The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Calculator room equipment control system as shown in Figure 1, Temperature Humidity Sensor interface 6, relay switch node 5, air-conditioning control module 7, nonvolatile storage 8 ﹑ internal temperature sensors 10 that main control system 1 comprises CPU9, is connected with CPU9, also comprise serial interface 12 that is connected with Surveillance center and the power circuit 11 that required working power is provided, main control system 1 is connected with controlled ventilation energy-saving equipment 2 by relay switch node 5, is connected with controlled air-conditioning equipment 4 by air-conditioning control module 7.Serial interface 12 can be RS232, also can be RS485, also can be RS422.In the present embodiment, serial interface 12 is RS232, adopts MAX3232, and CPU9 adopts LPC2132; Nonvolatile storage 7 adopts AT25F020.
Main control system 1 links to each other with external Temperature Humidity Sensor 3 on being installed in indoor suitable location through lead by Temperature Humidity Sensor interface 6, according to collecting the on-the-spot humiture data of returning, carry out break-make with the relatively back power supply of the value of setting by the 5 pairs of ventilation energy-saving equipments 2 of relay switch node on the main control system 1, simultaneously according to the wind locking that detects ventilation energy-saving equipment 2 air intakes and the air door state of air-out, judge whether operate as normal of ventilation energy-saving equipment 2, words are not closed ventilation energy-saving equipment 2, and by serial interface 12 alarm data are uploaded to Surveillance center.Main control system 1 can external some ventilation energy-saving equipments 2 and two air-conditioning equipments 4, finish the automatic control that two kinds of equipment are opened and closed.
In Fig. 1, main control system 1 links to each other with external Temperature Humidity Sensor 3 through lead by temperature sensor interface 6, and the latter can contain the voltage signal of information such as temperature, humidity to the former output, is converted into outside humiture reading through the CPU9 routine processes.By opening of device and the temperature and humidity bound when closing are set, detect external temperature and humidity by Temperature Humidity Sensor interface 6, the site environment data collected are deposited in the nonvolatile storage 8 after CPU9 handles compare with its setting value, according to energy-conservation logic decision, ventilation energy-saving equipment 2 and air-conditioning equipment 4 are carried out Selective Control with good conditionsi.
CPU9 links to each other with air-conditioning control module 7 (its air-conditioning control module comprises control modes such as switching node, agreement), CPU9 is according to data mode over reading, temperature data in the read-write nonvolatile storage 7, control air-conditioning start and stop automatically under the condition that is fit to, and judge whether normally operation of air-conditioning by variations in temperature, as: temperature continues to rise after opening air-conditioning, and temperature does not have downward trend after being separated by 6 minutes, judge by logic and then to think the air-conditioning fault, and and by serial interface 12 alarm data is uploaded to Surveillance center; CPU9 and internal temperature sensor 10 link to each other by control signal wire, read the voltage signal that contains temperature information, are converted into the internal temperature reading through the CPU9 routine processes; Power circuit 11 provides main control system inside chip power supply and relay working power.
The performance of the utility model main control system 1 can be divided into energy conserving system, control air-conditioning equipment, environmental monitoring three parts, by energy-conservation logic three parts is combined, and reasonably controls fully effectively utilization of energy conserving system.
Control procedure of the present utility model is as follows:
Monitoring indoor temperature and outdoor temperature when reaching controlled ventilation energy-saving equipment 2 and opening the bound of temperature, as outer temperature be 23 ℃, when interior temperature is 27 ℃, main control system 1 will at first be closed controlled air-conditioning equipment 4, switched on by the power supply of 5 pairs of controlled ventilation energy-saving equipments 2 of relay switch node then, and, judge whether normally operation of energy-saving equipment by the state that controlled ventilation energy-saving equipment 2 air inlet wind lockings and air outlet air door are fed back;
Monitoring indoor temperature and outdoor temperature when reaching air-conditioning equipment and opening the bound of temperature, as outer temperature be 26 ℃, when interior temperature is 30 ℃, main control system 1 will be closed controlled ventilation energy-saving equipment 2, according to controlled air-conditioning equipment 4 working forms of setting on the main control system 1, modes such as on/off, the control of infrared universal remote control, control air-conditioning panel on/off are carried out start and stop control to controlled air-conditioning equipment 4 then by agreement, A.C. contactor;
Monitoring indoor temperature and outdoor temperature is in low-temperature condition, be lower than 23 ℃ as indoor temperature, then do not open controlled ventilation energy-saving equipment 2 and controlled air-conditioning equipment 4, when indoor temperature is lower than the low-temperature values of setting, as be lower than 5 ℃, then open and heat logic, the heater by controlled air-conditioning equipment 4 heats communication equipment; When indoor temperature is higher than when setting high temperature values, as be higher than 40 ℃, then open high temperature and open logic by force, judge controlled air-conditioning equipment 4 faults again after, open controlled ventilation energy-saving equipment by force.
The utility model main control system 1 detects site environment by Temperature Humidity Sensor interface 6, reach a certain setting value and will control the open and close of ventilation energy-saving equipment 2 and air-conditioning equipment 4 respectively, because the ventilation energy-saving equipment low-temperature receiver is a natural cold air, refrigeration work consumption dwindles greatly than air-conditioning, thereby reaches the purpose of environmental protection and energy saving.
