In this case, the temperature data recorded in the temperature recorder 130 may be recorded in units of 1 minute, and the recording monitoring time may be set to 10 minutes.

In addition, the controller 180 detects a voice around the refrigeration vehicle when outputting a voice to detect a voice alarm interference factor, and outputs a voice alarm in a form that can avoid the voice interruption factor.

Next, an operation of the temperature management device for a refrigerating/freezing vehicle having a voice alarm function configured as described above will be described with reference to the flowchart shown in FIG. 4 .

First, when the driver turns on the vehicle ignition, the vehicle start-on information is received from the vehicle ECU 10 and vehicle power is supplied to the temperature management device 100 , and the driver turns on the temperature management device 100 . Turn on the power of the unit and set it to the operating state (ST100).

In the state that the vehicle ignition is on, the driver registers information on temperature maintenance items such as food or medicines currently loaded in the freezer 2 through the temperature management device 100, and The freezer operation information including the freezer set temperature is registered (ST200). In this case, the registration of the product information and the freezer set temperature can be performed so that the driver's voice authentication is normally passed, and it is registered once at the initial stage of transporting the goods, and is cleared when the transport of the goods is completed.

And, in step ST200, the freezer operation information may additionally include compressor defrost time, defrost cycle, ON_OFF width, compressor oil replacement time, evaporator fan replacement time, and condenser fan replacement time, and this additional information is provided by the driver or manager can be set arbitrarily at any time.

After that, when the driver starts driving the refrigerated vehicle, driving information is applied from the ECU 10 to the temperature management device 100 (ST300), and the temperature management device 100 performs the door sensor 300 based on this (ST300). It determines whether the freezer door is in an open state by checking the open detection information received from the do (ST400). At this time, the temperature management device 100 provides driving stop information to the ECU 10 to forcibly turn off the start of the refrigerated vehicle, so that the refrigerated vehicle cannot run with the freezer door open.

When it is determined that the refrigeration vehicle starts driving and the freezer door is not opened in the ST300 step, the temperature management device 100 provides refrigeration vehicle guidance information including the freezer operation information and the freezer height registered by the driver in the ST100 step. is audio output (ST500). For example, through the speaker 140, "The current refrigerator temperature is 15.5 degrees, the set temperature is -20 degrees, the defrost time is 10 minutes, the defrost cycle is 3 hours, the ON_OFF width is 3 degrees, and the height of the freezer is 1.8 meters. It is operating normally. Please drive safely". That is, the temperature management device 100 provides voice guidance of the current state of the freezer and the height of the vehicle tower before the refrigeration vehicle starts driving, so that the driver can recognize it.

In addition, in a state in which the refrigerated vehicle is running, the temperature management device 100 drives the camera 150 to capture a photographed front image, and acquires the height of height-limited facilities such as an underpass or tunnel from the photographed front image. After determining whether the height-restricted facility can pass by comparing the height of the height-restricted facility with the height of the freezer, if the height-restricted facility cannot pass, the height-restricted facility located in the front cannot pass through the speaker 140 A facility driving impossibility alarm guiding a voice is output (ST600). At this time, when the temperature management device 100 interlocks with the vehicle navigation system 20 when driving the vehicle, if a height-limited facility is located on the vehicle driving path, the front image is captured through the camera 150 to determine whether the height-limited facility is running. can be carried out to determine And, in the step ST600, when it is determined that the passage of the height-restricted facility is impossible, the temperature management device 100 may request to guide another route through the navigation system 20 .

In addition, in a state in which the refrigeration vehicle is running, the temperature management device 100 collects the freezer temperature from the temperature sensor 300 at a preset period and records it in the temperature recorder 130 in units of time, and in units of preset recording monitoring time. The temperature recording state of the temperature recorder 130 is monitored (ST700). At this time, the temperature management apparatus 100 may read the memory address in which the temperature data of the temperature recorder is recorded and determine whether the temperature recorder 130 is operating normally based on the presence or absence of data recording.

In addition, in a state in which the refrigeration vehicle is running, the temperature management device 100 compares the freezer temperature collected from the temperature sensor 300 with a preset set temperature. It is determined that the above is abnormal, and an alarm of abnormal temperature of the freezer is outputted through the speaker 140 (ST800). At this time, when the freezer temperature differs from the set temperature by more than a certain amount, the temperature management device 100 checks the current operating state of the freezer unit 200 and alarms the freezer unit abnormality corresponding to the operating state of the freezer unit 200 . , for example, a disconnection alarm of the corresponding unit may be outputted by voice.

