Obviously, the described embodiment is an embodiment of a part of the present solution, not all of the embodiments.

In addition, the terms "first" and "second" are used to distinguish different objects, not to describe a specific order.
[0048] The following is a detailed description of the implementation of the present disclosure in conjunction with the specific drawings:
[0049] Figure 1This is a schematic diagram of the structure of a DC power supply screen touch protection system 10 provided in an embodiment of the present disclosure. Figure 1 The DC power supply screen touch protection system 10 comprises:
[0050] Human body detection module 101, temperature detection module 102, first logic gate module 103, second logic gate module 104, control module 105, first alarm module 106, second alarm module 107;
[0051] The human body detection module 101 and the temperature detection module 102 are both connected to the first logic gate module 103, and the temperature detection module 102 is connected to the second logic gate module 104;
[0052] The control module 105 is respectively connected to the first logic gate module 103, the second logic gate module 104, the first alarm module 106, and the second alarm module 107;
[0053] The human body detection module 101 is configured to detect the status information of people around the DC power supply screen; the temperature detection module 102 is configured to collect the temperature information inside the DC power supply screen;
[0054] The first logic gate module 103 is configured to output different level signals according to the personnel status information and the temperature information; the second logic gate module 104 is configured to output different level signals according to the temperature information;
[0055] The control module 105 is configured to control the working states of the first alarm module 106 and the second alarm module 107 according to different level signals.
[0056] In this embodiment, the human detection module 101 is used to monitor and detect in real time whether there is human activity around the DC power panel. Once it is detected that someone is approaching or touching the power panel, the status information is processed and sent to the first logic gate module 103.
[0057] The temperature detection module 102 is used to continuously collect temperature information inside the DC power supply panel, and the temperature information is sent to the first logic gate module 103 and the second logic gate module 104 after processing. Too high or too low temperature may affect the normal operation of the DC power supply panel.
[0058] The first logic gate module 103 is used to receive signals sent by the human body detection module 101 and the temperature detection module 102 , and output corresponding level signals to the control module 105 according to a preset logic judgment rule.
[0059] The second logic gate module 104 is only used to receive the signal sent by the temperature detection module 102, and when the temperature inside the DC power supply panel exceeds the normal temperature range, it outputs a corresponding level signal to the control module 105. The level signal sent by the second logic gate module 104 and the level signal sent by the first logic gate module 103 are different level signals.
[0060] As the control center of the whole system, the control module 105 can respond to the received signals of different levels and respectively control the working states of the first alarm module 106 and the second alarm module 107. The first alarm module 106 can realize remote alarm, and the second alarm module 107 can realize short-range alarm.
[0061] In this embodiment, the human body detection module 101 and the temperature detection module 102 can process the collected personnel status information and temperature information, and send the processed signals to the first logic gate module 103 and the second logic gate module 104. The first logic gate module 103 can judge the input signal according to the preset logic judgment rule and output the corresponding level signal; the second logic gate module 104 can also judge the input signal according to the preset logic judgment rule and output the corresponding level signal. The control module 105 can judge whether to start the first alarm module 106 and the second alarm module 107 according to the level signals sent by the first logic gate module 103 and the second logic gate module 104.
[0062] The first logic gate module 103 and the second logic gate module 104 can be logic gates such as "AND", "OR", "NOT", etc. For example, the first logic gate module 103 and the second logic gate module 104 are AND gates. The human body detection module 101 can convert the collected personnel status information into a binary logic signal and send the binary logic signal to the first logic gate module 103. When it is detected that someone is approaching or touching the power panel, the binary logic signal can be "1"; when no one is detected approaching, the binary logic signal can be "0".
[0063] The temperature detection module 102 can convert the collected temperature information into a binary logic signal, and send the binary logic signal to the first logic gate module 103 and the second logic gate module 104. For example, if the temperature value is within the normal range (0°C~45°C), the binary logic signal can be "1"; if the temperature value is not within the normal range, the binary logic signal can be "0".
[0064] Case 1: The level signal output by the first logic gate module 103 is "1", and the level signal output by the second logic gate module 104 is "1". The control module 105 determines that someone is close to the DC power supply screen based on the two output level signals, and the temperature data inside the DC power supply screen is abnormal, so the first alarm module 106 can be activated to implement remote alarm, and the second alarm module 107 can be activated for short-range alarm. Case 2: The level signal output by the first logic gate module 103 is "0", and the level signal output by the second logic gate module 104 is "0". The control module 105 determines that no one is close to the DC power supply screen based on the two output level signals, and the temperature data inside the DC power supply screen is normal, so there is no need to activate the first alarm module 106 and the second alarm module 107 for alarm.
