Description

  The present invention relates to a traffic signal controller, for example, a traffic signal controller having a setting interface capable of setting a desired constant for control using display means and input means.

  The traffic signal controller that controls the traffic signal can be set in various settings in order to perform advanced system control and wide area control (surface control) corresponding to traffic flow fluctuations. FIG. 4 shows an example of an operation panel of a conventional traffic signal controller. As shown in the figure, the number displayed on the display panel 120 is changed as desired by operating a setting button 130 for inputting various settings. Specifically, in order to change the number displayed on the display panel 120, the operator needs to press the setting button 130 arranged under each number, and the number is “1” by pressing once. Only to increase. The meaning of the numbers on the display panel 120 can be grasped from the correspondence table 140 provided on the upper side of the display panel 120. Moreover, the technique provided with the same operation panel as a simple traffic signal controller for construction is disclosed (for example, refer patent document 1).

JP 2007-148539 A (FIG. 2)

  By the way, in the technique disclosed in the operation panel of FIG. 4 and Patent Document 1, since buttons are provided corresponding to the respective numbers, there is an advantage that the numbers to be changed can be directly operated. As described above, there is a problem that only an increase operation can be performed as the button is pressed, and if the button is pressed too much, it is necessary to keep pressing until the number is completed. In addition, there is a feature that it is easy to press the next button, and there is a problem that if it is pressed incorrectly, it is not a number to be changed, but it also requires a troublesome operation. Introduction was sought. In addition, there is a demand for a large number of operation buttons to reduce the number of buttons from the viewpoint of miniaturization and the like.

  This invention is made | formed in view of such a conventional situation, and it aims at proposing the technique which improves the operativity of a traffic signal controller. Another object of the present invention is to propose a technique for realizing operability in which an operation error is unlikely to occur.

The apparatus according to the present invention relates to a traffic signal controller. The traffic signal controller includes a display unit capable of displaying a plurality of numbers, a change button having four buttons arranged in a cross shape at four locations on the top, bottom, left, and right for changing a set value displayed on the display unit. An operation panel having an auxiliary button that is pressed simultaneously with the change button in order to make it possible to change a predetermined setting item, and among the plurality of numbers when the left and right buttons are pressed among the change buttons, Specify which number to change, and increase or decrease the number by pressing the up and down buttons.
Further, when the setting value is largely changed from the default value, the pressing of the change button may be accepted in a predetermined operation different from normal.

  As mentioned above, according to this invention, the technique which improves the operativity of a traffic signal controller can be proposed. Further, from another viewpoint, it is possible to realize operability that is unlikely to cause an operation error.

It is the figure which showed the external appearance of the operation panel based on embodiment. It is a functional block diagram which shows schematic structure of the traffic signal controller based on embodiment. It is a flowchart which shows the change operation | movement of the setting value of the traffic signal controller based on embodiment. It is the figure which showed the external appearance of the operation panel based on background art.

  Next, modes for carrying out the present invention (hereinafter, simply referred to as “embodiments”) will be specifically described with reference to the drawings. In the embodiment described below, four buttons are arranged in a cross (up, down, left, and right) in order to change items to be set and input numbers. In order to perform a predetermined operation, it is necessary to simultaneously press an auxiliary switch provided separately in order to prevent erroneous input as much as possible.

  Furthermore, as described above, the traffic signal controller can be used as a set value (parameter) for the time required to complete the signal display for advanced system control and wide area control (surface control) corresponding to traffic flow fluctuations. A certain split, an offset that is a difference provided in the green signal start time of an adjacent intersection, a cycle length that is a time allocated to each display among the times of one cycle of the split, and the like are set. When these are changed, usually there are many fine adjustments. Therefore, when a large change is made from the current set value, an erroneous input is prevented by increasing the required input operation. Details will be described below.

