Definitions

the invention relates generally to communication devices and, more particularly, to a communication device whose power supply is a battery.
a fire alarm device has so far been provided as a communication device configured to be supplied with electric power from a battery and perform wireless communication (see Patent Literature 1).
the fire alarm device is installed in a building such as a dwelling and configured to alert people inside the building to a fire when detecting the fire. Therefore, in order to avoid battery exhaustion when alerting the fire, the fire alarm device periodically detects voltage of the battery to notify that when the voltage of the battery is less than or equal to a threshold, the battery needs to be replaced. The fire alarm device accordingly enables a user of the fire alarm device to replace the battery.
US 6,433,700 B1 describes an installation-activated, battery-powered hazard device with an on/off switch mechanism and separable into complementary portions.
a first of the portions contains essentially all operative electrical circuitry, including sensor(s), a source of power, and a circuit break feature; while its complement provides various small structures or morphology that aid or facilitate closure of the break. Cooperative functioning of the structures is consistent with a stylized mating or unmating of the portions.
the present invention has been achieved in view of the above circumstances, and an object thereof is to provide a communication device capable of extending the life of a battery.
a communication device is defined by independent claim 1 and preferred embodiments are described in dependent claims.
the communication device can extend the life of the battery.
a communication device 10 according to the Example 1 will be explained with reference to Figures 1 to 4 .
the communication device 10 is, for example a fire detector.
communication devices 10 and a management device 100 constitute a wireless communication system 1. Note that the communication devices 10 and the management device 100 are installed in the same dwelling.
Each of the communication devices 10 is configured to, when detecting fire, wirelessly transmit a fire detection signal representing detection of the fire to the management device 100.
the management device 100 is configured to, responsive to receipt of the fire detection signal, notify the detection of the fire to another device via the Internet or the like.
Each of the communication devices 10 is configured to be supplied with electric power from a battery 11 to be described later to operate in an operation mode as any one of a first operation mode for performing a normal operation including a communication operation with the management device 100 and a second operation mode for performing a stand-by operation, power consumption in which is smaller than that in the first operation mode.
Each communication device 10 is to operate in the second operation mode at the time of shipment.
Each communication device 10 is configured to, while supplied with the electric power from the battery 11 and operating in the second operation mode, change its own operation mode from the second operation mode to the first operation mode responsive to receipt of a changeover instruction from the second operation mode to the first operation mode from a user and to fulfilment of a changeover condition.
the wireless communication system 1 includes a maintenance device 101.
the maintenance device 101 is, for example a device provided for a service engineer (maintainer) requested to repair a communication device(s) 10, and configured to perform wireless communication with each communication device 10.
Each communication device 10 is configured to, while operating in the first operation mode, change its own operation mode from the first operation mode to the second operation mode responsive to receipt of a changeover message representing a changeover instruction to the second operation mode from the maintenance device 101.
a communication device 10 includes a main unit 10A, a battery 11 and an operation unit 12.
the main unit 10A is configured to be supplied with electric power from the battery 11 to operate in an operation mode as any one of a first operation mode and a second operation mode.
the main unit 10A includes a fire detector 13, a communication unit 14 and a controller 15.
the battery 11 is a power supply configured to energize and activate the communication device 10 and, for example a lithium battery.
the battery 11 is provided so as to prohibit removal of the battery 11 from the communication device 10.
the battery 11 is configured to supply the electric power to the operation unit 12 and the main unit 10A in the first operation mode. Specifically, the battery 11 will supply the electric power to the operation unit 12, the fire detector 13, the communication unit 14 and the controller 15.
the battery 11 is also configured to supply the electric power to the operation unit 12 and part of the main unit 10A in the second operation mode. Specifically, the battery 11 will supply the electric power to the operation unit 12 and the controller 15.
an operation state of the communication unit 14 while the communication unit 14 is supplied with the electric power is called a communication enabled state.
the operation unit 12 includes an operation button that allows the operation unit 12 to receive an operation from a user through.
