Detailed Description

The invention is further described with reference to the drawings and the specific embodiments.

Data outward transmission interface is generally reserved in current elevator control panel so that elevator manufacturers debug, but the data outward transmission interface of the elevator control panel that the elevator manufacturers of difference adopted is different, and some adoption CAN, some adoption USB and some adoption 485 serial ports. Because the data outgoing interfaces are all unidirectional, the data are read through the data outgoing interfaces, and the safe operation of the elevator is not influenced. Of course, different manufacturers have different communication protocols, and therefore, reading these data by external devices is generally used for recording and analysis, and the specific contents outputted by the elevator control panel cannot be directly obtained from these data without knowing their specific communication protocols.

Referring to fig. 1, the present embodiment discloses an elevator state monitoring apparatus, including:

the circuit board comprises a PCB body and a circuit printed on the PCB body.

A processor disposed on the circuit board, the processor provided with a plurality of communication interfaces; the communication interface includes a serial interface, a USB interface, a network interface, and the like.

An acceleration gyroscope disposed on the circuit board and in communication with the processor; the acceleration gyroscope is used for acquiring data such as the running speed of the elevator. Wherein the sensor is the sensor necessary to monitor the state of the elevator.

The data transmission module is arranged on the circuit board and is communicated with the processor, and the data transmission module is used for transmitting data to equipment outside the device; the data transmission module is mainly used for transmitting the data of the elevator to equipment such as a server and the like for centralized analysis, wherein the transmitted data comprises the data collected by the sensor of the device and the data read from the elevator control panel.

At least two wired communication modules arranged on the circuit board, wherein each wired communication module is used for providing a signal conversion function for the communication interface; in this embodiment, since the type and the operating voltage of the data outbound interface selected by the elevator control board are uncertain, it is necessary to perform protocol and level conversion on a part of the communication interfaces through the wired communication module. For example, the elevator control panel adopts an RS485 serial port, and although the processor is also provided with a serial port, direct communication cannot be performed due to voltage mismatching, at this time, conversion needs to be performed through an RS485 conversion chip, and in this example, the RS485 conversion chip and peripheral circuits thereof constitute the wired communication module.

And the wiring terminals lead out the communication lines of the wired communication module and/or the communication lines of the communication interface. In this embodiment, the size of the plug and the socket of the communication interface, such as RS485 and RS232, is large, which increases the size of the solution. Therefore, the communication line of the communication interface or the communication module is led out by the wiring terminal, so that the size of the scheme is reduced, and meanwhile, the wire rod is compatible with different wires.

The operating principle of this embodiment is, with this device and elevator car together fixed, gather the speed data of operation of elevator by the acceleration gyroscope, and this device passes through the data of one of them wired communication module and elevator control panel and passes interface connection outward to acquire the data of elevator control panel output. The processor of the device processes the data after receiving the data uploaded through different data interfaces, for example, processes the data according to a certain communication protocol, and sends the processed data out through the data sending module. As for the direct object transmitted by the data transmission module, it may be a device such as a base station, a gateway, a router, a server, etc., and the data is finally concentrated on the server for data processing.

Referring to fig. 2, the present embodiment discloses an elevator state monitoring apparatus, wherein the apparatus includes a circuit board 210, and a plurality of sets of connection terminals including a first set of connection terminals 221, a second set of connection terminals 222, a third set of connection terminals 223, a fourth set of connection terminals 224, and a fifth set of connection terminals 225. Each group of the connecting terminals is provided with more than two connecting units. The object to which the first group of connection terminals 221 is connected is a CAN unit 231, and the CAN unit 231 is used for protocol conversion and/or level conversion. Therefore, when the data transmission interface of the elevator control panel adopts the CAN interface, the data transmission interface CAN be accessed through the first set of connection terminals 221, and the CAN unit 231 processes the input signal and outputs the processed signal to the MCU unit 240. Similarly, when the data transmission interface of the elevator control panel adopts an RS232 interface, the data transmission interface can be accessed through the second group of connection terminals 222, and the RS232 unit 232 processes the input signal and outputs the processed signal to the MCU unit 240. When the data external transmission interface of the elevator control panel adopts an RS485 interface, the data external transmission interface can be accessed through the third group of wiring terminals 223, and the RS485 unit 233 processes the input signal and then outputs the processed signal to the MCU unit 240. As for the fourth set of connection terminals 224, in this embodiment, these connection terminals are equivalent to being directly connected to the communication interface of the MCU unit 240, and no wired communication module capable of implementing level and protocol conversion is used, so when selecting a sensor connected through the fourth set of connection terminals 224, it is necessary to pay attention to whether the output interface type of the sensor matches the communication interface type of the MCU unit 240. In this embodiment, since the number of the wiring units of the fourth set of wiring terminals 224 is large, multiple sets of sensors can be connected simultaneously, but the MCU unit 240 does not have such many communication interfaces, the gating switch 270 can be arranged to multiplex the plurality of sensors connected to the fourth set of wiring terminals 224 into a communication interface in a time-sharing manner. Such as temperature and humidity sensors, it is not necessary to collect data every moment, so that a scheme of time-division multiplexing the communication interface is feasible. In time division multiplexing, the state of the gate switch 270 is controlled by the MCU unit 240 as appropriate. Of course, in this embodiment, the data transmission module is further included, which is an NB-IOT module 250 in this embodiment, and the MCU unit 240 transmits the processed data to the NB-IOT module 250 through a communication interface such as a serial port, and transmits the data to an external receiving device through the NB-IOT module 250. Of course, the MCU unit 240 includes elevator operation data collected by the acceleration gyro 280 in addition to data of the elevator control board.

Because elevator car reciprocates, consequently, this device is higher through the direct degree of difficulty of getting the electricity of elevator line, directly gets the electricity through the elevator line moreover and influences elevator safe operation easily. Therefore, the device takes electricity through the elevator control panel, and the voltage of the elevator control panel is usually 24V direct current. Therefore, the device needs a power supply module to convert the voltage so that the processor can operate normally. Meanwhile, an emergency such as power failure occurs occasionally, and therefore, in order to ensure that the device can operate normally when power failure occurs, the power supply module is usually provided with a battery and a charging circuit.
