The invention discloses a printer consumable management method and system, electronic equipment and a storage medium, and relates to the field of printer management. In the method, a first RFID of the consumable is read through an RFID reader of a printer, and the first RFID is transmitted to an application program through wireless transmission; when the application program receives the first RFID, querying a corresponding template through the first RFID and displaying the template in the application program; in response to the operation that a user clicks the target template, the target template is used for printing, the first length of each time of printing of the consumables is recorded, the multiple first lengths are added to obtain a second length, and the difference value between the total length of the consumables and the second length is calculated; when the difference value is smaller than the threshold value, it is prompted that the remaining length of the consumables is insufficient, and when the difference value is zero, the first RFID is added into the blacklist, and replacement of the consumables is prompted. By implementing the technical scheme provided by the invention, the use condition of the consumables can be monitored in real time, and the printer consumables can be effectively managed.

The utility model discloses a kind of early warning devices about preventing steel wire rope to be twisted into speed reducer, it is related to early warning device technical field, to solve the problem of steel wire rope running groove and being twisted into speed reducer to cause its damage, operation interruption. The device includes support, touch type positioner, alarm, screw rod and contactor;Support is welded on the outside of speed reducer, across speed reducer and steel wire rope reel, for fixing other components;Touch type positioner is installed on the top of support by screw rod, for signal transmission;Alarm is installed in crane cab;Contactor is installed in hoist electrical control cabinet, for controlling hoist operating circuit and triggering alarm. When working, if steel wire rope deviates from predetermined path and touches touch type positioner, positioner sends signal to contactor, contactor immediately cuts off hoist power supply to make it stop running, and triggers alarm to prompt operator to handle. The device can prevent steel wire rope to be twisted into speed reducer in real time, can guarantee that crane grab bucket is safely and efficiently operated.

The invention relates to a waterlogging electric shock risk early warning device for smart city management. A detection module detects electric field changes in water and air around a target area in real time, and monitors whether there is an electric shock hidden danger; the data processing module is used for receiving the signal of the detection module, processing and analyzing the signal and judging whether an electric shock risk exists or not; the alarm module sends an alarm signal and sends alarm information to the smart city management platform through the communication module; the communication module uploads the processed data to a smart city management platform through a wireless network or a wired network; the control module coordinates the work of each part of the device and optimizes the logic processes of detection, processing and communication; the power supply module supplies power; the cloud platform interface is in butt joint with a smart city management platform. Potential electric shock risks can be monitored in real time in the waterlogging environment, early warning is given out through the intelligent urban management platform, urban managers are helped to prevent electric shock accidents in advance, and the emergency response efficiency is improved.

This application discloses a frequency-modulated timing test system and method for sprint events, including a wireless starter, an infrared finish line detection device, a central control unit, and a display device. The infrared finish line detection device is fixedly installed at the finish line of the track, while the central control unit and display device are fixedly installed at the referee's stand. Each of the wireless starter, infrared finish line detection device, central control unit, and display device is equipped with a 2.4G wireless communication module and a 433M wireless communication module. During communication, when the number of communication failures due to interference in any frequency band reaches a preset threshold, the system automatically switches to another frequency band for retransmission, thereby effectively avoiding interference, significantly reducing the probability of communication failure, ensuring the real-time and reliable delivery of key commands, and thus guaranteeing the accuracy of timing and the fairness of the test.

The utility model relates to a remote supply optical cable for an underwater detector, which comprises an insulating layer, a plurality of optical units and a plurality of conductors are arranged in the insulating layer, an elastic body is filled in the insulating layer, an aramid fiber layer and an outer sheath are sequentially wrapped on the periphery of the insulating layer, each optical unit comprises a tightly-wrapped optical fiber or a fiber bragg grating, and copper-clad steel wires or copper wires or steel wires are adopted as the conductors. The elastomer is made of rubber or silicone rubber. The remote power supply optical cable for the underwater detector is compact in structure, the tightly packaged optical fibers are placed in the structural gaps of the conductors, on one hand, remote power supply can be provided for the detector, and on the other hand, detection signals can be transmitted and data can be collected in real time by utilizing stress borne by the optical fiber detection cable.
