Description

  The present invention relates to a vehicle temperature control device that performs heating control of a railway vehicle or the like.

In a railway vehicle or the like, heating is performed by a heater unit provided in a kick-in portion under a seat.
(A) of FIG. 10 is a figure which shows the structure of the seat seat lower part heater for a general railway vehicle. In this figure, 1 is a wall surface of the vehicle, 2 is a floor surface of the vehicle, and 3 is a seat. A heater unit 5 is provided in the kicking portion 8 below the seat, and the heater unit 5 is composed of a heating element 7 and a reflection plate 6. In addition, 8a is the kick board in which the vent hole 9 was opened.
In the seat seat lower heater configured as described above, when the heating element 7 is energized, the air warmed by the heating element 7 causes convection, and cold air enters from the lower vent hole 9 opened in the kick plate 8a. Warm air comes out from the upper air vent 9 of the kick plate 8a. Further, the radiant heat generated from the heating element 7 is radiated from the vent hole 9 to raise the temperature in the vehicle compartment. The room temperature is detected by a temperature sensor attached to the end wall of the vehicle at a position of 1.5 meters or more from the floor surface, and the energization control of the heating element 7 is performed by the temperature control device so as to maintain a predetermined room temperature. Be controlled.

At this time, the inside of the heater unit 5 becomes high temperature, and at the same time, the surface of the upper portion of the kick plate 8a becomes high temperature, which may cause a risk of burns.
Therefore, various devices have been proposed in the past to suppress the temperature rise at the upper portion of the kick plate 8a (for example, 65 ° C. or less) (Patent Documents 1 to 3).
FIG. 10B is proposed by Patent Document 1, and a heat shield member b1 is provided on the front surface of the heating element 7 attached to the upper part, and the radiant heat generated from the heating element 7 is applied to the upper part of the kick plate 8a. It tries to suppress the temperature rise of the upper part of the kicking part so as not to directly hit.
FIG. 10 (c) is proposed by Patent Document 2, and a partition plate c1 is provided between the upper and lower heating elements 7 so that the hot air does not concentrate on the top of the kick plate 8a by diffusing the convection hot air outlet. It is what I did.
FIG. 10 (d) is proposed by Patent Document 3, and a convection heating means is constituted by the heat radiation plate d1 and the positive temperature coefficient thermistor d2 fixed to the heat radiation plate d1, and the heating start-up in which passengers do not get on is performed. Sometimes the fan d3 is operated to blow warm air into the vehicle, and after the fan d3 stops, heating is performed by natural convection. The positive temperature coefficient thermistor d2 has a Curie point, and takes advantage of the feature that the specific resistance increases at a predetermined temperature, the power consumption decreases, and the heat generation is suppressed, and the temperature rise inside the kick-in portion 8 is prevented.

10 (b) and 10 (c) both improve the heater structure shown in FIG. 10 (a) and are devised so that heat does not concentrate on the top of the kick-in portion 8. However, in order to limit the temperature of the kicking portion 8, it is necessary to suppress the capacity of the heater. For this reason, when the room temperature is a low temperature of 5 ° C. or less, it takes time to increase the room temperature. Conversely, when the heating element is continuously energized when the room temperature is higher than 15 ° C., there is no way to detect the temperature rise of the kicking portion 8, so the kicking portion 8 becomes hot and burns occur. I was worried.
Further, in the case shown in FIG. 10 (d), since the fan d3 requires a rotationally movable part, if dust or the like under the floor is sucked and adhered, it may cause an unexpected failure, so maintenance is not performed frequently. must not. Further, in the case of temperature control using a positive temperature coefficient thermistor, the Curie point becomes a predetermined fixed temperature, so that there is a problem that the temperature inside the kick plate cannot be controlled in accordance with the surrounding temperature environment.

  Accordingly, the present invention provides a vehicle temperature control device that provides a comfortable in-vehicle environment temperature to the passenger at the same time as the vehicle operation and provides safety when using the seat of the passenger without any special device being applied to the heater unit. The purpose is to provide.

Furthermore, when preheating control data corresponding to the measured value of the room temperature by the first temperature sensor is stored in the storage means at the start of the preheating control, preheating is performed according to the stored preheating control data. The control is performed.

