In the embodiment of the present invention, the output value of the initial current called outside the lattice is: the current output value detected when the lattice leaves the factory is called out; or a preset initial current output value.
In a possible implementation mode, after the elevator is installed on the site and debugged, technicians perform power-on initialization operation on the elevator, at the moment, the elevator control system controls the elevator to call out to perform full-bright operation, records the initial current output value of each call out of the elevator at the moment, and stores the initial current output value in the elevator control system, or sends the initial current output value of each call out of the elevator to the cloud server for storage in a wired or wireless communication mode.
In another possible implementation manner, the initial current output value called outside the lattice may also be an initial current output value based on big data acquired from a cloud server, and the elevator control system stores the initial current output value in the local storage device after acquiring the initial current output value.
In an embodiment of the present invention, the sampling condition includes a sampling period and a sampling time, and the acquiring an actual current output value called outside the dot matrix under the sampling condition includes: acquiring the previous sampling time of the previous sampling, and judging whether the time difference between the current sampling time and the previous sampling time reaches the sampling period; under the condition that the time difference reaches the sampling period, judging whether the current time is the sampling time; and under the condition that the current moment is the sampling moment, driving the dot matrix external call to be in a full-bright state, and collecting an actual current output value of the dot matrix external call.
In a possible implementation manner, after the initialization is completed, the elevator starts to operate normally, the elevator control system records the current time in real time, compares the current time with the time of the previous sampling, and judges whether the time difference between the current time and the previous sampling time reaches a sampling period, for example, in the embodiment of the present invention, the sampling period is 30 days, and when the time difference reaches the sampling period, further judges whether the current time is the sampling time, for example, the elevator control system obtains the sampling time of 1:00-5:00 in the morning, and the current time of 8:31 in the evening, which is not in the time range of the sampling time, so that the normal use of the elevator is continuously maintained. When the time reaches the sampling moment, the elevator control system drives all external calls of the elevator to be in a full-bright state, and collects the actual current output values of all the external calls of the elevator at the moment.
In the embodiment of the present invention, the sampling period may be adjusted according to actual situations, for example, the sampling period of 30 days may be set in the 1 st to 3 rd years used in the external calling of the dot matrix, the sampling period of 15 days may be set in the 3 rd to 5 th years used in the external calling of the dot matrix, and the sampling period of 1 to 7 days may be set in the years above 5 years used in the external calling of the dot matrix.

In an embodiment of the present invention, the acquiring the dead pixel called outside the dot matrix includes: dividing a display area called outside the dot matrix into a plurality of debugging areas, wherein each debugging area comprises a plurality of display units; sequentially driving each debugging area in the plurality of debugging areas to be in a full-bright state; sequentially acquiring a debugging current output value of each debugging area, judging whether the debugging current output value of each debugging area is in a normal range, sequentially lightening each display unit in the debugging area for the debugging area with the debugging current output value not in the normal range, and acquiring an individual current output value of each display unit; and judging whether the display unit corresponding to the single current output value normally displays or not based on the single current output value, and determining that the display unit is a dead pixel called outside the dot matrix under the condition that the display unit does not normally display.
In a possible implementation manner, the LED dot matrix called outside by 7 × 11 is called outside by the dot matrix of the elevator, the elevator control system detects that the actual current output value called outside by a certain dot matrix of the elevator is 160mA in the process of detecting the current output value called outside by the dot matrix, and at this time, the elevator control system obtains that the initial current output value called outside by the dot matrix is 168mA, that is, the actual current output value called outside by the dot matrix is smaller than the initial current output value, so that it is determined that the actual current output value called outside by the dot matrix does not satisfy the preset output condition.
It should be noted that, since the current value of the normal output may change in a small range due to the use time, the ambient temperature, the ambient noise, and the like during the use process, the deviation range of the current output value may also be set according to the actual situation, for example, the deviation range is ± 10mA, that is, when the actual current output value is within the range of ± 10mA of the initial current output value, it is determined that the preset output condition is satisfied. The deviation range is set for the current output value according to actual conditions, so that the frequent alarm phenomenon caused by fluctuation of output current is effectively avoided, and technical personnel do not need to frequently go to the site to perform fault treatment, so that the accuracy of elevator lattice calling detection is improved, the maintenance cost of enterprises is reduced, and the working efficiency of the technical personnel is improved.
