When the ac power source 107 supplies power to the switching power source 104, the switching power source 104 may convert the voltage (e.g., 220V) of the ac power source 107 into an operating voltage required by the wireless bridge 106 to enable the wireless bridge 106 to operate normally after being powered on, and the operating voltage may be a dc voltage (e.g., 24V). The ac power source 107 may directly power the fiber monitoring module 102. When the optical fiber 108 to be detected is detected, the input end of the light attenuation detection probe 101 is connected with the optical fiber 108 to be detected, and the light attenuation detection probe 101 can detect the light attenuation value of the optical fiber 108 to be detected. Specifically, the connection position of the optical attenuation detection probe 101 and the optical fiber 108 to be detected can be set according to the specific requirements of the user, that is, the connection position can be set at any position of the optical fiber 108 to be detected, for example, the connection position can be a position near the upper computer to which the optical fiber 108 to be detected is connected, or a position near the external switch to which the optical fiber 108 to be detected is connected. Then, the output end of the light attenuation detection probe 101 is connected with the input end of the optical fiber monitoring module 102, so that the optical fiber monitoring module 102 can obtain the light attenuation value detected by the light attenuation detection probe 101 in real time, and judge whether the optical fiber 108 to be detected is normal or not according to the light attenuation value.

If the light attenuation value is continuously greater than the preset light attenuation threshold value within a preset time (for example, 2min), it indicates that the data transmission function of the optical fiber 108 to be detected is abnormal, and the normally open switch 103 is controlled to be closed. After the normally open switch 103 is closed, the power end of the relay 105 is connected with the alternating current power supply 107, namely, the alternating current power supply 107 starts to supply power to the relay 105, due to electromagnetic induction, after the coil of the relay 105 is electrified, the normally open contact in the relay 105 can be attracted, the output end of the switch power supply 104 is connected with the power end of the wireless bridge 106, so that the switch power supply 104 can realize power supply to the wireless bridge 106, and the wireless bridge 106 can transmit data transmitted by the optical fiber 108 to be detected through a wireless network. According to the method and the device, when the optical fiber 108 to be detected is detected to be abnormal (namely, the light attenuation value is greater than the light attenuation threshold value), the switch power supply 104 is controlled to supply power to the wireless bridge 106, so that the wireless bridge 106 can transmit target data which are originally required to be transmitted through the optical fiber 108 to be detected through a wireless network, and the reliability of data transmission is ensured.

For example, the optical fiber monitoring module 102 may be composed of an optical fiber detector 1021 and a controller 1022, and when monitoring the optical fiber 108 to be detected, the optical fiber detector 1021 acquires a light attenuation value collected by the light attenuation detection probe 101, and sends the acquired light attenuation value to the controller 1022 for processing, for example, the light attenuation value collected by the light attenuation detection probe 101 may be an analog signal, and the optical fiber detector 1021 may perform analog-to-digital conversion on the received light attenuation value to obtain a light attenuation value in a digital signal format that can be processed by the controller 1022. After receiving the light attenuation value, the controller 1022 may compare the obtained light attenuation value with a preset light attenuation threshold (e.g., 25dB), and if the obtained light attenuation value is smaller than the preset light attenuation threshold, it indicates that the data transmission function of the optical fiber 108 to be detected is normal, so that the normally open switch 103 is kept in an open state, that is, the normally open switch 103 is not controlled to be closed. If the obtained light attenuation value is larger than the preset light attenuation threshold value, it indicates that the transmission function of the optical fiber 108 to be tested at the moment is abnormal.

The automation control system 200 further includes: the first optical fiber monitoring device 204 connected to the master switch 203, the second optical fiber monitoring device 205 connected to each slave host computer 202, the first optical fiber monitoring device 204, and the second optical fiber monitoring device 205 are all the optical fiber monitoring devices provided in the first aspect of the embodiments of the present disclosure.

The input ends of the optical attenuation detection probes 101 of the first optical fiber monitoring device 204 and the second optical fiber monitoring device 205 are connected with optical fibers.

