The test figure of below carrying out according to technical scheme of the present invention for the inventor.
One, test general introduction
Name of product: revolve the nearly switch three core plug connectors of interlocking
Two, test objective
Plug connector water inlet mistaking signal causes locked signal to export console controller to, is the judgement that prevents whether this phenomenon from intaking to input signal on software, if water inlet is then transmitted messages alert signal to console controller.
Three, testing program
Pilot project: plug connector water inlet software identification.
Operating condition of test: the three core plug connector sockets and the plug that will revolve the nearly switch of interlocking separate, and let tap water or rainwater immerse socket.
Test principle: the voltage signal through DI channel multiplexing AI passage is discerned error signal.
Error signal scope: 0.5 ~ 14.6V (threshold voltage) or a little more than 14.6V.
The error signal determine mechanism: AI channel analog signal value is greater than 99 and less than 3890, and AI passage corresponding voltage value is greater than 0.5V and less than 19V.
Error signal identification back control strategy: controller sends the alerting signal of plug connector water inlet to console controller, and main frame is reported to the police, and operating grip control machine corresponding actions invalid (it is effective to beat safe bypass) is carried out motion limits.
Four, test procedure
1, machine is opened in the machine energising, will separate near the socket and the plug of switch three core plug connectors;
2, the water in the water pipe directly is poured in the three core sockets;
3, check whether the display screen of pilothouse the prompting of " water inlet of machine plug connector is reported to the police " occurs;
4, make machine in the situation that alarm is arranged and revolve the lock action, check whether machine can revolve latching operation, and the record actual conditions;
5, move machine having under the situation of alarm, check whether machine can carry out corresponding action, and the record actual conditions;
Whether 6, all checking actions drain water after accomplishing from the plug connector container, dry to check that display is reported to the police behind the water droplet and eliminate, and whether the machine action is normal, and the record actual conditions.
Five, test result and data analysis
Machine postpones three seconds output alarm signals to console controller after having detected into the water error signal, and console controller postpones two seconds output alarms to display after receiving alerting signal;
After revolving the identification of the nearly switch plug connector water inlet of interlocking software, machine is revolved latching operation accordingly, machine can't revolve lock, carries out motion limits, can play the protective action of safeguard protection through the identification of water inlet software;
After water drained in the plug connector socket, machine detected less than alarm release behind the water inlet error signal, and console controller does not receive error signal " water inlet of machine plug connector is reported to the police " and eliminates automatically.
Model at plug connector is identical, the inflow at plug connector place is identical, under the water quality condition of different, revolve the multiplexing AI channel signal value of lock signal DI (switch input) point from the machine controller monitoring and see the following form one.
AI tunnels analogy amount signal and magnitude of voltage through DI channel multiplexing can identify the affiliated substantially scope of the water quality that gets into plug connector, and judge whether to belong to normal signal, if belong to the restriction that error signal then moves to machine, thereby reach the effect of safeguard protection.
As shown in figures 1 and 3, be that the example of 24V is set forth the influence of water inlet to electric signal with the voltage of power supply E.Under the situation of ignoring equipment precision and systematic error, when the magnitude of voltage that water inlet causes controller to receive in the plug connector changes, Circuits System there is not influence between 0 ~ 0.5V, Circuits System does not process.
According to above-mentioned test findings; In water quality is under the situation of rainwater; The default value scope is set can be referring to table two and table three; Table two is to be the embodiment that partial Circuits System is provided with the default value scope to priority, and table three is to be the embodiment that the Circuits System of the first order is provided with the default value scope to priority.
In Fig. 3, plug connector is made up of plug and socket, and K switch is a sensor, and when switch closure, because plug connector plays the effect of lead, its resistance can be ignored, so the voltage that controller receives is supply voltage 24V;
After the plug connector water inlet, cause the resistance at plug connector place to increase, divide and removed a part of voltage, and then cause that the voltage that controller receives changes between 0 ~ 24V.
Table one
| Water quality type | AI channel analog signal value | AI passage corresponding voltage value |
| Tap water | 600~800 | 2.93~3.90 |
| Rainwater | 960~1100 | 4.68~5.37 |
| Salt solution | 3600~4000 | 17.58~19.53 |
| Not water inlet | 0~1 | 0 |
Table two
| Plug connector inflow V (ml) | The magnitude of voltage U (V) that controller receives | Fill order |
| 1＜V≤2 | 20≤U≤23.5 | Report to the police |
| 2＜V | 0＜U＜20 | Motion limits |
Table three
| Plug connector inflow V (ml) | The magnitude of voltage U (V) that controller receives | Fill order |
| 1＜V | 0＜U＜23.5 | Report to the police and motion limits |
As when the controller actual reception to magnitude of voltage when being 23.6V, regardless of the priority of this Circuits System in complete machine, this magnitude of voltage all is in error range, the inflow in this moment plug connector does not have influence to this Circuits System, Circuits System does not process.
When the controller actual reception to magnitude of voltage when being 21V; Exceeded error range; Inflow in the plug connector has produced interference to Circuits System at this moment; If the priority of this Circuits System in complete machine is the second level, the numerical value of this magnitude of voltage is in the first default value scope, the Circuits System processing of reporting to the police; If the priority of this Circuits System in complete machine is the first order, Circuits System is reported to the police and motion limits, thereby reaches the purpose of safeguard protection.
When the controller actual reception to magnitude of voltage when being 19V; Exceeded error range; Inflow in the plug connector has produced serious interference to Circuits System at this moment; If the priority of this Circuits System in complete machine is the second level, the numerical value of this magnitude of voltage is in the second default value scope, and Circuits System is carried out motion limits; If the priority of this Circuits System in complete machine is the first order, Circuits System is reported to the police and motion limits, thereby reaches the purpose of safeguard protection.
Whether in sum, the present invention provides Circuits System and signal protection method, can remind in time to intake in the subscriber's line and the size of inflow; And can accomplish to report to the police and/or motion limits; Prevent the generation of accident, simple in structure, dependable performance; Significantly improve operational security, reduced operating risk.
Those skilled in the art is to be understood that; In the operation of reality; Electric signal influence factor in the Circuits System is had a lot, and like model, water quality and the inflow etc. of pegging graft, those of ordinary skill in the art can form required default value scope according to specific circumstances.
The above is merely the preferred embodiments of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