Further, in the embodiment of the present invention, the elevator control system sets each horizontal row called outside the dot matrix as one debugging region, so that 7 debugging regions called outside the dot matrix are obtained, where each debugging region includes 11 LED display units, at this time, the elevator control system sequentially drives each debugging region in the 7 debugging regions to be in a full-bright state, and obtains a debugging current output value of each debugging region, for example, the debugging current output values of the 1 st to 7 th debugging regions are respectively: 24mA, 20mA, 24mA, 18mA, 24mA, find that the debugging current output value in 3 rd debugging region and 6 th debugging region is not in normal range, at this moment elevator control system independently lights each display element of 3 rd debugging region and 6 th debugging region in proper order, for example the LED lamp, and obtains the individual current output value of each display element, find that 1 st, 2 nd LED lamp in 3 rd debugging region and 5 th-7 th LED lamp in 6 th debugging region are not normally displayed, therefore confirm above-mentioned LED lamp as the bad point that this dot matrix calls out.
In the embodiment of the invention, the output value of the initial current called outside the dot matrix is recorded when the dot matrix is used for the first time, and the detection is carried out on the dot matrix for one time in each acquisition period in the subsequent use process, so that whether the dot matrix is called outside the dot matrix to have a dead pixel or not is detected in time, the adjustment or alarm prompt can be carried out on the dot matrix called outside the dead pixel in time, the normal use of a user is ensured, and the detection effectiveness is improved. Furthermore, the detection of the external calling of the dot matrix can be finished under the condition of the fastest speed by means of a comprehensive detection mode and a local detection mode, the detection efficiency is improved, the interference caused by long-time detection to normal use of a user is avoided, meanwhile, each dead pixel called by the external calling of the dot matrix can be accurately detected, the detection accuracy is greatly improved, more accurate data support is provided for generating accurate adjustment operation or alarm prompt operation in the follow-up process, the conditions that technicians frequently work out or frequently adjust display contents and the like caused by misinformation or misoperation are avoided, the user experience is improved, and the enterprise operation cost is reduced.

In a possible implementation manner, after a dead pixel called outside the current dot matrix is obtained, the position information of the dead pixel is obtained according to the arrangement information of the dead pixel, at the moment, the elevator control system further obtains a damaged area called outside the dot matrix, for example, a common display area or a necessary display area called outside the dot matrix is set as the damaged area, the elevator control system judges whether the dead pixel is in the damaged area, and if the dead pixel is in the damaged area, the damaged monitoring information called outside the dot matrix is generated; if the dead pixel is not in the damaged area, adjusting the display area called outside the current dot matrix according to the position information of the dead pixel, for example, reducing the display area called outside the dot matrix, so as to completely display the current information called outside the elevator under the condition of avoiding the dead pixel, and simultaneously generating the monitoring information which needs to be overhauled and called outside the dot matrix.
Furthermore, in the embodiment of the invention, in order to ensure that the monitoring information called outside the dot matrix can be more effectively obtained by the technical staff in time and reduce the maintenance cost of the enterprise, after the monitoring information called outside the dot matrix is generated, the monitoring information can be sent to the cloud server in real time in a wired or wireless communication mode, and the monitoring information is notified to the corresponding technical staff through the cloud server.
In the embodiment of the invention, different adjustment or alarm operation is adopted according to the position information of the dead pixel, so that the normal use of a user can be ensured to the maximum extent, meanwhile, the abnormal condition of calling out the dot matrix of the elevator can be monitored in time, and when the abnormal condition does not belong to the emergency condition, a technician can reasonably arrange the working time, thereby greatly reducing the unreasonable working of the technician, improving the working efficiency of the technician, reducing the operation and maintenance cost of enterprises and improving the user experience.
