Description

  The present invention relates to a measuring apparatus configured to be able to measure electrical parameters of a measurement object.

  As this type of measuring device, an automobile waveform observation device (hereinafter also simply referred to as “observation device”) is disclosed in Japanese Patent Application Laid-Open No. 8-35914. This observation device measures parameters for each of the five items of “air flow meter”, “crank angle sensor”, “water temperature sensor”, “injector drive”, and “ignition instruction” while mounted on the vehicle to be observed. The measurement result can be displayed on the monitor. In addition, this observation apparatus is configured to store an appropriate value for the above five items in advance so that an alarm can be issued when a signal deviating from the appropriate value is measured.

JP-A-8-35914 (pages 3-6, FIGS. 1-8)

  However, the conventional observation apparatus has the following problems. That is, the conventional observation apparatus employs a configuration in which measurement processing for five items is always executed and the measurement result is displayed on the monitor, and an alarm is issued when a signal deviating from an appropriate value is measured. Yes. In this case, for example, when performing measurement processing for various items for the purpose of fault diagnosis of a vehicle in which some trouble occurs during traveling, measurement processing and measurement results for each item when the target vehicle is stopped No display processing is required. However, the conventional observation apparatus employs a configuration that always executes measurement processing and measurement result display processing for five items regardless of the state of the target vehicle. In applications, there is a problem that power is consumed by performing unnecessary measurement processing and unnecessary display processing.

  In addition, as an application of this type of device, for example, measurement processing for the purpose of fault diagnosis of a vehicle in which some trouble occurs when a predetermined altitude (altitude) is exceeded or below a predetermined altitude (altitude) Is mentioned. However, since the conventional observation apparatus cannot obtain information that can specify the altitude of the target vehicle, the measurement processing for each item and the measurement result display processing are executed even at an altitude at which no malfunction occurs. Need arises. For this reason, there is a problem that power is consumed due to execution of unnecessary measurement processing and unnecessary display processing even in applications intended for such failure diagnosis.

  Furthermore, the use of this type of device includes not only measurement processing and measurement result display processing for each item for fault diagnosis, but also measurement processing and display processing for each item during circuit driving, for example. It is done. In this case, for example, there is a case where it is desired to execute the measurement process and the display process for each item only in an arbitrary section of one round. However, in the conventional observation apparatus, since it is not possible to obtain information that can specify which section of the course the target vehicle is traveling on, the measurement processing and display for each item are also performed outside the desired section. It becomes necessary to execute processing. For this reason, even in such applications, there is a problem in that power is consumed by executing unnecessary measurement processing and unnecessary display processing.

  On the other hand, in the various applications described above, when an attempt is made to record the measurement result of the measurement process in a recording unit such as a memory, a conventional observation apparatus configured to execute the measurement process for each item regardless of the state of the target vehicle Then, not only power is consumed by the process of recording unnecessary measurement results, but also the amount of measurement result data recorded in the recording unit increases in a short time. For this reason, the recordable capacity of the recording unit is reduced in a short time. Therefore, when a configuration for recording measurement results is added to the conventional observation apparatus, there arises a problem that necessary measurement results cannot be recorded for a long time.

  The present invention has been made in view of such problems, and a main object of the present invention is to provide a measurement apparatus that can acquire necessary measurement results while reducing power consumption.

In addition, “predetermined speed” includes “speed within a specified range centered on the specified speed”, “speed other than the specified speed”, and “other than the specified range centered on the specified speed”. This includes “speed of”. Furthermore, “predetermined orientation” includes “an orientation within a prescribed range centered on a prescribed orientation”, “an orientation other than the prescribed orientation” and “other than a prescribed range centered on a prescribed orientation” This includes “direction of”.

Since unnecessary measurement results are not recorded in the recording unit, it is possible to avoid the situation in which the valuable recordable area of the recording unit is occupied by unnecessary measurement results, and the necessary measurement results can be obtained with a small-capacity recording unit. It can be recorded and acquired for a long time. Further, power consumption can be reduced by the amount of power required to record measurement results that do not need to be recorded.

  According to the measuring apparatus of claim 2, when the positioning information that satisfies the pre-defined conditions is output from the GPS receiver, the control unit controls the measuring unit to Measurement is performed by executing at least one of a measurement start process for starting a measurement process for measuring a parameter and a measurement stop process for controlling the measurement unit to stop the measurement process and associated with a predetermined condition.

