Description

The present invention relates to a wireless air conditioning control system that wirelessly sends measurement data such as temperature and humidity to an air conditioning controller and performs air conditioning control based on the wirelessly transmitted measurement data, and an air conditioning controller used in the wireless air conditioning control system It is about.

  Conventionally, air conditioning control sensors (eg, temperature sensor, humidity sensor, sensor / setting device, etc.) have been used for the purpose of simplifying construction, improving the degree of freedom of installation location, and facilitating response to layout changes. Wireless communication is progressing. These sensors are called wireless sensors and are connected to an air conditioning controller via a wireless line to constitute a wireless air conditioning control system.

  FIG. 6 shows an outline of a conventional wireless air conditioning control system. In the figure, 1 is a wireless sensor, 2 is an air conditioning controller, 3 is a monitoring device, and the monitoring device 3 and the air conditioning controller 2 are connected via a network 4. The wireless sensor 1 is a temperature sensor, for example, and is connected to the air conditioning controller 2 by a wireless line. Note that wireless communication between the wireless sensor 1 and the air conditioning controller 2 is unidirectional from the wireless sensor 1 to the air conditioning controller 2.

  Another conventional wireless air-conditioning control system uses a two-way wireless line, but the purpose of communication from the air-conditioning controller to the wireless sensor is to return the reception confirmation signal (ACK) for the measurement data transmission from the wireless sensor. It is limited to the transmission of display data to the wireless sensor / setting device, the change of constants in the sensor during installation work, and the like.

  In this wireless air conditioning control system, measurement data (temperature data in this example) is sent from the wireless sensor 1 to the air conditioning controller 2. The air conditioning controller 2 receives measurement data from the wireless sensor 1 and performs control calculation based on the measurement data, and performs VAV (variable air volume adjustment unit), FCU (fan coil unit), AHU (air) (not shown). Control of air conditioning equipment such as harmony machines. In addition, the air conditioning controller 2 sends measurement data sent from the wireless sensor 1 to the monitoring device 3 via the network 4. The monitor monitors the control state of the air conditioning control by displaying measurement data sent from the wireless sensor 1 on the screen (monitoring screen) of the monitoring device 3.

  In this wireless air-conditioning control system, the wireless sensor 1 is battery driven in order to eliminate not only the signal line but also the power supply line. For example, a replaceable battery such as a dry battery is used as the battery. When the wireless sensor 1 is driven by a battery, it is required to reduce power consumption as much as possible in order to extend the battery life.

  Therefore, for example, in Patent Document 1, a timer that periodically generates a drive signal is provided in the wireless sensor, and each time the timer generates a drive signal, the circuit main unit including the communication unit is in an operating state for a predetermined time. And so on. As a result, the operation and pause of the circuit main part are repeated in the cycle of the drive signal generated by the timer, and the power consumption is suppressed. In Patent Document 1, the period of the drive signal generated by the timer is changed in accordance with future stability prediction based on the stability of the measured value up to that point. Thereby, when the air conditioning control is stable, the cycle of the drive signal generated by the timer is lengthened, and the power consumption is further suppressed.

JP 2004-355164 A

  However, in Patent Document 1 described above, calculations such as measurement value stability prediction are performed by the wireless sensor, so that the wireless sensor is required to have high processing capability, and power consumption increases and costs increase. . In addition, since the processing capability of the wireless sensor and the information obtained by the wireless sensor are limited, there is a possibility that the prediction is wrong and the air conditioning control is adversely affected.

The present invention has been made to solve such a problem, and the object of the present invention is to increase the processing capacity of the wireless sensor and not adversely affect the air conditioning control. An object of the present invention is to provide a wireless air conditioning control system and an air conditioning controller capable of suppressing power consumption and extending battery life. In addition, the suppression of power consumption according to the present invention is also effective in solving the problem of using self-power generation by illumination light or the like for a wireless sensor whose supply power is weak.

