All other embodiments that can be obtained by a person skilled in the art without inventive step based on the embodiments in this application are within the scope of protection of this application.

Some embodiments of the application are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Fig. 1 is a schematic view of a three-color lamp monitoring apparatus according to an embodiment of the present disclosure, and as shown in fig. 1, the three-color lamp monitoring apparatus 100 at least includes the following components: the light collecting unit 110, the photosensitive unit 120, the judging unit 130, and the communication unit 140. The light collection unit 110, the light sensing unit 120, the judgment unit 130 and the communication unit 140 are electrically connected in sequence.

Referring to fig. 2 and fig. 3, in an embodiment of the present invention, the three-color lamp monitoring apparatus 100 is disposed on a machine 200. The machine 200 is provided with a three-color lamp 210. The light collection unit 110 includes a first photosensor 111, a second photosensor 112, a third photosensor 113, a first light path 114, a second light path 115, a third light path 116, and a bracket 150 (see fig. 3). In the embodiment of the present application, the three-color lamp 210 includes a red lamp 211, a yellow lamp 212, and a green lamp 213. The first photosensor 111 is connected to the red light 211 via a first light path 114, the second photosensor 112 is connected to the yellow light 212 via a second light path 115, and the third photosensor 113 is connected to the green light 213 via a third light path 116. The first photosensor 111, the second photosensor 112, and the third photosensor 113 are used to collect light from the red light 211, the yellow light 212, or the green light 213, respectively.

The light collection unit 110 collects light through the first light path 114, the second light path 115, and the third light path 116, and transmits the collected light to the light sensing unit 120. The first, second and third

optical paths

114, 115, 116 may be optical fibers, mirrors, etc. any device capable of transmitting light. For example, in one embodiment, the first light path 114, the second light path 115 and the third light path 116 may be optical fiber light inlets. One end of the optical fiber light inlet tube can be adsorbed on the three-color lamp through a sucking disc and the like, so that the light inlet of the light collection unit 110 is aligned with the light source.

A light shielding member may be disposed outside the first light path 114, the second light path 115, and the third light path 116. The light shielding assembly is used to prevent external light from mixing into the light collected by the light collecting unit 110. The shade assembly may be made of a material capable of shading light.

The photosensitive unit 120 is used for sensing voltage changes in the first photosensitive sensor 111, the second photosensitive sensor 112 and the third photosensitive sensor 113. The first photosensor 111, the second photosensor 112 and the third photosensor 113 are provided with photo resistors therein. When the light from the three-color lamp 210 irradiates the photo resistor, the resistance of the photo resistor changes, causing the voltage across the photo resistor to change. In this way, the light sensing unit 120 can transmit the current generated by the voltage variation to the determining unit 130. It will be appreciated that the first photosensor 111 converts the detected intensity of light from the red light 211 into a first light-sensitive signal. The second photosensor 112 converts the detected light intensity from the yellow light 212 into a second light-sensitive signal. The third photosensor 113 converts the detected light intensity from the green light 213 into a third light-sensitive signal.

The determining unit 130 is configured to determine the state of the three-color lamp 210 according to the light intensity corresponding to the current monitored by the light sensing unit 120. The determining unit 130 includes a first determining subunit 131, a second determining subunit 132, and a third determining subunit 133. Logic circuits are disposed in the first determining subunit 131, the second determining subunit 132, and the third determining subunit 133. The first determining subunit 131 is configured to determine whether the first photosensitive signal is in a light-on state, that is, the first determining subunit 131 is configured to determine whether the red light 211 is in a light-on state. The second determining subunit 132 is configured to determine whether the second photosensitive signal is in a light-on state, that is, the second determining subunit 133 is configured to determine whether the yellow light 212 is in a light-on state. The third determining subunit 133 is configured to determine whether the first photosensitive signal is in a lighting state, that is, the third determining subunit 133 is configured to determine whether the green light 213 is in a lighting state. Specifically, the logic circuit determines the illumination intensity of the three-color lamp 210 according to the voltage values of the first photosensitive signal, the second photosensitive signal and the third photosensitive signal, and outputs the lighting states of the red lamp 211, the yellow lamp 212 and the green lamp 213 respectively. For example, if the illumination intensity of the tri-color lamp 210 is higher than the illumination intensity preset in the determination unit 130, the determination unit 130 determines that the tri-color lamp 210 is in a lighting state, and outputs corresponding state information, that is, outputs the corresponding lamp state as lighting. If the illumination intensity of the three-color lamp 210 of the machine tool is lower than the illumination intensity preset in the determination unit 130, the determination unit 130 determines that the three-color lamp 210 is in a light-off state, and outputs corresponding state information, that is, outputs that the corresponding lamp state is a non-light-on lamp.

