method provided by an embodiment of the present invention. This embodiment is applicable to the situation of detecting the quantity of optical discs in an optical disc library. Refer to Figure 1, the optical disc quantity detection method includes:

[0046] S110. Determine the device parameters in the transmitting device and the device parameters in the receiving device according to the detection distance relation formula between the transmitting device and the receiving device.

[0047] Specifically, the transmitting device includes, for example, an infrared emitting diode, and the receiving device includes, for example, an infrared receiving diode. The transmitting device can emit a first signal in a direct radiation manner, and the receiving device can receive the first signal. When there is no obstacle between the transmitting device and the receiving device, the receiving device can receive the first signal. When there is an obstacle between the transmitting device and the receiving device, the receiving device cannot receive the first signal. Therefore, it can be determined whether there is an optical disc between the transmitting device and the receiving device according to whether the receiving device receives the first signal. By arranging a plurality of transmitting devices and a plurality of receiving devices on the optical disc barrel, the height of the optical discs in the optical disc barrel can be judged, so as to determine the optical disc quantity range in the optical disc barrel.

[0048] The detection distance ranges of the transmitting device and the receiving device are different in different test occasions and for different test objects. Therefore, the control device determines the device parameters in the transmitting device and the device parameters in the receiving device according to the detection distance relation formula between the transmitting device and the receiving device, so that the detection distance between the transmitting device and the receiving device and the signal intensity of the first signal emitted satisfy the requirements of the optical disc barrel, so as to accurately detect the optical disc quantity range in the optical disc barrel.

[0049] S120. Determine the transmitting circuit according to the device parameters of the transmitting device, and determine the receiving circuit according to the device parameters of the receiving device; wherein, the transmitting circuit includes a plurality of transmitting devices, and the receiving circuit includes a plurality of receiving devices; wherein, the transmitting device is configured to emit a first signal, and the receiving device is configured to emit a second signal when the first signal is received, and emit a third signal when the first signal is not received.

[0050] Specifically, Figure 2 is a schematic structural diagram of an optical disc library provided by an embodiment of the present invention. The optical disc library includes an optical disc barrel 200, a transmitting circuit 110 and a receiving circuit 120. The optical disc barrel 200 can accommodate optical discs. The optical discs can be put into the optical disc barrel 200 from the top and sent out from the bottom of the optical disc barrel 200. The corresponding devices of the transmitting circuit 110 and the receiving circuit 120 are in the diameter direction of the optical disc barrel 200. The transmitting circuit 110 includes a plurality of transmitting devices 101, and the receiving circuit 120 includes a plurality of receiving devices 102. After determining the device parameters of the transmitting device 101 and the device parameters of the receiving device 102, the control device can determine the transmitting circuit 110 and the receiving circuit 120.

[0051] The transmitting device 101 and the receiving device 102 are correspondingly arranged in the diametrical direction of the optical disc barrel 200. The transmitting device 101 can transmit the first signal in a direct radiation manner. The first signal is, for example, an infrared signal. The receiving device 102 correspondingly arranged with the transmitting device 101 can receive the first signal transmitted by the transmitting device 101. When the height of the optical disc in the optical disc barrel 200 exceeds the heights of the transmitting device 101 and the receiving device 102, the optical disc blocks the receiving device 102 from receiving the first signal, causing the receiving device 102 not to receive the first signal, and the receiving device 102 will emit a third signal; when the height of the optical disc in the optical disc barrel 200 is less than the heights of the transmitting device 101 and the receiving device 102, the optical disc cannot block the receiving device 102 from receiving the first signal, enabling the receiving device 102 to receive the first signal, and the receiving device 102 will emit a second signal.

[0052] S130. Determine the number range of the optical discs in the optical disc barrel according to the second signal or the third signal.

[0053] Specifically, referring to Figure 2 , the second signal is, for example, a low-level signal. When the control device receives the second signal, it can know that the height of the optical disc does not exceed the heights of the transmitting device 101 and the receiving device 102, and can know the number range of the optical discs; the third signal is, for example, a high-level signal. When the control device receives the third signal, it can know that the height of the optical disc exceeds the heights of the transmitting device 101 and the receiving device 102, and can know the number range of the optical discs.

