Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. Wherein, in this embodiment, the so-called "escalator" cannot be interpreted in a narrow sense, and track-type automatic conveying systems such as escalators or moving walks are collectively referred to as escalators.

Fig. 1 schematically shows a functional block diagram of a preferred embodiment of the present invention, as shown in the figure, the escalator running record monitoring device of this preferred embodiment includes a data processor 1 and a display module 11 connected thereto, a communication module 12, as The transformer 13 of the current and voltage acquisition module, the alarm module 14, the I/O isolation module 15 and the running speed detection module 21, the running direction detection module 22, and the brake detection module 23 connected to the data processor 1 via the I/O isolation module 15 , the inspection panel switch monitoring module 24 , and the safety loop monitoring module 25 .

In this preferred embodiment, the data processor 1 is an ARM. Of course, the present invention is not limited thereto, and various integrated circuits with data processing capabilities are applicable here, such as single-chip microcomputers, FPGAs, DSPs, and even ASICs. Signals can be transmitted between the functional modules through a wired connection or a wireless connection. The data processor 1 can obtain all kinds of standard operating data of the escalator from the control device of the escalator, including the instruction signal of the escalator control device to the escalator, etc., and perform data processing,

Among them, the transformer 13 is used to collect the actual current and actual voltage of the escalator system. The running speed detection module 21 is used to detect the actual running speed of the escalator. The running direction detection module 22 is used to detect the actual running direction of the escalator. The brake detection module 23 is used to detect the action of the brake of the escalator. The access panel switch monitoring module 24 is used to detect the opening action of the access panel of the escalator. The safety circuit monitoring module 25 is used to detect the safety circuit system composed of circuit switches in the escalator.

In order to understand the operating status of the escalator in real time, and to issue an early warning when a failure may occur, and upload the operating parameters of the escalator or receive instructions from the host computer, the data processor 1 of the preferred embodiment is also connected with a display module 11, an alarm module 14, communication module 12.

Next, the function and working principle of each component in the escalator running record monitoring device of the present invention will be described in detail.

The data processor 1 can be used to obtain the standard operating voltage, standard operating current and standard operating power of the escalator from the escalator control device, and compare it with the actual current, actual voltage and calculated actual operating power detected by the transformer 13. When the difference exceeds When setting the threshold, the data processor 1 drives the alarm module 14 to issue an alarm, and makes the display module 11 display abnormal parameters.

For example, the data processor 1 obtains the standard operating voltage _U , the standard operating current I and _the standard operating power _P indicated by the control device of the escalator itself, and collects the actual current signal I _and voltage signal U of the escalator system through the transformer 13. _Real , and then through the internal calculation of the actual operating power P _real . If the current is taken as an example, when the difference _{between Iactual} and _Imark exceeds a certain value, for example, when the value exceeds ±5% of the standard operating current _Imark , the data processor 1 generates an alarm signal and transmits the signal to the alarm module 14 to give an alarm, and at the same time, the data processor 1 controls the display module 11 to display the abnormal situation of the current.

Wherein, the display module 11 may be a light flashing warning device composed of display lights of various colors, or a display device such as a display screen, which displays corresponding information through icons or text. The alarm module 14 can issue an alarm to the user by issuing sounds such as voice, buzzer, musical tone or other methods.

In addition, when the _actual current signal I and the voltage signal U collected by the transformer 13 _are too weak, for example, less than the preset value of 5% or 10% _of the standard operating _current I and the standard operating voltage U, It can be judged that the escalator has a power failure, and then a power failure alarm will be issued.

In addition, the communication module 12 is connected with the data processor 1 for data interaction between the data processor 1 and external equipment, for example, the data processor 1 transmits the relevant data processed by it to the peripheral data storage device through the communication module 12 To save, as a peripheral data storage device, it can be a hard disk, a U disk, etc. Therefore, it is possible to record various data and the like collected by modules such as transformers and related data obtained after processing the collected various data and the like.