[0065] Case three: the level signal output by the first logic gate module 103 is "0", and the level signal output by the second logic gate module 104 is "1". The control module 105 determines that no one is close to the DC power supply screen based on these two output level signals, but the temperature data inside the DC power supply screen is abnormal. Therefore, the first alarm module 106 can be activated to issue a remote alarm to remind relevant technicians that a fault has occurred inside the DC power supply screen, so that the technicians can conduct timely inspection and maintenance.
[0066] It can be concluded from the above that the present disclosure detects from the outside and inside of the DC power supply screen respectively. The external human body detection module 101 can determine whether there is a person close to the DC power supply screen, and the internal temperature detection module 102 can determine whether the temperature inside the DC power supply screen is abnormal. It provides comprehensive protection for the personal safety of the staff from both the inside and the outside. In addition, the present disclosure is also provided with a first alarm module 106 and a second alarm module 107. When an abnormality occurs both inside and outside the DC power supply screen, the control module 105 can simultaneously start the remote alarm module and the second alarm module 107 to alarm; when only the DC power supply screen fails, the control module 105 only starts the first alarm module 106 to alarm. The DC power supply screen anti-touch system 10 provided in the embodiment of the present disclosure can solve the problem of staff accidentally touching the DC power supply screen and causing injuries, and alarm possible dangerous situations.
[0067] In one embodiment of the present disclosure, the human body detection module 101 includes:
[0068] Human body detection unit 201, pressure detection unit 202;
[0069] The human body detection unit 201 and the pressure detection unit 202 are both connected to the input end of the first logic gate module 103;
[0070] The human body detection unit 201 is configured to detect first person status information around the DC power supply screen; the pressure detection unit 202 is configured to detect second person status information around the DC power supply screen.
[0071] In this embodiment, the human detection module 101 includes a human detection unit 201 and a pressure detection unit 202. The first person status information may be status information of whether a person is approaching the DC power supply screen, and the second person status information may be whether the DC power supply screen receives the pressure information of the person.
[0072] The human body detection module 101 can detect whether there is a person approaching the DC power screen. When the distance between the person and the DC power screen is within the first distance range, it indicates that the person is close to the DC power screen. When the distance between the person and the DC power screen is not within the first distance range, it indicates that the person is far away from the DC power screen.
[0073] The pressure detection unit 202 can detect whether someone presses the DC power screen. When the pressure of the person pressing the DC power screen is within the first pressure range, it means that someone presses the DC power screen. When the pressure of the person pressing the DC power screen is not within the first pressure range, it means that no one presses the DC power screen.
[0074] For example, the first distance range is 0~1m, and the first pressure range is 30N~200N. When the human body detection module 101 detects that the first distance between a person and the DC power supply screen is 0.5m, the human body detection module 101 determines that a person is close to the DC power supply screen and outputs a binary logic signal "1"; when the human body detection module 101 detects that the first distance between a person and the DC power supply screen is 2m, the human body detection module 101 determines that no person is close to the DC power supply screen and outputs a binary logic signal "0".
[0075] When the pressure detection module detects that the pressure acting on the DC power panel is 100N, it means that someone may have touched and pressed the DC power panel. For example, if someone touches the DC power panel and opens a switch cabinet, the switch cabinet will be pressed by the person's hand. The pressure detection module will output a binary logic symbol "1".
[0076] When the pressure detection module detects that the pressure acting on the DC power supply screen is 10N, it means that no one has touched the DC power supply screen. The pressure value may be detected by wind or animals passing by. At this time, the pressure detection module will output a binary logic symbol "0".
[0077] It can be concluded from the above that the human detection module 101 and the pressure detection module can respectively detect whether someone is close to the DC power supply screen and whether someone presses the DC power supply screen, which helps to divide the status information of the personnel more finely, thereby providing a basis for subsequent processing.
[0078] In one embodiment of the present disclosure, the first logic gate module 103 includes:
[0079] A first logic gate unit 203, a second logic gate unit 204;
[0080] The input end of the first logic gate unit 203 is connected to the human body detection unit 201, the pressure detection unit 202, and the temperature detection module 102 respectively, and the output end of the first logic gate unit 203 is connected to the control module 105;
[0081] The input end of the second logic gate unit 204 is connected to the human body detection unit 201 and the pressure detection unit 202 respectively, and the output end of the second logic gate unit 204 is connected to the control module 105;
[0082] The first logic gate unit 203 is configured to output a first level signal according to the binary logic signal sent by the human body detection unit 201, the pressure detection unit 202, and the temperature detection module 102;
[0083] The second logic gate unit 204 is configured to output a second level signal according to the binary logic signal sent by the human body detection unit 201 and the pressure detection unit 202 .
