Description

A kind of time type central air conditioner control taximeter

Technical field

The utility model belongs to the central air conditioner technical field, relates in particular to a kind of time type central air conditioner control taximeter of the fan coil control that is used for central air conditioner.

Background technology

In the modern society, air-conditioning has been commonly used in life, and central air conditioner central cooling, heat supply are all installed in a lot of public places, end each user all is to control with fan coil, the function of its controller comprises refrigeration, heating mode setting, wind speed is provided with, room temperature is provided with, it is shown by LCDs, is illustrated in figure 1 as its workflow synoptic diagram, and existing controller generally is manual control, the user needs to regulate with button, operation inconvenience, and function is simple, does not also have billing function.

Summary of the invention

The utility model provides a kind of time type central air conditioner control taximeter, it not only has the function of original controller, also increases time clock feature, timing function, distant control function, LED-backlit function, outage memory function in addition and is connected transmit data functionality with computer.

For reaching above-mentioned purpose, the utility model adopts following technical scheme:

A kind of time type central air conditioner control taximeter, comprise CPU control module and peripheral circuit thereof, interconnect the temperature sensing circuit, the keypress function that cooperate with the CPU control module circuit, output control circuit and lcd output display circuit are set, described time type central air conditioner control taximeter is provided with in addition respectively with the CPU control module and interconnects the clock circuit that cooperates, regularly keypress function is provided with circuit, remote control testing circuit, LED-backlit output circuit, EEPROM memory circuit and RS485 communication interface circuit.

Adopt technique scheme, the utility model uses big LCD LCDs, contain microprocessor CPU and peripheral circuit thereof, possesses time clock feature, timing function, distant control function, the LED-backlit function, the outage memory function, RS485 communication interface circuit, control circuit, power circuit, it has increased time clock feature on the prior function basis, timing function, distant control function, the LED-backlit function, the outage memory function, and also have by RS485 communication interface circuit and be connected read data functions with computer, crossing the bus type connected mode by RS485 bus and computer expert links together, the current state of computer meeting each taximeter of timing acquiring, comprise on-off state, wind speed, the valve switch state, environment temperature and state of temperature is set, thereby value service time of each fan coil of accumulative total.

Fig. 2 is the workflow synoptic diagram of the utility model embodiment;

Fig. 3 is the circuit connecting relation synoptic diagram of the utility model embodiment.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

As Fig. 2, shown in Figure 3, the utility model embodiment, a kind of time type central air conditioner control taximeter, comprise CPU control module 1 and peripheral circuit thereof, interconnect the temperature sensing circuit 2 that cooperates with the CPU control module, keypress function is provided with circuit 3, output control circuit 4 and lcd output display circuit 5, described time type central air conditioner control taximeter is provided with in addition respectively and interconnects the clock circuit 6 that cooperates with the CPU control module, regularly keypress function is provided with circuit 7, remote control testing circuit 8, LED-backlit output circuit 9, EEPROM memory circuit 10 and RS485 communication interface circuit 11.

Its working method is: by the RC charge-discharge circuit, compare by the time that discharges and recharges with reference resistance, eliminate the error that some Yin Wendu or clock reference cause, thereby calculate current environment temperature, again by the wind speed of relatively judging fan coil of the temperature value set with the room and the on off state of water valve, reach the purpose of control room temperature, its control program is: by the IO mouth output control level of CPU, control the base stage of NPN triode.The triode conducting makes the relay coil energising when the output high level, produces magnetic, comes the adhesive contact, thereby reaches the power supply of control fan coil and electrically operated valve, controls their start and stop.

Adopt technique scheme, the utility model uses big LCD LCDs, contain microprocessor CPU and peripheral circuit thereof, possesses time clock feature, timing function, distant control function, the LED-backlit function, the outage memory function, RS485 communication interface circuit, control circuit, power circuit, it has increased time clock feature on the prior function basis, timing function, distant control function, the LED-backlit function, the outage memory function, and also have by RS485 communication interface circuit and be connected read data functions with computer, crossing the bus type connected mode by RS485 bus and computer expert links together, the current state of computer meeting each taximeter of timing acquiring, comprise on-off state, wind speed, the valve switch state, environment temperature and state of temperature is set, thereby value service time of each fan coil of accumulative total, complete machine integrates former controller and taximeter, the multiple function that increases is used more convenient in addition.

Claims

1, a kind of time type central air conditioner control taximeter, comprise CPU control module and peripheral circuit thereof, interconnect the temperature sensing circuit, the keypress function that cooperate with the CPU control module circuit, output control circuit and lcd output display circuit are set, it is characterized in that: described time type central air conditioner control taximeter is provided with in addition respectively with the CPU control module and interconnects the clock circuit that cooperates, regularly keypress function is provided with circuit, remote control testing circuit, LED-backlit output circuit, EEPROM memory circuit and RS485 communication interface circuit.
