Description

Storage area active safety warning system

A safety warning system, particularly a storage area active safety warning system that can be used to actively remind the driver of a crane to leave the controlled area when the crane in the factory enters the controlled area.

Please refer to FIG. 6, which is a schematic plan view of a general factory building 100. The plant 100 can place different materials according to requirements. For example, a weight will be placed in the hot-rolled steel strip factory, and the crane 90 installed in the plant 100 will be used to hang the weight to the scale; When there is a demand for the use of the raw material of the steel embryo, the crane 90 is used to hang the raw material to the designated place.

In the plant 100, a control room 110 is often set as the command center of the plant 100. In the control room 110, staff can control the number of various materials, parts, and control the travel route of the crane 90 to send the materials smoothly. Designated place. A control area 120 is planned on the periphery of the control room 110, and the control area 120 may also be a storage area for other parts or an area where workers will stay on site for a long time.

In order to prevent the crane from accidentally hitting the control room 110 when lifting materials and parts, or to prevent hanging objects and workpieces from accidentally falling and smashing into the control room 110 and nearby workers, the current safety mechanism is in Warning lights L are set around the control area 120. When the crane driver controls the crane 90 to lift materials, the warning lights L are illuminated with red light or flash to remind the crane driver of the area of the control area 120. And actively avoid it to avoid accidents caused by the crane driver accidentally entering the control area 120 and hitting the control room 110.

However, when the crane driver operates the crane 90, due to blind spots or negligence, he fails to pay attention to the positions of the warning lights L, so that the crane driver cannot immediately detect that he has entered the control area 120 by mistake, increasing accidents. Chance. Furthermore, if the driver of the crane does not find the warning lights L after entering the control area 120, the crane 90 will stay in the control area 120 until the crane 90 leaves the control area 120. In the process, there is no warning mechanism to promptly notify the driver of the crane that he must leave the control area 120 immediately, nor can the driver of the crane be notified of the negligence of the driver in time to increase their awareness of compliance, and it will also increase the probability of accidents.

Furthermore, since whether the crane 90 entered the control area 120 is only judged by the driver of the crane, there is no mechanism to record the event status of the crane 90 entering the control area 120, and the crane 90 entering and leaving the control area. Relevant operational data such as the time in the area 120, how long the person stays in the control area 120, the identity of the crane driver, and the like. The management personnel cannot accurately grasp the time and frequency of the crane 90 entering the control area 120, and cannot effectively improve the frequency of accidents.

In order to effectively prevent the crane driver from accidentally entering the controlled area in the factory building, the new model provides an active safety warning system for the storage area, which uses different axial positioners to locate and record the coordinates of the crane at any time, and the crane enters the restricted area at any time. At this time, the control computer of the crane can actively and timely notify the driver to prevent the driver from driving the crane into the restricted area.

In order to achieve the above purpose, the storage area active safety warning system provided by the present invention is set in a storage area where a day car is installed, wherein the sky car includes a large car and a small car capable of moving on the large car; the The storage area active safety warning system includes: a day car control module, which is provided in the trolley and is used to control the movement of the car in the storage area, and records the at least one operation record of the crane, the crane control module Storing a coordinate of the control area; A locator module is provided to electrically connect the dolly to the crane control module, and is used to locate the location of the crane in the storage area to generate a day's car coordinates, and transmit the crane's coordinates back to that day. A vehicle control module; a first warning unit electrically connected to the crane control module and arranged in the cab of the car; the first warning unit is used to generate a first warning signal; a central server, It is used for receiving at least one operation record of the overhead crane in real time; a wireless transmission device is electrically connected with the central server and wirelessly connected with the overhead crane control module for transmitting the at least one operation record back to the central A server; wherein, when the crane control module calculates that the crane coordinates fall in the coordinates of the controlled area, the crane control module activates the first warning unit to issue the first warning signal to remind the crane driver to leave Regulatory area.

According to the present invention, the first warning unit is set in the crane cab of the crane. When the crane control module calculates that the coordinates of the crane fall in the coordinates of the control area, the crane control module activates the first warning. The unit reminds the driver that he has entered the area of the restricted area and must immediately leave the restricted area, which can effectively inform the driver.

The new model may further include a second warning unit, which may be a voice device. When the overhead crane enters the restricted area, the driver is reminded to enter the restricted area by broadcasting a warning notice, and must leave immediately. The restricted area, in conjunction with the first warning unit, simultaneously reminds the driver with visual and auditory stimuli, so that the driver can perceive and correct the moving direction of the crane to avoid the area of the restricted area.