In order to achieve such an object, the present invention makes the wireless communication between the wireless sensor and the air conditioning controller bidirectional, and the wireless sensor generates a drive signal periodically with the circuit main part including the communication part. a timer, each time the drive signal is generated, the main circuit portion and between the operating state for a predetermined time, and means for receiving the information transmitted is sent transmission and air conditioning controller or these measurement data to the air conditioning controller Provided, to the air conditioning controller, an instruction information generating means for generating information for instructing a cycle of the drive signal based on a current execution state of the air conditioning control in the air conditioning control schedule, and a drive signal generated by the instruction information generating means And means for returning information indicating the cycle to the wireless sensor when receiving measurement data from the wireless sensor .

In this invention, whenever a timer produces | generates a drive signal, a radio | wireless sensor makes a circuit main part including a communication part an operation state for a predetermined time, and sends measurement data to an air-conditioning controller. The air conditioning controller receives measurement data from the wireless sensor. At this time, the air conditioning controller generates information indicating the cycle of the drive signal based on the current execution state of the air conditioning control in the schedule of the air conditioning control, and returns the information indicating the cycle of the generated drive signal to the wireless sensor. To do. For example, it is sent every time measurement data from a wireless sensor is received, sent every specified number of times, or sent only when requested by the wireless sensor. Further, as the information for instructing the cycle of the drive signal, the cycle itself is sent, or a predetermined number of operating / pause patterns is sent. The wireless sensor receives information indicating the cycle of the drive signal sent from the air conditioning controller, and sets the cycle of the drive signal of the timer to the cycle indicated by the information. As a result, the timer generates a drive signal at a cycle instructed by the air conditioning controller instead of the previous cycle.

In the present invention, information indicating the cycle of the drive signal to the wireless sensor is generated in the air conditioning controller. For example, based on the current air conditioning control execution status in the air conditioning control schedule, such as a short period during air conditioning operation, a long period when air conditioning is stopped, or a short period during execution of optimal start-up control, the drive signal Information indicating the cycle is generated. In addition, the drive signal may be changed based on the operating status of the monitoring device, such as a short period when the measured value is displayed on the monitoring screen or a short period when a specific monitoring function (for example, high-speed data collection function) is being executed . Information indicating the cycle is generated.

  Also, the abnormality detection means for detecting an abnormality of the air conditioning controller including an abnormality of the wireless line in the wireless sensor, and when the abnormality detection means detects an abnormality, the period of the drive signal is forcibly set to a predetermined long period. And a means may be provided. If such a means is provided in the wireless sensor, the power consumption will exceed the expected value due to continued operation in a short cycle when the air conditioner controller is abnormal (stop / failure, etc.) or when the wireless line is abnormal (communication interruption, etc.). It becomes possible to prevent it from continuing. Air conditioning controller abnormalities, including abnormalities in the wireless line, can be obtained when there is no response that should have been sent to the wireless sensor, or when communication that should have been sent regularly is interrupted Can be detected.

According to the present invention, wireless communication between the wireless sensor and the air conditioning controller is bidirectional, and information indicating the cycle of the drive signal is indicated in the air conditioning controller based on the current execution state of the air conditioning control in the air conditioning control schedule. Since the information indicating the cycle of the drive signal generated by this air conditioning controller is sent back to the wireless sensor when receiving the measurement data from the wireless sensor, the wireless sensor knows the air conditioning controller with high processing capacity. By using the internal information and external information that cannot be obtained to generate information that indicates the cycle of the drive signal, the wireless sensor can be used without increasing the processing capability of the wireless sensor and without adversely affecting the air conditioning control. Power consumption can be suppressed, and the battery life can be extended.

Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing an outline of a wireless air-conditioning control system showing an embodiment of the present invention. In FIG. 6, the same reference numerals as those in FIG. 6 denote the same or equivalent components as those described with reference to FIG. Since claims other than claim 6 can be applied to an independent wireless air conditioning control system including only the wireless sensor 1 and the air conditioning controller 2, the monitoring device 3 and the network 4 are not essential.