This preferred embodiment can also monitor the running speed and running direction of the escalator, and when the escalator reverses or the escalator overspeeds or stalls, an alarm signal can be sent.

The data processor 1 is connected with the running speed detection module 21 via the I/O isolation module 15, and obtains the standard running speed of the escalator from the control device of the escalator itself, and compares it with the actual speed detected by the running speed detection module 21, and when the difference exceeds When setting the threshold, the data processor 1 drives the alarm module 14 to issue an alarm, and makes the display module 11 display abnormal parameters.

Specifically, the data processor 1 acquires the standard running speed (the speed is a scalar, not a vector) V _scalar indicated by the escalator control device, and obtains the actual running speed V _real of the escalator through the running speed detection module 21 . When the actual running speed V _actually exceeds or falls below a certain set value within 5% to 10% _of the standard running speed V (can be set according to different escalator models, such as 6%, 7% or 8.5%), The data processor 1 transmits a signal indicating that the running speed of the escalator is overspeed or too low to the alarm module 14 for an alarm. At the same time, the data processor 1 controls the status display module 11 to display the abnormal situation of the running speed.

Furthermore, the data processor 1 is connected to the running direction detection module 22 via the I/O isolation module 15 . The data processor 1 acquires information on whether there is an upward running command or a downward running command of the escalator from the control device of the escalator. After obtaining the escalator running command, it is compared with the actual running direction detected by the running direction detection module 22. When the running command is inconsistent with the actual running direction of the escalator, the data processor 1 drives the alarm module 14 to issue an alarm, and makes the display module 11 display Abnormal running direction.

Specifically, as shown in FIG. 3 , the running direction detection device 22 of this preferred embodiment has an upstream sensor 51 and a downstream sensor 52 arranged outside the rotating disk 4 at the end of the escalator traction machine. The upstream sensor 51 and the downstream sensor 52 are arranged at a predetermined interval from the rotating disk 4 . The rotating disk at the end of the traction machine runs synchronously with the escalator motor, and its rotation direction (arrow direction as shown in Figure 3) indicates the running direction of the escalator. At least one induction hole 41 is provided on the rotating disc 4 at the end of the traction machine. The upstream sensor 51 is located upstream of the general operating state of the end rotating disk 4 of the traction machine, and the downstream sensor 52 is located downstream of the general operating state of the end rotating disk 4 of the traction machine. The upstream sensor 51 and the downstream sensor 52 respectively detect the sensing hole 41 and generate pulse signals 31 and 32 as shown in FIG. 2 . The rising edge represents the detection of the sensing hole 41, as shown in Figure 2, the time point when the downstream sensor 52 detects the sensing hole 41 lags behind the time point when the upstream sensor 51 detects the sensing hole 41, indicating that the escalator is running upwards state. Conversely, if the upstream sensor 51 detects the sensing hole 41 later than the downstream sensor 52, it means that the escalator is in a downward running state. That is, it is judged that the escalator is in an upward running state or a downward running state according to the time relationship between the upstream sensor and the downstream sensor detecting the sensing hole. The pulse signals detected by the upstream and downstream sensors are sent to the data processor 1 respectively, so that the data processor 1 obtains the actual running direction of the escalator.

And, data processor 1 obtains the escalator running command from the escalator control device, if the escalator running command acquired is an upward running command, and detects that the escalator is in a downward running state, then data processor 1 drives the alarm module 14 to issue an alarm, and The display module 11 displays the situation that the running state is abnormal, that is, the escalator reverses. And, if the acquired escalator operation instruction is a downward operation instruction, and it is detected that the escalator is in an upward movement state, similarly, the data processor 1 drives the alarm module 14 to issue an alarm, and the display module 11 displays that the operation state is abnormal, that is, the escalator is reversed. . Among them, when the data processor 1 does not obtain the escalator operation command, that is, the escalator control device does not instruct the escalator to run, and the escalator should be in the stop state, but when it detects that the escalator is in the upward or downward running state, the data processor 1 also drives the alarm module 14 sends out an alarm, and displays the situation that the operation status is abnormal, that is, there is no command operation, at the display module 11.

