Description
The present invention relates to a kind of equipment and method that produces and export a control signal, this equipment has a control device, and this control device produces this control signal by an input instruction signal; This equipment has an output unit, and this output unit is connected with a signal input part after the described control device, and it stores the described control signal of this control device, and this control signal is delivered to its signal output part to produce a release signal; This equipment has a verifying attachment that links to each other with this output unit, this verifying attachment reads out in the storage control signal in the retaking of a year or grade wiring of described output unit, and produces described release signal when this retaking of a year or grade control signal and described input instruction signal match.
By European patent document EP 0,120 339 B2 known this kind equipment.This kind equipment has a microcomputer as control device in a DV equipment, an output unit is connected on after this microcomputer.One by a command signal (process control instruction) control signal (director data) that is formed in this microcomputer is stored in this output unit.This output unit is answered passage through one and is connected with a verifying attachment (being made of described microcomputer equally).This microcomputer is read the described control signal that is stored in the described output unit as verifying attachment, and this is read control signal compare with the control signal that is generated.If two control signals are identical, this verifying attachment just sends a release signal so.This release signal arrives a relay coupling arrangement, this coupling arrangement is switched to described output unit with this release signal, and therefore facilitates when the release of this control signal is finished by another microcomputer on the signal output part of described control signal output at described output unit.The principle of work of this another microcomputer does not further elaborate.
The object of the present invention is to provide a kind of especially simply but very reliable working equipment, be used for producing and exporting a control signal that produces by an input instruction signal.
Purpose of the present invention is achieved like this in the equipment of the described type of this paper preface, promptly, described output unit has a relay, this relay is applied in the control signal that produces to some extent on the one hand and is applied in a sustaining voltage on the other hand again, make this relay when this control signal occurs, obtain a kind of state variation, and this new state is stored under the situation that applies the control signal that sustaining voltage storage produced.
A principal advantages of present device is its also simple so low-cost configuration, because only need a relay in order to store this control signal.Another advantage of present device is that this equipment is reliable especially, because after being added to described control signal and sustaining voltage on the described output unit, described control signal can be cut off, or described control device can separate with described output unit, because the relay status of Shi Xianing or stored control signal remained unchanged at that time.If have only the stored control signal of ability retaking of a year or grade when this control signal is cut off, can guarantee that then the control signal of institute's retaking of a year or grade always matches with the signal that in fact is passed to the signal output part of described output unit after release signal output.Different with the formerly disclosed equipment of the described type of this paper preface, in equipment of the present invention, need not the control signal that constantly repeats to upgrade institute's retaking of a year or grade by the retaking of a year or grade process.Because need not to bring in constant renewal in institute's retaking of a year or grade control signal and since the release of stored signal only after " correctness " of described control signal obtains guaranteeing, just be performed, so in present device, do not exist operating rate to require (this is an attendant advantages) to control device or verifying attachment yet.But in needs are brought in constant renewal in the equipment of control signal of institute's retaking of a year or grade (for example formerly disclosed equipment in), situation is far from each other, because when a wrong control signal is exported, must come very promptly discern a mistake, so that the consequence of a wrong control signal output is remained on minimum by means of a quick test device.
Especially simply and therefore the output unit that advantage is outstanding is characterised in that described relay is connected, is connected, is connected with the signal output part of described output unit with its relay output end with the retaking of a year or grade wiring of described output unit with a relay retaking of a year or grade wiring with an output terminal of described control device with its relay input end; Described relay will keep its new state after cutting off the control signal that is produced when it is applied in sustaining voltage, and therefore stored control signal is retained in its relay retaking of a year or grade wiring and its relay output end.
A with low cost and relay that have for the required switch performance of present device has a coil, and this coil is connected with this relay input end with an one wiring and is connected with a sustaining voltage input end of this relay by means of a normal opened contact by this coil control; This coil is closed this normal opened contact when control signal occurring.So such relay guarantees in simple mode, that is, and after applying a control signal and sustaining voltage, even if described control signal also keeps storing state when described control signal is cut off; Because for the described normal opened contact of closure with realize another time power supply of this coil and and then realize another time excitation of this coil, an of short duration excitation that just is enough to produce coil with described control signal by described sustaining voltage.
According to another improvement design of present device, suggestion, described verifying attachment is constructed like this, and promptly it produces another command signal by described retaking of a year or grade control signal; It is compared this another command signal with described input instruction signal; It produces described release signal when described two command signals are identical.The improved advantage of this of present device is its extra high reliability, because in order to produce described release signal, the command signal of being imported is compared with another command signal that signal by institute's retaking of a year or grade produces; Guarantee to have only the output terminal that in fact control signal that and input instruction signal match just is delivered to described output unit thus.
From the patent documentation of the described type of this paper preface, can know a kind of method that is used to produce and export a control signal, wherein, in a control device, produce this control signal by an input instruction signal; This control signal is passed to an output unit and is stored in this device; This storage control signal is read out from described output unit, and adopts described retaking of a year or grade control signal to produce a release signal under the condition of the command signal of considering to be imported; This release signal is passed to described output unit, and therefore facilitates the signal output part of described control signal output at described output unit.
Just be output in order to ensure the control signal of in such method, having only those and input instruction signal at that time really to match, the suggestion according to the present invention, before stored control signal is read out, interrupt the transmission that controls signal to described output unit that is produced from described output unit.
The principal advantages of the inventive method is: can be separated from each other described control device and output unit before reading stored control signal; If have only when this control signal is cut off the just stored control signal of retaking of a year or grade, so (as already mentioned) can guarantee that the control signal of institute's retaking of a year or grade is total and match with the signal that after release signal output, in fact is passed to the signal output part of described output unit.
If adopt a relay that described control signal is stored in the described output unit, that just can especially easily implement the inventive method.This relay has been applied in described control signal on the one hand and has been applied in a sustaining voltage on the other hand again, make this relay when this control signal occurs, obtain a kind of state variation, and this new state is preserved under the situation that applies the control signal that sustaining voltage storage produced.
The inventive method will be reliable especially, if produce a read-back order signal by described retaking of a year or grade control signal, this read-back order signal is compared with the command signal of being imported; When described two command signals are identical, produce described release signal.
