Those which are off --- would require no or a small standby EU demand, while those which are on would --- require more. --- If the total demand is less than the available power they are all updated with the --- demand number. --- If any surplus exists from the PR nodes the batteries will be charged evenly with this. --- If the total demand requires draw on the batteries they will be discharged evenly. --- --- If the total demand is more than the available power all RE nodes will be shut down. --- We have a brown-out situation. --- --- Hence all the power distribution logic resides in this single node. --- --- Nodes connected to the network will have one or more of these parameters as meta data: --- <LV|MV|HV>_EU_supply : Exists for PR and BA node types. This is the EU value supplied by the node. Output --- <LV|MV|HV>_EU_demand : Exists for RE and BA node types. This is the EU value the node requires to run. Output --- <LV|MV|HV>_EU_input : Exists for RE and BA node types. This is the actual EU value the network can give the node. Input --- --- The reason the LV|MV|HV type is prepended toe meta data is because some machine could require several supplies to work. --- This way the supplies are separated per network. -technic.DBG = 1 -local dprint = technic.dprint +-- See also technic/doc/api.md -minetest.register_craft( - { - output = 'technic:switching_station 1', - recipe = { - {'technic:lv_transformer', 'technic:mv_transformer', 'technic:hv_transformer'}, - {'technic:lv_transformer', 'technic:mv_transformer', 'technic:hv_transformer'}, - {'technic:lv_cable', 'technic:mv_cable', 'technic:hv_cable'}, - } - }) +technic.networks = {} +technic.cables = {} +technic.redundant_warn = {} -minetest.register_node( - "technic:switching_station", - {description = "Switching Station", - tiles = {"technic_water_mill_top_active.png", "technic_water_mill_top_active.png", "technic_water_mill_top_active.png", - "technic_water_mill_top_active.png", "technic_water_mill_top_active.png", "technic_water_mill_top_active.png"}, - groups = {snappy=2,choppy=2,oddly_breakable_by_hand=2}, - sounds = default.node_sound_wood_defaults(), - drawtype = "nodebox", - paramtype = "light", - is_ground_content = true, - node_box = { - type = "fixed", - fixed = {-0.5, -0.5, -0.5, 0.5, 0.5, 0.5}, - }, - selection_box = { - type = "fixed", - fixed = {-0.5, -0.5, -0.5, 0.5, 0.5, 0.5}, - }, - on_construct = function(pos) - local meta = minetest.env:get_meta(pos) - meta:set_string("infotext", "Switching Station") --- minetest.chat_send_player(puncher:get_player_name(), "Switching station constructed.
