Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a transmitting device, and particularly to a transmitting device that consumes little power and can be used for a long time with a battery.

As shown in Japanese Patent Application Laid-Open No. 63-118471, a lock confirmation device for windows and doors that detects the locked state of a lock device attached to an opening/closing part of a window and generates a signal is known.・This lock confirmation device for windows and doors is equipped with a battery and a solar cell battery, as well as a detection unit that detects the operating position of the lock shaft, and a transmitter that wirelessly transmits the detection signal of the detection unit. has a department. The detection section and the transmission section are operated using a solar cell battery as a power source, and the transmitted signal from the transmission section is input to the reception section provided apart from the windows and doors. Since the reception section displays the locked state, unlocked state, or semi-locked state of each window, the lock state can be centrally managed by the reception section of the management center.

However, since the conventional lock device described above uses a solar cell battery, the power obtained during wireless transmission is small. For this reason, it was not possible to transmit data over a sufficiently long distance by radio. In this case, if a large battery is used, the transmission output can be sufficiently increased, but a large battery cannot be attached to an opening/closing part such as a window or a door. However, even if a small battery is simply used, its power capacity is small and the battery will discharge below the required voltage level in a short period of time, making it impossible to use a small battery9.Therefore, this invention has been developed to reduce power consumption. It is an object of the present invention to provide a transmitting device that is small and can use a compact battery.

A transmitting device according to the present invention has a transmission control circuit, a state detection switch connected to an input terminal of the transmission control circuit, and a control terminal connected to the state detection switch. and a switching element that supplies power to the transmission control circuit when a signal from the state detection switch is applied to the control terminal, and a switching element that is connected to the output terminal of the transmission control circuit and transmits the signal supplied from the transmission control circuit to a remote location. and a switching means that stops the operation of the switching element after the transmission of the transmission means. The status detection switch has a plurality of detection switches connected to different input terminals of the transmission control circuit. The transmission control circuit is connected to the code number switching means, and supplies a signal representing the code number to the transmission means when receiving the signal from the state detection switch.

The switching element and the switching means constitute a self-holding circuit. The state detection switch has a first detection switch that generates an instantaneous pulse when switched, and a second detection switch that displays the state after switching of the first detection switch. The transmission control circuit is switched from the standby mode to the operating mode when power is supplied, and is switched from the operating mode to the standby mode when the operation of the switching element is stopped.

When the state detection switch connected to the input terminal of the transmission control circuit and the control terminal of the switching element is operated, the state detection switch generates an instantaneous pulse at the time of switching. Therefore, the switching element is turned on, power is supplied to the first transmission control circuit, and the transmission control circuit is switched from standby mode to operation mode. The transmission control circuit supplies a signal representative of the code number to the transmission means, and the transmission means transmits the signal supplied from the transmission control circuit to a remote location. For this reason,
The status of the status detection switch can be received at a remote location. Based on the output of the transmission control circuit, the switching means stops the operation of the switching element after the transmission of the transmission means.

The transmission control circuit is switched from the operating mode to the standby mode when the operation of the switching element is stopped.

In embodiments of the invention, the status detection switch may include a plurality of detection switches connected to different input terminals of the transmission control circuit to transmit various statuses to remote locations. In one embodiment of the invention, the switching element and the switching means constitute a self-holding circuit. The state detection switch has a first detection switch that generates an instantaneous pulse when switching, and a second detection switch that displays the state after switching of the first detection switch. Different signals can be transmitted through the transmitting means depending on the states of the detection switch and the second detection switch.

13).

The main lock 71 has a dead bolt 74 which is slidably attached so that its outer end 74a protrudes from and retracts from the case 73, as is well known. The deadbolt 74 has an inner end 74b in which a recess 74c is formed, and a pin 74d fitted in a long hole 73a of the case 73 is fixed thereto.

In the unlocked state in which the deadbolt 74 is retracted into the case 73, the tip of the arm portion 75d abuts against the edge 78a of the recess 74c. Therefore, when the door is struck, the deadbolt 74 is prevented from moving. When the arm portion 75d is rotated clockwise in FIG. 9 from the unlocked state, the tip of the arm portion 75d rotates within the recess 74c and then comes into contact with the front wall 74d of the recess 74c.