the operation unit 12 includes a circuit (operation circuit) that is configured to be supplied with the electric power from the battery 11 to provide a signal to the controller 15 to be described later when the operation button is pushed.
the operation unit 12 is configured to, while the main unit 10A is supplied with the electric power from the battery 11 and is operating in the second operation mode, receive a changeover instruction as a result of a long push of the operation button by a user.
the operation circuit of the operation unit 12 will provide the signal to the controller 15 during the long push of the operation button.
the long push means that the operation button of the operation unit 12 is pushed for, e.g. one second or more. Note that the value is merely one example and the embodiment is not limited thereto.
the fire detector 13 is configured to detect fire, and examples thereof include a thermal detector, a smoke detector and a flame sensor.
the fire detector 13 is configured to be in the fire detection enable state during the first operation mode, and in the fire detection disable state during the second operation mode.
the fire detector 13 is configured to, when the operation mode is changed from the second operation mode to the first operation mode, be controlled with a processing unit 23 to be described later to change an operation state thereof from the fire detection disable state to the fire detection enable state.
the communication unit 14 is configured to then be controlled with the processing unit 23 to transmit to the management device 100 a communication start signal that represents starting communication. After the communication start signal is transmitted, the communication unit 14 is to wait a response signal representing receipt of the communication start signal-be in a waiting state.
the controller 15 includes, for example a microcomputer (microcontroller) as a main component and is configured to include predetermined functions by executing a program stored in a memory.
the program may be stored in the memory in advance or provided through a storage medium such as a memory card.
the controller 15 includes a first determining unit 21, a second determining unit 22 and the processing unit 23.
the second determining unit 22 is configured to, when the first determining unit 21 determines receipt of the changeover instruction by the operation unit 12, determine whether or not the changeover condition from the second operation mode to the first operation mode is fulfilled within a predetermined time period. Specifically, after the communication unit 14 transmits the communication start signal to the management device 100, the second determining unit 22 may determine whether or not the communication unit 14 receives the response signal from the management device 100 within the predetermined time period. The second determining unit 22 is configured to, when the response signal is received within the predetermined time period beginning at time of the transmission of the communication start signal, determine fulfilment of the changeover condition.
the second determining unit 22 is configured to, when the response signal is not received within the predetermined time period beginning at time of the transmission of the communication start signal, determine that the changeover condition is not fulfilled.
the predetermined time period is, for example 30 seconds. Note that the value is merely one example and the embodiment is not limited to this.
the processing unit 23 is configured to control and cause the main unit 10A to operate in an operation mode as any one of the first operation mode and the second operation mode. Specifically, the processing unit 23 is to cause the main unit 10A to operate in the second operation mode until the changeover condition is fulfilled with the changeover instruction received by the operation unit 12.
the processing unit 23 is configured to, when the first determining unit 21 determines receipt of the changeover instruction by the operation unit 12, change the operation state of the communication unit 14 from the communication disabled state to the communication enabled state. Specifically, the processing unit 23 is to start supplying the communication unit 14 with electric power from the battery 11 to activate and control the communication unit 14 so that the communication unit 14 transmits a communication start signal to the management device 100. According to this control, the communication unit 14 will transmit the communication start signal to the management device 100.
the processing unit 23 is configured to, when the second determining unit 22 determines fulfilment of the changeover condition, change the operation mode of the main unit 10A from the second operation mode to the first operation mode, and subsequently control so that the main unit 10A operates in the first operation.
the processing unit 23 is to activate the fire detector 13. Specifically, the processing unit 23 will start supplying the fire detector 13 with electric power from the battery 11. This allows the operation unit 12, the fire detector 13, the communication unit 14 and the controller 15 to be supplied with electric power from the battery 11. Thus, the operation state of the fire detector 13 will be changed from the fire detection disabled state to the fire detection enabled state.
the processing unit 23 is configured to, when the second determining unit 22 determines unfulfilment of the changeover condition, cause the communication unit 14 to operate in the communication disabled state. Specifically, the processing unit 23 is to stop the supply of electric power from the battery 11 to the communication unit 14 to deactivate the communication unit 14, and maintain the main unit 10A operating in the second operation mode.
