Abstract
The utility model relates to an automatic industrial analysis meter or sulfur limiting meter with a gate control device, which is formed by that the inner part of a meter box body is provided with a balance, a sample disk and a furnace body, and a control circuit is connected between the meter box body and a manual control computer. The utility model is characterized in that the bottom of the meter box body is provided with a gate control signal micro-switch on a gate frame which is over against a box gate and is connected with a signal buffer of the manual control computer through the control circuit, and the manual control computer also has gate control signal-interrupt programs which can automatically alarm or automatically recover performance. The utility model has the advantages that the automatic industrial analysis meter or sulfur limiting meter eliminates completely the meter working disorder and bad results caused by manual intervention in the process of the coal sample experimentation, ensures that the meter is in a normal state for working with long time, enhances the accuracy of the experimental result, and has simple structure.
Description
Technical field: the utility model relates to the technical analysis instrument, is specifically related to test the architecture advances of the automatic industrial analytical instrument of coal sample and sulfur content thereof.
Background technology: present coal sample and sulfur content automatic industrial analyser, degree of accuracy improves the 0.01mg level level that reaches, and by means of computer control auto injection, measurement automatically, does not need manual intervention.But in the practice, be difficult to avoid fully artificial interference as: open in instrument chamber door, the test midway the sample dish such as moved at the work disorder that all can cause the high accuracy analysis instrument, cause and analyze the data gross mistake even may damage instrument.
Summary of the invention: at the above-mentioned shortcoming of background technology existence; technical problem to be solved in the utility model; be will provide a kind of can eliminate artificial test disorder, the data distortion phenomenon that gets involved automatic analytical test process and cause, and the automatic industrial analyser/constant sulphur appliance of the protection instrument band gating device avoiding damaging.
For this reason, the technical solution of the utility model is: a kind of automatic industrial analyser/constant sulphur appliance with gating device, be in instrument box, to be provided with balance, sample dish, body of heater, and and industrial computer between be connected with operation circuit and form, it is characterized in that: be provided with a gate-control signal switch between the chamber door of described instrument box and doorframe, this gate-control signal switch is connected with the signal buffer of described industrial computer by operation circuit.
Described gate-control signal switch is a microswitch, and is installed in the instrument box bottom on the doorframe of chamber door.
Owing to taked above-mentioned architecture advances, the utlity model has following advantage: eliminated manual intervention caused in the coal sample experimentation instrument work disorder and adverse consequences fully, guaranteed that the instrument long-term work in normal state, has improved the accuracy of experimental result; Simple in structure, realize having good social benefit and economic benefit easily.
Description of drawings: the utility model is explained below in conjunction with accompanying drawing.
Fig. 1 is an electromechanical structure principle schematic of the present utility model.
Fig. 2 is a gate-control signal interrupt routine block diagram of the present utility model.
Embodiment: as shown in Figure 1: a kind of automatic industrial analyser/constant sulphur appliance with gating device, be the electronic balance 5 that in instrument box 7, is provided with band weighing bar 3, automatic sample dish 2, body of heater 1, and and 9 of industrial computers be connected with operation circuit and form, it is characterized in that: described instrument box 7 bottoms are provided with a gate-control signal microswitch 6 over against the doorframe of chamber door 4, and this gate-control signal microswitch 6 is connected with the signal buffer 8 of described industrial computer 9 by operation circuit.
As shown in Figure 2: described industrial computer has also adopted following gate-control signal interrupt routine:
When the analytical test process is carried out a certain testing procedure i-see picture frame 10,
As do not have the gate look-at-me and enter-see picture frame 11-n, then industrial computer control is carried out follow-up test step I+1-and is seen picture frame 15;
Enter industrial computer-see picture frame 11-y if any the gate look-at-me, the implementation of industrial computer interrupt test step I immediately, and all measured datas are preserved enter in the storer-see picture frame 12;
When industrial computer record that the gate look-at-me is eliminated and gate in every data of having no progeny converge on interrupt before every data-see picture frame 13-y, industrial computer recovers to carry out the analytical test process of testing procedure i-see picture frame 10 from former interruptions;
If industrial computer records that the gate look-at-me is kept or gate in every data of having no progeny can not converge on interrupt before every data-see that picture frame 13-n, industrial computer keep interrupting at testing procedure i and the picture frame 14 that gives the alarm-see.
Now further specify as follows to the utility model course of work in conjunction with above-mentioned accompanying drawing:
To test with coal sample and be positioned in the instrument, after all are ready, close upper chamber door 4, this moment, chamber door 4 was fitted with gate controlled switch 6, high level is delivered to signal buffer 8, does not have the output of gate look-at-me in the signal buffer 8, and industrial computer 9 is carried out by the analytical test step control of former setting; And in outside or artificially intervention situation take place not close tight or test as chamber door 4, chamber door 4 opened etc., chamber door 4 breaks away from gate controlled switch 6, low level is delivered to signal buffer 8, output gate look-at-me is to industrial computer 9 in the signal buffer 8, industrial computer 9 is promptly according to the gate-control signal interrupt routine of setting: the interrupt test step, preserve measured data and enter storer, and further whether eliminate according to the gate look-at-me, whether data coincide before and after interrupting, or keep disrupted condition and give the alarm, or begin the execution analysis test process from interrupting testing procedure again, thereby avoid mistake to survey or instrument damage.
