[0021] The preferred embodiments of the utility model are described below in combination with the drawings, and it should be understood that the preferred embodiments described herein are only used for illustrating and explaining the utility model, and are not used for limiting the utility model.

[0022] The following description refers to the accompanying drawings, wherein the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims. In the description of the present application, it should be understood that the terms "first", "second", "third", etc. are only used to distinguish similar objects, and do not have to be used to describe a specific order or sequence, nor can they be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0023] Referring toFigures 1-5 The utility model discloses a non - access type equipment state monitoring device, including control module 1, acquisition module 2 and feedback module 3, control module 1 is connected with acquisition module 2, feedback module 3, acquisition module 2 is connected with the equipment 4 of monitoring, acquisition module 2 includes two photosensitive units 201, two photosensitive units 201 are connected with the equipment 4 of monitoring, control module 1.

[0024] Wherein, photosensitive unit 201 is photosensitive resistance, and the connection of photosensitive unit 201 and the equipment to be detected is specifically that photosensitive unit 201 is arranged at the status indicator lamp of the equipment 4 to be monitored, so that the light source of the status indicator lamp can be identified by photosensitive unit 201 when the status indicator lamp is bright.

[0025] Referring to Figure 2 As shown in the figure, the main control chip 101 is a single-chip microcomputer of model STC8H, and the main control chip 101 aims at super strong anti-interference, ultra-low price, high speed, low power consumption. Under the same working frequency, the single-chip microcomputer of model STC8H is about 12 times faster than the single-chip microcomputer of traditional model 8051. The single-chip microcomputer of model STC8H is a single clock / machine cycle (1T) single-chip microcomputer produced by STC, which is a new generation of 8051 single-chip microcomputer with wide voltage, high speed, high reliability, low power consumption, strong anti-static and strong anti-interference, and super encryption.

[0026] In the control module 1, the RXD and TXD pins are reserved to realize serial communication (reserved for later expansion of functions), and the button KEY1 is connected, so that man-machine exchange operation can be realized.

[0027] Referring to Figure 3 As shown in the figure, the photosensitive unit 201 can adopt photosensitive resistance of model 5516, which corresponds to resistors R2 and R4 in Figure 3 The brightness of the indicator light of the equipment 4 to be monitored is collected through the photosensitive resistors R2 and R4. When the resistance values of the photosensitive resistors R2 and R4 change, the voltage output by the collection ends CHANNEL0 and CHANNEL1 will change with the resistance values of the photosensitive resistors. Then, the main control chip 101 of the control module 1 is used to judge the voltage of the two channels to obtain the state of the status light of the equipment 4 to be monitored.

[0028] According to the needs of the scene, we set that the main control chip 101 outputs an alarm signal when it detects that the two collection channels are out of synchronization for more than 100 ms or more. The alarm signal is specifically sent by the buzzer of the warning unit 301 and displayed by the man-machine interaction unit 302. The preset time of 100 ms can be modified according to the needs of the scene.

[0029] The following is an example of an actual case in the field:

[0030] Traditional equipment state monitoring can only determine the equipment state by opening the equipment on site, observing whether the internal state indicator light is emitting, so when the equipment fails, it can only be checked after the train exits service; and it may also appear that when the personnel check, the fault has disappeared (the state indicator light has changed), so it cannot directly lock the cause, unless the fault phenomenon has always existed (the state indicator light does not change), thus causing great difficulty for subsequent processing, and it is more passive.

[0031] Suppose that the equipment to be monitored 4 has two power modules of A and B channels, and the photosensitive unit 201 is arranged beside the state indicator lights of A and B channels.

[0032] After the train cab is activated, the two power modules of A and B channels will always work, and the state indicator lights will be always on, if any of the power modules has input or output abnormality, the state indicator light on the panel will have a slight change, for example, flashing, which will cause the system to fail and shut down.

[0033] The utility model utilizes the characteristics of the photosensitive resistance, simultaneously collects the state indicator lights on the power modules of A and B channels, converts the light source into a voltage signal and inputs it to the main control chip 101 in the control module 1, the main control chip 101 converts the analog signal into a digital signal, and simultaneously defines that the simultaneous extinguishing of A and B channels is the cab not activated and the simultaneous lighting is the cab activated according to the working principle of the equipment.

[0034] When the state indicator lights of A and B channels have different display for 100 ms and above, it is defined as a fault, and the channel with abnormality is given, and according to the clock of the control module 1, the fault information is stored with Beijing time as the symbol.

[0035] Meanwhile, when the main control chip 101 detects that there is a fault, the fault information is output to the feedback module 3, the sound alarm prompt is given through the warning unit 301, and the specific fault information is displayed through the liquid crystal display screen of the man-machine interaction unit 302; after the personnel arrive on site, the alarm record and fault information can be observed through the man-machine interaction unit 302, so as to simply and quickly lock the fault point, replace the fault element of the equipment to eliminate hidden dangers.
