Description

Technical Field

[0001] This invention belongs to the field of device indicator lights, specifically a detachable indicator light and a method for controlling its illumination. Background Technology

[0002] In the field of industrial automation, spherical lights are frequently used to indicate the operating status of equipment, with different colors (usually red, green, and orange) representing normal operation, standby, and malfunction. However, when a malfunction occurs, the spherical lights typically only display the status near the equipment and cannot be seen by personnel in the entire area or other locations.

[0003] When equipment malfunctions and the indicator light turns red, only employees near the equipment can observe the light's status. This prevents maintenance personnel in the workshop from seeing the change in the light's status in a timely manner, making it difficult to troubleshoot equipment malfunctions promptly. In addition, for these fixed indicator lights, we cannot move them into the line of sight of managers (such as their desks or seats) to urge them to resolve the malfunction as quickly as possible, which also makes it difficult for employees to troubleshoot equipment malfunctions efficiently. Summary of the Invention

[0004] Purpose of the invention: To provide a detachable indicator light and a method for controlling its illumination, which can move the light to a place visible to equipment maintenance personnel in the workshop after a production equipment malfunctions and the indicator light color changes, to notify the equipment maintenance personnel to quickly repair the production equipment, or place it directly on the desk of the manager to urge the equipment maintenance personnel to quickly repair the production equipment, which greatly improves the maintenance efficiency of production equipment and solves the problem of low maintenance efficiency of production equipment due to the inability to notify relevant personnel in a timely manner in the existing technology.

When the production equipment is normal, the lamp holder emits light of the first color.

[0032] S101. When the production equipment is malfunctioning, the lamp head emits a second color light, and then the lamp head and base are checked for separation.

[0033] S102. When the lamp head is on the base, the lamp head continues to emit a second color light.

[0034] S103. When the lamp head separates from the base, the lamp head emits a third color light, and then the separation time between the lamp head and the base is checked to see if the predetermined time has been reached.

[0035] S104. If the lamp head and base are separated for less than the predetermined time, the lamp head will continue to emit the third color light.

[0036] S105. When the lamp head and base are separated for a predetermined time, the lamp head emits a second color light, and then the system continues to detect whether the lamp head is put back into the base.

[0040] The beneficial effects of this invention are: This application receives external signals through the signal unit of the base and wirelessly connects the control circuit with the signal unit. When a fault occurs in the production equipment, the signal unit sends a fault signal to the control circuit, which then controls the light-emitting unit to change the color of the light emitted, so that the light-emitting unit emits light of a color corresponding to the fault signal.

[0041] When the lamp head and lamp holder are connected, and the rechargeable battery and control circuit are connected to the charging unit, the charging unit can directly power the light-emitting unit, ensuring the normal operation of the light-emitting unit.

[0042] It can power the light-emitting unit with the rechargeable battery when the lamp head and lamp holder are separated, and the rechargeable battery and control circuit are separated from the charging unit, thus ensuring the normal operation of the light-emitting unit.

[0043] In summary, the detachable indicator light of this application can be moved to a place visible to equipment maintenance personnel in the workshop after a production equipment malfunctions and the indicator light color changes, notifying them to quickly repair the production equipment. Alternatively, it can be placed directly on the desk of management personnel to urge them to quickly repair the production equipment. This greatly improves the maintenance efficiency of production equipment and solves the problem of low maintenance efficiency caused by the inability of existing technologies to promptly notify and urge relevant personnel.

[0076] Working principle: such as Figure 4 As shown, the method for controlling the detachable indicator light to emit light includes: S100, connecting the lamp holder of the detachable indicator light to the electrical control system of the production equipment, then initializing the electrical control system of the production equipment, and then the electrical control system detects whether the production equipment is normal. When the production equipment is normal, the lamp holder 2 emits the first color light.

[0077] S101. When the production equipment is not working properly, the lamp head 2 emits a second color light, and then the lamp head 2 is checked to see if it is separated from the base 1.

[0078] S102. When the lamp head 2 is on the base 1, the lamp head 2 continues to emit the second color light.

[0079] S103. When the lamp head 2 separates from the base 1, the lamp head 2 emits a third color light, and then the separation time between the lamp head 2 and the base 1 is checked to see if the predetermined time has been reached.

[0080] S104. If the separation time between the lamp head 2 and the base 1 has not reached the predetermined time, the lamp head 2 continues to emit the third color light.

[0081] S105. When the time between the lamp head 2 and the base 1 reaches the predetermined time, the lamp head 2 emits a second color light, and then the system continues to detect whether the lamp head 2 is put back into the base 1.

[0082] S106. When the lamp head 2 is separated from the base 1 for a predetermined time and the lamp head 2 is not put back into the base 1, the lamp head 2 emits a second color light.

[0083] S107. When the lamp head 2 is separated from the base 1 for a predetermined time, and the lamp head 2 is put back into the base 1, check whether the production equipment is normal.

[0084] S108. Repeat the process from S100 to S107.

[0085] By emitting at least three different colored indicator lights and coordinating these different colors, the system can provide workers with information on the working status of production equipment or detachable indicator lights. When production equipment malfunctions and the indicator light color changes, the light can be moved to a location visible to maintenance personnel within the workshop to notify them to quickly repair the equipment. Alternatively, it can be placed directly on a manager's desk to urge maintenance personnel to repair the equipment promptly, greatly improving the maintenance efficiency of production equipment. Example

[0086] The detachable indicator light is mainly divided into two parts: the base 1 and the lamp head 2.

[0087] The function of base 1 is to connect cable 4 interface, mainly for 24VDC input and signal status detection.

[0088] Lamp head 2 is the core component of the entire product, mainly consisting of 8 red, 8 green, and 8 orange LEDs, one MCU chip, one BUCK chip, one Boost chip, one charging control chip, and one rechargeable battery 25. The MCU chip is the core component of the entire system. 24VDC is divided and supplied to the MCU chip's A / D port 211 to determine whether lamp head 2 has external 24VDC power, i.e., whether it is connected to base 1. Signal unit 12 receives the device status to control the LED color changes. After the 24VDC input, it passes through the BUCK chip circuit and outputs 5VDC, which powers the MCU and charging chip respectively. The rechargeable battery 25 is boosted to 24VDC by the Boost chip to power the LEDs. The three LEDs are controlled through the PWM port 213 output by the MCU.

[0089] Main working process: The MCU chip detects whether the base 1 and the lamp head 2 are connected through the A / D port 211. It determines whether they are connected under a certain voltage and disconnected under another voltage. When connected, the MCU chip illuminates the corresponding color of the lamp head 2 according to the external input signal. When the device detects an abnormality and is in a disconnected state, the third color of the lamp head 2 is illuminated, and the MCU chip's timer starts counting. If the lamp head 2 is still not connected to the base 1 after the predetermined time, the second color of the lamp head 2 is illuminated. This continues until the bulb is placed on the lamp holder and the device detects a normal connection, at which point the lamp head 2 reverts to its original first color.

[0090] As described above, although the invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the invention itself. Various changes in form and detail may be made without departing from the spirit and scope of the invention as defined in the appended claims.
