the voltage conversion module 203 is electrically connected to the photoelectric conversion module 201, and performs voltage conversion on the power supply voltage of the state monitoring device to provide a working voltage for the photoelectric conversion module 201.
It should be noted that the photoelectric conversion module 201 is any conventional circuit type capable of performing photoelectric conversion, and this example does not limit the specific circuit type, but only requires that the photosensitive element 2011 is aligned with the light-passing hole 104. The signal transmission module 202 is any circuit capable of implementing signal transmission, and the present example does not limit the specific circuit form. In one embodiment, the signal transmission module 202 is an I/O module. The voltage conversion module 203 is any one of the existing circuit forms that can implement voltage conversion, and this example does not limit the specific circuit form thereof.
As an example, as shown in fig. 1, the light shield case 100 includes: the optical module comprises a lower shell 101 and an upper shell 102 fastened on the lower shell, wherein at least one signal transmission module lead port 103 is arranged on the side surface of the lower shell 101 corresponding to the signal transmission module 202, and the light through hole 104 is arranged on the upper surface of the upper shell 102. In this example, the light shielding case 100 has a rectangular structure, in which the lower case 101 is composed of a bottom surface and four side surfaces surrounding the bottom surface, and the upper case 102 is composed of a top surface; in order to achieve good light-shielding performance, the four surfaces of the light-shielding housing 100 in this example are made of black light-shielding acrylic. The number of the light through holes 104 is the same as the number of the signal transmission module lead ports 103, and the arrangement mode is the same; in this example, the light passing hole 104 is in arrange along its length direction equidistance in proper order on the top surface of shading casing 100, signal transmission module pin hole 103 is in also arrange along its length direction equidistance in proper order on the side of shading casing 100, simultaneously with signal transmission module 202 one-to-one to expose the pin end of signal transmission module 202 will the signal of signal transmission module 202 is drawn forth shading casing 100.
Specifically, the light shielding housing 100 further includes: at least one latch (not shown), said latch comprising: the locking piece is matched with the clamping piece; the locking piece is arranged on the upper surface of the upper shell, and the locking piece is arranged on the side surface of the lower shell. In this example, the locking member is sleeved in the locking member and locked, so that the upper housing 102 and the lower housing 101 can be locked. Of course, other existing structures capable of achieving locking are also applicable to the present example, and the present example is only an example description, and does not limit the specific structure of the locking portion.
Specifically, as shown in fig. 1, the light shielding housing 100 further includes: at least one upper and lower support column 105 disposed within the light shielding housing 100; the upper and lower support columns 105 are fixed to the inner surface of the upper casing 102 and/or the inner surface of the lower casing 101, and are used for supporting the upper casing 102 and the lower casing 101.
As an example, as shown in fig. 1, the status monitoring component 200 further includes: the direct-plug interfaces 204 and the photoelectric conversion modules 201 are in one-to-one correspondence and are arranged below the corresponding light through holes 104, and are electrically connected to the corresponding signal transmission modules 202, so that the photoelectric conversion modules 201 are installed on the direct-plug interfaces 204 in a plug-in manner, and the photoelectric conversion modules 201 are electrically connected to the corresponding signal transmission modules 202. Through the design of the direct-insertion interface 204, the detachable electrical connection of the photoelectric conversion module 201 is realized, which is not only beneficial to the replacement and maintenance of the photoelectric conversion module 201, but also beneficial to the increase or decrease of the number of the photoelectric conversion modules 201 in different monitoring scenes (mainly when the photoelectric conversion modules have different numbers of light source indication signals), thereby greatly improving the application flexibility of the state monitoring device 10 in the present example. It should be noted that, in practical applications, in order to increase the reusability of the state monitoring apparatus 10 in this example, the state monitoring component 20 may include a plurality of corresponding add-drop interfaces 204 and signal transmission modules 202, and according to a specific application scenario, the state monitoring of the device is implemented by installing a certain number of photoelectric conversion modules 201 on the add-drop interfaces 204; when the number of devices in a specific application scene changes, the number can be increased or decreased by increasing or decreasing the corresponding photoelectric conversion module 201.

