In one possible embodiment, in order to solve the technical problem that the communication condition of the remote monitoring device configured for the elevator in the prior art is not good and the practical requirement cannot be met, a plurality of wireless signal transceiving devices 100 are configured for the remote monitoring device in the elevator system, for example, the wireless signal transceiving devices 100 are antennas, the antennas are configured at a plurality of preset positions of the elevator system, for example, in the embodiment of the present invention, the plurality of preset positions include, but are not limited to, positions inside the elevator machine room, outside the machine room, at the elevator landing, in the elevator shaft, etc., the wireless communication state information collected at each preset position is obtained through the plurality of antennas, for example, the wireless communication state information is communication state information, the communication state information is used for representing whether the wireless communication state of each wireless signal transceiving device 100 is normal or not, and the wireless signal transceiving operation is performed through the plurality of antennas, for example, to receive communication information transmitted from the communication base station or to transmit elevator monitoring data output from the remote monitoring apparatus to the communication base station.
Each of the antennas is connected to the switching device 200, for example, the antennas can be connected through a connection line with signal anti-interference capability, for example, the connection line is an optical fiber connection line, and of course, the antennas can also be connected through a wireless communication manner, which is not described in detail herein. The switching device 200 is configured to perform a corresponding transceiver switching operation according to the wireless communication state information collected by each antenna, for example, determine which antennas can perform normal wireless communication according to the communication state information, and switch the current antenna to an antenna capable of normal communication to perform a wireless signal transceiving operation when the antenna currently in use cannot perform normal communication. The switching device 200 is connected to the remote monitoring device 300, and the remote monitoring device 300 controls the wireless signal transceiver 100 to receive wireless signals from the outside or output wireless signals to the outside through the switching device 200.
For example, in one embodiment, the switching device 200 monitors whether each wireless signal transceiver 100 is in a normal communication state in real time, for example, in the embodiment of the present invention, an antenna outside the computer room is used as the wireless signal transceiver 100 for performing wireless signal transceiving operation by default, and at this time, the antenna cannot normally communicate, therefore, the switching device 200 further determines whether other antennas are communicating normally, and finds that the antenna at a landing is communicating normally, for example in the embodiment of the present invention, the communication state near the building where the elevator is located is poor, so the property has a wireless communication signal generator or a wireless communication signal enhancer arranged inside the building to provide additional communication signals for people living or working in the building, the switching device 200 thus switches the current antenna to the antenna in the landing, and the remote monitoring device 300 can control the antenna to receive or transmit wireless signals through the switching device 200.
In the embodiment of the invention, the existing remote monitoring device is improved, and the remote monitoring device is provided with the plurality of wireless signal transmitting and receiving devices 100 arranged at a plurality of positions of an elevator system, so that the remote monitoring device is allowed to select antennas capable of normally carrying out wireless communication from a plurality of positions for carrying out wireless communication, the technical problem that the remote monitoring device is only arranged in an elevator machine room or nearby the machine room and cannot effectively carry out wireless communication is effectively solved, the communication reliability and effectiveness of the remote monitoring device are improved, the effectiveness of elevator operation monitoring is improved, and the elevator riding safety is improved.
Referring to fig. 2, in the embodiment of the present invention, the wireless signal transceiver 100 includes a signal strength detection module 110 and a wireless signal transceiver module 120, and the acquiring the wireless communication status information of each preset position and performing the wireless signal transceiving operation includes: acquiring wireless signal strength information corresponding to a preset position through the signal strength detection module 110; performing the wireless signal transceiving operation by the wireless signal transceiving module 120; the switching device 200 is further configured to perform a corresponding transceiver switching operation based on the communication condition information and the wireless signal strength information.
Further, referring to fig. 3, in an embodiment of the present invention, the performing a corresponding transceiver switching operation based on the communication status information and the wireless signal strength information includes:
s21) determining an in-use transceiver device currently in use from among the plurality of wireless signal transceiver devices;
s22) primarily screening all wireless signal transceiving devices based on the communication condition information to obtain primarily selected transceiving devices;
s23) determining an optimal wireless signal transceiving device among the initially selected transceiving devices based on the wireless signal strength information;
s24) determining whether the optimal wireless signal transceiver is the transceiver in use;
s25) switching from the in-use transceiver to the optimal wireless signal transceiver when the optimal wireless signal transceiver is not the in-use transceiver.
