[0059] Not installed on site: After the equipment has been shipped out and the on-site receipt and handover confirmation form has been submitted, but no on-site use confirmation has been carried out, it is considered to be in the "Not installed on site" state;

[0060] On-site use: After the equipment has been processed and the on-site use confirmation form is submitted, it enters the on-site use status; when on-site spare equipment and emergency equipment are used briefly, their status will not be changed, and only their use record information will be recorded;

[0061] On-site standby: After the equipment is shipped out, the shipment mode is on-site standby. After submitting the on-site receipt and handover confirmation form, it enters the on-site standby status;

[0062] Emergency standby: After the equipment has been cleared and the exit method is emergency standby, it will directly enter the emergency standby state;

[0063] On-site use: After using the equipment on-site and processing the on-site use confirmation form at the same location, it enters the on-site use state;

[0064] Returning to the destination: After the equipment has been processed and the on-site delivery handover form has been submitted, but before the receipt and handover confirmation form has been submitted, it is in the returning to the destination status;

[0065] The status of various equipment in the system will automatically jump according to the data transmitted from the test bench, and can also be changed manually.

[0066] Equipment outgoing management unit: used to handle outgoing operations for finished equipment, including: on-site use, on-site standby, and emergency standby;

[0067] On-site use: mainly for on-site application;

[0068] On-site spare: reserved on-site for use, usually with a spare mark, and the spare equipment is subject to the same maintenance cycle as the main equipment;

[0069] Emergency standby: mainly refers to equipment reserved for emergency use, such as failures caused by floods, earthquakes, landslides, etc. Emergency equipment cannot be used for other purposes.

[0070] The process of equipment delivery is as follows Figure 2 As shown in the flow chart,

[0071] Finished product delivery;

[0072] Record the reason for the issue in the system and whether specific use needs to be determined;

[0073] Reason for leaving the facility: choose finished product leaving the facility or emergency leaving the facility;

[0074] When finished products leave the laboratory, for equipment with a clear on-site usage location, such as replacement, replacement, or repair, the line name, station name, and usage location of the equipment should be recorded when leaving the laboratory;

[0075] Equipment outgoing records the reasons and other related information, and generates a list of finished equipment;

[0076] Is there a specific purpose?

[0077] No, just record the list and print the finished product labels;

[0078] On-site spare equipment can be directly labeled and sent to the site;

[0079] Confirm receipt on site;

[0080] Specific use is required.

[0081] Choose: On-site use or on-site backup

[0082] Select on-site backup, directly to no specific use;

[0083] Select on-site use;

[0084] Record the location, premises and purpose of use;

[0085] Transfer directly without specifying the purpose.

[0086] Emergency exit:

[0087] After the equipment is sent to the site, it enters the on-site emergency warehouse;

[0088] The system distinguishes on-site equipment and on-site spare equipment with black and red labels respectively;

[0089] Record relevant information such as the reason for emergency exit and generate an emergency equipment list;

[0090] Put it in the emergency storage.

[0091] like Figure 3 As shown, the equipment on-site operation management unit is divided into three parts: on-site standby, on-site use, and engineering equipment;

[0092] On-site backup:

[0093] When equipment used on site breaks down, in order not to affect driving, the spare equipment on site is used as a temporary replacement, and the reason for using the spare equipment, the location of use, and the road information are recorded;

[0094] After the corresponding replacement equipment is sent by the maintenance base, the temporary replacement spare equipment is unloaded and the unloading time, operator and other information are recorded; it is included in the unloading list, and can be loaded and returned to the maintenance base, received, and the process ends.

[0095] On-site use:

[0096] There are four general reasons for equipment used on site to be taken offline: overhaul, rotation repair, failure, and quality. For overhaul and rotation repair, the reasons for taking the equipment offline, the time of taking the equipment offline, and other related information must be recorded. A list of equipment to be taken offline is then generated, and the equipment is loaded and returned to the maintenance base, completing the process of receiving the equipment.

[0097] Engineering equipment: Engineering equipment refers to newly purchased equipment for the construction of new station lines. After the engineering equipment is installed on site, the maintenance base confirms the equipment information and the staff prints the equipment location barcode; records the usage location, time of use, purpose, and place of use, generates a list of equipment used, and ends the process.

[0098] When there is no Internet connection or relevant management software on site, it is used to manage the barcode alignment of equipment through mobile smart terminals. The mobile smart terminals are used to compile and print barcodes for equipment that has not been assigned codes on site. After the on-site data is entered, the mobile smart terminal synchronizes the data with the management software, realizing the synchronous management of on-site data.

[0099] Equipment alarm unit such as Figure 4 As shown, the equipment alarm unit is used for alarms for exceeding life span, exceeding maintenance cycle, emergency standby, and finished equipment.

[0100] (1) Excessive life alarm

[0101] When the equipment exceeds the set life span, the system will automatically alarm, and the alarm can be postponed through settings.

[0102] (2) Alarm for exceeding wheel maintenance period

[0103] When the equipment is used for more than the set maintenance cycle, the system will automatically alarm, and the alarm can be postponed through settings.

[0104] (3) Emergency backup alarm

[0105] If the emergency spare parts are stored in the warehouse for more than a certain period of time, they need to be re-inspected, and an alarm will be issued when the maintenance period is approaching.

[0106] (4) Finished equipment alarm.

[0107] The present invention carries out systematic and standardized management of the entire process of railway signal infrastructure and equipment maintenance, thereby improving the working efficiency of equipment maintenance.

[0108] The above content is a further detailed description of the present invention in conjunction with specific embodiments, and the specific implementation of the present invention should not be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