  In this embodiment, wireless communication between the wireless sensor 1 and the air conditioning controller 2 is not unidirectional but bidirectional as compared with the conventional wireless air conditioning control system shown in FIG. Some of the functions are different.

  FIG. 2 shows a main part of the wireless sensor (temperature sensor) 1. The wireless sensor 1 is equipped with a replaceable battery 1a such as a dry battery, a timer 1b that constantly receives power from the battery 1a and periodically generates a drive signal S1, and a drive from the timer 1b. A switch 1c that is turned ON / OFF in response to the signal S1 and a transmission / reception antenna 1d are provided.

  In addition, a main circuit portion 1e including a CPU 1A, a ROM 1B, a RAM 1C, interfaces 1D and 1E, and a temperature detector 1F is provided. The battery 1a is connected to the CPU 1A and the interfaces 1D and 1E via a switch 1c. The power from is supplied.

  In the circuit main part 1e, the interface 1D is provided for the temperature detection unit 1F, and constitutes a measurement unit together with the temperature detection unit 1F. The interface 1E is provided for the transmission / reception antenna 1d and constitutes a communication unit together with the transmission / reception antenna 1d.

  The CPU 1A obtains various input information given through the interfaces 1D and 1E, operates in accordance with the program stored in the ROM 1B while accessing the RAM 1C, and constitutes an arithmetic unit.

  The ROM 1B stores a drive signal cycle changing program for changing the cycle of the drive signal S1 generated by the timer 1b in accordance with an instruction from the air conditioning controller 2 as a program unique to the present embodiment.

  The principal part of the air-conditioning controller 2 is shown in FIG. The air conditioning controller 2 operates with a commercial power supply, and includes a CPU 2A, a ROM 2B, a RAM 2C, interfaces 2D and 2E, and a transmission / reception antenna 2F.

  The interface 2D is provided for the transmission / reception antenna 2F and constitutes a sensor communication unit together with the transmission / reception antenna 2F. The interface 2E is connected to the monitoring device 3 via the network 4 and constitutes an upper communication unit.

  The CPU 2A obtains various input information given through the interfaces 2D and 2E, operates in accordance with the program stored in the ROM 2B while accessing the RAM 2C, and constitutes a control arithmetic unit.

  The ROM 2B stores a drive signal cycle generation program that generates information indicating the cycle of the drive signal S1 to the wireless sensor 1 as a program unique to the present embodiment.

[Operation by air conditioning controller]
Hereinafter, the processing operation according to the drive signal period generation program executed by the CPU 2A of the air conditioning controller 2 will be described based on the flowchart shown in FIG. 5 with reference to the time chart shown in FIG.

  In this embodiment, the start time of air conditioning control on weekdays (time TC shown in FIG. 4A) and the stop time (time TD shown in FIG. 4A) are determined in advance as the air conditioning control schedule. It shall be. For example, on weekdays, the start time TC of the air conditioning control is set to 8:00, and the stop time TD is set to 18:00.

  Further, in this embodiment, as the optimum activation control, it is assumed that an advance air conditioning operation is performed so that the target temperature is obtained at the activation time TC of the air conditioning control. In this optimum activation control, a time TA that is a predetermined time before the activation time TC of the air conditioning control is set as the start time of the activation calculation of the optimum activation control (calculation start time of the optimum activation time), and the air conditioning control is started from this time TA It is assumed that the calculation of the optimum start time TB at which the target temperature is obtained at the start time TC is started.

[Generation of Information for Instructing Period of Drive Signal S1 (Generation of Period T)]
Under such a premise, the CPU 2A repeats the processing operation according to the flowchart shown in FIG. 5 at regular intervals. First, in step 101, the CPU 2A checks whether or not the current time is between the calculation start time TA of the optimum start time and the stop time TD of the air conditioning control.

