It is a figure which shows the flow of the maintenance work of the maintenance worker managed by the system of FIG. It is a figure which shows the measurement flow of brake braking distance measurement.

  An elevator maintenance work management system according to an embodiment of the present invention will be described.

  FIG. 1 shows an overall configuration diagram of a maintenance work management system.

  This system is a part of the information processing terminal 1 or is detachably connected to the information processing terminal 1, and includes a sensor 11 for measuring the state of the elevator, a work schedule and work contents of maintenance personnel. And a memory 12 for storing the measurement result in the inspection, a signal processing input from the sensor, a calculation unit 13 for judging pass / fail from the measurement result, a measurement result is transmitted to the outside, and a previous measurement result is externally transmitted. The information processing terminal 1 is equipped with communication units 14a and 14b that receive information, and is portable and performs work management and inspection measurement of maintenance personnel, an elevator 2 that includes a control panel 21, and driving information and monitoring from the elevator 2. The memory 31 for storing the status and the operation information obtained from the control panel 21 are extracted from the memory 31 and calculated, and recorded in the memory 31 as monitoring information. A monitoring unit 3 including a calculation unit 32 for processing, a communication unit 33a, 33b for transmitting a measurement result to the outside, and receiving a previous measurement result from the outside, and monitoring information accumulated in the monitoring device 3 periodically. To the control center 5 and when the elevator 2 breaks down or the passengers are trapped, the telephone line 4 is a line for immediately reporting to the outside, and the monitoring device 3 periodically sends it. A control center 5 having a server 51 for storing data collectively, an in-house network line 6 for transmitting / receiving data accumulated in the server 5, an inspection schedule of an inspector, a work report after the inspection, etc. to each base 61; It is made up of.

  FIG. 2 shows a flow of maintenance work of maintenance personnel managed by the system of FIG. Before going to the inspection site, the maintenance staff connects the information processing terminal 1 to the in-house network line 6 at his / her base 61 (step Sll), receives the work schedule of the day from the control center 5 and stores it in the memory 12. (Step S12). The inspection items are preliminarily determined in advance, and the contents of maintenance work are instructed by the schedule received by the maintenance staff. The maintenance staff carries the information processing terminal 1 that has taken in the schedule, goes to the site (step S13), and performs inspection / maintenance work according to the schedule that is taken into the information processing terminal 1 (step 14). If various measurement items are specified in the inspection items in the schedule, various inspections and measurements are performed using the information processing terminal 1. In the present embodiment, the measurement is performed by temporarily attaching a sensor to the elevator, such as measurement of brake operating characteristics and braking distance, and operating the elevator in a special measurement mode different from normal. This refers to measurement that cannot be performed by the monitoring device 3 or is not performed. When the inspection / maintenance work is completed, the maintenance worker inputs the work result of the day to the information processing terminal 1 and stores it in the memory 12, and returns to his / her base 61 (step S15). After returning to his / her base 61, the maintenance staff connects the information processing terminal 1 to the in-house network 6 (step S16), and transmits the work result of the day to the server 51 of the control center 5 (step S17).

  FIG. 3 shows a measurement flow for measuring a brake braking distance, which is an example of a measurement item. In the braking distance measurement, the car is first stopped at the lowest floor (step S21), and an operation mode for measuring the braking distance is set (step S22). Next, the vehicle is lifted (UP) at a constant speed from the lowest floor in a no-load state (step S23). Under the braking distance measurement mode, the speed is about 45 m / min, and the buzzer sounds when a predetermined position near the top floor is reached (step S25). While this buzzer is sounding, the maintenance person artificially stops the emergency stop such as forcibly opening the lower floor hold door (step S26). The elevator control panel 21 measures the braking distance at this time and stores it in the memory (step S27). Whether this braking distance is appropriate is determined by the calculation formula including the specifications of each elevator, that is, the lift and car capacity (maximum carrying weight), speed, and the coefficient determined by the type of brake used. It is determined based on the magnitude of A (step S28), the previous determination value A ′ obtained from the braking distance measured a certain period before about one year ago, and the amount of change in the current determination value A. When the information processing terminal 1 reads the braking distance from the control panel 21 and calculates the determination value A this time, the information processing terminal 1 is connected to the monitoring device 3. The memory 31 of the monitoring device 3 stores the previous measurement result including at least the previous measurement date and the determination value A ′, and the information processing terminal 1 reads this value from the monitoring device 3 to obtain the current determination value and Comparison is made (step S29), and the quality of the brake braking distance is determined (step S30). Further, the current measurement result including at least the current measurement date and the determination value is transmitted from the information processing terminal 1 to the monitoring device 3 and stored in the memory 31 of the monitoring device 3.

  By doing so, it is not necessary to store the current measurement result in the information processing terminal 1, and it is not necessary to leave the previous measurement result in the information processing terminal 1 and leave for the site.

  Further, even when the monitoring device 3 is failed and replaced, the previous measurement value can be taken from the control center 5. As a result, it is not necessary to leave customer data in the information processing terminal 1, which is effective in terms of security.

  In addition, even when maintenance work other than the scheduled work person is working, when measurement work is necessary outside the plan, the work can be performed on-site without acquiring the previous measurement result.
