Description
Technical field
The utility model relates to a kind of identification signal control system automatically.
Background technology
The high-tech product that code reader is combined closely as technology such as optics, machinery, electronics, software application is the main computer input apparatus of the third generation after keyboard and mouse.Code reader is utilized to obtain one-dimension code or Quick Response Code.And the signal control device of existing code reader cannot control alerting signal for a long time, and alerting signal and run signal cannot be operated simultaneously, in addition, just cannot continue when sending alerting signal to run sweep signal, needs restart or waiting signal terminates just to continue operation, cannot export the judgement signal that provide different information according to signal simultaneously.Therefore need badly and a kind ofly can change time of fire alarming according to the demand of different client and the automatic identification signal control system of alerting signal can be removed.
Utility model content
Technical problem to be solved in the utility model is the shortcoming overcoming the uncontrollable change time of fire alarming of code reader in prior art or remove alerting signal, provides a kind of identification signal control system automatically.
The utility model solves the technical scheme that its technical matters adopts: identification signal control system automatically, comprise on signal control circuit plate, signal control circuit plate and be provided with control chip, described signal control circuit plate is also provided with power input interface, signal input interface and signal output interface, control chip is connected with power input interface, signal input interface and signal output interface respectively, also comprise clock control circuit, described clock control circuit is connected with control chip.
Further, described signal input interface is at least two, and the number of signal output interface is at least two.
Concrete, described control chip is STC12C5A32S2.
The beneficial effects of the utility model are: structure is simple, are easy to manufacture, are easy to operation, can change time of fire alarming according to the actual requirements and remove alerting signal, save time, improve ease of use.The utility model is applicable to code reader.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein, 1 is signal control circuit plate, and 2 is control chip, and 3 is power input interface, and 4 is signal input interface, and 5 is signal output interface.
Embodiment
Below in conjunction with accompanying drawing, describe the technical solution of the utility model in detail.
As shown in Figure 1, automatic identification signal control system of the present utility model comprises on signal control circuit plate 1, signal control circuit plate and is provided with control chip 2, described signal control circuit plate is also provided with power input interface 3, signal input interface 4 and signal output interface 5.Control chip 2 is connected with power input interface 3, signal input interface 4 and signal output interface 5 respectively, also comprises clock control circuit, and described clock control circuit is connected with control chip 2.Power input interface 3 is connected with external power supply, is generally speaking connected with 220V alternating current; Signal input interface 4 is connected with code reader, and for receiving code reader signal, the client read wherein needs to arrange time of fire alarming and clear signal; Signal output interface 5 is connected with alarm, for output alarm signal.Concrete, described signal input interface 4 is at least two, the number of signal output interface 5 is at least two, namely can input time of fire alarming signal respectively by two paths of signals and eliminate alerting signal, then by two paths of signals output alarm time signal and elimination alerting signal, warning duration can be set according to user's request, or cancel alarm behavior.
Based on realizing effect and cost consideration, described control chip is the chip of STC12C5A32S2 model.
Principle of work of the present utility model is as follows: by being connected with the signal input interface on this automatically identification signal control system by code reader, and signal output interface is connected with alarm, control chip, by receiving the signal of code reader, then needs to arrange time of fire alarming and clear signal according to client.Thus, signal input interface and signal output interface can increase, and control chip can be changed, and signal control circuit board size can be changed, and time of fire alarming can be changed, and expand usable range of the present utility model, improve ease of use.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