The above-described operations ST600 to ST800 are continuously performed until the driving of the refrigerating vehicle is finished (ST900).

In addition, in the present invention, in the state in which the refrigeration vehicle is running, the use time of the freezer unit 200 is accumulated and counted from the previous use time until the refrigeration vehicle ends running in the temperature management device 100, and each unit By comparing the accumulated count time with the preset exchange time, an exchange alarm for the freezer unit whose accumulated count time is longer than the exchange time is output as a voice.

On the other hand, in the present invention, in outputting the voice alarm, when the radio is turned on in the refrigerated vehicle, the driver is on a call or talking with another passenger, or driving in a noisy place such as a market or a construction site, the driver can use the voice There may be cases where the alarm is not recognized properly.

Accordingly, in the present invention, a method for outputting a voice alarm by avoiding the presence of such a voice alarm interference factor in the vicinity of a refrigeration vehicle will be described with reference to the flowchart shown in FIG. 5 .

First, in the present invention, the type of alarm information outputted by voice is divided into event alarms such as door opening, freezer temperature abnormality, and freezer unit replacement, and periodic alarms such as whether the temperature data of the temperature recorder is recorded.

In the above state, when a voice alarm output is requested, the temperature management device 100 detects a voice around the vehicle through the microphone 160 and determines whether there is a voice alarm interference factor (ST10). In this case, the voice alarm disturbing factor may include a noise level, an auditory factor such as a voice or music, a visual factor in which the driver's attention is concentrated to one place due to snow/rain, and the like.

If there is no voice alarm interfering factor in step ST10, the temperature management apparatus 100 outputs a corresponding voice alarm (ST20).

On the other hand, if it is determined in step ST10 that there is a voice alarm interfering factor, the temperature management device 100 determines whether the corresponding alarm information type is an event type (ST30), and if it is an event type, the corresponding voice alarm interferes with the voice alarm A voice alarm is output by changing the factor to an avoidable form (ST40). At this time, the avoidable forms are methods such as amplifying the voice alarm output level, controlling the voice output speed, providing a voice alarm simultaneously with other sensory responses such as sight, touch, and smell, outputting at a time when there is no or reduced voice output interference factor, etc. This can be applied.

If the alarm information type is a periodic type in step ST30, the temperature management device 100 stores and delays the corresponding voice alarm content (ST50). It is determined whether the current voice environment of the refrigeration vehicle is a voice environment lower than a reference level by detecting the information (ST60). At this time, the temperature management device 100 sequentially stores the periodic type voice alarm until the current voice environment of the refrigeration vehicle becomes a voice environment below the reference level.

Then, when it is determined that the current voice environment of the refrigeration vehicle is a voice environment below the reference level, the temperature management device 100 determines whether the currently stored voice alarm content is greater than or equal to a certain amount (ST70), and when it is less than a certain amount, the stored voice alarm is sequentially performed to output audio (ST80). For example, when there are three or less stored voice alarms, the voice alarms stored up to now may be sequentially outputted.

On the other hand, if the currently stored voice alarm content exceeds a certain amount in step ST70, the temperature management apparatus 100 newly generates integrated voice alarm information abbreviated to the voice alarm content stored so far and outputs the voice (ST90).

That is, the temperature management device 100 separates each voice alarm content into common message information and individual guide information form, extracts individual guide information from each voice alarm content sequentially to generate integrated guide information, and provides common message information and The integrated voice alarm information in the form of synthesizing the integrated guide information is generated and the voice is output.

For example, 5 periodic alarms

"The temperature data was normally recorded on the thermograph at 13:10."

"The temperature data was recorded normally on the thermograph at 13:20"

"The temperature data was normally recorded on the thermograph at 13:30"

"The temperature data was normally recorded on the thermograph at 13:40"

If "Temperature data was normally recorded in the temperature recorder at 13:50" is saved,

Creating integrated guidance information consisting of individual guidance notes of "13:10, 13:20, 13:30, 13:40, 13:50",

The integrated voice alarm information of "The temperature data was normally recorded on the thermograph at 13:10, 13:20, 13:30, 13:40, 13:50" is generated and outputted.
