The utility model has the advantages of the single demarcation has been realized through ethernet switch, has avoided because voltage output is undulant or the manual operation causes the signal on different industrial computers inconsistent that the industrial computer that does not need moreover at every turn to mark the difference carries out iterative demarcation, has avoided manual operation's complexity.
Description
Technical field
The utility model relates to a kind of thickness measuring system, is specifically related to a kind of thickness measuring system of transmitted in both directions.
Background technology
Thickness measuring system is mainly used in the thickness of measuring metallic materials, is generally the thickness being detected metal material by industrial computer and signal gathering unit.If there is multiple stage industrial computer, when demarcating every platform industrial computer, output due to voltage has certain fluctuation, the magnitude of voltage that actual (real) thickness is corresponding has trickle fluctuation on different industrial computers, result in the thickness calculated on different industrial computer and have fine distinction, thus it is inconsistent to cause signal; Artificially each industrial computer is demarcated simultaneously and can strengthen the probability and increase complicacy of makeing mistakes.
The transmission of thickness measuring system from signal gathering unit to industrial computer is transmitted by 485 or 232 mostly, and this signal transmission is single, is all the magnitude of voltage of the current acquisition module of one-way transmission, cannot the ambient signal such as temperature of synchronous thickness measuring standard; The speed of this transmission mode is low simultaneously, cannot accomplish high-precision real-time, can cause the time delay of Signal transmissions.
Utility model content
For the problems referred to above, in order to overcome the defect of prior art, the purpose of this utility model aims to provide a kind of reliability thickness measuring system high and simple to operate.
To achieve these goals, the utility model adopts following technical scheme: a kind of thickness measuring system of transmitted in both directions, comprise industrial computer, signal gathering unit and Ethernet switch, described industrial computer is all connected with Ethernet switch with signal gathering unit, described signal gathering unit is used for obtaining voltage signal according to the quantity of X-rays X in the ionization chamber of outside, and described voltage signal is sent to industrial computer by Ethernet switch; Described industrial computer is used for obtaining demarcation signal according to voltage signal, and demarcation signal is sent to signal gathering unit, makes signal gathering unit obtain thickness signal according to demarcation signal and voltage signal.
As preferably, described signal gathering unit also comprises the display unit corresponding with signal gathering unit, and described display unit is connected with Ethernet switch.
As preferably, also comprise electric control unit, described electric control unit is connected with described Ethernet switch.
As preferably, also comprise external communication unit, described external communication unit is connected with described Ethernet switch.
As preferably, described signal gathering unit quantity is for being no more than 8.
Compared to existing technology, the beneficial effects of the utility model are that achieving single by Ethernet switch demarcates, avoid because voltage output pulsation or manual operation cause the signal on different industrial computer inconsistent, and do not need to demarcate the demarcation different industrial computers being carried out to repetition, avoid manually-operated complicacy. at every turn
Accompanying drawing explanation
Fig. 1 is function structure chart of the present utility model.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
As shown in Figure 1, a kind of thickness measuring system of transmitted in both directions, comprise industrial computer, signal gathering unit and Ethernet switch, industrial computer is all connected with Ethernet switch with signal gathering unit.
When carrying out measurement thickness of strip, the voltage signal that described industrial computer is collected by reading signal gathering unit is demarcated, demarcation terminates rear transmission nominal thickness signal to signal gathering unit, signal gathering unit receives nominal thickness signal combination voltage signal and obtains thickness signal, again the thickness signal calculated is sent to industrial computer, thickness signal here contains one-tenth-value thickness 1/10.
The thickness measuring system of described transmitted in both directions also comprises the display unit corresponding with signal gathering unit, and described display unit is connected with Ethernet switch.
Described bidirectional transmission system also comprises electric control unit and external communication unit, and described electric control unit is all connected with Ethernet switch with external communication unit.Ethernet switch is connected with outside terminal device by external communication unit, and thickness information can be sent to outside terminal device by external communication unit by Ethernet, and the contact realizing information is mutual
Described signal gathering unit is that the ray sent by X-ray radioactive source passes band, band absorption portion ray, unabsorbed ray hits ionization chamber and ionizes, produce one becomes certain relation voltage signal with the quantity of X-rays X hitting ionization chamber, the voltage signal that ionization chamber produces amplifies after process through amplifier, be sent to A/D converter and convert digital signal to, then carry out filtering process and obtain final voltage signal, be synchronized to Ethernet switch.
Described industrial computer receives Ethernet switch voltage signal synchronously, voltage signal is demarcated simultaneously, store demarcation signal and pass through the synchronous demarcation signal of Ethernet switch to signal gathering unit, described signal gathering unit is decoded to demarcation signal, obtains thickness signal in conjunction with voltage signal; Described display unit is for showing the real-time thickness value of respective signal collecting unit, and display unit can be known according to prior art according to the know-why of thickness information display one-tenth-value thickness 1/10.
It should be noted that, described demarcation is the model according to the standard recorded in system, the voltage signal received is obtained corresponding thickness, using this demarcation signal as benchmark; Such as, the voltage signal received is 1V, and the thickness that in standard jig, 1V is corresponding is 0.4cm, just with this signal for benchmark one-tenth-value thickness 1/10 after this; After this THICKNESS CALCULATION, just without the need to again demarcating, only needing an industrial computer to make single and demarcating, calculating corresponding thickness using demarcation signal as reference.
It should be noted that described signal gathering unit inside is integrated with technical grade arm processor, arm processor makes signal gathering unit have the function processing and obtain thickness signal, in conjunction with the environmental factor comprising temperature etc., calculate real-time thickness signal and be synchronized to Ethernet switch again;