  FIG. 1 is a diagram showing an operation panel 11 of a traffic signal controller 10 according to the present embodiment. The operation panel 11 includes a display unit 20 configured with LEDs that can display 6-digit numbers, an operation unit 30 configured with various buttons, and settings representing setting items corresponding to the numbers displayed on the display unit 20. The content correspondence table unit 21 is provided. In addition, a small lamp is provided at the lower right of each of the six LEDs, and indicates that the number whose lamp is lit is the operation target number currently set. In the figure, the third number from the left displayed as “2” is selected.

  As shown in the figure, the setting content correspondence table section 21 is divided into two stages and shows items that can be set. Specifically, it is shown that when the upper “time switch” group is selected, numbers related to two types of “item number” and “setting data” are displayed on the display unit 20. In addition, when “pattern setting” in the lower row is selected, it is shown that numbers relating to three types of “pattern”, “floor”, and “elapsed time (seconds)” are displayed on the display unit 20. Which group is selected is clearly indicated by lamps 24a and 24b provided on the right side of each group name. In the drawing, it is shown that “pattern setting” is selected. The number displayed on the display unit 20 is “102005”, which means that the pattern is “1”, the floor is “02”, and the elapsed time is “005” seconds.

  The operation unit 30 includes a cross button 31 disposed on the right side of the operation panel 11, an auxiliary switch 36 disposed above the cross button 31, a setting / execution button 37 disposed below the auxiliary switch 36, A setting group change button 35 arranged at the lower left of the display unit 20 is provided.

  The cross button 31 has two numeric selection buttons 32 arranged at the top and bottom to change the number displayed on the display unit 20 and two numeric position selections arranged at the left and right to select the location of the number to be changed. Button 34. More specifically, the numerical value selection button 32 includes an increase button 32a provided on the upper side to increase the number by “1” and a decrease button 32b provided on the lower side to decrease the number by “1”. Yes. The number position selection button 34 includes a left movement button 34a provided on the left side for moving the selection of the number to be changed to the left, and a right movement button 34b provided on the right side for moving to the right. And. In addition, as shown above, which place number is selected is indicated by lighting of the lower right lamp of each number.

  The auxiliary switch 36 is a switch provided for preventing erroneous input in order to input a specific set value. Specifically, when changing an item in a specific group, the operator needs to operate the cross button 31 while pressing the auxiliary switch 36 in order to be more careful. The setting / execution button 37 is pressed when starting and ending various settings of the traffic signal controller 10.

  The setting group change button 35 is a button for selecting a group that can be set with the cross button 31 from two types. As described above, selectable group names and the like are shown in the setting content correspondence table section 21.

  In addition to the above, buttons and display lamps are shown, but since they are not related to the features of this embodiment, description thereof will be omitted.

  Next, the main body of the traffic signal controller 10 operated by the operation panel 11 shown in FIG. 1 will be described. FIG. 2 is a functional block diagram illustrating a schematic configuration of the traffic signal controller 10. Here, the functional block diagram which mainly paid attention to control of the setting operation | movement to the traffic signal controller 10 is shown.

  The traffic signal controller 10 includes a main control unit 90 that comprehensively controls each component of the device, a signal control unit 60 that controls the operation of the traffic signal, and a time-lapse unit that counts time in synchronization with a radio clock or the like. 80, the operation unit 30, the setting operation control unit 40 for controlling the setting operation, the display unit 20, the display control unit 22 for controlling the display, and the setting table 70 for recording setting values. Prepare. The setting table 70 includes an initial value table 72 in which initial values at the time of product shipment are recorded for various setting values, and a user setting table 74 in which setting values changed to desired values by a user are recorded.

  Regarding the traffic signal controller 10 having the above configuration, the setting value changing operation will be described with reference to the flowchart of FIG.

  When the operator presses the setting / execution button 37, more specifically, for example, when the setting group change button 35 is long pressed, the setting operation control unit 40 receives an instruction by the pressing and receives various instructions. A constant change mode in which the set value can be changed is started (S12). A dedicated button for starting the constant change mode may be provided. In addition, a key switch or the like may be used to be more careful.