[0054] Exemplarily, the optical disc quantity detection device includes, for example, five transmitting devices 101 and five receiving devices 102. From the bottom to the top of the optical disc barrel 200, the first transmitting device 101 to the fifth transmitting device 101 are arranged in sequence. That is, the first transmitting device 101 is the transmitting device 101 closest to the bottom of the optical disc barrel 200. The height of the first transmitting device 101 from the bottom of the optical disc barrel 200 is the first preset height. The first receiving device 102 is correspondingly arranged on the other side of the optical disc barrel 200, and the height of the first receiving device 102 from the bottom of the optical disc barrel 200 is the first preset height. That is, the connection line between the transmitting device 101 and the receiving device 102 is parallel to the bottom of the optical disc barrel 200. When the height of the optical discs in the optical disc barrel 200 is less than the first preset height, the optical discs cannot block the first receiving device 102 from receiving the first signal emitted by the first transmitting device 101. When the first receiving device 102 receives the first signal emitted by the first transmitting device 101, the first receiving device 102 will emit a second signal. The control device will then know that the optical disc height is less than the first preset height, will know the optical disc quantity range, and thus know that the optical disc quantity is small, and will remind the user that the optical disc quantity is insufficient, so that the user can add optical discs in time. The fifth transmitting device 101 is the transmitting device 101 closest to the top of the optical disc barrel 200. The height of the fifth transmitting device 101 from the bottom of the optical disc barrel 200 is the second preset height. The fifth receiving device 102 is correspondingly arranged on the other side of the optical disc barrel 200, and the height of the fifth receiving device 102 from the bottom of the optical disc barrel 200 is the second preset height. When the height of the optical discs in the optical disc barrel 200 is greater than the second preset height, the optical discs block the fifth receiving device 102 from receiving the first signal emitted by the fifth transmitting device 101. The fifth receiving device 102 cannot receive the first signal, and the fifth receiving device 102 will emit a third signal. When the control device receives the third signal from the fifth receiving device 102, it will know that the optical disc height is greater than the second preset height, will know the optical disc quantity range, and thus know that the optical disc quantity is large, and will remind the user that the optical disc quantity is full, so that the user can know in time that the optical disc quantity is full.

[0055] It should be noted that Figure 2 only the case where the transmitting circuit 110 includes five transmitting devices 101 and the receiving circuit 120 includes five receiving devices 102 is shown in

[0056] In the technical solution of this embodiment, by determining the device parameters in the transmitting device and the device parameters in the receiving device according to the detection distance relationship between the transmitting device and the receiving device, it can be ensured that the device parameters in the transmitting device and the device parameters in the receiving device meet the detection requirements of the optical disc cartridge, so that the detection distance between the transmitting device and the receiving device and the signal strength of the first signal transmitted can meet the requirements of the optical disc cartridge, the number range of optical discs can be accurately detected, and the accuracy of optical disc number detection is improved. The corresponding devices of the transmitting circuit and the receiving circuit are in the diameter direction of the optical disc cartridge. The transmitting circuit includes multiple transmitting devices, and the receiving circuit includes multiple receiving devices. After determining the device parameters of the transmitting device and the device parameters of the receiving device, the control device can determine the transmitting circuit and the receiving circuit. The transmitting device and the receiving device are correspondingly arranged in the diameter direction of the optical disc cartridge. The transmitting device can transmit the first signal in a direct light way, and the receiving device correspondingly arranged with the transmitting device can receive the first signal transmitted by the transmitting device. When the height of the optical discs in the optical disc cartridge exceeds the heights of the transmitting device and the receiving device, the optical discs block the receiving device from receiving the first signal, so that the receiving device cannot receive the first signal, and the receiving device will send out a third signal; when the height of the optical discs in the optical disc cartridge is less than the heights of the transmitting device and the receiving device, the optical discs cannot block the receiving device from receiving the first signal, so that the receiving device can receive the first signal, and the receiving device will send out a second signal. The second signal is, for example, a low-level signal. When the control device receives the second signal, it can know that the height of the optical discs does not exceed the heights of the transmitting device and the receiving device, and can know the number range of the optical discs; the third signal is, for example, a high-level signal. When the control device receives the third signal, it can know that the height of the optical discs exceeds the heights of the transmitting device and the receiving device, and can know the number range of the optical discs. The technical solution of this embodiment solves the problem that the number of optical discs is determined by the manipulator method, but the error is large and it is difficult to accurately detect the number of optical discs, and achieves the effect of improving the accuracy of optical disc number detection.