The measurement result is acquired by executing at least one of the measurement result display start process for starting the display of the result and the measurement result display stop process for stopping the display of the measurement result, which is associated with a predetermined condition. Since the display process is not executed when it is not necessary to perform the measurement, it is possible to display and acquire a necessary measurement result while reducing power consumption.

  Furthermore, according to the measuring apparatus of claim 4, the first condition that the control unit is located at a predetermined position, and the second condition that the controller is moving at a predetermined speed. Further, by setting at least one of the third conditions that the user is moving in a predetermined direction as a predetermined condition, it is possible to perform detailed condition setting according to a desired application. it can. For this reason, in the measuring apparatus configured to execute the recording start process and the recording stop process, the necessary measurement result can be recorded for a longer time, and the electric power generated by recording the measurement result that does not need to be recorded can be recorded. Consumption can be avoided and power consumption can be further reduced. Further, in the measurement apparatus configured to execute the measurement start process and the measurement stop process, it is possible to avoid power consumption due to the measurement process that does not need to be performed, and to further reduce the power consumption. Furthermore, in the measurement apparatus configured to execute the measurement result display start process and the measurement result display stop process, it is possible to further reduce the power consumption by avoiding the power consumption due to the measurement result display process that does not need to be performed. Can do.

  In addition, according to the measurement device of the fifth aspect, since the GPS receiver includes at least the receiver main body, the receiver main body is separated from the installation of the measurement device, unlike the measurement device in which these are separately provided. The operation of installing the unit becomes unnecessary, and the measurement process and the measurement result recording process can be started quickly and easily by simply installing the measurement device.

1 is a block diagram showing a configuration of a measuring device 1. FIG. 10 is a flowchart of a measurement result recording process 10.

  Hereinafter, embodiments of a measuring apparatus will be described with reference to the accompanying drawings.

  1 is an in-vehicle data recorder that is an example of a “measuring device”, and includes a GPS receiver 2, a measuring unit 3, an operating unit 4, a display unit 5, a recording unit 6, and a control unit 7. It is prepared for. In this case, the GPS receiver 2 includes, as an example, a receiver main body and a receiving antenna connected to the receiver main body via a cable (both not shown). Further, in this example, the receiver main body is disposed (built in) in the housing of the measuring apparatus 1 together with each of the above-described components 3 to 7, and the receiving antenna is fixed to an arbitrary part of the measurement target automobile. It is configured to be able to. The GPS receiver 2 uses the positioning information D1 by specifying the position, moving speed, moving direction and the like of the GPS receiver 2 (receiving antenna) based on the GPS signal S1 received by the processing unit in the receiver main body via the receiving antenna. Output as. Note that the positioning information D1 includes, as an example, information such as the current time, information about the satellite being supplemented, latitude, lightness, altitude (altitude: above sea level), direction (traveling direction), and speed. .

On the other hand, the measurement unit 3 includes, as an example, a connection connector 3a that can be connected to an automobile failure diagnosis connector, and performs measurement processing on various measurement target signals S2 input through the connection connector 3a. Then, measurement result information D2 indicating the measurement result is output to the control unit 7. In this case, in this example, as an example, in a state where the measuring apparatus 1 is powered on, the measurement unit 3 performs “sensor signal from crank angle sensor” via the failure diagnosis connector and the connection connector 3a. , “Injector control signal”, “Sensor signal from water temperature sensor”, “Sensor signal from air flow meter, intake pressure sensor and supercharging pressure sensor”, “Sensor signal from throttle sensor”, “O ₂ sensor Various signals such as “sensor signal” and “sensor signal from the vehicle speed sensor” are acquired as the measurement target signal S2, and the current value, voltage value and phase of these signals, and the resistance of each sensor based on these signals Measurement processing such as a value (an example of “electrical parameter”) is continuously executed to output measurement result information D2.

