A kind of proving installation that the embodiment of the invention provides all is provided with switch for the connection between each module, and like this, the user just can let corresponding switch closure realize different line connections as required, to accomplish various tests.Therefore, the embodiment of the invention can make the user realize the switching of measurement circuit easily, has saved the work that plugs a large amount of lines, has saved workload on the one hand, and the accuracy of measurement circuit switching is also very high on the other hand.
Because the proving installation that provides of the embodiment of the invention can be realized multiple measurement circuit, convenient for the purpose of, inner closed loop mode, communication module, Switching Module are disclosed below, from the measurement circuit and the implementation of listen mode and five kinds of test patterns of monitoring mode.
The another kind of proving installation that the embodiment of the invention provides; Can also comprise: first handover module; Be used for when receiving user's first control signal, making the 3rd K switch 3 and the 6th K switch 3 closures, and make that first K switch 1, second switch K2, the 4th K switch 4, the 5th K switch 5, minion are closed K7, octavo closes K8 and the 9th K switch 9 is broken off.First handover module can make proving installation realize measurement circuit as shown in Figure 3.Measurement circuit shown in Figure 3 is the measurement circuit of inner closed loop mode, and under this pattern, the inner pumping signal that produces is directly exported to inner acquisition module, convenient exploitation and debugging.This pattern is mainly used in the self-checking function of the proving installation that the embodiment of the invention provides.When generation is unusual before carrying out outside signal testing or in the test process, can encourage self diagnosis with acquisition function.
Fig. 4 shows the concrete structure of first handover module in the embodiment of the invention, comprises 7 phase inverters and 9 electromagnet.The break-make of using electromagnet to come CS is used phase inverter adjustment control signal.As shown in Figure 4, switch can be normal open switch, and is concrete, and when the signal in the input electromagnet was high level, electromagnet was started working, and makes corresponding switch closure, and when the signal in the input electromagnet was low level, electromagnet was no longer worked, and respective switch is broken off.When the user imported first control signal and is high level, the 3rd electromagnet KM3 and the 6th electromagnet KM6 started working, and made the 3rd K switch 3 and the 6th K switch 6 closures.Because the existence of phase inverter; The first electromagnet KM1, the second electromagnet KM2, the 4th electromagnet KM4, the 5th electromagnet KM5, the 7th electromagnet KM7, the 8th electromagnet KM8 and the 9th electromagnet KM9 do not work; First K switch 1, second switch K2, the 4th K switch 4, the 5th K switch 5, minion are closed K7, octavo closes K8 and the 9th K switch 9 is in off-state, connect so realize test circuit shown in Figure 3.Be understood that easily other measurement circuits connections also can be used similar mode to set and get final product.Concrete implementation does not limit this scheme that the embodiment of the invention provides, owing to be technological means well-known to those skilled in the art, for the purpose of making things convenient for, repeats no more.
Certainly, in practical application, octavo is closed K8 and the 9th K switch 9 might not be the entity switch, owing to belong to a kind of proving installation switch inside provided by the present invention, therefore octavo pass K8 and the 9th K switch 9 can be logic switch.
It is understandable that above electromagnet and the pairing switch of this electromagnet can use electromagnetic relay to replace, the principle of work of electromagnetic relay and effect and above electromagnet and this electromagnet to the principle of work of inductive switch with act on similar.In addition, the present invention does not limit and only uses electromagnetic relay, and other forms of relay (like solid-state relay, optical relay) all can be implemented in the present invention.