[0057] On the basis of the above implementation scheme, Figure 3 is a schematic circuit structure diagram of the transmitting circuit and the receiving circuit provided by an embodiment of the present invention. Optionally, referring to Figure 3 , the receiving device 102 includes an infrared receiving tube D1 and a first resistor R1. The first end of the first resistor R1 is connected to the power supply signal V1, the second end of the first resistor R1 is electrically connected to the cathode of the infrared receiving tube D1, and the anode of the infrared receiving tube D1 is grounded; the transmitting device 101 includes a second resistor R2 and an infrared transmitting tube D2; the first end of the second resistor R2 is connected to the power supply signal V1, the second end of the second resistor R2 is electrically connected to the anode of the infrared transmitting tube D2, and the cathode of the infrared transmitting tube D2 is grounded;

[0058] The detection distance relationship is where D is the detection distance, λ p1is the peak value of the signal emitted by the transmitting device 101, λ p2 is the peak value of the signal received by the receiving device 102, R pT is the resistance value of the first resistor R1, R IR is the resistance value of the second resistor R2.

[0059] Specifically, the detection distance D between the transmitting device 101 and the receiving device 102 and the peak value λ of the signal emitted by the transmitting device 101 p1 , the peak value λ of the signal received by the receiving device 102 p2 , the resistance value R of the first resistor R1 pT and the resistance value R of the second resistor R2 IR are related. Therefore, after the infrared transmitting tube D2 and the infrared receiving tube D1 are determined, the peak value λ of the signal emitted by the transmitting device 101 p1 and the peak value λ of the signal received by the receiving device 102 p2 can be determined. Then, the resistance value R of the first resistor R1 and the resistance value R of the second resistor R2 pT can be determined according to the required detection distance and the detection distance relationship formula, IR so as to determine the device parameters in the transmitting device 101 and the device parameters in the receiving device 102.

[0060] It should be noted that, Figure 3 only shows the case where the transmitting circuit 110 includes two transmitting devices 101 and the receiving circuit 120 includes two receiving devices 102, but it is not limited.

[0061] On the basis of the above embodiments, Figure 4 is a flowchart of another optical disc quantity detection method provided by an embodiment of the present invention. Refer to Figure 4 , this optical disc quantity detection method includes:

[0062] S210. Determine the resistance values of the first resistor and the second resistor according to the detection distance relationship formula between the transmitting device and the receiving device.

[0063] Specifically, when the infrared transmitting tube D2 and the infrared receiving tube D1 are determined, the peak value λ of the signal emitted by the transmitting device p1 can be determined. According to the detection distance relationship formula and the required detection distance, the resistance value R of the first resistor R1 pT and the resistance value R of the second resistor R2 IR, the required detection distance is, for example, the diameter of the disc barrel, or can be the diameter of the disc barrel plus a preset value, so as to ensure that when there is no disc obstruction, the receiving device can receive the first signal emitted by the corresponding transmitting device, which can avoid misjudgment caused by the receiving device not receiving the first signal due to insufficient detection distance, thereby improving the accuracy of disc quantity detection and the reliability of disc quantity detection.

[0064] Among them, the preset value can be a specific numerical value or a numerical range. The specific preset value can be determined according to the actual situation and is not limited here.

[0065] S220. Determine the transmitting circuit according to the device parameters of the transmitting device, and determine the receiving circuit according to the device parameters of the receiving device; among them, the transmitting circuit includes multiple transmitting devices, and the receiving circuit includes multiple receiving devices; among them, the transmitting device is configured to transmit the first signal, and the receiving device is configured to emit the second signal when receiving the first signal and emit the third signal when not receiving the first signal.

[0066] S230. Determine the disc quantity range in the disc barrel according to the second signal or the third signal.

[0067] S240. Send an alarm control signal according to the disc quantity range.

