Description

A single-chip microcomputer-based intelligent tool selection device and method

technical field

The invention relates to a quasi-intelligent selection device and method for tools based on a single-chip microcomputer, belonging to the field of electric asset management.

Background technique

Electrical equipment is divided into three states: operation, standby (cold standby and hot standby), and maintenance. The process of changing equipment from one state to another is called switching. By operating the circuit breaker, isolating switch, opening and closing the grounding knife or hanging and removing the grounding wire to convert the electrical equipment from one state to another or to change the operating mode of the system, this operation is called switching operation. In the power system, the switching operation is one of the most important tasks of the operators. The switching operation must implement the operation ticket system and the work monitoring system. The operation ticket is the embodiment of the operation task, operation intention and operation plan. It is the basis and key for the duty officer to perform switching operations.

The current switching operation process is: accept the advance order, fill in the operation ticket - check the correctness of the operation ticket - pre-control the dangerous point - accept the dispatch order - check the equipment naming - actual operation - operation report - sign off operation ticket. In the above operation process, after receiving the dispatching order and before starting the formal operation, the on-duty staff should put the tools and keys needed in this switching operation, such as safety helmets, multimeters, operating rods, grounding wires, The keys and the like are prepared at one time, which is the so-called preparation tool. the

At present, during the switching operation, the tools are temporarily prepared by the operator according to the content of the operation ticket before the official operation after receiving the dispatch order. However, due to the large differences among substations, the variety of tool types and key items, the large number of operation tickets for certain operation tasks, the lack of reconfirmation procedures, and other human factors, it is difficult to ensure that the tools are 100% ready for one time. , Missing and taking the wrong tools and utensils occurred frequently. Missing and taking the wrong tool artificially prolongs the outage time of the equipment, increases the operating time of the power grid in an abnormal mode, reduces the reliability of power supply, reduces the economy, and increases the risk of the power grid. At the same time, missing and taking the wrong tool may also lead to vicious misuse accidents.

Considering the actual situation of missing and taking tools and appliances, some power companies have issued preparation lists for using tools and appliances. After verifying that the operation ticket is correct, the on-duty staff counts the tools and keys needed for this operation according to the content of the operation ticket and personal experience, and fills it in the tool preparation form and approves it. When the operator prepares the tools after accepting the dispatch order, he shall prepare directly according to the list of tools and keys listed on the tool preparation list. Although through this organizational measure, the accuracy of tool preparation has been improved, it is still unavoidable to miss and take tools by mistake.

The patent with the publication number of 102968697A "A device and method for generating tool preparation sheets" discloses a tool preparation sheet generation device and its A generation method, the generation method first counts the types of tools and all keys of each substation, establishes a tool list set and a key list set, sorts out the tool preparation sheets corresponding to each typical operation task, and establishes a typical operation task tool for each substation. Equipment preparation list; then input the data in the above tool list set, the key list set, and the data in each typical operation task tool preparation list into the computer database; then input the typical operation task tool set in the previous step The preparation sheet generates the corresponding barcode, prints it out through the printing device, and pastes it in the typical task operation ticket; when the operator performs a typical operation task, scan the barcode of the typical operation task tool preparation sheet with a barcode scanner to obtain The key value of the barcode is automatically entered into the computer database, and the computer extracts the corresponding operation task tool preparation form from the database according to the barcode key value; finally, the operation task tool preparation form generated in the process is printed out by the printing device, and the operator is based on the output. The tool preparation list performs subsequent operations.

The above-mentioned tool preparation sheet generation method mainly relies on computer operation, and has the following defects:

1. Poor stability and reliability: under certain circumstances such as power outages in all substations, the computer also loses power, and the corresponding tool list database and software cannot be used; and if the computer in the substation is attacked by a virus, the computer hardware will age. For other reasons, the software may not be used normally;

2. Poor effectiveness: the background monitoring of the computer is switched to the desktop, which is not easy to operate;

3. The whole device has a large volume and is not easy to carry around, and the computer mainframe is placed in a fixed position, which is not conducive to moving, and the tools cannot be checked again.

In view of this, the inventor conducted research on this, and specially developed a device and method for intelligent selection of tools based on a single-chip microcomputer, and this case arose from this.