Further, when the arm portion 75d is rotated, the arm portion 75d
pushes the deadbolt 74 forward while sliding on the front 174d. Therefore, the outer end 74 of the deadbolt 74

a, and the door 72 is prevented from opening. Also,
The tip of the arm portion 75d is in contact with the edge 78b of the recess 74c. Therefore, when an impact is applied to the door 72, the deadbolt 74 is prevented from moving.

When the arm portion 75d is rotated counterclockwise in FIG. 9 from the locked state, the tip of the arm portion 75d is inserted into the recess
4c, it abuts against the rear wall 74e of the recess 74c. Furthermore, when the arm portion 75d is rotated, the arm portion 7
5d moves the dead bolt 74 rearward while sliding on the rear wall 74g. Therefore, the outer end 74a of the deadbolt 74 is retracted into the case 73 in an unlocked state as shown in FIG. In this manner, when the arm portion 75d moves between the locked position and the unlocked position, the compression spring 76 is compressed by the pin 75e provided at right angles to the arm portion 75d.
Since the pin 77 fixed to the case 73 is pressed in the direction of opening, a click feeling is obtained when the drive member 75 rotates, and the drive member 75 is held in the lock position or the unlock position by the elasticity of the compression spring 76. be done.

Thumb turn and cylinder locks are provided on the inside and outside of the drive member 75, respectively, by a known method. but,
In this invention, a novel thumb turn 80 and cylinder lock 90 shown in FIGS. 11 to 17 are installed.

3, and a cross-section locking part 89 provided at the other end of the rotating member 83. knob 8
The rotation member 83 can be rotated manually by pinching the rotation member 4 with fingers.

Since the locking portion 89 is inserted into the hole 75b of the drive member 75 and engages with the internal protrusion 75c, rotation of the knob 84 causes
The moving member 75 11a can be rotated both clockwise and counterclockwise. Two pairs of magnets 85 are attached to the rotating member 83 so that the door 72 can be selected between right-handed and left-handed.
a, 85b and 86a.

86b, and reed switches 87 and 88 are installed within the housing 81. The reed switch 87 constitutes the lock switch 65, and the reed switch 87
8 constitutes a lock state detection switch 25.

For example, in the right-hand door 72, when the knob 84 is rotated to the locked position, the magnet 85a turns on the reed switch 87, and the magnet 85b holds the reed switch 88 in the on state. Therefore, the reed switch 87 detects that the thumb turn 80 is rotated to the lock position, and the reed switch 87 detects that the door 72 is switched to the locked state.
8. For left-hand doors, magnets 86a and 8
6b is used.

Even if the locking portion 94 is fitted into the hole 75b of the drive member 75, the knob 84 of the thumb turn 80 can be freely rotated.

The key cylinder 93 is provided with a pair of magnets 95 and 96 that are arranged approximately diagonally apart from each other by an angle of 1.80''.Furthermore, the housing 91 adjacent to the circumference of the key cylinder 93 is provided with a reed switch 97. is provided.Therefore,
Even if the key cylinder 93 is rotated by the key in either the locking direction or the unlocking direction, the reed switch 97
is turned on, and the rotation of the key cylinder 93 can be detected. The reed switch 97 constitutes the control switch 62.

The locking member 89 of the thumb turn 80 has a cross section, and the locking portion 94 of the key cylinder 93 is formed in the shape of a flat protrusion.
Since the locking portion 94 is fitted with the internal protrusion 75c of the drive member 75 with some play, even if the thumb turn 80 is rotated to the lock position or the unlock position, the key cylinder 93 is not rotated. When the door lock device 70 is inserted and rotated, the thumb turn 80 follows and rotates, and the operation and locked or unlocked state of the door lock device 70 is detected.

When a predetermined armed state is reached by a signal received from the receiving means 101, the receiving means 10 of the transmitting/receiving control circuit 61 sends an output to the receiving means 53.
2 is connected to output port 0. Then, when the intended opening/closing part is in the locked state, the output port 02 to which the display means 103 that receives signals from each opening/closing part and displays the locked state is connected, and the receiving device 15 are in the armed state. The output port 04 is connected to an alarm output means 104 that generates an alarm signal when at least one of the opening/closing parts is illegally unlocked. The alarm output means 104 may use, for example, a telephone line 105 as shown in FIG.
Sound devices such as buzzers can be used. The reception control circuit 100 has storage means, signal discrimination means, armed signal generation means, and alarm signal generation means.

