Embodiment
Below with reference to accompanying drawing, specific embodiments of the invention are described in further detail.
As Figure 1-3, the switch identification device of a kind of embodiment, comprises processor, and the test side of processor is connected with power supply VCC by pull-up resistor R.
As shown in Figure 1, in the time that the switch being connected with the outside of switch identification device is single-pole single-throw switch (SPST) S1, test side is by single-pole single-throw switch (SPST) S1 ground connection, power supply VCC is by pull-up resistor R and single-pole single-throw switch (SPST) S1 ground connection, wherein the stationary contact S1-2 of single-pole single-throw switch (SPST) S1 is connected with test side, and the disconnecting link stationary end S1-1 of single-pole single-throw switch (SPST) S1 is connected with ground.Certainly single-pole single-throw switch (SPST) S1 also can arrange like this: stationary contact S1-2 is connected with ground, and disconnecting link stationary end S1-1 test side connects.
As shown in Figure 2, in the time that switch is button B, test side is by button B ground connection, and power supply VCC is by pull-up resistor R and button B ground connection, and wherein, the first stationary contact B1 of button B is connected with test side, and the second stationary contact B2 is connected with ground; If when button B is normally closed button, wherein button B can adopt and often drive button or normally closed button.
Button B can be also locking press button, and its circuit theory diagrams are with often to drive button identical.
As shown in Figure 3, in the time that switch is double control switch, it comprises the first single-pole double-throw switch (SPDT) S2 and the second single-pole double-throw switch (SPDT) S3, the first single-pole double-throw switch (SPDT) S2 comprises the first stationary contact S2-2, the second stationary contact S2-3 and the first disconnecting link stationary end S2-1, the second single-pole double-throw switch (SPDT) S3 comprises the 3rd stationary contact S3-2, the 4th stationary contact S3-3 and the second disconnecting link stationary end S3-1, the first stationary contact S2-2 is connected with the second stationary contact S2-3, the 3rd stationary contact S3-2 is connected with the 4th stationary contact S3-3, the first stationary contact S2-2 is connected with the 3rd stationary contact S3-2, the disconnecting link stationary end S2-1 of the first single-pole double-throw switch (SPDT) S2 is connected with test side, and be connected with power supply VCC by pull-up resistor R, the disconnecting link stationary end S3-1 of the second single-pole double-throw switch (SPDT) S3 is connected with ground.
In the time that processor need to judge the type of switch, need user to split and put action work into.
In the time that single-pole single-throw switch (SPST) S1 is moved, if start single-pole single-throw switch (SPST) S1 in off-state, processor detects the voltage of test side, detect that stationary contact S1-2 is high level, by single-pole single-throw switch (SPST) S1 closure, stationary contact S1-2 is low level, if again single-pole single-throw switch (SPST) S1 is disconnected, stationary contact S1-2 is high level again, due to the physical construction reason of single-pole single-throw switch (SPST) S1, user is by after its closure, and then disconnected (or first disconnect again closed), its level jumps to low level from high level, and to jump to the transient state time t1 of high level longer again, conventionally can be more than 80ms (or more than 100ms, or more than 150ms) (if user only carries out closed procedure, can be considered as so transient state time t1 is endless), the needed time of corresponding level, its level oscillogram was as shown in the a1 in Fig. 4.
If button B is locking press button, if original state button B is off-state, what test side detected is high level, and button B presses, and test side detects low level, user presses button B again, button B upsprings, and test side detects high level, due to the decision of locking press button structure, its level jumps to low level from high level, and to jump to the transient state time of high level longer again, very approaching with above-mentioned transient state time t1.
In the time that button B is moved; if button B often leaves button; start processor and detect that the level of stationary contact B1 is high level; when button, B presses, and the level of stationary contact B1 is low level, release button B; the level of stationary contact B1 comes back to high level; its level jumps to low level from high level, and to jump to the transient state time t2 of high level conventionally shorter than transient state time t1 again, conventionally can be between 50ms-80ms, and its level oscillogram is as shown in the a2 in Fig. 4.If normally closed button, original state, what test side detected is low level, transient state time t2 jumps to the low level duration from low transition to high level again.
In the time that double control switch is moved, due to the special connection of double control switch, under original state, what processor test side detected is low level, move the first single-pole double-throw switch (SPDT) S2, disconnecting link is put the process of the first stationary contact S2-2 from the second stationary contact S2-3, test side temporarily detects high level, in the time that disconnecting link contacts with the first stationary contact S2-2, test side is again in low level, because the decisive action of the physical construction of single-pole double-throw switch (SPDT) (especially has the auxiliary single-pole double-throw switch (SPDT) of elastic force for some, its disconnecting link is in swing process, only being about to pendulum at it just departs from when the another one stationary contact and the contacting of original stationary contact completely), the process that disconnecting link is put the first stationary contact S2-2 from the second stationary contact S2-3 is very of short duration, its level jumps to the low level time from low transition to high level again, be that transient state time t3(is less than 20ms conventionally) be conventionally less than transient state time t2, be that its level oscillogram is as shown in the a3 in Fig. 4.Equally, the second single-pole double-throw switch (SPDT) S3 is carried out to operating process and result and the first single-pole double-throw switch (SPDT) S2 similar.
If Fig. 5 is a kind of circuit block diagram of Z-wave control terminal, it comprises Z-wave radio-frequency module, and above-mentioned switch identification device, adopt after this switch identification device, Z-wave control terminal can go to mate the type of outside connected switch simply, and the control method for dissimilar switch of Z-wave control terminal and relative software setting be set voluntarily, and do not need client to go manual setting, like this, only need to produce a kind of Z-wave control terminal, and assembling is for the software of dissimilar switch, can meet the coupling requirement of existing customer's dissimilar switch.
As shown in Figure 6, a kind of switch identification method, it comprises the following steps:
Processor calculates the transient state time between twice saltus step of outside connected switch level;
If this transient state time is less than first threshold, the type that judges this outside connected switch is double control switch;
If this transient state time is greater than first threshold and is less than Second Threshold, the type that judges this outside connected switch is often to drive button or normally closed button;
If this transient state time is greater than Second Threshold, the type that judges this outside connected switch is single-pole single-throw switch (SPST) or locking press button.
