Abstract
The present utility model provides novel vacuum display equipment. The equipment comprises a plurality of vacuum sensors, a touch screen and a switch power supply, the equipment is characterized in that the vacuum sensors are connected with the touch screen through RS-485 communication lines, and the switch power supply is respectively connected with the vacuum sensors and the touch screen. The novel vacuum display equipment is simple in structure, reliable in movement, convenient to maintain and low in costs.
Description
Technical field
The utility model belongs to the light fixture field, relates to the exhaust equipment of fluorescent lamp tube, especially the novel vacuum pressure display device.
Background technology
The vacuum meter that the vacuum pressure display device that is adopted on the exhaust equipment of present existing spiral fluorescent lamp fluorescent tube is produced for electronic device producer; For example " Alcatel ", " Lay precious " etc., this type of vacuum meter by vacuum transducer unit and change give, display unit constitutes, and the supporting use of two unit need; If fault need be selected the formulation accessory for use; Can't use other accessory replacements, this type of vacuum meter price is higher, causes cost of equipment maintenance high.
The utility model content
The technical matters that the utility model will solve is to overcome existing technical deficiency, and a kind of simple in structure, reliable in action, vacuum pressure display device easy to maintenance, with low cost are provided.
The utility model is achieved in that a kind of novel vacuum pressure display device; Comprise some vacuum transducers, touch-screen and Switching Power Supply; It is characterized in that: said vacuum transducer is connected through the RS-485 connection with touch-screen, and Switching Power Supply is connected respectively to vacuum transducer and touch-screen.
Said vacuum transducer is the vacuum transducer that has the RS-485 communication function, and said touch-screen is the touch-screen that has the RS-485 communication function.
Said Switching Power Supply is the 24V direct supply.
The advantage of the utility model novel vacuum pressure display device is: the utility model uses vacuum transducer and the touch-screen that has the RS-485 communication function; Can adapt to various brand vacuum transducers and touch-screen; Use flexibly, conveniently; Vacuum transducer quantity can be according to the request for utilization flexible configuration, and parts price is low, and maintenance cost is low.
Description of drawings
Combine embodiment that the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the one-piece construction synoptic diagram of the novel vacuum pressure display device of the utility model.
Embodiment
See also Fig. 1; It is the one-piece construction synoptic diagram of the novel vacuum pressure display device of the utility model; A kind of novel vacuum pressure display device; Comprise that three have the vacuum transducer of RS-485 communication function, the touch-screen that has the RS-485 communication function and 24V direct-current switch power supply; Said vacuum transducer RS-485 PORT COM is connected with the RS-485 PORT COM of touch-screen, and the power end that the Switching Power Supply output terminal is connected to vacuum transducer and touch-screen is vacuum transducer and touch-screen power supply.
Vacuum transducer has the RS-485 communication function, and it act as the system vacuum force value of site device and can carry out data transmission through the RS-485 communication port; Touch-screen has the RS-485 communication function, can carry out data transmission through the RS-485 communication port, and each vacuum transducer is sent instruction, receives data, is presented on the touch-screen; Switching Power Supply is DC24V output, is vacuum transducer and touch-screen power supply.
The principle of work of the utility model novel vacuum pressure display device is: at first touch-screen is carried out program design; Make it have the numerical value Presentation Function; Can show the vacuum pressure value in real time, have the parameter setting function, can set higher limit and the lower limit of each vacuum transducer and produce the output signal and make it have control function; Has the vacuum transducer calibration function; Can carry out atmospheric pressure, zero correction to vacuum transducer, then each vacuum transducer is installed in the system that need vacuumize, itself and touch-screen are linked in sequence; Be connected to the power end of vacuum transducer and touch-screen to Switching Power Supply DC24V output terminal, energising at last can normally be used equipment.