These means are program controlled.

The operation of the transmitting MU according to the present invention in the above configuration will be explained with reference to the operation sequences shown in FIGS. 20 and 21.

First, when all the opening/closing parts 11 in the house are locked, the circuit shown in FIG. 5 is activated based on the operation sequence shown in FIG. 20. When the handle part 12a of the locking device 12 is rotated in step 111 of FIG. 20, the handle part 12a resists the elasticity of the spring 23 and moves the detection part 20 from the unlocked position shown by the dotted line in FIG. 3 to the locked position shown by the solid line. Move to position. Therefore, the detection section activation switch 24 is momentarily turned on (step 112). Therefore, the cathode of the diode 34 shown in FIG. 5 becomes the ground voltage, so that the transistor 36 is turned on and the detection signal of the detection section activation switch 24 is applied to the input port of the transmission control circuit 31. As a result, the transmission control circuit 31
Power is supplied to the input port V through the switch to switch from standby mode to operating mode. Furthermore, when the transistor 36 is turned on, a trigger pulse is applied to the reset terminal R of the transmission control circuit 31 via the constant voltage circuit 40 and the pulse shaping circuit 41.8 Therefore, the reset I-means of the transmission control circuit 31 is reset. The timer means generates an output from output port 01 and turns on transistor 32 as shown in step 113 of FIG. Output port O
The output of □ is automatically stopped after a certain period of time (for example, one second) by the timer means of the transmission control circuit 31, and the transmission control circuit 31 is automatically switched from the operating mode to the standby mode.

While an output is being generated from the output port o8, the code number reading means of the transmission control circuit 31 reads the code number switching means 50.
The code number is read from input port L (step 114). At this time, since the lock device 12 is locked, the lock state detection switch 25 is turned on by the movement of the detection section 20. Therefore, the operation detection means of the transmission control circuit 31 detects the ON state of the lock state detection switch 25 (step 115), so the lock state detection means determines that the lock device 12 is in the locked state, and in step 116
In step 116, the signal forming means of the transmission control circuit 31 sends an output from the output port 02 to the transmitting means 51 to activate the transmitting means 51. The transmitting means 51 transmits a window code lock signal to the receiving device 15 (step 116). and a lock state display signal that indicates the locked state.

Next, the operation display means of the transmission control circuit 31 generates an output from the output port O3 to operate the operation display means 52. The operation of the operation display means 52 causes the light emitting diode to light up, making it possible to confirm the generation of the wind code lock signal (step 118).Furthermore, the process proceeds to step 119, and it is determined whether or not the timer means of the first transmission control circuit 31 has timed out. to decide. If the predetermined time has not elapsed in step 119, the process returns to step 118, and the operation display means 5
The operation in step 2 continues. When a predetermined period of time has elapsed, the output from the output port O1 of the transmission control circuit 31 is stopped in step 120, so that the 1 operation display means 52 is turned off. Also, since the output of the output port ○ is also stopped, the transistor 32 is turned off, and the transistor 36 is also turned off (
Step 121).

When the opening/closing part 11 inside the house is unlocked, the handle part 12 of the locking device 12 is opened in step 111 in FIG.
When a is rotated in the opposite direction, the detection section 20 moves from the locked position shown by the solid line in FIG. 3 to the unlocked position shown by the dotted line due to the elasticity of the spring 23 as the handle part 1.2a rotates. Therefore,
The detection unit activation switch 24 is momentarily turned on (step 112). Thereafter, steps up to Step 15 are the same as the above-mentioned locking case. In step 115, since the locking device 12 is unlocked, the lock state detection switch 25 is not activated due to the movement of the detection section 2o in the opposite direction. Therefore, the unlock detection means of the transmission control circuit 31 determines that the lock device W12 is in the unlocked state, and in step 117
Proceed to. In step 117, an output is sent from the output port 03 of the transmission control circuit 31 to the transmitting means 51 to activate the transmitting means 51, and the transmitting means 51 transmits a wind code unlock signal to the receiving device W15. The window code unlock signal includes a code signal including a code number indicating that it is a predetermined opening/closing part 11, a signal to distinguish between a window and a door, and an unlock state display signal indicating that it is in an unlocked state. including. Furthermore, the light emitting diode lights up due to the operation of the 1-operation display means 52, so that it is possible to confirm the generation of the window code unlock signal (step 118), and then the process proceeds to step 119, after which the process is the same as in the case of locking.