Wherein, the state judgment mode is as follows: the device corresponding to the signal transmission module with the electric signal output is in a working state (the state can be defined according to the corresponding actual situation when the lamp is turned on in specific application and is not limited to the working state), and the device corresponding to the signal transmission module without the electric signal output is in a non-working state (the state can be defined according to the corresponding actual situation when the lamp is turned off in specific application and is not limited to the non-working state). Although the light-shielding housing 100 is adopted in the present example to avoid the influence of the external ambient light on the test result, since the external ambient light is always present, it may cause that all signal transmission modules have electrical signal output, and thus accurate monitoring cannot be achieved; to avoid this, the state determination method can be adjusted as follows: after reading all the signal transmission modules, the processing component compares each read data with a set threshold in sequence, determines that the device corresponding to the signal transmission module is in a working state when the read data is greater than or equal to the set threshold (the state can be defined according to the actual situation corresponding to the lighting in the specific application and is not limited to the working state), and determines that the device corresponding to the signal transmission module is in a non-working state when the read data is less than the set threshold (the state can be defined according to the actual situation corresponding to the lighting-off in the specific application and is not limited to the non-working state). It should be noted that the data reading and the above state judgment performed by the processing element are well known to those skilled in the art, and therefore, are not described herein again.
As an example, the condition monitoring component 200 further comprises: a power supply signal introducing module (not shown in the figure) electrically connected between the processing module and the voltage conversion module 203, and the processing module further provides a power supply voltage to the state monitoring apparatus 10 through the power supply signal introducing module. In one embodiment, the power supply signal introducing module is an I/O module. When the state monitoring device 200 further includes a power supply signal introducing module, a power supply signal introducing module pin port (not shown) is further disposed on a side surface of the lower case 101 corresponding to the power supply signal introducing module to expose a pin terminal of the power supply signal introducing module, so as to provide a power supply voltage to the state monitoring apparatus 10. It should be noted that the power supply signal introducing module is any one of the existing circuit forms capable of implementing voltage signal transmission, and this example does not limit the specific circuit form thereof.
Specifically, the processing module provides a 24V dc supply voltage to the status monitoring device 10 through the power supply signal introducing module, and the voltage conversion module 203 converts the 24V dc supply voltage into a 5V dc working voltage and outputs the voltage to the photoelectric conversion module 201.

As an example, the state monitoring device 10 is mounted on the stack-type solenoid valve 20 by an adhesive layer, and the state indicator lamps 211 in the stack-type solenoid valve 20 are aligned with the light passing holes 104 in the state monitoring device 10 one by one. In this example, the adhesive layer is a double-sided adhesive tape.

It should be noted that the control signal is generated by a superior controller according to the actual application requirement, and the control unit 22 controls the on and off of each electromagnetic valve 21 according to the control signal is well known to those skilled in the art, so that the detailed description is omitted here.
Referring to fig. 1 and 2, the operation of the condition monitoring system of the stacked solenoid valve will be described in detail.
Before monitoring the state of the stacked electromagnetic valves, installing the same number of the photoelectric conversion modules 201 on the direct-insert interfaces 204 at corresponding positions according to the number of the actually monitored electromagnetic valves, and locking the light shielding shell 100 through the locking parts; the condition monitoring device 10 is then mounted on the stacked solenoid valves 20 such that the light passing holes 104 in the condition monitoring device 10 and the condition indicating lamps 211 in the stacked solenoid valves 20 are aligned one by one.
When one or more solenoid valves 21 in the stacked solenoid valves 20 are turned on, the corresponding status indicator lamps are turned on, and at this time, the corresponding photoelectric conversion modules 201 collect optical signals of the turned-on status indicator lamps 21 through the light-through holes 104 and convert the optical signals into electric signals to be output through the corresponding signal transmission modules; and the processing component judges that the corresponding electromagnetic valve is in a conducting state and other electromagnetic valves are in a closing state according to the output electric signal.