the processing unit 23 is also configured to, when the communication unit 14 receives a changeover message from a maintenance device 101 with the main unit 10A operating in the first operation mode, change the operation mode of the main unit 10A from the first operation mode to the second operation mode. In this case, the processing unit 23 is to stop the supply of electric power from the battery 11 to the fire detector 13 and the communication unit 14 of the main unit 10A. Thus, the operation state of the communication unit 14 will be changed from the communication enabled state to the communication disabled state.
the communication device 10 may operate in the second operation mode at the time of shipment, and change the operation mode from the second operation mode to the first operation mode in response to a request from a purchaser (user) of the communication device 10 for causing the communication device 10 to detect fire.
the second determining unit 22 determines whether or not communication is successful or established within the predetermined time period (step S2). Specifically, the second determining unit 22 determines whether or not the communication unit 14 receives a response signal within the predetermined time period after the communication unit 14 transmits a communication start signal to the management device 100. In this case, the processing unit 23 changes the operation state of the communication unit 14 from the communication disabled state to the communication enabled state, and controls and causes the communication unit 14 to transmit the communication start signal to the management device 100.
the processing unit 23 changes the operation mode from the second operation mode to the first operation mode (step S3). Specifically, when the communication unit 14 receives a response signal within the predetermined time period beginning at time of the transmission of the communication start signal, the second determining unit 22 determines success in the communication-fulfilment of the changeover condition. When the second determining unit 22 determines the fulfilment of the changeover condition, the processing unit 23 activates the fire detector 13.
the processing unit 23 maintains the second operation mode (step S4). Specifically, when the communication unit 14 does not receive the response signal within the predetermined time period beginning at time of the transmission of the communication start signal, the second determining unit 22 determines failure of the communication-unfulfilment of the changeover condition. In this case, the processing unit 23 changes the operation state of the communication unit 14 from the communication enabled state to the communication disabled state. Specifically, the processing unit 23 stops the supply of electric power from the battery 11 to the communication unit 14 to deactivate the communication device 10, and then proceeds to process of waiting the changeover instruction.
the communication device 10 is the fire detector, but not limited to this.
the communication device 10 may be a device that is configured to detect intrusion (of an intruder(s)) into a dwelling when nobody is in, or a device configured to notify abnormality in a dwelling to a device outside the dwelling via the management device 100. That is, the communication device 10 needs to be a security device configured to be activated by the battery 11 to perform wireless communication with the management device 100.
the battery 11 in the embodiment may be included as a component of the communication device 10 or needn't be included as the component of the communication device 10.
the battery 11 may have a removable configuration, or be provided outside the communication device 10.
the communication device 10 receives the changeover instruction by a long push of the operation button in the operation unit 12, but is not limited to this.
the communication device 10 may receive the changeover instruction when the operation button of the operation unit 12 is continuously pushed a predetermined number of times.
the changeover instruction may be received when at least two operation buttons are pushed at the same time.
the communication device 10 changes the operation mode from the first operation mode to the second operation mode responsive to receipt of the changeover message from the maintenance device 101 while operating in the first operation mode, but is not limited to this. While operating in the first operation mode, the communication device 10 may change the operation mode from the first operation mode to the second operation mode when the changeover message from the maintenance device 101 is received with a predetermined operation being received.
the predetermined operation means, for example the operation button of the operation unit 12 being pushed.
the predetermined operation may be at least two operation buttons being pushed at the same time.
the communication device 10 receives the changeover message from the maintenance device 101, but is not limited to this.
the communication device 10 may receive the changeover message from the management device 100.
Example 1 a changeover condition is different from that in Example 1.
different points from Example 1 will be mainly described.