[0084] In this embodiment, the first logic gate unit 203 of the first logic gate module 103 is a multi-input logic gate, which can receive signal inputs from the human detection unit 201, the pressure detection unit 202 and the temperature detection module 102. These units or modules will output corresponding binary logic signals according to the on-site conditions. The on-site conditions can be whether a person is approaching, whether the device is under excessive pressure, and whether the temperature inside the device is normal; the output binary logic signal can be 1 (representing presence / out of range) or 0 (representing absence / normal).
[0085] The first logic gate unit 203 performs a pre-set logic operation (which may be a logic combination of "AND", "OR", "NOT", etc.) based on these input signals to generate a first level signal. The first level signal may represent a comprehensive safety state, for example, a specific control action or alarm will be triggered only when a person is close, the pressure is abnormal, and the temperature is abnormal. The second logic gate unit 204 of the second logic gate module 104 receives signals from the human body detection unit 201 and the pressure detection unit 202, which means that it focuses on the two conditions of people approaching and equipment being under pressure. Similarly, the unit performs a logic operation based on the input binary logic signal and outputs a second level signal, which may correspond to another level of safety state, such as triggering another set of control strategies or a separate alarm prompt only when people are close and the equipment is under greater pressure.
[0086] The control module 105 receives the level signals from the first logic gate unit 203 and the second logic gate unit 204 and responds accordingly, such as activating the corresponding alarm module to remind the staff to pay attention to potential dangers, or directly taking measures to adjust the working state of the equipment to ensure safety.
[0087] It can be concluded from the above that the first logic gate unit 203 can output a first level signal according to the signals sent by the human body detection unit 201, the pressure detection unit 202 and the temperature detection module 102, and the second logic gate unit 204 can output a second level signal according to the signals sent by the human body detection unit 201 and the pressure detection unit 202. The control module 105 responds to the first level signal and the second level signal to start the corresponding warning mode.
[0088] In one embodiment of the present disclosure, the control module 105 includes:
[0089] A first comparing unit 205, a second comparing unit 206;
[0090] A first comparison unit 205, a first input end connected to the first logic gate module 103, a second input end connected to an external signal, and an output end connected to the first alarm module 106 and the second alarm module 107;
[0091] The second comparison unit 206 has a first input terminal connected to the second logic gate module 104 , a second input terminal connected to an external signal, and an output terminal connected to the first alarm module 106 .
[0092] In this embodiment, the input end of the first comparison unit 205 is connected to the output end of the first logic gate module 103, and the second input end receives an external reference signal or a preset threshold signal. After the first logic gate module 103 outputs a first level signal based on the data of the human body detection unit 201, the pressure detection unit 202 and the temperature detection module 102, the first comparison unit 205 compares this level signal with the external signal. If the comparison result satisfies the preset logical relationship (for example, greater than, less than or equal to the threshold), the first comparison unit 205 will activate and output the corresponding control signal to the first alarm module 106 and the second alarm module 107, triggering the corresponding alarm or safety protection measures.
[0093] The first input end of the second comparison unit 206 receives the second level signal output by the second logic gate module 104 based on the data of the human body detection unit 201 and the pressure detection unit 202. The second comparison unit 206 compares it with the same or different external signals, and then decides whether to send a signal to the first alarm module 106 according to the comparison result. This design means that once the specific safety condition associated with the second logic gate unit 204 reaches the preset standard, it can also independently trigger the alarm operation.
[0094] It can be concluded from the above that the control module 105 is further subdivided into two comparison units, which compare the signals generated by the first logic gate module 103 and the second logic gate module 104 with the external signal, so as to achieve a more accurate monitoring and response mechanism.
[0095] In one embodiment of the present disclosure, the first comparison unit 205 includes:
[0096] A first comparator 301 and a second comparator 302;
[0097] A first comparator 301, a first input terminal connected to the first logic gate module 103, a second input terminal connected to an external signal, and an output terminal connected to the first alarm module 106 and the second alarm module 107;
[0098] The second comparator 302 has a first input terminal connected to the first logic gate module 103 , a second input terminal connected to an external signal, and an output terminal connected to the second alarm module 107 .
[0099] In this embodiment, the two input ends of the first comparator 301 are connected to the output end of the first logic gate unit 203 of the first logic gate module 103 and the external signal respectively. When the first logic gate unit 203 outputs the first logic judgment signal according to the status of the human body detection unit 201, the pressure detection unit 202 and the temperature detection module 102, the first comparator 301 will immediately obtain this signal and compare it with the external signal. If the comparison result shows an abnormality, the first comparator 301 will send a signal to the first alarm module 106 and the second alarm module 107 to trigger the corresponding alarm or safety measures.