The circuit shown in FIG. 8 operates based on the operation sequence shown in FIG. 21. In this circuit diagram, a lock switch 65 and a cylinder lock 9 are turned on by operating the thumb turn 80.
Locking and unlocking operations of the door lock device 70 can be detected by any of the control switches 62 that are turned on by the 0 operation. That is, when the cylinder 090 is operated, the reed switch 97 forming the control switch 62 is turned on by the movement of the magnet 95 or 96 (step 131), and when the thumb turn 80 is operated,
85a, 85b, 86a, and 86b rotate, and the reed switch 87 that constitutes the lock switch 65 and the reed switch 88 that constitutes the lock state detection switch 25 are turned on (step 131), and when the cylinder lock 90 is operated, Mechanically, the thumb turn 80 is also operated in conjunction (step 131). In this case, a signal is provided to input port 11 indicating that cylinder lock 90 has been operated. Therefore, since the transistor 36 is turned on by operating the control switch 62 or the lock switch 65, the reset means and timer means of the transmission/reception control circuit 6 are activated, and the timer means generates an output from the output port 0□, and the transistor 36 is turned on. 32 is turned on (step 13
2), As a result, as in the case of FIG.
is supplied to switch from standby mode to operating mode. The code number reading means of the transmission/reception control circuit 61 reads the code number from the code number switching means 50 at the input port (step 134).

Next, in step 13, the operation detection means of the transmission/reception control circuit 61 determines whether the control switch 62 is turned on.
5) If the control switch 62 is turned on, the process proceeds to step 136, and the lock state detection means detects the door 7.
2 is in the locked state. The operation detection means of the transmission/reception control circuit 61 is activated when the lock state detection switch 25 is turned on.

Since the lock state detection switch 25 gives a signal indicating the lock state to the input port 2, the transmission/reception control circuit 6
The lock state detection means 1 determines that the lock state is present and proceeds to step 137. In step 137, the transmission/reception control circuit 6
The door open detection means 1 determines whether the door 72 is closed or not.

At this time, the door state detection switch 67 applies a signal indicating that the door 72 is closed to the input port I4. door 7
2 is closed, the process proceeds to step 138, and based on the output of the signal forming means of the transmission/reception control circuit 61, the transmitting means 5
1 transmits a door code control lock signal to the receiving device 15.

The door code control lock signal is transmitted to the specified door 72.
a code signal including a code number indicating that the
It includes a signal that distinguishes the door and a lock state display signal that indicates that the door is locked with a cylinder lock. Here, the operation detection means of the transmission/reception control circuit 61 enters a waiting state for receiving a signal from the receiving device 15 (step 139). When the receiving means 101 of the receiving device 15 receives all the lock signals, it gives an armed state display signal from the transmitting means 102 to the receiving means 53 of the transmission/reception control circuit 61 through the output port O1.

When the door 72 is unlocked, step 13 in FIG.
At step 6, the cylinder lock 90 is operated, the control switch 62 is turned on, and the lock state detection switch 25 is turned off. The unlocked state is detected by a high level signal at input port I2. Therefore, the process proceeds from step 136 to step 144, where the unlock state detecting means and signal forming means of the transmission/reception control circuit 61 sends a door code control unlock signal to the transmitting means 51 from the output port 03, thereby activating the transmitting means 51.

Next, proceeding from step 144 to 143, the activation detection means turns off transistor 36.32.