  If the current time is not between the times TA and TD (NO in step 101), the long period T3 is set as the period T (step 105). Here, for example, T3 = 60 sec.

  If the current time is between time TA and TD (YES in step 101), it is determined whether or not the measured temperature is in a stable state in which the measured temperature changes within a predetermined range with respect to the target temperature. Confirm (step 102). Whether the measured temperature is stable or unstable is determined based on the measurement data from the wireless sensor 1 sent so far.

  When the measured temperature is not in a stable state where the measured temperature changes within a specified range with respect to the target temperature (NO in step 102), the short cycle T1 is set as the cycle T (step 103). Here, for example, T1 = 5 sec.

  When the measured temperature is in a stable state that changes within a specified range with respect to the target temperature (YES in step 102), the intermediate period T2 is set as the period T (step 104). Here, for example, T2 = 20 sec.

[Transmission of information indicating cycle of drive signal S1 (transmission of cycle T)]
Then, when the measurement data is received from the wireless sensor 1 (YES in Step 106), the CPU 2A drives the cycle T generated in Steps 101 to 105 together with the reception confirmation signal (ACK) of the measurement data to the wireless sensor 1 as a drive signal. It returns to the wireless sensor 1 as information which instruct | indicates the period of S1 (step 107).

  In FIG. 4B, an arrow indicated by a solid line indicates the transmission timing of measurement data from the wireless sensor 1 to the air conditioning controller 2, and an arrow indicated by a dotted line indicates the ACK and period T of the ACK from the air conditioning controller 2 to the wireless sensor 1. The transmission timing is shown. FIG. 4D shows a change in measured temperature.

  As can be seen from FIGS. 4A and 4B, in this embodiment, when the current time is not between TA and TD, the air conditioning is performed every time measurement data from the wireless sensor 1 is received. A long cycle T3 is sent from the controller 2 to the wireless sensor 1 as information indicating the cycle of the drive signal S1. Further, when the current time is between TA and TD, measurement data from the wireless sensor 1 is received until the measured temperature becomes stable (points t1 to t2 shown in FIG. 4 (d)). Every time, the short cycle T1 is sent from the air conditioning controller 2 to the wireless sensor 1 as information indicating the cycle of the drive signal S1. When the measured temperature becomes stable (points t2 to t3 shown in FIG. 4D), the period of the drive signal S1 is sent from the air conditioning controller 2 to the wireless sensor 1 every time measurement data from the wireless sensor 1 is received. The intermediate period T2 is sent as the instructing information.

  Needless to say, the point t2 in FIG. In addition, if the measured temperature does not change within the specified range determined with respect to the target temperature even between the points t2 to t3, the wireless sensor 1 is sent from the air conditioning controller 2 every time measurement data from the wireless sensor 1 is received. The short cycle T1 is sent as information indicating the cycle of the drive signal S1.

[Operation with wireless sensor]
In the wireless sensor 1, the timer 1b constantly receives power from the battery 1a and periodically generates the drive signal S1. When the timer 1b generates the drive signal S1, the switch 1c is turned on for a predetermined time τ (see FIG. 4C), and the power from the battery 1a is supplied to the CPU 1A and the interfaces 1D and 1E. As a result, the circuit main unit 1e is in an operating state for a predetermined time τ, and the temperature detected by the temperature detection unit 1F is transmitted to the air conditioning controller 2 as measurement data (measurement temperature).

  It is assumed that the current time is within the range from the air conditioning control stop time TD to the calculation start time TA of the next day's optimum start time. That is, it is assumed that the current time is not between the times TA and TD. In this case, when the wireless sensor 1 transmits measurement data to the air conditioning controller 2, the air conditioning controller 2 that has received the measurement data returns a long period T3 to the wireless sensor 1 as information indicating the period of the drive signal S1 together with ACK. The CPU 1A of the wireless sensor 1 receives the long period T3 from the air conditioning controller 2 and sets it in the timer 1b. Thereby, the timer 1b generates the drive signal S1 with the long cycle T3.