The communication unit 140 is configured to transmit the status information of the tri-color lamp 210 generated by the determining unit 130 to the gateway 300. If the light sensing unit 120 detects that the state of the tri-color light 210 changes, the communication unit 140 immediately sends the state information of the tri-color light to the gateway 300. The Communication unit 140 may be any Communication unit capable of establishing Communication with the gateway 300, such as a Bluetooth (Bluetooth) unit, a Near Field Communication (NFC) unit, and the like, and is not particularly limited herein. If the light sensing unit 120 does not detect that the state of the tri-color lamp 210 changes, the state information of the tri-color lamp is periodically sent to the gateway 300 through the communication unit 140. For example, if the state of the three-color machine tool lamp 210 is not changed, the determining unit 130 sends the state information of the three-color machine tool lamp 210 to the gateway 300 through the communication unit 140 every hour.

Referring to fig. 3 again, in an embodiment of the present application, the three-color lamp monitoring apparatus 100 further includes a bracket 150. The bracket 150 is disposed on a three-color lamp post of the machine 200. The bracket 150 is adjustable up and down for securing the tri-color light monitoring apparatus 100 to the tri-color light pole. In some embodiments, the bracket 150 is further used to align the light collection unit 110 with the three-color lamp 210, so that the light collection unit 110 can collect the light variation of the three-color lamp 210.

In an embodiment of the present application, the three-color lamp monitoring apparatus 100 further includes a maintenance unit 160, and the maintenance unit 160 is connected to the determination unit 130. The maintenance unit 160 is configured to monitor whether a plurality of lamps in the three-color lamp 210 are simultaneously turned on in the status information detected by the three-color lamp monitoring apparatus 100. Since only one of the three lamps of the three-color lamp is normally in the on state at the same time. Therefore, when the three-color lamp monitoring apparatus 100 detects that at least two lamps (for example, two or three lamps) are simultaneously turned on, it may be determined that the state information of the three-color lamp 210 acquired by the determination unit 130 is wrong. In this way, the illumination intensity preset in the determination unit 130 can be adjusted according to the information monitored by the maintenance unit 160, so that the determination unit 130 can output correct status information of the tri-color lamp 210.

Of course, in other embodiments of the present application, the illumination intensity preset in the determining unit 130 may also be adjusted according to the instruction sent by the gateway 300 to the communication unit 140, so as to improve the accuracy of the determination result of the determining unit 130.

Fig. 4 is a block diagram of a three-color lamp monitoring system 10 according to an embodiment of the present application. As shown in fig. 4, the three-color lamp monitoring system 10 includes at least the following: the three-color lamp monitoring device 100, the gateway 300 and the server 400. The three-color lamp monitoring device 100 is communicatively connected to a gateway 300, and the gateway 300 is communicatively connected to the server 400.

In an embodiment of the present application, the function and principle of the three-color lamp monitoring device 100 are the same as or similar to those of the three-color lamp monitoring device 100 in fig. 1, and are not described herein again.

In one embodiment of the present application, the gateway 300 includes a local area network module 320, a data caching module 310, and an internet module 330. The gateway 300 is communicatively connected to the three-color lamp monitoring apparatus 100 through the lan module 320. The gateway 300 is communicatively connected to the server 400 through the internet module 330. The lan module 320 may be a Bluetooth (Bluetooth) module, a Near Field Communication (NFC) module, or the like capable of forming a lan. The internet module 330 includes a wired communication module. Optionally, the internet module 330 further includes a wireless communication module. The wired communication module of the internet module 330 may be an ethernet module, etc. Optionally, the ethernet module is an optical interface, an electrical interface, or a combination thereof. The Wireless communication module of the internet module 330 is a Wireless Local Area Network (WLAN) interface, a cellular network communication interface, or a combination thereof. The operating system applied by the gateway 300 may be LINUX, UNIX, WINDOWS, etc., and is not limited in particular.

