Abstract
The invention discloses a laser cooling water automatic display and alarm system which can automatically monitor the water pressure of a plurality of laser cooling water systems, can display the water pressure in a centralized manner, can alarm when an abnormal phenomenon occurs and can indicate an abnormal water path. The system consists of a remote pressure gauge, a current-stabilizing power supply and a computer, wherein the remote pressure gauge is arranged on a cooling water pipe.
Description
The invention belongs to automatic tracer liquid pressure field, be specifically related to a kind of laser cooling water pressure and show automatically and warning system.
In atom method separation by laser uranium isotope large-scale experiment, laser instrument is a high power device, and its temperature height, thermal capacity are big.Therefore, water cooling system is important link.In the separation by laser hall, the quantity of laser instrument is a lot, and its chilled water can constitute a circulation.Present cooling water system is water to be extracted into the total main with certain pressure with water pump from tank, be branched off into again in being in charge of of each minute experiment hall, each road circulating water flow is through the water cooling labyrinth of each laser instrument, flows back to the tank that is above the ground level after the chilled water that flows out from each laser instrument gathers again.Like this, not only water inlet pipe has certain pressure, and water return pipeline also has certain pressure.
General flow circuit water alarm device all utilizes water delivering orifice not have the principle of pressure and designs.General flow circuit water alarm device in the laser cooling water system, all has certain pressure, so all can not adopt owing to total system.
At present the teletransmission tensimeter that uses generally is the variation that the change of resistance value that variation in water pressure is caused changes into electric current, and directly shows hydraulic pressure value by secondary instrument.Existing deficiency is to need a plurality of secondary instruments to show the cooling water pressure of a plurality of laser instruments to this method in the laser cooling water system if use, and is unfavorable for monitoring.
The object of the invention provides a plurality of laser cooling water system water of a kind of automatic monitoring pressure, and the energy centralized displaying, can report to the police when abnormal occurrence occurring, and can point out that the laser cooling water that unusual water route occurs shows and warning system automatically.
The technical scheme that realizes the object of the invention is to use the n great distance biography tensimeter more than or equal to 1 to be contained in n road laser cooling water inflow point, and join with n road relay switch, under the control of switching value output K, the variable resistor that the n great distance is passed in the tensimeter joins with stabilized current supply respectively, as load, change the pressure of chilled water into voltage signal, and transfer to the A/D converter that joins with stabilized current supply, A/D converter and computer interface join, computer interface joins with the computing machine that is provided with control and calculation procedure, computing machine obtains data from each road tensimeter successively, calculate corresponding water pressure, and judge whether to exceed normal value, send display screen to show corresponding water pressure value, if exceed then switching value output K control alarm equipment alarm of normal value, indicate corresponding cooling water channel to break down by being connected with computer interface.
Through test determination, when laser instrument normally moved, the pressure of chilled water was 0.15MPa, in case the cooling water pipe of laser instrument disconnects and metalling run out, hydraulic pressure will be dropped rapidly to 0.08MPa, and live when obstructed when the laser cooling water pipe plug, and hydraulic pressure will rise to more than the 0.16MPa rapidly.Therefore, 0.08MPa can be made as the lower limit of normal value, 0.16MPa is made as the upper limit of normal value.
Advantage of the present invention is that the chilled water of multi-station laser is concentrated monitoring and shown that each cooling water channel can be monitored and analyze automatically, and instant alarming notes abnormalities.Demonstrated fully the computing machine centralized control, the touring superiority that detects.
The present invention has following accompanying drawing:

Embodiment:
8 great distances that are contained in the laser cooling water water inlet are passed tensimeter 1 joins with No. 8 relay switches 2 respectively, by the switching value output K10 pilot relay switch 2 that joins with computer interface 5, variable resistor in the teletransmission tensimeter 1 is joined, as load 11 respectively with stabilized current supply 3.Variohm is housed in the water pressure gauge, and when hydraulic pressure was high, resistance value was big, and resistance value was little when hydraulic pressure was low, and according to the characteristics of stabilized current supply, the variation of load size does not cause the variation of the electric current of the load of flowing through, and direct ratio changes and the voltage at load two ends is with the variation of load.The size of hydraulic pressure is converted into the size of load 11 both end voltage in the cooling water pipe like this.Stabilized current supply 3 joins with A/D converter 4, A/D converter 4 joins with computer interface 5, computer interface 5 joins with the computing machine 6 that is provided with control and calculation procedure, and computer interface 5 also joins with switching value output K7, and switching value output K7 and alarm 9 join.
The circuit of stabilized current supply 3 (Fig. 2) is: adjust the collector of pipe T1 and the anode of 13 volts of power supplys and join, collector with triode T2 after base stage is joined by resistance R 3 and power positive end joins, emitter and the load 11 of adjusting pipe T1 are joined, the emitter of triode T2 joins by the anode of resistance R 4 with power supply, negative terminal by stabilivolt D and power supply joins, base stage is joined by the negative terminal of resistance R 2 with power supply, and joins with the emitter of adjusting pipe T1 by parallel resistor R1 and load 11.
The logic flow of the master control program (see figure 3) in the computing machine 6 is: initialization, selector channel, selected channel number is defeated by switching value output K10, variable resistor in the tensimeter of selected passage and stabilized current supply 3 are joined, obtain data by A/D converter 4, the magnitude of voltage that is obtained is calculated as corresponding force value, send display screen to show the force value of this passage, the upper limit value and lower limit value of this force value and setting is compared, then report to the police as if transfiniting, as if normally then selecting another passage and repeating monitoring, calculate and compare.
The flow process of the touring detection control program (see figure 4) in the computing machine 6 is: initialization, set the touring times N that detects, the line number when all over the screen of determining by display screen of N value is determined, show title, title can be a channel number, force value, monitor the hydraulic pressure and the demonstration of from 1 to n road (n is 8 this embodiment) successively, monitored one and judged whether itinerant monitor system after taking turns full N time, then continued monitoring successively discontented N time, full N then clear display screen return then show title also continuation monitor.
Each cooling water channel Monitoring and Controlling program (see figure 5) flow process is in the computing machine 6: beginning, send switching value to select the water route, start A/D converter and sampling, show the water route label, calculate hydraulic pressure value, show hydraulic pressure value, judge that hydraulic pressure is whether in critical field, then do not report to the police, in critical field, then carry out the monitoring in next water route in critical field.
Data acquisition control program (see figure 6) flow process is in the computing machine 6: beginning, sampling number N is set, selector channel, start A/D converter (A/D) sampling, judge that whether sampling number expires N time, then continues sampling if be discontented with, if full N time is then removed abnormal data, the way of removing is to remove a maximal value and a minimum value, averages, and is calculated as force value.
