Embodiment 1
[0035] Embodiment 1: In this example, the control mode of the main processor 9 of the pressure controller 5 adopts the time mode.
[0036] 1) After setting the control mode of the main processor 9 to the time mode through the key module, the main processor 9 sets 7 pairs of normal pressure values within a certain period of time (one time period corresponds to one pressure value, which is regarded as a pair), and a certain period of time The corresponding relationship between the time period and the normal pressure value is: when the time period is 0~7 o’clock (excluding 7 o’clock), the normal pressure value is 0.35Mpa; when the time period is 7~9 o’clock (excluding 9 o’clock), The normal pressure value is 0.5Mpa; when the time period is 9~11 o'clock (excluding 11 o'clock), the normal pressure value is 0.4Mpa; when the time period is 11~13 o'clock (excluding 13 o'clock), the normal pressure value is 0.5Mpa; when the time period is 13~17 o'clock (excluding 17 o'clock), the norma...
Embodiment 2
[0042] Embodiment 2: In this example, the control mode of the main processor 9 of the pressure controller 5 adopts the flow mode.
[0043] A. After the information processing center sets the main processor 9 to the flow mode through the RS485 communication module, the main processor 9 sets 3 to the normal pressure value in a certain flow section, and the corresponding relationship between the certain flow section and the normal pressure value is respectively: When the flow rate is 20~25 cubic meters / hour (excluding 25 cubic meters / hour), the normal pressure value is 0.35Mpa; when the flow rate is 25~30 cubic meters / hour (excluding 30 cubic meters / hour), the normal pressure The value is 0.4Mpa; when the flow rate is 30~35m3 / h (excluding 35m3 / h), the pressure is 0.5Mpa. When setting the flow section, the flow section can be segmented according to the actual situation. For example, take the flow rate of 5 cubic meters per hour to 50 cubic meters per hour as an example, and take ...
