With respect to prior art, the utility model has been obtained following beneficial effect: upper computer software runs on the controlling computer, the uninterrupted state that reads each FFU controller successively, by human-computer interaction interface the FFU state is offered the operator, and the operator is sent to on-the-spot FFU controller to the operational order of FFU; The FFU controller is installed on the FFU casing, receives the instruction from controlling computer, controls the rotating speed of FFU blower fan, and the running state of FFU is sent to controlling computer; FFU and controlling computer adopt RS485 bus communication network, and bus is cut apart the effect that concentrator plays signal relay and branch; The RS232/485 transducer is connected between controlling computer and the RS485 network, plays the function of electric interfaces conversion.
As improvement of the present utility model, this group control system also comprises Ethernet switch and a plurality of ADAM6050 module, and described upper computer software carries out communication by TCP/IP network interface and ADAM6050 module.Controlling computer in conjunction with setting in advance, is controlled the rotating speed of FFU and the level of ADAM6050 module DO mouth according to the level state of the DI mouth of the ADAM6050 module that reads automatically; Can also in conjunction with setting in advance, control the state of ADAM6050 module DO mouth automatically according to the FFU state that reads; The ADAM6050 module is passed through Ethernet switch, carry out communication with ICP/IP protocol and controlling computer, ADAM6050 provides 12 digital quantity inlet openings and 6 digital quantity delivery outlets as the part of FFU group control system, and the FFU group control system can be connected with other system in the building.
Described FFU controller is divided into interchange FFU controller or direct current FFU controller.
Described interchange FFU controller can adopt relay to switch the voltage that the auto-transformer tap changes supply FFU blower fan.
Described interchange FFU controller can adopt controllable silicon copped wave to change the voltage of supplying with the FFU blower fan.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Fig. 1 is a plan view of the present utility model.
Among the figure: 1, controlling computer, 2, the RS232/485 transducer, 3, bus cuts apart concentrator, 4, the FFU controller, 5, Ethernet switch, 6, the ADAM6050 module.
Embodiment
As shown in Figure 1, the group control system that is used for the monitoring of FFU blower fan of the present utility model, comprise controlling computer 1, its RS232 serial ports connects RS232/485 transducer 2, bus is cut apart concentrator 3 and is divided into 2 grades, upper level is connected on the RS232/485 transducer 2, next stage is connected to FFU controller 4, and controlling computer 1 is formed the TCP network with ADAM6050 module 6 by Ethernet switch 5.Upper computer software is installed in the controlling computer 1, carries out communication by computer RS232 serial ports and FFU controller, and the FFU controller is divided into interchange FFU controller and direct current FFU controller, and each FFU controller has 2 grades of unique numberings, numbering in group # and the group.Exchanging the FFU controller adopts the mode that relay switches auto-transformer tap or controllable silicon copped wave to change the voltage of supplying with the FFU blower fan.
During use, the operation upper computer software, software will send the instruction of reading the FFU controller state by the FFU number order, instruction is sent by computer RS232 serial ports, behind RS232/485 transducer 2, with the RS232 level conversion is the RS485 level, after the process bus is cut apart concentrator 3 again, each interchange FFU controller 4 is delivered in instruction.And instruction comprises the consistent FFU controller 4 of numbering will send oneself state information, status information oppositely is sent to controlling computer 1 with same circuit, when controlling computer is received return information, with information translation be literal, color etc. intuitively information be presented on the computer screen.Then upper computer software reads the state of next FFU controller by number order, when having read last FFU controller, and then reads the 1st FFU controller, thus the real-time update of realization FFU state.
