[0002] With the development of automation technology, more and more self-service terminal products are deployed in the streets and alleys. Many self-service terminal devices use moving parts or high-heat modules inside to achieve corresponding functions, such as linear, swinging, high-speed rotating, compressing and other motions. Under normal circumstances, such terminal devices will have certain protection measures, but when certain functions of the device fail or the device is maintained, there is still a risk of causing personal mechanical injuries.

[0003] The purpose of this solution is to provide a control protection solution, which can greatly reduce the personal injuries caused by the failure of the control logic or the illegal operation of the device maintenance personnel during device maintenance. Summary of the Invention

[0004] The technical problem solved by the present invention is to provide an intelligent terminal control protection system that reduces personal injuries caused by software logic failure or illegal operation of maintenance personnel.

[0005] The technical solution adopted by the present invention to solve its technical problems is: an intelligent terminal control protection system, including a system power supply, a sensor, a relay and a module power supply. The input end of the system power supply is used to connect to an external power supply, the output end of the system power supply is used to connect to the main control system of the intelligent terminal, the output end of the system power supply is connected to the power supply end of the sensor, the signal output end of the sensor is connected to the signal control end of the relay, the input end of the relay is connected to the external power supply, and the output end of the relay is connected to the module power supply.

[0006] Further: The sensor is a normally closed sensor. The normally closed sensor is in an open state under normal circumstances, and its internal contacts are not conducting. When the sensor is triggered, the internal contacts close and send a control signal to the relay.

[0007] Further: The relay is a normally closed relay;

[0008] When the normally closed relay does not receive a control signal, its contacts are in a closed state, and the module power supply can supply power to the power module. When the control signal of the sensor is received, the relay contacts open, the module power supply is powered off, and the power module stops working.

[0009] Further: The sensor is a metal proximity sensor, a limit switch, a through-beam sensor or a retroreflective sensor.

[0010] The present invention also discloses a method for controlling and protecting an intelligent terminal, including the intelligent terminal control and protection system described above, and the steps are as follows:

[0011] S100: The self-service terminal is powered on, the system power supply is powered on, and the main control system starts to work;

[0012] S200: The sensor is powered on and enters the normal working state. At this time, the sensor is in the off state, and the control end of the relay is not triggered;

[0013] S300: The relay is in the connected state, the module power supply is powered on, and the power module works normally;

[0014] S400: When the maintenance door of the intelligent terminal is opened, the sensor senses the state change, the sensor becomes in the connected state, the control signal of the relay is triggered, the relay is disconnected, the module power supply is disconnected, and the power module is powered off.

[0015] The present invention also discloses an intelligent terminal, including an intelligent terminal body. The intelligent terminal body includes a device door. Inside the intelligent terminal body, there are a system power supply, a sensor, a relay, a module power supply, a main control system, and multiple power modules. The sensor is installed inside. When the device door is opened and an external object enters through the device door, the sensor receives a signal;

[0016] The input end of the system power supply is used to connect to an external power supply. The output end of the system power supply is connected to the main control system. The output end of the system power supply is connected to the power supply end of the sensor. The signal output end of the sensor is connected to the signal control end of the relay. The input end of the relay is connected to an external power supply. The output end of the relay is connected to the module power supply.

[0017] Furthermore: The sensor is a normally closed sensor. The normally closed sensor is in the off state under normal circumstances, and its internal contacts are not conducting. When the sensor is triggered, the internal contacts close and send a control signal to the relay.

[0018] Furthermore: The relay is a normally closed relay;

[0019] When the normally closed relay does not receive a control signal, its contacts are in the closed state, and the module power supply can supply power to the power module. When it receives the control signal of the sensor, the relay contacts open, the module power supply is powered off, and the power module stops working.

[0020] Furthermore: The sensor is a metal proximity sensor, a limit switch, a through-beam sensor, or a reflective sensor.

[0021] The beneficial effects of the present invention are:

[0022] 1. This solution separates the system power supply from the module power supply. Through the combination of an inductor and a relay, it realizes the forced power-off of high-power dangerous modules, greatly reducing the personal injuries caused by software logic failure or maintenance personnel's illegal operations during equipment maintenance.

[0023] 2. The solution uses a normally closed inductor and a relay with a normally closed contact. In the normal working state, the control coil of the relay has no voltage, so there is no loss. It is only energized during maintenance. Therefore, this solution can effectively reduce power consumption.

[0024] 3. The inductor in this solution can be selected from various types such as metal proximity sensors, limit switches, through-beam sensors, or retroreflective sensors, etc. It has high flexibility and adaptability, and can be selected according to different intelligent terminal devices and application scenarios, improving the versatility and practicality of the solution.

[0026] Figure 1 It is a schematic framework diagram of the intelligent terminal control and protection system according to the embodiment of the present application.

[0027] Figure 2 It is a schematic flow diagram of the intelligent terminal control and protection method according to the embodiment of the present application. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be given with reference to the accompanying drawings.

[0029] As Figure 1 shown, the embodiment of the present application discloses an intelligent terminal control and protection system, including a system power supply, an inductor, a relay, and a module power supply. The input end of the system power supply is used to connect to an external power supply, the output end of the system power supply is used to connect to the main control system of the intelligent terminal, the output end of the system power supply is connected to the power supply end of the inductor, the signal output end of the inductor is connected to the signal control end of the relay, the input end of the relay is connected to the external power supply, and the output end of the relay is connected to the module power supply.

[0030] Specifically, the above-mentioned module power supply is used to supply power to the power module. The power module is the core component for realizing various functions inside the self-service terminal device, including but not limited to the motor drive module, heating module, cooling module, etc. These power modules may generate high heat or high-speed movement during operation. Therefore, it is crucial to supply power to and control them safely and reliably.