Although the switching of the wireless signal transceiving devices 100 can be directly performed by determining the communication status information of the plurality of wireless signal transceiving devices 100, that is, it is ensured that the wireless signal transceiving devices 100 used are the wireless signal transceiving devices 100 with effective wireless communication status, in the practical application process, a plurality of wireless signal transceiving devices 100 capable of effective communication may be provided at the same time, and the received signal strength of different wireless signal transceiving devices 100 is different, for example, in an embodiment, if the currently used wireless signal transceiving device 100 is exactly the wireless signal transceiving device 100 with poor signal strength, on one hand, the communication quality of the wireless signal transceiving device 100 is poor, and the real-time performance and reliability of communication are greatly reduced; on the other hand, it also results in waste of good communication resources.
Therefore, in order to solve the above technical problem, in a possible implementation manner, the wireless signal transceiving apparatus 100 includes a signal strength detection module 110 and a wireless signal transceiving module 120, and in an embodiment of the present invention, the signal strength detection module 110 detects wireless signal strength information of a currently acquired wireless signal, and performs a wireless signal transceiving operation through the wireless signal transceiving module. In the embodiment of the present invention, the wireless communication status information includes communication status information and wireless signal strength information, the switching device 200 obtains a pre-selected transceiver after determining the wireless signal transceiver module 120 capable of performing effective wireless communication according to the communication status information, for example, after performing a preliminary screening on all the wireless signal transceivers 100 according to the communication status information, and then further determines an optimal wireless signal transceiver among the pre-selected transceivers according to the wireless signal strength information, for example, the wireless signal transceiver 100 with the highest wireless signal strength in the wireless signal strength information is used as the optimal wireless signal transceiver, at this time, it is further determined whether the antenna with the highest signal strength is the currently-used transceiver, and if so, the wireless signal transceiving operation is performed by the in-use transceiver, if not, the transceiver is switched to the optimal wireless signal transceiver from the transceiver in use to perform better wireless signal transceiving operation.
In the embodiment of the invention, the wireless communication state information of different positions of the elevator system is acquired according to the wireless signal transceiver 100, and the wireless signal transceiver 100 with the strongest communication strength is automatically switched, so that more stable and more effective wireless communication is realized, the wireless communication quality of the remote monitoring device is improved, and the reliability and the stability of the wireless communication are improved.
In the practical application process, the method can ensure that the antennas adopted by the remote monitoring device in the wireless communication process are all the antennas with the strongest signal strength, however, the signal strength of the wireless communication changes at any time, so the method can possibly cause the frequent switching of the antennas, and in the antenna switching process, the short-time signal interruption or communication abnormity of the remote monitoring device can be caused, thereby reducing the user experience and the communication stability of the remote monitoring device.
In order to solve the above technical problem, in the embodiment of the present invention, the switching device 200 is further configured to: under the condition that the optimal wireless signal transceiver is determined not to be the transceiver in use, acquiring a preset signal intensity threshold value and acquiring the current signal intensity acquired by the transceiver in use; judging whether the current signal intensity is smaller than the preset signal intensity threshold value or not; if yes, the transceiver in use is switched to the optimal wireless signal transceiver.
In a possible embodiment, after determining that the best wireless signal transceiver device with the highest signal strength is not the transceiver device in use, further acquiring a signal strength threshold and a current signal strength acquired by the transceiver device in use, and then determining whether the current signal strength is smaller than the signal strength threshold, for example, in an embodiment of the present invention, the current signal strength is greater than or equal to the signal strength threshold, that is, it may be determined that although the signal strength of the currently-used wireless signal transceiver device 100 is not the strongest, the signal strength of the currently-used wireless signal transceiver device 100 also meets a sufficient signal strength requirement, so that it is not necessary to perform a switching operation of the wireless signal transceiver device 100, and thus, the currently-used wireless signal transceiver device 100 is used to perform a wireless signal transceiving operation.
In another possible embodiment, the switching device 200 may also monitor the signal strength of the transceiver device currently in use in real time, and only when the signal strength of the transceiver device in use is lower than the preset signal threshold, further acquire the wireless signal strength information of other wireless signal transceiver devices 100, determine and switch to the optimal wireless signal transceiver device with the highest signal strength to continue the wireless signal transceiving operation, thereby further reducing the amount of computation, increasing the response speed of the switching device 200, and reducing the switching frequency of the switching device 200.
