[0014] In order to make the purpose, technical solutions and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The described embodiments should not be regarded as limiting this application. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0015] In the following description, references to "some embodiments" describe a subset of all possible embodiments. However, it is understood that "some embodiments" may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict. In the following description, the term "plurality" refers to at least two.
[0016] In the following description, the terms "first\second" are only used to distinguish similar objects and do not represent a specific order for the objects. It can be understood that "first\second" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.
[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein are for the purpose of describing the embodiments of this application only and are not intended to limit this application.
[0018] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.
[0019] Industrial production equipment requires a combination of different light sources to perform different types of inspections. For example, when inspecting the surface flatness of an object, industrial production equipment requires a combination of different light sources to capture an image of the object's surface and determine the surface flatness based on the captured image.
[0020] However, because different light sources use different power supply voltages, controllers corresponding to different voltages are required to control the power supply of each light source. This results in a large number of controllers on industrial production equipment, increasing the cost of industrial production equipment. It also puts pressure on the spatial design of industrial production equipment (for example, the placement of the controller and the layout of the connection cables between the controller and the power supply).
[0021] For example, when a group of combined light sources requires light sources with three different power supply voltages of 12V, 24V, and 48V, controllers with these three corresponding voltages need to be selected to drive the group of light sources.
[0022] In order to improve the above problems, the application provides a controller and a detection system, the controller comprising: a programmable power supply, a control module, a conversion module, an output port and an acquisition module, the programmable power supply being connected with the control module and the conversion module, the conversion module being connected with the output port, and the acquisition module being connected with the control module and the output port respectively, wherein: the acquisition module is used for collecting voltage information of an external load through the acquisition module and sending the voltage information to the control module in the case that the output port is connected with the external load; the control module is further used for determining output voltage of the programmable power supply output to the conversion module according to the voltage information and preset comparison information; and the conversion module is used for converting the output voltage into working voltage required by the external load for normal working.
[0023] Thus, the actual situation of the external load is determined through the acquisition module, and then the output voltage of the programmable power supply is adjusted through the conversion module, so that the output voltage of the programmable power supply can supply the external load for normal working.
[0024] For specific implementation details, please continue to refer to the following steps.
[0025] Please refer to Figure 1 and Figure 2 , Figure 1 Fig. 1 shows a structural schematic diagram of a controller provided by an embodiment of the application, Figure 2 Fig. 2 shows a structural schematic diagram of another controller provided by an embodiment of the application. As shown in Figure 1 and Figure 2 , the controller 100 comprises a programmable power supply 101, a control module 102, a conversion module 103, an output port 104 and an acquisition module 105, the programmable power supply 101 being connected with the control module 102 and the conversion module 103, the conversion module 103 being connected with the output port 104, and the acquisition module 105 being connected with the control module 102 and the output port 104 respectively, wherein:
[0026] The acquisition module 105 is used for collecting voltage information of an external load 200 through the acquisition module 105 and sending the voltage information to the control module 102 in the case that the output port is connected with the external load.
[0027] The control module 102 is further used for determining output voltage of the programmable power supply 101 output to the conversion module 103 according to the voltage information and preset comparison information.
[0028] The conversion module 103 is used for converting the output voltage into working voltage required by the external load 200 for normal working.
[0029] Exemplarily, the output port A is connected to the external load B, and the acquisition module 105 acquires the voltage information of the external load B through the output port A and transmits the voltage information of the external load B to the control module 102. The control module 102 determines the voltage required by the external load B in the preset comparison information based on the voltage information and the preset comparison information, so as to control the programmable power supply 101 to output the voltage required by the external load B (i.e., the output voltage) to the conversion module 103.
[0030] That is, the acquisition module 105 determines the actual condition of the external load 200, i.e., the voltage information required by the external load 200. When the voltage information required by the external load 200 is determined, the control module 102 determines the specific voltage required by the external load 200 based on the voltage information and preset comparison information. The programmable power supply 101 and the conversion module 103 cooperate with each other to adjust the output voltage of the programmable power supply 101 to a voltage that can provide normal operation of the external load 200.
[0031] In some embodiments, after determining the actual conditions of the external load 200, that is, the voltage information required by the external load 200, the acquisition module 105 sends a control signal containing the voltage information required by the external load 200 to the programmable power supply 101. The programmable power supply 101 then outputs a corresponding voltage value to the conversion module 103 based on the control signal. In other words, through the coordination among the acquisition module 105, the programmable power supply 101, and the conversion module 103, the external load 200 is provided with the operating voltage required for its normal operation.