[0100] The two input ends of the second comparator 302 are respectively connected to the output end of the second logic gate unit 204 of the first logic gate module 103 and the external signal. When the second logic gate unit 204 outputs the second logic judgment signal according to the status of the human body detection unit 201 and the pressure detection unit 202, the second comparator 302 also compares the output signal of the second logic gate unit 204 with the external signal. The output end of the second comparator 302 is connected to the second alarm module 107. When the comparison result is abnormal, the second comparator 302 can activate the second alarm module 107 alone to reflect another specific warning level or emergency. It can be concluded from the above that the first comparison unit 205 is further subdivided into the first comparator 301 and the second comparator 302, which jointly undertake the task of comparing the input signal and drive the alarm module to issue an early warning according to different comparison results.
[0101] In one embodiment of the present disclosure, the DC power supply screen touch protection system 10 further includes:
[0102] A first indicator light 108 and a second indicator light 109;
[0103] A first indicator light 108, a first end of which is connected to the first comparison unit 205, and a second end of which is connected to the first alarm module 106 and the second alarm module 107 respectively;
[0104] The second indicator light 109 has a first end connected to the second comparison unit 206 , and a second end connected to the first alarm module 106 .
[0105] In this embodiment, the first end of the first indicator light 108 is connected to the first comparison unit 205. After the first comparison unit 205 compares the output signal of the first logic gate module 103 with the external signal, if an abnormal situation occurs and the first alarm module 106 or the second alarm module 107 is activated, the first indicator light 108 will also light up accordingly, providing an intuitive visual indication that the system is in a certain warning or abnormal state.
[0106] The first end of the second indicator light 109 is connected to the second comparison unit 206. When the second comparison unit 206 completes the comparison result and determines whether to start the first alarm module 106, the second indicator light 109 will also change accordingly. The second indicator light 109 lights up, indicating that the first alarm module 106 is started, and the second indicator light 109 does not light up, indicating that the first alarm module 106 is not started. It can be concluded from the above that in addition to the original detection module and alarm module, the DC power screen touch protection system 10 also adds a visual indication device, namely the first indicator light 108 and the second indicator light 109, to enhance the status display function of the system.
[0107] In one embodiment of the present disclosure, the DC power supply screen touch protection system 10 further includes:
[0108] A circuit breaker module 110;
[0109] The circuit breaker module 110 is connected to the control module 105, and the circuit breaker module 110 is connected to the output end of the DC power supply panel;
[0110] The circuit breaker module 110 is configured to control the output terminal of the DC power supply panel to be disconnected according to the first signal output by the control module 105 .
[0111] In this embodiment, the circuit breaker module 110 is connected to the control module 105 and receives the command signal sent by the control module 105. When the control module 105 obtains that the device needs to cut off the power supply to ensure safety through the signals sent by the first logic gate module 103 and the second logic gate module 104, the first signal is sent to the circuit breaker module 110. After receiving the signal, the circuit breaker module 110 will respond quickly and execute the action of cutting off the circuit at the output end of the DC power supply panel, thereby preventing the relevant personnel from getting an electric shock.
[0112] It can be concluded from the above that the provision of the circuit breaker module 110 effectively realizes active disconnection of the power supply in extreme or dangerous situations, avoids further safety accidents that may be caused by accidental touch by personnel or equipment failure, and improves the safety protection level of the entire system.
[0113] In one embodiment of the present disclosure, the DC power supply screen touch protection system 10 further includes:
[0114] Reset module 111;
[0115] The reset module 111 is connected to the control module 105, and the reset module 111 is connected to the output end of the DC power supply panel;
[0116] The reset module 111 is configured to control the output terminal connection of the DC power supply panel according to the second signal output by the control module 105 .
[0117] In this embodiment, the reset module 111 is connected to the control module 105 and receives the command signal issued by the control module 105. When the technician eliminates the fault and the DC power supply screen returns to normal, the control module 105 will output a second signal to the reset module 111 according to the specific situation. The reset module 111 performs the operation of restoring the connection of the output end of the DC power supply screen according to the received second signal. It can be concluded from the above that when the abnormal situation detected by the system is resolved, such as the departure of personnel, the return of pressure to normal, and the return of temperature to a safe range, the control module 105 will reconnect the output of the power supply screen through the reset module 111 to ensure that the equipment can continue to operate normally under safe conditions. This design not only ensures the effective protection of the system under abnormal conditions, but also realizes the rapid restoration of power supply after restoration to normal, thereby improving the practicality and safety of the system.
