Description

Technical Field

[0001] This utility model belongs to the field of heating jacket technology, specifically relating to a multi-channel intelligent temperature control box applied to a flexible surface heating system. Background Technology

[0002] Since pipeline heating systems often consist of multiple heating jackets rather than a single heating jacket, using a single-circuit temperature control system would require a relatively large number of single-circuit systems, making it difficult to flexibly expand to multi-area control, which is not conducive to centralized control and management, leading to an increase in overall costs.

[0003] The drawbacks of single-loop control systems are: 1. Poor scalability: They cannot be flexibly expanded to multi-zone control. Adding control loops requires additional equipment, increasing overall costs. 2. Difficult centralized management: Multiple single-loop controllers operate independently, requiring individual configuration via HMI or host computer, increasing system complexity. Since pipeline heating systems often consist of multiple heating jackets, using a single-loop temperature control system would require a relatively large number of single-loop systems, hindering flexible expansion to multi-zone control and making centralized control and management difficult, thus increasing overall costs. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a modular, integrated, visualized, simple to operate, low-cost, and easy-to-control multi-channel intelligent temperature control box for flexible surface heating jackets.

[0005] The purpose of this utility model and the solution to its main technical problem are achieved by the following technical solution:

[0006] This utility model discloses a multi-channel intelligent temperature control box for a flexible surface heating system, comprising a remote controller, a temperature control module, a hub, a relay module, a switching power supply, terminal blocks, a load power switch, a power circuit breaker, an input / output module, and a temperature control box. The remote controller is connected to the temperature control module and the hub via wires. The temperature control module is connected to the hub, the relay module, the switching power supply, and the input / output module via wires. The hub is connected to a human-machine interface via wires. The relay module is connected to the terminal blocks and the input / output module via wires. The switching power supply is connected to the terminal blocks and the host computer software via wires. The terminal blocks are connected to the power circuit breaker and the input / output module via wires. The load power switch is connected to the power circuit breaker via wires.

[0007] The input / output module consists of a power output module and a temperature acquisition module. The power output module is connected to the output terminal of the relay module via a wire, and the temperature acquisition module is connected to the temperature control module via a wire.

[0008] The host computer software connects to the human-machine interface and the remote controller via wireless signals. The remote controller is connected to the temperature control module via a hub.

[0009] The temperature control module is a temperature control module with a communication module.

[0010] The remote controller, temperature control module, hub, relay module, switching power supply, terminal block, load power switch, and power circuit breaker are installed inside the temperature control box.

[0011] Compared with existing technologies, this invention has significant advantages. As shown in the above technical solution: a remote controller connects to a temperature control module and a hub via wires; the temperature control module connects to the hub, a relay module, a switching power supply, and an input / output module via wires; the hub connects to the host computer software via wires; the relay module connects to the terminal block and the input / output module via wires; the switching power supply connects to the terminal block and the host computer software via wires; the terminal block connects to the power circuit breaker and the input / output module via wires; and the load power switch connects to the power circuit breaker via wires. The input / output module collects the temperature signal from the flexible surface heating jacket; the temperature control module reads the temperature signal and drives the relay module to output power to the input / output module, thereby driving the controlled flexible surface heating jacket to work; simultaneously, the remote controller and the human-machine interface read and write the temperature data from the temperature control module via the hub and display the temperature data on the host computer software and the human-machine interface, thus achieving data visualization and remote control. This invention uses the heating temperature of the flexible surface heating jacket as the parameter for output power control. The temperature control module achieves automatic temperature control of the flexible surface heating jacket through internal control, achieving effective and precise control and ensuring stable operation of the flexible surface heating jacket. The temperature control module employs a PID control algorithm, using a temperature acquisition module (such as a PT100 sensor) as feedback signal to output a PWM signal to drive the relay module. The relay module uses a solid-state relay (SSR), with the input signal being the switching output of the temperature control module, and the output terminal connected to the power output module to control the on / off state of the heating jacket. The hub, based on the RS485 communication protocol, enables multi-master data interaction between the remote controller, human-machine interface, and temperature control module, avoiding conflicts. Temperature acquisition: The temperature acquisition module monitors the heating jacket temperature in real time and transmits it to the temperature control module via analog signals. Control logic: The temperature control module compares the set value with the actual value and outputs a control signal to the relay module through PID calculation. Power output: The relay module controls the on / off state of the power output module, adjusting the heating jacket power. Data interaction: The remote controller and human-machine interface read and write temperature data through the hub, achieving remote monitoring. It achieves modular integration, visualization, and is simple and easy to operate and use. Attached Figure Description

[0016] The following detailed description, in conjunction with the accompanying drawings and preferred embodiments, describes the specific implementation methods, structure, features, and effects of this utility model.

[0017] This utility model discloses a multi-channel intelligent temperature control box for a flexible surface heating system, comprising a remote controller 1 (DAM0455-MT), a temperature control module 2 (model: DTE10T), a hub 3 (JY-DAM-485HUB), a relay module 4 (SSR-40DA), a switching power supply 5, terminal blocks 6, a load power switch 7, a power circuit breaker 8, an input / output module 9, and a temperature control box 15. The remote controller 1 is connected to the temperature control module 2 and the hub 3 via wires; the temperature control module 2 is connected to the hub 3, the relay module 4, the switching power supply 5, and the input / output module 9 via wires; the hub 3 is connected to a human-machine interface 13 via wires; the relay module 4 is connected to the terminal blocks 6 and the input / output module 9 via wires; and the switching power supply 5 is connected to the terminal blocks 6 and the human-machine interface via wires. 13. Terminal block 6 is connected to power circuit breaker 8 and input / output module 9 via wires. Load power switch 7 is connected to power circuit breaker 8 via wires. Input / output module 9 consists of power output module 10 and temperature acquisition module 11. Power output module 10 is connected to the output terminal of relay module 4 via wires. Temperature acquisition module 11 is connected to temperature control module 2 via wires. Host computer software 14 is connected to hub 3 and switching power supply 5 via wires. Human-machine interface 13 is connected to host computer software 14 and remote controller 1 via wireless signals. Remote controller 1 is connected to temperature control module 2 via hub 3. Temperature control module 2 is a temperature control module with a communication module. Remote controller 1, temperature control module 2, hub 3, relay module 4, switching power supply 5, terminal block 6, load power switch 7, and power circuit breaker 8 are installed in temperature control box 15.

[0018] In use, the human-machine interface 13 connects to the remote controller 1 via a wireless signal. The heating temperature can be set locally or remotely via the human-machine interface 13. The temperature setpoint is sent to the temperature control module 2 via the hub 3. Simultaneously, the temperature control module 2 acquires the current temperature value through the temperature acquisition module 11. The control program of the temperature control module 2 compares the current temperature value with the setpoint. If the setpoint is greater than the current temperature, the temperature control module 2 will drive the relay module 4, which will output power to the power output module 10, thereby driving the flexible surface heating sleeve. The host computer software 14 can write the station number and address of each control module, thus enabling communication and control with the temperature control module 2. Simultaneously, by writing the station number and address to the remote controller 1, communication and control between the human-machine interface 13 and the temperature control module 2 can be achieved. The remote controller 1 and the host computer software 14 both serve as master stations. To avoid conflicts between the two master stations, they are connected to the hub 3, which is then connected to the temperature control module 2. The hub 3 reads / writes the temperature data from the temperature acquisition module 11 via RS485 communication. The human-machine interface 13 can remotely read and write the data from the temperature control module 2, acquire data online in real time, and generate historical temperature curves and historical data tables.
