Embodiment Construction
[0024] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.
[0025] as attached figure 1 Shown is the hardware configuration diagram, the control host 8 is equipped with "man-machine dialogue screen 5" MT4310, connected with the "PLC control module" and triggers one of the relevant "voice automatic recording and playback module" according to the steps of the voting process, after " "Voice Power Amplifier" emits the sound of singing votes from the loudspeaker. Every time the ticket counting enters the next step, n "wireless one-way code transmitters" that are equipped with n maintenance personnel must send process confirmation signals, and the corresponding n "wireless receivers" that match in the control host 8 receive the signals. After receiving and transmitting to the PLC control module, the PLC control module will confirm, and at the same time trigger the next process of the ticket-calling process to pe...

The invention relates to the monitoring of a power station maintenance order reading process and belongs to the field of power supply equipment maintenance. A safety collaboration control method for a power station transfer switching maintenance order reading process is characterized in that the method comprises the following steps that: a power station transfer switching maintenance process is started; when all maintenance personnel confirms, electrifying, cutting-off or other specific processes are selected; an order reading process is started to be played step by step through preset prompt voices recorded by a voice recording and playing module, and firstly the prompt voices for a first process are played; after the maintenance personnel completes operations prompted by the prompt voices, all maintenance personnel is required to complete the confirmation; a programmable logic controller (PLC) module is set to conduct a next order reading process only after the confirmation of all maintenance personnel is received, otherwise, the prompt voices for the process are repetitively played; after signals indicating that all maintenance personnel completes the operations are fully confirmed, a second order reading process is conducted and the prompt voices for the process are played; and the steps are cyclically repeated till all order reading processes are completed.
Description
technical field [0001] The invention relates to a ticket-calling process for maintenance of a power station, in particular to a safety collaborative control method and device for a ticket-calling process for switching maintenance of a power station. Background technique [0002] Over the years, Shanghai urban drainage enterprises have greatly improved their drainage capacity, advanced technology and reliability of technical facilities through many years of technical improvement. However, a series of maintenance procedures and measures for equipment in the urban drainage industry have not kept up, especially the safety awareness and rules and regulations of operators are still mostly on paper; relying on the consciousness of operators to maintain production safety has fallen behind Not on the trend of industry development. Due to the continuous alternation of new and old employees, people's contempt for safety rules and regulations, laziness, ignorance, lack of experience, e...