Like components are assigned the same reference numerals as depicted in Example 1 and explanation thereof will be omitted.
a main unit 10A of a communication device 10 includes an installation detector 16 in addition to the same components as those of the main unit 10A in Example 1.
the components included in the communication device 10 battery 11, operation unit 12, fire detector 13, communication unit 14, controller 15 and installation detector 16 are housed in an enclosure 10B of the communication device 10.
the battery 11 is configured to supply electric power to the operation unit 12 and the main unit 10A in a first operation mode. Specifically, the battery 11 is to supply the electric power to the fire detector 13, the communication unit 14, the controller 15 and the installation detector 16. The battery 11 is also configured to supply electric power to the operation unit 12 and a part of the main unit 10A in a second operation mode. Specifically, the battery 11 is to supply the electric power to the operation unit 12 and the controller 15.
an operation state of the installation detector 16 when the installation detector 16 is supplied with the electric power is called an installation detection enabled state
the operation state of the installation detector 16 when supplied with no electric power is called an installation detection disabled state.
a processing unit 23 in the present embodiment is configured to, when a first determining unit 21 determines receipt of a changeover instruction, change the operation state of the communication unit 14 from the communication disabled state to the communication enabled state and also change an operation state of the installation detector 16 from an installation detection disabled state to an installation detection enabled state. Specifically, the processing unit 23 is to start supplying the communication unit 14 and the installation detector 16 with electric power from a battery 11 to activate the communication unit 14 and the installation detector 16.
the processing unit 23 is configured to, when the communication is successful within the first predetermined time period and the installation of the communication device 10 is detected within the second predetermined time period, changes an operation mode from a second operation mode to a first operation mode, and subsequently performs operation control according to the first operation mode. Specifically, the processing unit 23 is to start supplying a fire detector 13 with electric power from the battery 11 to activate the fire detector 13. The battery 11 will supply the electric power to the fire detector 13, an operation unit 12, the communication unit 14, a controller 15 and an installation detector 16. Thus, an operation state of the fire detector 13 will be changed from a fire detection disabled state to a fire detection enabled state.
the first determining unit 21 determines whether or not the operation unit 12 receives a changeover instruction (step S30). Specifically, the first determining unit 21 is to determine whether or not a long push of an operation button in the operation unit 12 is performed.
the processing unit 23 changes the operation mode from the second operation mode to the first operation mode (step S33).
the second determining unit 22 determines whether or not the communication is successful, and then determines whether or not the installation is performed, but the present embodiment is not limited to this. The order of the determination may be reverse.
the operation state of the installation detector 16 becomes the installation detection enabled state, but the present embodiment is not limited to this.
Timing for causing the installation detector 16 to operate in the installation detection enabled state needs to be timing after the first determining unit 21 determines receipt of the changeover instruction and before the second determining unit makes a determination.
the communication device 10 operates in the second operation mode until it receives the changeover instruction and the changeover condition is fulfilled. It is accordingly possible to extend battery's life in comparison with the communication device 10 operating in the first operation mode.
the communication device 10 changes the operation mode from the second operation mode to the first operation mode responsive to a determination by the first determining unit and a determination by the second determining unit-two step determination. It is therefore possible to prevent changeover of the operation mode caused by a wrong operation such that a changeover instruction is entered by, for example a user operating the operation unit 12 in error. Note that removal of the battery 11 is not necessarily prohibited.
the communication device 10 includes the components described above, thereby capable of extension of the life of the battery 11 and prevention of the changeover of the operation mode caused by the wrong operation. In case the removal of the battery 11 is prohibited, electricity of the battery 11 will be consumed from the time of shipment. Therefore, the components described above are provided, and it is thereby possible to obtain a remarkable effect in comparison with a removable battery 11.
the communication device 10 determines the fulfilment of the changeover condition when the response signal is received within the predetermined time period beginning at time of the transmission of the communication start signal. Therefore, even if the changeover instruction is received with the communication with the management device 100 not available, the operation mode is not changed from the second operation mode to the first operation mode. Thus, the communication device 10 is able to prevent the changeover from the second operation mode to the first operation mode caused by a wrong operation and extend the battery's life.
the main unit 10A includes an installation detector 16 that is configured to detect installation of an enclosure 10B accommodating at least the main unit 10A and the processing unit 23.
