Embodiment
Below in conjunction with embodiment, the present invention is further described, and following embodiment is illustrative, is not determinate, can not limit protection scope of the present invention with following embodiment.
A kind of portable pressure transmitter data collector; shown in Fig. 1～3; comprise communicator 4; innovation of the present invention is: also comprise a portable power supplies; this portable power supplies comprises housing 8 and battery module; battery module is installed in the housing and its output terminal connects dress switch 7 (Fig. 2 of institute on the housing; K1 in 3) moving contact; a road of the first stationary contact A of this K switch 1 connects the transmitter connection terminal of being adorned on the housing 6; another road of the first stationary contact A of switch is connected communicator by the communicator connection terminal of being adorned on a current/voltage modular converter and the housing 5; the second stationary contact B of switch is connected the output terminal of transformer module by the transformer connection terminal of being adorned on a protection module and the housing 9, and the input end of transformer module connects 220 volts of civil powers.
In the present embodiment, the output voltage of battery module is 25 volts, and the current/voltage modular converter is one 250 ohm a resistance as shown in Figure 3.When the moving contact of K switch 1 contacted with the first stationary contact A, 24 volts of voltages loaded on the transmitter connection terminal and communicator connection terminal parallel with one another; When the moving contact of K switch 1 contacted with the second stationary contact B, battery module connected commercial power charged, and wherein battery module carries out current limliting and voltage-limiting protection by protection module when charging.
During use, operating personnel carry communicator and portable power supplies arrives on-the-spot, the terminal 2 of transmitter 1 is connected with the transmitter connection terminal of portable power supplies by cable 3, open communicator, moving contact with K switch 1 contacts with the first stationary contact A then, transmitter is exported a current signal according to the pressure signal in the pipeline, 250 Ohmages of this signal in portable power supplies are converted to voltage signal and are transported in the communicator, the display screen of communicator shows reading, so far operating personnel finish the data acquisition of a test point, constantly repeat said process and promptly finish whole test.
The present invention is simple in structure, easy to use, with the power supply portability, use accumulator that 25 volts of stable voltages are provided, and transmitter is connected by power supply with communicator, volume is little, be easy to carry, need not 220 volts commercial power interface, and the current/voltage modular converter in the power supply is voltage signal with the output transform of transmitter and directly is sent in the communicator, operating personnel can directly read the data of being gathered from the display screen of communicator, very convenient, shortened the test period of each point on the whole, improved work efficiency.