In an embodiment of the present application, the data caching module 310 is configured to store state information of the tri-color lamp reported to the gateway 300 by the tri-color lamp monitoring apparatus 100. The caching module 310 has a timed deletion mechanism and a threshold deletion mechanism. The timing deleting mechanism is that the three-color lamp state information is deleted after the three-color lamp state information is stored for a certain time. For example, when the time for storing a piece of three-color light state information in the cache module exceeds one day, the piece of three-color light state information is cleared. The threshold deletion mechanism is to delete a certain amount of the three-color light status information when the three-color light status information stored in the cache module 310 exceeds a threshold. For example, when the three-color lamp status information stored in the cache module 310 exceeds 50MB, the oldest 100 pieces of three-color lamp status information are deleted.

In an embodiment of the present application, the gateway 300 provides a World Wide Web (Web) service to upload status information of the tri-color lamps of the machine tool and the like to the server 400. In one possible embodiment, the gateway 300 further provides an Application Programming Interface (API) to implement network configuration and configure the network-connected three-color lamp monitoring apparatus 100.

In an embodiment of the present application, when the gateway 300 is provided with an API service, the mobile terminal may connect to the gateway 300 to connect the new three-color lamp monitoring apparatus 100 to the local area network established by the gateway 300. For example, when the mobile terminal is connected to a local area network established by the gateway 300, the mobile terminal may monitor broadcast information in the local area network to obtain a gateway list. The mobile terminal can select the gateway 300 and the three-color lamp monitoring device 100 to be matched, and update the information of the three-color lamp monitoring device 100 to the gateway 300.

In an embodiment of the present application, the gateway 300 may add a server link through a WEB service, and connect to the server 400 according to the server link. In this way, the gateway 300 may transmit the status information of the tri-color lights cached in the gateway 300 to the server 400 through a server link.

In an embodiment of the present application, the server 400 is configured to receive status information of the three-color lamp from the gateway 300. The server 400 includes a storage module for storing the three-color lamp status information and the configuration information of the three-color lamp monitoring device 100.

In an embodiment of the present application, the interactive communication between the server 400 and the gateway 300 may be implemented by using a Message Queue Telemetry Transport (MQTT). It should be noted that the interactive communication between the server and the processing device may also be implemented by other communication protocols, for example, a Transmission Control Protocol (TCP), and the application does not limit the specific communication Protocol.

In an embodiment of the present application, the server 400 may further obtain the latest status of the three-color light monitoring apparatus 100. For example, the server 400 sends a device status update command to the gateway 300, and the gateway 300 sends the received command to the corresponding three-color lamp monitoring device 100. After receiving the instruction, the three-color lamp monitoring device 100 immediately uploads the state information of the three-color lamp to the gateway 300. The gateway 300 then transmits the instant tri-color light status information uploaded by the tri-color light monitoring apparatus 100 to the server 400. The server 400 stores the received instant three-color lamp status information in a storage module.

In an embodiment of the present application, the server 400 may be further configured to update the preset light intensity value of the determining unit 130 in the three-color light monitoring apparatus 100. For example, the server 400 sends the updated light intensity value to the gateway 300, so as to send the updated light intensity value to the three-color lamp monitoring apparatus 100 through the gateway 300. The three-color lamp monitoring device 100 updates the preset light intensity value of the determination unit 130 according to the updated light intensity value. After the preset light intensity value is modified, the determining unit 130 in the three-color lamp monitoring device 100 generates configuration information of the three-color lamp monitoring device 100. The three-color light monitoring device 100 sends the configuration information to the gateway 300, and the gateway 300 sends the configuration information to the server 400. The server 400 stores the configuration information in the storage module for subsequent invocation or update.

It should be understood by those skilled in the art that the above embodiments are only for illustrating the present application and are not used as limitations of the present application, and that suitable modifications and changes of the above embodiments are within the scope of the claims of the present application as long as they are within the spirit and scope of the present application.