  As an example, the operation unit 4 includes a touch panel configured integrally with the display unit 5 and operation switches for performing various operations, and outputs operation signals corresponding to these operations to the control unit 7. The display unit 5 includes, for example, a liquid crystal display. The display unit 5 includes a “setting screen” for setting the operating conditions of the measuring device 1 according to the control of the control unit 7, and the measurement result (as an example) , “Numerical value, symbol, graph, waveform, etc.)” is displayed (not shown). It is also possible to adopt a configuration in which the measurement results and the like are displayed on a “display unit” as an external device without providing the display unit 5. As an example, the recording unit 6 includes a removable memory and a memory mounting unit to which the removable memory can be mounted (both not shown), and a measurement result output from the measuring unit 3 according to the control of the control unit 7 Information D2 and the like are recorded.

  The control unit 7 comprehensively controls the measuring device 1. Specifically, the control unit 7 controls the measurement unit 3 to execute the measurement process for each measurement target signal S2 and various information based on the measurement result information D2 output from the measurement unit 3. Is displayed on the display unit 5. Further, the control unit 7 executes the measurement result recording process 10 shown in FIG. 2, analyzes the positioning information D1 output from the GPS receiver 2, and determines that the positioning information D1 that satisfies various conditions described later is output. Recording start processing for starting recording of the measurement result information D2 from the measurement unit 3 to the recording unit 6 (removable memory), and recording stop processing for stopping recording of the measurement result information D2 to the recording unit 6 Run.

  In the measurement apparatus 1 of this example, the control unit 7 analyzes the positioning information D1, and determines that the positioning information D1 that satisfies one or more conditions selected from the following conditions is output. Sometimes, a configuration is employed in which one of “recording start processing” and “recording stop processing” associated with the condition is executed. Specifically, in the measurement apparatus 1 of the present example, the condition (“first condition”) for the “position” of the GPS receiver 2 (ie, the target vehicle), and “movement” of the GPS receiver 2 (ie, the target vehicle). From the condition regarding “speed” (“second condition”) and the condition regarding “movement direction (direction)” of the GPS receiver 2 (that is, the target vehicle) (“third condition”), “recording start” “Arbitrary one condition”, “AND condition”, or “OR condition” associated with “process” and “recording stop process” can be arbitrarily selected.

  More specifically, in the measuring apparatus 1, as the above “first condition”, the condition “located at a specified latitude / longitude”, “located at a specified altitude” The condition that “is located within the prescribed range centered on the specified latitude and longitude”, the condition that “is located within the specified range centered on the specified altitude”, The condition is “located outside the specified latitude / longitude”, the condition “positioned outside the specified altitude”, and the position “outside the specified range centered on the specified latitude / longitude” It is configured such that an arbitrary condition can be selected from among the condition “I am doing” and the condition “I am located outside the specified range centered on the specified altitude”.

  Further, in the measuring apparatus 1, as the above “second condition”, the condition “when moving at a specified speed”, “moving at a speed within a specified range centered on the specified speed”. `` When moving '', `` When moving at a speed other than the specified speed '', and `` When moving at a speed outside the specified range centered on the specified speed '' Any condition of the above conditions can be selected. Further, in the measuring apparatus 1, as the above “third condition”, the condition “when moving to a specified direction”, “moving to a direction within a specified range centered on the specified direction” "When moving", "When moving to an orientation other than the specified orientation", and "When moving to an orientation other than the specified range centered on the specified orientation" Any condition of the above conditions can be selected.

  When using the measuring apparatus 1, as an example, the measuring apparatus 1 is installed on a dashboard of a vehicle as a measurement object. Next, the receiving antenna of the GPS receiver 2 is fixed to the roof, and the failure diagnosis connector and the connection connector 3a are connected to each other using a harness (not shown). Subsequently, by operating the operation unit 4, a “condition” (hereinafter also referred to as “start condition”) for executing the “recording start process” and a “condition” (hereinafter, referred to as “recording stop process”). Each of them is also set as “stop condition”. In this case, as an example, the condition “when moving at a speed exceeding 30 km / h” is set as a start condition, and the condition “when moving at a speed lower than 20 km / h” is set. Is set as a stop condition.

  In order to facilitate understanding of the operation principle of the measuring apparatus 1, one condition is set as a start condition (corresponding to “recording start process”), and another one condition is set as a stop condition ( An example of “corresponding to“ recording stop processing ”” will be described. However, a plurality of conditions (for example, “when moving at a speed exceeding 30 km / h”) as a start condition and a stop condition, and “altitude above 300 m” It is also possible to set the condition “when it is located”.