In the embodiment of the present invention, in the process of comparing the signal strength of the wireless signal transceiver 100, it is further determined whether the signal strength of the transceiver currently in use is lower than a preset signal strength threshold, and when the signal strength of the transceiver in use meets the use requirement, the switching operation of the wireless signal transceiver 100 is not performed, so that the switching frequency of the wireless signal transceiver 100 is greatly reduced, and the stability and reliability of the wireless communication of the remote monitoring device are improved.
Further, in the practical application process, the technicians notice that although the reliability and effectiveness of the wireless communication of the remote monitoring device can be effectively improved by using the wireless signal transceiver 100 with the highest wireless signal strength to transmit and receive the wireless signal, for an area with a large traffic volume, such as a shopping mall, the occurrence of communication congestion in the wireless communication in the area is caused by too many people in one area, and even if the wireless signal strength in the area is high, the occurrence of poor wireless communication quality, such as communication jamming, high communication delay, small communication bandwidth and the like, can still be caused, so that the communication reliability and real-time performance of the remote monitoring device are reduced.
In order to solve the above technical problem, referring to fig. 4, in an embodiment of the present invention, the wireless communication system further includes a reliability evaluation device 400, the reliability evaluation device 400 is connected to each wireless signal transceiver 100, and the reliability evaluation device 400 includes: a test module 410, connected to each wireless signal transceiver 100, for sending test information to each wireless signal transceiver and obtaining corresponding feedback information; a reliability evaluation module 420, connected to the test module 410 and the switching device 200, for evaluating the communication reliability of the corresponding wireless signal transceiver 100 based on the feedback information, and generating a corresponding evaluation result; the switching device 200 determines the best wireless signal transceiver among the initially selected transceivers based on the wireless signal strength information, including: extracting the maximum wireless signal intensity from the wireless signal intensity information corresponding to the primarily selected transceiver, and taking the wireless signal transceiver corresponding to the maximum wireless signal intensity as the optimal wireless signal transceiver; or executing sorting operation on the wireless signal strength information corresponding to the initially selected transceiver to obtain sorted information; optimizing the sorted information based on the evaluation result to obtain optimized information; and determining the optimal wireless signal transceiving device based on the optimized information.
In a possible implementation, a reliability evaluation apparatus 400 is further configured in the wireless communication system, the reliability evaluation apparatus 400 includes a test module 410 and a reliability evaluation module 420, the test module 410 is connected to each wireless signal transceiver apparatus 100, during the practical application, the test module 410 may send test information to the wireless signal transceiver apparatus 100 according to a preset test frequency or test period, for example, the test information is a test frame sent to a cloud server through the wireless signal transceiver apparatus 100, the cloud server immediately feeds back a corresponding response frame (feedback information) after receiving the test frame, the reliability evaluation module 420 calculates the communication reliability of the wireless signal transceiver apparatus 100 through the response frame immediately after receiving the response frame, for example, calculates the communication delay through the response time, calculates the data congestion condition through the data transmission speed, and the like, and generates a corresponding evaluation result, for example, the evaluation result is used to characterize the wireless communication quality of the wireless signal transceiver 100.
After acquiring the wireless signal strength information of each wireless signal transceiver 100, the switching device 200 may first perform a sorting operation on the wireless signal strength information corresponding to the initially selected transceiver, for example, sort the wireless signal strength information in an order from high to low, and then optimize the sorted information according to the evaluation result, for example, convert the evaluation result into an optimization factor, and multiply each wireless signal strength by its corresponding optimization factor to obtain optimized information, at this time, determine the wireless signal transceiver corresponding to the information with the largest value of the optimized information as the optimal wireless signal transceiver.
In the embodiment of the invention, the communication condition of the wireless signal transceiver 100 is comprehensively calculated from different dimensions of the wireless signal transceiver 100 and the optimal wireless signal transceiver is determined, so that the communication quality of the remote monitoring device can be further optimized on the basis of effectively realizing the normal communication of the remote monitoring device, the communication stability, the reliability and the real-time performance of the remote monitoring device are improved, the monitoring accuracy of an elevator is improved, and the use safety of the elevator is improved.