According to the vehicle temperature control apparatus of the present invention, since the second temperature sensor for detecting the temperature of the kicking portion is provided, the temperature of the kicking portion under the seat is monitored to be a dangerous temperature for the passenger. It is possible to prevent this, and it is possible to increase the capacity of the heating element provided in the kicking portion.
Further, the first preheating control in which the set temperature of the kick-in portion is set to be higher than the set temperature at the time of heating in the operation state at the time of standby until the operation of the vehicle (the time from the start of heating of the vehicle until the passenger is put on). In a short time, the indoor temperature can be raised to the indoor set temperature, and then, when the passenger gets on the vehicle by performing the second preheating control lower than the set temperature during heating in the operation state, The temperature of the upper part of the kicking section under the seat can be set to a temperature that is not dangerous to the passengers.
Furthermore, since the storage means for storing the preheating control data is provided and the preheating control data including the time required for the first and second preheating control and the temperature in the vehicle room when heating is started is stored, Optimum preheating control can be performed according to the preheating control data, and the amount of electricity consumed for preheating can be minimized.

And a second temperature sensor that detects the temperature of the upper portion of the kicking portion 8.
Further, 20 is a temperature control device for performing heating control of the vehicle, and 21 is attached to a position higher than 1.5 m from the vehicle floor surface 2 of the end wall 22 in the vehicle compartment, and is connected to the vehicle temperature control device 20 and connected to the vehicle. A first temperature sensor 23 for measuring the indoor temperature is a heating start command input switch for instructing the temperature control device 20 to start heating from the cab.

FIG. 3 is a block diagram showing a configuration of the temperature control device 20.
In this figure, 31 is a control unit that inputs an input signal from the outside and executes computations such as heating and preheating control to be described later, 32 is an operation signal of the heating start command input switch 23 from the driver's seat, 7 is an input / output circuit for outputting an on / off control output signal, 33 is an operation unit for performing various setting value input operations and various data output operations to the display unit 35, and 34 is the first temperature. An A / D converter that inputs signals from the sensor 21 and the second temperature sensor 4 and converts them into digital signals, 35 is a display unit that displays various internal data of the temperature control device 20, and 36 is a ROM or A memory 37, which is a RAM, is a storage unit such as a flash ROM for storing preheating control data related to preheating control.

In the vehicle temperature control device of the present invention configured as described above, the temperature control device 20 starts the heating control by operating the heating start command input switch 23 and inputting the heating start command.
In winter, a heating start command is input from the driver's seat about 2 hours before the vehicle is operated (passengers are on board). During the preheating control time of 120 minutes, In order to obtain a predetermined temperature for a short time, the heating control is performed by setting the set temperature of the kick section 8 under the seat to a value (for example, 110 ° C.) higher than the set temperature during heating in the operating state. The first preheating control and the set temperature of the kick-in part 8 are used so that the temperature around the seat does not become a temperature that may cause burns when the passenger sits on the seat 3 during operation (passenger is on board) The second preheating control for controlling the heating by setting a predetermined temperature lower than the set temperature at the time of heating in the state (for example, 47 ° C.) is performed, and then the set temperature of the kicking unit 8 at the time of heating in the operating state ( For example, normal control at 62 ° C) So that the heating control is performed.

Heating control is performed by on / off controlling the heating element 7 by time proportional control. That is, for each set value of the vehicle interior temperature and the kick-in portion temperature, an upper limit value and a lower limit value are provided with a predetermined temperature range (for example, ± 0.5 ° C) around the set value. A set value is changed to a triangular wave shape between a value and a lower limit value in a reference temperature cycle (for example, 15 minutes), and a temperature measured by the first and second temperature sensors is set with a temperature changing to the triangular wave shape as a reference temperature. If the reference temperature> the measured temperature, the control output is turned on, and if the reference temperature ≦ the measured temperature, the time proportional control is performed in which the control output is turned off. Here, in the present invention, an indoor temperature control output based on a comparison between a reference temperature of the vehicle indoor temperature and a temperature measured by the first temperature sensor, a reference temperature of the kick-in portion temperature, and a measurement by the second temperature sensor. The energization of the heating element 7 is controlled by the logical product of the kicking section control output based on the temperature comparison.
As described above, when the preheating control time is 120 minutes, the first preheating control and the second preheating control are performed in eight periods of a reference temperature period of 15 minutes (hereinafter simply referred to as “reference period”). Will be.

As will be described later, the setting of the preheating control time can be changed.
The reference temperature and the reference period can be arbitrarily set according to the control mode (for example, vehicle, heater capacity, regional difference, etc.).
For example, if the reference period is changed without changing the capacity of the heater, the time during which the heater is continuously energized changes. If the on-time is long, the temperature of the kicking section will rise, and even when off, preheating will increase the room temperature. Thus, the aspect of temperature rise can be changed by changing the reference period, and control according to regional characteristics and the like is possible.