In step 135, if the control switch 62 is not turned on, the process proceeds to step 145, where the lock state detection means of the transmission/reception control circuit 61 determines whether the door 72 is in the locked state or not using the same means as described above. If the door 72 is not in the locked state, the process further advances to step 146, where the closed door detection means determines whether the door 72 is closed. When the door 72 is closed, the signal forming means performs step 14.
At step 7, a door code lock signal is generated, and the process proceeds to step 143. Door code lock signal.

and a lock state display signal indicating that the door is locked. The transmitting means 51 transmits a door code lock signal to the receiving device 15. In step 146 the door 72
If the door is opened, the process advances to step 143. When the door is in the unlocked state in step 145, the unlocked state detection means generates a door code unlock signal in step 148, and then proceeds to step 143. The door code unlock signal includes a code signal including a code number indicating that the door is a predetermined door 72, a signal indicating the door, and an unlock state display signal indicating that the door is unlocked with the thumb turn 80. include. Based on the output of the No. 3 forming means, the transmitting means 51 transmits a door code unlock signal to the receiving device 15. The output of the output port 01 is automatically stopped after a certain period of time (for example, one second) by the timer means of the transmission control circuit 61, and the transmission control circuit 61 is automatically switched from the operating mode to the standby mode.

Next, regarding the flowchart in Fig. 22, the receiving circuit 15
Explain the operation.

Initially, the reception control circuit 100 is in a reception standby state (step 151). In the reception standby state, when a radio wave signal is received from the transmitting means 51 of any opening/closing part 11 such as a window or a door, the process proceeds from step 152 to step 153. If there is no radio signal in step 152, the process returns to the start. In step 153, the received data is sent to the reception control circuit 1.
00 storage means, and then the reception control circuit 1
The signal determining means 00 determines whether the signal is a lock signal or an unlock signal (step 155). If a lock signal is received, the process proceeds to step 156, and a predetermined monitor lamp 180 corresponding to the door 72 shown in FIG. 18 is turned on. continue,
In step 157, it is determined whether or not the control signal is generated by the control switch 62 due to the operation of the cylinder lock 90. If it is a control signal, the process proceeds to step 158, and the receiving bag? The alarm signal generation means 115 determines whether or not an alarm signal is generated. Receiving device 1
When the alarm signal of the alarm output means 104 of No. 5 is being generated, the output of the alarm output means 104 is stopped in step 159, and then the process proceeds to step 1-60. Step 1
At 60, the armed signal generation means of the reception control circuit 100 activates the opening/closing section 11 based on the information stored in the storage means.
Determine whether all doors are closed. When all of the opening/closing sections 11 are closed, proceed to step 161;
The armed signal generation means of the reception control circuit 100 is switched to the armed state, and sends a feedback signal to the reception means 53 connected to the transmission and reception control circuit 61 through the transmission means 102 indicating that the armed state has been switched. The receiving means 53 that has received the feedback signal is the transmitting/receiving control circuit 6
1, and the transmission/reception control circuit 61 displays it on the armed display means 69. Thereafter, the process is shifted from step 162 to step 163. When the alarm signal from the alarm output means 104 of the receiving device 15 is not generated in step 158, the process is switched from step 158 to 160.

Thereafter, in step 165, the signal determining means determines whether or not the signal is a control signal generated by the control switch 62 due to the operation of the cylinder lock 90. In the case of a control signal, the process proceeds to step 166, where the reception control signal is
Armed state detection means 100 determines whether or not the device is in an armed state. If the armed state is maintained, the process proceeds to step 167, where the armed state is released and switched to the disabled state. After that, when the alarm signal of the alarm output means 104 is generated in step 168,
The alarm signal generation means stops the output of the alarm output means 104 in step 169 (step 169), and proceeds to step 163. When the control signal is not received in step 157, when all of the opening/closing parts 11 are not in the closed state in step 160, when the door is in the disabled state in step 166 km, and in step 168, the alarm output means 104 is activated. - If no signal is generated, proceed to step 163.

In step 165, if the control signal is not from the cylinder lock 90, the process proceeds to step 170, where it is determined whether or not the arm is in the armed state. In the case of the armed state, an alarm signal is generated from the alarm output means 104 in step 171, and then the process proceeds to step 163. If the state is in the disabled state in step 170, the process advances to step 163.
