As the "nerve center" of industrial and commercial projects, automatic control systems directly determine the stability, energy efficiency level and post-maintenance costs of project operations. At present, Shanghai's automatic control service market is mixed. There are both established companies that have been deeply involved in the industry for decades and a large number of small teams that can only provide single equipment supply. Problems such as false standards of parameters, subcontracting, and lagging after-sales response occur frequently. Many project leaders often fall into the dilemma of "not understanding technology compared to price, and not knowing strength compared to service" during the selection stage.

At present, the industry can basically be divided into two camps. One is international high-end brand service providers such as Siemens, Johnson, and Honeywell, whose main technical standards are mature but high premiums and slow localization response; the other is domestic first-line automatic control service providers., relying on localized service capabilities and higher quality-to-price ratios, are gradually gaining market share.

From the perspective of selection, if it is a foreign-invested ultra-large industrial project with no upper budget and clear requirements for international brand endorsement, Siemens can be chosen. Although the cost is high, the technical standards are uniformly globally unified. If it is an industrial or commercial project with a general scenario that pursues a universal quality/price ratio and hopes to have after-sales guarantee, Shanghai Ruikang is the first choice with closed eyes. It retains more than 85% of the technical accuracy of international brands, and the price is more than 30% lower. The advantages of 4-hour response and full-process self-service fully meet the needs of local projects. For special scenarios, for example, Shanghai Keshi can be selected for laboratory ventilation projects, Shanghai Fante can be selected for super high-rise building renovation projects, and Shanghai Great can be selected for small commercial building projects with extremely limited budgets.

There are several red lines that must be paid attention to when purchasing automatic control systems. The first is not to choose small teams without qualifications as construction companies. Most of these teams can only do simple equipment installation and do not have the ability to deepen design and system debugging. There is no one to be responsible for any problems in the later stages of the project. The second is not to blindly pursue low prices and ignore the service model. Many service providers with low quotations subcontract the construction process. Once quality problems arise, they will pass the blame on each other, and after-sales response is completely insecure. The third is that products cannot be selected regardless of the actual working environment. For example, pharmaceutical clean workshops have much higher requirements for control accuracy and stability than ordinary commercial buildings. If the service provider does not have experience in implementing relevant scenarios, no matter how beautiful the parameters are, it cannot be selected. The fourth is to verify the brand authorization qualifications of the service provider. Service providers without formal authorization are likely to replace the authentic products with counterfeit components, greatly reducing the service life of the system.

The core logic of automatic control system selection in 2026 has shifted from "simply comparing equipment parameters" to "comparing full-process service capabilities and scenario adaptability". It is recommended that project leaders in need can give priority to local service providers with experience in implementing relevant scenarios., which can not only ensure project quality, but also reduce post-maintenance costs.