Furthermore, since the crane control module can calculate whether the crane has entered the range of the restricted area at any time, the crane control module will control the first warning unit during the period when the crane is located in the restricted area. 2. The second warning unit continuously sends out warning signals. Even if the driver has entered the restricted area, he can continue to send the warning signal to notify the driver to drive the crane away from the controlled area to prevent the crane from staying in the control for a long time. Area, increasing risk.

In addition, the crane control module will also record operation data such as the position of the crane, the time of entering and exiting the control area, the time to stay in the control area, and the identity of the driver, and return the operation data to the center. Stored by the server, the staff can read the operation data from the central server at any time, sort out the violation of the driver, the driving date, time, and the weight of the workpiece, and feed it back to the relevant personnel to implement the circular quality management (PDCA) CHECK and ACTION mechanisms to ensure the safety of personnel in the controlled area.

If the number and range of the control area is adjusted by the storage area due to operation requirements, for example, some machines and equipment in the storage area are under maintenance, the coordinate of the adjusted control area is entered into the crane control module, and the crane The control module can automatically issue a warning signal when the crane enters the new controlled area. It does not need to rely on the driver to look for the position of the lamp with the naked eye to ensure the safety of the workers under the crane.

Please refer to FIG. 5, and then explain the flow of steps in the practical application of the new model. First, a flowchart for determining the coordinates of the crane when the crane 80 enters the control area will be described.

S10: Receive the crane coordinates. The crane control module 30 can receive the crane coordinates once within a time period. For example, the crane control module 30 receives the X-axis coordinate generated by the X-axis positioner 41 and the Y-axis coordinate generated by the Y-axis positioner 42 every two seconds.

S20: Determine whether the bit value of the flag register is 0. The flag register is set in the crane control module 30 to store the state of the crane 80 in the previous time period.

If the bit value of the flag register is 0, then:

S21: Determine whether the crane coordinates are located within the coordinates of the restricted area. For example, the coordinates of the restricted area are (27400 ≦ X ≦ 29090, 1350 ≦ Y ≦ 2700), and the crane control module 30 determines whether the position of the crane 80 is within the coordinates of the restricted area.

If the determination result is YES in step S21, then

S211: Start the first warning unit 50 and the second warning unit 60. When the crane 80 enters the coordinates of the restricted area, the crane control module 30 activates the first warning unit 50 and the second warning unit 60 to remind the driver to leave the coordinates of the restricted area as soon as possible.

S212: Send an entry signal to the central server 10. Since the crane 80 enters the coordinates of the controlled area, the crane control module 30 sends the entry signal to the central server 10. The entry signal may include, but is not limited to, the identity (ID), operator number, operator name, crane position, weight, date and time of entering and exiting the warning area of the crane.

S213: Change the bit value of the flag register to 1. Since the crane 80 enters the coordinates of the control area, and the bit value of the flag register in the previous time period is 0, the crane control module 30 sets the bit of the flag register The meta value is changed to 1.

If the judgment result is NO in step S21, it means that the crane 80 has not entered the control area C, then

S30: Waiting for the next vehicle coordinate on that day. The crane control module 30 continues to receive the crane coordinates sent by the locator module 40.

Next, the steps of the crane 80 leaving the control area C will be described.

In step S20, if the bit value of the flag register is not 0, it means that the crane 80 was within the coordinates of the control area in the previous time period, then:

S22: Determine whether the coordinates of the crane are outside the coordinates of the control area. For example, the coordinates outside the restricted area are (X> 29090 or X <27400, Y> 2700 or Y <1350). The crane control module 30 determines whether the position of the crane 80 is outside the coordinates of the restricted area. .

If the determination result is YES in step S22, then

S221: Turn off the first warning unit 50 and the second warning unit 60. When the crane 80 is outside the coordinates of the control area, the crane control module 30 turns off the first warning unit 50 and the second warning unit 60.

S222: Send a leave signal to the central server 10. Since the crane 80 has left the coordinates of the control area, the crane control module 30 sends the departure signal to the central server 10. The departure signal may include, but is not limited to, the identity (ID), operator number, operator name, crane position, weight, date and time of entering and exiting the warning area of the crane.

S223: Change the bit value of the flag register to 0. Since the crane 80 has left the coordinate of the control area, and the bit register value of the flag register in the previous time period is 1, the crane module 30 controls the bit of the flag register. The value is changed to 0.

If the judgment result in step S22 is NO, it means that the crane 80 is still located within the coordinates of the restricted area, then

S30: Waiting for the next vehicle coordinate on that day. The crane control module 30 continues to receive the crane coordinates sent by the locator module 40.