[0031] Specifically, during operation, the system power supply is used to provide stable power supply for the entire system to ensure the normal operation of each component. The sensor, as a detection device, can monitor the status change of the door of the intelligent terminal device in real time. When the device door is opened, the sensor can quickly sense and respond. The relay acts as a switch to control the on and off of the module power supply according to the signal of the sensor. The module power supply is responsible for supplying power to the power module inside the intelligent terminal. When the relay is disconnected, the module power supply will also be powered off accordingly, so as to ensure that the power module stops working and avoid potential dangers.

[0032] This solution separates the system power supply and the module power supply. Through the combination of the sensor and the relay, it realizes the forced power-off of high-power dangerous modules, greatly reducing the personal injuries caused by software logic failure or maintenance personnel's illegal operations during equipment maintenance.

[0033] In this embodiment, the sensor is a normally closed sensor, and the relay is a normally closed relay.

[0034] Specifically, the normally closed sensor is in an open state under normal circumstances, that is, when there is no external object triggering, its internal contacts are not conducting. The advantage of this design is that only when the device door is opened and the sensor is triggered, its internal contacts will close, thereby sending a control signal to the relay. The normally closed relay has its contacts in a closed state when it does not receive a control signal, enabling the module power supply to supply power to the power module normally. Once it receives the control signal from the sensor, the relay contacts disconnect, the module power supply is powered off, and the power module stops working.

[0035] In addition, the combined use of the normally closed sensor and the relay can also improve the safety of the system to a certain extent. Because even in the case of software logic failure, as long as the device door is opened, the sensor can still trigger the relay to act and realize the power-off protection of the module power supply. This hardware-level safety protection measure provides a more reliable safety guarantee for the intelligent terminal device.

[0036] Specifically, the sensor is a metal proximity sensor, limit switch, opposed sensor, reflective sensor, etc. These types of sensors have their own characteristics and can be selected according to the specific requirements and application scenarios of the intelligent terminal device, thereby improving the versatility and practicality of the solution.

[0037] The present invention also discloses a method for controlling and protecting an intelligent terminal, including the intelligent terminal control and protection system described above, and the steps are as follows:

[0038] S100: The self-service terminal is powered on, the system power supply is powered on, and the main control system starts to work;

[0039] S200: The sensor is powered on and enters the normal working state. At this time, the sensor is in the off state, and the control end of the relay is not triggered;

[0040] S300: The relay is in the connected state, the module power supply is powered on, and the power module works normally;

[0041] S400: The maintenance door of the intelligent terminal is opened, the sensor senses the state change, the sensor becomes the connected state, the control signal of the relay is triggered, the relay disconnects, the module power supply disconnects, and the power module is powered off.

[0042] Specifically, during the repair or maintenance of the intelligent terminal, when the maintenance door is opened, the sensor will immediately sense this state change and quickly change from the off state to the connected state. This change will immediately trigger the control signal of the relay, causing the relay to change from its original connected state to the off state. With the disconnection of the relay, the module power supply will also be disconnected, and then the power module connected thereto will lose power supply and stop working. This series of reactions are completed in a very short time, so as to ensure that when the maintenance door is opened, the potential dangerous power module can quickly cut off the power, greatly reducing the risk of safety accidents caused by human misoperation or software logic failure.

[0043] The present invention also discloses an intelligent terminal, including an intelligent terminal body. The intelligent terminal body includes a device door. Inside the intelligent terminal body, there are a system power supply, a sensor, a relay, a module power supply, a main control system, and a plurality of power modules. The sensor is installed inside. When the device door is opened and an external object enters through the device door, the sensor receives a signal;

[0044] The input end of the system power supply is used to connect to an external power supply. The output end of the system power supply is connected to the main control system. The output end of the system power supply is connected to the power supply end of the sensor. The signal output end of the sensor is connected to the signal control end of the relay. The input end of the relay is connected to an external power supply. The output end of the relay is connected to the module power supply.

[0045] Specifically, the system power supply inside the intelligent terminal body is responsible for providing stable power supply for the entire intelligent terminal to ensure the normal operation of each component. The sensor is installed inside the device door to monitor the status change of the device door in real time. Once the device door is opened, the sensor can quickly capture this change and immediately respond. When the sensor senses that the device door is opened, it will immediately send a control signal to the relay, and the relay will quickly respond and disconnect the connection with the module power supply, so as to ensure that the power module can immediately stop working and avoid possible dangers.

[0046] Specifically, the existing products are based on the detection and control scheme of the control board. When the control board functions normally, it can play a protective role. However, when the control board is abnormal, there is a risk of being out of control. And this scheme realizes a forced power-off scheme through the sensor and the relay, which greatly reduces the personal injury caused by software logic failure or maintenance personnel's illegal operation.

[0047] In this embodiment, the sensor is a normally closed sensor, the relay is a normally closed relay, and the sensor is a metal proximity sensor, a limit switch, a through-beam sensor, a retroreflective sensor, etc.

[0048] Therefore, the scheme adopts a normally closed sensor and cooperates with a relay with a normally closed contact. In the normal working state, the control coil of the relay has no voltage, so there is no loss, and it will only be powered on during maintenance. Therefore, this scheme can effectively reduce power consumption. At the same time, various types of sensors can be selected for the sensor in this scheme, which has high flexibility and adaptability and can be selected according to different intelligent terminal devices and application scenarios, improving the versatility and practicability of the scheme.

[0049] The specific embodiments described above have further elaborated on the purpose, technical solutions, and beneficial effects of the present invention. It should be understood that the above are only specific embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