[0032] It is understandable that the output current of the programmable power supply 101 is relatively complex. If the output end of the programmable power supply 101 is connected to the input end of the external load B, that is, the programmable power supply 101 directly provides the output voltage to the external load B, in this case, since the output current of the programmable power supply 101 is relatively complex, it may cause damage to the internal electronic components of the external load B or cause the internal electronic components to be in an unstable state.
[0033] Therefore, the output voltage of the programmable power supply 101 is converted by the conversion module 103 to reduce the influence of the output voltage of the programmable power supply 101 on the internal electronic components of the external load B.
[0034] In an embodiment of the present application, the programmable power supply 101 may be a switching power supply. In some embodiments, the programmable power supply 101 is connected to the control module 102 via a serial communication protocol. For example, the programmable power supply 101 and the control module 102 exchange information via 485 communication.
[0035] The control module 102 determines the voltage information of the external load 200 currently connected to the output port 104 through the acquisition module 105 to determine the operating voltage required by the external load 200. The control module 102 sends a control signal to the programmable power supply 101 via 485 communication to adjust the output voltage of the programmable power supply 101 to the voltage required by the external load 200. The programmable power supply 101 adjusts the specific value of the output voltage under the control of the control signal sent by the control module 102 via 485 communication.
[0036] In the embodiment of the present application, the control module 102 may be a controller, which may include a control chip such as a CPU or an MCU.
[0037] In the embodiment of the present application, the conversion module 103 may be a circuit module having a voltage conversion function.
[0038] In a specific embodiment, see Figure 3 , Figure 3 FIG. 1 shows a schematic diagram of the structure of another controller provided in an embodiment of the present application. Figure 3 As shown, the conversion module 103 includes a converter 1031 and a driving unit 1032. The input end of the converter 1031 is connected to the programmable power supply 101, and the output end of the converter 1031 is connected to the input end of the driving unit 1032.
[0039] The converter 1031 is used to convert the output voltage into an operating voltage required for the external load 200 to operate normally.
[0040] The driving unit 1032 is used to drive the external load 200 to start working according to the working voltage.
[0041] In an embodiment of the present application, the converter 1031 may be a DC / DC analog circuit that is used to adjust the output voltage of the programmable power supply 101 to an operating voltage required for normal operation of an external load.
[0042] For example, the output voltage provided by the programmable power supply 101 to the converter 1031 is 24V, and the converter 1031 converts the 24V output voltage into a lower operating voltage, such as 12V or 5V.
[0043] It is worth noting that the present application does not limit the specific components of the DC / DC analog circuit, and the specific components of the DC / DC analog circuit can be flexibly set according to actual conditions.
[0044] In the examples of this application, please refer to Figure 4 , Figure 4 FIG1 shows a circuit structure diagram of a driving unit provided in an embodiment of the present application. Figure 4 As shown, the driving unit 1032 includes a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, a capacitor C and a transistor Q, wherein:
[0045] One end of the first resistor R1 is connected to the output end of the converter 1031, and the other end of the first resistor R1 is connected to one end of the second resistor R2 and the first end of the transistor Q respectively; the other end of the first resistor R1 is also used to connect to the external load 200;
[0046] The other end of the second resistor R2 is connected to one end of the third resistor R3 and one end of the capacitor C respectively; the other end of the third resistor R3 and the other end of the capacitor C are grounded;
[0047] The second end of the transistor Q is used to receive the pulse signal. The third end of the transistor Q is connected to one end of the fourth resistor R4. The other end of the fourth resistor R4 is used to be grounded.
[0048] After the converter 1031 adjusts the output voltage of the programmable power supply 101 to the operating voltage required for the normal operation of the external load, the adjusted operating voltage required for the normal operation of the external load is provided to one end of the first resistor R1 to provide the operating voltage to the driving unit 1032, so that the driving unit 1032 drives the external load 200 to start working according to the operating voltage under the action of the adjusted operating voltage required for the normal operation of the external load 200.
[0049] Through the cooperation between the converter 1031 and the driving unit 1032, the output voltage of the programmable power supply 101 is prevented from being directly provided to the external load 200, thereby preventing the internal electronic components of the external load B from being damaged or being in an unstable state due to the complex output current of the programmable power supply 101.
[0050] In the embodiment of the present application, the output port 104 is a port for connecting to an external load 200. It is understood that the present application may include multiple output ports 104. When there are multiple output ports 104, each output port 104 corresponds to a conversion module 103. In other words, multiple conversion modules 103 are connected to multiple output ports 104 in a one-to-one correspondence. It is understood that the present application does not impose any restrictions on the specific number of output ports 104, and the specific number of output ports 104 can be flexibly adjusted according to actual circumstances.