  In this case, for example, the “measurement process” is performed on the sensor signal output from the vehicle speed sensor in the measurement target vehicle, and the “measurement” for each item is performed only when the target vehicle is running. It is also conceivable to adopt a configuration for executing “processing”. However, when such a configuration is adopted, even when “measurement processing” regarding “speed” and recording of measurement result information D2 regarding “speed” are not necessary, “measurement processing” In order to specify the timing for starting / stopping recording of the measurement result information D2, one of the measurement units (measurement channels) of the measurement unit 3 is occupied for the measurement of “speed”.

  On the other hand, as will be described later, in the measurement apparatus 1 configured to execute the “recording start process” and the “recording stop process” in accordance with the positioning information D1 from the GPS receiver 2, One of the above is prevented from being occupied for the measurement of “speed” for the purpose of executing “recording start processing” and “recording stop processing”. As a result, when it is not necessary to record “measurement processing” regarding “speed” or measurement result information D2 regarding “speed”, the measurement unit of the measurement unit 3 is assigned to measurement of measurement items other than “speed”. Is possible.

  Next, after operating a start switch (not shown), the automobile is driven. At this time, the GPS receiver 2 receives the GPS signal S1 and analyzes the received GPS signal S1, thereby calculating the position, moving speed, and moving direction of the GPS receiver 2 (receiving antenna), and positioning information. D1 is output. In addition, since the principle of positioning by the GPS receiver 2 is well-known, detailed description is abbreviate | omitted. On the other hand, the control unit 7 controls the measurement unit 3 according to the operation of the start switch to start the “measurement process” for the measurement target signal S2. At this time, the measurement target signal S2 is input to the measurement unit 3 via the failure diagnosis connector, the dedicated harness, and the connection connector 3a, and accordingly, the measurement unit 3 performs electrical measurement on each measurement target signal S2. The parameter is measured and measurement result information D2 is output to the control unit 7. Further, based on the measurement result information D2 output from the measurement unit 3, the control unit 7 includes, for example, “speed”, “engine speed”, “water temperature”, and “intake pressure (or boost pressure)”. Such information is displayed on the display unit 5 (not shown).

  Further, the control unit 7 starts the measurement result recording process 10 shown in FIG. 2 according to the operation of the start switch. In the measurement result recording process 10, the control unit 7 first determines whether or not the positioning information D1 that satisfies the above start condition is output (step 11). At this time, when it is determined that the control unit 7 is moving at a speed of 30 km / h or less, the control unit 7 waits until the speed exceeds 30 km / h and is moving at a speed exceeding 30 km / h. When the determination is made, recording of the measurement result information D2 output from the measurement unit 3 to the recording unit 6 is started (an example of “recording start process”: step 12). Thereby, the measurement result information D2 of the “measurement process” executed by the measurement unit 3 at a speed exceeding 30 km / h is sequentially recorded in the recording unit 6.

  On the other hand, after executing the “recording start process”, the control unit 7 determines whether or not the positioning information D1 that satisfies the stop condition is output (step 13). At this time, when the control unit 7 determines that the vehicle is moving at a speed of 20 km / h or more, the control unit 7 continuously records the measurement result information D2 in the recording unit 6 until the speed becomes lower than 20 km / h. In addition, when it is determined that the vehicle is moving at a speed lower than 20 km / h, the recording of the measurement result information D2 output from the measuring unit 3 to the recording unit 6 is stopped (an example of “recording stop process”: Step 14). Thereafter, when the positioning information D1 that satisfies the start condition is output (step 11), the control unit 7 executes “recording start processing” (step 12), and the positioning information D1 that satisfies the stop condition is output. (Step 13), the “recording stop process” is executed (Step 14). Thus, the recording of the measurement result information D2 that needs to be acquired by the user to the recording unit 6 is completed.

  As described above, according to the measurement apparatus 1, the control unit 7 controls the recording unit 6 when the positioning information D1 satisfying the “predetermined condition” is output from the GPS receiver 2, and the measurement unit 3. Corresponding to “predetermined condition” of “recording start process” for starting recording of measurement result information D2 of “measurement process” 3 and “recording stop process” for stopping recording of measurement result information D2 By executing at least one of these, unnecessary measurement result information D2 is not recorded in the recording unit 6 in a state where the measurement result information D2 does not need to be recorded. It is possible to avoid the situation where the 6 precious recordable areas are occupied and to record and acquire the necessary measurement result information D2 for a long time by the recording unit 6 with a small capacity. Further, power consumption can be reduced by the amount of power required to record measurement result information D2 that does not need to be acquired.