  When the current time has passed the calculation start time TA of the optimum activation time, the air conditioning controller 2 that has received the measurement data from the wireless sensor 1 uses the short cycle T1 as information indicating the cycle of the drive signal S1 together with ACK. Return to The CPU 1A of the wireless sensor 1 receives the short cycle T1 from the air conditioning controller 2 and sets it in the timer 1b. Thus, the timer 1b generates the drive signal S1 with the short cycle T1 instructed from the air conditioning controller 2 instead of the long cycle T3 so far.

  When the current time has passed the calculation start time TA of the optimum activation time and reaches the optimum activation time TB started at the time TA, the air conditioning operation is started so that the target temperature is obtained at the activation time TC of the air conditioning control. The By this air conditioning operation, the air conditioning control is performed ahead of schedule, and the measured temperature approaches the target temperature.

  When the measured temperature is in a stable state where the measured temperature changes within a predetermined range determined with respect to the target temperature (point t2 shown in FIG. 4 (d)), the air conditioning controller 2 that has received the measurement data from the wireless sensor 1 The medium period T2 is returned to the wireless sensor 1 as information indicating the period of the drive signal S1 together with ACK. The CPU 1A of the wireless sensor 1 receives the medium period T2 from the air conditioning controller 2 and sets it in the timer 1b. Thereby, the timer 1b generates the drive signal S1 at the medium cycle T2 instructed by the air conditioning controller 2 instead of the short cycle T1 so far.

  In this way, in the present embodiment, when the current time is not between the times TA and TD, the wireless sensor 1 repeatedly operates and pauses the circuit main unit 1e including the communication unit in the long cycle T3. If the current time is between time TA and TD, the wireless sensor 1 has a short time depending on whether or not the measured temperature is in a stable state where the measured temperature changes within a specified range with respect to the target temperature. The operation and pause of the circuit main unit 1e including the communication unit are repeated in the cycle T1 or the intermediate cycle T2. Thereby, the power consumption in the wireless sensor 1 is suppressed and the battery life is extended.

  In the present embodiment, the air conditioning controller 2 generates the cycle T as information indicating the cycle of the drive signal S1, and transmits the cycle T from the air conditioning controller 2 to the wireless sensor 1. Therefore, the wireless sensor 1 does not have to perform calculation such as prediction of the stability of the measured value, and the processing capability of the wireless sensor 1 need not be increased. Therefore, a low-cost wireless sensor 1 can be used.

  In the present embodiment, the air conditioning controller 2 has a processing capability much higher than that of the wireless sensor 1, and the air conditioning controller 2 having the high processing capability generates a cycle T as information indicating the cycle of the drive signal S1. Therefore, even if the calculation amount is large, the cost is not increased. In addition, as information that the wireless sensor 1 cannot know, “air conditioning control schedule” and “information regarding optimum drive control” are used, and these information and “measured temperature stability / unstable information” are combined to drive signals. Since the period T of S1 is generated, there is no possibility of making a mistake in prediction and there is no possibility of adversely affecting the air conditioning control.

  In the above-described embodiment, the switch 1c is turned on by the drive signal S1 generated by the timer 1b and the power from the battery 1a is supplied to the CPU 1A and the interfaces 1D and 1E. However, the drive generated by the timer 1b is used. The CPU 1A may be woken up by the signal S1, and power may be supplied from the battery 1a to the interface 1D or 1E under the control of the CPU 1A. As the timer 1b, a sleep control timer built in the CPU 1A may be used.

  In the above-described embodiment, every time measurement data is received from the wireless sensor 1, the cycle T is sent from the air conditioning controller 2 as information indicating the cycle of the drive signal S1 together with ACK. It may be sent or sent only when requested by the wireless sensor 1. Further, when the period T is changed in the air conditioning controller 2, the changed period T may be sent only when the measurement data is subsequently received from the wireless sensor 1. By doing in this way, it becomes possible to shorten the average operation time of the wireless sensor 1, and to further suppress the power consumption in the wireless sensor 1.

