Sodium hypochlorite preparation system capable of intelligently adjusting current density

The invention discloses a sodium hypochlorite preparation system capable of intelligently adjusting current density. The invention mainly relates to the technical field of sodium hypochlorite preparation systems. The system comprises a water softening device, a molten salt tank, a plurality of electrolytic cells, a plurality of direct-current power supplies, a plurality of control modules and a plurality of monitoring unit groups, the control modules read temperature information measured by a temperature sensor, flow information measured by a flow sensor and saline water concentration measuredby a concentration meter in a polling mode through a serial port, and the control modules can control the direct-current power supplies to be switched to an optimal current density according to intelligent matching of system program information data. Parameters like salt water concentration, softened water flow and temperature in the electrolytic cells are measured and displayed in real time through the control modules,
