The stop event is an event created at the time of stopping and at the time of starting traveling, respectively. This event also collects various data, and the data to be collected depends on the settings. In the one-minute time series event, a vehicle state, a work state, and an external input channel state are collected. In the external input channel state, external input digital channels 1-7, external input analog channels 8-10
It is possible to set whether to collect data individually or not for each channel. However, if the external input digital channels 1 to 7 are set to count in the setting, the state is not measured. Therefore, the data becomes 0.

The external input digital state is a high level state when data is 1, and a low level state (0 V) when data is 0. This data adopts the state with the largest ratio in one minute for each channel, and describes the high level and the low level. In the work state, the work state by key input of the handy key is recorded. This data records the state with the highest rate in one minute.
In the vehicle state, whether the vehicle is running, stopped, or idling is recorded. Also, the states of the A and B buttons are recorded.
This data records the state where the ratio in one minute is the largest.

(3) Storage When a storage request is transmitted from the main board, all the measurements (information such as mileage / running time) are completed at that time, and after the storage event is created, the storage is being performed. During this processing, the key input of the handy key is invalidated. In this case, each data collection is stopped. If there is a handy numeric key, the receipt processing of the handy numeric key is performed. If state saving is set in the settings, save the state. Create an input event. If there is a one-minute time series event creation, an event is created. Return during storage.

It is effective only when the abnormal value setting is set in the function table in the abnormal value setting. The settable range is the temperature: -40 to 40 ° C, 0.1 ° C,
In the case of humidity: 0 to 100%.

External input 8 to 10 ch range inside / outside can be set for each channel, and is used as an abnormal alarm set value for external input channels 8, 9, and 10. Therefore, when the function of the corresponding channel is not set to the abnormality alarm in the function table, the channel is invalidated. If it is within the range set by the upper limit value and the lower limit value of the analog channel, it is determined to be an abnormal value.

If the upper limit value ≦ the analog channel input value ≧ the lower limit value is outside the range set by the upper limit value and the lower limit value of the analog channel, it is regarded as an abnormal value.

Upper limit value ≧ Analog channel input value ≦ Lower limit value Analog channel input value When the upper limit value and the lower limit value of the analog channel are set, the abnormal value setting is invalidated.

Event creation conditions (unit: time / second speed / km / h) at the time of trigger setting of external input channels 1 to 7 can be set for each channel. In this setting, external input channels 1 to 7 are set as triggers, and The conditions are "Create an event after the set time elapses after the trigger occurs" or "Create an event when the set speed state occurs after the trigger occurs" or "Create an event when the set speed state occurs after the trigger occurs". Only works if

The settable range is from 0 to 127 (seconds), and an event is created after a trigger has occurred and a set time has elapsed. Creates an event at the set speed after the trigger occurs.
(For the speed, check the status with the raw data every 0.5 seconds of the speed calculation.) 0 to 100 (km / h) Abnormal when the value of the external input channels 8 to 10 is higher than the set abnormal value. After performing the alarm processing, a time interval at which the abnormality alarm is performed again is set. 1 from 00 to 127 (minutes)
It can be set in minutes.

If the values of the external input channels 8 to 10 have a level equal to or higher than the set abnormal value and the time level equal to or longer than the timer value continues, an abnormal alarm is issued. 00 to 127 (seconds)
Up to one minute can be set.

(5) In the function table setting shown in FIG. 5, (a) the input setting of the function key F can be set for each key, and it is possible to input the operation state, the operation state + the ten-key input, the ten-key input, and the event input. This is the setting to be used. In function setting 1, ten-key input is assigned to the F key. Assign work state + numeric keypad input to F key. F
Assign event data collection to a key. One of the three functions is selected.

In the function setting 2, when the working state is released, the vehicle automatically enters the actual vehicle state. The work state is released when the continuous running time satisfies the automatic release setting. During the work state, the buzzer sounds when a running pulse is input. One of the three functions is selected.

(B) External input function setting Function settings of the external input channels 1 to 7 are set for each channel. Function selection selects one from the following functions.

Count not collected (create an event when the count value reaches the count value set in the system. If there is an abnormal value setting, an abnormal alarm is generated.) Count for each rising signal. For each falling signal. To the counting time (when this time value becomes the time value set in the system,
Create an event. If there is an abnormal value setting, an abnormal alarm is issued. ) Collect the time from rising to falling Collect the time from falling to rising Trigger Create an event for each rising signal Create an event for each falling signal Create an event for each change in the signal , Set whether to use the function of the external input digital as the setting for abnormal alarm.
Event data can be created even when used as a setting for an abnormal alarm. The reaction speed enables a pulse count or trigger with a pulse width of 100 ms or more. A pulse count or a trigger with a pulse width of 1 s or more is made valid. One of the two types is selected. Only works when count or trigger is selected in function selection.

The reaction time ignores pulses within a certain time. Functions only when count and trigger are selected in function selection. The setting range is, for example, 0.1 to 12.7.
Seconds can be set in 0.1 second increments. In the case of a trigger, one of the following three conditions is selected. It works only when trigger is selected in function selection.

After the trigger is generated, an event is created after the elapse of the external event generation time. (Depends on the system setting) After the trigger is generated, create an event if the external event is occurring at the speed. (Depends on the system setting) Creates an event when a running pulse is input after the trigger is generated.

The function setting of the external input channels 8 to 10 is performed for each channel, and sets an interval for creating event data. The setting range is, for example, 5 to 3600 seconds,
The data used when creating the event data is obtained by averaging every eight data collected at regular intervals. This set value sets the collection interval at that time. The setting range is 10 to 65534 ms, and the abnormal value setting sets whether or not to use the function of the external input analog as a setting for an abnormal alarm. Event data can be created even when used as a setting for an abnormal alarm.