  In the above-described embodiment, the period T is sent from the air conditioning controller 2 to the wireless sensor 1 as information indicating the period of the drive signal S1, but a predetermined number of operating / pause patterns is sent. It may be.

Further, in the above-described embodiment, information indicating the cycle of the drive signal S1 is generated by combining the “air conditioning control schedule”, “information regarding optimum start-up control”, and “information on stability / instability of measured temperature”. However, it is not limited to such a combination. For example, the following (1) to (2), a method in a cycle of the drive signal S1, such as (5) may generate information indicating the (intermittent operation period), "air-conditioning control Scheduling" ( 3), (4), (6), (7), and (8) may be generated in combination.

(1) Judgment based on operation / stop of air conditioning A short cycle during air conditioning operation and a long cycle during air conditioning stop.
(2) Judgment based on air-conditioning operation / stop + schedule operation setting. If the air conditioning is stopped and the intermittent operation cycle time is less than the scheduled operation start, the cycle is short. If the air conditioning is stopped and the intermittent operation cycle time is longer than the scheduled operation start, the cycle is long. Note that the time until switching to a short cycle may be specified.

(3) Judgment based on the speed and frequency of measurement value change The shorter the cycle, the more rapidly or frequently the measurement value changes.
(4) Judgment based on speed / frequency of measurement value change + change in control target value In addition to the above (4), a short period is set for a specified time from the change in control target value.
(5) Judgment based on the execution status of a specific control function (example: optimal startup control)
During air conditioning operation and when optimal start-up control is not being executed, the cycle is set to the middle period. If it is less than or equal to the intermittent operation cycle time until the start of execution of optimal start-up control, the cycle is short. A short cycle is used when the optimal startup control is being executed (during startup calculation or result evaluation calculation). If it is longer than the intermittent operation cycle time until the start of execution of optimal start-up control, the cycle is long. Note that the time until switching to a short cycle may be specified.

(6) Judgment based on instructions from the supervisor Operate at intervals specified by the supervisor. A cycle designation notification is sent at regular intervals, and when the notification stops, the cycle is returned to the original cycle.
(7) Judgment from the operation of the monitor The period when the monitor is displaying the measured value (while displaying the measured value on the monitoring screen) is a short cycle. When the monitor is not displaying the measured value (when the measured value is not being displayed on the monitoring screen), the long cycle is set.
(8) Judgment based on the execution status of a specific monitoring function For example, a specific monitoring function is a high-speed data collection function, a short cycle is set during execution of the high-speed data collection function, and a long cycle is set during non-execution of the high-speed data collection function. .

[Abnormal processing]
Further, although not described in the above-described embodiment, a processing program at the time of abnormality is stored in the ROM 1B of the wireless sensor 1. The CPU 1A detects an abnormality of the air conditioning controller 2 including an abnormality of the wireless line according to the processing program at the time of abnormality. When this abnormality is detected, the cycle of the drive signal S1 is forcibly set to a predetermined long cycle. That is, a predetermined long cycle is set in the timer 1b.

  By doing so, when the air conditioning controller 2 is abnormal (stop / failure, etc.) or when the wireless line is abnormal (communication is interrupted, etc.), it will continue to consume more power than expected due to continued operation in a short cycle. It becomes possible to prevent. In the case of an abnormality in the air conditioning controller 2 including an abnormality in the wireless line, when a response that should be originally intended for transmission from the wireless sensor 1 cannot be obtained, communication that should normally be sent periodically is interrupted. In some cases, it can be detected.

  In the above-described embodiment, the wireless sensor 1 is a temperature sensor, but a humidity sensor, a sensor / setting device, or the like is also used to send information indicating the cycle of the drive signal S1 from the air conditioning controller 2. It is possible to reduce power consumption and extend battery life.
