Description
The utility model relates to a kind of switching device.
In fields such as family's electrical equipment control, Industry Control, in order to realize functions such as automatic management, scene and Long-distance Control, usually wish to adopt and a kind ofly can realize that manually with automatically control is compatible complementary, and when arbitrary switching function inefficacy, another switch still can realize controlling the switch of backup.Existing all kinds of switch is more, but does not have above-mentioned functions.For example, Chinese utility model patent discloses the appliance switch that a kind of name is called " energy-saving illumination switch " for No. 87201531.This switch mainly is made of selector switch and light-operated circuit, and it had both possessed the function of general lighting switch, possesses the function of optoelectronic switch again, and the gear by operation change over switch selector switch can allow it serve as optoelectronic switch or general lighting switch.Though this switch has certain characteristics, but still do not possess aforementioned functional.
The purpose of this utility model promptly provides a kind of compatible complementary manual electrical apparatus-switching device of backup formula of can realizing controlling manually and automatically.
The manual electrical apparatus-switching device of backup formula of the present utility model has manual selection switch, ON-OFF control circuit and input/output interface, it is characterized in that being provided with the DC power supply interface, the triggering signal input interface, circuits for triggering and relay switch, the fixed contact of described manual selection switch connects a contact of input/output interface, the fixed contact of relay switch connects another contact of input/output interface, the one gating contact of described manual selection switch and the normally-closed contact of relay switch join, another gating contact of manual selection switch and the normally opened contact of relay switch join, the power end of described DC power supply interface contact Power Generation Road and the power end of ON-OFF control circuit, the signal input part of described triggering signal input interface and circuits for triggering joins, the signal output part of described circuits for triggering connects the control end of ON-OFF control circuit, and the output of described ON-OFF control circuit is succeeded the power end of appliance switch.When using switching device of the present utility model, input contact in the input/output interface and outside source (or power supply) can be joined, output contact in the input/output interface and controlled electric appliance are joined, the control signal output ends of triggering signal input interface and external control device is joined.Like this, when making the trigger upset when the control signal input trigger circuit of external control device, controlled electric appliance and outside source (or power supply) are switched on or switched off; Simultaneously, also can the direct control manual selection switch, allow controlled electric appliance and outside source (or power supply) be switched on or switched off.Also that is to say, no matter by still direct control hand switch manually of external control device input triggering signal, all can allow controlled electric appliance and outside source (or power supply) be switched on or switched off, promptly whether the work of controlled electric appliance is controlled, thereby, improved the use flexibility of device for the user provides great convenience.In addition, in the process of using this device, when one of hand switch and relay switch were malfunctioning, another not out of order switch still can be realized controlled electrical appliances, hand switch and external control switch backup each other, corresponding reliability and the operability that improves device.
Therefore, switching device of the present utility model is compared with aforementioned existing product, has realized the manually complementary and fault backup with the compatibility of control automatically, has flexibility in the use, has higher reliability and operability simultaneously.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
Fig. 1 is the circuit block diagram of switching device among the embodiment.
Fig. 2 is an electrical schematic diagram.
As shown in Figure 1, the switching device in the present embodiment has manual selection switch 1, ON-OFF control circuit 2 and input/ output interface 3,4, and is provided with DC power supply interface 5, triggering signal input interface 6, circuits for triggering 7 and relay switch 8 especially.As shown in Figure 2, above-mentioned manual selection switch 1 is K switch, ON-OFF control circuit 2 is made of triode T and resistance R, input/ output interface 3,4 is contact e, f, DC power supply interface 5 is contact h, triggering signal input interface 6 is a contact 9, and circuits for triggering 7 serve as (adopting the 74HC74 type to trigger integrated circuit in this example) by trigger D, and relay switch 8 is switch JK.Wherein, the fixed contact i of manual selection switch K meets a contact e of input/output interface, the fixed contact j of relay switch JK meets another contact f of input/output interface, the gating contact a of manual selection switch K and the normally-closed contact c of relay switch JK join, another gating contact b of manual selection switch K and the normally opened contact d of relay switch JK join, the power end of DC power supply interface h contact Power Generation Road 7 and the power end of ON-OFF control circuit 2,9 signal input parts with circuits for triggering 7 of triggering signal input interface join, the signal output part of circuits for triggering 7 connects the control end of ON-OFF control circuit 2, and the output of ON-OFF control circuit 2 is succeeded the power end (being the power end of electromagnetic coil relay) of appliance switch JK.During switching device in using present embodiment, contact e and outside source (or power supply) can be joined, contact f and controlled electric appliance are joined, the control signal output ends of contact g and external control device is joined, the DC power supply of contact h and peripheral hardware is joined.The operation principle of switching device and process are as follows in this example: (1), can introduce outside triggering control signal by contact g and make trigger D change output state, base stage level by control triode T, make the emitter-base bandgap grading level upset of triode T, thereby the current switching of the solenoid among the control relay switch JK, the corresponding pass of touching of relay switch JK that allows contacts with Chang Kai or normally-closed contact, realizes the break-make control of controlled electric appliance and outside source (or power supply); (2), when hand switch K set when a touches, if the triggering control signal by the outside is connected the normally closed some c of relay J K, this switching device is the opening of conducting, otherwise, if make normal d connection battle of relay J K, this switching device is the closed condition for disconnecting then; (3), when hand switch K set during in the b contact, if the triggering control signal by the outside is connected normal battle of the d of relay J K, switching device is an off-state, on the contrary if normal battle of the c of relay J K connects, switching device then is a conducting state; (4), under the state that normally closed some c of relay switch JK connects, if with hand switch K set in a contact, then switching device is a conducting state, if with hand switch K set in the b contact, then switching device is an off-state.(5), under the state that normal battle of relay switch JK, d connected, if with hand switch K set in a contact, then switching device is an off-state, if with hand switch K set in the b contact, then switching device is a conducting state.(6), when ON-OFF control circuit or circuits for triggering break down or during Control Failure, can use hand switch K back up control according to aforementioned manner.