  Moreover, according to this measuring apparatus 1, the control part 7 is "it is located in the position prescribed | regulated previously." "The 1st condition" and "it is moving at the speed prescribed | regulated previously." Desired by setting at least one of the “second condition” and the “third condition” “moving in a predetermined direction” as the “predetermined condition” Since detailed conditions can be set according to the application, necessary measurement result information D2 can be recorded for a longer time, and power consumption by recording measurement result information D2 that does not need to be recorded. Can be avoided and the power consumption can be further reduced.

  Furthermore, according to the measurement device 1, the “receiver body” in the GPS receiver 2 is built in, so that it is different from the “measurement device” in which the GPS receiver 2 is separately provided, which is different from the installation of the “measurement device”. The operation of installing the “receiver main body” is not required, and the measurement process and the recording process of the measurement result information D2 can be started quickly and easily by simply installing the “measurement device”.

  The “measuring device” is not limited to the configuration of the measuring device 1 described above. For example, the measurement apparatus 1 configured to execute both the “recording start process” and the “recording stop process” has been described, but a configuration that executes only one of the “recording start process” and the “recording stop process” is adopted. can do. Specifically, a configuration in which “recording start processing” is performed according to conditions unrelated to the positioning information D1 (for example, recording is started at a predetermined time), or measurement result information D2 is manually recorded. A starting configuration can be employed. In addition, a configuration for executing “recording stop processing” according to a condition unrelated to the positioning information D1 (for example, the recording is stopped when a predetermined time elapses), or manually recording the measurement result information D2 A configuration for stopping can be employed. Even when such a configuration is adopted, unnecessary recording of the measurement result information D2 can be sufficiently reduced.

  Further, in the configuration in which either “recording start processing” or “recording stop processing” is executed according to the positioning information D1, the measurement device 1 having a configuration in which “measurement processing” by the measurement unit 3 is continuously executed is taken as an example. However, the “measurement start process” and the “recording start process”, the “measurement stop process”, and the “recording stop process” are performed according to the positioning information D1 without continuously executing the “measurement process”. ”(A configuration in which recording of measurement result information D2 is started / stopped in conjunction with the start / stop of“ measurement processing ”) may be employed.

  Furthermore, although the example applied to the data recorder (measurement result recording device) has been described, for example, information (measurement result) based on the measurement result information D2 is displayed on the display unit 5 without recording the measurement result information D2. In the information display apparatus, a configuration in which the start / stop of the measurement process is controlled according to the measurement result information D2 from the GPS receiver 2 may be employed. In addition, when applying this invention to an information display apparatus, the recording part 6 in said measuring apparatus 1 is unnecessary as an example, and it is the same as that of the measuring apparatus 1 about the other components 2-5, and 7. To do. In this case, since the content of the “measurement process” by the measurement unit 3 in such a configuration is the same as that of the measurement apparatus 1 described above, the description thereof is omitted. The “measurement start condition” for starting the “measurement process” and the “measurement stop condition” for stopping the “measurement process” are the same as the “recording start condition” and the “recording stop condition” in the measurement apparatus 1 described above. Therefore, the description is omitted.

  When the present invention is applied to the information display device, the control unit 7 controls the measurement unit 3 when the positioning information D1 satisfying the “predetermined condition” is output from the GPS receiver 2, and the measurement object “Predetermined conditions” of “measurement start process” for starting “measurement process” for measuring electrical parameters and “measurement stop process” for controlling measurement unit 3 to stop “measurement process” ”Is executed. Therefore, by adopting such a configuration, “measurement processing” is not executed when there is no need to obtain measurement results, so that necessary measurement results can be obtained while reducing power consumption. Can do.

  In addition, the control unit 7 is “a first condition” that “is located at a predetermined position”, “a second condition” that “moves at a predetermined speed”, and At least one of the “third conditions” “moving in a predetermined direction” is associated with the “predetermined condition” as a “predetermined condition”. By executing one of them, detailed conditions can be set according to the desired application, thus avoiding power consumption due to “measurement processing” that does not need to be performed and further reducing power consumption. Can do.