FIG. 4 is a flowchart showing a temperature control operation by the temperature control device 20.
When the heating start command input switch 23 is turned on and a heating start command is input, first, an initial setting process is performed (step S1). Here, a preheating control time (120 minutes), a reference period (15 minutes), and the like are set.
Next, the first temperature sensor 21 measures the current vehicle interior temperature, and determines whether preheating control data corresponding to the measured value is stored in the storage unit 37 (step S2). As a result, when the corresponding preheating control data is stored, the first and second preheating controls are performed in accordance with the data (step S10), and then the normal heating control is performed (step S11).

When the preheating control data corresponding to the room temperature is not stored in the storage unit 37, the indoor temperature setting value is set to a predetermined value (for example, 22 ° C.), and the temperature setting value of the kicking unit (hereinafter, “ The first preheating control is started by setting the first set temperature (for example, 110 ° C.) higher than the set value during heating in the operating state. Then, the indoor temperature set value (22 ° C) is compared with the measured value (temperature in the vehicle interior) of the first temperature sensor 21 (step S4), and the vehicle indoor temperature is set to the set value (indoor temperature setting). Value) (when the room temperature control output is on), the setting value of the kicking portion (first setting temperature 110 ° C.) and the measured value of the second temperature sensor 4 (temperature of the kicking portion 8) (Step S5), and when the temperature of the kicking portion 8 does not reach the set value (the kicking portion set value) (the kicking portion control output is on), the heating element 7 is energized to increase the temperature. (Step S6) When the temperature of the kicking portion 8 reaches the set value (the kicking portion control output is off), the energization to the heating element 7 is stopped so as not to cause danger such as burning of the seat ( Step S7).
In step S4, when the vehicle room temperature reaches the set value (the room temperature control output is off), the power supply to the heating element 7 is stopped (step S12). Thereby, 1st preheating control is complete | finished.
In the first preheating control, the first set temperature, which is the set value for the kicking portion, is the temperature inside the vehicle compartment before the measured temperature value for the kicking portion reaches the first set temperature. The temperature is high enough to reach the set value.
Further, when the preheating control time elapses before either the temperature of the kick-in part or the vehicle interior temperature reaches the set value, the process shifts to the heating control in the operating state (steps S8 and S9).
When the first preheating control is completed, the data of the result of the first preheating control (information indicating the vehicle interior temperature measured value at the start of heating control and how many reference cycles are required for the first preheating control) Record in the storage unit 37 (step S13).

Subsequently, the second preheating control is started. That is, the heating control is started with the set value for the kicking portion set to a second set temperature (for example, 47 ° C.) lower than the set value for normal heating (step S14).
In step S15, it is determined whether or not the measured value of the second temperature sensor (temperature of the kicking section 8) has become lower than the setting value of the kicking section (second set temperature: 47 ° C.). When the kicking-in control output is on, the second preheating control is terminated, and information on the control result of the second preheating control (the number of reference cycles required for the second preheating control) is stored in the storage unit 37. (Step S16), and the routine proceeds to normal heating control in which the setting value of the kicking portion is set to the operating state setting value (62 ° C) (step S18).
Further, when the preheating control time elapses before the temperature of the kicking portion 8 falls to the setting value of the kicking portion (step S17), the routine forcibly shifts to normal heating control (step S18).

  As described above, in the vehicle temperature control apparatus of the present invention, the first preheating control for rapidly raising the vehicle interior temperature by setting the setting value for the kicking portion to a value higher than that during normal heating in the preheating control time, After the preheating control of 1 is completed, the second preheating control for setting the temperature of the kicking portion 8 to a safe temperature is performed by setting the setting value of the kicking portion to a value lower than that at the time of normal heating. Can be used to achieve safe and comfortable vehicle heating.