For example, the first optical fiber monitoring device 204 and the second optical fiber monitoring device 205 detect the optical fibers through the optical attenuation detecting probe 101. When the data transmission function of the optical fiber is normal, the slave host computer 202 sends the generated data to the master switch 203 through the optical fiber, and after receiving the data sent by the slave host computer 202, the master switch 203 sends the data to the master host computer 201 through the network cable, so that the master host computer 201 can receive the data sent by the slave host computer 202. Similarly, the master upper computer 201 sends the generated data to the master switch 203 through the network cable, and the master switch 203 sends the data to the slave upper computer 202 through the optical fiber, so that the slave upper computer 202 can receive the data sent by the master upper computer 201, and the data transmission between the master upper computer 201 and the slave upper computer 202 is realized.

The input ends of the optical attenuation detection probes 101 of the first optical fiber monitoring device 204 and the second optical fiber monitoring device 205 are connected to optical fibers. Specifically, as shown in fig. 9, the connection position between the input end of the optical attenuation detecting probe 101 of the first optical fiber monitoring apparatus 204 and the optical fiber may be a position provided near the optical fiber access main switch 203. The connection position between the input end of the optical attenuation detection probe 101 of the second optical fiber monitoring device 205 and the optical fiber may be a position near the upper computer 202 for optical fiber access. Further, when there are a plurality of slave upper computers 202, there are also a plurality of second optical fiber monitoring devices 205, and the connection position between the input end of the optical attenuation detecting probe 101 of each second optical fiber monitoring device 205 and the optical fiber may be a position where the optical fiber is connected to the vicinity of the slave upper computer 202. Accordingly, the connection position between the input end of the optical attenuation detecting probe 101 of the first optical fiber monitoring apparatus 204 and the optical fiber may be plural, and may be a position provided near each slave host 202 through the optical fiber access master switch 203, as shown in fig. 9.

Specifically, when the data transmission function of the optical fiber is abnormal, the first optical fiber monitoring device 204 and the second optical fiber monitoring device 205 both detect that the data transmission function of the optical fiber is abnormal through the optical attenuation detection probe 101, and at this time, data can only be transmitted between the master upper computer 201 and the at least one slave upper computer 202 through the wireless network. That is, the host computer 201 receives or transmits data through the wireless bridge 106 of the first optical fiber monitoring device 204, and receives or transmits data from the host computer 202 through the wireless bridge 106 of the second optical fiber monitoring device 205. For example, the master upper computer 201 generates first data, transmits the first data to the first optical fiber monitoring apparatus 204 through the master switch 203, transmits the first data through the wireless network by the wireless bridge 106 of the first optical fiber monitoring apparatus 204, receives the first data by the wireless bridge 106 of the second optical fiber monitoring apparatus 205, and transmits the first data to the slave upper computer 202. Similarly, the slave host computer 202 generates second data and sends the second data to the second optical fiber monitoring device 205, then the wireless bridge 106 of the second optical fiber monitoring device 205 sends the second data out through a wireless network, the wireless bridge 106 of the first optical fiber monitoring device 204 receives the second data, the first optical fiber monitoring device 204 sends the second data to the master switch 203, and finally the master switch 203 sends the second data to the master host computer 201.

It should be noted that the IP address and other parameters need to be preset in the wireless bridge 106 of the first optical fiber monitoring device 204 and the wireless bridge 106 of the second optical fiber monitoring device 205, so that the IP address of the wireless bridge 106 of the first optical fiber monitoring device 204 and the IP address of the wireless bridge 106 of the second optical fiber monitoring device 205 are in the same network segment, and thus data transmission can be performed between the master upper computer 201 and the at least one slave upper computer 202 through the wireless network when the data transmission function of the optical fiber is abnormal.

FIG. 10 is a schematic diagram illustrating another automated control system according to an exemplary embodiment, as shown in FIG. 10, the system 200 further comprising: UPS (English: Uninterruptible Power System, Chinese: Uninterruptible Power supply) 206.

The UPS 206 is connected with the main upper computer 201 to supply power to the main upper computer 201, and the UPS 206 is connected with the first optical fiber monitoring device 204 to supply power to the first optical fiber monitoring device 204.

For example, the master upper computer 201 is a central control computer that can directly issue a control command, and the data size is huge, if the master upper computer 201 stops working due to power failure, all the slave upper computers 202 will stop working, and even the whole system will be paralyzed in a serious case, so the UPS 206 needs to be used to supply power to the master upper computer 201, so as to ensure that the master upper computer 201 can continue to operate when the conventional power supply is interrupted. In addition, the UPS 206 may also continuously supply power to the first optical fiber monitoring device 204, so that the master host computer 201 can still transmit data when the data transmission function of the optical fiber is abnormal.