[0068] Specifically, for example, the transmitting circuit 110 includes five transmitting devices 101, and the receiving circuit 120 includes five receiving devices 102. From the bottom to the top of the disc barrel 200, the first transmitting device 101 to the fifth transmitting device 101 are arranged in sequence. When the first receiving device 102 receives the first signal emitted by the first receiving device 102, the first receiving device 102 will emit the second signal, and the control device will know that the disc height is less than the first preset height, will know the disc quantity range, and thus know that the disc quantity is small, and will send the first alarm control signal, causing the alarm device to emit the first alarm signal, such as ringing three times, so as to remind the user that the disc quantity is insufficient, enabling the user to add discs in time; when the fifth receiving device 102 emits the third signal and the control device receives the third signal of the fifth receiving device 102, it will know that the disc height is greater than the second preset height, will know the disc quantity range, and thus know that the disc quantity is large, and will send the second alarm control signal, causing the alarm device to emit the second alarm signal, such as ringing five times, so as to remind the user that the disc quantity is full, enabling the user to know in time that the disc quantity is full.

[0069] Based on the above technical solution, Figure 5 is a flowchart of another disc quantity detection method provided by an embodiment of the present invention. Optionally, refer to Figure 5 , this disc quantity detection method includes:

[0070] S310. Determine the preset detection distance between the receiving device and the transmitting device, and determine the preset intensity of the first signal.

[0071] Specifically, the control device first obtains the preset detection distance between the receiving device and the transmitting device. The preset detection distance is, for example, the sum of the diameter of the disc barrel and a preset value, and determines the preset intensity of the first signal. If the intensity of the first signal is too small, the receiving device may sometimes receive the first signal and sometimes not, which is extremely unstable. And since the disc has the ability to reflect light, if the intensity of the first signal is too large, it is likely to cause false triggering. Therefore, determining the preset detection distance and the preset intensity of the first signal can avoid misjudgment caused by the receiving device not receiving the first signal due to insufficient detection distance, thereby improving the accuracy of disc quantity detection.

[0072] Among them, the preset intensity of the first signal can be a specific intensity value or an intensity range. The specific preset intensity can be determined according to the actual situation and is not limited here.

[0073] S320. Determine the resistance value of the first resistor and the resistance value of the second resistor according to the preset detection distance, the preset intensity, and the detection distance relationship formula.

[0074] Specifically, when the infrared emitting diode D2 and the infrared receiving diode D1 are determined, the peak value λ of the signal emitted by the transmitting device p1 can be determined. According to the detection distance relationship formula and the preset detection distance, the initial resistance value of the first resistor R1 and the initial resistance value of the second resistor R2 can be determined. After determining the transmitting circuit and the receiving circuit according to the initial resistance value of the first resistor R1 and the initial resistance value of the second resistor R2, use the transmitting circuit and the receiving circuit to detect the disc quantity range of the disc barrel, and at the same time measure the current intensity of the first signal emitted by the transmitting circuit. If the current intensity meets the preset intensity, then the initial resistance value of the first resistor R1 can be determined as the resistance value R pT of the first resistor R1 and the resistance value R IR of the second resistor R2; if the current intensity does not meet the preset intensity, then adjust the initial resistance value of the first resistor R1 and the initial resistance value of the second resistor R2, and actually measure the current intensity of the first signal until the current intensity of the first signal meets the preset intensity, and then the resistance value R pT of the first resistor R1 and the resistance value R IR of the second resistor R2 can be determined, thereby ensuring that the receiving device stably receives the first signal emitted by the corresponding transmitting device.

[0075] S330. Determine the transmitting circuit according to the device parameters of the transmitting device, and determine the receiving circuit according to the device parameters of the receiving device. Among them, the transmitting circuit includes multiple transmitting devices, and the receiving circuit includes multiple receiving devices. Among them, the transmitting device is configured to transmit a first signal, and the receiving device is configured to emit a second signal when the first signal is received and emit a third signal when the first signal is not received.

[0076] S340. Determine the range of the number of optical discs in the disc barrel according to the second signal or the third signal.

[0077] S350. Send an alarm control signal according to the range of the number of optical discs.

[0078] S360. Send the range of the number of optical discs to the display device so that the display device can display the range of the number of optical discs.

[0079] Specifically, after the control device determines the range of the number of optical discs, it can send the range of the number of optical discs to the display device, so that the display device can display the range of the number of optical discs in real time, facilitating the user to know the range of the number of optical discs in real time.