  Then, when the constant change mode starts, the setting operation control unit 40 refers to the user setting table 74, acquires the currently set value, and displays the acquired number on the display control unit 22. Instruct. In response to the instruction, the display control unit 22 displays the set value on the LED of the display unit 20 (S14). At this time, the lower right lamp of the currently set number is turned on by the numerical value selection button 32, and the operator selects the numerical position to be changed by the numerical position selection button 34.

  Next, the setting operation control unit 40 confirms whether or not the auxiliary switch 36 is pressed (S16). If the auxiliary switch 36 is pressed (Y in S16), a numerical value selection button is usually used as the specific operation mode. It is determined that the item that cannot be operated in 32 can be changed (S18). When the auxiliary switch 36 is not pressed and when the auxiliary switch 36 is released during the subsequent processing (N in S16), the setting operation control unit 40 determines that the specific operation mode is not set.

  Then, after determining whether or not the above-described specific operation mode is set, the setting operation control unit 40 determines whether the user's operation is a press of the numerical value selection button 32 or a numerical position selection button 34. (S20). When the numerical position selection button 34 is pressed (N in S20), the setting operation control unit 40 instructs the display control unit 22 to shift the target of the setting item in response to the pressing of the numerical position selection button 34. The display control unit 22 reflects the instruction on the display of the display unit 20 (S22). That is, if the left movement button 34a is pressed, the numerical position of the selection target is moved to the left, and if the right movement button 34b is pressed, the numerical position of the selection target is moved to the right.

  When it is determined that the numerical value selection button 32 is pressed in the process of S20 (Y of S20), the setting operation control unit 40 determines whether or not the number reflecting the pressing is a predetermined value or more away from the default value. Is determined (S24). When it is determined that the distance is greater than the predetermined value (Y in S24), the setting operation control unit 40 shifts to a careful mode (S26). In this careful mode, for example, the number set before the start of the setting operation is “5”, but when the number is increased or decreased by “4” or more, it is assumed that it is a big change. The number is changed by pressing the button continuously. More specifically, when entering the cautious mode, first, the setting operation control unit 40 determines whether the increase / decrease of the number is in a direction away from the predetermined value or a direction in which it approaches (S28). . When it is determined that the direction is away (Y in S28), the setting operation control unit 40 determines whether or not the pressing is performed twice in a predetermined time (S30). When it is determined that the button is not pressed twice in succession (N in S30), the setting operation control unit 40 does not accept the pressing of the numerical value selection button 32 by the operator, and returns to the process of S16. At this time, an error may be output.

  If it is determined that the button is pressed twice continuously (Y in S30), the setting operation control unit 40 determines that the operator's pressing of the numerical value selection button 32 is an appropriate operation, reflects the change operation, and The display control unit 22 is instructed to display the number after reflection, that is, the number increased or decreased by 1, and the display control unit 22 receives the instruction and displays it on the display unit 20 (S32).

  Also, in the case where it is determined in the process of S24 that the predetermined value is not more than the predetermined value (N in S24), the setting operation control unit 40 reflects the change operation (S32).

  When the operator's operation is reflected by the process of S32, the setting operation control unit 40 determines whether there is an instruction to end the constant change mode by pressing the setting / execution button 37 (S34), and the end instruction If there is no (N in S34), the process returns to S16, and if there is an end instruction (Y in S34), the process according to this flow ends.

  As described above, according to the traffic signal controller 10 of the present embodiment, the number of buttons for changing the setting value of the operation panel 11 can be reduced by using the four cross buttons 31. Further, it is not necessary to arrange the display unit 20 immediately below. As a result, the degree of freedom in designing the layout of the buttons on the operation panel 11 is increased. On the other hand, since countermeasures against erroneous input and the like have been taken, it is possible to prevent a reduction in worker's work efficiency.

  The present invention has been described based on the embodiments. This embodiment is an exemplification, and it will be understood by those skilled in the art that various modifications can be made to combinations of these components, and such modifications are also within the scope of the present invention. For example, the traffic signal controller 10 requested that the numerical value selection button 32 be pressed twice continuously for a predetermined time when the set value is greatly changed, but from the viewpoint of making the operator recognize that the change is greatly changed. The reaction rate may be slowed so that quick continuous presses are not accepted.