  In this case, not only a configuration that executes both the “measurement start process” and the “measurement stop process” but also a configuration that executes only one of the “measurement start process” and the “measurement stop process” can be adopted. . Specifically, a configuration in which “measurement start processing” is executed according to conditions unrelated to the positioning information D1 (for example, the measurement processing is started at a predetermined time), or a measurement processing is manually started. Can be adopted. In addition, a configuration that executes “measurement stop processing” according to conditions unrelated to the positioning information D1 (for example, the measurement processing is stopped when a predetermined time elapses), or the measurement processing is manually stopped. It is possible to adopt a configuration to Even when such a configuration is adopted, it is possible to sufficiently reduce the execution of unnecessary measurement processing.

  Further, the measurement result of the measurement process by the measurement unit 3 is not continuously displayed, and at least one of “measurement result display start process” and “measurement result display stop process” is executed according to the positioning information D1. A configuration (a configuration in which display of measurement results is started / stopped according to the positioning information D1) can be employed. The conditions for starting the display of the measurement results and the conditions for stopping the display of the measurement results are the same as the “recording start conditions” and the “recording stop conditions” in the measurement apparatus 1 described above, and thus description thereof is omitted. By adopting such a configuration, measurement result display processing is not executed when there is no need to obtain measurement results, so that necessary measurement results are displayed and acquired while reducing power consumption. Can be made. In this case, when the present invention is applied to the measurement apparatus having such a configuration, either the configuration in which the measurement result information D2 is recorded or the configuration in which the measurement result information D2 is not recorded is adopted in the same manner as the measurement device 1 described above. May be. Furthermore, the measurement process and the measurement result recording process can be configured to start / stop in conjunction with the display of the measurement result. For example, the measurement process is continuously performed regardless of the display of the measurement result. A configuration for executing processing and recording processing may be employed.

  Further, according to the positioning information D1 from the GPS receiver 2, “recording start process”, “recording stop process”, “measurement start process”, “measurement stop process”, “measurement result display start process” and “measurement result display stop” The configuration for executing the “processing” has been described as an example, but an arbitrary condition related to the positioning information D1 and a condition “when the measurement result of the measurement target signal S2 satisfies a predetermined condition” When both of the above are satisfied, at least one of “recording start process”, “recording stop process”, “measurement stop process”, “measurement result display start process” and “measurement result display stop process” is executed It is also possible to adopt a configuration that does this. Specifically, as an example, when both the condition “when moving at a speed exceeding 80 km / h” and the condition “when the engine speed exceeds 3000 rpm” are satisfied “Recording start process” (or “measurement result display start process”) is executed, and the condition “when it is lower than 20 km / h” and “when the engine speed is lower than 1500 rpm” When both of the conditions are satisfied, the “recording stop process” (or “measurement stop process” or “measurement result display stop process”) may be executed.

  Moreover, although the connection connector 3a that can be connected to the failure diagnosis connector has been described as an example of the configuration for performing measurement processing on various signals input through both connectors, the sensor of the target vehicle or the like has been described. Alternatively, a configuration in which the measurement unit 3 is directly connected, or a configuration in which a signal dedicated to the measurement device is attached to the target vehicle or the like to obtain a signal may be employed. Furthermore, the use of the “measuring device” (“measurement object”) is not limited to the measurement of electrical parameters for automobiles (four-wheeled vehicles), but various vehicles such as two-wheeled vehicles and trains, aircraft and ships, etc. The electrical parameters of various measuring devices that are moved together with various measuring objects can be measured.

  In addition, the measurement apparatus 1 in which the receiver main body configured separately from the reception antenna is incorporated (that is, integrated) in the measurement apparatus together with each of the components 3 to 7 has been described as an example. A configuration in which the entire “GPS receiver” is built in each of the components 3 to 7 can be adopted, or a configuration in which the positioning information D1 is obtained by connecting the “GPS receiver” as an external device to the control unit 7 is adopted. It can also be done (both not shown). Even when such a configuration is adopted, the same effects as those of the measuring apparatus 1 described above can be obtained.