the processing unit 23 is configured to cause the installation detector 16 to operate in an installation detection enabled state when the first determining unit 21 determines the receipt of the changeover instruction by the operation unit 12.
the second determining unit 22 is configured to determine the fulfilment of the changeover condition when the installation detector 16 detects the installation of the enclosure 10B within a predetermined time period beginning at the start of the operation of the installation detector 16 in the installation detection enabled state.
the second determining unit 22 is configured to determine unfulfilment of the changeover condition when the installation detector 16 does not detect the installation of the enclosure 10B within the predetermined time period.
the processing unit is configured to deactivate the installation detector 16 when the second determining unit 22 determines the unfulfilment of the changeover condition.
the communication device 10 is employed with the communication device fixed (installed) on a wall or the like in a dwelling. With the present configuration, the communication device 10 determines the fulfilment of the changeover condition when the installation detector 16 detects the completion of the installation within the predetermined time period beginning at the start of the operation of the installation detector 16 in the installation detection enabled state. Therefore, even if the changeover instruction is received with the communication device 10 not intended to be employed (with communication device 10 not intended to be installed), the operation mode is not changed from the second operation mode to the first operation mode. Thus, the communication device 10 is able to prevent the changeover of the operation mode caused by a wrong operation and extend the battery's life.
the processing unit 23 is configured to, when the first determining unit 21 determines the receipt of the changeover instruction by the operation unit 12, cause the communication unit 14 to operate in a communication enabled state, and control and cause the communication unit 14 to transmit a signal (communication start signal) to a management device 100 (external device).
the second determining unit 22 is configured to determine the fulfilment of the changeover condition responsive to receipt, by the communication unit 14 within a first predetermined time period beginning at time of the transmission of the signal, of a response signal to the signal transmitted from the management device 100.
the second determining unit 22 is configured to determine unfulfilment of the changeover condition when the communication unit 14 does not receive the response signal from the management device 100 within the first predetermined time period.
the processing unit 23 is configured to deactivate the communication unit 14 and the installation detector 16 when the second determining unit 22 determines the unfulfilment of the changeover condition.
the communication device 10 is employed with the communication device fixed (installed) on a wall or the like in a dwelling. Even if the changeover instruction is received with communication with the management device 100 not available and then the operation mode is changed from the second operation mode to the first operation mode, it is impossible to communicate with the management device 100. As a result, the battery will be consumed wastefully.
the communication device 10 determines the fulfilment of the changeover condition responsive to receipt of the response signal within the first predetermined time period beginning at time of the transmission of the communication start signal and to the completion of the installation detected within the second predetermined time period beginning at the start of the operation of the installation detector 16 in the installation detection enabled state.
the operation mode is not changed from the second operation mode to the first operation mode.
the changeover instruction is received with the communication device 10 not intended to be employed (with communication device 10 not intended to be installed)
the operation mode is not changed from the second operation mode to the first operation mode.
the communication device 10 is able to prevent the changeover of the operation mode caused by a wrong operation and extend the battery's life.
the main unit 10A includes a fire detector 13 that is configured to detect fire.
the processing unit 23 is configured to cause the fire detector 13 to operate in a fire detection enable state when the second determining unit 22 determines the fulfilment of the changeover condition.
the fire detector 13 will operate in the fire detection enabled state responsive to the two step determination. It is therefore possible to reduce a possibility that the fire detector 13 will operate in the fire detection enabled state responsive to a wrong operation.
the communication unit 14 is configured to receive a changeover message representing an instruction to change the operation mode to the second operation when the operation mode is the first operation mode.
processing unit 23 is configured to change the operation mode from the first operation mode to the second operation mode.
the processing unit 23 is configured to change the operation mode from the first operation mode to the second operation mode when the communication unit 14 receives the changeover message while the operation unit 12 receives a specific operation.
the communication device 10 does not change the operation mode from the first operation mode to the second operation mode.
the operation mode is not changed from the first operation mode to the second operation mode. It is therefore possible to prevent the communication device 10 from changing the operation mode caused by a wrong operation.
