In addition, in the construction cost estimating system of the present invention, the "equipment energy saving monitoring method" input through the energy saving service building unit is as shown in FIG. 3, wherein step 101 is to select the energy saving field of the monitoring device and input the field. The number of controlled devices, this step is for the energy-consuming equipment in the energy-saving field such as power, lighting, air conditioning, heat pump, solar photovoltaic, water saving, water supply and drainage, environmental control, etc. in the case to input the number of controlled devices. In step 102, if it is not a controlled device built into the system, step 103 is performed to analyze the technical rules for establishing energy-saving monitoring and interface measurement, and the energy-saving monitoring technical rule of the device is established and stored in the Excel table. In the middle, the Eli system calculates the number of energy-saving monitoring points and communication points of the controlled equipment. If the controlled device is built into the system, go to the step. 104, the system brings out the energy-saving monitoring function commonly used by the controlled device. Among them, common energy-saving monitoring functions include energy-saving temperature timing control function, air-conditioning system operation status alarm function or temperature value upper and lower limit alarm function.

Then, in step 105, it is up to the manufacturer to decide whether to use the measuring instrument to see if it is to be measured using an electric/water meter or other measuring instrument. If yes, proceed to step 109, input the type and quantity of the measuring instrument, and calculate the communication contact and the monitoring point of the measuring instrument according to the energy saving measuring technical rule in step 110, and standardize the digital electric meter in the energy saving measuring technical rule Establish connection and measurement signals, such as: check the hardware appearance of the device to provide two-wire RS485 communication pin (RS485+ and RS485-), check the communication protocol function of the device should support MODBUS/RTU format or set digital meter display The format of the values, etc., but should not be limited by this. At this time, in step 108, the sum of the energy-saving IO types and the monitoring points is accumulated, and the accumulated accumulated values are temporarily stored.

For example, the energy-saving construction technical rules include that the wiring topology of RS-485 must be Bus mode, and the number of connected stations or hardware drive capability can be up to 16 stations.

Then, step 205 is executed to calculate the model and quantity of the controller host and the expansion module, and calculate the brand, model and quantity of the controller/expansion module required for providing the energy-saving monitoring service. Finally, the system will display the type and quantity of the control device through step 206, such as: energy-saving control components, measuring instruments, controllers, sensors, etc. of the controlled device and the measuring instrument.

In addition, in step 203 of the fourth figure, "the controller/expansion module is added according to the economical energy-saving controller design rule", this step is the most economical calculation method, and the estimation process of the detailed calculation method is shown in FIG.