FIG. 5 shows an example in which heating control is executed when the outside air temperature is low (for example, 5 ° C.) and it takes a long time to raise the temperature in the vehicle compartment to a predetermined temperature (for example, 22 ° C.). FIG. It is assumed that the preheating control time (the total of the first and second preheating control times) is set to 120 minutes and the reference period is set to 15 minutes.
As described above, first, the first preheating control is started.
Kicking section set value (first set temperature: 110 ° C) reference temperature> measured value of second temperature sensor 4 Kicking section control output: On, indoor temperature set value (22 ° C) reference temperature> No. From the measured value of the temperature sensor 21, the indoor temperature control output is turned on, and both the kicking unit control output and the indoor temperature control output are on, so the heating element 7 is turned on and the temperature of the kicking unit 8 (second Both the temperature sensor 4) and the room temperature (first temperature sensor 21) continue to rise in temperature (reference cycles s1 to s6).
And in (1) of the seventh period (s7) of the reference period, the room temperature (measured value of the first temperature sensor 21) is higher than the reference temperature of the room temperature set value (reference temperature (room temperature set value)) ≦ The first temperature sensor), and the indoor temperature control output is turned off. Thereby, the heating element 7 is also turned off.
When the room temperature has reached the set range (reference temperature for temperature control), the first preheating control is terminated, and the control result of the first preheating control at this time is not stored in the preheating control storage unit Store. The content stored in the storage unit 37 includes (1) a measured value (for example, 5 ° C.) of the first temperature sensor 21 at the start of heating control, (2) control conditions, that is, a reference cycle, and an output of the heating element 7. Is the number of reference periods (in this case, s7 = 7). When the upper limit value and the lower limit value of the reference temperature can be changed, the reference temperature may be stored.
The first preheating control is completed by the above control sequence.

Subsequently, the second preheating control is executed.
In the second preheating control, the setting value for the kicking portion is set to a second setting temperature (for example, 47 ° C.) lower than the setting temperature for heating in the operating state, and the setting value for the kicking portion for the first preheating control is set. On the other hand, since it has been greatly lowered, the kicking section control output is turned off at the same time as entering the reference period s8 of the second preheating control.
When the heating element 7 is turned off, the temperature of the kicking section 8 decreases, and the temperature of the kicking section 8 (second temperature sensor 4) becomes lower than the reference temperature of the kicking section setting value of the second preheating control. (2) The kicking section control output is turned on. As a result, the heating element 7 is turned on and heated, the temperature of the kicking portion 8 rises, and the second temperature sensor 4 becomes higher than the reference temperature within the same reference period s8 (3), whereby the heating element 7 is turned off. Is done. In addition, when the measured value of the second temperature sensor 4 becomes lower than the reference temperature of the kicking set value, the second preheating control is finished, and normal heating control is performed from the next reference period. Become.
From the above, it is stored in the storage unit 37 that the reference period of the preheating control is 8 periods in the first preheating control and the second preheating control.

When the present inventors actually controlled the temperature of each part with the vehicle, the temperature measurement value (second temperature sensor 4) at the upper part of the kicking part 8 and the lower seat high temperature part 3a at the lower part of the seating sheet 3 When the measured temperature value is around 105 ° C, the high temperature portion 3a under the seat reaches a temperature of about 80 ° C, and when the former is around 60 ° C, the latter is measured at around 45 ° C. Further, the temperature measurement value of the kicking portion 8 and the temperature of the high temperature portion 3a under the seat when the heating element 7 is turned off and the temperature measurement value of the kicking portion 8 drops from around 105 ° C to around 60 ° C are almost the same. The same measured value was seen.
For this reason, the setting value of the kicked-in portion in the second preheating control is set at a temperature at which low temperature burns are difficult to occur (for example, 47 ° C: it takes about 45 minutes for low temperature burns to occur. It is used for trains (mountain line), etc., passengers will not get on for more than 45 minutes. Incidentally, if it is 55 ° C, it is said that low temperature burns will occur in about 12 seconds.) It is possible to provide a safe riding environment at an appropriate temperature for passengers.

As described above, after the temperature of the high temperature portion 3a in the lower part of the seat is once lowered to a temperature at which low temperature burns are not caused by the second preheating control, the set value of the kicking portion during normal heating (passenger is burned at low temperature in normal operation) By setting to a set temperature that does not become necessary (for example, 62 ° C.), safe and comfortable heating control can be executed.
That is, when the second preheating control is finished, the setting value of the kicking section is changed to the setting value at the time of normal heating, so that the temperature of the kicking section 8 becomes lower than the setting value of the kicking section at the normal time (4 ), The kick-in part control output is turned on, while the room temperature control output enters the second preheating control so that the room temperature (first temperature sensor 21) becomes lower than the room temperature set value and the room temperature control output is turned on. Therefore, the heating element 7 is turned on, the temperature of the kicking section 8 and the room temperature rise, and the room temperature can be controlled to the set temperature.