[0051] In some embodiments, the controller 100 further comprises an internal module, an input end of the internal module being connected with an output end of the programmable power supply 101, and an output end of the internal module being connected with an input end of the conversion module 103, the internal module being used for voltage stabilization and the like on the output voltage of the programmable power supply 101, so as to reduce the complexity of the current output by the programmable power supply 101, and to reduce the influence on the devices in the external load 200. In a specific embodiment, the internal module can comprise a rectifier filter circuit and an operational amplifier circuit.
[0052] Due to the plurality of output ports 104, the external loads 200 with different working voltages can be connected with the controller 100 through different output ports 104. The controller 100 controls the programmable power supply 101 to provide corresponding voltages to the conversion module 103 corresponding to the output port 104 corresponding to each external load 200 through the voltage information of each external load 200 collected by the collection module 105, and then converts through the conversion module 103, so that each external load 200 obtains a suitable working voltage.
[0053] Specifically, in some embodiments, the collection module 105 is used to obtain the resistance information sent by the external load 200, and send the resistance information to the control module 102.
[0054] The control module 102 is used to determine the voltage information according to the resistance information.
[0055] When the output port 104 is connected with the external load 200, the external load 200 sends the resistance information of the external load 200 to the collection module 105, so that the collection module 105 sends the resistance information of the external load 200 to the control module 102, and the control module 102 determines the working voltage corresponding to the resistance information of the external load 200 according to the resistance information and the preset reference information.
[0056] The preset reference information is a preset reference table, and the preset reference information comprises working voltages corresponding to different resistance information. In the case of knowing the resistance information of the external load 200, the working voltage corresponding to the resistance information of the external load 200 can be obtained by querying the preset reference information, so as to realize the control module 102 determining the voltage information of the external load 200 according to the resistance information.
[0057] In some embodiments, the collection module 105 is used to determine the resistance information by collecting the resistance value of the identification resistance on the input end of the external load 200.
[0058] The external load 200 is provided with an identification resistance on the wiring head connected with the output port 104. When the output port 104 is connected with the external load 200, the identification resistance will present a corresponding value according to the working voltage of the external load 200.
[0059] The AD sampling port of the single chip microcomputer set in the controller 100 can be used to collect data. The acquisition module 105 includes an AD sampling port, which collects the resistance value of the identification resistor corresponding to the external load 200 to determine the resistance information, and then determines the voltage information of the external load 200 based on the resistance information.
[0060] See also Figure 5 , Figure 5 FIG. 1 shows a schematic diagram of the structure of a detection system provided in an embodiment of the present application. Figure 5 As shown, the detection system 300 includes: an external load 200 and the controller 100, specifically:
[0061] In some embodiments, the external load 200 may be a light source device. For example, a light source device that can emit fixed brightness. It is understood that this application does not limit the specific type of the external load 200.
[0062] An identification resistor is provided on the terminal connecting the external load 200 to the output port 104. When the output port is connected to the external load 200, the identification resistor will take on a corresponding value according to the operating voltage of the external load 200.
[0063] This allows the AD sampling port of the single-chip microcomputer set in the controller 100 to collect the specific numerical value of the identification resistor, and determine the voltage corresponding to the specific numerical value of the identification resistor based on the preset reference information. The control module then further controls the output voltage of the conversion module corresponding to the output port corresponding to the external load 200 to the programmable power supply according to the determined voltage condition.
[0064] Those skilled in the art will clearly understand that, for the convenience and brevity of description, the specific working processes of the external load 200 and the controller 100 described above may refer to the corresponding processes in the aforementioned method embodiments, which will not be repeated here.
[0065] An embodiment of the present application provides a controller and detection system, comprising: a programmable power supply, a control module, a conversion module, an output port, and an acquisition module. The programmable power supply is connected to the control module and the conversion module, the conversion module is connected to the output port, and the acquisition module is connected to the control module and the output port, respectively. The acquisition module is configured to collect voltage information of an external load when the output port is connected and transmit it to the control module. The control module is further configured to determine the output voltage of the programmable power supply to the conversion module based on the voltage information and preset comparison information. The conversion module is configured to convert the output voltage into the operating voltage required for the normal operation of the external load. Thus, the actual external load condition is determined by the acquisition module, and the output voltage of the programmable power supply is adjusted by the conversion module to ensure that the output voltage of the programmable power supply is sufficient for the normal operation of the external load.
[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
