[0002] The "two tickets" refer to the "operation ticket" and "work ticket," which are used to standardize operational procedures and ensure safe and standardized operations. These systems are designed to ensure the normal operation and maintenance of equipment, prevent equipment failures through regular inspections and tests, and improve production efficiency. This solution digitizes the "two tickets, three systems" and uses principles such as time clocks to electronically confirm the operating specifications of the "two tickets, three systems."

[0003] In the existing technology, the implementation of two-ticket operations is generally through reporting after the operator completes the operation. For example, before repairing electrical equipment, the staff needs to shut down the corresponding equipment first. After shutting down, mark the corresponding position of the work ticket form. Similarly, the maintenance personnel need to mark the corresponding position of the operation ticket. In the case of multiple repairs, there are many items in the work ticket and the operation ticket, which may cause confusion, making it tedious and laborious for the staff to check. Summary of the Invention

[0004] The present invention proposes a two-ticket work reminder circuit, which solves the problem that operators are not intuitive and conspicuous when filling out operation tickets and work tickets. The application of this solution has the effect of reminding staff while ensuring that it does not affect the normal two-ticket filling procedure, so that staff can be more aware of the equipment shutdown and maintenance progress.

[0019] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0020] A two-ticket work prompt circuit, which is attached to an electrical device as a separate battery-powered module, includes a power supply stabilizing module, a work ticket operation module and an operation ticket operation module. The input of the power supply stabilizing module is the power input V1, and the output of the power supply stabilizing module is connected to the inputs of the work ticket operation module and the operation ticket operation module. The work ticket operation module and the operation ticket operation module are connected in parallel, and the ends of the work ticket operation module and the operation ticket operation module are respectively provided with a first prompt unit and a second prompt unit.

[0021] In this application, the first prompt unit and the second prompt unit are connected in parallel with each other. The first prompt unit and the second prompt unit are generally lamps, LED tubes or buzzers, which can be directly connected to the corresponding positions of the circuit in series. The person who signs the work ticket is responsible for operating the first prompt unit. After turning off the equipment, turn on the corresponding switch at the work ticket operation module to light up the first prompt unit. After completing the maintenance, the maintenance personnel open the operation ticket operation module to turn on the second prompt unit. The maintenance personnel can judge the maintenance status through the first prompt unit and the second prompt unit.

[0022] As the instruction manual Figure 1 As shown in FIG2 , the power supply voltage stabilization module includes a voltage stabilizer U2. The input of the voltage stabilizer U2 serves as the power input V1 of the power supply voltage stabilization module. The GND pin of the voltage stabilizer U2 is grounded. The OUT pin of the voltage stabilizer U2 serves as the output of the power supply voltage stabilization module. The voltage stabilizer U2 can be a 5V output voltage stabilizer. The specific model and output voltage of the voltage stabilizer can be selected according to the applied power supply voltage and the operating voltage of the output matching prompt unit. The voltage stabilizer plays a role in ensuring the stability of the input voltage. The front end of the voltage stabilizer can be connected to a battery.

[0023] As the instruction manual Figure 1 As shown, the input of the voltage regulator U2 is connected to a resistor R2 and a capacitor C1 connected in parallel to ground, and the output of the voltage regulator U2 is connected to ground through capacitor C2. Resistor R2 and capacitor C1 act as a filter, ensuring that the voltage entering the voltage regulator is more stable and free from external interference.

[0024] As the instruction manual Figure 1 As shown, the work ticket operation module includes a switch K1, a resistor R1, and a first prompt element. The switch K1, the resistor R1, and the first prompt element are connected in parallel. The first prompt element includes a light-emitting diode or a light bulb, and the rear end of the first prompt element is grounded. When the switch K1 is pressed, the work ticket operation module forms a circuit, thereby illuminating the first prompt element.

[0025] As the instruction manual Figure 2 As shown, the ticket operation module includes a switch K2, a resistor R4, and a second prompt element. The switch K2, resistor R4, and the second prompt element are connected in parallel. The second prompt element includes a light-emitting diode or a light bulb, and the rear end of the second prompt element is grounded. When the switch K2 is pressed, the ticket operation module forms a circuit, thereby illuminating the second prompt element.

[0026] As the instruction manual Figure 1 As shown, the front end of the first prompt unit is grounded through an operation shutdown module. The operation shutdown module is used to automatically shut down the first prompt element and switch to the second prompt element after the operation ticket is opened. The operation shutdown module includes a transistor Q1, the base of the transistor Q1 is connected to the input of the second prompt element, the collector of the transistor Q1 is connected to the input of the first prompt element, and the emitter of the transistor Q1 is grounded.

[0027] When the switch K2 is powered on, the output of the transistor Q1 is a high voltage, so that the emitter and collector of the transistor Q1 form a path, short-circuiting the first prompt element and turning off the first prompt element.

[0028] The emitter of the transistor Q1 is grounded via a resistor R3 and a capacitor C3 connected in parallel, and the resistor R3 and the capacitor C3 play a filtering role.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