FIG. 6 is a diagram illustrating an execution example of the heating control when the outside air temperature is relatively high.
Since the vehicle temperature control method is the same as in the case of FIG. 5, the detailed description is omitted. However, in this case, since the outside air temperature is relatively high, the first preheating control is performed in three reference cycles (s1 to s3). It shows that it ended with. Furthermore, since the outside air temperature is high, the second preheating control requires two reference cycles (s4, s5).
The control data for the preheating control is stored in the storage unit 37 as described above.

FIG. 7 shows that the preheating control data in the case of FIG. 6 is stored in the storage unit 37, and the room temperature measured by the first temperature sensor 21 is the same as that in FIG. It is a figure which shows the example which performed heating control using the preheating control data of FIG.
In the case of FIG. 6, since the first preheating control is preheated in 3 reference cycles and the second preheating control is in 5 reference cycles of 2 reference cycles, the control unit 31 is given to the preheating control. Among the eight reference periods (s1 to s8), the preheating control is started from s4 by delaying the time of three reference periods of s1 to s3. This shows that even when the preheating control is performed with the start being delayed, the room temperature of the vehicle can be set to a predetermined temperature (for example, 22 ° C.) when the operation of the vehicle is started.
In this way, it is not necessary to use wasted power by executing the preheating control with a delay, so that energy saving can be realized.

In the description so far, the preheating control time (120 minutes) has been described as being fixed, but naturally it can be changed from the operation unit 33 for each temperature control device 20, and in this case, the preheating control time is also the preheating control data. Is stored in the storage unit.
The preheating control time may be changed by inputting a pulse signal in a predetermined form from the driver's seat using the heating start command input switch 23.
FIG. 8 is a diagram illustrating an example of an operation method of the switch 23 when the heating start command input switch 23 is used to change and set the preheating control time and start the heating operation.
The example shown in this figure is a switch operation with a continuous on time of 1 to 5 seconds, an off time of 1 to 5 seconds, and a continuous on time of 5 seconds or more or a continuous off time of 5 seconds or more. Is a significant input. The number of times of on time of 1 second or more and 5 seconds or less is information specifying the preheating control time, and information indicating the start of setting completion of the preheating control time is set to 5 seconds or more continuous on time or 5 seconds or more continuous off time. It is determined that it is. In addition, in the case of continuous on time of 5 seconds or more, it determines with it being the information which shows heating control start.
When the controller 31 of the temperature control device 20 detects an on time of 1 second or more and 5 seconds or less once before detecting a continuous on time of 5 seconds or more or a continuous off time of 5 seconds or more, When the preheating control time is set to 30 minutes and the on-time of 1 to 5 seconds is detected twice, the preheating control time is set to 60 minutes and the on-time of 1 to 5 seconds is detected three times. The preheating control time is set to 90 minutes, and when the on-time of 1 second to 5 seconds is detected four times, the preheating control time is set to 120 minutes and the heating control described above is started.
Thus, the operation of the heating start command input switch 23 is accurately performed by performing an on time of 1 second to 5 seconds and an off time of 1 second to 5 seconds at appropriate time intervals while the operator looks at the clock. It is possible to set the preheating control time.
Since the ON and OFF times are set to 1 second or more, erroneous counting due to contact chattering or the like can be prevented.
Further, by displaying the result of the operation of the heating start command input switch 23 on the driver's seat of the vehicle, the operator can check the preheating control time set for each vehicle without going to each vehicle. it can.

When the preheating control time is changed by the above method and the heating operation is started, as described above, the preheating control data suitable for the temperature at the start of the heating operation and the changed preheating control time is stored in the storage unit. If the storage unit has the preheating control data, the heating operation is started according to the preheating control data.
FIG. 9 is a diagram illustrating an execution example of the preheating control when there is no suitable preheating control data in the storage unit. This example shows a case where the heating control is executed by changing the preheating control time to 1 hour at the same outside air temperature as in the example of FIG.
In this case, the preheating control time is 60 minutes (4 reference cycles), and at this outside temperature, the first preheating control takes 3 reference cycles, so the second preheating control is 1 reference cycle (s4). Except for this, it is the same as the case of FIG. Thus, when the preheating control time has elapsed, the routine is forcibly shifted to normal heating control (step S17 in FIG. 4). In this case, since the preheating control is one reference period, the temperature of the kick-in portion is not sufficiently lowered at the start of normal heating.
