The core value of weak current system maintenance is not to replace faulty equipment, but to plan the whole system operation, analyze the causes of problems, foresee problems in advance, eliminate hidden dangers and ensure the stable work of the system. This not only requires the maintenance unit to have the manufacturer's equipment supply resources and the manufacturer's core technical support, but also requires the field personnel resident in the maintenance unit to have rich on-site technical experience and experience in system management and planning, as well as good professionalism and professionalism.
