Description

A kind of semaphore Current Voltage analog quantity transmitting device
Technical field
The utility model belongs to the traffic signal control system technology of intelligent transportation field, and in particular to a kind of signal is electromechanical Flow voltage analog transmitting device.
Background technology
Traditional semaphore is not comprehensive enough to the detection of various electrical parameters, and is typically only the digital quantity for judging whether to whether there is Form is unfavorable for carrying out more detailed Study on Problems to the failures such as semaphore itself and signal lamp, control circuit;If newly-increased phase The whistle control system fault detection module answered, general wiring is more complicated, moreover newly-increased detection device is also not easy to transmit Information to platform carries out big data comparative analysis, and data management is more single.
Utility model content
The purpose of this utility model is to provide a kind of semaphore Current Voltage analog quantity transmitting devices, realize to signal control The electric current of system processed, voltage analog detection, while can be realized by 4G wireless way for transmitting to enterprise backend to semaphore Precision management and big data analysis.
To achieve the above object, the utility model employs following technical scheme:Including microcontroller and Current Voltage mould Analog quantity detection circuit, the Current Voltage analog quantity detection circuit are connect by interface circuit with semaphore, signal lamp respectively, institute It states microcontroller to connect with O&M backstage by 4G wireless transport modules, which simultaneously passes through CAN conversion circuits and signal The CAN interface connection of machine.
As a further improvement of the above technical scheme:
The Current Voltage analog quantity detection circuit includes multiple detection chips being connect with microcontroller, the detection core Piece is connected respectively by current converter circuit, voltage conversion circuit and signal lamp, semaphore.
The microcontroller uses the chip of model ESM3352.
The model HT7038 of the detection chip.
The current converter circuit uses the current transformer of model ZEMCT131, and voltage conversion circuit uses model The voltage transformer of ZMPT107.
As shown from the above technical solution, the utility model is detected by Current Voltage analog quantity and 4G transmitting devices are set Meter, realizes under the premise of original signal machine software and hardware function is constant, to the reality of whistle control system electric current, voltage analog magnitude When detect, and then the working conditions such as practical light on and off that can determine whether out signal lamp, further pass through the semaphore real-time status of acquisition Information carries out real-time judge to its working condition, and detailed positioning analysis is carried out to existing fault message.Pass through integrated 4G The related operation information and fault message of semaphore can be uploaded to O&M backstage in time, improve failure by wireless transport module The accuracy of analysis, real-time, and available for the big data analysis of later stage crossing relevant information.The device is using convenient, intelligence It is higher to change level, can be widely applied in current whistle control system.
Description of the drawings
Fig. 1 is the circuit block diagram of the utility model;
Fig. 2 is the circuit block diagram of the Current Voltage analog quantity detection circuit of the utility model.
Specific embodiment
The utility model is described further below in conjunction with the accompanying drawings:
As shown in Figure 1, the semaphore Current Voltage analog quantity transmitting device of the present embodiment, including microcontroller 1 and electric current Voltage analog detection circuit 2, Current Voltage analog quantity detection circuit 2 by interface circuit 7 respectively with semaphore 4, signal lamp 5 Connection, microcontroller 1 are connect by 4G wireless transport modules 3 with O&M backstage, which simultaneously passes through CAN conversion circuits 6 It is connect with the CAN interface of semaphore 4.
The Current Voltage analog quantity detection circuit 2 includes multiple detection chips 21 being connect with microcontroller 1, detection chip 21 are connect respectively by current converter circuit 22, voltage conversion circuit 23 with signal lamp 5, semaphore 4.The microcontroller 1 uses The chip of model ESM3352, to meet the hardware capability need of the devices such as network interface, 4G coffrets, CAN interface, SPI interface It asks.
In the present embodiment, for the detection chip 21 using the HT7038 electric parameter detection chips of SPI communication, detection chip 21 can 3 road alternating voltage input of detection simultaneously and 3 road alternating current inputs, and pass through SPI communication and be sent to micro controller, meanwhile, detection Chip 21 can detect way according to signal lamp and be extended.Current converter circuit 22 uses the Current Mutual Inductance of model ZEMCT131 Device is, it can be achieved that convert the high-precision of electric current input;Voltage conversion circuit 23 uses the voltage transformer of model ZMPT107, Effective decompression conversion to ac high-voltage can be achieved.4G wireless transport modules use ME909S-821, can be realized by usb communication With the information exchange of microcontroller 1, and by related data be sent to O&M backstage, realize to the long-range of 5 working condition of semaphore Management and maintenance.
In the present embodiment, since the leading-out terminal of 5 connection signal lamp 4 of semaphore uses the LZ1R-5.08 for being 14pin to connect Line seat, therefore detection device uses the LZ3RH-5.08 junction blocks of double 14pin, the in this way harness 1 of original connection signal lamp 5 can be with It remains unchanged, detection device and the company of signal lamp 5 and semaphore 4 can be realized in the harness 2 of newly-increased both ends connection LZ1R-5.08 It connects, joint connection in site is convenient.
The utility model does not influence original signal due to resistance only very small inside current converter circuit, the circuit Control and detection between machine 4 and signal lamp 5, and the detection device can preferable independent operating;Microcontroller 2 is led to by SPI Letter can obtain electric current, the voltage analog magnitude that detection chip 21 detects, and then judge the real-time work of each signal lamp 5 in real time Make state, and it can obtain the real time information of semaphore 4 by CAN communication, and judge semaphore or signal with reference to testing result The working or fault message of lamp 5.4G wireless transport modules 3 can not influence the same of crossing signals interconnection plane joint control When, realize the function that real-time detector data is uploaded to O&M backstage, corresponding data information includes the real-time current of detection, electricity Analog data, semaphore real-time running state, the dependent failure information tentatively judged etc. are pressed, O&M is carried out convenient for passing through backstage Shi Jinhang is monitored in real time and subsequent big data analysis.
Embodiment described above is only that the preferred embodiment of the utility model is described, not to this practicality Novel range is defined, and under the premise of the spirit of the design of the utility model is not departed from, those of ordinary skill in the art are to this The various modifications and improvement that the technical solution of utility model is made should all fall into the protection that the utility model claims book determines In the range of.