In addition, the data processor 1 of this preferred embodiment is also connected to the brake detection module 23 via the I/O isolation module 15, and is used to obtain the brake command signal from the escalator control device, and combine the brake command signal with the brake detected by the brake detection module 23. Comparing the action signals, if the instruction signal is inconsistent with the action of the brake, the data processor 1 drives the alarm module 14 to issue an alarm, and makes the display module 11 display that the brake is abnormal. For example, when the data processor 1 monitors the brake release instruction signal of the escalator control device to the escalator, but the brake detection module 23 does not detect the brake release action, that is, when there is no brake release action signal, the data processor 1 can use it accordingly. It is determined that the brake does not act according to the instructions of the escalator control device, and there is an abnormal brake braking state, so the alarm module 14 can be driven to issue an alarm, and the display module 11 can display that the brake is abnormal.

The data processor 1 of this preferred embodiment is also connected to the access panel switch monitoring module 24 via the I/O isolation module 15, and each time the access panel is opened, the access panel switch monitoring module 24 detects the opening action of the access panel to obtain the access panel The opening signal of the inspection panel switch monitoring module 24 transmits the pulse signal representing the opening of the inspection panel to the data processor 1, and the data processor 1 accumulates and counts the number of inspections, and records the generation time and/or On duration. Thereby, the previous maintenance history of the escalator can be recorded.

The data processor 1 is also connected with the safety loop monitoring module 25 via the I/O isolation module 15, and the safety loop monitoring module 25 monitors the safety loop system formed by the switches of the circuits in the escalator, and passes the obtained monitoring signal to the data processor 1. When the electrical signal in the safety loop system is abnormal, the monitoring signal transmitted to the data processor 1 will reflect the abnormality and be judged by the data processor 1, thereby driving the alarm module 14 to issue an alarm to warn maintenance personnel to detect the safety loop system. The safety circuit monitoring module 25 can be connected in parallel with the safety circuit system composed of switches in the escalator, but it is not limited thereto, as long as it can detect abnormal signals of the safety circuit system. When the electrical signal in the safety loop system is abnormal, the electrical signal of the safety loop monitoring module 25 is abnormal. For example, if it is the disconnection of the safety circuit that causes the abnormality, the pulse signal detected by the safety circuit monitoring module 25 is sent to the data processor 1, and will reflect the disconnection of the safety circuit, so that the data processor 1 drives the alarm module 14 Send out an alarm signal. Wherein, the above-mentioned safety loop system may be a loop system formed by connecting all circuit switches in the escalator, or may be a loop system formed by circuits requiring key monitoring, such as some pre-designated circuit switches.

To sum up, the escalator operation record monitoring device of the present invention can comprehensively and completely obtain various operation signals of the escalator and detect various information in the actual operation state of the escalator, thereby comprehensively and accurately obtaining the operation condition of the escalator, satisfying the conditions of state monitoring, The need for failure analysis. For example, by obtaining the built-in standard operating voltage and current signal of the escalator and comparing it with the collected actual voltage and current signal during actual operation, it is possible to determine whether the voltage and current of the escalator is abnormal. Furthermore, by obtaining the standard running speed of the escalator and comparing it with the detected actual speed, it is possible to determine whether the speed of the escalator is overspeed or stalled. In addition, the running direction command can be obtained and compared with the actual running direction to determine whether the escalator is reversed. Furthermore, according to the escalator running record monitoring device of the present invention, it can also judge the working state of the brake, record the previous maintenance history of the escalator, and monitor the safety loop system composed of the circuit switches in the escalator.

It can be known from common technical knowledge that the present invention can be realized through other embodiments without departing from its spirit or essential features. Accordingly, the above-disclosed embodiments are, in all respects, illustrative and not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are embraced by the present invention.
